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 controls so as to increase the target servo pressure by a predetermined amount, while the brake actuator is executing the braking control which accompanies a brake fluid pumping back control wherein the brake fluid supplied to the wheel cylinder is pumped back to the master cylinder by the built-in pump.

Abstract: Vibrations of a hydraulic pressure in an upstream portion due to operations of a slip control device during anti-lock control are transmitted to a control pressure chamber via a pressurizing piston of a master cylinder and a control piston of a regulator. During anti-lock control, in contrast, a pressure-increase linear valve and a pressure-reduction linear valve are opened, allowing change in volume of the control pressure chamber, resulting in reduction in stiffness. This reduction suppresses vibrations of a hydraulic pressure in the control pressure chamber, resulting in suppression of vibrations of a hydraulic pressure in a front pressure chamber. As a result, it is possible to reduce the lowering in control accuracy for a hydraulic pressure in a brake cylinder in anti-lock control using the hydraulic pressure in the front pressure chamber, which can well avoid a long braking distance.
