Patent ID: 7983827

Claim:
A brake control apparatus for a wheeled vehicle, comprising: a plurality of wheel cylinders adapted to respective ones of wheels of the vehicle; a pump hydraulically connected to the wheel cylinders for pressurizing the wheel cylinders; a motor for driving the pump; a plurality of 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 for performing 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, the control unit being configured to, during the wheel cylinder pressure control, constantly keep a condition that the cross-sectional flow area of at least one of the control valves is maximized.
