The invention discloses an electric vehicle motor torque active damping control method, electronic equipment and a storage medium, and belongs to the technical field of electric vehicle control. The shock absorption and noise reduction performance of the electric automobile is improved. A permanent magnet synchronous motor model is constructed based on a permanent magnet synchronous motor vector control method; designing a first-order low-pass filter; designing a Butterworth filter; and performing vector control on the electric vehicle motor by using the constructed permanent magnet synchronous motor model, and modulating the voltage of the two-phase static coordinate system into six paths of switching signals for controlling the on-off and on-off of a three-phase inverter of the electric vehicle motor. Inputting the obtained rotating speed current of the electric vehicle motor into a first-order low-pass filter to carry out first-order low-pass filtering on the rotating speed current of the electric vehicle motor, inputting the rotating speed current of the electric vehicle motor after the first-order low-pass filtering into a Butterworth filter to carry out second-order filtering, and judging; and performing active damping control on the motor torque of the electric vehicle by the obtained arbitration torque. The damping device is used for damping and noise reduction.
