| 摘 要： | 在ECU软件中，除了独立的故障自诊断模块进行部分故障的监测外，还在其它模块中有许多分散进行的故障检测记录过程，以及当故障发生时所采取的控制策略，根据诊断过程的要求，在自诊断模块中设计相应的4个相应程序分支，即更新记录重要故障，背景故障检测，故障处理与显示及诊断模式分支。

| Abstract: | Besides the supervision and measuring is performed for partial troubles in ECU software by an independent trouble self-diagnosis module,many other trouble measuring and recording processes are also existed and performed dispersively in other modules.The control strategies necessary to be adopted when troubles happened are described.According to the requirements in diagnosis processes,four corresponding program branches are designed in self-diagnosis modules,i.e. updating and recording important trouble,background trouble inspection,troubleshooting and display,diagnosis mode. |
