Patent ID: 7338136

Claim:
A braking device for a vehicle, the braking device comprising: a wheel braking member, a brake operating unit operatively connected to the wheel braking member such that fluid pressure applied to the wheel braking member changes according to the extent of operation of the brake operating unit, a master cylinder operatively connected to the brake operating unit, a fluid loss simulator operatively connected to the master cylinder, the fluid loss simulator capable of applying a hydraulic pseudo reaction force to the master cylinder, a pressure reducing device, and a plurality of fluid pressure sensors for detecting fluid pressure in said master cylinder, wherein said plurality of fluid pressure sensors includes a first fluid pressure sensor and a second fluid pressure sensor; a detection range of said first fluid pressure sensor is lower than that of the second fluid sensor; a detection resolution of said first fluid pressure sensor is higher than that of the second fluid sensor; and wherein when fluid pressure above a prescribed level is applied to said master cylinder, the pressure reducing device relieves the fluid pressure in the master cylinder.
