Method for controlling a clutch and regulating a scheduled torque level during starting procedure operates a clutch automatically in a motor vehicle's drive mechanism for comfortable vehicle starting.

摘要

A vehicle (1) has a driving engine (2), a clutch (3) and a transmission (4) fitted with a first drive shaft (5) to drive two second drive shafts (7a,7b) by means of differential gearing (6). The clutch is a dry friction clutch with a pressure plate (10), a clutch disk (11), a disengaging bearing (12) and a disengaging fork. A pressurized actuator (15) operates the clutch with an electric motor (19). During the starting procedure torque transferred from the clutch is controlled as a function of a throttle pedal and/or of the throttle pedal's timing speed change. Through an increase in engine RPMs during throttle pedal operation and through clutch moment transferred from the clutch, so much torque is transferred onto the drive wheels that the vehicle starts off. The throttle pedal is operated and engine moment rises to a preset level that corresponds to the throttle pedal operation.
