Abstract
A device for controlling a motor vehicle clutch is disclosed. A hydraulic control system coupled to the disengagement lever of a clutch selectively engages and disengages the clutch responsive to a control signal. The control signal is generated by a control circuit which receives a first signal representative of the speed of the vehicle and a second signal representative of the rotary speed of the engine. The control circuit varies the control signal during each engagement of the clutch as a function of two components: a first component which initially varies as a substantially linear function of the speed of the vehicle and thereafter varies as a positive exponential function of the speed of the vehicle; and a second component which varies as a substantially linear function of the speed of the engine. Both components vary in a direction which drives the clutch further into engagement for increasing vehicle and engine speed.
