Abstract
A controllable drive device moves an actuator of a motor vehicle friction clutch between a disengaged position and an engaged position. The drive device adjusts the position of the actuator in the slippage area of the clutch between a position at which torque conversion begins and the engaged position in response to a program control that operates on the basis of an engine's rotating speed and controls the drive device according to a characteristic determined by an engine's speed dependent function generator.
