Abstract
A clutch control device includes a clutch device, a clutch actuator and a control unit, wherein the control unit performs automatic clutch disconnection control which disconnects the clutch device during a gear shift is performed and a vehicle speed is reduced, and sets a clutch disconnection speed of the automatic clutch disconnection control during the vehicle speed is reduced to a speed lower than a clutch disconnection speed of the automatic clutch disconnection control during the gear shift is performed.
Claims7
1-7. (canceled)
A clutch control device, comprising;
- a clutch device that is configured to disconnect and connect power transmission between a prime mover and an output object of a vehicle;
- a clutch actuator that is configured to operate the clutch device;
- and
- a control unit that is configured to control a drive of the clutch actuator;
- wherein the control unit performs automatic clutch disconnection control which disconnects the clutch device during a gear shift is performed and a vehicle speed is reduced, and sets a clutch disconnection speed of the automatic clutch disconnection control during the vehicle speed is reduced to a speed lower than a clutch disconnection speed of the automatic clutch disconnection control during the gear shift is performed,
- wherein the control unit has:
- an automatic control mode that automatically operates the clutch device by driving the clutch actuator;
- and
- a manual control intervention mode that manually operates the clutch device by an operation input to a clutch operator operated by a driver, and
- wherein, when the vehicle speed or the engine speed is reduced to a predetermined rate change determination threshold value in the manual control intervention mode and when the rate of reduction of the vehicle speed or the engine speed is equal to or greater than a predetermined engine stall avoidance determination threshold value, the automatic clutch disconnection control is performed at a clutch disconnection speed which is greater than when the rate of reduction is less than the predetermined engine stall avoidance determination threshold value.
