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 relates to a hybrid drive system for a motor vehicle with an internal combustion engine and an electric machine, which communicate with each other 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 Beispielsweise geht aus

In der unveröffentlichten
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 goal pursued by the hybrid drive system according to the invention is to produce a cost-effective drive concept based on the lower edge of the customer requirement, in which the demands on the prior art are further reduced to the electric machine and also the electric machine itself Two-speed circuit makes 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 a motor and an electric machine is proposed, which drively acting on a differential, wherein motor and electric machine are connected to each other via a planetary gear and a further gear unit. The motor is operable in a narrow speed range and is preferably used for charging a battery connected to the electric machine, wherein the planetary gear and the further gear unit preferably align the drive load on the electric machine and the transmission can be used both for the internal combustion engine and for the electric machine is. By operating the engine in a speed range, a simple design of the engine is possible. A potentially usable internal combustion engine can dispense with complex control and be designed smaller in weight and space. To optimize costs and emissions, the operation of the internal combustion engine is provided only in one or a few defined rotational speeds, only the load is varied. This also less common engine concepts come into question. Alternative engines such as a gas turbine can be used in the inventive concept.
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 the smallest possible storage battery is used during driving, which is loaded as often as possible from the internal combustion engine and therefore does not have to represent a large energy storage for the electric 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. Advantageously, the drive system uses only a single electric machine and thus only a power electronics, wherein the electric machine for driving the motor vehicle, as a generator and as a starter machine is used.
Vorteilhafterweise verbindet das Getriebe Elektro- und Verbrennungsmotor synergetisch. Das Getriebe ist so gestaltet, dass bei möglichst geringem Aufwand möglichst viele Funktionen bereitgestellt werden.Advantageously, the transmission combines electric and combustion engine synergistically. The transmission is designed so 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 „Segelns” 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 provision of the different functions is achieved by a very simple power-shiftable two-stage transmission, which has not previously been used by its limitations. Such a transmission can transmit torque and force only in one direction, as there are freewheels. In the inventive concept, the potential disadvantage is advantageously used to use the motor for charging the battery during "sailing". It is advantageously provided for the individual functions: a planetary gear for starting the vehicle, the switchable planetary gear is used as a replacement of the clutch and thus the vehicle is also used in a completely deflated battery. Just this feature allows starting without conventional clutch with an internal combustion engine, which is operated at an optimal speed and a dead battery. Furthermore, the transmission includes a freewheeling function, in which the battery is charged without a drive of the vehicle takes place ("sailing"). Another function of the transmission switches a mode switch for combined or pure electric driving and the recovery of energy or charging the battery at standstill of the vehicle.
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 building costs for positive or frictional clutches was paid particular attention to simplicity: In one embodiment, all four clutches are actuated by only three actuators.
Beschreibung der ErfindungDescription of the invention
Die Erfindung wird nachfolgend beispielhaft unter Bezugnahme auf die beigefügten Zeichnungen beschrieben.The invention will now be described by way of example with reference to the accompanying drawings.
Im Folgenden sind bestimmte mögliche Ausführungsformen dargestellt. Alle aufgeführten Prinzipien sind aber jeweils alleine bzw. in allen möglichen Kombination untereinander ebenfalls denkbar. Die Auswahl ist nach einer genaueren Untersuchung der technischen bzw. wirtschaftlichen Eignung anwendungsspezifisch zu treffen.In the following certain possible embodiments are shown. However, all listed principles are also conceivable alone or in any possible combination with one another. The selection must be made according to the specific application for a more detailed examination of the technical or economic suitability.
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.The battery used conceptually does not have a large storage capacity, a cost-effective solution sees only a battery with an energy storage of 5 to 15 kWh, which is well below the energy requirement 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 Table 1 describes the circuit states of the four clutches for the different modes of operation. Table 1
Für den Start des Verbrennungsmotors mit Hilfe der elektrischen Maschine sind die Kupplungen C1, C2 geöffnet und Kupplungen C3 und C4 sind dagegen geschlossen. In dieser Getriebekonstellation mit den offenen Kupplungen C1 und C2 ermöglicht die elektrische Maschine
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 C1 und C4 zeigt man einen Zustand des Getriebes und der Kupplungen, der dem Anfahren des Fahrzeugs entspricht. Beim Anfahren arbeitet das erfindungsgemäße Getriebe hinsichtlich der konstanten Drehzahl des Verbrennungsmotors wie ein stufenloses Getriebe (CVT). Beide Energiequellen, der Verbrennungsmotor
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 elektrische Maschine geladen wir und der Verbrennungsmotor in einem optimalen Drehzahlbereich läuft.Both machines work together because they are firmly connected to each other via a branch. The performance of the machines corresponds to a performance mix and is freely selectable. If the internal combustion engine has only a low demand on the power, with a load point increase of the internal combustion engine, the specific consumption of the entire system can be improved, with the electric machine charging and the internal combustion engine running at an optimal speed range.
Die Schaltungsstellung mit geschlossenen Kupplungen C1 und C4 wird auch zum Fahren mit dem Verbrennungsmotor verwendet, wenn die Batterie leer ist und die elektrische Maschine
Durch Schließen der Kupplung C2 und Öffnen der C1 wird vom ersten in den zweiten Gang rein elektrischer Fahrweise geschaltet.By closing the clutch C2 and opening the C1 is switched from the first to the second gear purely electrical driving.
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 C1 und C2 zu verwenden. Für die Positionen C3 und C4 werden weiterhin Reibkupplungen eingesetzt, da die Anforderungen an dieser Stelle höher sind und sich die Reibkupplungen dafür besser eignen.The previously illustrated embodiments use friction clutches to represent the various functions. Since the system must be cost-optimized, it is also possible to use dog clutches instead of friction clutches at least at positions C1 and C2. For the positions C3 and C4 friction clutches are still used because the requirements are higher at this point and the friction clutches are better suited.
Die nachstehende Tabelle fasst die Fahrbetriebsmodi zusammen. Tabelle 2 The table below summarizes the driving modes. Table 2
