车身模块偶发休眠异常的深入研究及分析

In-depth Study and Analysis of Occasional Dormancy Anomaly of the Body Control Module

车身控制模块休眠问题是整车设计时必不可少的考虑因素之一。本文针对某车型车身控制模块偶发休眠异常故障,通过对车身控制模块原理和休眠条件的研究、满足休眠条件的判断软件逻辑分析、 BCM休眠模块代码逻辑分析、 BCM休眠模块软件分析等方面进行深入研究,最终使此问题得以解决。

The body control module sleep problem is one of the essential considerations in design of the whole vehicle. For the problem of occasional dormancy anomaly of the body control module of a certain vehicle type,through in-depth research and analysis on the principle of the body control module and sleep condition, the software logic analysis of the judgment of the sleep condition, the logic analysis of the code of the BCM sleep module, and the software analysis of the BCM sleep module, the problem is eventually solved.
