摘要:
A brake control apparatus for a vehicle includes: a master cylinder for raising a wheel cylinder pressure according to operation of a brake pedal; a booster for raising the wheel cylinder pressure by operating the master cylinder independently of operation of the brake pedal; a pressure regulator provided with a hydraulic pump for raising the wheel cylinder pressure independently of operation of the master cylinder; and a control section including: a first controller for controlling the booster; and a second controller for controlling the pressure regulator. The control section detects that at least one of the booster and the first controller is in a state of malfunction; selects one of backup modes according to the state of malfunction, wherein the backup modes restrict operation of at least one of the booster and the pressure regulator in different manners; and controls the wheel cylinder pressure in the selected backup mode.
