Title:
METHOD FOR DETERMINING A POINT OF APPLICATION OF THE CLUTCH FOR AN AUTOMATIC GEARBOX
Document Type and Number:
WIPO Patent Application WO2004074025
Kind Code:
A3
Abstract:
The invention relates to a method for determining a point of application of the clutch of an automatic gearbox without a synchronised reverse action. The aim of said invention is to improve the determination of the point of application avoiding the use of sensorial information on an engine. For this purpose, the point of application is determined as each point of the clutch releasing where a torque transmitted by the gearbox is sufficiently important for releasing the teeth (3) of a sliding sleeve (1) in a tooth-to-tooth position against the teeth (4) of the clutch body (2) of the reverse gear toothed wheel.
