The invention relates to an anti-shake suppression method and device for hill starting of an electric vehicle and a storage medium, and the method comprises the steps that a rotary transformation signal of a motor of a target vehicle is collected in real time, and a rotating speed signal of the motor is calculated according to the rotary transformation signal; performing low-pass filtering on the rotating speed signal to obtain a combined signal of a plurality of harmonic waves; performing high-pass filtering on the combined signal of the plurality of harmonic waves to obtain at least one jitter signal; calculating a jitter compensation torque according to the at least one jitter signal and a preset gain coefficient; and performing torque compensation on the target vehicle based on the jitter compensation torque. According to the method, the accurate jitter signal is obtained through sampling and multi-order filtering of the motor rotary transformer signal, and the compensation torque is calculated according to the jitter signal and the preset gain coefficient; the compensation torque and the instruction torque are compounded to form a synthesized torque value to be output, so that fluctuation of the torque is restrained, and jitter is eliminated.

    本发明涉及一种电动汽车坡道起步防抖抑制方法、装置、存储介质,其方法包括:实时采集目标车辆的电机的旋变信号,并根据所述旋变信号计算所述电机的转速信号;对所述转速信号进行低通滤波,得到多个谐波的合并信号;对所述多个谐波的合并信号进行高通滤波,得到至少一个抖动信号;根据至少一个抖动信号和预设的增益系数,计算抖动补偿扭矩;基于所述抖动补偿扭矩,对目标车辆进行扭矩补偿。本发明通过电机旋变信号的采样和多阶滤波,得到准确的抖动信号,并根据抖动信号和预设增益系数,计算补偿扭矩;通过补偿扭矩与指令扭矩复合形成合成扭矩值输出,从而抑制扭矩的波动,从而消除抖动。
