The invention provides a bus voltage fault processing method and device, a motor controller and a vehicle. The bus voltage fault processing method comprises the following steps: when a motor controller is in a working mode, judging whether a bus voltage signal is in an invalid state or not; and on the basis that the bus voltage signal is in the invalid state, the whole vehicle is monitored, and whether the whole vehicle is in the running state or not is judged. And on the basis that the whole vehicle is in the running state, the torque of a motor is adjusted through a bus voltage replacement value, and the bus voltage replacement value is determined according to the voltage value of a power battery pack and the voltage value of a direct-current converter. According to the bus voltage fault processing method and device, the motor controller and the vehicle, the stability and driving experience of the whole vehicle can be improved.

    本申请提供一种母线电压的故障处理方法、装置、电机控制器及车辆。母线电压的故障处理方法包括:在电机控制器处于工作模式时,判断所述母线电压信号是否处于无效状态。基于所述母线电压信号处于无效状态,对整车进行监控,并判断所述整车是否处于运行状态。基于所述整车处于运行状态,采用母线电压替代值对电机的扭矩进行调整,所述母线电压替代值根据动力电池包的电压值与直流转换器的电压值确定。本申请的母线电压的故障处理方法、装置、电机控制器及车辆能够提升整车的稳定性和驾驶体验。
