ABSTRACT:
A brake control apparatus for a wheeled vehicle includes wheel cylinders; a pump hydraulically connected to the wheel cylinders for pressurizing the wheel cylinders; a motor for driving the pump; control valves hydraulically connected between the pump and respective ones of the wheel cylinders for allowing fluid communication therebetween with respective variable cross-sectional flow areas; a pressure sensor for measuring an internal pressure of each of the wheel cylinders; and a control unit. The control unit performs wheel cylinder pressure control of controlling the internal pressures of the wheel cylinders by the motor and the control valves so as to conform the measured internal pressures of the wheel cylinders to respective ones of desired internal pressures of the wheel cylinders. During the wheel cylinder pressure control, the control unit constantly keeps a condition that the cross-sectional flow area of at least one of the control valves is maximized.
