<p>PROBLEM TO BE SOLVED: To solve such problems that a charge of a working fluid to a hydraulic clutch in gearing takes a long time and an electromagnetic proportion pressure control valve is inferior in controllability (control accuracy) in low pressure area because of the mechanism. SOLUTION: In a hydraulic clutch control system wherein a connection is made by supplying the working fluid of predetermined pressure to the hydraulic clutch provided for every each shift of transmission through electromagnetic change-over valves 14, 16, 20, 22; accumulators 10, 11 having the combination of quick filling ability and low pressure area controllability enhancement facility with respect to the hydraulic clutches 15, 17, 21, 23 are provided in supply lines of the working fluid from a fluid pressure pump 1 to the electromagnetic change-over valves 14, 16, 20, 22.</p> |
