摘　　要：以CA6124SH8混合动力汽车上匹配的CA-85HPT2 AMT为研究对象,根据解析冗余、故障树分析、基于系统动作反馈等原理,运用Matlab/Simulink搭建AMT系统故障诊断模型,再以混合动力汽车远程监控数据采集系统采集实车运行数据作为仿真模型输入参数,通过读取模块将参数输入诊断模型中,从而判断AMT系统各个单元故障情况。试验结果证明了故障诊断的准确性,对今后解决匹配AMT系统的混合动力汽车高故障率问题意义重大。Taking AMT system CA-85HPT2 for HEV CA6124SH8 as the research object, the fault diagnosismodel of AMT system is established by Matlab/Simulink according to the theories of analytical redundancy, fault treeanalysis and system action feedback. The vehicle running data are collected by the remote monitoring and dataacquisition system for HEV. Then, the data are sent to the fault diagnosis model as input parameters to judgewhether each AMT component is in fault. The test results show the accuracy of this fault diagnosis and it issignificant in solving the problem of high fault rate of HEV with AMT.
