Patent ID: 8007056

Claim:
A brake control apparatus comprising: a first wheel cylinder that applies braking force to a first wheel; a second wheel cylinder that applies the braking force to a second wheel that is different from the first wheel; a manual hydraulic pressure source that pressurizes a working fluid in accordance with an amount of operation of a brake operating member; a first system that communicably connects the manual hydraulic pressure source and the first wheel cylinder, and that transfers working fluid pressure in the manual hydraulic pressure source to the first wheel cylinder; a second system that communicably connects the manual hydraulic pressure source and the second wheel cylinder, and that transfers the working fluid pressure in the manual hydraulic pressure source to the second wheel cylinder; a main channel that communicably connects the first system and the second system; a separation valve provided in the main channel; a pressure control mechanism that controls the working fluid pressure transferred to at least one of the first wheel cylinder and the second wheel cylinder independently of the amount of operation of the brake operating member; and a control device that, when the brake operating member is not operated and the separation valve is closed while a running drive source of a vehicle is stopped, actuates the pressure control mechanism and determines whether the separation valve has an abnormality based on a change in pressure difference between an upstream side and a downstream side of the separation valve.
