Abstract:
In order to provide a hydraulic brake system of a motor vehicle that damps noises that would be produced under a vehicle running support brake control and damps uncomfortable feeling that would be applied to a driver when a brake pedal stroke takes place, there is proposed a brake fluid pressure control system in which a fluid pressure required by a selected brake cylinder of a road wheel is calculated based on a behavior of the motor vehicle, and for obtaining the required fluid pressure required by the selected brake cylinder, an upstream side brake fluid pressure controlling device is operated to increase the brake cylinder fluid pressure to a given pressure and thereafter a downstream side brake fluid pressure controlling device is operated to further increase the brake cylinder fluid pressure.
