<p>PURPOSE:To obtain an optimum clutch control, by supplying pressure oil to and discharging it from two oil chambers partitioned in a cylinder and controlling the oil pressure of a clutch actuator with no influence by a change of the oil pressure in a pump. CONSTITUTION:When a clutch is finely disconnected, a device, first opening a valve 21 for 30msec and closing valve 22-25, forms a hold mode thereafter opens the valve 21, 24, duty controlling the valve 24. When the clutch is disconnected in a maximum speed, the device, opening the valves 21, 24, 25, both supplies pressure oil to an oil chamber 5 and promptly drains pressure oil in an oil chamber 4 thereafter closes the valve 25, coming to duty control the valve 24. In this way, the device, suitably setting an opening o the valves 21-25 and the timing of their opening and closing, enables the clutch to be finely controlled while a delicate clutch condition of half clutch or the like to be controlled.</p> |
