Method for identifying a failure of a brake circuit system in a vehicle and a brake system using such a method

摘要

The method involves determining whether a fluid pressure loss in the brake circuit is present. The fluid connection to a hydraulic unit and to the inlet valves (60,70) of to-be braked wheels of the vehicle are closed upon detection of a pressure loss so that a closed fluid system is generated. The generation of a pressure build-up in the closed fluid system is tried by a volume conveying unit. The generation of pressure build-up in the closed fluid system is ascertained. An independent claim is included for a brake system of a vehicle.
