An input side of an automatic transmission (4) is connected with the engine.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Betrieb eines Hybridfahrzeuges nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for operating a hybrid vehicle according to the preamble of patent claim 1.

Ein derartiges Verfahren ist beispielsweise im Zusammenhang mit einem (Voll-)Hybridfahrzeug aus der DE 10 2010 005 532 A1 bekannt. Hierbei wird die sogenannte „Response”-Problematik bei einem Zustart eines in einem ersten Betriebsmodus abgeschalteten Verbrennungsmotors behandelt. Unter dem Begriff „Response” ist die für den Fahrer spürbare Rückmeldung der Umsetzung seines Sollradmomenten- bzw. Beschleunigungswunsches zu verstehen. Diese Rückmeldung entsteht durch spürbare Zugkraft des Antriebsmotors über eine kraftschlüssige Verbindung zum Getriebe bzw. zu den Antriebsrädern, insbesondere bei lastbedingtem Zustart basierend auf einem Beschleunigungswunsch. Diese „Response” sollte also möglichst schnell spürbar sein.Such a method is for example in connection with a (full) hybrid vehicle from the DE 10 2010 005 532 A1 known. In this case, the so-called "response" problem is treated in the case of a start of an internal combustion engine switched off in a first operating mode. The term "response" is to be understood as meaning the feedback perceivable by the driver of the implementation of his desired wheel moment or acceleration desired. This feedback is caused by noticeable tensile force of the drive motor via a non-positive connection to the gearbox or to the drive wheels, especially in load-dependent condition based on an acceleration request. This "response" should therefore be felt as quickly as possible.

Es ist Aufgabe der Erfindung, ein Verfahren eingangs genannter Art im Hinblick auf die Verschleißreduzierung des Getriebes bei einem Zustart eines während der Fahrt zeitweise abgeschalteten Verbrennungsmotors zu verbessern.It is an object of the invention to improve a method of the type mentioned above with regard to the reduction in wear of the gearbox in the case of a booster engine that is temporarily switched off during the journey.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst. Abhängige Patentansprüche sind vorteilhafte Weiterbildungen der Erfindung.This object is achieved by the subject of claim 1. Dependent claims are advantageous developments of the invention.

Die Erfindung geht insbesondere von sogenannten straßengekoppelten Hybridfahrzeugen mit mindestens einem ersten Elektromotor, der als Antriebsmotor auf eine erste Achse des Hybridfahrzeugs wirkt, und mit einem Verbrennungsmotor, der als Antriebsmotor auf eine zweite Achse des Hybridfahrzeugs wirkt, aus.In particular, the invention is based on so-called road-coupled hybrid vehicles with at least one first electric motor, which acts as a drive motor on a first axis of the hybrid vehicle, and with an internal combustion engine, which acts as a drive motor on a second axis of the hybrid vehicle.

Derartige Hybridfahrzeuge sind in einem ersten Betriebsmodus, bei dem während der Fahrt mit rein elektromotorischem Antrieb durch den ersten Elektromotor der Verbrennungsmotor bei offenem Automatikgetriebe ausgeschaltet ist, und in einem zweiten Betriebsmodus, bei dem während der Fahrt der Verbrennungsmotor bei geschlossenem Automatikgetriebe angeschaltet ist, betreibbar.Such hybrid vehicles are in a first operating mode, in which is switched off while driving with purely electric motor drive by the first electric motor of the internal combustion engine with the automatic transmission open, and in a second operating mode in which the internal combustion engine is turned on while the automatic transmission is closed, operable.

Bei derartigen Hybridfahrzeugen ist es auch bekannt, zumindest zeitweise einen zweiten Elektromotor in Serie zum Verbrennungsmotor zu schalten. Die Momente des zweiten Elektromotors und des Verbrennungsmotors können in sich überlagernder Weise angesteuert werden.In hybrid vehicles of this kind, it is also known to switch a second electric motor in series with the internal combustion engine, at least temporarily. The moments of the second electric motor and the internal combustion engine can be controlled in superimposed manner.

Erfindungsgemäß wird in einer Zuschaltphase des Verbrennungsmotors während des Übergangs vom ersten Betriebsmodus in den zweiten Betriebsmodus mittels eines elektronischen Steuergerätes ein Soll-Moment des zweiten Elektromotors in der Weise eingestellt, dass das ansteigende Moment des startenden Verbrennungsmotors kompensiert wird. Bei einem derartigen Zustart des Verbrennungsmotors, bei dem auch ein offenes Getriebe (insbesondere Automatikgetriebe) geschlossen werden muss, also eine kraftschlüssige Verbindung zwischen Verbrennungsmotor und Getriebeausgang hergestellt werden muss („Ankoppelvorgang”), ist vor dem Ankoppelvorgang zunächst eine Zieldrehzahl am Getriebeeingang zu erreichen, die beim Ankoppeln etwa der Drehzahl des Verbrennungsmotors entsprechen muss (auch Synchrondrehzahl genannt). Die Zieldrehzahl ergibt sich aus Gang und Fahrzeuggeschwindigkeit. Erst ab Erreichen der Zieldrehzahl (Synchrondrehzahl) kann das Getriebe aus Verschleiß- und Komfortgründen mit dem Schließen der Kupplung(en) beginnen. Dabei können ähnlich wie bei einem Gangschaltvorgang die Komponenten des Automatikgetriebes durch verbleibende Drehzahldifferenzen verschleißen, da die Synchrondrehzahl nicht in idealer Weise eingestellt werden kann oder möglicherweise kein geeigneter Gang vorliegt.According to the invention, in a connection phase of the internal combustion engine during the transition from the first operating mode to the second operating mode by means of an electronic control unit, a desired torque of the second electric motor is adjusted in such a way that the rising torque of the starting internal combustion engine is compensated. In such a state of the internal combustion engine, in which an open gearbox (in particular automatic transmission) must be closed, so a non-positive connection between the engine and transmission output must be made ("Ankoppelvorgang"), before reaching the Ankoppelvorgang first reach a target speed at the transmission input, when coupling about the speed of the internal combustion engine must correspond (also called synchronous speed). The target speed results from gear and vehicle speed. Only when the target speed (synchronous speed) has been reached can the transmission begin to close the clutch (s) for reasons of wear and comfort. In this case, similar to a gearshift, the components of the automatic transmission by remaining speed differences wear out, since the synchronous speed can not be set in an ideal manner or may not be a suitable gear.

Durch die Erfindung wird daher das auf die Kupplung(en) des Automatikgetriebes während der Zuschaltphase wirkende Moment reduziert, um eine auslegungsrelevante Belastungsreduzierung zu erreichen. Somit können belastete Komponenten leichter ausgelegt und Gewicht sowie Kosten eingespart werden.By the invention, therefore, the torque acting on the clutch (s) of the automatic transmission during the Zuschaltphase is reduced in order to achieve a design-relevant load reduction. Thus, loaded components can be designed easier and weight and cost can be saved.

Die Erfindung ist besonders vorteilhaft bei systembedingten Zuschaltphasen, beispielsweise durch ein Unterschreiten einer definierten minimalen Batterieladungsschwelle, anzuwenden; denn dabei bleibt das Fahrerwunschmoment zunächst konstant. Durch die Erfindung kann insbesondere bei straßengekoppelten Hybridfahrzeugen die anzukoppelnde Achse lastfrei angekoppelt werden. Das Gesamtmoment, das sich aus dem Moment des ersten antreibenden Elektromotors an einer ersten Achse sowie aus dem Moment des zugeschalteten Verbrennungsmotors an der anzukoppelnden zweiten Achse ergeben kann, wird erfindungsgemäß erst nach dem Schließen des Automatikgetriebes bzw. dessen Kupplung(en) auf beide Achsen verteilt.The invention is particularly advantageous for system-related connection phases, for example, by falling below a defined minimum battery charge threshold to apply; because the driver's desired torque remains constant at first. By means of the invention, in particular in the case of hybrid hybrid vehicles, the axle to be coupled can be coupled without load. The total torque, which may result from the moment of the first driving electric motor on a first axis and from the moment of the connected internal combustion engine to be coupled to the second axis, according to the invention distributed after closing the automatic transmission or its clutch (s) on both axes ,

Details der Erfindung werden im hier folgenden Ausführungsbeispiel anhand der Zeichnung näher erläuter. Die einzige Figur zeigt eine schematische Darstellung des erfindungsgemäßen Verfahrens anhand eines straßengekoppelten Hybridfahrzeuges.Details of the invention are explained in more detail in the following embodiment with reference to the drawing. The single FIGURE shows a schematic representation of the method according to the invention with reference to a road-coupled hybrid vehicle.

In der einzigen Figur ist ein sogenanntes straßengekoppeltes Hybridfahrzeug mit einem ersten Elektromotor 1, der als Antriebsmotor beispielsweise auf die Vorderachse VA wirkt, und mit einem Verbrennungsmotor 3, der als Antriebsmotor auf die Hinterachse wirkt, dargestellt. Ein zweiter Elektromotor 2 ist in Serie zum Verbrennungsmotor 3 schaltbar. Ein Automatikgetriebe 4 ist eingangsseitig mit dem Verbrennungsmotor 3 verbindbar.In the single figure is a so-called road-coupled hybrid vehicle with a first electric motor 1 acting as a drive motor For example, acts on the front axle VA, and with an internal combustion engine 3 , which acts as a drive motor to the rear axle, shown. A second electric motor 2 is in series with the combustion engine 3 switchable. An automatic transmission 4 is input side with the internal combustion engine 3 connectable.

Analog ist die Erfindung auch für eine anders angeordnete Reihenfolge der Komponenten 2, 3 und 4 anwendbar; z. B. auch für eine Anordnung, bei der der Elektromotor 2 zwischen dem Verbrennungsmotor 3 und dem Automatikgetriebe 4 angeordnet ist.Analogously, the invention is also for a differently arranged sequence of the components 2 . 3 and 4 applicable; z. B. also for an arrangement in which the electric motor 2 between the internal combustion engine 3 and the automatic transmission 4 is arranged.

Das Hybridfahrzeug kann in einem ersten Betriebsmodus, bei dem während der Fahrt der Verbrennungsmotor 3 bei offenem Automatikgetriebe 4 ausgeschaltet ist, und in einem zweiten Betriebsmodus, bei dem während der Fahrt der Verbrennungsmotor 3 bei geschlossenem Automatikgetriebe 4 angeschaltet ist, betrieben werden. In einer Zuschaltphase des Verbrennungsmotors 4 wird während des Übergangs vom ersten Betriebsmodus in den zweiten Betriebsmodus mittels des elektronischen Steuergerätes 5 ein Soll-Moment 9 des zweiten Elektromotors 2 in der Weise eingestellt, dass das ansteigende Moment 8 des startenden Verbrennungsmotors 3 kompensiert wird. Die Kompensation des Moments 8 des Verbrennungsmotors 3 durch das Soll-Moment 9 des zweiten Elektromotors 2 wird vorzugsweise vom Beginn t1 der Zuschaltphase bis zur zumindest nahezu vollständigen Kraftschlussherstellung vorgenommen, damit die Hinterachse lastfrei angekoppelt wird. Somit wird erst nach Schließen der für die Kraftschlussherstellung notwendigen Kupplung(en) 6 zum Zeitpunkt t2 das gesamte Antriebsmoment des Verbrennungsmotors 3 und des ersten Elektromotors 1 auf beide Achsen verteilt. Danach wir das kompensierende Soll-Moment 9 des zweiten Elektromotors wieder – vorzugsweise rampenförmig – auf Null zurückgeführt.The hybrid vehicle may be in a first mode of operation in which the internal combustion engine is being driven 3 with open automatic transmission 4 is off, and in a second mode of operation, during which the internal combustion engine 3 with closed automatic transmission 4 is turned on, operated. In a connection phase of the internal combustion engine 4 is during the transition from the first operating mode in the second operating mode by means of the electronic control unit 5 a target moment 9 of the second electric motor 2 set in the way that the rising moment 8th of the starting combustion engine 3 is compensated. The compensation of the moment 8th of the internal combustion engine 3 through the target moment 9 of the second electric motor 2 is preferably made from the beginning of the t1 Zuschaltphase to at least almost complete adhesion, so that the rear axle is coupled without load. Thus, only after closing the coupling necessary for the adhesion 6 at time t2, the total drive torque of the internal combustion engine 3 and the first electric motor 1 distributed on both axes. After that we get the compensating target moment 9 of the second electric motor again - preferably ramped - returned to zero.

Die Erfindung ist besonders vorteilhaft, wenn der Verbrennungsmotor systembedingt, z. B. abhängig vom Ladezustand der Batterie, zugeschaltet wird, da dabei das Soll-Radmoment konstant bleibt.The invention is particularly advantageous when the internal combustion engine due to the system, z. B. depending on the state of charge of the battery, is switched on, since while the target wheel torque remains constant.

Soll das Soll-Radmoment beispielsweise durch einen erhöhten Fahrerwunsch (z. B. über Fahrpedalwinkel) ansteigen, kann dies erfindungsgemäß bis zur Kraftschlussherstellung verzögert werden. Auch könnte in diesem Fall bis zur Kraftschlussherstellung durch den ersten Elektromotor 1 eine Erhöhung des Soll-Radmoments zunächst noch übergangsweise durch den ersten Elektromotor 1 vorgenommen werden, sofern und soweit dieser noch eine Momentenreserve aufweist.If the desired wheel torque is to increase, for example, by an increased driver's request (eg via accelerator pedal angle), this can be delayed according to the invention until the adhesion is established. Also, in this case, could until the adhesion by the first electric motor 1 an increase of the target wheel torque initially still transitional by the first electric motor 1 if and insofar as it still has a reserve of torque.
