The invention relates to a clutch torque correction method and device and a storage medium. Under the condition that the clutch meets the self-learning activation condition, the self-learning engine error rotating speed is obtained, and the online correction torque is determined according to the self-learning engine error rotating speed; on-line correction limiting torque is determined according to the on-line correction torque, the first fixed slope and the corresponding operation time, and corrected on-line correction inheritance torque is determined according to the vehicle running state, the clutch state parameters and the on-line correction inheritance torque matrix; on-line error compensation torque is determined according to the on-line correction limiting torque and the corrected on-line correction inheritance torque, and on-line error target torque is determined according to the on-line error compensation torque, the vehicle running state, the second fixed slope and the corresponding operation time; and correcting the target torque of the clutch according to the online error target torque. Therefore, the accuracy of clutch position control is improved, and the smoothness of starting and gear shifting processes is improved.
