Abstract:
A vehicular brake fluid pressure control apparatus includes: normally open and normally closed electromagnetic valves disposed to correspond to plural wheel brakes; and a control unit which controls fluid pressures transmitted to the wheel brakes by controlling drive currents applied to the electromagnetic valves according to plural different fluid pressure control modes. The control unit controls the normally closed electromagnetic valves while switching, according to which of the fluid pressure control modes is effective, between a responsivity priority control in which drive currents applied to the normally closed electromagnetic valves are increased to a target current value instantaneously at a first slope, a silence priority control in which the drive currents are increased at a second slope gentler than the first slope, and an intermediate control in which the drive currents are increased at a third slope gentler than the first slope and steeper than the second slope.
