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 fastening control, which supplies an ON pressure to a fastening-side oil chamber to set a lock mechanism to a locked state and then decreases a hydraulic pressure of the fastening-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 a 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 a stop of 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 vehicle sailing stop control method is provided for a vehicle including a friction engagement element disposed between a traveling drive source and drive wheels, a torque converter disposed between the friction engagement element and the traveling drive source, and including a lock-up clutch for which a power transmission amount is controlled based on hydraulic pressure, and a hydraulic pressure source that can supply the hydraulic pressure while the traveling drive source is stopped. The vehicle sailing stop control method includes: performing sailing stop control so that coasting is performed by cutting off power transmission of the friction engagement element and stopping the traveling drive source upon a sailing stop travel condition being established; and, during coasting by the sailing stop control, placing the lock-up clutch in a power transmission state in which the hydraulic pressure is applied to the lock-up clutch.
