Abstract

A method for operating a hydraulic brake system of a motor vehicle having a brake booster and a hydraulic brake boost wherein a brake pressure is detected and an underpressure, prevailing in an underpressure chamber of the brake booster is estimated on the basis of the detected brake pressure. The hydraulic brake boost controlled based on the estimated underpressure, with the estimated underpressure taking into account an actuation of the hydraulic brake boost.
