A vehicle control apparatus includes: a VSA-ECU and an ESB-ECU that perform braking control to apply a braking torque in response to a brake operation by a driver of a host vehicle, and also perform brake holding control to hold the braking torque even when the brake operation is cancelled; and an engine control unit that performs idling stop control to stop driving of an engine that is a drive source of the host vehicle when a stop condition is satisfied, including that a vehicle speed of the host vehicle enters a predetermined low vehicle speed region, and also performs restart control to restart the engine when a predetermined restart condition is satisfied. The engine control unit prohibits execution of the idling stop control during execution of the brake holding control.

Vehicle control apparatus and vehicle equipped with vehicle control apparatus

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.

Start and stop control for a vehicle

A vehicle equipped with an automatic stop/restart system for an internal combustion engine includes a hydraulic continuously variable transmission and a parking mechanism. The continuously variable transmission changes power of the internal combustion engine using hydraulic pressure boosted by rotational driving force of the internal combustion engine. The parking mechanism holds the vehicle stationary by locking, with a locking member, the rotation of a power transmitting member between the internal combustion engine and driving wheels when a shift position is in a parking range. In an automatic stop state of the internal combustion engine, when the shift position is in the parking range and brakes are turned off, an electronic control unit executes restart if an inclination angle of the vehicle is greater than or equal to a predetermined value, and maintains the automatic stop state if the inclination angle is smaller than the predetermined value.
