Clutch control method and device, storage medium and gearbox controller

The invention provides a clutch control method and device, a storage medium and a gearbox controller, and the method comprises the steps that when a current vehicle state enters a sliding friction state, a target sliding friction rotating speed, corresponding to a current gear, of a clutch is determined; then whether the current vehicle state meets the state of collecting the torque deviation of the clutch or not is judged, if yes, the torque deviation is collected once, the torque deviation is stored, all the torque deviations accumulated and collected before are accumulated and averaged according to the number of accumulated times, and the torque average deviation is obtained; if the torque average deviation exceeds a preset deviation threshold value, recording the torque average deviation; and if the current vehicle state meets the requirement of entering the deviation application state, the current clutch friction coefficient is adjusted according to the recorded average deviation, automatic adjustment of
