The invention provides a motor output torque control method and device, a vehicle and a storage medium, the method is applied to the field of vehicle driving, and the method comprises the steps that the rotating speed of a BSG motor is obtained; determining a target torque correction coefficient of the BSG motor according to the rotating speed; based on the target torque correction coefficient and the rotating speed, a corrected first predicted demand torque is determined; and under the condition that the torque difference value of the corrected first predicted demand torque and the second predicted demand torque is smaller than a preset difference value, the BSG motor is controlled to output the corrected first predicted demand torque. According to the method, the first predicted demand torque of the BSG motor can be corrected in combination with the current rotating speed of the BSG motor in the running process of the BSG motor of the vehicle, it is guaranteed that the corrected first predicted demand torque can be updated in time along with changes of the rotating speed, and the corrected first predicted demand torque has high accuracy.

    本申请提供了一种电机输出扭矩的控制方法、控制装置、车辆和存储介质,该方法应用于车辆驾驶领域,该方法包括:获取BSG电机的转速;根据转速,确定BSG电机的目标扭矩修正系数;基于目标扭矩修正系数和转速,确定修正后的第一预测需求扭矩;在修正后的第一预测需求扭矩和第二预测需求扭矩的扭矩差值小于预设差值的情况下,控制BSG电机输出修正后的第一预测需求扭矩。该方法能够在车辆BSG电机运行过程中,结合当前BSG电机的转速,对BSG电机的第一预测需求扭矩进行修正,保证了修正后的第一预测需求扭矩能够随着转速的变化及时更新,使修正后的第一预测需求扭矩具有较高的准确性。
