METHOD AND APPARATUS FOR CORRECTING PHYSICAL SLIP AND WEAR COEFFICIENT OF CLUTCH

Document Type and Number:

WIPO Patent Application WO/2019/149226

Kind Code:

A1

Abstract:

A method and apparatus for correcting a physical slip and wear coefficient of a clutch. The method for correcting a physical slip and wear coefficient of a clutch comprises: 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 for correcting a physical slip and wear coefficient of a clutch relates to obtaining a torque difference in real time by means of a positional relation between an engine and the clutch in a manner corresponding to the positional relation, obtaining a correction weight value corresponding to an 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, such that the physical slip and wear coefficient is not limited to be corrected in the case of a small rotation speed difference interval and can be corrected at any time, and thus the comprehensiveness and flexibility of physical slip and wear coefficient correction is improved.
