Patent ID: 7300384

Claim:
A method for controlling the position of an automatic disk clutch ( 3 ) as a function of the position of a throttle lever ( 48 , 49 ) arranged in the vehicle, the method being employed when starting the vehicle from stationary or virtually from stationary, in which method a function of the disk clutch ( 3 ) includes to transmit motive force from an internal combustion engine ( 1 ) arranged in a vehicle to an input shaft ( 7 ) of a stage-geared gearbox ( 9 ) arranged in the vehicle, wherein before every new vehicle start, the disk clutch ( 3 ) automatically takes a position (P 21 , P 22 , L), wherein the method comprises taking said position as a function of at least one of the parameters vehicle weight, tractive resistance of the vehicle, or selected transmission ratio between the gearbox input shaft ( 7 ) and the driving wheels of the vehicle so as to take a disk clutch position close to current traction position, said method further including determining a required torque transmitted to the gearbox input shaft ( 7 ) as a function of the position of the throttle lever ( 48 ) and at least one of the said parameters and controlling the position of the disk clutch ( 3 ) according to a measurement of the torque actually transmitted to the gearbox input shaft ( 7 ) in order to achieve a required transmitted torque.
