Patent ID: 7630815

Claim:
A brake control apparatus, comprising: a plurality of wheel cylinders that apply braking force to respective wheels of a vehicle in response to a supply of a hydraulic fluid to the wheel cylinders; a manual hydraulic pressure source that pressurizes a hydraulic fluid in accordance with an operation of a brake performed by a driver and sends the pressurized hydraulic fluid to the wheel cylinders; a cut valve which is arranged in a hydraulic fluid delivery path between the manual hydraulic pressure source and the wheel cylinders, and to which a force is applied in such a direction that the cut valve is closed when a hydraulic pressure in the wheel cylinders is higher than a hydraulic pressure in the manual hydraulic pressure source; a pressure-decreasing valve that decreases the hydraulic pressure in the wheel cylinders; a partition valve that divides the hydraulic fluid delivery path into a first system through which the hydraulic fluid is supplied to at least one of the wheel cylinders and a second system through which the hydraulic fluid is supplied to the other of the wheel cylinders; and a controller that controls a discharge path, through which the hydraulic fluid is discharged from the wheel cylinders, wherein the hydraulic fluid delivery path is formed in such a manner that communication is mechanically provided through the first system and the second system, between the manual hydraulic pressure source and the wheel cylinders, in a non-controlled state, and wherein the controller opens at least one of the pressure-decreasing valve and the partition valve in response to a release of the brake in a case where a braking force is generated by delivering the hydraulic fluid through the hydraulic fluid delivery path in accordance with the operation of the brake in the non-controlled state.
