Stand der TechnikState of the art
Aus der
Mit der elektrischen Aktuatorik ist das Doppelkupplungsgetriebe in der Lage, bei abgetrenntem Verbrennungsmotor automatisch zu kuppeln und zu schalten. Es ist somit vorbereitet für ein Start/Stopp-System und eine erweiterte Segelfunktion, bei der das Fahrzeug bei abgekoppeltem Verbrennungsmotor frei rollt. Die elektrische Aktuatorik ermöglicht darüber hinaus die einfache Hybridisierung des Getriebes, durch die zusätzliche E-Maschine.With the electric actuator, the dual-clutch transmission is able to automatically engage and disengage when the internal combustion engine is disconnected. It is thus prepared for a start / stop system and an extended sailing function in which the vehicle rolls freely with the combustion engine disconnected. The electrical actuator also allows easy hybridization of the transmission, through the additional electric motor.
Das Hybridgetriebe erlaubt alle Hybrid-Betriebsarten wie rein elektrisches Fahren, Unterstützung des Verbrennungsmotors und die Rückgewinnung von elektrischer Energie. Das Wiederstarten des Verbrennungsmotors per E-Maschine ist unabhängig vom Hybridisierungsgrad möglich.
Eine achsparallele Anordnung ermöglicht es, die Drehmomente von Verbrennungsmotor und E-Maschine über getrennte mechanische Pfade zu leiten. So kann beispielsweise die E-Maschine unabhängig vom Verbrennungsmotor die Gänge
Die Mild-Hybrid-Version nutzt eine E-Maschine mit einer Leistung von 15 kW. Mit diesem Hybridsystem ist rein elektrisches Fahren mit bis zu 20 km/h möglich und es können Kraftstoffeinsparungen erzielt werden.
Dabei ist erstrebenswert, möglichst viel Energie zurückzugewinnen und die elektrische Maschine im Rekuperationsbetrieb anzusteuern.
In einem geringen Geschwindigkeitsbereich bei einer Geschwindigkeit von unter 20 km/h im Rekuperationsbetrieb und bei stehenden Verbrennungsmotor tritt das Problem auf, den Verbrennungsmotor zu starten oder einen Gang im Teilgetriebe der elektrischen Maschine zu wechseln, ohne dass es zu unangenehmen Bremsmomenten für den Fahrer führt.The hybrid transmission allows all hybrid modes such as pure electric driving, support of the internal combustion engine and the recovery of electrical energy. Restarting the combustion engine by electric motor is possible regardless of the degree of hybridization.
An axis-parallel arrangement makes it possible to direct the torques of the combustion engine and electric motor via separate mechanical paths. For example, the e-machine can run independently of the
The mild hybrid version uses an electric motor with a power of 15 kW. With this hybrid system, electric driving of up to 20 km / h is possible and fuel savings can be achieved.
It is desirable to recover as much energy as possible and to control the electric machine in recuperation operation.
In a low speed range at a speed of less than 20 km / h in recuperation and stationary combustion engine, the problem arises to start the engine or to change gear in the partial transmission of the electric machine, without resulting in unpleasant braking torques for the driver.
Es ist daher Aufgabe Erfindung ein Verfahren zur Ansteuerung eines Hybrid Fahrzeuges zu schaffen, das auch im Rekuperationsbetrieb bei geringen Geschwindigkeiten eine reibungslose Zündung des Verbrennungsmotors oder einen Gangwechsel im Teilgetriebe der elektrischen Maschine erlaubt.It is therefore an object of the invention to provide a method for controlling a hybrid vehicle which, even in recuperation operation at low speeds, permits a smooth ignition of the internal combustion engine or a gear change in the partial transmission of the electric machine.
Die Aufgabe wird gelöst mit einem Verfahren zum Ansteuern eines Stufengetriebes für ein Kraftfahrzeug, das mindestens eine elektrische Maschine und einen Verbrennungsmotor zur Bereitstellung von Antriebsleistung aufweist, wobei das Stufengetriebe in ein erstes und ein zweites Teilgetriebe unterteilt ist und eine Mehrzahl von Gangstufen aufweist, die mittels jeweiliger Synchron-Schaltkupplungen ein- und auslegbar sind, wobei das erste Teilgetriebe mittels einer ersten Kupplung mit dem Verbrennungsmotor verbindbar ist, wobei das zweite Teilgetriebe mittels einer zweiten Kupplung mit dem Verbrennungsmotor verbindbar ist, wobei die elektrische Maschine (
Durch die erfindungsgemäße Lösung wird das Bremsverhalten optimiert.By the solution according to the invention the braking behavior is optimized.
Dabei wird das Rekuperationsmoment reduziert, während bei eingelegter Gangstufe im zweiten Teilgetriebe die Kupplung schließt und dadurch ein Bremsmoment aufbringt. Das Bremsmoment wird als Kupplungsmoment gegen den stillstehenden Verbrennungsmotor aufmoduliert.In this case, the recuperation torque is reduced, while the engaged gear ratio in the second partial transmission, the clutch closes and thereby applies a braking torque. The braking torque is modulated as a clutch torque against the stationary internal combustion engine.
Alternativ wird das Rekuperationsmoment reduziert, während Bremsmoment durch eine Fahrzeugbremse aufgebracht wird. Diese Lösung erfordert entweder eine zusätzliche Bremse oder kann durch den Einsatz der normalen Radbremsen durchgeführt werden. Alternatively, the recuperation torque is reduced while braking torque is applied by a vehicle brake. This solution either requires an extra brake or can be done by using the normal wheel brakes.
Es ist von Vorteil, dass das Bremsmoment im zweiten Teilgetriebe im Verlauf so aufgebracht wird, dass es das fehlende Bremsmoment im ersten Teilgetriebe kontinuierlich kompensiert. Durch diese Maßnahmen wird ein weicher Übergang der Bremsmomente erreicht.It is advantageous that the braking torque in the second partial transmission is applied in the course of time so that it continuously compensates for the missing braking torque in the first partial transmission. These measures achieve a smooth transition of the braking torques.
Weiterhin ist es von Vorteil, dass das Bremsmoment im Verlauf zunächst zunimmt und bei abnehmender Geschwindigkeit abnimmt. Damit wird eine Überkompensation vermieden.Furthermore, it is advantageous that the braking torque initially increases in the course and decreases with decreasing speed. This avoids overcompensation.
In einer alternativen Ausgestaltung wird das Bremsmoment bei einer Geschwindigkeit unter 5 km/h auf null gesetzt, was den parallel erfolgenden Wiederstart der Verbrennungsmaschine erleichtert.In an alternative embodiment, the braking torque is set to zero at a speed below 5 km / h, which facilitates the parallel restart of the internal combustion engine.
Es ist für einen Start der Verbrennungsmaschine nötig, die elektrische Maschine mit dem ersten Teilgetriebe in eine neutralen Gangstellung zu bringen, bevor die erste Kupplung im geschlossen wird.It is necessary for a start of the internal combustion engine to bring the electric machine with the first partial transmission in a neutral gear position, before the first clutch is in the closed.
Vorteilhafterweise wird die zweite Kupplung im mit einem zeitlichen Versatz zum Beginn der Reduzierung des Rekuperationsmoments geschlossen, um einen weichen Übergang zwischen den unterschiedlichen Bremsmomenten zu erzielen.Advantageously, the second clutch is closed with a time delay at the beginning of the reduction of the Rekuperationsmoments to achieve a smooth transition between the different braking torques.
Die Aufgabe wird weiterhin gelöst mit einer Steuereinrichtung zur Ansteuerung eines Antriebsstranges eines Kraftfahrzeuges, wobei die Steuereinrichtung dazu eingerichtet ist, das erfindungsgemäße Verfahren durchzuführen.The object is also achieved with a control device for controlling a drive train of a motor vehicle, wherein the control device is adapted to carry out the method according to the invention.
Vorteilhafterweise umfasst das Verfahren zum Ansteuern eines Antriebsstrangs mit einem Stufengetriebe eine Ausführungsform, in der das zusätzliches Bremsmoment durch eine Fahrzeugbremse und/oder durch eine weitere elektrische Maschine aufgebracht wird, wobei die weitere elektrische Maschine auf eine elektrische Vorderachse oder eine elektrische Hinterachse des Kraftfahrzeugs wirkt. Die Aufgabe wird weiterhin gelöst mit einem Antriebsstrang für ein Kraftfahrzeug mit einer elektrischen Maschine und einem Doppelkupplungsgetriebe, das eine Mehrzahl von Gangstufen aufweist, die mittels jeweiliger Synchron-Schaltkupplungen ein- und auslegbar sind, wobei die elektrische Maschine mit einem Eingang des Stufengetriebes verbunden oder mittels einer Koppeleinrichtung verbindbar ist, und mit einer Steuereinrichtung, die das erfindungsgemäßen Verfahren arbeitet.Advantageously, the method for controlling a drive train with a step transmission comprises an embodiment in which the additional braking torque is applied by a vehicle brake and / or by another electric machine, wherein the further electric machine acts on an electric front axle or an electric rear axle of the motor vehicle. The object is further achieved with a drive train for a motor vehicle having an electric machine and a dual-clutch transmission, which has a plurality of gear stages, which are switched on and off by means of respective synchronous clutches, wherein the electric machine connected to an input of the stepped transmission or by means a coupling device is connectable, and with a control device which operates the method according to the invention.

In diesem dritten Antriebsmodus rekuperiert die elektrische Maschine
Bewegt sich das Fahrzeug in einer Geschwindigkeitsbereich unterhalb von 20 km/h, bzw. zwischen 5 und 15 km/h, befindet es sich im Bereich des sogenannten „Slow Starts“. Um eine möglichst großes Rekuperationsmoment zur erhalten wird in diesem Segelbetrieb beispielsweise der vierte Gang des ersten Teilgetriebes eingelegt.If the vehicle moves in a speed range below 20 km / h, or between 5 and 15 km / h, it is in the range of the so-called "slow start". In order to obtain the largest possible recuperation moment, in this sailing mode, for example, the fourth gear of the first subtransmission is engaged.
In diesem Geschwindigkeitsbereich ist ein Wiederstart des Verbrennungsmotors mit der elektrischen Maschine nicht mehr mit dem eingelegtem vierten Gang möglich, da die Drehzahl des Leistungsübertragungspfad
Daher wird bisher die elektrische Maschine vom Abtrieb abgekoppelt, wobei im ersten Teilgetriebe die Gangstellung „neutral“ eingelegt ist. Anschließend wird die elektrische Maschine über die erste Kupplung
Allerdings empfindet der Fahrer den Wegfall des Rekuperationsmoments der elektrischen Maschine als unangenehm.However, the driver feels the elimination of the recuperation of the electric machine as unpleasant.
Unabhängig vom Neustart des Verbrennungsmotors kann auch ein Gangwechsel im ersten Teilgetriebe

Parallel dazu wird durch Schließen der zweiten Teilkupplung
Die zweite Teilkupplung wird dabei in einem Maße geschlossen, indem sie das Rekuperationsmoment der elektrischen Maschine durch das Bremsmoment des Verbrennungsmotors und eines eingelegten Ganges kompensiert. Dadurch bleibt das Verzögerungsmoment im Abtrieb in etwa gleich groß.The second part clutch is closed to an extent by compensating the recuperation of the electric machine by the braking torque of the engine and an engaged gear. As a result, the deceleration torque in the output remains approximately the same.

Der Verlauf der Fahrzeuggeschwindigkeit ist dabei wie rechten Bereich der Figur dargestellt parallel zum Rekuperationsmoment. Es ist im ersten Teilgetriebe

Im kompletten Übergangsbereich verbleibt der vierte oder zweite Gang in eingelegter Stellung. Das von der elektrischen Maschine
In der Regel ist im zweiten Teilgetriebe
Falls kein Gang oder ein falscher Gang voreingelegt wurde, muss der zur Überbrückung vorgesehene Gang, beispielsweise der dritte Gang eingelegt werden. Das Voreinlegen des dritten Ganges sollte jedoch frühzeitig, spätestens jedoch zum Zeitpunkt geschehen, wo die Getriebesteuerung den Wunsch äußert, in ersten Teilgetriebe

In einer alternativen Ausführungsform ist es auch möglich das Kupplungsmoment mit kleiner werdenden Geschwindigkeiten zu reduzieren.In an alternative embodiment, it is also possible to reduce the clutch torque with decreasing speeds.
Eine optimierte Lösung fährt dabei bei einer Geschwindigkeit von unter 5 km/h das Kupplungsmoment auf null zurück.An optimized solution drives the clutch torque back to zero at a speed of less than 5 km / h.

Im Segelbetrieb eines solchen Fahrzeugs können beide oder alle drei elektrischen Maschinen Energie durch Rekuperieren zurückgewinnen.In sailing operation of such a vehicle, both or all three electric machines can recover energy by recuperation.
