Title:
SYSTEM AND METHOD TO PREDICT THE REMAINING USEFUL LIFE OF A CLUTCH BY COEFFICIENT OF FRICTION ESTIMATION
Document Type and Number:
WIPO Patent Application WO/2015/035204
Kind Code:
A3
Abstract:
A system and method for determining a remaining useful life of a portion of a wet clutch system is provided. The system comprises a first clutch assembly, a proportional valve, a sensor, and a controller. The proportional valve regulates a pressure applied to the first clutch assembly. The sensor measures a response of the first clutch assembly during one of engaging and disengaging a first portion of the first clutch assembly with a second portion of the first clutch assembly. The controller controls the proportional valve, calculates a mean coefficient of friction of the first clutch assembly based on the sensed response of the first clutch assembly, and determines a remaining useful life of a portion of the wet clutch system based on the mean coefficient of friction of the first clutch assembly.
