Embodiment Construction

[0073] The present invention will be described in further detail below with reference to the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0074] An anti-theft vehicle control system, such as figure 1As shown, it includes vehicle bus, central control unit, engine control unit, automatic transmission control unit, brake control unit, mobile communication control unit, parameter storage unit and user information exchange unit, and also includes

[0075] A ciphertext bus for transmitting encrypted information;

[0076] A plaintext converter for encrypting plaintext or decrypting ciphertext when communicating between the vehicle bus and the ciphertext bus;

[0077] A number of common vehicle keys used to start the vehicle;

[0078] One is equipped with a password processing module and stores the private key of the car owner. When the car is lent or lost, the car owner's digital signature is performed, and the K...

Abstract

The invention discloses a vehicle control system for preventing stealing and robbery, comprising a central control unit, an engine control unit, an automatic variable speed control unit, a brake control unit, a mobile communication control unit, a parameter storage unit, a user information exchange unit and a vehicle owner key, which are all provided with an encode processing module; besides, the vehicle control system also comprises a plaintext and ciphertext converter, a ciphertext bus, an ordinary vehicle key and a vehicle owner key; and the invention has another purpose of providing a method for implementing the vehicle control system, and the method includes the steps of (1) initialization; (2) start-up process; and (3) emergent verification. By adopting the technologies of confidentiality, verification and threshold, the invention effectively improves the safety of vehicles, prevents other people from illegally driving the vehicle and illegally changing elements on the ciphertext bus, and the method for handling the case of loss of an ordinary vehicle key is simple.

Description

technical field [0001] The invention relates to the field of automobile anti-theft, in particular to an anti-theft vehicle control system and a realization method thereof. Background technique [0002] Current vehicle anti-theft devices can be divided into three categories: mechanical locks, electronic anti-theft and remote monitoring. Mechanical locks are widely used, but the cost of illegal unlocking continues to decrease. At present, it is generally considered that the security is insufficient, so it is rarely used alone. Electronic anti-theft is in the development stage. The common method is to send information through electronic keys. After receiving the information, the anti-theft device of the vehicle compares it with the preset information, and then unlocks or locks according to the comparison results. Now there are some imitation electronic keys. The device that sends the message. Remote monitoring is the remote monitoring and control of vehicles through wireless ...
