The invention discloses a control method for torque filtering of an electric automobile. The method comprises the following steps: S1, obtaining needed torque of the electric automobile; S2, calculating the torque change rate of the electric automobile; S3, obtaining the limit value of the torque change rate according to the needed torque, and carrying out saturated treatment on the torque change rate of the electric automobile according to the limit value of the torque change rate so as to obtain a final torque change rate; S4, limiting the needed torque according to the final torque change rate so as to obtain initial filtering torque; and S5, carrying out smoothing processing on the initial filtering torque to obtain the final needed torque. According to the control method, under the whole working performance, filtering processing is carried out on the needed torque of the electric automobile, and therefore rapid change of the needed torque of the electric automobile is avoided, so that shaking, caused by rapid change of the needed torque, of the electric automobile is prevented. Impact borne by the electric automobile is reduced, and driving comfort of the electric automobile is improved.
