Abstract
A hydraulic brake pressure controller and method for pressure increase in a wheel cylinder of a hydraulic brake pressure controller is adapted to obtain favorable ABS control performance in light of the vehicle driving road surface and the stepping force of the brake pedal involves adjusting the pressure increase output time of the pulse pressure increase from a master cylinder to the wheel cylinder based on the pressure differential between the master cylinder hydraulic pressure and the wheel cylinder hydraulic pressure of each wheel cylinder. The wheel cylinder hydraulic pressure of each wheel cylinder is calculated based on an estimated vehicle deceleration obtained from an estimated vehicle speed.
