Abstract
In a brake control device and a brake control method, when a shift to a brake mode for backup involving separation of a supply path of working fluid is performed at the time of detection of an abnormality during braking, a differential pressure acting between an outlet opening and an inlet opening of an open-close valve which is provided between a hydraulic pressure source that is used during the backup brake mode and wheel cylinders and which needs to be opened during the backup brake mode is lessened prior to the separation of the supply path of working fluid so that the open-close valve is opened in accordance with a valve-opening command. Therefore, at the time of switch of the control mode, the confinement of wheel cylinder pressure is avoided.
