Abstract (en)

[origin: WO2012084308A1] The invention relates to a method for controlling the wheel brake pressures in wheel brake cylinders (3) in a hydraulic vehicle braking system (1). The invention proposes to connect the wheel brake cylinders (3) via wheel valves (10) to a piston pump (4), the pistons (8) of which are double-action pistons, and the two piston sides are connectable by means of pump valves (11). In order to increase the wheel brake pressure, the wheel valves (10) are opened during a delivery stroke of the piston pump (4) and the pump valves (11) are closed, and the wheel valves (10) are closed and the pump valves (11) opened during a suction stroke. In order to reduce the wheel brake pressures, the valves (10, 11) are controlled in reverse.
