The technical field to which the invention relates.

The present invention relates to a control device for a vehicle and to a method of assisting a driver of a vehicle when Parking in accordance with the independent claims.

The level of technology

From the publication DE 102005023177 A1 known way driver assistance, providing registered by sensors of the environment around the vehicle. This situation near the vehicle cause the specified end position of the vehicle. Then in the resulting image conditions specified end position of the vehicle can be moved or rotated by the input device.

Disclosure of inventions

Proposed in the invention, the control device described in the corresponding independent claim of the invention has, compared with the known solution, the advantage that help the driver to automate Parking is provided and without measuring sensors Parking space. With the ability to manually enter at least one border of a Parking space the establishment of the position of the Parking space is possible without gathering information about it using the sensors. Further, due to the fact that manually entered the boundaries of the Parking space is correlated with the appropriate tools with the current position of the vehicle, can be calculated path of movement of the vehicle from its current (actual) position to a Parking space within a Parking space. This allows you to develop a way to help the driver of the vehicle when Parking, do not involve the use of distance measuring devices for measuring a Parking space. Further, for example, by entering the observed ahead of the boundaries of the Parking space using the appropriate tools help the driver when Parking can be provided for Parking spaces by which the vehicle has not yet passed for measuring a Parking space.

Corresponding advantages are achieved in the implementation proposed in the invention of a way to help the driver of the vehicle when Parking.

The activities outlined in the dependent claims describe private and preferred embodiments of the control device and method of assistance when Parking. So, it is advisable to register the beginning of a Parking space when exposed to the instrument input. This allows very easy to enter the boundaries of the Parking space, allowing to enter the boundaries of the Parking space just a single exposure to the instrument input, for example the EP pressed the button.

It is also advisable to provide a measuring device for collecting information about the movement of the vehicle after determining the beginning of a Parking space. This allows measuring the movement of the vehicle along the Parking space, to measure the length of Parking spaces. If the vehicle has reached the next place, in which, for example, you enter a different boundary of the Parking space based on the stored distance you can judge the length of a Parking space without during such movement of the vehicle to direct the "feeling" of Parking space sensors for measuring dimensions of a Parking space.

Further, proposed in the invention, the control unit it is advisable to combine with the input device having means for establishing a ratio between the boundary of the Parking space and the position of the vehicle. This allows you to get a portable computing device that you can carry in the vehicle and which can serve as a Parking assistant, used for Parking assistance also on vehicles not equipped with sensors distance.

Furthermore, such portable computing device, it is expedient to equip si is the subject of positioning to collect information about the movement of the vehicle. Thanks to the determination of the motion of the vehicle may be, for example, and in the absence of connection with the electronic equipment of the vehicle, for example with speed sensor wheel to measure distance traveled.

It is also advisable to provide portable computing device display to show the position of the vehicle relative to the beginning of the Parking space. This enables a user to control the display the correct input in the beginning of the Parking space, for example by controlling the alignment mark with the beginning of the Parking space. It is also appropriate to provide for the possibility of correction entered the Parking space, for example, by moving the marker on the image of the Parking space.

In addition, the portable computing device, it is expedient to equip the navigation device to calculate the route to the entered destination. This allows, in particular, to calculate the route to the Parking lot (Parking). In this case, the portable computing device can not only throw a route to a Parking lot, but to help the driver of the vehicle in the Parking lot.

It is also advisable option which will display aema on the display mark is first combined with the boundary of the Parking space, then by the influence of the input tool introduces the beginning of a Parking space. This allows a simple way to determine the length of a Parking space by entering the start and end of a Parking space. Next, at a known ratio obtained by computing the projection of the mark on the environment around the vehicle and the position of the vehicle can also directly correlate the beginning of the Parking space with the current position of the vehicle. The fact that the position of the markers is known, and if it is at a certain position of the vehicle is combined with a mark, which the driver sees on the display, then on the known relationship between the position of the mark and the position of the vehicle is possible by calculation to determine where the position relative to the vehicle is the beginning of a Parking space, introduced by the influence of the input tool.

The control device 3 includes, in turn, the computing unit 4, which serves to calculate the length of a Parking space and calculating the motion path at the entrance to a Parking space. To the control device 3 is connected to the controller 5 controls with controls such as buttons 6. In the storage device 7 recorded data, in particular the size of the vehicle, to the which are used to calculate the motion path to the Parking space, are detected and measured in a Parking space. In addition, the stored data of the vehicle are used to determine the suitability of a particular Parking space for Parking. In yet another embodiment of the invention for the application of the portable computing device on a range of vehicles in the storage device 7 to store the sizes of various types of vehicles.

The measurement of the movement of the vehicle, or gathering information about this movement may be effected in any way. In the first embodiment of the invention, the control device 3 has an inertial sensor 8, in which the acceleration sensor measures the acceleration of the portable computing device 2, and thus the vehicle 1. On the basis of the received signal acceleration by integration it is possible to determine the movement of the vehicle in the direction of the corresponding coordinate axis. In yet another embodiment of the invention, in addition to the inertial sensor, or instead, it is also possible to provide a device 9 for determining a location using radio signals, such as GPS locator (device positioning system the global positioning system (GPS)to determine the current Polo is placed the vehicle on the basis of the difference between the recorded positions of the vehicle to determine the movement of the vehicle. In yet another embodiment, the invention also may provide an interface 10 mates with the sensor 11 of the speed of rotation of the wheel, determining, for example, the rotation of the wheels 12 of the vehicle 12. In yet another embodiment, the invention also may provide an interface 14 mates with the sensor 13 of the rotation angle of the steering wheel, providing the definition of the current rotation angle of the steering wheel.

Instructions for maneuvering may be issued to the driver, for example, by acoustic means (in the form of audio information) and/or optical means (in the form of visual information). To this end, in the vehicle provided by, for example, a speaker 15 and a display 16. Thus, the driver can be submitted commands to turn the steering wheel to the left, turn the wheel to the right, move forward or move back. In yet another embodiment, the invention may provide an interface 17 for the automatic execution of the control operation of the vehicle. Through the interface 17, for example, can operate the steering device 18 of the vehicle with which the automation affects the angle of rotation of the guide wheels of the vehicle and thereby enables automatic movement of the vehicle with taxiing on the calculated phase the path to the Parking space in a Parking space.

For a visual representation of the environment around the vehicle can be provided by the camera 19, the recording environment around the vehicle. Images of the environment around the vehicle, if necessary, can be transmitted directly from the camera 19 on the display 16. In yet another embodiment of the invention, the computing unit 4 unit 3 control may be applied to captured by the camera 19, the image of the mark to display on the display 16.

In yet another embodiment of the invention a portable computing device 2 may be performed so that the computing unit 4, accessing data stored in the storage device 7 in the form of digital maps, and using the device 9 location, defined the route from the current position of the vehicle to the destination, for example to the Parking lot.

An example implementation of Parking in a Parking space, stretched along the edge 20 of the roadway, are presented in figure 2. In yet another embodiment of the invention, not shown, Parking can accordingly be carried out in Parking space, located towards the edge 20 of the roadway in any other way, for example across the roadway.

On firgt tool 21 shown in the initial position. The path of movement of the vehicle 21 from its original position 23 Parking in the Parking space 24 is depicted with reference to the center of the rear axle of the vehicle. In figure 1 the position number 25 marked the appropriate place on the rear axle 26 of the vehicle 1.

Shown in figure 2 situation, the driver of the vehicle 21 has detected a potential Parking space 24, which is located in front of the vehicle 21 along the edge 20 of the roadway and passes between the first barrier 27 and another obstacle 28 arranged in front of it along the edge of the roadway, in the form of a so-called Parking niches. The driver selects on its assessment of the distance 31 from your vehicle 21 to the first element 27 and moves about straight forward about keeping this lateral distance to the first obstacle. This is the first distance 31 is selected by the driver, based on its own estimates, and is, for example, about one meter. The driver takes the vehicle from the initial position 30 forward until until in position 32 of the alignment he would not see that the vehicle 21 that right exterior mirror 33 rear view caught up with the front corner of the first obstacle, and thus with the beginning of the Parking space 24. This position is in the advanced alignment presented in figure 2 with a dashed line 34. Enter the beginning of the Parking space and the end of the Parking space can be aligned with the boundary of the Parking space outside rearview mirrors, but after appropriate fixation of the alignment - any other part of the vehicle such as the front bumper.

Now, the driver creates a control on the remote control 5 control, for example, by pressing the set button 6. Computing unit 4 captures the impact on the appropriate tool input as the registration of the beginning of the Parking space 24. Because the driver was set to approximately withstand distance 31 computing unit 4 on the basis of this approximate distances and enter the boundaries of the Parking space when the alignment of the external rear view mirrors with the front edge of the first element 27 can establish a relation between the current position 32 of the vehicle 21 and the beginning of the Parking space 24, marked by a dotted line 34. Then the driver takes the vehicle straight ahead, along the shown in the drawing section 22 of the road until you reach the second position 35 of the alignment. In this second position defining a Parking space the vehicle is aligned with its outer mirror 33 rear view beginning on the natives obstacles 28, i.e. the opposite of the beginning of the Parking space 24 or - when viewed from the first element 27 with the end of this Parking space. Here the driver again affects the tool 5 control. Computing unit 4, requesting means for determining the segment of the path relevant information, determines the distance between the first position 32 and the second alignment regulation 35 of the alignment. This process can be carried out, for example, by querying the sensor 11 speed wheels, inertial sensor 8 or GPS locator 9. In yet another embodiment of the invention involving sensor 13 of the rotation angle of the steering wheel or by tracking the movement of a vehicle along a curved path by querying the GPS locator 9 or inertial sensor 8 can also be determined deviation of the vehicle from a straight-line section of the route, so when determining the length of the Parking space 24, if necessary, can be taken into account by appropriate calculations, the angularity of the path of the vehicle 21 between the first position 32 and the second alignment regulation 35 of the alignment.

Further, the distance between positions 32, 35 alignment compared to the one stored in the storage device 7, the size of the mi of the vehicle, in particular its length. If the computing unit 4 determines that the length of the Parking space 24 is sufficient for Parking, he calculates, starting from the second position determining Parking space (alignment position) or if the driver drove a little forward from the current position of the vehicle, the path of movement to a designated 23 Parking in the Parking space 24 with regard to the front and rear boundaries of the Parking space. A possible path of movement shown in figure 2 and includes a first area of supply of the vehicle forward to a point 36 changing the direction of movement of the switch point for reversing), the first portion 37 of the movement on the arc of a circle or clothoid with turned to the right the wheel to the point 38 of the rudder and the second section 39 of the movement on the arc of a circle or clothoid with turned in the opposite direction the wheel.

Now, in the first variant of the invention, the computing unit 4 initiates the issuance of the driver instructions on maneuvering, such as issuing instructions first to reach the vehicle forward until the point 36 changing the direction of motion, and then move back in, turning the steering wheel, respectively, until the vehicle reaches the end position 40 on the 23 Parking spaces within the Parking issue is space 24. Issuing instructions on maneuvering can be done using audio information through the speaker 15 or by using optical command signals on the display 16.

In another embodiment of the invention, the driver may be issued specifying only with regard to the supply of the vehicle forward and backward, and turning the steering wheel automatically. For this purpose, the control device 3 via the interface 17 actuates the steering device 18 of the vehicle, providing automatic taxiing from point 36 changing the direction of movement to the end position 40.

In yet another embodiment of the invention the determination of the beginning and end of a Parking space can also be accessed by using the camera 19 and the display 16 of the vehicle. The example displayed on the display 16 of the image 50 shown in figure 3. The camera 19 is directed to a region located on the right front of the vehicle 21, and on the displayed image 50 shows the first obstacle 27 and the second barrier 28. The camera 19 is oriented in this way, to visualize, in particular, the surface 51 of the edge 20 of the roadway. Further, in the display image 50 is displayed mark 52. Mark 52 is made, for example, in the form of crosshairs. When the driver takes the vehicle fixing the arrow 53, mark 52 is moved along the first obstacle 27 to putting on the displayed image 50 with the front border of the first obstacle 27. In this embodiment, the invention marked by a dotted line 54 position of the middle line 55 mark 52 is combined at the base 56 of the first obstacles with a visible border on the first obstacle. The user can now specify the impact on the tool 6 input that mark 52 is aligned with the beginning of the Parking space, located between the first barrier 27 and the second barrier 28. When this mark is focused on a point basis, in which the front left edge of the obstacles encountered with the surface of the roadway. If the vehicle has reached a position in which fixed-mounted camera is directed at this point, and if visible to the observer mark is aligned with this point, when the known dimensions of the vehicle and the known position of the camera on the vehicle, the position of the specified point relative to the camera, and hence relative to the vehicle, is uniquely defined. Now, after the user enters a control computing unit 4 can relate this point to the current position of the vehicle. For example, you may be inside the mausoleum is on the map of the environment around the vehicle, on this first point will mark the beginning of the coordinate system.

If now the vehicle will travel further in the direction of the arrow 53, when the alignment mark with the back edge of the second obstacle 28 can be made the input of another control. Tracking the movement of a vehicle from the beginning to the end of the Parking space can be calculated by appropriate calculations, as the length of the Parking space, and its position relative to the current position of the vehicle. In principle, through the appropriate calculations built a kind of map of the environment, which is applied to the position of the beginning of the Parking space and the position of the end of the Parking space, as well as the current position of the vehicle. Next, the calculated accordingly map the environment, using appropriate calculations to display depicting this situation, for example, according to the image of the vehicle 21 and barriers 27 and 28. It is reasonable that the driver was given the opportunity, if necessary, to correct the position of the vehicle 21 in accordance with their vision of the situation by entering the relevant managing impacts.

In another in which the version of the invention the marker 52, displayed on the displayed image can be moved, in particular in the horizontal direction to lock the stamp is really at the base of the first obstacle 27. This allows, for example, to compensate for the inaccuracies associated with the arrival of the driver past the first obstacle 27 on the distance to the last, other than that specified. In yet another embodiment of the invention, the marker may be performed, as shown in figure 3, with the side markers in the form of additional crosshairs. If the basis of the first element 27 is aligned, for example, is not an average or left cross, right cross, then the user can respectively enter information about the compliance of this crossing with the base of the obstacles. Then, based on the position of the mark or select one of the crosshairs, you can judge the distance from the vehicle 21 to obstacles, and hence to the border of the Parking space, the designated roadway.

Instead of the point base to uniquely determine the position can also be used, for example, the relative positioning of the bumper because the bumper in most cases are about the same height, which also allows you to set unambiguous spatial relationship.

The camera 19 in one embodiment, about what westline of the invention can be installed with the orientation angle of 90º to the direction of movement of the vehicle directly. However, in the embodiment of the invention shown in figure 3, the camera is oriented in such a way that it looks almost ahead of the vehicle. This allows you to enter the beginning and end of a Parking space, even if the vehicle has not yet reached a Parking space or incompletely passed him.

If there is only one obstacle, which is necessary to Park the vehicle, the control device can help the driver and in the case of Parking before that the only obstacle. In this case, simply enter the boundary, for example, the first obstacle 27, if the barrier 28 is missing. Then, the user accordingly enters the control, indicating his desire to Park in front of the obstacle.

In yet another embodiment of the invention the process of Parking along the path of movement according to the image in figure 2 may be displayed in an animated view.

Further, if the movement of the vehicle from the first point 32 enter the vehicle before it reached the second point 35 input passed part of the path, the length of which would be enough for Parking, the driver may be issued indicating that it has a sufficiently large Parking space. After e the CSOs, the driver can proceed to the Parking lot before measuring just a Parking space.

When using a portable computing device user when first using this device in your vehicle must provide the computing device with the data necessary to calculate the trajectory of caroliana vehicle to the desired Parking space and to calculate the suitability of the Parking space. To enter you must, for example, the length of the vehicle width of the vehicle, its wheelbase and turning radius. If the control unit is already built into the vehicle, this data is typically entered by the manufacturer.

The implementation proposed in the invention of the method begins in step 60 initialization, in which the driver by using the remote control 5 control reports its desire to Park at all. At step 60 the initialization can also be asked about whether the user wants to Park parallel to the direction of movement of the vehicle or transversely of the direction of movement of the vehicle. The intention of the driver is used for subsequent calculation of the Parking lot and considering the length of the Parking space. In this case, the user will have to decide for yourself only then, will there be enough Parking depth of the Parking space.

By following the initialization of p is ditch the validation step checks in was whether the impact on the governing body, for example, was pressed if the button 6, to indicate the start of a Parking space. If this hasn't happened, then back to the first test step 61. If there is control on the remote control 5 control, then on the first installation step 62 is the beginning of a Parking space. Triggers the calculation of the path traveled by the vehicle from its current position, so that, starting from a fixed start position of the Parking space, gathers information on the traversed path. Then it moves to the second verification step 63. On the second testing step 63 is performed to check was whether the controller 5 controls repeated exposure to specify the end of a Parking space, for example, by pressing button 6. If not, then back to the second verification step 63. If Yes, then on the first computing step 64 calculates the length of a Parking space between the set start and set end of the Parking space. This is used, for example, the difference of the provisions of the encoder or the difference between the positions defined by the locator (the device location. Then you go to the third test is the step 65, which clarified the length of the Parking space is compared with the length of the vehicle. If the length of the vehicle plus an additional distance for maneuvering exceeds clarified the length of the Parking space, for example, one meter, this Parking space is considered as unsuitable for Parking, and the process ends in the next step 66 the end. The user is presented with relevant information. If a Parking space is large, and therefore, suitable for Parking, the driver can be acoustic and/or optical means. Automatically or at the command of the driver is the transition from the third test step 65 on computational step 67. This computational step 67 is calculated path of movement of the vehicle from its current position to a suitable Parking space within a Parking space. Then at step 68 the issuance of instructions are issued to the driver of a vehicle instructions on maneuvering to caroliana in a Parking space or Parking lot is performed at least partially automatically. When reaching the end position 40 within the Parking space, the process ends at step 69 the end.
