Abstract: A vehicle brake device provided with a hydraulic pressure generating portion, an actuator and a controlling portion which maintains a driving force of the driving portion when a control subject pressure in a control subject chamber is within a dead zone, wherein the control subject pressure varies in response to a variation of the master pressure and a pulsation is generated in the master pressure accompanying an operation of the actuator. The vehicle brake device further includes a rigidity information obtaining portion which obtains a rigidity information and a dead zone setting portion which sets the dead zone based on the rigidity information obtained by the rigidity information obtaining portion such that the higher the rigidity of the control subject chamber, or the higher the probability of rigidity increase of the control subject chamber, the wider the dead zone is set.

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.

Abstract: The brake control device comprises a control mode selecting portion 64 which selects one control mode based on a detection result of the detecting portion from a control mode group including at least two control modes which are a responsiveness priority mode which gives more priority to a responsiveness of the braking force relative to an operation of a brake operating member than to a suppression of an operating noise occurred upon the generation of the preparatory hydraulic pressure and a serenity priority mode which gives more priority to the suppression of the operating noise than to the responsiveness of the braking force. The hydraulic pressure control portion controls the hydraulic pressure generating device to generate the preparatory hydraulic pressure in response to the control mode selected by the control mode selecting portion.
