摘　　要：为了解决AMT故障自诊断过程中经常出现的故障多报或误报的问题,对AMT系统的故障类型和部件耦合性进行了系统分析,提出使用故障先验概率密度动态计算故障优先级的方法.实际应用结果表明,该方法能够对故障进行解耦合,可有效降低故障判断的计算难度,提高故障判断的实时性和准确性.In order to solve the problems of the location error in the process of the AMT fault diagnosis, the fault types and the component correlation of the AMT system are analyzed. The faults prior is calculated dynamically by the fault probability. The results show that the method can decouple the relationship between the faults, effectively reduce the computational difficulty of the fault judgment, and improve the real-time capabilty as well as the accuracy of the algorithm.
