ABSTRACT:
A braking control apparatus for a vehicle includes four wheel braking apparatuses for applying a braking torque to wheels, a first hydraulic pressure generating apparatus generating a hydraulic pressure, a vacuum booster generating an assist force for assisting a breaking operation, a first hydraulic circuit, a second hydraulic circuit, a second hydraulic pressure generating apparatus generating an assist hydraulic pressure that is added to the hydraulic pressure, a detecting portion for detecting a braking operation variable, a target value determining portion for determining a first assist hydraulic pressure target value and a second assist hydraulic pressure target value to be both greater than zero over a range where the braking operation variable is greater than a predetermined value at which the assist force by the vacuum booster is started, and a pressure regulating portion for regulating the assist hydraulic pressure to match the assist hydraulic pressure target value.
