The invention relates to a vehicle active anti-shake method, an anti-shake system, a storage medium and a vehicle, and the vehicle active anti-shake method comprises the following steps: carrying out band-pass filtering on a collected motor rotation speed signal to obtain a rotation speed shake component; calculating the compensation torque of the motor according to the rotating speed jitter component; and outputting a motor control torque in combination with the required torque and the compensation torque. Because the jitter component of the motor rotating speed is obtained through band-pass filtering of the motor rotating speed signal, the compensation torque of the vehicle can be directly calculated according to the jitter component. Compared with a previous anti-shake method, a complex calculation model does not need to be established to calculate the ideal rotating speed of the motor, and the anti-shake method is simplified. And the compensation torque is calculated according to the rotating speed jitter amount, so that the compensation torque and the rotating speed fluctuation are ensured to be in the same phase, and the active anti-jitter performance of the vehicle is improved.

    本发明涉及一种车辆主动防抖方法、防抖系统、存储介质及车辆,其中一种车辆主动防抖方法,其包括以下步骤:对采集的电机转速信号带通滤波获得转速抖动分量;根据转速抖动分量计算电机的补偿扭矩;结合需求扭矩及上述补偿扭矩输出电机控制扭矩。由于通过对电机转速信号带通滤波获取了电机转速的抖动分量,可直接根据抖动分量计算车辆的补偿扭矩。相比之前的防抖方法,不需要建立复杂的计算模型计算电机的理想转速,简化了防抖方法。且由于是根据转速抖动量计算补偿扭矩,就保证了补偿扭矩和转速波动同相位,改善了车辆主动防抖性能。
