The invention relates to techniques for the protection of vehicles against unauthorized use and designed to counter the attempts of theft.

Currently in the patent and technical literature is a wide variety of alarm system TC (SDTS), indicating unauthorized access to protected vehicle. The General principles and requirements STSTS fixed by the ECE Regulations No. 97, enacted in the territory of the Russian Federation from January, 2000 (GOST R 41.97-99).

To STSTS applies, in particular, automotive anti-theft device according to the US patent No. 4777468, 60 R 25/00, containing generators and selective frequency filter connected via a cable to the onboard network, sensors unauthorized use of the vehicle, the outputs of which are connected to the trigger inputs of the generators, the site of the alarm system, a control input connected to the output of the above-mentioned filter.

The principal disadvantage of such devices is that they are intended only for ″scare″ random thieves, not to protect vehicle against theft.

Anti-theft provide anti-theft device with the prohibition of starting the engine of the vehicle. An example of such device is the anti-theft device according to patent SU # 1544613, 60 R 25/4, containing connected via a cable to the onboard network, the Central control unit, sensors for unauthorized use of vehicle, the nodes of the alarm system and components blocking the functional bodies of the CU, the node set associated with the trigger input of the Central control unit, a signal input which is connected to the outputs of the sensors and nodes blocking of the functional bodies of the CU, and outputs - control inputs of sensors, nodes and alarm units blocking the functional bodies of the vehicle.

The disadvantage of this and similar devices is the ability to identify hosts blocking of the functional bodies of the CU to replace them and the subsequent theft of the vehicle. Nodes blocking of the functional bodies of the CU, as a rule, are identified visually by the presence of the connected redundant wires. Masking redundant wires (by combining groups of wires in the cable, similar to single wire) does not cause hijacker special difficulties: cables, replacing a few wires, can be easily determined by thickness. That is, such anti-theft device protects vehicle from inexperienced thieves. An experienced professional can steal a vehicle in 3-4 minutes after the beginning visual inspection of the storm.

From this lack of free anti-theft system for vehicles according to the patent RU is 2090395, 60 R 25/00 containing the processing unit processing the incoming information and synthesis teams, the first input of which is connected to the power bus through the ignition switch and the first output and the second input is connected with the ability to request and read code unlock, respectively, the input and output of the node set, which includes the associated radio channel electronic "tag" and the receiver, the second output processor unit processing the incoming information and synthesis commands through the communication channel connected to the input nodes of the blocking of the functional bodies of the CU, each of which has an connected contact groups to the functional body of the TC relay and consistently included the block matching with the communication channel and the decoder, and the input voltage of each node blocking of the functional bodies of the CU is connected to the first input of the processing unit processing the incoming information and synthesis commands.

In this device, the hijacker is not able to visually identify nodes blocking of the functional bodies of the CU (with a view to their replacement and the subsequent theft of the vehicle). However, a simple "continuity test" contacts when the on and off ignition allows the hijacker to separate nodes blocking of the functional bodies of the CU from the node management functional bodies. Of course, time on the circuit or disconnection of the relay contacts when switching on and switching off ignition you need significantly more than visual identification. But theft, however, remains possible.

To reduce the likelihood of theft of the vehicle by minimizing the possibilities of both visual and electric sites are identified block of the functional bodies of the CU, RU patent NO. 2160196, 60 R 25/00, selected as a prototype of the present invention, the following combination of elements: the processing unit is processing incoming information and synthesis teams, the first input of which is connected to the power bus through the ignition switch and the first output and the second input is connected with the ability to request and read code unlock, respectively, the input and output of the node set, which includes the associated radio channel electronic "tag" and the receiver, the second output processor unit processing the incoming information and synthesis commands through the communication channel connected to the input nodes of the blocking of the functional bodies of the CU, each of which has a relay contact connected groups to the functional body of the vehicle, and has consistently enabled block coordination with the communication channel and the decoder, and the input voltage of each node blocking of the functional bodies of the CU is connected to the first input of the processing unit processing the incoming information and synthesis teams, while at least one is n site blocking functional bodies TC introduced delay element and the motion sensor, and in each node blocking functional bodies TC - memory element and the first input of the memory element is connected to the output of the decoder, a second input coupled to the output of the motion sensor, a third input through a delay element connected to the first input processing unit processing the incoming information and synthesis commands, and the output connected to the control input of the relay.

Blocking of the functional bodies of the CU is carried out only when the movement of the vehicle. Therefore, standing on the place of the vehicle when the ignition is in the node block functional bodies TC is the closure of normally open relay contacts or open the normally closed contacts. This means that the thief will not be able by "continuity" find and replace nodes blocking of the functional bodies of the vehicle.

However, we cannot exclude the possibility of criminal conspiracy hijacker and employee service center or employee of the service station. As practice shows, this scenario is quite possible. With this arrangement the employee service center establishes a secret link in the chain blocking the functional body of the vehicle, preventing the possibility of blocking the vehicle in case of theft. To the TS user (i.e. the owner of the vehicle or his authorized representative, such as a driver or a family member) would not have found found on the cross line is, do it with a hidden toggle switch in open condition when the normally open contacts of the relay or closed while the normally closed contacts of the relay.

About the location specified toggle the employee service center tells the hijacker, resulting in he gets a chance at a convenient time for you to neutralize each node of the functional block of the body. The user, exploiting their vehicle, can not guess about the existence of the specified jumper, because it is hidden from his eyes and open (closed) set the toggle switch. Hijacker, seizing the opportune moment, can short-circuit (open) jumper the switch and to carry out theft of the vehicle. It is a disadvantage of the above devices.

The object of this invention is the anti-theft system for a vehicle containing a processing unit, a control input through which the ignition switch and the power bus is connected to the power source, the remote user identification, consisting of related radio portable part and the portable part, associated with the processor unit, a display unit, the input of which is connected to the output processing unit, and the nodes of the functional block body, each of which contains serially connected first block matching, the input is done using a communication channel connected to the processor unit, and decoder, and a memory element, the inputs of which are connected, respectively, to the outputs of the decoder delay elements and motion sensor, and a first output connected with the control input of the relay, the contacts of the respective contact groups which are connected to the blocked functional body, and the input of the delay element is connected to the input voltage node of the functional block of the body and connected to the control input of the processor unit in each node blocking function body is entered serially connected unit testing of the contact groups, made with the possibility of indicating the presence of jumpers in the contact group relay, non-volatile memory, the encoder and the second block matching whose output is connected to the communication channel, and control inputs of the testing unit of the contact groups and the non-volatile memory are connected, respectively, with the first and second outputs of the memory element, and the unit test pin group connected to the respective contact groups of the relay, and a display unit configured to receive from the processing unit signals the indication of the jumpers in the contact group relay.

Private significant features of the invention are as follows.

To perform the communication channel can be used following the Alt ERN options.

The communication channel can be made wireless, such as radio communication format Bluetooth.

The communication channel can be made conductive and, in particular, to provide a multiplex bus communication, for example CAN-bus.

As a communication channel can be used on-Board power the vehicle.

As unit testing contact group is measuring the resistance of the circuit.

The present invention is the creation of the anti-theft system for vehicles, with a higher than device-prototype, likely to protect the vehicle from theft.

Provide technical result is the ability to timely alert the user of TC in TC secretly installed in collusion with the hijacker circuits functional block bodies additional elements such as lintels, preventing actuation of the blocking of these sites at the time of theft.

The essence of the invention is illustrated by drawings.

Figure 1 shows the structural diagram of the proposed anti-theft system for a vehicle.

Figure 2 presents a structural diagram of part of the proposed anti-theft system for the TC - node blocking function body.

The presented structural diagrams the following notation is used: 1 - wear part; 2 - BC is to the remote user identification; 3 - take part; 4 - processor unit; 5 - channel; 6 - node functional block body; 7 - power supply; 8 - power bus; 9 - ignition switch; 10 - bus ignition key; 11 - delay element; 12 - the first block matching; 13 - decoder; 14 - a memory element; 15 - relay; 16 motion sensor; 17 - jumper; 18 - unit testing contact groups; 19 - volatile memory; 20 - coder; 21 - second unit coordination; 22 - the display unit.

It should be noted that the structural scheme of the anti-theft system for a vehicle shown in figure 1, contains only those elements that are necessary to explain the essence of the proposed technical solutions. Real anti-theft system for vehicles must have a number of elements, not shown in figure 1, in particular blockers doors, the nodes of the call user or protection authorities about theft, etc. on the other hand, the functions of certain elements, such as a display unit, must be significantly wider than those described in this application. However, this does not relate to the subject matter of the invention, therefore, in this application will not be considered.

The proposed anti-theft system for a vehicle includes the processing unit 4, similar to the processor unit of the information processing and synthesis commands in the device prototype. The control input processing unit 4 via the bus 10 of the ignition key and through the distribution Board 9 plugs connected to the bus 8 power connected to the onboard source 7 power supply such as a battery. The composition of the anti-theft system for a vehicle includes a block 2 remote user identification, consisting of related radio wearable parts 1 and transportable part 3 associated with the processor unit 4, connected to the block 22 of the display. In addition, the structure of the considered system is composed of nodes 6 functional block body (to simplify the figure 1 shows only one such node).

Each of the nodes 6 functional block body includes serially connected first block 12 of the agreement, the entrance of which by means of the channel 5 is connected to the processor unit 4, the decoder 13, the memory element 14 and the switch 15 connected to the corresponding contact group to be blocked functional body, as well as the delay element 11 and the motion sensor 16, the outputs are connected to respective inputs of the memory element 14. While the input of the delay element 11 and the input voltage of node 6 functional block body connected to the bus 10 of the ignition key (a special connection supply voltage to the node 6 functional block body on figure 1 and figure 2 are not shown). The contact group of the relay 15 is connected to the blocked functional body.

Diagram of the memory element 14, shown in figure 2, contains a D-flip-flop 14.1 with the trigger on the leading edge of the clock pulse, two-element AND-NOT 14.2 and amplifier 14.3. Diagram of the memory element 14 is completely analogous to the circuit shown in the patent-prototype (RU # 2160196, 60 R 25/00), except that in the patent prototype was used, only the first output element 14 of the memory.

Some parts of the site 6 functional block body require initial setup. However, the formation and signal connections initial setup in node 6 block functional body of the obvious and to simplify figure 2 is not shown.

Feature node 6 functional block body in the present anti-theft system for vehicles is the availability of the circuit test that contains one United block 18 test contact groups, non-volatile memory 19, the encoder 20 and the second block 21 approval, the output of which is connected to the communication channel 5. The input unit 18 test pin group connected to the contacts of the corresponding relay contacts 15. The block 18 testing of contacts made with the possibility of indicating the presence of jumpers in the contact group of the relay 15.

In circuit testing introduced an additional control circuit. The first output of the memory element 14 (the output of the amplifier 14.3) connected to the control unit 18 test contact groups and to the control input (i.e. to the winding) relay 15, and the Torah output (direct output of D-flip-flop 14.1) - to the control input of the nonvolatile memory 19.

Unit 22 of the display is configured to receive from the processor unit 4 signals indicating the presence in the circuit of the functional block body hidden jumper 17. For definiteness, in this application shall be considered normally open relay 15, to which the block 18 testing contact group checks the jumper 17, which are parallel to the contact group relay 15 (as shown in figure 1).

The composition processing unit 4 may include, for example: the driver signals the request for unit 2 remote user identification, the demodulator of the signals coming from this node, the node checks and compliance identification code matching node with the communication channel 5, etc.

Scheme for the construction of unit 2 of the remote user identification is determined by the specific form used in its composition wearable part 1.

When performing a wearable part 1 in the form of active key FOB supplied with a power source of the portable part 3 should include the driver signals of the request. Wearable part 1 must be provided with a node forming an identification code for transmission over the air transportable in part 3.

When performing a wearable part 1 in the form of passive key FOB, sabien the th antenna for receiving signals, a pumping frequency, as well as a host of forming an identification code for transmission over the air transportable in part 3 unit 2 remote user authentication. The specified transport part 3, in turn, in addition to the schemes of receiving the identification code, must include a generator pumping.

Different ways to build a wearable part 1 unit 2 remote user identification series-produced-by the applicant, represented, for example, in the Directory "Automotive security systems", Moscow, Altonika, 2003.

Channel 5 connection can be either a channel or a transmission channel frequency-modulated signals by wire, food or General multiplex bus data exchange (for example, a CAN bus). The type of communication channel 5 is uniquely determined by the specific electric diagram included in the processing unit 4 and the composition of the nodes 6 functional block body matching units intended for matching on input and/or output communication channel 5. And the radio channel, and the channel transmission over the wires of the power supply (or CAN-bus) is widely described in the patent and technical literature, for example in the description of the patent RU № 2090395, 60 R 25/00, previously received by the company by the applicant.

Examples of the functional bodies, which can be connected relay contacts 15 that contain what about the part of the node 6 functional block body, could be fuel pump, oil line and other

The motion sensor 16 is a standard node of the electrical equipment of the vehicle. It detects the presence of movement of the vehicle and generates at its output an enable signal only when the movement of the vehicle. When the technical implementation of the inventive anti-theft system for vehicles as sensor 16 motion was used a standard chip ADXL202 manufactured by Analog Devices, Inc. (USA).

Other blocks and items included in the inventive anti-theft system for vehicles, are standard, widely described in the technical literature and in particular the explanations do not need.

The design of the unit 6 block functional body must match the design of the standard control units functional bodies of the vehicle (for example, a standard automotive relay). While the delay element 11 and 16 gauge movement that does not require for its execution cabinets with large dimensions and weight, may be included in node 6 functional block body.

The proposed anti-theft system for vehicles is as follows.

In order to be able to use TC, each user must be strictly defined wearable part 1 unit 2 remote user identification (in the form of an electronic "tag" - the key FOB, tra is of spondere etc). Wearable part 1 by signals carried by part 3 unit 2 remote user identification broadcasts a special unlock code. This code is received and demodulated in the transportable part 3 unit 2 remote identification of the user and transmitted to the processing unit 4 for processing and synthesis of relevant commands. The signals carried by part 3 unit 2 remote user authentication, causing the issuance of its wearable part 1 special unlock code that is generated from the query processing unit 4. After a special unlock code is entered in the processing unit 4, in the latter compares received a special code with a valid unlock codes (in the General case there may be a set of valid codes corresponding to different users of the TS, each of which has its own wearable part 1 with unique special code unlock). The coincidence of the received specific code to unlock with one of the valid codes, the processing unit 4 generates the communication channel 5 local unlock code (in the General case, other than a special code to unlock a wearable part 1).

As channel 5 links may be used, or the radio channel wireless communications (e.g., a Bluetooth channel, or data channel is about power wires or General multiplex bus communication (for example, on the CAN-bus) with the use of frequency-modulated signals.

The composition of the anti-theft system for a vehicle includes at least one node 6 block functional organ installed instead of standard site control any of the functional bodies of the CU. The essence of the work site 6 functional block body is that after identification of the user to repeat the work replaced them with a control node, and in the absence of identification of the user to interfere with the normal function of the body. In the application considered, for simplicity, only the case when the control node, which is replaced by node 6 functional block body is a motor relay (for definiteness - normally open). Thus, in order to steal a vehicle, the hijacker is enough to determine all the nodes 6 functional block body and replace them with the corresponding control nodes (in this application is to replace the standard automotive relay).

However, the appearance of the node 6 functional block body repeats the form of the corresponding node. In appearance to identify nodes 6 functional block body is impossible.

Whatever the communication channel 5 would not be connected to the node 6 functional block body (radio be the wired connection, the communication channel for on-Board power supply or even CAN-bus), to detect the nodes 6 functional block body by the presence of "extra" plug wires impossible. Any "extra" wires simply no.

However, the hijacker can either try to identify the nodes 6 functional block body by the method of electrical continuity when turned on and turned off the ignition, or to negotiate with the employee service center, conducting vehicle maintenance, installing in vehicle hidden jumpers 17 with toggle switches, a circuit which will enable the functional bodies, switchable nodes 6 functional block body.

In order to prevent such actions hijacker, node 6 functional block body entered the circuit test, consisting of serially connected unit 18 test contact groups, non-volatile memory 19, the encoder 20 and the second unit 21 approval, the output of which is connected to the communication channel 5 for the transmission of data in the processing unit 4.

Common to all nodes 6 functional block body is that power them comes from a source 7 power supply, such as a car battery, bus-8 power and then after closure of the switch 9 of the ignition when the ignition is on bus 10 key sage the project.

Since the tire 10, the ignition key is connected with the control input of the processing unit 4, the circuit breaker 9 ignition means for the processing unit 4, the flow control signal. On this signal, the processor unit 4 by the formation of the query wearable part 1. This means that after a short pause after closure of the ignition switch 9, the communication channel 5 enters the local unlock code (unless, of course, the circuit breaker 9 ignition was carried out by the TS user with a wearable part 1).

When power is supplied to the node 6 functional block body in this site is supplied in each incoming element. In addition, power is supplied to the input of the delay element 11. The length of the delay (in this case the duration remains unchanged zero signal at the output of the delay element 11 after ignition) is chosen such that the local unlock code has managed to go through the chain of the communication channel 5, the first block 12 of the agreement, the decoder 13" and would lead to the triggering of the decoder 13 in the case, if the local unlock code coincides with the stored decoder 13 local reference code unlock. That is, if the ignition switch 9 is closed by the user, the delay time of the delay element 11, the user of vehicle opasne the Xia (the presence of a wearable part 1) and the decoder 13 generates at its output an enable signal, served in item 14 of the memory.

When the power is turned on (i.e., with the closure of the ignition switch 9) in the memory element 14 D-trigger 14.1 set to the zero state (chain and shapers initial setup of figure 2 not shown). This status cannot be changed until the end of time interval delay of the delay element 11. At the end of the time interval delay for D-flip-flop 14.1 passes the leading edge of the clock signal, on which the D-flip-flop 14.1 logged output signal from the decoder 13. If the user is not identified (i.e., driving a vehicle is the hijacker), then the output of the decoder 13. there is no single signal, and the output signals of the D-flip-flop 14.1 remain unchanged:

signal of the logic zero to direct the output of D-flip-flop 14.1 prohibits the extradition of signals nonvolatile memory 19;

signal logic unit at the inverted output of D-flip-flop 14.1 causes the output element AND IS NOT 14.2 (and hence at the output of the amplifier 14.3) produces a signal representing the inverted output signal of the sensor 16 movement.

That is, when driving a vehicle hijacker signal to the relay coil 15 (the first output signal of the memory element 14, is taken from the output of the amplifier 14.3) depends on moving vehicle or standing still. If the vehicle is standing still, then the relay coil 15 a permissive signal is received. In this case the e operation of the relay 15 coincides with that of a conventional normally open motor relay: when the ignition relay 15 is opened (at the output of the amplifier 14.3 in the absence of the supply voltage can only be set to low signal), and with the ignition relay 15 is closed. If the vehicle is moving, the signal at the output of the amplifier 14.3 becomes low, and the relay 15 opens.

Hijacker easily can conduct electrical continuity of contacts of the relay 15 is turned on and the ignition key is turned off, if the vehicle is standing still. In this case, the operation and the electrical parameters of the detecting node 6 functional block body is impossible. If you try to bring the vehicle in motion, then, first of all, the poll is in a moving vehicle is very difficult, and, secondly, the duration of the self-vehicle movement is very short, because almost immediately triggered to lock preventing movement of the vehicle. In General, the method of electrical continuity when enabling and disabling the ignition not applicable for the identification of nodes 6 functional block body.

If the ignition is switched on by the hijacker, the low signal from the output of the amplifier 14.3, getting on the control input unit 18 test contact groups, translates the block 18 testing of the contact groups in the search mode circuit contacts relay contacts 15. If in the absence of the enabling signal to the relay coil 15 contacts of the contact group that the relay 15 still be closed, the circuit can produce only the crosspiece 17, connected in parallel to the contacts to the stroke group relay 15.

Measuring, for example, the resistance between the contacts of the relay contacts 15, block 18 testing contact group records (resistance change circuit) the presence of the jumper 17 in the circuit block of this functional body and sends the appropriate alarm signal to the nonvolatile memory 19 which stores the alarming signal.

To close the switch, the jumper 17 can only employee service center, checks the correctness of the prescribed secret jumpers 17 with the toggle switch. Unit 18 test pin groups captures every case of such a circuit and sends it for storage in non-volatile memory 19. In addition can be remembered and closing time jumpers 17 (if non-volatile memory 19 has the function built-in clock).

It should be noted that when the ignition is turned off (that is, when the break switch 9 in the ignition) the information recorded in the nonvolatile memory 19 is retained. The ability to retain stored information when power is removed is the primary function of the non-volatile memory 19.

Now consider the work of the anti-theft system for a vehicle after the ignition is produced by one of the users. This user, as noted above, must be identified and at the output of the decoder 13 has the SFD is to morovetsa a single signal. With the closure of the ignition switch 9 D-trigger 14.1 set to the zero state. This status cannot be changed until the end of time interval delay of the delay element 11. At the end of the time interval delay for D-flip-flop 14.1 passes the leading edge of the clock signal, on which the D-flip-flop 14.1 logged output signal from the decoder 13. Because driving a vehicle user is, at the output of the decoder 13 is a single signal, and a D-flip-flop 14.1 switches in one state. Then:

signal logic zero at the inverted output of D-flip-flop 14.1 sets the output element AND IS NOT 14.2 (and hence at the output of the amplifier 14.3) constant high signal, normally open relay 15 and preventing the block 18 test pin groups conducting the search circuit of the contact groups of the relay 15. That is, the operation mode of the relay 15 is fully consistent with the mode of operation of a normally open motor relay;

signal of the logic unit to direct the output of D-flip-flop 14.1, getting on the control input non-volatile memory 19, causes the non-volatile memory 19 outputs the accumulated information about the closure of the relay contacts 15 in the absence of the enabling signal to the relay coil 15 (unless, of course, this accumulated information is available in the nonvolatile memory 19). At the end of the renditions is this information nonvolatile memory 19 is completely cleaned. The output of the non-volatile memory 19 via the encoder 20 and the second block 21 of the agreement on the communication channel 5 enters the processing unit 4.

Connected to the processor unit 4 unit 22 of the display is configured to receive from the processor unit 4 signals indicating the presence in the circuit of the functional block of the vehicle body crosspieces 17 and that at least once this link has been closed by the toggle switch. This alarm indication is generated in the processor unit 4 after the reception of the communication channel 5 connected in series through the encoder 20 and the second block 21 approval of at least one alarm signal circuit toggle switch installed on the crosspiece 17, recorded in the nonvolatile memory 19.

As noted above, such transfer on the channel 5 may be carried out by radio - in the case of using a wireless communication channel, for example, in the format of a Bluetooth or wires in the presence of TS multiplex (e.g., CAN) bus or the transmission of data via on-Board power supply.

In block 22 of the display shows the ID of the blocked functional body, and also the time when there was a record of an alarm signal in the nonvolatile memory 19 of the corresponding node 6 functional block body. Time can be displayed only if vigoron is dependent memory 19 has the function built-in clock.

It should again be noted that the indication in the vehicle installed by hackers jumper 17 occurs only in the case when it was preceded by identification of the TS user using the wearable part 1 unit 2 remote user authentication. The employee service center, not having specified a wearable part 1, may not, therefore, to establish the fact of fixation in non-volatile memory 19 alarm about the jumper settings 17.

This means that the user, for the first time including the ignition after the return of the vehicle from the garage, immediately receives full information about the fact that his vehicle has one or more open jumpers preventing anti-theft system (in terms of blocking certain functional bodies). After that, the user can easily take measures to prevent theft (including, to find and remove the jumper 17).

Thus, the present invention is solved - created anti-theft system for vehicles, with a higher than the device prototype, the level of opposition to theft of the vehicle.

This is achieved by the provision of timely warnings to the user's vehicle on the presence of at least one secretly installed in collusion with the hijacker in the circuit functional block body TC PE is amicci 17, the neutralizing effect of the corresponding node 6 functional block of the authority during theft of the vehicle. In developed enterprise-applicant and implementing the anti-theft system for vehicle warning respective user happens after return of the vehicle from the garage, as soon as the user turns the ignition.
