D-H CURVE CORRECTION FOR COUPLING SYSTEM

摘要

A DH (torque-to-stroke) curve correction method for a clutch system, the method comprising: detecting, by a controller (130), deviations between actual positions of a clutch in first and second torque ranges and a position on a DH curve; wherein the DH curve indicates the relationship between a transmittable torque and a clutch position; determining, by the controller (130), whether the deviation between the actual position in the first torque range and the position on the DH curve is greater than or equal to a first reference value determining, by the control unit (130), whether the deviation between the actual position in the second torque range and the position on the DH curve is less than or equal to a third reference value when the deviation between the actual position in the first torque range and the position on the DH curve greater than or equal to the first reference is worth; andcorrecting, by the control unit (130), a slope of the D-H curve in the ascending direction when the deviation between the actual position in the second torque range and the position on the D-H curve is less than or equal to the third reference value.
