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.

    本申请涉及一种离合器扭矩的修正方法、装置和存储介质。在离合器满足自学习激活条件的情况下,获取自学习发动机误差转速,并根据自学习发动机误差转速确定在线修正扭矩;根据在线修正扭矩、第一固定斜率和对应的运算时间,确定在线修正限制扭矩,并根据车辆运行状态、离合器状态参数和在线修正继承扭矩矩阵,确定修正后的在线修正继承扭矩;根据在线修正限制扭矩和修正后的在线修正继承扭矩,确定在线误差补偿扭矩,并根据在线误差补偿扭矩、车辆运行状态、第二固定斜率和对应的运算时间,确定在线误差目标扭矩;根据在线误差目标扭矩,对离合器目标扭矩进行修正。据此,提高了离合器位置控制的准确性,改善了起步和换挡过程平顺性。
