Technical Field
The invention relates to the technical field of electric automobiles, in particular to a vehicle anti-theft system.
Background
With the development of scientific technology, vehicle anti-theft technology is increasingly applied to traditional fuel vehicles and electric automobiles. The anti-theft system of the electric automobile on the market at present is generally provided with a vehicle body controller, a vehicle control unit, an electric key and a start button, the start button is pressed, the vehicle body controller receives a low-frequency signal sent by the electric key and verifies the low-frequency signal, if the verification is successful, the vehicle control unit drives a locking machine to unlock, and if the verification is unsuccessful, the vehicle control unit drives a locking mechanism to lock. In the vehicle anti-theft system, the vehicle body controller is only used for verifying the electric key, and the step is easy to be cracked by professional thieves, so that the safety of the anti-theft system is low.
Disclosure of Invention
The invention aims to provide a vehicle anti-theft system to solve the problem of low safety caused by single-stage verification.
In order to achieve the purpose, the vehicle anti-theft system comprises a starting button, an electric key, a keyless entry system, a vehicle body controller, a vehicle control unit and a locking mechanism, wherein the electric key is used for transmitting a low-frequency signal; the keyless entry system is used for receiving a low-frequency signal sent by the electric key and judging the legality of the low-frequency signal; the vehicle body controller is used for receiving and judging the legality of the unique code and the electric key code sent by the keyless entry system; the vehicle control unit is used for receiving and judging the legality of the unique code sent by the vehicle body controller and driving the locking mechanism to unlock and lock.
Further, the keyless entry system judges the validity of the low-frequency signal after receiving the low-frequency signal sent by the electric key, and sends the received code of the electric key and the unique code generated by the keyless entry system to the vehicle body controller in the case of validity.
Further, the vehicle body controller receives and judges the unique code sent by the keyless entry system and the legality of the electric key code, and under the legal condition, the vehicle body controller sends the unique code of the vehicle body controller to the vehicle control unit.
Further, the vehicle control unit receives and judges the legality of the unique code of the vehicle body controller sent by the vehicle body controller; and under the legal condition, the vehicle control unit feeds back the information passing the verification and the unique code of the vehicle control unit to the keyless entry system.
Further, after receiving the information sent by the vehicle control unit, the keyless entry system sends power output control to the vehicle control unit, and the vehicle control unit controls the locking mechanism to unlock.
Further, under the condition that the vehicle control unit is judged to be illegal, the vehicle control unit drives the locking mechanism to be locked.
The invention has the beneficial effects that: the method comprises the steps that a keyless entry system, a vehicle body controller and a vehicle controller in the control system are used for carrying out validity verification on information input by preceding-stage equipment, the subsequent-stage equipment is started when the information is verified to be passed, the locking mechanism is in a locking state as long as the vehicle controller carries out unlocking action or locking action on the locking mechanism, and the safety of a vehicle is effectively guaranteed by the multi-verification mode.

in the figure, 10-start button, 20-electric key, 30-keyless entry system, 40-vehicle body control system, 50-vehicle control system, 60-locking mechanism.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1-2, a vehicle anti-theft system includes a start button 10, an electric key FOB20, a keyless entry system PEPS30, a body controller BCM40, a vehicle control unit VCU50, and a locking mechanism 60, wherein the electric key FOB20 is configured to transmit a low frequency signal, which is transmitted to the keyless system PEPS30 via an antenna after the start button 10 is pressed. The keyless entry system PEPS30 receives a low-frequency signal sent by the electric key FOB20 and judges the validity of the low-frequency signal; in the legal case, the control command, the electric key FOB20 code and the keyless entry system PEPS30 unique code are transmitted to the body control system BCM40 via the CAN bus. The BCM40 receives and judges the legality of the unique code and the electric key FOB20 code sent by the keyless entry system PEPS30, and the vehicle body control system BCM40 sends a control command and the unique code of the vehicle body control system BCM40 to the VCU50 of the whole vehicle control system through the CAN bus after verification. The VCU50 of the vehicle control unit receives and judges the legality of the unique code sent by the BCM40 of the vehicle body and is used for driving the locking mechanism 60 to unlock or lock, and the locking mechanism 60 releases or brakes the locking mechanism 60 through the electromagnetic valve. The vehicle control system VCU50 judges whether the BCM unique code is legal or not, if the BCM unique code is verified, information passing verification and the unique code are fed back to the keyless entry system PEPS through the CAN bus, the keyless entry system PEPS receives the information passing verification and the vehicle control system VCU unique code and then executes corresponding power output control, and after the VCU receives corresponding power control, the VCU drives the electromagnetic valve through a hard wire to control the locking mechanism according to actual working conditions, so that the electronic gear shifter realizes unlocking control.
Under the condition that the judgment is illegal, namely any one of the codes of the electric key FOB20, the keyless entry system PEPS30, the vehicle body controller BCM40 and the VCU50 in the vehicle controller does not meet the verification condition, the electromagnetic valve release locking mechanism 60 realizes the locking control of the electronic gear shifter.
The system greatly improves the safety of the anti-theft system by carrying out three-layer validity verification on the keyless entry system PEPS30, the vehicle body control system BCM40 and the vehicle control system VCU 50.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes which can be made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the claims of the present invention.
