US 11,028,887 B2 · Method and apparatus for correcting physical slip and wear coefficient of clutch

Abstract

A method and apparatus for correcting a physical slip and wear coefficient of a clutch comprising obtaining a torque difference according to a positional relation between an engine and the clutch; obtaining a correction weight value corresponding to an engine torque according to the torque difference; and correcting the physical slip and wear coefficient according to the correction weight value and a running-in state of the clutch. The method relates to obtaining a torque difference in real time by means of a positional relation between the engine and the clutch in a manner corresponding to the positional relation, obtaining a correction weight value corresponding to the engine torque according to the torque difference, and further correcting the physical slip and wear coefficient by combining the correction weight value and a running-in state of the clutch.
