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.
摘要翻译：控制单元执行接合控制，该接合控制向接合侧油室提供接通压力，以将锁定机构设定为锁定状态，然后在选择行驶模式时降低接合侧油室的液压，并且执行释放控制，当选择非行驶模式时，释放侧油室将释放侧油室提供OFF压力以将锁定机构设置为解锁状态，然后降低释放侧油室的液压。在控制单元确定将摩擦元件控制在接合状态以成为释放状态的情况下，控制单元开始向释放侧油室供给关闭压力以使锁定机构的解锁状态开始向接合侧油室供给液压，降低释放侧油室的液压。

摘要： A transmission controller performs engagement processing, where a forward clutch is engaged and a lock mechanism is brought into a locked state by supplying an ON-pressure to an ON-pressure piston chamber and where the hydraulic pressure of the ON-pressure piston chamber is lowered, and supplies the ON-pressure to the ON-pressure piston chamber when the forward clutch slips even though the forward clutch has been engaged in the engagement processing, while a vehicle is traveling.

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.
