Anti-theft system and anti-theft method for vehicle

Abstract

The invention provides an anti-theft system and an anti-theft method for a vehicle, and relates to the field of vehicle safety. The anti-theft system comprises a first controller, a second controllerand an anti-theft lock, wherein the first controller is used for generating an authentication request instruction after receiving an unlocking request; the second controller is connected with the first controller and is used for carrying out authentication interaction with the first controller after receiving the authentication request instruction and generating an unlocking instruction after theauthentication interaction is passed; and the anti-theft lock is arranged in a gear shifting mechanism of the vehicle, is connected with the second controller and is used for releasing an N gear in the gear shifting mechanism according to the unlocking instruction so as to unlock the vehicle. According to the scheme, the scheme can effectively prevent a new energy electric vehicle from being stolen.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to an anti-theft system and an anti-theft method for vehicles. Background technique [0002] Anti-theft methods for vehicles in the prior art include locking the steering column, locking the transmission system, or locking the shifting mechanism. At present, the most mature method is to lock the steering column, but this method has complex structural design, and when the system fails, it is easy to cause the anti-theft system to lock the steering column. If the vehicle is driving at this time, the steering column will be locked. If it is stuck, the steering wheel will not be able to turn, resulting in serious traffic accidents. The second is the lock shift mechanism. For example, for vehicles with automatic transmission, the lock P gear can be used to realize the anti-theft of the whole vehicle, but this method is only applicable to vehicles with automatic transmissions, while new ene...

Problems solved by technology

At present, the most mature method is to lock the steering column, but this method has complex structural design, and when the system fails, it is easy to cause the anti-theft system to lock the steering column. If the vehicle is driving at this time, the steering column will be locked. Holding it will cause the steering wheel to be unable to turn, resulting in serious traffic accidents

The second is the lock shift mechanism. For example, for vehicles with automatic transmission, the lock P gear can be used to realize the anti-theft of the whole vehicle, but this method is only applicable to vehicles with automatic transmissions, while new energy electric vehicles do not have automatic transmissions. Therefore, this method is not suitable for new energy electric vehicles
