Pressure control with a pump

A method for controlling a brake system having a plurality of wheel brakes with associated inlet valves and outlet valves, and a hydraulic pump for conveying brake fluid to the plurality of wheel brakes, said method comprising:

• determining the wheel brake of the plurality of wheel brakes with the highest pressure demand and assigning the wheel brake with the highest pressure demand as Maxwheel and the other wheel brakes as the remaining wheel brakes;
• adjusting a setpoint pressure in the remaining wheel brakes by opening the inlet valve and closing the outlet valve until the setpoint pressure is reached, and closing the inlet valve when the setpoint is reached;
• and
• adjusting a setpoint pressure in the Maxwheel by opening the inlet valve and closing the outlet valve until the setpoint pressure is reached, and keeping open the inlet valve and pulsing the outlet valve when the setpoint is reached.

A hydraulic brake system for motor vehicles, comprising:

• a plurality of wheel brakes with associated inlet valves and outlet valves;
• a hydraulic pump for conveying brake fluid to the plurality of wheel brakes;
• and a control device configured to
• determine the wheel brake of the plurality of wheel brakes with the highest pressure demand and assigning the wheel brake with the highest pressure demand as Maxwheel and the other wheel brakes as the remaining wheel brakes,
• adjusting a setpoint pressure in the remaining wheel brakes by opening the inlet valve and closing the outlet valve until the setpoint pressure is reached, and closing the inlet valve when the setpoint is reached, and
• adjusting a setpoint pressure in the Maxwheel by opening the inlet valve and closing the outlet valve until the setpoint pressure is reached, and keeping open the inlet valve and pulsing the outlet valve when the setpoint is reached.
