Abstract

A completely electronic circuit operating from the respective outputs of a motor speed transducer and a transmission input speed transducer and from other inputs which are usually constant voltages calculates a control signal for moving the control member of an automatic clutch for coupling a vehicle motor to a vehicle transmission during slipping engagement of the clutch until gripping engagement is made in such a way as to minimize the jolt effect without the necessity of hydraulic or mechanical damping devices.
