The invention provides a motor braking control method and device, a motor controller and a vehicle. The motor braking control method comprises the following steps: judging whether the maximum braking torque of a motor is reduced or not under the condition that a braking system has a fault; if the maximum braking torque of the motor is not reduced, the motor is controlled to compensate the braking torque according to the fault type of the braking system. And if the maximum braking torque of the motor is reduced, the motor is controlled to limit the maximum speed of the vehicle. According to the motor braking control method and device, the motor controller and the vehicle, the safety and reliability of braking control can be improved.

    本申请提供一种电机制动控制方法、装置、电机控制器及车辆。电机制动控制方法包括:在制动系统存在故障的情况下,判断电机的最大制动扭矩是否下降。若电机的最大制动扭矩未下降,根据制动系统的故障类型控制电机对制动扭矩进行补偿。若电机的最大制动扭矩下降,控制电机对车辆的最高车速进行限制。本申请的电机制动控制方法、装置、电机控制器及车辆能够提升制动控制的安全性与可靠性。
