Filed: 1981-01-12
Granted: 1985-09-19
Abstract: In einer Vorrichtung zur Bestimmung der Änderungsgröße der Radumdrehungsgeschwindigkeit an einem Kraftfahrzeug gibt ein Fühler (28) laufend ein Fühler-Impulssignal ab, dessen Frequenz der ermittelten Geschwindigkeit proportional ist. Als Zeiteinheit für die Geschwindigkeitsmessung dient die Frequenz eines von einem Taktsignalgenerator (20) abgegebenen Taktsignals. Alle Daten in bezug auf eine gemessene Impulslänge der Fühlersignale werden in einem Speicher (30) gespeichert, und auf der Grundlage der Speicherwerte berechnet eine Recheneinheit (50) die Änderungsgröße ( α) der Geschwindigkeit. Wenn die Vorrichtung eine Abweichung in der Frequenz des Fühlersignals erkennt, wird ein Befehl zur Erhöhung der Anzahl von zu einer Gruppe zusammenzufassenden Impulsen erzeugt, deren Dauer wie eine Impulslänge gemessen wird, wenn eine Frequenzabweichung des Fühlersignals nicht feststellbar oder kleiner als ein vorgegebener Wert ist. Die Vorrichtung erhöht zyklisch die zusammenzufassende Impulsanzahl bis eine Fühlersignal-Frequenzabweichung festgestellt und größer als der Vorgabewert ist, oder bis die Anzahl der Impulse in der Gruppe einen gegebenen Maximalwert erreicht hat.
