摘要： Provided is a clutch device capable of reducing energy loss caused by clutch-engaging pressure. The clutch control device for an automatic transmission is equipped with: a manual valve (57) for outputting a clutch-engaging pressure when the drive position is selected; a clutch (16) capable of clutch engagement by moving a clutch piston (21) using the supply of the clutch-engaging pressure; a clutch-release valve (54) capable of outputting the clutch-release hydraulic pressure by bypassing the manual valve (57); and a locking mechanism (32) for making it possible to mechanically lock the clutch-piston (21) position in a state of reduced clutch-engaging pressure when the clutch is engaged using the supply of clutch-engaging pressure, and also releasing the lock using the clutch-releasing pressure from the clutch-release valve (54).

摘要： A control unit performs a engaging control, which supplies an ON pressure to a engaging-side oil chamber to set a lock mechanism to a locked state and then decreases the hydraulic pressure of the engaging-side oil chamber, when a running mode is selected, and performs a releasing control, which supplies an OFF pressure to a release-side oil chamber to set the lock mechanism to an unlocked state and then decreases the hydraulic pressure of the release-side oil chamber, when a non-running mode is selected. The control unit supplies the OFF pressure to the release-side oil chamber when the stop of the operation of the driving force source is notified, and allows stopping the operation of the driving force source when the lock mechanism becomes the unlocked state afterward.

摘要： A control unit performs a engaging control, which supplies an ON pressure to a engaging-side oil chamber to set a lock mechanism to a locked state and then decreases the hydraulic pressure of the engaging-side oil chamber, when a running mode is selected, and performs a releasing control, which supplies an OFF pressure to a release-side oil chamber to set the lock mechanism to an unlocked state and then decreases the hydraulic pressure of the release-side oil chamber, when a non-running mode is selected. In the case where the control unit determines to control the friction element in the engaged state to become the released state, the control unit starts supplying the OFF pressure to the release-side oil chamber to cause the unlocked state of the lock mechanism, and starts supplying the hydraulic pressure to the engaging-side oil chamber and reduces the hydraulic pressure of the release-side oil chamber.
