摘　　要：当发动机启动继电器出现粘连后,导致启动马达一直处于旋转的工作状态,最终出现启动马达烧毁的后果。针对此问题,提出一种基于蓄电池压降变化的故障诊断算法,来准确识别上述故障。最后建立模型并验证算法的有效性。When the engine starter relay is sticking,the starter will keep working for all the time.At last,the starter is damaged.For solving this error,we develop an algorithm based on the battery voltage changing tendency.At last we set up the module according the above new algorithm to verify its usefulness.
