摘要： A vehicle is provided with: a drive system clutch (Fwd/C) disposed between the engine (1) and drive wheels (7); a torque converter (2) disposed between the drive system clutch (Fwd/C) and the engine (1) and equipped with a lock-up clutch (9), in which the magnitude of power transmission is controlled by hydraulic pressure; and an electric oil pump (50) capable of supplying hydraulic pressure while the engine (I) is stopped. Said engined car coasts as a result of sailing stop control in which, when a sailing stop travel condition is met, power transmission by the drive system clutch (Fwd/C) is blocked and the engine (1) is stopped. While coasting under sailing stop control, hydraulic pressure for putting the lock-up clutch (9) into a power-transmitting state is applied to the lock-up clutch (9).

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： A transmission controller determines whether a vehicle is going to stop based on a driving condition of the vehicle. When it is determined that the vehicle is going to stop, a lock mechanism is placed in an unlocked state through a supply of an OFF pressure to an OFF pressure piston chamber even if a D mode is selected by a select switch.

摘要： A vehicle control device includes control means for executing coasting control to disengage a friction engaging element and set a rotation speed of a rotary shaft of a drive source at zero when a predetermined condition is established, the predetermined condition including at least a condition according to which an accelerator pedal is not depressed. The control means starts the coasting control after predicting that an actual speed ratio of a continuously variable transmission will be modifiable to a target speed ratio of the coasting control during the coasting control, even in a case where the accelerator pedal is not depressed but the actual speed ratio has not yet reached the target speed ratio.

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： 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.
