The invention discloses a motor torque control method and device, an electric vehicle and a readable storage medium. The motor torque control method comprises the steps that the actual torque and the actual temperature of a motor are obtained in real time; when the actual torque is greater than or equal to the peak torque of the motor, determining the first overload time of the motor according to the first unit time, the first initial time and the first actual temperature; starting torque limitation on the motor according to the first overload time; after torque limitation is started on the motor, second overload time of the motor is determined according to second unit time, second initial time and second actual temperature of the motor; and according to the second overload time, closing torque limitation on the motor. Therefore, timeliness and accuracy of motor torque control are improved.
本申请公开了一种电机扭矩控制方法、装置、电动车辆及可读存储介质,电机扭矩控制方法包括:实时获取电机的实际扭矩与实际温度;在实际扭矩大于等于电机的峰值扭矩的情况下,根据第一单位时间、第一初始时间与第一实际温度确定电机的第一过载时间;根据第一过载时间,对电机开启扭矩限制;在对电机开启扭矩限制后,根据电机的第二单位时间、第二初始时间与第二实际温度确定电机的第二过载时间;根据第二过载时间,对电机关闭扭矩限制。由此,提高了电机扭矩控制的及时性与准确性。
