Embodiment 1

[0034] In order to simplify the car anti-theft system and save costs, the embodiment of the present invention provides a car anti-theft system, see figure 1 , the system includes: a user identity verification module 101, a transmitter control module 102 and a gearbox control module 103,

[0035] The user identity verification module 101 is configured to receive the remote control key signal carrying user identity information, and send verification application signals to the engine control module and the gearbox control module respectively, and when receiving the engine control module and the gearbox control module return When the first random code, the second random code and the secret key are used, the identity information of the user is verified according to the first random code, the second random code and the secret key, and the verification result is sent to the The engine control module and the gearbox control module; when receiving the first confirmation information and...

Embodiment 2

[0040] In order to simplify the car anti-theft system and save costs, an embodiment of the present invention provides a car anti-theft system, the system includes: a user identity verification module 101, a transmitter control module 102 and a gearbox control module 103,

[0041] The user identity verification module 101 is configured to receive the remote control key signal carrying user identity information, and send verification application signals to the engine control module and the gearbox control module respectively, and when receiving the engine control module and the gearbox control module return When the first random code, the second random code and the secret key are used, the identity information of the user is verified according to the first random code, the second random code and the secret key, and the verification result is sent to the The engine control module and the gearbox control module; when receiving the first confirmation information and the second confi...

Embodiment 3

[0065] In order to simplify the car anti-theft system and save costs, the embodiment of the present invention provides a car anti-theft method applied to the above-mentioned car anti-theft system, see figure 2 , the method includes:

[0066] 201: The user identity verification module receives a remote control key signal carrying user identity information;

[0067] In this embodiment, the remote key signal carrying user identity information can be sent by the user's remote key. When the remote key enters the vehicle or enters a certain range of the vehicle, the remote key sends the remote key signal to the vehicle. Insufficient, if the remote control key signal cannot be sent out, you can put the remote control key close to the anti-theft coil. The engine anti-theft coil is a passive receiving device that can detect the information of the chip in the remote control key. After the module receives the signal, it starts to send verification applications to other modules , can al...

Abstract

The invention discloses automobile anti-theft system and method, belonging to the field of automobile electronics. The automobile anti-theft system comprises a user authentication module, an engine control module and a gear-box control module, wherein the user authentication module is used for receiving a remote control key signal carrying with user identity information, verifying the user identity information according to locally generated random codes and a locally stored key, and controlling a gear-box and / or an engine according to user's commands when the verification result shows that the user identity information is legal. In the invnerion, the conventional mode of matching mechanical key teeth is replaced by the mode of radio frequency verification and mutual verification among modules via a high-speed CAN (Controller Area Network) so that the cost is saved and collision requirements are well met because steering wheel retraction space is left below a steering wheel.

Description

technical field [0001] The invention relates to the field of automobile electronics, in particular to an automobile anti-theft system and method. Background technique [0002] At present, traditional car anti-theft devices are all composed of engine electronic anti-theft and steering mechanism locking system. When starting the engine, a mechanical key is inserted into the keyhole to unlock the steering mechanism locking system. [0003] With the popularity of keyless systems and electric vehicles, the engine start button will replace the traditional mechanical key, and the traditional mechanical key slot will also be cancelled. The general practice in the world is to add an electronic steering column lock to realize the locking function of the steering mechanism. [0004] After analyzing the prior art, the inventor finds that the prior art has at least the following disadvantages: [0005] The structure of electronic steering column lock is complicated, the cost is high, a...
