Abstract
A vehicle brake fluid pressure control apparatus includes: a controller configured to control fluid pressures in wheel brakes to increase or reduce by controlling normally open electromagnetic valves and normally closed electromagnetic valves, wherein the controller perform: a pressure reducing in a pressure reducing cycle in which a basic pressure reducing control and a gradual pressure control are performed continuously in a case that the controller determines to execute a pressure reducing control with wheel speeds decreasing; a pressure reducing control in a basic pressure reducing amount in the basic pressure reducing control; and a temporary holding control for holding the fluid pressure and a fine pressure reducing control for executing a pressure reducing in an amount smaller than the basic pressure reducing amount in a case that the wheel speeds tend to decrease after the temporary holding control in the gradual pressure reducing control.
