Abstract: A control device for a multi-stage automatic transmission-equipped vehicle includes a hydraulic power controller, a combustion controller configured to, if a predetermined combustion stop condition is satisfied when the vehicle is traveling, perform deceleration-period combustion stop control, and limit combustion restart triggered by a reduction in rotational speed of an internal combustion engine, during execution of the deceleration-period combustion stop control, and a motoring controller configured to control the rotational drive of the internal combustion engine by a motor during execution of the deceleration-period combustion stop control so that the rotational speed of the internal combustion engine is maintained at a predetermined rotational speed during a period of time from the time that the rotational speed of the internal combustion engine decreases to the predetermined rotational speed until downshifting to a predetermined gear ratio is completed.

Abstract: A vehicle system comprises a brake system comprising a brake pedal and a braking mechanism configured to apply a braking force to a vehicle, and a vehicle control unit operable to automatically stop an engine when the vehicle is decelerated to a given vehicle speed or less during traveling. When it is detected that the brake pedal is manipulated and the vehicle is stopped after automatically stopping the engine, the vehicle control unit is operable to control the braking mechanism to increase the braking force from a current value according to a manipulation amount of the brake pedal up to a given value.
