摘要： A clutch control method, including: determining whether a current vehicle state satisfies a condition for a clutch to enter a sliding friction state; if so, controlling the clutch to enter the sliding friction state, and determining a target sliding friction rotating speed of the clutch; determining whether the current vehicle state satisfies a condition for entering a clutch torque deviation collecting state; if so, collecting a torque deviation once and storing the torque deviation; at an end of an adjustment period, accumulating all torque deviations collected previously and taking an average value according to an accumulation number of times, so as to obtain an average torque deviation; if the average torque deviation exceeds a preset deviation threshold, recording the average torque deviation; and if the current vehicle state satisfies a condition for entering a deviation applying state, adjusting a current clutch friction coefficient according to the recorded average torque deviation.
