The invention provides a vehicle motor control method and device, a motor controller and a vehicle. The control method of the vehicle motor comprises the steps that the real-time rotating speed and the real-time torque of the motor are obtained; judging whether the motor meets a locked-rotor condition or a low-speed condition according to the real-time rotating speed and the real-time torque; if the motor only meets the locked-rotor condition, it is determined that the motor is in a first working condition, the maximum available torque of the motor is adjusted according to a first duration, and the first duration is the duration after the motor meets the locked-rotor condition; if the motor only meets the low-speed condition, determining that the motor is in a second working condition, and adjusting the maximum available torque of the motor according to the real-time rotating speed; if the motor meets the locked-rotor condition and the low-speed condition at the same time, it is determined that the motor is in a third working condition, and the maximum available torque of the motor is adjusted according to the first duration and the real-time rotating speed. According to the vehicle motor control method and device, the motor controller and the vehicle, the comprehensiveness and reliability of motor control can be improved.

    本申请提供一种车辆电机的控制方法、装置、电机控制器及车辆。车辆电机的控制方法包括:获取电机的实时转速与实时扭矩;根据实时转速与实时扭矩,判断电机是否满足堵转条件或低速条件;若电机仅满足堵转条件,确定电机处于第一工况,根据第一时长调整电机的最大可用扭矩,第一时长为电机满足堵转条件后的时长;若电机仅满足低速条件,确定电机处于第二工况,根据实时转速调整电机的最大可用扭矩;若电机同时满足堵转条件与低速条件,确定电机处于第三工况,根据第一时长与实时转速调整电机的最大可用扭矩。本申请的车辆电机的控制方法、装置、电机控制器及车辆能够提升电机控制的全面性与可靠性。
