Abstract
This clutch control device is provided with: a first valve; a second valve; a valve control unit configured to control the operation of each of the first valve and the second valve; an operation determination unit configured to perform an operation determination for the clutch device; and an initial operation completion determination unit which determines whether an initial operation of the clutch device has been completed. The valve control unit, if it is determined by the operation determination unit that an on-off switching process is required, subjects both the first valve and the second valve to opening-control. If it is determined by the initial operation completion determination unit that the initial operation has been completed, the valve control unit subjects the second valve to closing-control.
Claims5
A clutch control device configured to control switching between disengagement and engagement of a clutch device by adjusting an urging force of an elastic member to a clutch member in the clutch device, the urging force being adjusted by controlling movement of a piston of a clutch actuator, and the clutch actuator including a pressure chamber formed in a cylinder, and the piston provided movably in the cylinder in accordance with pressure of a working fluid in the pressure chamber, the clutch control device comprising:
- a first valve provided to adjust the pressure of the working fluid in the pressure chamber;
- a second valve provided to adjust the pressure of the working fluid in the pressure chamber;
- and
- an electronic control unit configured to:
- control operation of each of the first valve and the second valve;
- perform an operation determination of the clutch device;
- and
- determine whether an initial operation of the clutch device is completed when the control of each of the first valve and the second valve is started,
- wherein the controlling of the operation of each of the first valve and the second valve by the electronic control unit includes:
- performing opening control on both the first valve and the second valve when it is determined by the electronic control unit that a disengagement and engagement switching process of the clutch device is necessary;
- and
- performing closing control on the second valve when it is determined by the electronic control unit that the initial operation of the clutch device is completed.
