汽车控制模块掉线问题的分析与解决

Analysis and Solution of the Off-line Issue on Vehicle Control Module

CAN总线通信模块在设计过程中,出现模块掉线的情况很多,掉线的情况又各种各样,增加了分析的难度。本文通过对总线掉线的各种情况展开分析,对底层程序进行软件保护,有效解决了试验过程中的掉线问题,对后续其他CAN总线模块的设计具有借鉴参考价值。

During design process of CAN bus communication module,there are many occasions that the modulegoes off-line,the situation are various,which makes the issue analysis difficult.In this article,by analyzing varioussituations of bus connection dropping,software protection is carried out for the underlying program,and the problemof sudden off-line is solved effectively.It has reference value for the design of the following CAN bus modules.
