    i. Erhalten eines Schwellenwerts (612, 613) der Drehzahl des Verbrennungsmotors, der sogenannte Einschaltschwellenwert;
    ii. Erhalten der Drehzahl des Motors;
    iii. wenn die Drehzahl unter den Einschaltschwellenwert (612, 613) sinkt, Betätigen des Hauptaktuators (220) und des Hilfsaktuators, um das Ritzel (160) der Anlassvorrichtung mit der Kurbelwelle des Verbrennungsmotors (290) in Drehung zu verbinden;
    iv. Deaktivieren des Hauptaktuators und des Hilsaktuators, wenn der Verbrennungsmotor im Stillstand ist,
    v. Erhalten eines Befehls zum Starten des Verbrennungsmotors,
    vi. Einschalten des Hauptaktuators, um den Elektromotor (150) zu bestromen, der das Ritzel (160) der Anlassvorrichtung in Drehung versetzt; und dann
    vii. Ausschalten (604) des Hauptaktuators, wenn der Verbrennungsmotor eine bestimmte Drehzahl (611) erreicht.
  9. Verfahren nach Anspruch 8, wobei dem Verbrennungsmotor ein Befehl zum Anhalten vor dem Schritt iii) gegeben wird, der Einschaltschwellenwert (613) auf 50 Umdrehungen/Minute festgelegt wird.
  10. Verfahren nach Anspruch 9 oder 8, das einen Anlasser nach Anspruch 7 einsetzt, wenn ein Befehl zum Starten vor dem Schritt iv angefordert wird, wobei das Verfahren die Schritte iii, iv, v und vi durch die Schritte ersetzt, die in Folgendem bestehen:
    wenn die Drehzahl unter dem Einschaltschwellenwert (612, 613) liegt, Betätigen des Hauptaktuators (220) und des Hilfsaktuators (240), um das Ritzel (160) der Anlassvorrichtung mit der Kurbelwelle des Verbrennungsmotors (290) in Drehung zu verbinden; und dann Ausschalten des Hilfsaktuators, um den Elektromotor (150) zu bestromen und das Ritzel (160) der Anlassvorrichtung in Drehung zu versetzten, wobei das Ritzel (160) in Eingriffsposition bleibt;
    wenn die Drehzahl über dem Einschaltschwellenwert liegt, Betätigen des Hauptaktuators (220), um das Ritzel (160) der Anlassvorrichtung mit der Kurbelwelle des Verbrennungsmotors (290) in Drehung zu verbinden.
  11. Verfahren nach Anspruch 10, wobei, wenn der Schritt des Befehls zum Starten vor 300 Umdrehung/Minute angefordert wird, gewartet wird, dass der Verbrennungsmotor die 300 Umdrehungen/Minute erreicht, um den Hauptaktuator (220) zu betätigen.
