    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.

    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: An automatic transmission is provided having a friction element in which, when an ON pressure is supplied to a engaging-side oil chamber, a hydraulic piston is moved and engaged, a lock mechanism enters a lock state, while when an OFF pressure is supplied to a release-side oil chamber, the lock mechanism is released, and the hydraulic piston is moved and released, in which the OFF pressure is supplied to the release-side oil chamber again when a mode of the automatic transmission changes from a mode for engaging the friction element to a mode for releasing the friction element, and when the friction element is not released even if the OFF pressure is supplied to the release-side oil chamber.

    摘要: In friction engagement device having forward clutch 5 and clutch operation pack 6 controlling engagement/disengagement operation of the forward clutch 5, the clutch operation pack 6 has hydraulic piston 61, engagement pressure piston chamber 62, snap ring 64, diaphragm spring 65 and ball lock mechanism BL. The diaphragm spring 65 provides biasing engagement force to the forward clutch 5 at a clutch side of the hydraulic piston 61. The ball lock mechanism BL restrains movement, in a disengagement direction, of the hydraulic piston 61 at a position where the forward clutch 5 is in an engagement state by the biasing engagement force by exerting ON pressure on the engagement pressure piston chamber 62, and after restraining the movement of the hydraulic piston 61, maintains the restraint of the disengagement direction movement of the hydraulic piston 61 even when the ON pressure of the engagement pressure piston chamber 62 is drawn.
