ABSTRACT:
A vehicle hydraulic brake control system includes a wheel brake for applying a hydraulic braking force to a wheel in response to a hydraulic pressure supplied to the wheel brake, a reservoir is which is stored brake fluid under the atmospheric pressure, a main hydraulic pressure source fluidly connected to the reservoir for generating a high hydraulic pressure in response to a force applied to an operating member of the vehicle, and an auxiliary hydraulic pressure source fluidly connected to the reservoir for generating another high hydraulic pressure. A control valve is fluidly connected to the main hydraulic pressure source, the auxiliary hydraulic pressure source, the wheel brake, and the reservoir for establishing a supply and drain of brake fluid under pressure to the wheel brake from either the main hydraulic pressure source or the auxiliary hydraulic pressure source. A fluid flow control device is provided in a passage connecting the auxiliary pressure source to a control valve to adjust the hydraulic pressure from the auxiliary pressure source to the control valve in two steps. When hydraulic pressure is supplied from the auxiliary pressure source to the wheel brake via the control valve, an increase rate of the hydraulic pressure in the wheel brake can be made quickly or slowly without operating the control valve on high cycles.
