ABSTRACT:
The invention is directed to a brake pressure control system which includes a brake pedal, a wheel brake operatively mounted on a wheel, and a pressure generator which generates a first brake pressure of a first pressure characteristic according to a stroke of the brake pedal, and which generates a second brake pressure of a second pressure characteristic according to the stroke of the brake pedal. The pressure generator is adapted to generate the second brake pressure to be higher than the first brake pressure, with a smaller stroke of the brake pedal than the stroke of the brake pedal for generating the first brake pressure. The system further includes a detector for detecting an emergency brake operation of the brake pedal, and a pressure selecting device which selects one of the first brake pressure and the second brake pressure to be supplied into the wheel brake. The pressure selecting device is adapted to select the second brake pressure when the detector detects the emergency brake operation of the brake pedal.
