  • Patent number: 8974013
    Abstract: A method for controlling a hydraulic braking system of a motor vehicle is provided. The method includes determining the vehicle speed and comparing the vehicle speed with a predefinable critical vehicle speed. If the vehicle speed lies below the critical vehicle speed, the method includes determining a required brake pressure or a brake pressure present in the braking system and comparing the brake pressure with a predefinable critical brake pressure. The method includes if the brake pressure lies below the critical brake pressure, blocking the buildup of a brake pressure in wheel brakes used for braking vehicle wheels of a vehicle rear axle.
