Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren zum Betrieb eines solchen Hybridantriebssystems vorzuschlagen, mit dem der Fahrzeugantrieb hinsichtlich des Fahrkomforts weiter 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 ride comfort on 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 Eingangswelle, die mit einer
Abtriebswelle koppelbar ist mittels einer ersten Gruppe von Gangschaltzahnradpaaren, wobei
die Eingangswelle mit der Hauptantriebsmaschine über eine
Reibungskupplung koppelbar ist,
ein zweites Gangschaltteilgetriebe
mit einer Eingangswelle, die mit der Abtriebswelle koppelbar ist mittels
einer zweiten Gruppe von Gangschaltzahnradpaaren, wobei die Eingangswelle
mit der Zusatzantriebsmaschine antriebsverbunden ist,
wobei
beim Wechseln der Gangschaltstufe der Hauptantriebsmaschine zumindest
für die Dauer, während der die Reibungskupplung
getrennt ist, im Zugbetrieb ein erhöhtes Drehmoment der
Zusatzantriebsmaschine und im Schubbetrieb ein reduziertes Drehmoment
der Zusatzantriebsmaschine eingeleitet wird.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 an input shaft couplable to an output shaft by means of a first group of gearshift gear pairs, the input shaft being coupleable to the main engine via a friction clutch,
a second gearshift subgear having an input shaft couplable to the output shaft by means of a second group of gearshift gear pairs, the input shaft being drive-connected to the auxiliary drive machine,
wherein when changing the gear shift stage of the main drive machine, at least for the duration during which the friction clutch is disconnected, an increased torque of the auxiliary drive machine and in traction mode a reduced torque of the auxiliary drive machine is initiated.
Dies gilt sowohl für hybride Fahrzustände mit Abtrieb durch beide Antriebsmaschinen als auch für Fahrzustände, in denen grundsätzlich nur die Hauptantriebsmaschine betrieben wird.This applies to hybrid driving conditions with downforce by both drive machines as well as for driving conditions, in which basically only the main drive machine operated becomes.
Hierbei ist vorgesehen, daß im Betrieb mit beiden Antriebsmaschinen ebenso wie mit Hauptantriebsmaschine alleine ohne Unterbrechung der Zugkraft weitgehend ruckfrei geschaltet wird, so daß der Fahrkomfort verbessert ist.in this connection is provided that in operation with both prime movers as well as with main propulsion engine alone without interruption the traction is switched largely smoothly, so that the ride comfort is improved.
In bevorzugter Ausführung ist vorgesehen, daß im Zugbetrieb vor dem Trennen der Reibungskupplung das Drehmoment der Hauptantriebsmaschine reduziert wird und das Drehmoment der Zusatzantriebsmaschine erhöht wird. Hierbei wird vorzugsweise nach dem Schließen der Reibungskupplung das Drehmoment der Hauptantriebsmaschine wieder erhöht und das Drehmoment der Zusatzantriebsmaschine wieder reduziert. Hierbei sollte das Drehmoment der Zusatzantriebsmaschine in dem Maße erhöht bzw. reduziert werden, wie das Drehmoment der Hauptantriebsmaschine reduziert bzw. erhöht wird, um ein ruckfreies Schalten zu ermöglichen.In preferred embodiment is provided that in Zugbetrieb before separating the friction clutch, the torque of the Main drive machine is reduced and the torque of the auxiliary drive machine is increased. This is preferably after closing the friction clutch the torque of the main engine again increases and the torque of the auxiliary drive machine again reduced. This should be the torque of the auxiliary drive machine be increased or reduced to the extent that reduces or increases the torque of the main drive machine is to allow a smooth switching.
Im Schubbetrieb findet eine umgekehrte Drehmomentanpassung statt. Demnach wird vor dem Trennen der Reibungskupplung das Drehmoment der Hauptantriebsmaschine erhöht und das Drehmoment der Zusatzantriebsmaschine reduziert. Wohingegen nach dem Schließen der Reibungskupplung das Drehmoment der Hauptantriebsmaschine reduziert und das Drehmoment der Zusatzantriebsmaschine erhöht wird.in the Push mode, a reverse torque adjustment takes place. Therefore Before turning off the friction clutch, the torque of the main drive machine increases and reduces the torque of the auxiliary drive machine. whereas after closing the friction clutch, the torque reduces the main drive machine and the torque of the auxiliary drive machine is increased.
Durch die Änderung der Drehmomente der Antriebsmaschinen vor dem Trennen der Reibungskupplung bzw. nach dem Schließen derselben, wird z. B. im Zugbetrieb der Antrieb ausschließlich von der Zusatzantriebsmaschine übernommen, während im Drehmomentpfad der Hauptantriebsmaschine ein Gangwechsel stattfindet.By the change of the torques of the prime movers the separation of the friction clutch or after closing the same, z. B. in train operation of the drive exclusively taken over by the auxiliary drive machine while A gear change takes place in the torque path of the main drive machine.
Grundsätzlich kann es erforderlich sein, die Änderung des Drehmoments der Zusatzantriebsmaschine zu beginnen, bevor das Drehmoment der Hauptantriebsmaschine geändert wird, insbesondere wenn es sich bei der Zusatzantriebsmaschine um eine elektrische Maschine handelt, da diese eine gewisse Anfahrverzögerung aufweisen können.in principle It may be necessary to change the torque the auxiliary drive machine to start before the torque of the main drive machine is changed, especially if it is the auxiliary drive machine is an electric machine, as this is a certain startup delay can have.
In bevorzugter Ausführung ist vorgesehen, daß das Drehmoment der Zusatzantriebsmaschine zunächst zunehmend erhöht und abschließend zunehmend reduziert wird. Hierbei kann zeitweise das Drehmoment der Zusatzantriebsmaschine konstant gehalten werden. Eine größtmögliche Verbesserung ist dadurch zu erzielen, daß das Drehmoment der Zusatzantriebsmaschine so variiert wird, daß am Getriebeausgang ein vollkommen stetiger Drehmomentverlauf erzeugt wird.In preferred embodiment is provided that the Torque of the auxiliary drive machine initially increasing increased and finally increasingly reduced. This can temporarily the torque of the auxiliary drive machine kept constant. A greatest possible Improvement is achieved in that the torque the auxiliary drive machine is varied so that the transmission output a completely steady torque curve is generated.
In Ausgestaltung des Verfahrens kann vorgesehen sein, daß beim Wechseln der Gangschaltstufe der Hauptantriebsmaschine für die Dauer des Trennvorgangs der Reibungskupplung das Drehmoment der Zusatzantriebsmaschine in Zugbetrieb zeitweise erhöht und anschließend reduziert und im Schubbetrieb zeitweise reduziert und anschließend erhöht wird.In Embodiment of the method can be provided that the Changing the gear shift stage of the main drive machine for the duration of the separation process of the friction clutch the torque the auxiliary drive machine in train operation temporarily increased and then reduced and temporarily in overrun mode reduced and then increased.
Mit dem Begriff der Dauer des Trennvorgang ist hierbei die Zeitspanne gemeint, innerhalb derer die Reibungskupplung nicht vollständig geschlossen ist, das heißt die Zeitspanne beginnend mit dem Trennen der Reibungskupplung bis zum vollständigen wieder Schließen der Reibungskupplung.With the term of the duration of the separation process is the time span meant within which the friction clutch is not complete is closed, that is, the period starting with separating the friction clutch until complete again closing the friction clutch.
Hierbei kann während des Trennens der Reibungskupplung in dem Maße, in dem durch das Trennen das von der Hauptantriebsmaschine reduzierte Drehmoment eingeleitet wird, das Drehmoment der Zusatzantriebsmaschine erhöht werden. Dies gilt für den Zugbetrieb. Im Schubbetrieb wird das Drehmoment der Zusatzantriebsmaschine reduziert. Während des Schließens der Reibungskupplung wird hingegen das Drehmoment der Zusatzantriebsmaschine im Zugbetrieb wieder reduziert und im Schubbetrieb wieder erhöht.in this connection can during the separation of the friction clutch to the extent in that by cutting the reduced torque from the main engine is initiated, the torque of the auxiliary drive machine increases become. This applies to train operation. In overrun mode is reduces the torque of the auxiliary drive machine. While the closing of the friction clutch, however, becomes the torque the auxiliary drive machine in train operation again reduced and in overrun mode raised again.
Somit übernimmt, in alternativer Ausgestaltung zur vorher beschriebenen Lösung, die Zusatzantriebsmaschine nicht vor dem Trennen der Reibungskupplung sondern während des Trennens der Reibungskupplung den Antrieb.Thus assumes, in an alternative embodiment to the previously described solution, the auxiliary drive machine not before disconnecting the friction clutch but during the separation of the friction clutch the drive.
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 order of opening and closing the friction clutch of the engine and a matched thereto Sequence of operation of the switching units of the various Gears is a traction-free shifting between the gears possible. Crucial for this type of operation is that in the transmission arrangement according to the invention the element to be switched (clutch, switching unit) always can be disconnected while at least one drive, either the electric machine or the internal combustion engine, with the output shaft is in torque transmitting connection. When switching can speed through the elements to be switched through appropriate control of the electric machine and the internal combustion engine adjusted, d. H. be synchronized. The friction clutch of Internal combustion engine allows a grinding connection of the internal combustion engine. The electric machine can also over a friction clutch to be coupled, their function but in the context the claimed method is not claimed.
Um das von der Zusatzantriebsmaschine auszugleichende Drehmoment genau ermitteln zu können, kann ein Drehmomentsensor zur Ermittlung des von der Hauptantriebsmaschine in das erstes Gangschaltteilgetriebe eingeleitete Drehmoment vorgesehen ist.Around the exact torque to be compensated by the auxiliary drive machine To be able to determine a torque sensor for determining the from the main drive machine to the first speed-change gearbox introduced torque is provided.
Aufgrund der gewählten Anordnung des Verbrennungsmotors und der elektrischen Maschine erfolgt bei Betrieb beider Antriebsmaschinen eine Drehmomentaddition. Wie nachfolgend dargestellt, ist ein Anfahren mit der elektrischen Maschine sowie ein Generatorbetrieb der elektrischen Maschine im Rekuperations-Modus möglich.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. As shown below, is a start with the electric machine as well as a generator operation of the electric Machine possible in recuperation mode.

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;The following essential features and advantages of the method according to the invention are next named:
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;
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).By Use of a particular electric parking brake or electrically controlled intervention in the operating system of the vehicle can be ensured that a startup of the vehicle on the slope from the switch position 0-0 without a noticeable roll back of the vehicle is possible. The control system is appropriate interpreted (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
