The invention belongs to the technical field of new energy engineering machinery, and discloses a torque control method, device and equipment and a storage medium. The required torque is determined according to the position of the accelerator pedal and the rotating speed of the motor; determining a theoretical speed according to the motor speed; determining an acceleration integral vehicle speed according to the longitudinal acceleration signal of the frame; the slip rate is determined and calculated according to the theoretical vehicle speed and the acceleration integral vehicle speed; and performing torque control according to a torque control strategy corresponding to the calculated slip rate based on the demand torque. The required torque and the theoretical vehicle speed are determined by obtaining the position of an accelerator pedal and the rotating speed of a motor, the acceleration integral vehicle speed is determined through an acceleration signal obtained by an acceleration sensor, the actual slip rate is calculated according to the theoretical vehicle speed and the acceleration integral vehicle speed, and finally the torque control strategy corresponding to the calculated slip rate is selected for torque control. Accurate control over the torque is achieved under the condition that the tires are prevented from slipping, tire abrasion during torque control is reduced, and invalid energy consumption is reduced.
