The invention discloses a fault suppression method, device and equipment for a motor controller and a storage medium, and the method comprises the steps: determining an input quantity which comprises voltage, temperature, rotating speed, current or a state bit of a register in a chip; judging whether the motor controller breaks down or not according to the input quantity, and when it is confirmed that the motor controller breaks down, positioning the fault; and based on the linkage relationship between the faults, closing the linkage fault having the linkage relationship with the current fault so as to suppress the current fault of the motor controller. According to the electric drive control system, all states of the whole motor control are monitored, the electric drive system body is protected, meanwhile, fault expansion is avoided, influences on the power and safety of the whole vehicle are avoided, and meanwhile the robustness of the electric drive control system is greatly improved.

    本发明公开了一种电机控制器的故障抑制方法、装置、设备及存储介质,其中该方法包括步骤:确定输入量,所述输入量包括电压、温度、转速、电流或芯片内部寄存器的状态位;根据所述输入量判断所述电机控制器是否发生故障,当确认发生故障时,定位所述故障;基于故障之间的联动关系,将与当前故障具有联动关系的联动故障关闭,以对所述电机控制器的当前故障进行抑制。本申请通过对整个电机控制各个状态进行监控,在保护电驱系统本体同时又避免了故障扩大化,对整车动力和安全造成影响,同时也极大提升了电驱控制系统的鲁棒性。
