Title:
APPARATUS AND METHOD FOR LEARNING FILLING PARAMETERS FOR A CLUTCH
Document Type and Number:
WIPO Patent Application WO/2014/140041
Kind Code:
A3
Abstract:
A method and a device for calibrating a wet clutch is provided. The clutch comprises a pump, a piston, a proportional valve, a controller, and a pressure sensor. The method comprises the steps of closing the clutch by sending a pressure profile with fill parameters from the controller to the proportional valve, recording a pressure signal of the hydraulic fluid, comparing the pressure profile with the pressure signal, determining whether at least one defined feature is in the pressure signal that is indicative of errors in the fill parameters, and if said feature is determined in the pressure signal, modification of the pressure profile by changing at least one of the fill parameters.
