The invention relates to the technical field of motor controllers, in particular to a motor controller fault processing method and system, a vehicle and a storage medium, and the method comprises the steps: responding to a condition that a motor controller is in a power-on or operation stage, detecting that a driving circuit has a fault through a main control chip of the motor controller, and executing fault recovery operation, detecting whether the fault of the driving circuit is cleared or not; if it is detected that the fault of the driving circuit is removed, the motor controller operates normally; if it is detected that the drive circuit fault is not cleared and the number of times of executing the fault recovery operation is smaller than a preset number threshold, continuing to execute the fault recovery operation; and if it is detected that the drive circuit fault is not cleared and the number of times of executing the fault recovery operation is greater than or equal to a preset number threshold, executing a response action based on the working stage of the motor controller according to a preset strategy. The influence of the failure of the driving chip and the power module on the operation of the electric drive can be eliminated, and the interference on the current running state of the vehicle is avoided.
本发明涉及电机控制器技术领域,具体涉及一种电机控制器故障处理方法、系统、车辆及存储介质,所述方法包括:响应于电机控制器处于上电或运行阶段,且通过电机控制器的主控芯片检测到驱动电路存在故障,执行故障恢复操作,并检测驱动电路故障是否清除;若检测到驱动电路故障已清除,则电机控制器正常运行;若检测到驱动电路故障未清除,且执行故障恢复操作次数小于预设次数阈值,则继续进行执行故障恢复操作;若检测到驱动电路故障未清除,且执行故障恢复操作次数大于等于预设次数阈值,则按预设策略基于电机控制器所处工作阶段执行响应动作。其能够消除驱动芯片和功率模块故障失效对电驱运行的影响,避免对车辆当前的行驶状态产生干扰。
