Abstract:
1. A vehicle brake fluid pressure control apparatus including: 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 so as to prevent the front wheels and the rear wheels from being locked during braking; an allowable differential pressure setting unit which sets allowable differential pressures allowable between the brake fluid pressures of the wheel brakes for the left and right coaxial front wheels and between the brake fluid pressures of the wheel brakes for the left and right coaxial rear wheels; and an estimated vehicle body deceleration calculating unit which calculates an estimated vehicle body deceleration of a vehicle, wherein the operation of the fluid pressure adjusting unit being controlled such that each of the differential pressures between the brake fluid pressures of the wheel brakes for the left and right coaxial front wheels and between the brake fluid pressures of the wheel brakes for the left and right coaxial rear wheels is equal to or lower than a corresponding one of the allowable differential pressures set by the allowable differential pressure setting unit, and the allowable differential pressure setting unit sets the allowable differential pressures so as to correspond to a road surface friction coefficient based on the estimated vehicle body deceleration calculated by the estimated vehicle body deceleration calculating unit.
