Abstract

Es werden eine Vorrichtung und ein Verfahren zur Überwachung eines piezoelektrischen Aktors zur Steuerung eines Injektors beschrieben. Es wird eine Kennlinie des Aktors ermittelt. Die ermittelte Kennlinie wird mit einer erwarteten Kennlinie verglichen. Bei einer Abweichung der ermittelten Kennlinie von der erwarteten Kennlinie wird ein Fehler des Injektors erkannt.
