The invention discloses a fault diagnosis processing system and method for EMT automatic transmission of a pure electric commercial vehicle. For the automatic transmission for EMT, a system comprisinga fault diagnosis module, a fault acquisition module, a fault processing module, a fault analysis module and a fault application module is designed. According to the system, all faults of related parts of the EMT are counted; finally, the service life of the part, the service life of the part corresponding to each fault and external information are obtained, so that a worker or a driver and passengers can clearly see possible faults of the speed changer in operation, and then relevant treatment is carried out in advance; the system analyzes and processes specific faults of the EMT automatic transmission of the pure electric commercial vehicle, so that various problems caused by faults of the automatic transmission are solved effectively.

    本发明公开了一种纯电动商用车EMT自动变速器故障诊断处理系统及方法;针对EMT自动变速器,设计了包括故障诊断模块、故障采集模块、故障处理模块、故障分析模块和故障应用模块的系统,该系统将EMT自动变速器相关零部件所有的故障统计出,最终得出零部件的使用寿命,各个故障发生时对应的零部件使用寿命和外部信息,使得工作人员或驾乘人员能够清楚的运行中的变速器有可能发生的故障,进而提前做出相关处理;该系统针对纯电动商用车EMT自动变速器特有的故障进行分析处理,能够有效对解决因自动变速器故障带来的各个问题。
