<p>PURPOSE:To drive a clutch actuator smoothly at a transition process to a connected state from a disengaged state. CONSTITUTION:A piston 5p in a clutch actuator 5 to disengage or connect a clutch before and after the shift of a transmission automatically selecting shift speeds is intermittently driven in making a resting point in the midway shifting to a connected state from a disengaged state as a pause, and on the other hand, any disarray in piston disengaged at the time of selection from static friction to dynamic friction is eliminated by way of continuing a micropressure feed by a sub control valve 23 so as to continue a slow speed advance without stopping it even in the midway resting point, thus a smooth clutch engagement is realized.</p> |
