Abstract

The invention discloses a vehicle body controller, which comprises a low frequency antenna, a radio frequency RF module, a high frequency antenna and high frequency demodulation used for receiving a door opening signal with a roll code, a driving module used for controlling a power supply of the whole vehicle, and a microprocessing controller used as a processing center. The invention also discloses an automobile remote key matched with the vehicle body controller. The automobile remote key integrates a high frequency emitter and a low frequency transponder. The invention also discloses an automobile anti-theft device employing the vehicle body controller. The automobile anti-theft device comprises an engine controller which is connected with the vehicle body controller through a controller area network (CAN) transceiver. Finally, the invention discloses a control method for the automobile anti-theft device. By adopting the technical scheme, the automobile anti-theft coefficient is improved, and an automobile can be prevented from being stolen when a stealer replaces one or several parts to start the automobile.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a body controller, a key matched with the body controller, an automobile anti-theft device using the body controller and a control method thereof. Background technique [0002] Now the anti-theft system of vehicles at home and abroad generally has the following types, engine anti-theft system, body controller with anti-theft function. Generally, the engine anti-theft system and the body controller are two independent systems. The engine anti-theft system is generally divided into three parts: a low-frequency induction coil, a transceiver base station, and an engine anti-theft controller. The engine anti-theft controller generally has circuits such as a main control chip and a communication circuit. The body controller anti-theft system is divided into three parts: the remote control key, the receiver demodulator and the body controller. The body controller generally has circ...
