Description
Claims (6)
einem für ein Rad (5) eines Fahrzeugs (1) bestimmten Schwingungsdämpfer (M1),
einem Detektor (M2), der eine Dämpfungskraft-Änderungsrate (V) des Schwingungsdämpfers (M1) ermittelt,
einer Straßenzustand-Beurteilungseinrichtung (M5), die aus der Dämpfungskraft-Änderungsrate (V) beurteilt, ob eine von dem Fahrzeug (1) befahrene Straßenoberfläche uneben ist,
einem mit dem Schwingungsdämpfer (M1) und dem Detektor (M2) zusammenwirkenden Dämpfungsregler (M3), der die Einstellung der Dämpfung auf der Grundlage einer Vergleichsbeziehung zwischen der Dämpfungskraft-Änderungsrate (V) und einem Einstell-Bezugswert (Vref) für eine Zeit (Ta) auf eine erste weiche Stufe bringt,
einer Dämpfungshalteeinrichtung (M4), die mit dem Schwingungsdämpfer (M1) und dem Dämpfungsregler (M3) zusammenwirkt und die Einstellung der Dämpfung auf der ersten weichen Stufe für eine Haltezeit (TH) und damit so lange hält, wie einerseits innerhalb der Zeit (Ta) weitere Überschreitungen des Einstell-Bezugswertes (Vref) erfolgen und andererseits eine zusätzliche vorbestimmte Zeit (Tbshrt) noch nicht abgelaufen ist, und
einer mit der Dämpfungshalteeinrichtung (M4) und der Straßenzustands-Beurteilungseinrichtung (M5) zusammenwirkenden Haltezeit-Korrektureinrichtung (M6), die die der Dämpfungshalteeinrichtung (M4) zuzuführende Haltezeit (TH) durch Veränderung der vorbestimmten Zeit (Tbshrt) auf eine Zeit (Tblong) verlängert, wenn die Straßenzustand-Beurteilungseinrichtung (M5) eine unebene Straßenoberfläche erkennt.
eine Frequenz (N) berechnet, die die Anzahl der Ereignisse wiedergibt, bei der die Dämpfungskraft-Änderungsrate (V) einen Lern-Bezugswert (VrefG), der kleiner ist als der Einstell-Bezugswert (Vref) in einer vorbestimmten Zeitdauer überschreitet, und
auf der Grundlage der berechneten Frequenz (N) entscheidet, ob die Straßenoberfläche uneben ist.
einen Mittelwert aus einer Vielzahl von Frequenzen (N) berechnet, von denen jede in einer vorbestimmten Zeitdauer erhalten wird, und eine Durchschnittsfrequenz (Navr) abgibt, und
die Durchschnittsfrequenz mit einer vorbestimmten Schwellenfrequenz (Nst) vergleicht und ein Vergleichsergebnis abgibt, das anzeigt, ob die Straßenoberfläche uneben ist.
