Abstract

Zum Erkennen eines Defekts oder Ausfalls eines Druckluftverbraucherkreises in einer Druckluftanlage für Fahrzeuge wird der Druck in den Druckluftverbraucherkreisen (26-38) laufend gemessen und in einer elektronischen Steuereinheit (84) ausgewertet, die die Druckluftverbraucherkreise kurzzeitig absperrt, während der Absperrzeit die Druckwerte misst und/oder Druckgradienten ermittelt und die Druckwerte und/oder die ermittelten Druckgradienten jeweils mit einem Schwellwert vergleicht, defekte Kreise ermittelt und als defekt erkannte Kreise endgültig absperrt, wenn der Schwellwert unterschritten wird.To detect a defect or failure of a compressed air consumer circuit in a compressed air system for vehicles, the pressure in the compressed air consumer circuits (26-38) is continuously measured and evaluated in an electronic control unit (84), which temporarily shuts off the compressed air consumer circuits, while the shut-off time measures the pressure values and / / or pressure gradient is determined and the pressure values and / or the determined pressure gradients in each case compared with a threshold value, determines defective circles and finally detects as defective detected circuits when the threshold value is reached.
