Abstract (en)
[origin: WO2022089835A1] In order to test a function in a pressure generating module (2) of a hydraulic externally powered vehicle brake system (1), a brake pressure is generated by an externally powered brake pressure generator (4), and a pressure regulating module (3) is then hydraulically separated from the pressure generating module (2) by closing connection valves (21) or hydraulic wheel brakes (22) are hydraulically separated from the pressure generating module by closing inlet valves (23) so that no brake fluid flows into the wheel brakes (22) during the function test, which would reduce the brake pressure in the pressure generating module (2) and negatively affect or prevent the function test.
