The invention provides a vehicle main contactor welding detection system. A vehicle includes a controller that, in response to data indicative of a voltage associated with an inrush current through a main contactor exceeding a first threshold, commands the main contactor to open and inhibit driving of the vehicle, and command the main contactors to sequentially open and then close in response to the data indicative of the voltage exceeding a second threshold less than the first threshold.
本公开提供了“车辆主接触器焊接检测系统”。一种车辆包括控制器,所述控制器响应于指示与通过主接触器的涌流相关联的电压的数据超过第一阈值,命令所述主接触器断开并禁止驱动所述车辆,并且响应于指示所述电压的数据超过小于所述第一阈值的第二阈值命令所述主接触器顺序地断开,然后闭合。
