Abstract (en)

The device has an electrical machine (12) acting as a starter and generator, an inverter (14) for converting the current produced or required by the machine and a control unit (30) for controlling the operation of the unit containing the machine and inverter depending on input signals. The control unit can be activated at intervals when the vehicle is not being operated. An additional controller (40) activates or deactivates the inverter depending on motor vehicle operating information.

Abstract (de)

Die Erfindung betrifft eine Vorrichtung zur Überwachung einer Starteinrichtung in einem Kraftfahrzeug mit einer als Anlasser und Generator dienenden elektrischen Maschine, einem Wechselrichter, zum Wandeln des in der elektrischen Maschine erzeugten oder benötigten Stromes, und einer Steuereinheit zum Steuern des Betriebs der aus der elektrischen Maschine und dem Wechselrichter bestehenden Einheit in Abhängigkeit von Eingangssignalen, wobei die Steuereinheit auch bei nicht in Betrieb befindlichem Fahrzeug in zeitlichen Abständen aktivierbar ist. Um ein unbeabsichtigtes Losfahren eines Fahrzeug zu verhindern, wird vorgeschlagen, eine zusätzliche Steuerung zu verwenden, die den Wechselrichter in Abhängigkeit von Fahrzeugbetriebsinformationen aktiviert oder deaktiviert. <IMAGE>
