A device for controlling the brake pressure in a hydraulic brake system with the aid of a pressure-limiting valve that limits the brake pressure to a predefined threshold value, and to that end is driven by an electronic device in accordance with a valve characteristic curve. The setting accuracy can be improved considerably if an estimating unit for estimating the brake pressure, a sensor system for measuring the brake pressure, a unit for determining a pressure difference between the measured brake pressure and the estimated brake pressure, as well as a controller unit which drives the pressure-limiting valve as a function of the pressure difference are provided.
