A control device is provided with a flow rate derivation part for deriving a pressure-holding-valve flow rate on the basis of a pressure command value and a previous pressure command value; a differential pressure derivation part for deriving a differential-pressure-valve differential pressure value so that the differential-pressure-valve differential pressure value increases with an increase in the difference obtained by subtracting the pressure-holding-valve flow rate from a pump-discharge flow rate; and a pressure-holding-valve processing part for performing an aperture derivation process to derive a command aperture so that the command aperture decreases with an increase in the difference obtained by subtracting the pressure command value from the sum of an pressure value and the differential-pressure-valve differential pressure value, and driving a holding pressure valve at the command aperture.

Brake control device for vehicle

A vehicle braking control device includes: an indicated-value-setting unit for setting an indicated current value, which relates to a differential pressure valve provided to a channel between a master cylinder and a wheel cylinder, to a value corresponding to a required differential pressure; and a depressurization-starting differential pressure acquisition unit for acquiring, as a depressurization-starting differential pressure, the differential pressure at the point in time when a pressurizing state for increasing the differential pressure caused by the differential pressure valve transitions to a depressurizing state for reducing the differential pressure caused by the differential pressure valve. The area between the depressurization-starting differential pressure and a boundary differential pressure is set as a depressurization-starting differential pressure area. When the depressurizing state is in effect and the required differential pressure is included in the depressurization-starting differential pressure area, the indicated-value-setting unit sets the slope of decrease of the indicated current value.

Braking control device for vehicle

A control signal output unit (a drive control unit) executes control to retain a gear position corresponding to a motor generator during deceleration of a vehicle and regeneration executed by the motor generator.
