Entlang eines Antriebsstranges eines Fahrzeuges von einem oder mehreren Antriebsaggregaten bis hin zu den angetriebenen Rädern gibt es eine Vielzahl von Leistungsübertragungen, beispielsweise durch kämmende Zahnräder. Diese Leistungsübertragungen sind mit Spiel behaftet. Kommt es nun zu einer starken Drehmomentänderung im Antriebsstrang, insbesondere einer Drehmomentumkehr, so wird zunächst das Spiel im Antriebsstrang durchlaufen. Nachdem das Spiel durchlaufen wurde, wird der Drehimpuls schlagartig auf den Antriebsstrang übertragen. Dies ist als Lastwechselschlag bekannt.Along a drive train of a vehicle of one or more Drive units up to the driven wheels are it's a lot of power transfers, for example, by combing Gears. These power transfers are tainted with play. Is it now a strong torque change in the drive train, in particular a torque reversal, so is first go through the game in the powertrain. After going through the game was, the angular momentum is transmitted abruptly to the drive train. This is known as Lastwechselschlag.
Durch den Lastwechselschlag wird das subjektive Komfortempfinden des Fahrers negativ beeinflusst und es wird eine unerwünschte Schwingung in das Fahrzeug, insbesondere den Antriebsstrang eingeleitet.By the load change impact is the subjective sense of comfort of the driver negatively affected and there is an undesirable vibration in the vehicle, in particular the powertrain introduced.
Im Anschluss an den Spieldurchlauf wird beispielsweise durch ein Beschleunigen ein schneller Momentenaufbau erzeugt. Aufgrund der kinetischen Energie kommt es zu einem Überschwingen des Antriebsstranges. Diese Schwingungen sind als Ruckelschwingungen bekannt.in the Connection to the game run, for example, by accelerating generates a fast torque build-up. Due to the kinetic energy it comes to an overshoot of the drive train. These vibrations are called jerky vibrations known.
Bei Fahrzeugen mit konventionellem verbrennungsmotorischen Antrieb ist es bekannt, dass bei einem Beschleunigungsvorgang oder dem Übergang vom Schubbetrieb in den Zugbetrieb durch eine entsprechende Steuerung des Verbrennungsmotormoments, beispielsweise durch den Zündwinkel, ein Lastschlag bzw. eine Ruckelschwingung vermieden wird.at Vehicles with conventional internal combustion engine drive is It is known that during an acceleration process or transition from push operation to train operation by a corresponding control of the engine torque, for example by the ignition angle, a load shock or a jerky vibration is avoided.
Bei Fahrzeugen mit einem Verbrennungsmotor und einer Elektromaschine als Antriebe wird die Elektromaschine vorteilhaft ebenso generatorisch betrieben um Bremsenergie zurück zu gewinnen (Rekuperation).at Vehicles with an internal combustion engine and an electric machine as drives the electric machine is advantageously operated as well as generator back to braking energy to win (recuperation).
Mit Hilfe der Elektromaschine kann durch Einleiten eines positiven oder negativen Moments in den Antriebsstrang ein Lastschlag bzw. eine Ruckelfunktion unterdrückt werden.With Help the electric machine by initiating a positive or negative moments in the drive train a load blow or a Jerk function suppressed become.

Aufgabe der Erfindung ist es, den Komfort eines Fahrzeuges mit Hybridantrieb bei Maximierung des Rekuperationspotentials in allen Betriebsarten zu verbessern.task The invention is the comfort of a vehicle with hybrid drive while maximizing the recuperation potential in all modes improve.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass es vorgesehen ist, einen Lastwechselschlag bzw. eine Ruckelschwingung mit einer Frequenz kleiner als 20 Hertz durch eine Vorsteuerung der mindestens einen Elektromaschine zu vermeiden.These Task is inventively characterized solved, that it is provided, a load change shock or a jerky vibration with a frequency less than 20 Hertz by a pilot control to avoid the at least one electric machine.
Durch die erfindungsgemäßen Maßnahmen kann vorteilhaft der Komfort des Fahrzeuges durch die Vermeidung einer vom Fahrer negativ wahrgenommenen Längsbewegung des Fahrzeuges bzw. eines durch den Antriebsstrang verursachten Geräusches erhöht werden. Ebenso führt eine Vermeidung eines Lastwechselschlags bzw. einer Ruckelschwingung zu einem schnelleren Momentenwechsel und einer damit erhöhten Agilität des Fahrzeuges sowie zu einer Erhöhung des Rekuperationspotentials.By the measures according to the invention can advantageous the comfort of the vehicle by avoiding a negatively perceived by the driver longitudinal movement of the vehicle or caused by the drive train noise can be increased. Likewise leads an avoidance of a load change shock or a jerky vibration to a faster torque change and thus increased agility of the vehicle as well as to an increase the recuperation potential.
Findet das erfindungsgemäße Verfahren bei einem Wechsel vom Schubbetrieb in den Zugbetrieb statt, so kann der Verbrennungsmotor auf einem stetigeren Momentenverlauf geführt werden, was in einer Verbrauchseinsparung resultiert.finds the inventive method in a change from overrun to train operation instead, so can the combustion engine is guided on a more steady torque curve, which results in a consumption saving.
Insbesondere bei einem Wechsel vom Zugbetrieb in den Schubbetrieb ist es mit Hilfe einer Elektromaschine möglich, einen Lastschlag bzw. eine Ruckelschwingung zu vermeiden. Bei Fahrzeugen mit einem konventionellen verbrennungsmotorischen Antrieb ist dies nicht möglich, da der Verbrennungsmotor nicht den erforderlichen Momentenverlauf erzeugen kann.In particular, when changing from the train operation to the overrun operation, it is possible with the aid of an electric machine to avoid a load impact or a jerky vibration. For vehicles with a conventional internal combustion engine drive this is not possible because the engine can not produce the required torque curve.

Das Verbrennungsmotormoment MVM und das Elektromaschinenmoment MEM und somit auch das resultierende Summenmoment MGes werden erfindungsgemäß so gesteuert, dass ein Lastwechselschlag bzw. eine Ruckelschwingung vermieden werden.The engine torque M VM and the electric machine torque M EM and thus also the resulting sum torque M Ges are controlled according to the invention so that a load change impact or a jerk vibration can be avoided.
Während des
Zugbetriebes gemäß
Durch die Reduktion der Leistungsanforderung bis auf Null geht das Verbrennungsmotormoment MVM zeitverzögert in das negative Moment des Schubbetriebes des Verbrennungsmotors VM über.Due to the reduction of the power requirement down to zero, the engine torque M VM changes over time to the negative moment of the overrun operation of the internal combustion engine VM.
Um einen Lastschlag beim Übergang von einem positiven in ein negatives Summenmoment MGes (Flankenwechsel bei einem Zahnrad) zu vermeiden, wird das Elektromaschinenmoment MEM erfindungsgemäß in einer Weise gesteuert, dass der Gradient des Summenmoments MGes beim Momenten-Nulldurchgang möglichst klein ist und somit ein sanftes Anlegen der Zahnradflanke erfolgt.In order to avoid a load impact during the transition from a positive to a negative total moment M Ges (edge change in a gear wheel), the electric machine torque M EM is controlled according to the invention in such a way that the gradient of the total moment M Ges at the moment zero crossing is as small as possible and thus a gentle application of the gear edge takes place.
Für die erfindungsgemäße Steuerung des Elektromaschinenmoments MEM ist die Trägheit bzw. Dynamik des Antriebsstranges sowie des Verbrennungsmotors VM und der Elektromaschine P1, P2 zu berücksichtigen.For the inventive control of the electric machine torque M EM , the inertia or dynamics of the drive train and the internal combustion engine VM and the electric machine P1, P2 must be considered.

Das
Schubmoment des Verbrennungsmotors VM bleibt gemäß
Reicht die Vorsteuerung der mindestens einen Elektromaschine P1, P2 zur vollständigen Unterdrückung der Ruckelschwingung nicht aus, so kann die resultierende Schwingung durch eine Folgeregelung der mindestens einen Elektromaschine P1, P2 unterdrückt werden.Enough the feedforward control of the at least one electric machine P1, P2 for complete suppression the jerky vibration is not enough, so the resulting vibration by a subsequent control of the at least one electric machine P1, P2 suppressed become.
Erfindungsgemäß ist es ebenfalls möglich, dass der Wechsel vom Zugbetrieb direkt in einen Schubbetrieb mit Rekuperation erfolgt. Hierbei wird also mindestens eine der Elektromaschinen P1, P2 generatorisch betrieben.It is according to the invention also possible that the change from train operation directly to a coasting operation with recuperation he follows. In this case, therefore, at least one of the electric machines P1, P2 operated as a generator.
Es ist zu berücksichtigen, dass im Rekuperationsbetrieb die generatorisch betriebene Elektromaschine ein negatives Moment auf den Antriebsstrang ausübt, das beispielsweise bei einer veränderten Verzögerung oder bei einem Wechsel vom Zugbetrieb in den Schubbetrieb zu einer Torsion des Antriebsstranges und damit zu einer Ruckelschwingung führen kann.It is taken into account, that in recuperation the generator-operated electric machine a negative moment on the driveline exerts, for example, at a changed delay or in case of a change from the train operation to the overrun operation to a torsion of the drive train and thus can lead to a jerky vibration.
Die Steuerung der mindestens einen Elektromaschine P1, P2 im Schubbetrieb mit Rekuperation erfolgt ebenfalls in einer Weise, dass Ruckelschwingungen im Antriebsstrang vermieden werden.The Control of the at least one electric machine P1, P2 in coasting mode With recuperation also takes place in a way that jerking vibrations be avoided in the drive train.

P2 zusätzlich zu dem Verbrennungsmotor VM ein Moment in den Antriebsstrang einspeisbar ist oder aber ein im Antriebsstrang vorhandenes Moment (zumindest teilweise) zur Rekuperation elektrischer Energie genutzt werden kann.The Electric machines P1, P2 preferably have a housing-fixed Stator, which interacts with a rotor to produce a drive torque and / or recuperation of electrical energy interacts. The rotor is connected to the motor shaft M or the transmission input shaft E drivingly connected, so that by means of Electric machine P1 or P2 in addition to the internal combustion engine VM a moment in the drive train can be fed or is a moment present in the drive train (at least partially) can be used for recuperation of electrical energy.
