RKE无法可靠唤醒BCM问题分析与改进

RKE does not reliably awakens the BCM problem analysis and improvement

针对某车RKE会出现无法可靠唤醒BCM的问题,在模拟实车安装环境的条件下对故障件进行了大量测试,从理论分析与实际测试两方面总结出产生无法可靠唤醒的主要原因,并提出了解决此问题的软件方案和硬件方案。最后经过大量实车测试验证发现,优化同步码的软件方案能够解决该问题。本文阐述了从故障排查到解决问题的全过程。

Referring to the problem that the RKE can’t reliably awake the BCM for a car,we have conducted extensive tests to its fault under the simulated real-vehicle installation environment.We summarized the main reasons for the inreliably to wake up from two aspects,which is theoretical analysis and practical tests.And we proposed a software programme and a hardware programme to solve this problem.In the end,the real vehicle test proveded that the optimized synchronization code can solve this problem.This article focuses on the entire process from troubleshooting to solving problems.
