Abstract
A vehicle brake fluid pressure control apparatus controls operations of a fluid pressure adjusting unit capable of performing adjustment of individually increasing and decreasing brake fluid pressures acting respectively on wheel brakes for front wheels and wheel brakes for rear wheels to be within allowable differential pressures allowable between the brake fluid pressures of the wheel brakes for the left and right coaxial front wheels and the left and right coaxial rear wheels. In the apparatus, a fluid pressure acquiring device acquires a lock fluid pressure of a wheel brake of a wheel coaxial with a wheel being a control target, the lock fluid pressure being a fluid pressure at which pressure decrease by an anti-lock brake control is started. An allowable differential pressure setting device sets the allowable differential pressures matching a road surface friction coefficient on the basis of at least the lock fluid pressure obtained by the fluid pressure acquiring device. The allowable differential pressures stably matching a friction coefficient of a road surface can be thereby obtained.
