Title:
CLUTCH CONTROL METHOD, CONTROL APPARATUS, STORAGE MEDIUM, AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/123985
Kind Code:
A1
Abstract:
A clutch control method, comprising: after entering a waiting state (S201), determining whether a current vehicle state satisfies a condition for the clutch to enter a slipping state (S202), if the current vehicle state satisfies the condition, controlling the clutch to enter the slipping state, and determining a current slipping speed, corresponding to a current gear, of the clutch (S203); then determining whether the current vehicle state satisfies entering a state of collecting a torque deviation of the clutch (S204), if the current vehicle state satisfies entering the state of collecting the torque deviation of the clutch, collecting one torque deviation, and storing the torque deviation (S205); at the end of an adjustment period, accumulating all previously accumulated and collected torque deviations, and calculating an average value according to the number of accumulations, to obtain an average torque deviation, and if the average torque deviation exceeds a preset deviation threshold, recording the average torque deviation (S206); and if the current vehicle state satisfies entering a deviation application state (S207), adjusting a current clutch friction coefficient according to the average deviation (S208). Further provided are a control apparatus, a storage medium, and a program product. According to the clutch control method, automatic adjustment of the clutch friction coefficient can be implemented, and accurate control of a clutch torque is implemented.
