ABSTRACT:
Method and device for controlling the position of an automatic disk clutch (3) as a function of the position of a throttle lever (48, 49) arranged in a vehicle is disclosed. In some preferred embodiments, the method is employed when starting the vehicle from stationary or virtually from stationary, in which a function (e.g., a primary function) of the disk clutch (3) is to transmit motive force from an internal combustion engine (1) arranged in a vehicle to an input shaft (7) of a stagegeared gearbox (9). The position (48, 49) of the disk clutch is also preferably controlled as a function of at least one of the parameters: vehicle weight; tractive resistance of the vehicle; and the selected transmission ratio between the gearbox input shaft and the driving wheels of the vehicle.
