Abstract
This apparatus is applied to a vehicle brake apparatus provided with a hydraulic booster operated by utilizing an accumulator hydraulic pressure that is adjusted to a predetermined high pressure (not less than a lower limit value) by a drive control of a hydraulic pump. This apparatus executes an automatic pressurization control by controlling plural solenoid valves with the use of the accumulator hydraulic pressure. The increasing slope of the brake hydraulic pressure during the automatic pressurization control is determined on the basis of the vehicle motion state. The increasing slope is restricted to be not more than a predetermined restriction value, in the case where the accumulator hydraulic pressure at the time of starting the automatic pressurization control is less than 'a reference hydraulic pressure that is greater than a minimum value of the accumulator hydraulic pressure necessary for assisting the brake operation by the hydraulic booster and smaller than the lower limit value'.
