Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Kraftfahrzeugs mit elektrischem Antrieb, wobei der elektrische Antrieb zumindest zwei Antriebseinheiten umfasst, die jeweils ein schaltbares Getriebe und einen E-Motor umfassen.The invention relates to a method for operating a motor vehicle with an electric drive, the electric drive comprising at least two drive units, each comprising a switchable transmission and an electric motor.
Die Kombination von elektrischen Maschinen mit Getrieben zu einer Motor-GetriebeEinheit ist aus dem allgemeinen Stand der Technik bekannt. Solche Motor-Getriebe-Einheiten können insbesondere in zumindest teilweise elektrischen Antriebsvorrichtung vorgesehen sein, wie sie beispielsweise für Hybridfahrzeuge oder rein elektrisch angetriebene Fahrzeuge eingesetzt werden.The combination of electrical machines with gears to form a motor-gear unit is known from the general prior art. Such motor-transmission units can be provided, in particular, in at least partially electric drive devices, such as those used for hybrid vehicles or purely electrically driven vehicles.
Aus der
Es wird vorgeschlagen das Getriebe derart zu schalten, dass das elektrisch erzeugte Gesamtmoment der Elektromaschinen vor und während der Schaltung unverändert bleibt und/oder dass die Zugkraftunterbrechung bei der Schaltung zu einem Giermoment um die Fahrzeughochachse führt, welches bedingt durch den Antriebslast- bzw. Bremsmomentabbau die Kurvenfahrt unterstützt.It is proposed to switch the transmission in such a way that the electrically generated total torque of the electric machines remains unchanged before and during the shift and / or that the interruption of tractive power during the shift leads to a yaw moment about the vertical axis of the vehicle, which due to the reduction in drive load or braking torque Cornering supported.
Die
Die Aufgabe der hier vorliegenden Erfindung besteht nun darin, ein verbessertes Verfahren für den Betrieb eines Kraftfahrzeugs mit mehreren elektrischen Antriebseinheiten vorzuschlagen.The object of the present invention is to propose an improved method for operating a motor vehicle with a plurality of electric drive units.
Die Aufgabe wird erfindungsgemäß durch ein Verfahren entsprechend Anspruch 1 gelöst. Weitere vorteilhafte Merkmale der erfindungsgemäßen Ausführung finden sich in den Unteransprüchen.The object is achieved by a method according to claim 1. Further advantageous features of the embodiment according to the invention can be found in the subclaims.
Erfindungsgemäß wird ein Verfahren zum Betreiben eines Kraftfahrzeugs, das einen elektrischen Antrieb mit zumindest zwei Antriebseinheiten umfasst, vorgeschlagen. Dabei umfasst jede Antriebseinheit einen E-Motor und ein Getriebe, wobei jede Antriebseinheit zumindest einem Fahrzeugrad zugeordnet ist und dieses antreibt. Gesteuert werden die Getriebe mittels einer Getriebesteuerung.According to the invention, a method for operating a motor vehicle, which comprises an electric drive with at least two drive units, is proposed. Each drive unit comprises an electric motor and a transmission, each drive unit being assigned to and driving at least one vehicle wheel. The gearboxes are controlled by means of a gearbox control.
Zur Verbesserung des Fahrkomfort wird vorgeschlagen, dass zumindest zwei Getriebe, die Schaltstufen und zumindest eine Neutralstellung aufweisen, Verwendung finden, wobei mittels der Getriebesteuerung die Getriebe derart geschaltet werden, dass sich bei der Fahrzeugbeschleunigung immer nur ein Getriebe in der Neutralstellung befindet. Durch diese Schaltung wird vermieden, dass es zu einer Zugkraftunterbrechung während des Schaltens kommt, was den Komfort erhöht.To improve driving comfort, it is proposed that at least two transmissions, which have shift stages and at least one neutral position, be used, the transmission being switched by means of the transmission control in such a way that only one transmission is in the neutral position during vehicle acceleration. This circuit prevents an interruption in tractive power during the shift, which increases comfort.
Der Schaltvorgang eines Getriebes einer Antriebseinheit erfolgt über die Getriebesteuerung, wobei der Schaltvorgang vorzugsweise folgende Schritte umfasst:
- - schalten des entsprechenden E-Motors in den Leerlauf
- - schalten des Getriebes in Neutralstellung
- - anpassen der Motordrehzahl des entsprechenden E-Motors auf Getriebeübersetzungsdrehzahl im gewünschten Gang
- - schalten des Getriebes in den gewünschten Gang.
- - Switch the corresponding electric motor to idle
- - Shift the transmission into neutral
- - Adjust the engine speed of the corresponding electric motor to gearbox speed in the desired gear
- - Shift the transmission into the desired gear.
In einer bevorzugten Ausführung sind die Getriebe als Zweiganggetriebe ausgeführt, wobei zwischen den Gängen eine Neutralstellung vorgesehen ist.In a preferred embodiment, the gears are designed as two-speed gears, with a neutral position being provided between the gears.
Es gibt nun unterschiedliche Möglichkeiten die Antriebseinheiten im Fahrzeug zu integrieren. In einer Ausführung ist es vorgesehen, dass an der Hinterachse des Fahrzeugs jedes Rad von einer Antriebseinheit angetrieben wird.There are now different ways to integrate the drive units in the vehicle. In one embodiment, it is provided that each wheel on the rear axle of the vehicle is driven by a drive unit.
Alternativ kann vorgesehen sein, dass an mindestens zwei Achsen des Fahrzeugs jeweils eine Antriebseinheit angeordnet ist, die jeweils die Räder der Achse antreibt. Zwischen der Getriebeeinheit und den Rädern der Achse, kann dann ein Differentialgetriebe angeordnet werden.Alternatively, it can be provided that at least two axles of the vehicle each have a drive unit that drives the wheels of the axle. A differential gear can then be arranged between the gear unit and the wheels of the axle.
Weiterhin ist es denkbar, dass an mindestens zwei der Achse des Fahrzeugs jeweils ein Rad von einer separaten Antriebseinheit angetrieben wird.Furthermore, it is conceivable that a wheel is driven by a separate drive unit on at least two of the axles of the vehicle.
Die Schaltung der Getriebe kann in Abhängigkeit von mindestens einem der folgenden Parameter abhängen:
- - Wartezeit
- - Motormoment
- - Achs-Eingangsdrehzahl
- - Motordrehzahl
- - Kurvenwinkel
- - Drehzahlunterschied der Räder
- - Motorenmoment
- - Beschleunigung

- - Fahrzeugmasse
- - GPS

- - curve angle
- - speed difference of the wheels
- - engine torque
- - acceleration
- - ABS condition
- - driving resistance
- - road gradient
- - vehicle mass
- - GPS
- - Driving route ahead
Anhand von Ausführungsbeispielen werden weitere vorteilhafte Ausprägungen der Erfindung erläutert unter Bezugnahme auf die Zeichnungen. Die genannten Merkmale können nicht nur in der dargestellten Kombination vorteilhaft umgesetzt werden, sondern auch einzeln untereinander kombiniert werden. Die Figuren zeigen im Einzelnen:

Die Getriebe
Nach der Beschleunigungsphase des Elektrofahrzeugs im ersten Gang erfolgt die Umschaltung in den zweiten Gang wie folgt:
- In einem ersten Schritt wird zunächst eines der Getriebe
5a in die Neutralstellung geschaltet, so dass das Fahrzeug1 nur noch vondem zweiten Antriebsstrang 4b angetrieben wird. Anschließend erfolgt eine Drehzahlanpassung des E-Motors6a , so dass die Motordrehzahl an die Getriebedrehzahl des zweiten Gangs angepasst ist, so dass der Antrieb des Elektrofahrzeugs1 mittels des zweiten Antriebsstrangs4b , im ersten Gang, und des ersten Antriebstrangs4a , im zweiten Gang, angetrieben wird.
The
After the acceleration phase of the electric vehicle in first gear, the switch to second gear takes place as follows:
- In a first step, one of the gears is first
5a switched to the neutral position so that the vehicle1 only from thesecond drive train 4b is driven. The speed of the electric motor is then adjusted6a , so that the engine speed is adapted to the transmission speed of the second gear, so that the drive of the electric vehicle1 by means of thesecond drive train 4b , in first gear, and thefirst drive train 4a , in second gear.
Anschließend kann das Getriebe
Durch dieses Vorgehen wird eine Unterbrechungsfreie Antriebsleistungsübertragung realisiert. Weiterhin Vorteilhaft erfolgt die Synchronisation beim Schalten durch die Drehzahlanpassung mit den E-Motoren

In allen Varianten wird die Schaltung der Getriebe zentral über die Getriebesteuerung gesteuert. Die Schaltung der Getriebe ist insbesondere für eine unterbrechungsfreie Fahrzeugbeschleunigung wichtig, um den Beschleunigungswechsel des Fahrzeugs
