Abstract
In a method of controlling an automatic clutch arranged between an engine and a drive train of a vehicle in vehicle startup situations wherein the clutch is engaged to such a degree that only a small torque can be transmitted through the clutch and wherein the clutch is increasingly engaged when engine power output is increased, the clutch is immediately returned toward disengagement if, during vehicle startup, the engine power output requirements are suddenly reduced and, after a predetermined delay, the clutch is adjusted to the new situation that is to a standstill of the vehicle or to a renewed startup situation.
Claims4
A method of controlling an automatic clutch arranged between a motor, especially an internal combustion engine, and a drive train of a vehicle in vehicle startup situations, wherein said clutch is automatically engaged to such a degree that only a small torque can be transmitted by the clutch which results in no more than creeping motion of said vehicle but wherein said clutch is increasingly engaged when an engine power output control member is actuated for increased engine power output, and wherein said clutch is immediately returned toward disengagement if, during vehicle startup, said engine power output control member is released and said clutch is then, after a predetermined delay, controlled in adaptation to the new situation--that is to a stand-still of the vehicle with brakes applied or to a renewed startup situation.
