Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren zum Betrieb eines solchen Hybridantriebssystems vorzuschlagen, mit dem der Fahrzeugantrieb hinsichtlich Verbrauchsoptimierung und Komfortsteigerung verbessert werden kann.Of these, The present invention is based on the object, to propose a method of operating such a hybrid drive system, with the vehicle drive in terms of consumption optimization and Comfort increase can be improved.
Die
Lösung liegt in einem Verfahren zum Betrieb eines Hybridantriebssystems
mit einer Hauptantriebsmaschine – insbesondere einem Verbrennungsmotor – und
einer Zusatzantriebsmaschine – insbesondere einer elektrischen
Maschine – für ein Kraftfahrzeug, umfassend
ein
erstes Gangschaltteilgetriebe mit einer ersten Eingangswelle, die
mit einer Abtriebswelle koppelbar ist mittels einer ersten Gruppe
von Gangschaltzahnradpaaren, dessen Eingangswelle mit der ersten
Antriebsmaschine koppelbar ist,
ein zweites Gangschaltteilgetriebe
mit einer zweiten Eingangswelle, die mit der Abtriebswelle koppelbar ist
mittels einer zweiten Gruppe von Gangschaltzahnradpaaren, dessen
Eingangswelle mit der zweiten Antriebsmaschine antriebsverbunden
ist, das sich dadurch auszeichnet, daß bei acht darstellbaren Gangschaltzuständen
für die Hauptantriebsmaschine (1,1 Lang, 2 bis 7/...) zur
Vorwärtsfahrt und sieben darstellbaren Gangschaltzuständen
für die Zusatzantriebsmaschine zur Vorwärtsfahrt
(...../1 bis 7) zumindest zehn verschiedene Gangschaltzustände
im hybriden Antriebsmodus zur Vorwärtsfahrt dargestellt werden.
Vorzugsweise werden dabei mehr als zehn, insbesondere sogar mehr
als elf verschiedene Gangschaltzustände im hybriden Antriebsmodus
zur Vorwärtsfahrt dargestellt.The solution lies in a method for operating a hybrid drive system with a main drive machine - in particular an internal combustion engine - and an auxiliary drive machine - in particular an electric machine - for a motor vehicle, comprising
a first gearshift subgear having a first input shaft which is coupleable to an output shaft by means of a first group of gearshift gear pairs whose input shaft is coupleable to the first prime mover,
a second gearshift subgear having a second input shaft couplable to the output shaft by means of a second group of gearshift gear pairs whose input shaft is driveably connected to the second prime mover, characterized by eight gearshift states for the main propulsion engine (1,1 Lang, 2 to 7 / ...) for forward travel and seven displayable gearshift states for the auxiliary drive machine for forward travel (..... / 1 to 7) at least ten different gearshift states are represented in the hybrid drive mode for forward travel. Preferably, more than ten, in particular even more than eleven different gearshift states are displayed in the hybrid drive mode for forward travel.
Hierbei ist vorgesehen, daß im Betrieb mit beiden Antriebsmaschinen ohne Unterbrechung der Zugkraft geschaltet wird, indem ein Gangwechsel zwischen den Gangstufen für die beiden Antriebsmaschinen jeweils bei unterschiedlichen Fahrgeschwindigkeiten, gegebenenfalls abwechselnd erfolgt.in this connection is provided that in operation with both prime movers Without interrupting the traction is switched by a gear change between the gear ratios for the two prime movers each at different speeds, optionally alternately he follows.
Die Lösung liegt schließlich in einem Steuerungssystem für ein Hybridantriebssystem der genannten Art mit den oben benannten Funktionen.The Solution is finally in a control system for a hybrid drive system of the type mentioned with the above named functions.
Durch eine sinnvolle Reihenfolge des Öffnens und Schließens der Reibungskupplung des Verbrennungsmotors sowie eine daran angepaßte Reihenfolge der Betätigung der Schalteinheiten der verschiedenen Gänge ist ein zugkraftfreies Schalten zwischen den Gängen möglich. Entscheidend für diese Art der Betätigung ist, daß bei der erfindungsgemäßen Getriebeanordnung das zu schaltende Element (Schaltkupplung, Schalteinheit) stets abgetrennt werden kann, während wenigstens ein Antrieb, entweder die elektrische Maschine oder der Verbrennungsmotor, mit der Abtriebswelle in drehmomentübertragender Verbindung steht. Beim Schalten können die Drehzahlen an den zu schaltenden Elementen durch entsprechende Steuerung der elektrischen Maschine und des Verbrennungsmotors angeglichen, d. h. synchronisiert werden. Die Reibungskupplung des Verbrennungsmotors läßt ein schleifendes Zuschalten des Verbrennungsmotors zu. Die elektrische Maschine kann ebenfalls über eine Reibungskupplung ankoppelbar sein, deren Funktion aber im Rahmen der beanspruchten Verfahren nicht in Anspruch genommen wird.By a meaningful sequence of opening and closing the friction clutch of the engine and an adapted thereto sequence of actuation of the switching units of the various gears a traction-free switching between the gears is possible. Decisive for this type of operation is that in the transmission arrangement according to the invention, the element to be switched (clutch, switching unit) can always be separated, while at least one drive, either the electric machine or the Burn motor with the output shaft in torque-transmitting connection. When switching the rotational speeds of the elements to be switched can be adjusted by appropriate control of the electric machine and the internal combustion engine, ie synchronized. The friction clutch of the internal combustion engine allows a grinding connection of the internal combustion engine. The electric machine can also be coupled via a friction clutch, whose function is not claimed in the claimed method.
Aufgrund der gewählten Anordnung des Verbrennungsmotors und der elektrischen Maschine erfolgt bei Betrieb beider Antriebsmaschinen eine Drehmomentaddition.by virtue of the selected arrangement of the internal combustion engine and the electric machine takes place when operating both drive machines a torque addition.
Wie nachfolgend dargestellt, ist ein Anfahren mit der elektrischen Maschine sowie ein Generatorbetrieb der elektrischen Maschine im Rekuperations-Modus möglich.As shown below, is a startup with the electric machine and a generator operation of the electric machine in recuperation mode possible.
Weitere günstige Ausgestaltungen finden sich in den Unteransprüchen, auf die hier inhaltlich Bezug genommen wird.Further favorable refinements can be found in the subclaims, to which reference is made here.
Folgende
Wesensmerkmale und Vorteile des erfindungsgemäßen
Verfahrens werden nachstehend benannt:
Gangwechsel ohne Zugkraftunterbrechung,
d. h. mindest eine der Antriebsmaschinen kann bei der Betätigung
eines oder mehreren Schaltelemente weiterhin Drehmoment auf die
Abtriebswelle übertragen, allerdings ist diese Funktion
je nach Wahl der Übersetzung nicht bei allen möglichen
Schaltabfolgen gegeben;
rein elektrisches Fahren ist möglich;
Starten
des Verbrennungsmotors durch die elektrische Maschine ist möglich;
Starten
des Verbrennungsmotors während des rein elektrischen Fahrens
mit der elektrischen Maschine ist möglich, auch über
verschiedene Gänge;
aktive Synchronisation der Schaltvorgänge
ist möglich;
Boostbetrieb, d. h. zeitweiliges Zuschalten
der elektrischen Maschine ist möglich;
Rekuperation,
d. h. Rückgewinnung von Energie mittels der elektrischen
Maschine beim Abbremsen des Fahrzeugs ist möglich;
Klimakompressorbetrieb,
insbesondere zur Batteriekühlung, bei Stillstand des Fahrzeuges
ist möglich;
Erhalten der AMT-Funktionalität
(automated manual transmission) bei Ausfall der elektrischen Maschine (fail
safe);
guter Wirkungsgrad durch verbrauchsoptimierte Schaltstrategien
unter Nutzung des guten Wirkungsgrades eines konventionellen Schaltgetriebes
(Zahnradgetriebes) und damit Kraftstoffeinsparung ist möglich;
je
nach Wahl der Schaltelemente und der Reibungskupplung ist keine
Getriebehydraulik erforderlich;
Durch Verwendung einer insbesondere
elektrischen Feststellbremse oder elektrisch gesteuerten Eingriffs in
das Betriebssystem des Fahrzeugs kann sichergestellt werden, daß ein
Anfahren des Fahrzeugs am Hang aus der Schaltstellung 0-0 ohne ein
merkbares zurückrollen des Fahrzeugs möglich wird.
Das Steuerungssystem ist entsprechend auszulegen (Hillhold-Funktion).The following features and advantages of the method according to the invention are named below:
Gear change without interruption of traction, ie at least one of the prime movers can continue to transmit torque to the output shaft upon actuation of one or more switching elements, but this function is not given in all possible switching sequences depending on the choice of the translation;
purely electric driving is possible;
Starting the internal combustion engine by the electric machine is possible;
Starting the internal combustion engine during the purely electric driving with the electric machine is possible, even over different gears;
active synchronization of the switching operations is possible;
Boost mode, ie temporary connection of the electric machine is possible;
Recuperation, ie recovery of energy by means of the electric machine when braking the vehicle is possible;
Air compressor operation, in particular for battery cooling, at standstill of the vehicle is possible;
Obtained the AMT functionality (automated manual transmission) in case of failure of the electrical machine (fail safe);
good efficiency through consumption-optimized shift strategies using the good efficiency of a conventional gearbox (gear transmission) and thus fuel economy is possible;
depending on the choice of the switching elements and the friction clutch, no transmission hydraulics is required;
By using a particular electric parking brake or electrically controlled intervention in the operating system of the vehicle can be ensured that a start of the vehicle on a slope from the switching position 0-0 without a noticeable roll back of the vehicle is possible. The control system must be designed accordingly (Hillhold function).
Ein Umschalten von elektrischer Rückwärtsfahrt auf Vorwärtsfahrt und umgekehrt ist rückfrei möglich, da die elektrische Antriebsmaschine im kleineren Drehzahlbereich gegen die Eregungsrichtung drehen kann.One Switching from electric reverse on Forward drive and vice versa is possible because the electric drive machine in the smaller speed range can turn against the Eregungsrichtung.
Bei der Rekuperation im Bremsbetrieb ist es vorteilhaft, die Gangschaltzustände des Verbrennungsmotors zu reduzieren und den Gangschaltzustand der elektrischen Maschine beizubehalten, da sich dies für das Getriebeausgangsdrehmoment rückfrei abbildet. Sofern die Gangschaltzustände des Verbrennungsmotors reduziert werden sollen, wäre es vorteilhaft während des Schaltvorgangs das negative Motordrehmoment des Verbrennungsmotors mittels einer Motorbremse kurz zu reduzieren oder kurzfristig einen Bremseingriff des Fahrzeugs zu erzeugen, da andernfalls der Verbrennungsmotor den kurzfristigen Wegfall oder Bremswirkung der im Generatorbetrieb arbeitenden elektrischen Maschine während des Schaltvorgangs nicht ausgleichen könntenat the recuperation in braking mode, it is advantageous to the gear shift states to reduce the internal combustion engine and the gear shift state of maintain electric machine, since this is for the Transmission output torque reflected backless. Unless the Gear shift states of the internal combustion engine can be reduced should it be beneficial during the switching process the negative engine torque of the internal combustion engine by means of a Engine brake short to reduce or short-term braking intervention of the vehicle, otherwise the internal combustion engine the short-term omission or braking effect of generator operation working electrical machine during the switching process could not compensate
