Abstract: A vehicular brake device that implements ESC/TRC control suppresses hydraulic pressure variations produced during open/close control of a brake actuator holding valve or depressurizing valve. While a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply target wheel cylinder pressure to respective wheel cylinders, the target servo pressure is set to a first predetermined target servo pressure smaller than a maximum output pressure of the servo pressure generating device. When wheel cylinder pressure supplying control starts, the target servo pressure is set as 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 below the first determined target servo pressure.

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: Provided is a braking device capable of suppressing an overshoot or undershoot in output pressure. This vehicle braking device is configured such that a pressure adjustment unit has a piston which is driven by the difference between force corresponding to pilot pressure and force corresponding to output pressure, and a control unit estimates, on the basis of a stroke-related value regarding the amount of movement of the piston, the amount of change of the output pressure that changes even after switching from pressure increase control or pressure reduction control to holding control of the output pressure, and controls a valve unit on the basis of the estimated amount of change of the output 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.
