<P>PROBLEM TO BE SOLVED: To hardly receive influence of an outside air temperature, to perform more stable brake fluid pressure control and to enhance performance when a brake fluid is pressurization-controlled. <P>SOLUTION: In the brake fluid pressure control device for the vehicle, braking action of a wheel brake B by a brake fluid pressure can be performed at the wheel brake B side even in the any state that an output fluid pressure passage D communicating from a master cylinder C with the wheel brake B side is communicated or disconnected by a separation valve 11. A simulator 12 and a detection means 1a for detecting the brake fluid pressure are provided on the master cylinder C side and a pump 24 operated based on the detection by the detection means 1a and a suction valve 27 for releasing or disconnecting a suction fluid pressure passage F are provided on the wheel brake B side. An air-tight closed brake fluid storage chamber 15 in which the brake fluid flows-in from the suction fluid pressure passage F at stopping of the pump 24 and the brake fluid flows out toward the pump at operation of the pump 24 is provided between the separation valve 11 and the suction valve 27. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
