Description
Die Erfindung geht aus von einem hybriden Antriebssystem für ein Kraftfahrzeug mit einem Verbrennungsmotor und einer elektrischen Maschine, die über ein Getriebe miteinander in Verbindung stehen.The invention is based on a hybrid drive system for a motor vehicle with an internal combustion engine and an electrical machine, which are connected to one another via a transmission.
Stand der TechnikState of the art
Bisher gibt es viele Hybridkonzepte, die alle ihre spezifische Vor- und Nachteile haben. Meist sind diese Systeme aufwendig konstruiert oder weisen nur in bestimmten Betriebspunkten Vorteile auf im Vergleich zu herkömmlichen Antriebssträngen. Oft sind diese Konzepte nur für den Verbrauchszyklus optimiert. Im normalen Straßenbetrieb dagegen sind die Vorteile weitaus geringer. In diesen Konzepten wurden bereits automatische und automatisierte Getriebe vorgesehen

Die
Das Ziel, welches mit dem erfindungsgemäßen hybriden Antriebssystem verfolgt wird, ist, ein kostengünstiges und am unteren Rand des Kundenbedarfes angesiedeltes Antriebskonzept herzustellen, bei dem die Anforderungen gegenüber dem Stand der Technik an die elektrische Maschine weiter reduziert ist und auch die elektrische Maschine für sich eine Zwei-Gang-Schaltung nutzbar macht.The aim pursued with the hybrid drive system according to the invention is to produce a cost-effective drive concept that is at the lower end of customer requirements and in which the requirements for the electrical machine are further reduced compared to the state of the art, and the electrical machine itself is one Makes two-speed shift usable.
Vorteilhafterweise wird ein hybride Antriebssystem für ein Kraftfahrzeug mit einem Motor und einer elektrischen Maschine vorgeschlagen, die antriebsmäßig auf ein Differential einwirken, wobei Motor und elektrische Maschine über ein Planetengetriebe und eine weitere Getriebeeinheit miteinander verbunden sind. Der Motor ist in einem engen Drehzahlbereich betreibbar und dient bevorzugt zum Laden einer an die elektrische Maschine angeschlossenen Batterie, wobei das Planetengetriebe und die weitere Getriebeeinheit die Antriebslast bevorzugt auf die elektrische Maschine ausrichten und das Getriebe sowohl für den Verbrennungsmotor als auch für die elektrische Maschine einsetzbar ist.
Durch den Betrieb des Motors in einem Drehzahlbereich ist eine einfache Ausgestaltung des Motors möglich. Ein potentiell einsetzbarer Verbrennungsmotor kann auf komplexe Steuerung verzichten und kleiner im Gewicht und Bauraum ausgelegt sein. Zur Optimierung von Kosten und Emission ist der Betrieb des Verbrennungsmotors nur in einer bzw. wenigen definierten Drehzahl(en) vorgesehen, lediglich die Last wird variiert. Damit kommen auch bisher weniger gebräuchliche Motorenkonzepte in Frage. Auch alternative Motoren wie eine Gasturbine lassen sich im erfindungsgemäßen Konzept einsetzen.Advantageously, a hybrid drive system for a motor vehicle with an engine and an electrical machine is proposed which drive a differential, the engine and electrical machine being connected to one another via a planetary gear and a further gear unit. The motor can be operated in a narrow speed range and is preferably used to charge a battery connected to the electric machine, the planetary gear and the further gear unit preferably aligning the drive load with the electric machine and the gear being usable for both the internal combustion engine and the electric machine is.
By operating the motor in a speed range, a simple design of the motor is possible. A potentially usable internal combustion engine can dispense with complex control and can be designed to be smaller in weight and installation space. To optimize costs and emissions, the Internal combustion engine is only provided in one or a few defined speed (s), only the load is varied. This means that previously less common engine concepts come into question. Alternative motors such as a gas turbine can also be used in the concept according to the invention.
Vorteilhafterweise wird nur eine möglichst kleine Speicherbatterie im Fahrbetrieb einsetzt, die möglichst oft von der Verbrennungskraftmaschine geladen wird und daher keinen großen Energiespeicher für die elektrische Maschine darstellen muss.Advantageously, only a storage battery that is as small as possible is used during driving operation, which is charged as often as possible by the internal combustion engine and therefore does not have to represent a large energy store for the electrical machine.
Vorteilhafterweise verwendet das Antriebssystem nur eine einzige elektrische Maschine und damit nur eine Leistungselektronik, wobei die elektrische Maschine zum Antreiben des Kraftfahrzeugs, als Generator und als Startermaschine dient.The drive system advantageously uses only a single electrical machine and thus only power electronics, the electrical machine serving to drive the motor vehicle, as a generator and as a starter machine.
Vorteilhafterweise verbindet das Getriebe Elektro- und Verbrennungsmotor synergetisch. Das Getriebe ist so gestaltet, dass bei möglichst geringem Aufwand möglichst viele Funktionen bereitgestellt werden.The transmission advantageously combines the electric motor and the internal combustion engine in a synergetic manner. The transmission is designed in such a way that as many functions as possible are provided with the least possible effort.
Die Bereitstellung der unterschiedlichen Funktionen gelingt durch ein sehr einfaches lastschaltbares zweistufiges Getriebe, das bisher durch seine Limitierungen nicht eingesetzt wird. Ein solches Getriebe kann Drehmoment und Kraft nur in einer Richtung übertragen, da Freiläufe vorhanden sind. Im erfindungsgemäßen Konzept wird der potentielle Nachteil vorteilhaft eingesetzt, um während des „Segeins“ den Motor zum Laden der Batterie einzusetzen.
Dabei wird für die einzelnen Funktionen vorteilhafterweise vorgesehen:
- ein Planetengetriebe zum Anfahren des Fahrzeugs, wobei das durchschaltbare Planetengetriebe als Ersatz der Kupplung dient und somit das Fahrzeug auch bei einer völlig entleerten Batterie einsetzbar ist.
- Gerade diese Funktion ermöglicht das Anfahren ohne konventionelle Kupplung mit einem Verbrennungsmotor, der bei einer optimalen Drehzahl betrieben wird und einer leeren Batterie.
- Weiterhin enthält das Getriebe eine Freilauffunktion, in der die Batterie geladen wird, ohne dass ein Antrieb des Fahrzeugs erfolgt („Segeln“).
- Eine weitere Funktion des Getriebes schaltet einen Mode-Schalter für kombiniertes bzw. rein elektrisches Fahren sowie die Rückgewinnung von Energie oder das Laden der Batterie im Stillstand des Fahrzeugs.
The following is advantageously provided for the individual functions:
- a planetary gear for starting the vehicle, the shiftable planetary gear serving as a replacement for the clutch and thus the vehicle can also be used when the battery is completely empty.
- It is precisely this function that enables starting off without a conventional clutch with an internal combustion engine that is operated at an optimal speed and an empty battery.
- The transmission also has a freewheel function in which the battery is charged without the vehicle being propelled (“sailing”).
- Another function of the transmission is a mode switch for combined or purely electric driving as well as the recovery of energy or the charging of the battery when the vehicle is stationary.
Beim Bauaufwand für form- oder reibschlüssige Kupplungen wurde besonders auf Einfachheit geachtet: In einer Ausführungsform werden alle vier Kupplungen durch lediglich drei Aktuatoren betätigt.When it comes to the construction costs for form-locking or frictional-locking clutches, particular attention was paid to simplicity: In one embodiment, all four clutches are operated by just three actuators.

Das hybride Antriebssystem besteht aus zwei Hauptkomponenten, dem Verbrennungsmotor
Der Verbrennungsmotor
Die eingesetzte Batterie muss konzeptionell keine große Speicherkapazität aufweisen, eine kostengünstige Lösung sieht lediglich eine Batterie mit einer Energiespeicherung von 5 bis 15 kWh, was deutlich unter der Energieanforderung an ein bisheriges System, bei entsprechender Reichweite und Fahrzeugmasse liegt.Conceptually, the battery used does not have to have a large storage capacity, a cost-effective solution only provides a battery with energy storage of 5 to 15 kWh, which is significantly below the energy requirements of a previous system, with the appropriate range and vehicle mass.
Tabelle 1 beschreibt die Schaltungszustände der vier Kupplungen für die unterschiedlichen Betriebsmodi.
Tabelle 1
Für den Start des Verbrennungsmotors mit Hilfe der elektrischen Maschine sind die Kupplungen
Diese dargestellte Funktion wird nicht nur bei völligem Stillstand des Fahrzeuges aktiviert. Auch bei einfachem Rollen des Fahrzeuges ohne Last wird der Verbrennungsmotor aktiviert und lädt über den Generator, die elektrische Maschine
Schließt man die Kupplungen
Beide Maschinen arbeiten dabei zusammen, da sie über einen Zweig fest miteinander verbunden sind. Die Leistungen der Maschinen entsprechen einem Leistungsmix und sind dabei frei wählbar. Wenn für die Verbrennungskraftmaschine nur eine geringe Anforderung an die Leistung vorhanden ist, kann mit einer Lastpunktanhebung der Verbrennungskraftmaschine der spezifische Verbrauch des Gesamtsystems verbessert werden wobei die Batterie durch die elektrische Maschine geladen wird und der Verbrennungsmotor in einem optimalen Drehzahlbereich läuft.Both machines work together because they are firmly connected to one another via a branch. The performance of the machines corresponds to a performance mix and can be freely selected. If the internal combustion engine has only a low power requirement, the specific consumption of the overall system can be improved by increasing the load point of the internal combustion engine, the battery being charged by the electric machine and the internal combustion engine running in an optimal speed range.
Die Schaltungsstellung mit geschlossenen Kupplungen
Durch Schließen der Kupplung
Die bisher dargestellten Ausführungsformen verwenden Reibkupplungen um die verschiedenen Funktionen darzustellen. Da das System kostenoptimiert werden muss, ist es auch möglich Klauenkupplungen statt Reibkupplungen zumindest an den Positionen
Die nachstehende Tabelle fasst die Fahrbetriebsmodi zusammen.
