Durch die Elektromaschine kann das Fahrzeug im Bereich geringer Leistungsanforderung rein elektrisch angetrieben werden und ermöglicht somit einen Betrieb des Verbrennungsmotors unter Berücksichtigung des Ladungszustands eines elektrischen Energiespeichers erst ab einer definierbaren verbrauchsgünstigeren Leistungsgrenze. Wobei durch die Elektromaschine im generatorischen Betrieb auch elektrische Energie in den elektrischen Energiespeicher eingespeist werden kann.By The electric machine can power the vehicle in the low power requirement range be driven purely electrically and thus allows operation of the internal combustion engine under consideration of the state of charge of an electrical energy storage only from a definable more fuel-efficient Power limit. Whereby by the electric machine in the generator Operation also electrical energy in the electrical energy storage can be fed.
Der direktstartfähige Verbrennungsmotor wirkt sich besonders günstig auf einen Start-Stopp-Betrieb aus, da dieser nicht durch eine elektrische Maschine gestartet werden muss, also beispielsweise nicht eine Kupplung zwischen Verbrennungsmotor und Elektromaschine zum Starten des Verbrennungsmotors geschlossen werden muss.Of the directly bootable Combustion engine has a particularly favorable effect on a start-stop operation because they are not started by an electric machine must, so for example, not a clutch between internal combustion engine and electric machine for starting the internal combustion engine closed must become.
Insbesondere kann bei einem Wechsel von einem rein elektrischen Antrieb ohne Zugkraftunterbrechung in einen Betriebsmodus mit rein verbrennungsmotorischem Antrieb geschaltet werden, wobei der Verbrennungsmotor zuvor selbsttätig gestartet wird.Especially Can without a change of a purely electric drive Traction interruption in an operating mode with purely internal combustion engine Drive are switched, the internal combustion engine is previously started automatically.
