The technical field

The present invention relates to a navigation device, outstanding navigation instructions to the user depending on the recorded profile.

The level of technology

The navigation device of the prior art, constructed based on GPS (global positioning system), a well-known and widely used as car navigation systems. This navigation device, GPS based, refers to a computing device that is in functional connection with the external (internal) GPS receiver can determine its own global position. In addition, the computing device can determine a route between the start and end addresses that can be entered by the user computing device. In a typical embodiment, the computing device is capable of using the software to calculate the "best" or "optimal" route between the locations of the start and end addresses from the map database. The "best" or "optimal" route is determined based on pre-defined criteria and not necessarily the fastest or the shortest route. It may also be the preferred route based on travel from previous routes.

On hatzioannou device may in a typical embodiment, be affixed on the instrument Board of the vehicle, and can be implemented as part of the on-Board computer of the vehicle or car radio. The navigation device may also be (part of) a wearable system, such as a PDA or phone.

Using positional information obtained from the GPS receiver, the computing device may determine on a regular basis, their position, and can display the current position of the vehicle user. The navigation device may include a memory device for storing map data and a display for displaying the selected portion of the map data.

In addition, it can provide instructions on how to follow a particular route through the appropriate navigation instructions on the display and/or generated as a sound signal from a speaker (e.g. "turn left in 100 meters"). Chart depicting steps that must be performed (for example, an arrow to the left indicates left turn ahead), can be displayed in the status bar, and can also be independently imposed on the corresponding junction/turns, etc. on the map.

The well-known ability of car navigation systems before the conduct of the driver, when he is driving along a route calculated by the navigation system, to trigger the re-calculation of the route. This is useful when on the road car meet road works or a large automobile congestion.

Well-known ability to provide the user an opportunity to choose the type of algorithm to calculate the route used by the navigation system, by selecting, for example, the "normal" mode and a "fast" mode (which calculates the route in the shortest time, but does not explore the many alternative routes as in normal mode).

Also well-known for the ability to calculate the route with user-defined criteria, for example, the user may elect to review the route, which should be calculated by the device. Device software then calculates various routes and assess the most preferred of which contain along the route with the greatest number of points of interest (known as POI), who noted, for example, as being picturesque architecture.

Patent application EP 1530025 A2 discloses a navigation system of a vehicle, which is made with the opportunity to study the habits/preferences of the user. The navigation system of the vehicle observes the habits of the waters of the indicator and updates the database, in order, therefore, to make the navigation system of the vehicle to contain the preference for the habits of the driver, so that the navigation system is better suited to routes that are desirable specific drivers when travelling to certain destinations. The navigation system contains a special module of artificial intelligence (AI), performed with the opportunity to observe the habits of the driver. The main reason for tuning the user desire is to prevent irritation of the user. However, the direction of the driver in an undesirable direction is only one case of irritation of the driver.

Another even more important case of irritation is the way that issued the instruction. If, for example, the navigation device tells the driver, "go left at the next intersection", it can be irritating for the driver who knows very well this intersection. This case irritation cannot be prevented in these navigation devices.

Short description

Thus, it is desirable to provide a navigation device that generates navigation instructions that reduce the likelihood of irritation to the user.

Therefore, according to the aspect of the claimed invention provided navigationsleiste, made with the possibility to give navigation instructions to the vehicle driver, the device contains:

module calculate a route that has a capability to determine a route from a departure point to a destination;

module instructions executed with the ability to create a set of basic instructions for the driver to allow the driver to travel on a particular route; and

module profile made with the possibility to build at least one profile, characterized in that the navigation device includes:

translator profile-the statement"made with the possibility to convert a set of basic instructions into a set of output instructions in dependence of said at least one profile.

The profile may, for example, contain so-called profile of the driver in which you saved the settings that reflect the preferences, properties, or habits of the driver. Depending on the recorded values for these parameters, the navigation device converts basic instruction in the output instruction issued by the driver. Since the profile of the driver is built and will change over time, sometimes certain basic instructions will be transformed in any other way than at other times. How to change display instructions also called the fast "adaptation" of instructions. The combination of the two technologies, i.e. build profile and adaptation of navigation instructions, makes the navigation device according to the invention, more personally-oriented navigation tool. Providing correct instructions specific driver can promote safer behavior.

In another aspect of the invention provides a method of providing directions for navigation using the navigation device, the method includes:

- determining the route from a departure point to a destination;

- creation of a set of basic instructions to the user to allow the user to travel on a particular route; and

Detailed description

Figure 1 shows a schematic block diagram of a variant of implementation of the navigation device 10 containing the processor 11 to perform arithmetic operations. The processor 11 is configured to be connected with the memory blocks that store instructions and data, such as a hard disk 12, a persistent storage device (ROM) 13, an electrically erasable programmable permanent memory (EEPROM) 14 and a random access memory (RAM) 15. The memory blocks may include map data 22. These map data can be two-dimensional map the data (latitude and longitude), but can also contain a third dimension (height). The map data may further comprise additional information, such as information about petrol/gas filling stations, points of interest. Map data can also contain information about the shape of buildings and objects along the road.

The processor 11 can also be made with the ability to connect to one or more input devices, such as keyboard 16 or the mouse 17. The keyboard 16 can, for example, be a virtual keyboard presented on the display 18, which is a screen sensitive to touch. The processor 11 can optionally be configured to contact one or more output devices, such as display 18, a speaker 24, and one or more blocks 19 are read in order to read, for example, floppy disks 20 or the CD-ROM 21. The display 18 may be a conventional computer display (such as LCD), or may be a projection display type, such as located at the level of the windshield display that is used for projection of instrumental data on the windshield or wind shield of the car. The display 18 may also be display, made with the ability to function as a touch screen that allows the user to enter instructions and/or informationbest touching the display 18 with his finger.

The speaker 24 may be implemented as part of the navigation device 10. When the navigation device 10 is used as a car navigation device, the navigation device 10 may use car audio speakers, on-Board computer or the like.

The processor 11 can additionally be made with the ability to communicate with the device 23 positioning, such as GPS receiver, which provides information relative to the position of the navigation device 10. Under this option, the exercise device 23 positioning the device 23 positioning GPS based. However, it should be understood that the navigation device 10 may be implemented by any type of technology location and is not limited to GPS. It can be implemented using other types of GNSS (satellite system global navigation), such as the European system Galileo. Also it is not limited to systems determine the position/speed satellite-based and can also be deployed using ground makovich signals or any other type systems that allow the device to determine its geographic position.

However, it should be understood that they may be presented with other or different number nl is kami memory input devices and readers, well known to specialists in this field of technology. In addition, one or more of these devices may be physically located remotely from the processor 11, if required. The processor 11 is shown as one block, but it may contain multiple processors that operate in parallel or controlled by one main processor, which may be located remotely from the other, as is well known to specialists in this field of technology.

The navigation device 10 is shown as a computer system, but can be any signal processing system with analog and/or digital and/or software technology made with the possibility to perform the functions described in this document. It should be understood that, although the navigation device 10 shown in figure 1 as a set of components, the navigation device 10 may be implemented as a single device.

The navigation device 10 may use the navigation software, such as navigation software from TomTom B.V., called the Navigator. Software Navigator can run on Pocket PC PDA device with a touch screen (i.e., running the stylus), such as the Compaq iPaq, and any other devices that have built-in GPS reception is IR 23. The combined system of the PDA and the GPS receiver is designed to be used in the navigation system in the vehicle. Options exercise can also be carried out in any other form of navigation device 10, such as a GPS receiver/computer/display, or device designed for use outside the vehicle (e.g., for pedestrians or vehicles other than the vehicle (e.g. aircraft).

Figure 2 depicts an example of a functioning display 18 of the navigation device 10 that is described above.

Navigation software, when running on the navigation device 10, the display shows the normal navigation mode, the display 18, as shown in figure 2. This species may provide instructions to control the vehicle using a combination of text, symbols, voice prompts and roaming the map. Key elements of the user interface are the following: 3D map, which occupies most of the screen. Note that the map can also be displayed as a 2D map.

Map shows the position of the navigation device 10 and its immediate environment, rotated so that the direction in which the navigation device 10 is moved, always aimed "up". Line 2 state of mo is et to pass through the screen in the bottom quarter of the screen. The current position of the navigation device 10 (which the navigation device has determined independently using traditional GPS positioning) and its orientation (which is inferred from the direction of motion) position shown by the arrow 3. Route 4, calculated by the device (using the algorithms calculate the route stored in the devices 11, 12, 13, 14, 15 memory as applied to the map data stored in the map database in the devices 11, 12, 13, 14, 15 memory), shown as a darkened path. Route 4 all the basic steps (for example, rounding bends, junction, roundabout junctions and the like) is shown schematically by the arrow 5, superimposed over route 4. Line 2 status also includes a left side schematic icon depicting the following step 6 (in this case, turn to the right). Line 2 status also shows distance to next step 6 (for example, turn to the right here the distance is 190 m) as extracted from the database of the entire route, calculated by the device (i.e. from a list of all roads and related actions specified route). Line 2 status also shows the name of the current road 8, remaining travel time 9 (in this case 35 minutes), the actual estimated time 28 arrived the Oia (16:50) and distance to destination, 29 (31,6 km). Line 2 States can optionally display additional information, such as the power of the GPS signal indicator light in the power style like used in mobile phones.

As already mentioned above, the navigation device 10 may include an input device such as a touch screen that allows the user to cause the navigation menu (not shown). From this menu can be initiated and managed other navigation functions. Resolution selecting the navigation functions from the menu screen, which themselves very easily invoked (for example, one action from the map display to the menu screen), greatly simplifies the user interaction and makes it faster and easier. The navigation menu includes options for the user to enter the destination.

The actual physical structure of the navigation device 10 itself is fundamentally may not be different from any traditional handheld computer, except integrated GPS receiver 23 or GPS data received from an external GPS receiver. Therefore, the devices 12, 13, 14, 15 memory store algorithms for computing the route, a map database and software user interface; a processor 12 interprets and processes the user is input (for example, using the touch screen) to enter the start and end addresses and all other input of control commands, and applies the algorithms of the calculation of the route in order to calculate the optimal route. "Optimality" can refer to criteria such as shortest time or shortest distance, or some other associated with a user factors.

More specifically, the user enters the desired destination in the navigation software running on the navigation device 10, using the provided input devices such as touch screen 18, the keyboard 16 and the like, the User then selects a method, which will be calculated route: various modes, such as "fast" mode, which calculates the route very quickly, but the route may not be the shortest; "full" mode, which loops through all possible routes and selects the shortest, but longer calculation time, etc. are other options available to the user-defined route, which is a picturesque, for example, passes through many POI (points of interest)that are marked as types with picturesque architecture, or go through a number of POIs of possible interest to children, or uses the least number of road crossings, etc.

aviacionnoe device 10 may further comprise a device 25 I / o, which provides the navigation device 10 can communicate with remote systems, such as other navigation device 10, personal computers, servers, etc. via the network 27. Network 27 may be a network of 27 any type, such as LAN, WAN, Bluetooth, Internet, intranet and other Communication may be wired or wireless. Wireless communication may, for example, to use RF signals (radio frequency) and RF network.

The invention also relates to a vehicle 40, such as a car, containing the navigation device 10, described above, see figure 3. The navigation device 10 may, for example, be integrated in the instrument panel of the vehicle 40 or attached on the front window.

Roads themselves are described in the map database, which is part of the navigation software (or otherwise available), running on the navigation device 10, as lines, i.e. vectors (e.g., start point, end point, direction for the road, fully road is made up of many hundreds of such sections, each uniquely defined by start point/end point, direction). A map is then generated from these vectors roads, plus points of interest (POIs), plus the names of the roads, plus other geographical elements such as Park boundaries, borders, rivers and so on, everything nor are given in terms of vectors. All map elements (e.g., vectors roads, POI, etc) are specified in a coordinate system that matches or relates to the coordinate system of GPS, allowing you to place the position of the device, as defined through the GPS system, the corresponding road shown on the map.

The calculation of the route uses complex algorithms that are part of the navigation software. The algorithms are applied in order to calculate a large number of different potential routes. Navigation software then evaluates them by user-specified criteria (or the default settings of the device), such as scanning in full mode, with the route through the scenic, historic museums and without cameras speed measurement. The route that best matches the specified criteria, and then calculated by the CPU 11 and then stored in the database in the devices 12, 13, 14, 15 memory as a sequence of vectors, names of roads and actions that must be performed on the endpoint of the vector (for example, corresponding to the predefined distance along each road on the route, for example after 100 meters turn left to the street.

To reduce the chance of irritation, the navigation device 10, according to the invention,produces a more accurate navigation instructions, than real navigation device. To do this, the navigation device 10 collects data about the driver and uses these data to produce accurate instructions. As data is collected and used, is described below with reference to figure 4-7.

Figure 4 schematically shows some of the modules contained in the navigation device 10 according to a variant embodiment of the invention. In this embodiment, the navigation device 10 includes a module 41 calculation of the route which has a capability to determine a route from a departure point to a destination using map data from the map database 39 data and information entered by the user. In addition, a module 42 instructions, receiving input data from the module 41 calculation of the route, see arrow 43, and is made with the ability to create a set of basic instructions in order to allow the user to travel on a particular route. An example of a basic statement is "20 m to the RIGHT", meaning that after 20 meters, the driver must turn right.

Also provided by one or more modules of the profiles, which are made with the ability to build one or more profiles, as will be described in more detail below. In this embodiment, the modules of the profiles contain component 44 in place of the profile of the driver, builds a profile of the driver component 45 profile design relating to the environment, builds a profile relating to the environment, and the component 46 build route profile, build a profile of the route. The corresponding profiles are stored, for example, in storage device 12. Provides interpreter 48 "profile statement", which takes a set of basic instructions, see arrow 51, created by the module 42 of the instructions and reads one or more profiles from the storage device 12. Translator 48 "profile statement" has access to the database 70 of these instructions for the person in which you saved the possible human instructions. An example of instructions for a person is "turn right" or "follow the spread.

The navigation device 10 also includes a device 50 output, which receives the output instructions, see arrow 57, the translator 48 "profile statement". The device 50 output may contain speaker 24 or screen 18 shown in figure 1, or any other suitable output device.

The navigation device 10 may also contain a component 52 recognition of the driver, which is designed with the ability to recognize the driver sitting behind the wheel of the vehicle 40. After the navigation device 10 is enabled, the component 52 recognition of the driver recognize the AET driver and user ID, see arrow 60, is passed to the component 44 building a profile of the driver. The driver can be detected using other technologies. The user can, for example, be recognized by its name, selected on the touch screen 18. It can also be recognized by the number of his mobile phone, transferred to the navigation device 10 by means of phone. As should be clear to the expert in the art, other means, such as a car key, wireless, with a tag chip, etc.

Also provided by the recording device 62 of the driver, which is performed with the opportunity to record the so-called parameters of the driving style of the vehicle, which reflect the behavior of the driver. The recorded values of these parameters driving style, see arrow 63, passed component 44 building a profile of the driver. The recording device 62 driver is configured to continuously collect data on the manner of driving of the driver. Component 44 profile design, the driver will use the parameters of the driving style in order to build a profile of the driver or to improve the active profile of the driver. The parameters of the driving style can be collected even without the programmed route.

Possible parameters of the driving style, which can be recorded and Eridani component 44 building a profile of the driver, to build the profile of the driver are:

1) acceleration factor: that is, a moving average of acceleration of the vehicle (m/s2)divided by a predetermined maximum acceleration;

2) the coefficient of braking: that is, a moving average deceleration (m/s2) of the vehicle for braking coefficient (m/s2)divided by a predetermined maximum braking;

3) the coefficient of aggressive cornering: that is, a moving average of acceleration in the rotation during the rotation (m/s2)divided by a predetermined maximum acceleration in the rotation;

4) the number of times that the driver rides in a separate administrative region (for example, Paris, hometown, place of work).

After the driver is recognized by the component 52 recognition of the driver component 44 profile design, the driver considers appropriate driver profile from the storage device 12. If the driver uses the navigation device 10 for the first time, the component 44 profile design, the driver will build a complete new profile of the driver or install a predefined profile already stored in the navigation device 10. Component 44 building a profile of the driver m is likely to have the ability to store profiles of drivers for multiple drivers and can provide either an automated, or manual option to switch between them. A driver profile can be saved in separate files or in the database structure, enabling the addressing of the individual driver profile, assigning the corresponding index of the user. As a driver profile can contain personal data communication, such as wireless ID tag number or ID of a mobile phone or other personal instruction to uniquely select a user, such as fingerprint or password, and driver profile can also be addressed with these data. In the embodiment, the user may be able to identify themselves by manually selecting my profile from the list shown on the screen 18.

A driver profile can contain one or more of the following parameters of the driver that have values between, for example, 0-100:

A. home address;

B. ID driver;

C. date of birth;

D. the number of times that the administrative area was visited;

E. percentage of congresses, ignored by the driver: 0...100;

F. the driver turns left instead of turning right: 0...100;

G. the degree of aggressiveness: 0...100;

H. mobile phone number;

I. the driver makes a phone call right now: 0 (No) or 100 (Yes);

J. the complexity of driving conditions 0...100;

K. driver does not want to receive instructions what about the navigation in the location of your home (or any recent destination: 0...100;

L. the sensitivity of the driver to the current day of the week: 0...100;

M. the sensitivity of the driver to the time of day: 0...100.

The following explanation will describe how the values of the parameters of the driver can be determined or calculated.

A. home address: street, city and country are entered manually;

B. ID of the driver: the name or number or personal code;

C. date of birth: manually entered by the driver;

D. the number of times that the administrative area was visited: many pre-defined areas, such as towns, stored in memory, and the counter is incremented each time the driver goes to one of the predefined areas;

E. percentage of congresses, ignored by driver: 100×moving average of the number of ignored congresses/total number of congresses in the programmed route;

F. the percentage of turns, where the driver turned left, turning right, or Vice versa: a moving average of 100×the number of times the instruction rotate left or right was misinterpreted by the driver/the total number of turns within a sliding window of a predefined number of hours drive (preinstalled in 100 hours);

G. the degree of aggressiveness: 100×(coefficient of aggressiveness rotation + acceleration factor + factor inhibition)/3;

H. mobile phone number: enter the BP is know or read from the mobile phone;

I. the driver makes a phone call when scheduled conclusion statement: if a telephone connection, SMS read, or read aloud, or any other remote communication with the person detected by the system, this value is set to 100, otherwise 0;

J. the complexity of driving conditions: (coefficient precipitation + coefficient wind + coefficient road conditions + coefficient of the road)/4, while the ratio of precipitation is equal to 0 (dry weather), 20 (rain), 60 (deg) or 80 (snow), and the coefficient wind=0 is a linear function of the number of BFT, where 0 is windless and 100=8 BFT or more, and the coefficient of road conditions 0 (dry), 50 (wet), 100 (slippery), and the coefficient of the road is equal to 0 (free), 40 (middle), 70 (busy), 100 (with traffic);

K. driver does not wish to receive navigation instructions in a location of your own home (or any recent destination: this parameter is initially set equal to 0 for each scheduled destination. Then every time you drive along the route from or to that destination, it increases by 5 up until he eventually reaches 100. However, the value may decrease by 1 each day, when the driver moves from or to this destination. As a result, over time, the value can reach and stay at 0;

L. case the sensitive driver to the current day of the week: "Event" is each case, when the route of a vehicle differs from the programmed route. The relative variance (standard variance divided by the mean) of the event in relation to the day of the week is calculated as:

In this example, X represents the number of events per day, M is the average of all days of the week, N = the number of days of the week (7). If the divergence events are equally divided by days of the week, then this coefficient = 0. If the driver makes mistakes only on Monday, this factor = 100. If the driver makes mistakes only on Mondays and Tuesdays, this value will be 64. The ratio of 2.65 is only a scaling factor.

M. the sensitivity of the driver at the time of the day: use the same formula as referred to in paragraph G, where X represents the number of events in the quarter of the day: morning, noon, evening, night, M is the average of all quarters of the day, N = the number of quarters of the day (4). If the divergence events are equally divided into morning, noon, evening and night, then this coefficient = 0. If the driver makes mistakes only during the night, this factor = 100. If the driver makes mistakes only in the mornings and nights, this value is 64.

Component 45 profile design relating to the environment depicted in figure 4, continuously discretetime possible relating to environment the data is, called environmental parameters. Possible environmental parameters and their values are:

A. road conditions along the route, value: (dry, wet, slippery)

B. weather conditions, value: (dry/rain/hail/snow) and wind 0-100) (100 equal to 8 BFT or more)

C. daylight, value: (light, dusk, darkness)

D. time of day is: (morning, noon, evening, night)

E. time of year, is: (spring, summer, autumn, winter)

F. the day of the week is: 0-6.

Road conditions and weather conditions can, for example, be received from a remote server, and information about daylight may, for example, be determined using the geographic location of the navigation device 10 and/or via a light sensor. The time of day, time of year and day of the week can be calculated from the present time, the particular internal clock, not shown, the navigation device 10.

Component 46 build route profile is configured to continuously discretize the possible relating to the route data, call routing options. Possible route options and their values are:

1) traffic conditions on the route, value: (loose, medium, busy, congestion);

2) the road type, the value (highway, secondary roads, city driving).

Conditions on the range of motion can for example, to be read from a remote server or receiver of data on road traffic and road type can be read from the map database 39 data, see arrow 38.

After the driver has programmed route, each time when the driver ignores the instructions for navigation or spontaneously rejects its course from the route, the component 44 profile design, the driver can record one or more of the following response options navigation:

1. The importance of skip instructions, this value can be computed using the extra distance to get back on the route.

2. The number of times (percentage)that the driver actually takes place when reported after ignoring instructions for navigation.

3. The GPS location and the actual rate plus the original course. They will be sent to the remote server. If many drivers have the same problem in a particular location, map data may be incorrect. The remote server may store them in the database system. After manual or automatic check of records in the system database can be concluded that the database for this GPS location is defective, or the map database has other disadvantages. The server can respond navigation device 10 a message that particularly the e GPS location should be ignored so, to update the profile of the driver cannot be performed when the driver fails to follow the instructions until the map data is replaced with the new version.

4. The current volume of the voice instructions, the value of 0-100.

5. The number of times that issued the instruction "turn around when possible".

6. The velocity (v) in (m/s) from the GPS receiver and/or wheel/drive sensor(s).

7. The actual distance from the home location of the driver.

8. Left movement, right movement in the place of residence or Vice versa (Yes/no).

9. The number of errors, which makes the driver when he goes left, when the instructions said "right"and Vice versa.

10. The number of times the exit skipped.

11. The number of times skipped street (left/right).

12. The number of spontaneous deviations (left or right without instructions).

13. GPS coverage and accuracy at the time when the statement is ignored, value: 0 = no data 100 = fine.

In the embodiment, the event in which the driver ignores the instructions are written and accompanied by additional data such as time stamp and location. The navigation device 10 is configured to create and store a list of obscure locations, where the driver may be confused by the current situation or possible errors SD card is raficheskih data. A list of obscure locations can be automatically cleared so that will only events, not more than 1 year. This list is taken into account each time a driver traveling on the route. If the driver was going listed in this location, then navigation instructions adapted to avoid additional errors, based on the number of times a location was listed. The number of times that the driver made an error in this location, must be >=2. If so, the driver may need to be adapted instructions. In the embodiment, the parameters of the driver "percentage of congresses, ignored by the driver and the percentage of turns, where the driver mistakenly turned left instead of right or Vice versa will be temporarily multiplied by 2 during the period when the driver is closer than 1 km to the location in the list of obscure locations. Increasing the value of the two parameters of the driver, the profile of drivers changes to the profile "more uncertain" for the driver who needs more output instructions.

Component 44 building a profile of the driver, under option exercise performed with the opportunity to build a profile of the driver using one or more parameters of the driving style and the return of the navigation parameters described above. Built user profile C is the sent to the translator 48 "profile statement", which converts the generated set of basic instructions depending on the profile of the driver, as will be explained later.

According to another variant implementation of the navigation device 10 does not contain component 44 building a profile of the driver, and instead contains only the 45 profile design relating to the environment, which builds a profile related to the environment. An example of such a profile of the environment and its parameters is:

A. road conditions along the route, value: (dry, wet, slippery)

B. weather conditions, value: (dry, rain, hail, snow and also wind strength in BFT 0=no wind, 100=8 BFT or more)

C. daylight, value: (light, dusk, darkness)

D. time of day is: (morning, noon, evening, night)

E. time of year, is: (spring, summer, autumn, winter)

F. the day of the week value: 0 = Sunday to 6 = Saturday.

Note that this profile environmental executed by parameters related to the environment, already discussed above. The profile of the environment will be passed to the translator 48 "profile statement", see arrow 55 in figure 4, which will be used related to the environment profile to convert basic instructions.

In another embodiment, only the route profile is built and sent to the translator 48 "Pro the e-instruction" component 46 build a route profile. An example of a route profile contains all the settings of the route described above.

A. traffic conditions along the route, value: (light, medium, busy, congestion)

B. the type of road, the value (highway, secondary roads, city driving).

According to a predefined variant implementation of the component 44 profile design, the driver takes the values related to the environment parameters from the component 45 profile design, environmental profile, see arrow 64, and the values of the parameters of the route from the component 46 build route profile, see arrow 65. Combining, for example, relating to environment settings with parameters of the driving style, the component 44 profile design, the driver is able to "see"why the driver acts in a certain way. For example, if weather conditions are extreme, and the driver was going very slowly on the highway, it makes no sense to fit the current profile of the driver so that the profile has changed profile "quiet driver". In such situations, the driver profile is not corrected and remains reliable. Additional, related to environmental parameters can also be used to see how the driver reacts to external stimuli such as rain, etc. and save this information in the profile of the driver.

omponent 46 build route profile made with the possibility to discretize the conditions of the road, reading, for example, data from a remote server or receiver for traffic data. Traffic conditions can also be transmitted to the module 41 calculation of the route, see arrow 66 in figure 4. Conditions 66 traffic can be used to re-calculate the route taking into account traffic jams, etc. as would be known to a person skilled in the technical field.

According to a variant implementation of the translator 48 "profile statement" will take into account the profiles stored in memory, and converts the basic instructions in the K output instructions, where K= 0, 1, 2, 3. Also you may play an additional sound in situations where it is appropriate according to the current profile, for example, the alarm, when the driver must get off, while he's talking on the phone.

In another embodiment, the translator 48 "profile statement" made with the possibility to delete the statement of the standard instruction set. For example, a warning that this route is a route with a speed of 50 km/h, it is not necessary to issue the driver is very familiar with this route, which is also not an aggressive driver.

In another embodiment, the translator 48 "profile statement" made with the ability to change the output statement. Periods what to 48 "profile statement" may, for example, change the voice used for the pronunciation of the output statement, or change the volume of the pronunciation of the displayed instructions. In addition, it may be possible to change the time displayed instructions. Navigation instructions can be given earlier or later than specified in the standard instruction set 51. This can be useful in situations in which the traffic is very busy, and it is almost impossible to change lanes. In such cases, drivers can take the earlier instructions. The distance between the point at which the instruction is issued, and the route point, associative associated with the instruction, may also be changed depending on the profiles. For example, if the weather is bad, and/or if the driver is inexperienced, a particular instruction can be issued before a specific intersection or exit. The way that issued a separate statement, also can be changed. Instruction type "go left" can be changed to "you really should go to the left for the driver profile that indicates that the driver not only tend to ignore or forget the instructions for the exit, but also needs more attention, as it goes in the new area. The voice used to deliver instruction, can also be changed from male to Jens is s or Vice versa in cases when the profile indicates that you need more attention, because drivers who drive aggressively, can be slowed down by a female voice. In addition, according to another variant implementation, changing the intonation used voice. More friendly or aggressive tone when the drive appears to be as sensitive to time of day or day of the week. More aggressive voice can be useful when the previous one additional instructions did not have sufficient effect, as the driver again missed the conference, or when the costs to allow deviation from the route are relatively high. Alternatively, it may be changed the volume instruction(s). If Congress missed recently, and the volume is relatively low, the volume can be made higher. If the driver ignores the conventions, additional instructions and sounds can be created on the important congresses. For those missed meetings, which are important in terms of the cost of the return on the route, i.e. it is necessary to pass relatively many miles, the instructions may be different (e.g., louder)than for other less important congresses. If the driver is not aggressive, and it seems that the driver will follow the instructions (such as the driver, who travels frequently in the neighborhood), verbal instructions can be skipped. If the driver rides the l a lot of the location of his house, preliminary announcement (forward, take a left, then take right) can be ignored, then skipped all ads (forward, take a left, then missed all oral instructions.

If the driver is in a difficult driving conditions (for example, relating to environment profile specifies the rain), prior notice may be removed from the standard instruction set 51. If the driver is sensitive to time of day or day of the week (missed each instruction is listed in the profile by using the time stamps, thus, the prediction can be made using this information), are given more detailed instructions, for example, the driver known that he misses congresses at night, in winter or in the afternoon on Fridays. If the driver is talking on the phone, additional attention may be attracted by the play, for example, sound. If the driver is turning left instead of turning right, may be issued additional instructions to emphasize left or right (for example, "go to the right, nearest the turn").

In the embodiment, the volume of output instructions is increased, if the profile of the driver indicates that the driver makes a phone call when scheduled output instruction. Alternatively, loudly the industry can be reduced, for example, if the profile of the driver indicates that the driver never ignores/forgets congresses or turns, when the driver makes a phone call.

In the embodiment, the driver has the ability to disable the adaptive navigation instructions by manually selecting it in your user profile. Also, if the driver thinks that the system does not treat it the right way, it may be possible to reset the profile to factory settings, resulting in the default user-friendly way of presenting instructions.

Below is a series of simplified but detailed examples of the way that works the invention, with reference to figure 5 and 6 and table.

The table shows an example of the passage of the profile of the driver, whose name is "Phil", 58 years old, male, living in Amsterdam, working in the Hague. Phil had never traveled on the route Amsterdam-the Hague, which has 2 exit way back home also has 2 exit, see figure 5.

Scenario A: instructions about the location of the house or recent destinations

Parameter driver "the driver does not want to receive navigation instructions at the location of his house or recent locations" for each destination will initially be 0, resulting in "original" set of output instructions in the numerical route. After a trip to work within one week the option of the driver, for example, will have a value of 5×5% = 25. After one week of vacation value can be reduced to 25-7×1% = 18%. This value can rise up to 100 over the average working year. Will be taken into account routes to a predefined location of the house, as well as routes to recent destinations. Each destination has its own counter. You will add new destinations that are counter to 0.

Translator 48 "profile statement" can use the value of the driver does not want to receive navigation instructions at the location of his house or recent locations"to reduce the number of instructions compared to the original set of output instructions.

A pre-defined limit, the driver does not want to receive instructions on navigating to the location of his house for accommodation can be pre-installed in 30%, thus, as a result, the second working week will be the result of 43%in excess of this limitation. Consequently, there is less of instructions, when the driver enters the region of his native city. The polygon map that defines this area can be obtained from the map data as polygons of the city of destination and hometown stored in them. Instructions to be skipped may be, for example, "3rd Congress" after the statement "at the roundabout turn left" or "you have arrived at your destination".

If Phil will lose a few more weeks, then the value of the driver does not want to receive navigation instructions at the location of his house" can slowly to fall below the limit, and instructions at home and at work will be original, to deliver again more instructions.

Scenario B: missed congresses

In this example, the factor "driver is sensitive to the day of the week" and "the driver is sensitive to time of day" are both equal to 0. The number of missed congresses initially equal to 0. After a trip to work within one week Phil took 20 congresses during this period and never missed one. Thus, his account of missed exits still 0%.

The following scenario describes Phil after a hard Sunday night party the next morning on Monday. He missed the exit, though he must hear the standard instructions. Now, as a result, the driver is sensitive to the day of the week"as well as "the driver is sensitive to time of day, both equal to 100. He missed 1 out of 21 congresses that has an account about 4%. If the next morning he bypasses Congress again, "the driver the feeling is sustained fashion to the day of the week" is set to 64, and the option "driver is sensitive to the time of day" remains 100. He also missed 2 of 22 congresses that has an account in 9%. There may be a pre-defined limit of 8%, which allows the algorithm to generate adaptive instructions for missed meetings.

The instructions on the morning of Tuesday were the same as on Monday, as the expense of missed congresses was equal to only 4% on Monday. The instructions are not adapted.

Instructions for the morning in the environment will not be the same as Tuesday, as Phil missed 9% of congresses, which is greater than the limit of 8%. Option "driver is sensitive to the time of day is equal to 100%, while the predefined limit may be 50%, thus, may be given additional instructions such as "take exit ahead", "after 100 meters take exit", "do not forget here to take advantage of the Congress.

Instructions on the evening of the following Monday and Tuesday during the drive home will be the same as in the morning this environment, due to the fact that it is Monday or Tuesday, even if it's not morning. Monday and Tuesday both have a score of 1 missed the exit, resulting in ending account option "driver is sensitive to the day of the week" in 64%. For the record, if Phil also ignores Congress on Wednesday, then the parameter "driver the feeling is sustained fashion to the day of the week" falls to 47%. It has no additional instructions for missed meetings.

Scenario C: Phil goes smoothly

In this example, Phil was now going on its work for some time. Knowing about the price of gasoline, it will smoothly accelerate your vehicle, and time will throttle before braking. Acceleration is measured in (m/s2between the time when the velocity is 0 (m/s), and the first time, when the speed is equal to 90% of the maximum. It is stored as a moving average with a predefined number of discrete values, such as 100 consecutive discrete values. Phil goes smoothly from 0 to 50 (km/h) for about 15 seconds, producing a smooth acceleration of 0.93 (m/s2). This value is saved for the moving average algorithm. Thus, it can be saved 100 discrete values, and when a new discrete value, the oldest will be deleted. The minimum limit for aggressive acceleration can be 0.5 (m/s2), and the maximum acceleration can be 5,0 (m/s2). Since this is the first discrete value, the average value Phil is now 0,93. Phil will have a coefficient of aggressive acceleration(0,93-0,5)/(5,0-0,5) = approximately 9%. When Phil is inclined slightly to accelerate, it can travel at speeds from 0 to 50 (km/h) in 5 seconds, producing an acceleration of 2.8 m/s2). His average those who er is equal to 1.85 (m/s 2), producing a new value for the parameter aggressive acceleration at 30%.

For use of the brakes is calculated and processed by the same factor aggressive braking. The acceleration will be negative, but the processing is the same as for the above parameter aggressive acceleration. Here it is assumed that Phil uses the brakes in the same manner as the gas pedal, to deliver aggressive braking 30%.

For bends in the road, every turn in more than 30 degrees, the speed and the turning radius is measured and converted into a centripetal acceleration (m/s2) and is also stored in the moving average value. Phil saves on the costs of maintenance and repairs on its rubber tires, the roadway turns smoothly. The stretch of road with a circular motion with a radius of 70 (m) (obtained from map data) protaetia when riding in Amsterdam with a speed of 50 (km/h). This is the centripetal acceleration of 2.8 m/s2). The minimum limit for aggressive acceleration can be defined as 1 (m/s2), and the maximum limit may be defined as 10 (m/s2), so Phil has a value of aggressiveness of rotation (2,8-1)/(10-1)=20%. If he travels at the same speed on the road segment with a circular DV is cutting a small 35(m) radius he will have a score of 50%. These values are stored in the moving average and can be taken into account later.

Applying the three factors of aggressiveness Phil (acceleration, braking and moving average of acceleration in the curve) exists to classify the current driver as "quiet", "normal" or "aggressive" depending on the average values of both coefficients. The lower range of values for the coefficient of aggressiveness can be 0%-30% for calm drivers, the average range can be 30%-70% for "normal" drivers and a high range can be 70%-100% for "disgruntled" drivers. Phil will be classified as "quiet" driver with his average of 27% from the coefficient of aggressive acceleration at 30%, aggressive braking in 30% and coefficient of aggressive acceleration at the turn of the 20%.

There are some exceptions, in this case, the average value of the Phil will not be affected. When the component 46 profile design, environmental profile, 44 instructs the build profile of the driver that the current traffic conditions are "busy", or the road conditions are slippery, or weather conditions are "storm", the measured value may not be processed. The reason behind this, that this is not normal is inoe behavior, and the behavior caused by the influence of external stimuli. When building a personal profile driver external stimuli should have a minimal impact on these values. Also, when GPS coverage and accuracy below certain acceptable limits, the driver profile is not changed, when can be expected that this "observable behavior" error caused by bad positioning of the GPS receiver 23.

In conclusion, the classification of Phil as a "quiet driver" (i.e. relatively low coefficient of aggressiveness will lead to others following navigation instructions. When Phil is not in a hurry or does not go aggressive, he may want the instructions for it were declared a certain number of times, to have time to react to these instructions. For example, the standard instruction to leave the highway, "after 800 meters take exit" can be declared as "take exit ahead", "use the right lane for exit" or "exit ahead, please zamedliteli time and take the right lane". Also when approaching a section of road with a roundabout Phil may be issued an additional statement "you can safely use right lane" in addition to "on the road with a roundabout, turn left, 3rd Congress". If Phil has a "normal is th" classification, change instructions will not apply. If Phil leads according to the classification of "aggressive", he will receive less statements, as they may not be spoken aloud in the short time between the approximation and the achievement of a certain point for instructions. Phil may need a short and clear statement of the type "go to the left after 100 metres", "roundabout, turn left" when "aggressive" driving.

Scenario D: Phil ignores the special instruction in a particular place

Phil loves to ride along the river in his hometown, so when he is sent to some destination, he prefers the route, which runs for some time, along the river, if he does not take too much extra time. This means that every day Phil again ignores some instructions on navigation in the same place. It takes only a few minutes and a few hundred meters. In the example he's going to work, and offer instruction is riding right on the circular motion, see figure 5. Phil loves the coastal route and goes to the right in a circular motion. The number of times ignore this individual statements in this particular location is calculated. When this number exceeds a certain predefined limit, such as 10 times, the location is marked to assume that it has a reasonable alternative. This label will be executed only when additional time is needed to bypass less than a predefined limit of 10% of additional time or additional distances. Next time, when Phil goes to work, he get the same instructions on the screen but they will not be spoken aloud when approaching a circular movement, as Phil will probably ignore them. It will be only annoyed by the statement, as it has its own personal preference for this small deviation.

According to a variant implementation of each basic instruction is converted into K output instructions, where K>=0 and K depends on the data in one or more profiles. If K=0, this means that the basic instruction is removed. If K=1, this means that the basic instruction is converted into a single output instruction. If K>1, this means that the basic instruction is converted into one or more output instructions. This implementation will now be discussed using an example. An example will be discussed with reference to Fig.6, where the route 60 is depicted from the point And the origin to point B destination in Amsterdam. Route 80 from A to B is calculated by module 41 calculate the route and sent to the module 42 instructions as a set of data that describes the vectors roads and coordinates. Module 42 instructions will use the dataset to create a set of basic instructions. In this example, the set of basic instructions might look like this:

- START

20 m to the RIGHT

300 m TURN

- 230 m to the RIGHT

- 900 meters to the LEFT

- 150 m to the RIGHT

- 55 m-RIGHT

- 75 m FINISH

STOP.

This set b is basic instructions 51 is removed from route 80 and cartographic data and contains no statement of the person, but more a short form description of route 80. Translator 48 "profile statement" translates basic instructions output instructions, see arrow 57 in figure 4. To translate (i.e. convert) basic instructions, possible instructions to the person stored in the database 70 data, combined with basic instructions. In this example, the output statement is generated by the translator 48 "profile statement" over time and limited by separating direction from the distance that must be overcome are, at least, the following:

- turn right;

- make a turn;

- turn right;

- turn left;

- turn right;

- turn right;

- the destination is reached.

As can be seen in the upper part 6, route 80 immediately bends to the right without crossing. The driver can be daunting when there is no guidance for this turn. However, the navigation device 10 may not issue an output instruction for these "normal rotation"as they exist in the basic instructions like "turn right" and "turn left". Also these rotations can be specified (K>1) depending on the profile of drivers. Additional (i.e., K>1) instructions can be issued to drivers with, for example, a profile in which Italia with low aggressiveness. As these drivers love to drive safely and will probably want to get as many instructions as possible. Also, it is the driver that has a relatively high age (e.g. age >60), or drivers who like to avoid the risks (drivers, which can be classified as "calm" drivers). In this example, the output statement can look like this:

- (now) turn right;

- (turn right here, follow the road);

- (turn to the right again, just follow the road);

- after 200 metres take the turn (then at the end of the road turn right);

- (now) make a u-turn (then at the end of the road turn right);

at the end of the road turn right and then get in the left lane);

- (now) turn right (then stay in the left lane);

- (front left);

- after 200 metres turn left, then turn right;

- turn left (turn right);

- turn right (turn right);

- turn right (then you have arrived at the destination);

- you have arrived at your destination.

The above text between the brackets is given to the driver, which has a large value of the parameter "percentage of congresses, ignored by the driver or a large value for p is acent turns, where the driver turned to the right instead of turning left or Vice versa."

You can insert additional instructions (K>1) for the driver who has even a higher value of the parameter "percentage of congresses, ignored by the driver, or even a higher value for the percentage of turns, where the driver turned to the right instead of turning left or Vice versa" in his driving profile:

(you should) turn right (here).

Additional instructions for drivers that seem confusing left and right turn, which indicated high (e.g., >80) the value of the parameter "percentage of turns, where the driver turned to the right instead of turning left or Vice versa is:

- in Europe: turn right (this is a sharp turn);

in the UK: turn right (it is a gentle rotation);

- in Europe: turn left (it is a gentle rotation);

in the UK: turn left (this is a sharp turn).
