Nachfolgend wird in der Beschreibung der Erfindung ohne Einschränkung des Schutzumfangs beispielhaft von einem weitgehend identischen Aufbau des Antriebsstrangs ausgegangen, wobei die Überbrückungskupplung als Reibungskupplung vorausgesetzt wird, insbesondere als nasse Lamellenkupplung, alternativ aber auch als Trockenkupplung ausgeführt sein kann. Alternativ zu der bekannten Anordnung kann die Überbrückungskupplung auch zwischen dem Hohlrad und dem Sonnenrad, also zwischen der Kurbelwelle des Verbrennungsmotors und dem Rotor der Elektromaschine, angeordnet sein.following is in the description of the invention without limitation of Scope of protection by way of example of a largely identical structure the drive train is assumed, wherein the lock-up clutch as a friction clutch is assumed, in particular as a wet multi-plate clutch, alternatively but can also be designed as a dry clutch. alternative to the known arrangement, the lock-up clutch between the Ring gear and the sun gear, so between the crankshaft of the engine and the rotor of the electric machine, be arranged.
Im normalen Fahrbetrieb ist die Überbrückungskupplung vollständig geschlossen, so dass das Planetengetriebe blockiert ist und starr umläuft. In diesem Betriebszustand sind die Drehzahlen und die Drehrichtungen des Verbrennungsmotors, der Elektromaschine und der Eingangswelle des Schaltgetriebes identisch. Die Elektromaschine wird in diesem Zustand vorwiegend als Generator zur Versorgung des elektrischen Bordnetzes betrieben, kann jedoch in bestimmten Betriebssituationen, insbesondere in Beschleunigungsphasen des Kraftfahrzeugs, vorübergehend auch als Motor betrieben werden.in the normal driving is the lock-up clutch Completely closed, so that the planetary gear is blocked and rigid circulates. In In this operating state are the speeds and directions of rotation of the internal combustion engine, the electric machine and the input shaft of the gearbox identical. The electric machine is in this Condition mainly as a generator to supply the electrical But can in certain operating situations, especially in acceleration phases of the motor vehicle, temporarily also be operated as a motor.
Zum Gangwechsel innerhalb des Schaltgetriebes wird nahezu zeitgleich das Drehmoment des Verbrennungsmotors reduziert, die Elektromaschine kraftlos geschaltet und die Überbrückungskupplung vollständig geöffnet. Hierdurch wird die Eingangswelle des Schaltgetriebes von dem Verbrennungsmotor entkoppelt, so dass der eingelegte Lastgang lastfrei ausgelegt und der einzulegende Zielgang lastfrei synchronisiert und eingelegt werden kann. Die Synchronisierung des Zielgangs, also die Beschleunigung der Eingangswelle bei einer Rückschaltung und die Verzögerung der Eingangswelle bei einer Hochschaltung, erfolgt bei synchronisierten Schaltkupplungen durch Reibung, wobei die Anpresskraft der Reibelemente der Schaltkupplungen jeweils über die Stellkraft des zugeordneten Schaltstellers aufgebracht werden muss.For gear change within the gearbox, the torque of the engine is almost simultaneously reduced, switched off the electric machine and fully open the lock-up clutch. As a result, the input shaft of the gearbox is decoupled from the engine, so that the loaded load gear designed to be load-free and the target gear to be engaged synchronized and loaded load-free. The synchronization of the target gear, so the acceleration of the input shaft in a downshift and the delay of the input shaft at a high circuit, occurs in synchronized clutches by friction, wherein the contact pressure of the friction elements of the clutches must be applied in each case via the actuating force of the associated switch actuator.
Bei unsynchronisierten Schaltkupplungen kann die Synchronisierung des Zielgangs über einen speziellen Synchronisationsantrieb erfolgen, der mit der Eingangswelle des Schaltgetriebes in Verbindung steht. Dies erfordert jedoch nachteilig einen zusätzlichen Kosten- und Gewichtsaufwand sowie einen zusätzlichen Platzbedarf für den Synchronisationsantrieb.at unsynchronized clutches can synchronize the Targeting over a special synchronization drive made with the input shaft of the gearbox is in communication. However, this requires disadvantageous An additional Cost and weight and an additional space for the synchronization drive.
Alternativ dazu ist eine Synchronisierung des Zielgangs mit dem Verbrennungsmotor bei zumindest teilweise geschlossener Überbrückungskupplung möglich. Da der Verbrennungsmotor aufgrund seines relativ hohen Trägheitsmomentes und wegen seiner Steuerung über die Beeinflussung des Verbrennungsvorgangs vergleichsweise träge auf Steuerbefehle reagiert, nimmt eine derartige Synchronisierung einen relativ großen Zeitraum in Anspruch, wodurch der gesamte Schaltvorgang und die damit verbundene Zugkraftunterbrechung verlängert sind.alternative this is a synchronization of the target gear with the internal combustion engine possible with at least partially closed lock-up clutch. There the internal combustion engine due to its relatively high moment of inertia and because of its control over the influence of the combustion process comparatively slow to control commands reacts, takes such a synchronization a relatively large period claiming, whereby the entire switching process and the associated Traction interruption extended are.
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem bei einem Antriebsstrang der eingangs genannten Art bei einem Schaltvorgang zwischen einem Lastgang und einem Zielgang die Synchronisierung des Zielgangs beschleunigt durchgeführt werden kann. Ein solches Verfahren soll auch in Antriebssträngen nutzbar sein, die vergleichbare Komponenten, jedoch in anderer Antriebskopplungskombination enthalten.In front In this background, the present invention has the object underlying to provide a method with which in a powertrain of the type mentioned in a switching operation between a Load gear and a target gear speeds up the synchronization of the target gear carried out can be. Such a method should also be usable in drive trains be comparable components, but in other propulsion combination combination contain.
Die Erfindung ist durch die Merkmale des Hauptanspruchs angegeben, während vorteilhafte Ausgestaltungen den Unteransprüchen entnehmbar sind.The Invention is indicated by the features of the main claim, while advantageous embodiments the dependent claims are removable.
Demnach geht die Erfindung aus von einem Verfahren zur Steuerung eines Kraftfahrzeug-Antriebsstrangs, der einen Verbrennungsmotor, eine Elektromaschine und ein mit unsynchronisierten Schaltkupplungen versehenes Getriebe, vorzugsweise ein automatisiertes Schaltgetriebe, umfasst, die über ein Summierungsgetriebe mit zwei Eingangselementen und einem Ausgangselement sowie über eine als Reibungskupplung ausgebildete Überbrückungskupplung miteinander gekoppelt sind, wobei das erste Eingangselement mit der Kurbelwelle des Verbrennungsmotors, das zweite Eingangselement mit dem Rotor der Elektromaschine und das Ausgangselement mit der Eingangswelle des Getriebes drehfest verbunden ist, und bei dem die Überbrückungskupplung zwischen zwei Elementen des Summierungsgetriebes angeordnet ist, wobei bei einem Schaltvorgang zwischen einem Lastgang und einem Zielgang nach dem Ausfegen des Lastgangs der Zielgang synchronisiert und nachfolgend eingelegt wird.Therefore the invention is based on a method for controlling a motor vehicle drive train, an internal combustion engine, an electric machine and with unsynchronisierten clutches provided transmission, preferably an automated transmission, that covers over a summation gear with two input elements and one output element as well as over one formed as a friction clutch lock-up clutch with each other coupled, wherein the first input element with the crankshaft of the internal combustion engine, the second input element with the rotor the electric machine and the output element with the input shaft the transmission is rotatably connected, and wherein the lock-up clutch is arranged between two elements of the summation gear, wherein in a shift between a load gear and a target gear synchronized after sweeping the load gear of the target gear and will be inserted subsequently.
Unter den Begriff „Getriebe" fallen beispielsweise Handschaltgetriebe und automatisierte Schaltgetriebe.Under The term "gear", for example, fall Manual transmissions and automated manual transmissions.
Zudem ist erfindungsgemäß vorgesehen, dass der Zielgang bei geöffneter Überbrückungskupplung mittels der Elektromaschine synchronisiert wird, indem die Eingangswelle bei einer Rückschaltung durch ein in Drehrichtung der Kurbelwelle des Verbrennungsmotors und der Eingangswelle des Getriebes wirksames positives Drehmoment M_EM > 0 von der Elektromaschine auf die Synchrondrehzahl des Zielgangs beschleunigt wird, und bei einer Hochschaltung durch ein entgegen der Drehrichtung der Kurbelwelle des Verbrennungsmotors und der Eingangswelle des Getriebes wirksames negatives Drehmoment M_EM < 0 von der Elektromaschine auf die Synchrondrehzahl des Zielgangs verzögert wird.moreover is inventively provided that the target gear with opened lock-up clutch by means of the electric machine is synchronized by the input shaft at a downshift by a direction of rotation of the crankshaft of the internal combustion engine and the input shaft of the transmission effective positive torque M_EM> 0 from the electric machine is accelerated to the synchronous speed of the target gear, and at an upshift by an opposite to the direction of rotation of the crankshaft of the internal combustion engine and the transmission input shaft negative torque M_EM <0 is delayed by the electric machine to the synchronous speed of the target gear.
Da das Ansprechverhalten der Elektromaschine im Vergleich zu demjenigen des Verbrennungsmotors deutlich besser ist, ergibt sich über das Drehmoment M_EM der Elektromaschine ein schnelles Hochfahren oder Abbremsen der Elektromaschine selbst, und durch die Kopplung über das Summierungsgetriebe ebenfalls eine schnelle Beschleunigung oder Verzögerung der Eingangswelle des Getriebes, wodurch der Synchronisiervorgang beschleunigt und die dadurch bedingte Zugkraftunterbrechung verkürzt ist.There the response of the electric machine compared to that of the internal combustion engine is significantly better, results from the torque M_EM the electric machine a quick startup or braking the electric machine itself, and by the coupling over the Summation gear also a fast acceleration or delay the input shaft of the transmission, causing the synchronization process accelerated and the consequent interruption of traction is shortened.
Das Drehmoment M_EM der Elektromaschine wird dabei über das Summierungsgetriebe gegenüber dem Verbrennungsmotor abgestützt. Es ist daher für den Synchronisationsvorgang von Bedeutung, wie der Verbrennungsmotor während der Synchronisierung gesteuert wird, insbesondere wel che Drehzahl n_VM beziehungsweise welcher Drehzahlverlauf der Verbrennungsmotor während der Synchronisierung aufweist.The Torque M_EM of the electric machine is about the summation across from supported the internal combustion engine. It is therefore for the synchronization process of importance, such as the internal combustion engine while the synchronization is controlled, in particular wel che speed n_VM or which speed curve of the internal combustion engine while the synchronization has.
Der Verbrennungsmotor wird am einfachsten während der Synchronisierung der Eingangswelle auf einer weitgehend konstanten Drehzahl n_VM, insbesondere zu Beginn des Schaltvorgangs gehalten. Dies ist steuerungstechnisch einfach zu realisieren, hat aber den Nachteil, dass die von der Elektromaschine zu überwindende Drehzahldifferenz Δn_EM = n_EM_soll – n_EM_ist aufgrund der wirksamen Übersetzung dann deutlich größer ist als die Drehzahldifferenz Δn_GE = n_GE_soll – n_GE_ist, die zur Synchronisierung des Zielgangs von der Eingangswelle des Getriebes zu überbrücken ist. So ist bei der Verwendung eines Planetengetriebes mit der Standübersetzung i0 = –3 als Summierungsgetriebe in der bekannten Anordnung die von der Elektromaschine zu bewältigende Drehzahldifferenz bei konstant gehaltener Drehzahl n_VM des Verbrennungsmotors mit Δn_EM = Δn_GE(1 – i0) viermal so groß wie diejenige der Eingangswelle.The internal combustion engine is most easily kept during the synchronization of the input shaft at a substantially constant speed n_VM, in particular at the beginning of the switching operation. This is simple to implement in terms of control engineering, but has the disadvantage that the speed difference Δn_EM = n_EM_set_n_EM_ist to be overcome by the electric machine is then significantly greater than the speed difference Δn_GE = n_GE_set_n_GE_act due to the effective gear ratio, which is used to synchronize the target gear from the input shaft of the transmission is to bridge. Thus, when using a planetary gear with the state ratio i 0 = -3 as summation in the known arrangement that of the electroma engine speed to be handled at a constant speed n_VM of the internal combustion engine with Δn_EM = Δn_GE (1 - i 0 ) four times as large as that of the input shaft.
Es
ist daher zweckmäßig, die
Synchronisierung mittels der Elektromaschine durch den Verbrennungsmotor
zu unterstützen,
indem der Verbrennungsmotor während
der Synchronisierung der Eingangswelle bei einer Rückschaltung
durch Vorgabe einer erhöhten
Solldrehzahl n_VM_soll beschleunigt und bei einer Hochschaltung
durch Vorgabe einer abgesenkten Solldrehzahl n_VM_soll verzögert wird. Die
Synchronisierung des Zielgangs wird hierdurch zusätzlich beschleunigt
und die Dauer der Zugkraftunterbrechung weiter verkürzt. Die
Zieldrehzahl n_EM_soll der Elektromaschine ergibt sich in diesem Fall
aus der Zieldrehzahl n_GE_soll der Eingangswelle und der Istdrehzahl
n_VM_ist des Verbrennungsmotors zu:
Die Unterstützung der Synchronisierung des Zielgangs mit dem Verbrennungsmotor ist mit dem zusätzlichen Vorteil verbunden, dass sich die Drehzahl n_VM des Verbrennungsmotors zum Ende der Synchronisierung und dem nachfolgenden Einlegen des Zielgangs der Drehzahl n_GE der Eingangswelle schon weitgehend angenähert hat, so dass die üblicherweise nach einem Schaltvorgang erforderliche Angleichung der beiden Drehzahlen entfallen kann oder zumindest deutlich verkürzt ist.The support the synchronization of the target gear with the internal combustion engine is with the additional Advantage associated with the speed n_VM of the internal combustion engine to the end of the synchronization and the subsequent insertion of the Targeting the speed n_GE has already largely approximated the input shaft, so that usually After a switching process required approximation of the two speeds can be omitted or at least significantly shortened.
Wenn zum Zeitpunkt des Einlegens des Zielgangs schon Synchronlauf (n_VM = n_GE) zwischen dem Verbrennungsmotor und der Eingangswelle des Getriebes vorliegt, kann die Überbrückungskupplung vorteilhaft sofort geschlossen werden. Wenn dagegen zum Zeitpunkt des Einlegens des Zielgangs noch kein Synchronlauf besteht, wird die Drehzahl n_VM des Verbrennungsmotors nach dem Einlegen des Zielgangs zweckmäßig weiter an die Drehzahl n_GE der Eingangswelle angeglichen wird, und die Überbrückungskupplung mit Erreichen der Synchrondrehzahl (n_VM = n_GE) geschlossen und damit zum normalen Fahrbetrieb übergegangen.If at the time the target gear is engaged, synchronous operation (n_VM = n_GE) between the engine and the input shaft of the transmission is present, the lock-up clutch advantageous be closed immediately. If, however, at the time of insertion the target gear is not synchronized, the speed n_VM of the internal combustion engine after inserting the target gear appropriately further is matched to the speed n_GE of the input shaft, and the lock-up clutch closed when the synchronous speed (n_VM = n_GE) is reached and thus transferred to normal driving.
