    Patent number: 8335624
    Abstract: A pressure sensor detects the change in pressure within a cylinder in a clutch master cylinder in a case where a clutch shifts from a connected state to a disconnected state. The pressure within the cylinder is detected at a time point where a rate of the pressure increase is changed. The position of a rod in this case or the rotation angle of a motor in an actuator is detected as a touch point preparation position. The touch point preparation position is a stage preceding power generated by an engine being transmitted to the clutch. The actuator moves the rod at high speed until the position of the rod reaches the position corresponding to the touch point preparation position.
