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.
Claims15
A method for operating a hydraulic brake system of a motor vehicle having a brake booster and a hydraulic brake boost comprising:
- detecting a brake pressure;
- estimating an underpressure prevailing in an underpressure chamber of the brake booster based on the detected brake pressure and an actuation of the hydraulic brake boost;
- and
- controlling the hydraulic brake boost based on the estimated underpressure.
A method for operating a hydraulic brake system comprising:
- detecting a brake pressure;
- determining an estimating underpressure;
- upon actuation of a hydraulic brake boost determining a brake pedal travel;
- and
- determining a corrected underpressure based on said estimated underpressure and said brake pedal travel.
