The invention discloses an anti-shake control method and device for a motor, a vehicle and a storage medium, and the method comprises the steps: obtaining a first actual rotating speed of the motor at a current moment and actual rotating speeds of the motor at previous N-1 moments, inputting the actual rotating speeds corresponding to the N moments into a rotating speed prediction model, and obtaining a predicted rotating speed of the motor at a next moment, determining a target anti-shake torque of the motor according to the first actual rotating speed and the predicted rotating speed, controlling the motor according to the target anti-shake torque, and predicting a future rotating speed value of the motor in advance through a short-term prediction method of a rotating speed prediction model, so that when the anti-shake torque at the current moment is calculated, the anti-shake torque of the motor is calculated. The anti-shake function of the motor is intervened in advance, the hysteresis caused by the fact that anti-shake torque compensation is conducted only after rotating speed shake is detected in a traditional motor anti-shake algorithm is avoided, anti-shake control over the motor is conducted in time, and therefore shake of the whole vehicle is reduced.
本发明公开了一种电机的防抖控制方法、装置、车辆及存储介质,所述方法包括:获取电机在当前时刻的第一实际转速和前N‑1个时刻的实际转速,将N个时刻对应的实际转速输入至转速预测模型,得到所述电机在下一时刻的预测转速,根据所述第一实际转速和所述预测转速确定所述电机的目标防抖扭矩,以根据所述目标防抖扭矩控制所述电机,可以通过转速预测模型的短期预测方法,提前预测电机未来的转速值,使得在进行当前时刻的防抖扭矩计算时,实现电机防抖功能的提前介入,避免因传统电机防抖算法需要检测到转速抖动后才进行防抖扭矩补偿而引起的滞后性,及时进行电机的防抖控制,从而减少整车的抖动。
