Blocking rear brake pressure, during reversing, when the vehicle speed is below a predetermined level

摘要

The invention relates to a method for controlling a hydraulic braking system of a motor vehicle during reversing, which comprises the following steps: 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, 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, wherein if the brake pressure lies below the critical brake pressure blocking the build-up of a brake pressure in the rear wheel brakes. The invention reduces brake noise under gentle braking when slowly reversing. The critical vehicle speed is preferably below 20km/h in particular below 5km/h. The critical brake pressure is preferably below 20% in particular below 5% of a maximum brake pressure under full braking.
