Vehicle anti-theft method and vehicle anti-theft system

Abstract

The invention discloses a vehicle anti-theft method and a vehicle anti-theft system, which utilize a tyre module, a short-distance wireless key module and a central module to realize the theft prevention of vehicles. The short-distance wireless key module transmits an encrypted tyre module startup verification code to the tyre module, the tyre module receives, decrypts and verifies the verification code and encrypts the central module to start and transmit the verification code when the verification code passes the verification, and the central module receives, decrypts and verifies the verification code and starts the vehicle locking when the verification code passes the verification; and the short-distance wireless key module transmits an encrypted tyre module locking verification code to the tyre module, the tyre module receives, decrypts and verifies the verification code and encrypts the central module to lock and transmit the verification code when the verification code passes the verification, and the central module receives, decrypts and verifies the verification code and performs the vehicle locking when the verification code passes the verification. The invention increases the privacy of the verification codes and the complexity of verification procedures, improves the reliability of the verification process and the difficulty of the decryption of the verification codes, and strengthens the anti-theft performance of the anti-theft system and the safety of the vehicles.

Description

technical field [0001] The invention belongs to the technical field of vehicle anti-theft, and in particular relates to a vehicle anti-theft method and a vehicle anti-theft system based on a tire pressure monitoring system. Background technique [0002] During the running of the vehicle, what the drivers are most worried about and the most difficult to prevent is the tire blowout problem, which can cause or induce serious traffic accidents, especially when driving at high speed, the tire blowout will be more dangerous. In order to prevent tire blowouts, the tire pressure monitoring system has gradually become a necessary configuration of the vehicle. The tire pressure monitoring system can monitor the tire pressure status at all times during the driving process of the vehicle. When the tire pressure is abnormal, it will alarm and deal with it in time. Fundamentally avoid the problem of tire bursting, significantly improving the safety of vehicles. The current tire pressure ...
