Abstract

A clutch engaging torque which will be required by a hydraulically operated clutch to be engaged for a gearshift is preset. A hydraulic pressure required to obtain the clutch engaging torque while the hydraulically operated clutch is at rest is calculated. Then, a corrective action is effected by, for example, subtracting from the hydraulic pressure a centrifugal hydraulic pressure which will be developed in the hydraulically operated clutch by the rotation thereof in the gearshift, thus determining a hydraulic pressure to operate the hydraulically operated clutch.
