<p>In a brake device of a vehicle in which a braking input side which generates a liquid pressure by manipulating a brake manipulation portion (2) and a braking output side which supplies the liquid pressure to a brake caliper (4) are made to be communicated with each other or being interrupted from each other by way of a first electromagnetic open/close valve (V1), and the brake device includes a hydraulic modulator (6) which adjusts the liquid pressure of the braking output side by operating an electrically-operated motor (23), the brake device includes a first pressure sensor (28A) and a second pressure sensor (28B) for redundantly detecting the liquid pressure of the braking input side, and a trouble diagnosis of the pressure sensors (28A,28B) is performed in response to detection values of the pressure sensors (28A,28B).
The present invention enables a trouble diagnosis of braking-input-side pressure sensors even in a state that a braking input side and a braking output side are interrupted from each other.</p> |
