摘　　要：描述汽车上CAN总线报文通信丢失的故障排查思路,从信号源控制器、传输线路、信号目标控制器进行展开分析,并形成故障树分析方法。在实车上的故障案例中,根据该故障树分析可以及时准确地检测出报文通信丢失的原因。故障原因被成功找到并能够被人为再现,充分表明故障树分析方法是高效正确的。A detailed description of the CAN bus missing is given, and the analysis is carried out from perspectives of signal source controller, transmission line and signal target controller. And the fault tree analysis is formed. In the case of a real vehicle, according to the fault tree analysis, the cause of the message loss can be detected timely and accurately. The cause of the failure is successfully identified and can be reproduced artificially, which fully indicates that the fhuh tree analysis method is efficient and correct.
