The present application discloses a motor torque control method and apparatus, a storage medium and a motor controller. The method comprises: obtaining driving parameters of a vehicle and determining the working condition of the vehicle according to the driving parameters; when determined that the working condition indicates that the vehicle passes through an uneven road surface, obtaining a reference rotational speed, an available maximum torque, and an available minimum torque of a motor corresponding to the driving parameters; on the basis of the actual rotational speed and the motor reference rotational speed, determining an upper limit rotational speed mode coefficient and a lower limit rotational speed mode coefficient; calculating the product of the upper limit rotational speed mode coefficient and the available maximum torque to obtain a target available maximum torque; calculating the product of the lower limit rotational speed mode coefficient and the available minimum torque to obtain a target available minimum torque; and adjusting the output torque of the motor, so that the output torque is greater than the target available minimum torque and smaller than the target available maximum torque. Therefore, torque fluctuation of the motor may be effectively eliminated, and the mechanical structure connected to the motor can be prevented from producing an abnormal noise, ensuring that a new energy vehicle does not produce an abnormal noise when passing through uneven road surfaces.
