集成IMMO的车身控制器设计

Design and development of body control module integrated IMMO

为提高汽车的防盗安全性,设计了集成发动机防盗锁止系统（IMMO）的车身控制器。发动机防盗锁止系统由转发器、防盗控制单元和发动机控制单元组成。根据防盗控制单元的特性,将防盗控制单元集成至车身控制器中,转发器、车身控制器和发动机控制单元的通信认证能够防止非法启动车辆。阐述了该车身控制器的软硬件设计,而且针对发动机防盗功能进行了通信认证测试和实验测试。结果表明该车身控制器能够实现发动机防盗功能,性能可靠稳定,且具有广泛的应用前景。

In order to improve the anti-theft security of the vehicle,a body control module integrated immobilizer（IMMO）was designed.Immobilizer system consists of transponder,anti-theft control unit and engine control unit.According to the charact-eristics of the anti-theft control unit,the anti-theft control unit was integrated into the body control module,and the communication authentication of the transponder,the body control module,and the engine control unit can prevent illegal starting of the vehi-cle.The hardware and software design of the body control module was elaborated and a communication authentication test and experiment test were conducted on the engine antitheft function.The result shows that the engine anti-theft function of the body control module can be realized,the performance is reliable and stable,and it has a wide range of application prospect.
