ABSTRACT:
The present invention is directed to a brake control system, which includes a first pressure circuit and a second pressure circuit for communicating a master cylinder with two sets of wheel cylinders, respectively. In each pressure circuit, a modulator is arranged to modulate the braking pressure in each wheel cylinder, a pressure pump is disposed to supply pressurized brake fluid to each wheel cylinder through each modulator, a normally open first valve is arranged to open or close a first passage for communicating the master cylinder with the modulator, and a normally closed second valve is arranged to open or close a second passage for communicating a reservoir directly with the inlet of each pump, or communicating the reservoir with it through the master cylinder. The pressurized brake fluid is supplied to each pressure circuit including the second valve at the inlet of the pump to perform an auxiliary pressurization. In the case where at least the second valve in the first pressure circuit opens the second passage, and the auxiliary pressurization is performed, the communication between the wheel cylinders in the second pressure circuit is blocked, when the brake pedal is not depressed, and the wheel cylinders in the second pressure circuit is communicated with the master cylinder, when the brake pedal is depressed.
