Abstract

Automatic clutch control to reduce shocks to a vehicle during a rapid switching of a shift lever between its drive D and reverse R positions. The shift lever position and the direction of movement of the vehicle are detected by means of a switch and an electrical circuit. A microprocessor delays the initiation of the clutch engagement by a given time as compared with the clutch engagement occurring when the vehicle is at rest, if the shift lever position is in contra-distinction to the direction of movement of the vehicle, namely, when the shift lever is in its drive D position while the vehicle is moving backward or when the shift lever is in its reverse R position while the vehicle is moving forward.
