Abstract
System (2) zur Bremskreisausfallerkennung in einem Bremssystem mit zumindest einem Bremselement, aufweisend mindestens einen hydraulischen Bremskreislauf (4), eingerichtet zur Aktivierung zumindest eines Bremselementes (6), ein Drucksensorelement (8), eingerichtet zum Detektieren eines aktuellen Ist-Drucks im Bremskreislauf, einen Bremssignalgeber (10) und ein Positionssensorelement (14), eingerichtet, ein Positionssignal des Bremssignalgebers zu bestimmen, dadurch gekennzeichnet, dass aufgrund des Positionssignals ein aktueller Soll-Druck im Bremskreislauf bestimmbar und durch Vergleich des aktuellen Ist-Drucks mit dem aktuellen Soll-Druck ein Ausfall des Bremskreislaufes detektierbar ist.
