发明名称 Flow rate control valve for clutch control device
摘要 A clutch control device for vehicle equipped with a clutch actuator driven by a working fluid, wherein secular change in the flow rate control valve for controlling the working fluid is compensated, and the rate of connection of the clutch is correctly controlled by a simple means. To control the stroke of a clutch actuator 110, the clutch control device is provided with a single flow rate control valve 1 that controls the feed and discharge of the working fluid by using an electromagnetic solenoid. A flow rate control valve control device 9 is provided with a learning device 91 that learns the neutral position of the flow rate control valve 1 which shuts off the flow of the working fluid, separately detects the amounts of electric current to a coil 8 of when the rate of change in the stroke becomes zero depending upon the directions in which the valve body of the flow control valve 1 moves, and learns the central point at the neutral position by averaging the detected values. In controlling the stroke of the clutch, the amount of electric current to the coil 8 is corrected based on the learned value to compensate for a change in the flow rate characteristics by secular changes.
