Description
Stand der TechnikState of the art
Bei
bisher entwickelten Hybridantrieben werden zwei Entwicklungsrichtungen
verfolgt. Zum einen wird ein Hybridantrieb entwickelt, der einen
Parallelhybrid darstellt, ferner wird ein Hybridtypus entwickelt,
der als leistungsverzweigender Hybridantrieb bezeichnet wird. Die
Lösung gemäß
Daraus resultiert der Nachteil, dass mit einem Hybridantriebskonzept darstellbare Funktionen, wie zum Beispiel der Rekuperationsbetrieb, d. h. das Einspeisen zusätzlicher Energie durch den elektrischen Antrieb in eine Hochspannungsbatterie, sowie ein Boostbetrieb, d. h. ein Antrieb des hybridgetriebenen Kraftfahrzeuges durch Verbrennungskraftmaschine und gleichzeitig zugeschaltetem mindestens einen elektrischen Antrieb, begrenzt darstellbar sind. Bei Hybridantrieben, die mindestens eine elektrische Maschine neben der Verbrennungskraftmaschine umfassen, ist zumindest ein elektrischer Energiespeicher, sei es eine Hochspannungsbatterie oder seien es Kondensatoren (Supercaps), erforderlich. Diese elektrischen Energiespeicher, seien es eine Hochspannungsbatterie oder seien es eine Anzahl von Kondensatoren (Supercaps), sind in der Regel in der erforderlichen Baugröße sehr teuer und derzeit noch nicht lebensdauerfest, bezogen auf die vorhersehbare Fahrzeuglebensdauer. Des Weiteren benötigt der elektrische Energiespeicher einen relativ großen Einbauraum und beeinträchtigt das Fahrzeuggewicht eines mit Hybridantrieb ausgestatteten Fahrzeugs negativ, was wiederum Auswirkungen auf den Kraftstoffverbrauch nach sich zieht, da die ein relativ hohes Eigengewicht aufweisenden Komponenten des Hybridantriebes im Betriebsmodus motorisches Fahren mitbewegt werden müssen.from that results in the disadvantage that can be displayed with a hybrid drive concept Functions, such as recuperation, d. H. the feeding additional energy through the electric drive in a high voltage battery, as well as a boost operation, d. H. a drive the hybrid-powered motor vehicle by internal combustion engine and at the same time switched on at least one electric drive, are limited representable. In hybrid drives, the at least one include electrical machine in addition to the internal combustion engine, is at least an electrical energy storage, be it a high voltage battery or be it capacitors (supercaps). This electrical Energy storage, be it a high voltage battery or There are a number of capacitors (supercaps) that are usually in the required size very expensive and currently not life-long, based on the predictable Life of the vehicle. Furthermore, the electric needed Energy storage a relatively large installation space and impaired the vehicle weight of a vehicle equipped with hybrid drive negative, which in turn affects fuel economy after it pulls, since the relatively high dead weight components of the Hybrid drive in the operating mode motor driving be moved have to.
Innerhalb Antriebssträngen von Fahrzeugen, seien sie mit Hybridantrieb, seien sie konventionell aufgebaut, eingesetzte automatisierte Schaltgetriebe weisen während der Schaltvorgänge spürbare, d. h. für den Fahrer wahrnehmbare Momenteneinbrüche auf.Within Powertrains of vehicles, whether with hybrid drive, they are conventionally constructed, used automated manual transmission noticeable during switching operations, d. H. for the driver perceptible moments burglaries.

Dieses wird entweder durch das erstgenannte Hydraulikaggregat oder durch den im Hydraulikspeicher vorgehaltenen Druck versorgt. Des Weiteren kann über das zweite Hydraulikaggregat eine Rekuperation von kinetischer Energie sowie ein Zwischenspeicher der hydraulischen Energie im Speicher erfolgen. Über das erstgenannte Hydraulikaggregat kann ein Start der Verbrennungskraftmaschine erfolgen. Unter Nutzung des in den Antriebsstrang integrierten zweiten Hydraulikaggregates lässt sich ein hydraulischer Fahrbetrieb, insbesondere ein hydraulisches Anfahren des Kraftfahrzeuges, implementieren.The Functions that are within the invention proposed Powertrain be implemented for a motor vehicle may include, for example, a compensation of torque fluctuations, which usually when making shifts on automated manual transmission occur and through the second hydraulic unit be compensated. This is either by the former Hydraulic unit or held by the stored in the hydraulic accumulator Pressure supplied. Furthermore, via the second hydraulic unit a recuperation of kinetic energy and a cache the hydraulic energy is stored in the tank. About the The former hydraulic unit can be a start of the internal combustion engine respectively. Using the second integrated into the drive train Hydraulic power units can be a hydraulic driving, in particular a hydraulic starting of the motor vehicle, implement.
Über das im Hydraulikspeicher bevorratete Hydraulikfluid und den dort erzeugten Druck können Nebenaggregate, wie zum Beispiel eine hydraulische Lenkung, Bremskraftverstärker, ABS, ESP, Generator, Klimakompressoren beziehungsweise Einspritzsysteme des Kraftfahrzeuges, über eine zentral erzeugte und vorgehaltene hydraulische Energie versorgt werden.about the stored in the hydraulic accumulator hydraulic fluid and the there generated pressure can create ancillaries, such as a hydraulic steering, brake booster, ABS, ESP, Generator, air conditioning compressors or injection systems of the Motor vehicle, via a centrally generated and held hydraulic energy to be supplied.
Des Weiteren kann über das mindestens eine im Antriebsstrang implementierte hydraulische Aggregat eine Start/Stopp-Funktion der Verbrennungskraftmaschine realisiert werden.
