Abstract

Die vorliegende Erfindung beschreibt einen Gaskonzentrationssensor bestehend aus: einem Schallsender, einem Schallempfänger, einer Regelvorrichtung, mit der ein Phasenversatz zwischen dem von dem Schallsender ausgesendeten Schallsignal und einem von dem Schallempfänger empfangenen Schallsignal auf einem vorgebbaren Phasenversatz regelbar ist, wobei eine Änderung einer Zusammensetzung eines Gasgemischs auf Grund einer Frequenzänderung des Schallsignals gegenüber einer Frequenz eines Referenzschallsignals mittels einer Auswerteeinheit bestimmbar ist. Weiterhin beschreibt die Erfindung ein Kraftfahrzeug mit dem erfindungsgemäßen Gaskonzentrationssensor sowie ein Gaskonzentrationsmessverfahren, das den erfindungsgemäßen Gaskonzentrationssensor verwendet.
