Patent ID: 8219294

Claim:
A method for actuating a clutch ( 6 ) of a drivetrain of a motor vehicle such that, when one of the motor vehicle is rolling downhill with an accelerator pedal not being actuated and when the motor vehicle is coasting on level ground with the accelerator pedal not being actuated, a clutch position of the clutch ( 6 ) being determined as a function of a rotational speed difference between an input speed of a transmission ( 2 ) of the drivetrain and an idling speed of a power engine ( 1 ) of the drivetrain, the method comprising the steps of: initiating determination the clutch position of the clutch ( 6 ) when the motor vehicle is either rolling downhill or coasting on level ground while the accelerator pedal is unactuated; determining via a processor the rotational speed difference between the transmission input speed and the power engine idling speed; determining the clutch position from the rotational speed difference between the transmission input speed and the power engine idling speed, and correcting the clutch position in either an engaging direction or a disengaging direction depending on at least one parameter that depends on acceleration of the motor vehicle.
