    Abstract: 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).

    Abstract: The sensor arrangement structure includes a pulley that rotates about a rotation axis; and a sensor that detects rotation of the pulley. The pulley includes a fixed pulley, a movable pulley that can be displaced relative to the fixed pulley in a direction of the rotation axis, and a plunger defining an oil chamber on a back of the movable pulley. The plunger is provided with a detection target portion in a region that can be visually recognized from the direction of the rotation axis, and the sensor is provided on a support portion that rotatably supports the fixed pulley in a direction along the rotation axis and faces the region in which the detection target portion is provided.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
