The invention discloses a torque correction method and device, a controller and a storage medium, and the method comprises the steps that power parameters, motor parameters and vehicle parameters are obtained, the power parameters are used for indicating the motion state of a power system of a vehicle, the motor parameters are used for indicating the motion state of a motor of the vehicle, and the vehicle parameters are used for indicating the running condition of the vehicle; predicting according to the power parameters, the motor parameters and the vehicle parameters to obtain a predicted value of the motor speed; when the difference value between the predicted value of the rotating speed of the motor and the reference value of the rotating speed of the motor is larger than a deviation threshold value, the torque instruction is corrected, a corrected torque instruction is obtained, and the torque instruction is used for indicating a torque curve of the motor after torque reversing. The torque instruction is corrected according to the difference value between the predicted value of the motor rotating speed and the reference value of the motor rotating speed, so that the problem that the accuracy of a torque curve obtained through a manual calibration mode in the related technology is poor is solved.
