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.

A brake apparatus is provided that can make a ratio between a front wheel braking force and a rear wheel braking force that is actually generated into an arbitrary ratio. This brake apparatus includes a pedal operation detection section that detects a pedal stroke or a brake pedal force produced by a brake pedal operation; a brake caliper that is provided in each wheel of a vehicle and that generates a caliper force that is in accordance with a detection value of the pedal operation detection section; a load estimation section that estimates a load of each of the wheels; and a force generation section that, after judging that braking is performed in a state in which a load difference exists between left and right wheels of the vehicle based on a value that is estimated by the load estimation section, even if the pedal operation detection section detects a pedal stroke or a brake pedal force that is the same as for the braking at a time of judging or for braking prior to the judging, generates a caliper force that is different to the caliper force before the judgment.

A brake control system includes a master cylinder to produce a master cylinder pressure, a brake booster to assist the master cylinder, a first control unit to control the booster, a hydraulic modulator to supply a wheel cylinder pressure to a wheel cylinder, and a second control unit to control the hydraulic modulator. The hydraulic modulator includes a pressure source, such as a pump, to increase the wheel cylinder pressure. The first and second control units are connected together by a communication line. The brake control system may further include a boost condition transmitting section to transmit, through the communicating line, a condition of a boost system formed by the brake booster and the first control unit.
