Abstract
A vehicle control device which is applicable to a vehicle brake device, controls the pressure increasing control valve and the pressure decreasing control valve so that an actual servo pressure detected by the servo pressure sensor becomes a target servo pressure and sets a control dead zone in which a control of the pressure increasing control valve and the pressure decreasing control valve is prohibited to be an area which has a first predetermined width from the target servo pressure when a normal braking operation is performed and sets the control dead zone to be an area which has a second predetermined width, wider than the first predetermined width when the brake actuator executes the braking control which accompanies a brake fluid pumping back control, wherein the brake fluid supplied to the wheel cylinder is returned to the master cylinder by pumping back operation of the built-in pump.
