A device for the automatic actuation of a friction clutch (1) in the transmission line of a motor vehicle between an internal combustion engine (3) and a change-speed gear (5) controls the clutch (1) through a setting drive system (11) controlled by a control system (19, 25, 31) in starting driving in dependence upon the engine rotation rate (n) and in the changing of higher gears with predetermined setting speed. A sensor device (33, 45, 57) generates a gear rotation rate signal corresponding to the input rotation rate of the gear (5) and the control system increases a clutch ideal-position signal in dependence upon the engine rotation rate signal by a proportion of the gear rotation rate signal which corresponds to a predetermined fraction of the gear input rotation rate. <IMAGE> |
