FLOW CONTROL VALVE FOR CLUTCH CONTROL DEVICE |
摘要 |
A clutch control device for vehicle is equipped with a clutch actuator driven by a working fluid, and works to correctly control the rate of connection of the clutch by a simple means compensating secular change of a flow rate control valve that controls the working fluid. The clutch control device has a single flow rate control valve 1 for controlling the feed and discharge of the working fluid to change the stroke of the clutch actuator 110. The flow rate control valve 1 has a neutral position at where feed and discharge of the working fluid is stopped. A flow rate control valve control device 9 is provided with a learning device 91 for learning the neutral position. To control the stroke, the flow rate control valve control device 9 corrects the amount of electric current to a coil 8 of an electromagnetic solenoid based on a value learned by the learning device 91 and compensates a change in the flow rate characteristics caused by secular change. The neutral position is learned when the rate of change in the stroke is substantially zero.
