Patent ID: 8447486

Claim:
A brake control apparatus that controls braking forces which are applied to wheels based on a pressure of hydraulic fluid, comprising: a manual hydraulic pressure source that pressurizes hydraulic fluid based on an amount by which a brake operation member is operated by a driver; a first hydraulic circuit which connects a first wheel cylinder that applies a braking force to a first wheel to the manual hydraulic pressure source, and in which a passage is formed so that a pressure of the hydraulic fluid in the manual hydraulic pressure source is transferred to the first wheel cylinder; a second hydraulic circuit which connects a second wheel cylinder that applies a braking force to a second wheel, which differs from the first wheel, to the manual hydraulic pressure source, and in which a passage is formed so that the pressure of the hydraulic fluid in the manual hydraulic pressure source is transferred to the second wheel cylinder; a partition valve that is provided in a main passage which provides communication between the first hydraulic circuit and the second hydraulic circuit; a first pressure sensor that detects pressure in the main passage at a position on the first hydraulic circuit side with respect to the partition valve; and a suppression device that suppresses an increase in pressure in the passage in the first hydraulic circuit, to which the first pressure sensor is connected, in a mode, in which a hydraulic pressure is generated directly in the wheel cylinders in response to a brake pedal operation performed by the driver, when the pressure detected by the first pressure sensor is equal to or higher than a predetermined value due to hydraulic fluid pressurized by the manual hydraulic pressure source on the basis of an operation of the driver while the partition valve is closed.
