基于有限状态机的车身防盗报警的实现

摘要

防盗报警功能的设计是汽车技术的一个重要部分,设计了一款车身中央控制器BCM,在实现车身控制的同时实现了防盗报警功能,首先分析了防盗报警单元的工作原理,然后结合汽车的使用方式介绍了汽车防盗报警状态及其状态机管理,最后介绍了防盗报警状态及其转换的提示及警示动作设计,经过装车试验,该防盗报警单元可以有效检测暴力进入,同时防止误报、漏报现象,运行稳定可靠。%Anti-theft alarm is designed to be an important part of automotive technology,the paper designed a central body controller BCM,realized anti-theft alarm function with the body control realization.First,analyzed the alarm unit＇s work mechanism,then introduced anti-theft alarm state and its state machine management combined with the car use,finally introduced the anti-theft alarm state and its conversion tips and alert action＇s design.After loading test,the alarm unit can effectively detect violent intrusion,while preventing false alarm and omission,runs stably and reliably.
