A method and system for operating a motor vehicle brake system, including several wheel brakes, an electrically controllable pressure supply device, dispenses a pressure medium volume for actuating the brakes, and an analogized or analog-controlled inlet valve, arranged in each wheel brake between the pressure supply device and wheel brake, for adjusting wheel-individual brake pressures. A check valve is connected in parallel to each inlet valve. At the start of a wheel-individual brake pressure control, all inlet valves are closed, and a pressure build-up is carried out in a predetermined group of one or more wheel brakes by displacing a pressure medium volume into the predetermined group of wheel brakes by the pressure supply device. Each inlet valve of the predetermined group is controlled such that the inlet valve is overflowed, wherein each inlet valve of the remaining wheel brakes is controlled such that the inlet valve remains closed. |
