摘　　要：广州地铁3号线列车在一个牵引系统故障时,列车自动运行(ATO)模式下停车有时会产生冲标。应用列车系统自身工具软件,采集了列车正常运行、1个ICU(逆变器控制单元)故障、2个ICU故障等三种状态下的相关数据,通过数据格式转换对数据进行了对比分析。列车ICU故障后,由于低速时列车需要进行气制动补充,而电-气制动转换过程中出现的总制动力波动,导致了列车冲标现象的发生。When a traction system of the train with ATO mode operation is out of work on Guanzhou metro Line 3, the train is possible to exceed the stop mark. If the distance between the stop point and the stop mark is more than 50 cm, the door of the train can＇t be opened automatically, so the train must move again and the train delay will innevitably occure. Through analyzing the data which is gathered by the train service software, this paper hopes to find the reasons and the solution.
