摘要： A vehicle control device includes control means for executing coasting control, in which a friction engaging element is disengaged and a rotation speed of a rotary shaft of a drive source is set at zero, when a shift range corresponds to a travel range and a coasting condition is established, and the control means executes the coasting control when the shift range is modified to a neutral range.

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 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.
