Abstract

Die vorliegende Erfindung betrifft eine Steuervorrichtung für ein VCR-Pleuel (6.1, 6.2, 6.3), das mittels einer Ansteuerschaltung (25.1) betätigbar ist. Ein solches VCR-Pleuel (6.1, 6.2, 6.3) soll einen sicheren Betrieb ermöglichen. Hierzu ist eine Detektionseinrichtung (42) zum Ermitteln eines Defekts der Ansteuerschaltung (25.1) vorgesehen. Des Weiteren bezieht sich die Erfindung auf ein entsprechend zugehöriges Verfahren zum Betreiben einer Ansteuerschaltung (25.1) eines VCR-Pleuels (6.1, 6.2, 6.3) eines Verbrennungsmotors.
