Abstract
A vehicle brake fluid pressure control apparatus includes a control unit including a memory part for storing a valve closing map which shows a relationship between a differential pressure between an upstream side and a downstream side of a pressure regulator valve and an output current value for closing the pressure regulator valve and a valve opening map which shows a relationship between the differential pressure and an output current value for opening the pressure regulator valve. The control unit executes a current value switching control in which the output current value of the valve closing map is changed to that of the valve opening map and thereafter, the output current of the valve opening map is changed to an output current value which lies somewhere between the output current values of the valve closing map and the valve opening map.
