Method for preventing pressure fluctuations in hydraulic vehicle brake system used in motor vehicle, involves deriving over control during pre-control fluid, when pressure oscillation maxima exceed regulating pressure value

摘要

The method involves promoting the hydraulic pump in accordance with a predetermined desired pressure value, and a fluid pressure is built up. The analog regulating hydraulic valve is controlled (22). The pressure oscillation maxima fluid is derived in excess in the target pressure value. The over control is preceded by a pre-control, is derived (28) during the pre-control fluid, when the pressure oscillation maxima exceed a regulating pressure value and the regulating pressure value is reduced compared to the desired pressure value. An independent claim is included for a hydraulic vehicle brake system.
