Claim 0:
1. A brake control apparatus comprising:
a connection fluid passage that connect a master cylinder and a braking force application portion to each other, the braking force application portion being configured to apply a braking force to a wheel according to a brake hydraulic pressure;
a shut-off valve portion provided in the connection fluid passage;
a first pressure sensor configured to detect a hydraulic pressure in a portion of the connection fluid passage that connects the shut-off valve portion and the master cylinder to each other;
a hydraulic pressure source configured to supply brake fluid to a portion of the connection fluid passage that connects the shut-off valve portion and the braking force application portion to each other;
a second pressure sensor configured to detect a hydraulic pressure in the portion of the connection fluid passage that connects the shut-off valve portion and the braking force application portion to each other; and
a control unit configured to determine an abnormality in the first pressure sensor or the second pressure sensor based on a detection value of the first pressure sensor and a detection value of the second pressure sensor after actuating the shut-off valve portion in a valve-opening direction and actuating the hydraulic pressure source.
