    Abstract: A vehicle which can improve fuel consumption without a driver feeling uncomfortable is provided. The vehicle includes: a hydraulic pressure sensor for acquiring a brake torque value which increases in accordance with a stepping-in amount of a brake pedal by the driver, and an ECU which automatically stops an engine after a basic time has elapsed since a basic condition is satisfied and then automatically restarts the engine. The ECU automatically stops the engine before the basic time elapses, when an increment of the brake torque value from a reference value after the basic condition is satisfied is equal to or greater than an additional stepping judgment value, and a shortened time shorter than the basic time has elapsed.

    Abstract: An intake control system for an internal combustion engine, which, even when there are a plurality of intake air amounts for attaining one target torque, is capable of positively selecting a minimum intake air amount therefrom without causing hunting, and setting the minimum intake air amount as a target intake air amount, thereby making it possible to improve fuel economy. The intake control system calculates a maximum intake air amount, sets a plurality of provisional intake air amounts within a range of 0 to the maximum intake air amount, calculates torques estimated to be output from the engine with respect to the provisional intake air amounts, respectively, selects a minimum provisional intake air amount that makes the estimated torque equal to or close to the target torque from the relationship between the provisional intake air amounts and the estimated torques, and sets the same as the target intake air amount.

    Abstract: A vehicle controlling device includes: a VSA-ECU that performs deceleration control of a host vehicle using an inter-vehicle distance between the host vehicle and another vehicle traveling in front of the host vehicle; and an engine control unit that performs idling stop control of stopping drive of an engine as a driving source of the host vehicle upon satisfying stop conditions including a condition that vehicle speed of the host vehicle enters a predetermined low vehicle speed range and performs restart control of restarting the engine upon satisfying a predetermined restart condition. A power supply mounted on the host vehicle is used in common as a power supply used in executing the deceleration control and a power supply used in executing the restart control. The engine control unit prohibits execution of the idling stop control during execution of the deceleration control.
