Abstract: A vehicle brake device includes a pressure adjusting device wherein as the volume of a pilot chamber is changed by the movement of a piston and the flow rate of liquid flowing in and out of the pilot chamber increases, the amount of movement of the piston increases with reference to the piston position in an equilibrium state where the force corresponding to the pilot pressure and the force corresponding to the output pressure are balanced, whereby the flow rate of the liquid flowing in and out of an output chamber increases. A control device, when judged by a limitation necessity judging portion that the gradient of output pressure should be limited, implements at least one of pressure increasing gradient limit control for opening a pressure decreasing electromagnetic valve under pressure increasing control, or pressure decreasing gradient limit control for opening a pressure increasing electromagnetic valve under pressure decreasing control.

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.

Abstract: The vehicle braking device performs a control which makes an actual value of physical quantity associated with a braking force follow a target value thereof when the actual value is outside a dead zone and a control which suppresses a change of the actual value when the actual value is within the dead zone and includes a judging portion which judges whether or not the actual value passes through the dead zone with a value beyond the upper limit threshold value and a setting portion which sets a second upper limit threshold value more closely approximated than a first upper limit threshold value when the actual value is judged not to pass through the dead zone, as the upper limit threshold value, when the actual value is judged to pass through the dead zone by the judging portion.

Abstract: In a vehicular brake device, while a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply the target wheel cylinder pressure to the respective wheel cylinders individually, the vehicle control device sets the target servo pressure to a first predetermined target servo pressure which is a value smaller than a maximum output pressure of the servo pressure generating device. When the execution of the wheel cylinder pressure supplying control starts, the vehicle control device sets the target servo pressure to be the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is smaller than the first determined target servo pressure.

Abstract: The vehicle control apparatus gives a control current to the electromagnetic control valve at a start of energization of the electromagnetic control valve as a start current value smaller by a first determined amount than an open/closed state change-over reference current value which is necessary for changing over a state of the electromagnetic valve and after the start of energization of the electromagnetic control valve, the control current gradually increases with a smaller increase inclination than an increase inclination of an increase control of the control current which gives priority to a control responsibility of the electromagnetic control valve and finishes a gradual increase of the control current applying to the electromagnetic control valve, when the control current exceeds a finish current value which is larger than the open/closed state change-over reference current value.
