The invention provides a torque control method, device and equipment and a computer readable storage medium. The method comprises the steps that the current slip angle and the current yaw velocity of a target vehicle are obtained; according to the current slip angle, a preset expected slip angle, the current yaw velocity and a preset expected yaw velocity, a target sliding mode control function is solved, a target control quantity is obtained, and the target control quantity comprises a torque difference value of the left side and the right side of the target vehicle; the target sliding mode control function is obtained according to a target sliding mode surface function and a target reaching law function; and controlling the target vehicle according to the torque difference value. Compared with traditional PID control, the physical state and the physical characteristics of the vehicle meet the sliding mode control function, and the stability and the accuracy of torque control can be improved in the face of external interference or parameter change.
