The embodiment of the invention provides an electric vehicle anti-shake method, device and equipment and a computer readable storage medium. The method comprises the steps that a rotating speed signal and a torque instruction are obtained; determining the rotating speed of the motor according to the rotating speed signal; performing first filtering processing on the rotating speed of the motor to determine a speed difference value; based on the speed difference value, the equivalent acceleration of the motor is determined; the first filtering processing represents band-pass filtering processing and low-pass filtering processing; performing second filtering processing and gain compensation processing based on the equivalent acceleration, and determining a current compensation value; the second filtering processing represents low-pass filtering processing; based on the current compensation value, third filtering processing and superposition processing are carried out, and a current instruction value is determined; and according to the current instruction value, anti-shake processing of the electric vehicle is realized. And the third filtering processing represents high-pass filtering processing, so that the anti-shake processing effect of the electric vehicle can be improved.
