Abstract
A vehicle control apparatus includes: an automatic-stop-and-restart-control-unit stopping/restarting an engine, a brake-fluid-pressure-control-unit controlling wheel-cylinder-pressure using a brake-system, which intensifies brake-manipulation-force by a brake-booster to cause master-cylinder-pressure in a master-cylinder while the engine operates, and which transfers the master-cylinder-pressure to wheel-cylinders to cause the wheel-cylinder-pressure, the brake-system including an actuator automatically increasing pressure in the wheel-cylinders irrespective of the brake-manipulation-force; a negative-pressure-detection-unit which detects the vacuum-pressure; a first-determination-unit which determines whether the vacuum-pressure is not more than a first threshold while the engine stops, a restarting-unit which allows the automatic-stop-and-restart-control-unit to restart the engine when the first-determination-unit determines that the vacuum-pressure is not more than the first threshold; a second-determination-unit which determines whether the vacuum-pressure is not more than a second threshold; and a braking-boost-unit which allows the brake-fluid-pressure-control-unit to automatically increase the pressure in the wheel-cylinders when the second-determination-unit determines that the vacuum-pressure is not more than the second threshold.
