Abstract
Description
Die Erfindung betrifft ein Automatikgetriebe, insbesondere für ein Kraftfahrzeug mit einem Verbrennungsmotor mit einer Kurbelwelle, die mittels einer Kupplung in einem Antriebsstrang des Fahrzeugs mit dem Getriebe verbindbar ist, mit einem Getriebesteuergerät und mit einer, zur Druckölversorgung zur Schmierung und zur Betätigung der Steuerungselemente des Getriebes, unabhängig von einem Betrieb des Verbrennungsmotors regelbaren, elektrischen Ölpumpenantriebsmaschine einer Ölpumpe. The invention relates to an automatic transmission, in particular for a motor vehicle an internal combustion engine with a crankshaft, which by means of a clutch in a Drive train of the vehicle can be connected to the transmission with a Gearbox control unit and with one, for pressure oil supply for lubrication and Actuation of the control elements of the transmission, regardless of an operation of the Internal combustion engine adjustable, electric oil pump drive machine one Oil pump.
Konventionelle Automatikgetriebe von Kraftfahrzeugen benötigen zur Steuerung der Kupplungen, Bremsen und sonstigen Steuerungselementen eine Ölversorgung. Das Drucköl zur Steuerung wird durch eine Pumpe bereitgestellt, die direkt oder über eine Übersetzungsstufe vom Verbrennungsmotor angetrieben wird. Dabei greift man oft auf Zahnradpumpen oder Kolbenpumpen zurück. Die Fördercharakteristik dieser Pumpen ist so, dass sie einen Volumenstrom fördern, der nahezu proportional der Drehzahl der Pumpe und in weiten Betriebsbereichen fast unabhängig vom zu fördernden Druck ist. Das geförderte Öl wird von der Pumpe auf einen Hauptdruckschieber geleitet, der den gewünschten Hauptdruck für die Getriebesteuerung einstellt. Der benötigte Ölstrom setzt sich zusammen aus dem Leckageölstrom der Getriebesteuerung (Schieberkasten), dem zur Steuerung benötigten Volumenstrom und dem eventuell zur Kühlung von Kupplungen und Bremsen benötigten Kühlölstrom. Insbesondere bei der Verwendung von Lamellenkupplungen als Anfahrelemente ist der benötigte Kühlölstrom bereits bei geringen Motordrehzahlen ganz erheblich. Um für diese Anfahrkupplungen den erforderlichen Kühlölstrom bereit stellen zu können, muss die Pumpe ausreichend groß dimensioniert werden. Derartige, ständig von dem Verbrennungsmotor angetriebene Pumpen, stellen eine ständige Leistungssenke dar und vermindern dadurch den Gesamtwirkungsgrad des Getriebes. Conventional automatic transmissions of motor vehicles need to control the Clutches, brakes and other control elements provide an oil supply. The Pressure oil for control is provided by a pump, either directly or via a Gear ratio is driven by the internal combustion engine. You often take up this Gear pumps or piston pumps back. The delivery characteristics of these pumps is so that they promote a volume flow that is almost proportional to the speed of the Pump and in wide operating areas is almost independent of the pressure to be pumped. The pumped oil is directed to a main pressure valve, which is the desired main pressure for the transmission control. The required oil flow sets together from the leakage oil flow of the transmission control (valve body), the volume flow required for control and possibly for cooling couplings and brakes require cooling oil flow. Especially when using The required cooling oil flow is already at when multi-plate clutches are used as starting elements low engine speeds quite considerably. To the for these starting clutches To be able to provide the required cooling oil flow, the pump must be large enough be dimensioned. Such, constantly driven by the internal combustion engine Pumps represent a constant drop in performance and thereby reduce the Overall gearbox efficiency.
Das folgende Beispiel macht diese Zusammenhänge deutlich:
Es wird angenommen, dass für die Kühlung der Anfahrkupplung bei einer Motordrehzahl
von 2000 U/min 25 l/min Kühlöl eingesetzt werden müssen. Der Ölbedarf des
Schieberkastens, bestehend aus Leckage und Steueröl, beträgt 5 l/min. Die Kupplung ist
sind so ausgelegt, dass sie das maximale Motormoment bei einem Steuerdruck von 10 bar
übertragen kann. Für eine Volllastanfahrt ist dann eine hydraulische Leistung von
p.Q = 10 bar.30 l/min = 500 W erforderlich. Wird das gleiche Getriebe nun bei einer
Motordrehzahl von 6000 U/min betrieben, beträgt die bereitgestellte und damit die für
den Antriebstrang als Verlustleistung anzusetzende hydraulische Leistung bereits 1,5 kW
(Bei der tatsächlichen Verlustleistung ist zusätzlich noch der mechanische Wirkungsgrad
der Pumpe zu berücksichtigen). Die erforderliche Leistung ergibt sich dagegen aus dem
Öl- und Druckbedarf des Schieberkastens. Dieser Bedarf kann bei der gleichen Drehzahl
jedoch auch bei 5 l/min liegen. Die geforderte hydraulische Leistung beträgt dann also
lediglich 42 W. Der Wirkungsgrad der Ölpumpe in Verbindung mit dem
Hauptdruckschieber liegt dann lediglich bei 2,8%. Selbst wenn bei dieser hohen
Drehzahl der volle Kühlölstrom von 25 l/min bei einem Druck von 10 bar benötigt würde
(z. B. bei einer Schaltung), steigt der Wirkungsgrad der Druckversorgung gerade auf
33%.
The following example illustrates these relationships:
It is assumed that 25 l / min of cooling oil must be used to cool the starting clutch at an engine speed of 2000 rpm. The oil consumption of the valve body, consisting of leakage and control oil, is 5 l / min. The clutch is designed so that it can transmit the maximum engine torque at a control pressure of 10 bar. A hydraulic power of pQ = 10 bar. 30 l / min = 500 W is then required for a full load start. If the same gearbox is now operated at an engine speed of 6000 rpm, the hydraulic power provided and therefore the hydraulic power to be used as power loss for the drive train is already 1.5 kW (the actual power loss also takes the mechanical efficiency of the pump into account) , The required power, however, results from the oil and pressure requirements of the valve body. However, at the same speed, this requirement can also be 5 l / min. The required hydraulic output is then only 42 W. The efficiency of the oil pump in connection with the main pressure slide is then only 2.8%. Even if the full cooling oil flow of 25 l / min at a pressure of 10 bar would be required at this high speed (e.g. with a circuit), the efficiency of the pressure supply increases to 33%.
Eine Verbesserung des Wirkungsgrades ließe sich mit einer regelbaren Pumpe mit einstellbarer Drehzahl und/oder Förderrate erzielen. Eine mechanische Regelung der Förderrate erweist sich meist wegen großer Pulsationen der verstellbaren Pumpen (z. B. Radialkolbenpumpe) als sehr problematisch. Einfacher hingegen ist es, eine elektrische Maschine zu regeln. Für eine elektrisch geregelte Pumpe kann auf Erfahrungen aus dem Bereich elektro-hydraulischer Lenkhilfesysteme zurückgegriffen werden. Problematisch bei einer elektrisch betriebenen Pumpe ist allerdings ihr relativ hoher Energieverbrauch, der eine entsprechend hohe Batterie- und Generatorkapazität erfordert. Dies Problem wird noch dadurch verstärkt, dass größer dimensionierte Elektromotoren prinzipiell vorteilhafter sind, da sie im Allgemeinen eine höhere Lebensdauer besitzen. An improved pump could be used to improve efficiency achieve adjustable speed and / or delivery rate. A mechanical regulation of the Delivery rate mostly proves to be due to large pulsations of the adjustable pumps (e.g. Radial piston pump) as very problematic. However, it is easier to use an electrical one Regulate machine. For an electrically controlled pump, experience from the Electro-hydraulic power steering systems can be used. Problematic with an electrically operated pump, however, its relatively high energy consumption, which requires a correspondingly high battery and generator capacity. This problem is reinforced by the fact that larger electric motors in principle are more advantageous since they generally have a longer lifespan.
Elektrische Maschinen in Fahrzeugen sind auch zum Starten von Verbrennungsmotoren als Startergeneratoren, beispielsweise als sogenannte Kurbelwellen-Starter-Generator, kurz KSG, bekannt. Der KSG ist im Antriebsstrang des Fahrzeugs integriert. Er kann zum einen den Verbrennungsmotor starten, und zum anderen im Fahrbetrieb als Generator arbeiten. Die dann erzeugte elektrische Energie kann den verschiedenen elektrischen Verbrauchern im Fahrzeug zur Verfügung gestellt werden oder in den Energiespeicher des Fahrzeugs eingespeist werden. Electrical machines in vehicles are also used to start internal combustion engines as starter generators, for example as so-called crankshaft starter generators, KSG for short, known. The KSG is integrated in the drive train of the vehicle. He can on the one hand start the combustion engine, and on the other hand when driving as Generator work. The electrical energy then generated can be of various types electrical consumers in the vehicle or in the Energy storage of the vehicle can be fed.
Aus der DE 43 42 233 A1 ist eine Ölpumpenantriebsvorrichtung für ein an einen Fahrzeugmotor gekoppeltes Getriebe bekannt. Die Antriebsvorrichtung treibt eine Ölpumpe wahlweise elektrisch über einen Elektromotor oder mechanisch über den Fahrzeugmotor an. Wenn die Drehzahl der Ausgangswelle des Fahrzeugmotors unter einem bestimmten Wert liegt, wird die Ölpumpe über den Elektromotor angetrieben, ansonsten über den Fahrzeugmotor. Da die Pumpe nur oberhalb einer bestimmten Motordrehzahl von dem Fahrzeugmotor angetrieben wird, braucht sie nur so groß dimensioniert sein, dass sie oberhalb dieser Motordrehzahl die erforderliche Arbeitsölmenge fördert. Bei niedrigen Motordrehzahlen hingegen sorgt der Elektroantrieb für die erforderliche Antriebsdrehzahl, d. h. für die eine ausreichende Fördermenge. Im Ergebnis kann dadurch die Pumpe kleiner als herkömmliche Pumpen dimensioniert werden, womit ein geringerer Energieverlust des Getriebes einhergeht. From DE 43 42 233 A1 an oil pump drive device for one to one Vehicle engine coupled transmission known. The drive device drives one Oil pump either electrically via an electric motor or mechanically via the Vehicle engine on. When the speed of the output shaft of the vehicle engine under a certain value, the oil pump is driven by the electric motor, otherwise via the vehicle engine. Because the pump is only above a certain one Engine speed is driven by the vehicle engine, it only needs this large be dimensioned so that they are above the engine speed the required Promotes amount of working oil. At low engine speeds, however, the electric drive ensures for the required drive speed, d. H. for which a sufficient flow rate. in the As a result, the pump can be dimensioned smaller than conventional pumps be, which is associated with a lower energy loss of the transmission.
Nachteilig bei der bekannten Ölpumpenantriebsvorrichtung erweist sich, dass sie zwei Kraftübertragungsmechanismen zum Antrieb über den Elektromotor oder den Fahrzeugmotor erfordert, was relativ aufwendig ist. Weiterhin nachteilig ist die eingeschränkte Regelbarkeit der Ölpumpe, die nur unterhalb einer bestimmten Motordrehzahl über den Elektromotor möglich ist, nicht aber oberhalb dieser Drehzahl bei Antrieb durch den Fahrzeugmotor. A disadvantage of the known oil pump drive device proves that it has two Power transmission mechanisms for driving via the electric motor or Vehicle engine requires what is relatively expensive. Another disadvantage is that limited controllability of the oil pump, which is only below a certain Motor speed is possible via the electric motor, but not above this speed when driven by the vehicle engine.
Aufgabe der vorliegenden Erfindung ist es daher, ein Automatikgetriebe mit einer, unabhängig vom einem Betrieb des Verbrennungsmotors eines Kraftfahrzeugs regelbaren, den Wirkungsgrad des Getriebes verbessernden und über eine effektive Energieversorgung antreibbaren Druckölversorgung zu entwickeln. The object of the present invention is therefore to provide an automatic transmission with a regardless of the operation of the internal combustion engine of a motor vehicle adjustable, improving the efficiency of the transmission and effective Energy supply to develop drivable pressure oil supply.
Die Aufgabe wird erfindungsgemäß in Verbindung mit dem Oberbegriff des Anspruchs 1 dadurch gelöst, dass ein elektrischer Kurbelwellen-Starter-Generator vorgesehen ist, der zwischen der Kurbelwelle und der Kupplung in dem Antriebsstrang des Fahrzeugs angeordnet ist und mit dem der Verbrennungsmotor in einem Starterbetrieb startbar ist, und über den in einem Generatorbetrieb die Ölpumpenantriebsmaschine mit elektrischer Energie versorgbar ist, und dass über das Getriebesteuergerät eine Leistungsregelung des Starter- und Generatorbetriebs des Kurbelwellen-Starter-Generators und eine Leistungsregelung der Ölpumpenantriebsmaschine der Ölpumpe durchführbar ist. The object is achieved in connection with the preamble of claim 1 solved in that an electric crankshaft starter generator is provided which between the crankshaft and the clutch in the drive train of the vehicle is arranged and with which the internal combustion engine can be started in a starter mode, and via the oil pump drive machine with electrical in a generator operation Energy can be supplied and that a power control via the transmission control unit the starter and generator operation of the crankshaft starter generator and one Capacity control of the oil pump drive machine of the oil pump can be carried out.
Der elektrische Ölpumpenantrieb macht einen Betrieb des Getriebes auch bei stehendem Verbrennungsmotor möglich. Insbesondere ist ein sicheres und gefahrloses Abschalten der Verbrennungsmaschine auch während der Ausrollphasen des Fahrzeugs möglich. Der Kurbelwellen-Starter-Generator versorgt im Fahrbetrieb den Ölpumpenantrieb mit elektrischer Energie. Er stellt nicht nur eine sehr viel höhere Leistung zur Verfügung als konventionelle Generatoren, sondern erzeugt diese Leistung auch mit einem wesentlich besseren Wirkungsgrad. Dadurch wird der Ölpumpenantrieb besonders effektiv und kann ausreichend groß ausgelegt werden, um die Ölpumpe permanent anzutreiben ohne die Batteriekapazität zu sehr zu beanspruchen. Durch die Regelung über das Getriebesteuergerät wird einerseits der Starterbetrieb und der Generatorbetrieb des KSG, und andererseits die Förderrate und/oder die Drehzahl der Ölpumpe bedarfsgerecht geregelt. Der verhältnismäßig schlechte Wirkungsgrad der Kette Verbrennungsmotor - KSG - Elektrische Ölpumpenantriebsmaschine - Pumpe wird dabei überkompensiert durch die bedarfsgerechte Ansteuerung der Pumpe. Der tatsächliche benötigte Leistungsbedarf der Pumpe ist wie ausgeführt soviel geringer, als der von einer mechanisch angekoppelten Pumpe bereitgestellte, dass der geringere Wirkungsgrad durch die zweifache Umwandlung trotzdem einen Vorteil bildet, d. h. der Gesamtwirkungsgrad des Getriebes signifikant verbessert wird. The electric oil pump drive also makes the transmission work stationary internal combustion engine possible. In particular, it is safe and secure The internal combustion engine is also switched off during the coasting phases of the vehicle possible. The crankshaft starter generator supplies the Oil pump drive with electrical energy. It not only represents a much higher one Power available than conventional generators, but generates this power also with a much better efficiency. This will drive the oil pump particularly effective and can be designed sufficiently large to accommodate the oil pump to drive continuously without using the battery capacity too much. Through the Regulation via the gearbox control unit is on the one hand the starter operation and the Generator operation of the KSG, and on the other hand the delivery rate and / or the speed of the Oil pump regulated as required. The relatively poor efficiency of the Chain internal combustion engine - KSG - Electric oil pump drive machine - Pump is overcompensated by the need-based control of the pump. The As stated, the actual power requirement of the pump is so much less than the one provided by a mechanically coupled pump that the lower one Nevertheless, efficiency through the double conversion is an advantage, d. H. the Overall efficiency of the transmission is significantly improved.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist eine erste Leistungselektronik für die Leistungsregelung des Starter- und Generatorbetriebs des Kurbelwellen-Starter-Generators und eine zweite Leistungselektronik für die Leistungsregelung der Ölpumpenantriebsmaschine der Ölpumpe vorgesehen. According to a preferred embodiment of the invention is a first Power electronics for the power control of the starter and generator operation of the Crankshaft starter generator and a second power electronics for the Power control of the oil pump drive machine of the oil pump is provided.
Durch die Leistungselektroniken ist es möglich, ein konventionelles Getriebesteuergerät zu verwenden. The power electronics make it possible to use a conventional transmission control unit to use.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist das den Kurbelwellen-Starter-Generator und die elektrische Ölpumpenantriebsmaschine aufweisende Getriebe als ein Doppelkupplungsgetriebe mit einer, im Wesentlichen aus zwei nasslaufenden, ölgekühlten Lamellenkupplungen bestehenden Doppelkupplung, ausgebildet. According to a further preferred embodiment of the invention, this is the Crankshaft starter generator and the electric oil pump drive machine having transmission as a double clutch transmission with one, essentially two wet-running, oil-cooled multi-plate clutches, educated.
Die beschriebene Vorrichtung ist grundsätzlich bei allen Automatikgetrieben einsetzbar. Sie ist jedoch umso effizienter, je größer die Bedarfsleistung an hydraulischer Leistung ist. Insbesondere bei Automatikgetrieben mit Nasskupplung ist sie wegen des Bedarfs an Kühlöl besonders effektiv. Sie ist für den Einsatz in nassen Doppelkupplungsgetrieben besonders vorteilhaft, da die nasse Doppelkupplung verhältnismäßig klein gebaut werden kann, wodurch sich ein ausreichender Bauraum für eine problemlose Integration des KSG in dem Getriebe ergibt. The device described can basically be used in all automatic transmissions. However, the greater the demand for hydraulic power, the more efficient it is is. It is particularly popular with automatic transmissions with wet clutches because of the need Cooling oil particularly effective. It is for use in wet double clutch transmissions Particularly advantageous since the wet double clutch can be built relatively small can, which is sufficient space for a problem-free integration of the KSG results in the transmission.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist der Kurbelwellen- Starter-Generator als eine permanentmagneterregte Synchronmaschine ausgebildet. According to a further preferred embodiment of the invention, the crankshaft Starter generator designed as a permanent magnet synchronous machine.
Diese Ausführung hat den Vorteil, dass aufgrund der Erregung durch Permanentmagnete der Wirkungsgrad dieser Maschine nicht durch Schwingungen und Verlagerungen der Kurbelwelle und damit des Rotors beeinträchtigt wird. This design has the advantage of being excited by permanent magnets the efficiency of this machine is not due to vibrations and displacements Crankshaft and thus the rotor is affected.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist der Kurbelwellen- Starter-Generator anstelle eines der Kupplung vorgelagerten Schwungrads angeordnet und mit der Kurbelwelle fest verbunden, so dass eine Direktstartmethode zum Start des Verbrennungsmotors durchführbar ist. According to a further preferred embodiment of the invention, the crankshaft Starter generator arranged instead of a flywheel upstream of the clutch and firmly connected to the crankshaft, so that a direct start method for starting the Internal combustion engine is feasible.
Der Startergenerator mit Direktstart ist fest mit der Kurbelwelle verbunden. Er wird an Stelle des Schwungrads an der Kurbelwelle vorzugsweise verschraubt. Er erlaubt einen Direktstart, d. h. der Motor wird unmittelbar von dem KSG gestartet, in relativ kurzer Zeit und mit einer sehr hohen Standzeit, d. h. Gesamtbetriebsdauer des Starter, was einen Start-/Stopp-Betrieb, d. h. das Abschalten und wiederholte Starten des Motors, beispielsweise an einer Ampel, ermöglicht. The starter generator with direct start is firmly connected to the crankshaft. He is on Place of the flywheel is preferably screwed to the crankshaft. He allows one Direct start, i.e. H. the engine is started immediately by the KSG, in a relatively short time and with a very long service life, d. H. Total operating time of the starter, what a Start / stop operation, d. H. switching off and restarting the engine, for example at a traffic light.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist der Kurbelwellen- Starter-Generator dem Schwungrad zugeordnet, so dass eine Impulsstartmethode zum Start des Verbrennungsmotors durchführbar ist. According to a further preferred embodiment of the invention, the crankshaft Starter generator assigned to the flywheel, so that a pulse start method for Start of the internal combustion engine is feasible.
Im Gegensatz zu einem Startergenerator mit Direktstart ist ein Startergenerator mit Impulsstart nicht anstelle des Schwungrades eingebaut, sondern mit dem Schwungrad verbindbar. In contrast to a starter generator with direct start, a starter generator is included Impulse start not installed instead of the flywheel, but with the flywheel connectable.
Dabei wird bei abgekoppeltem Verbrennungsmotor von dem Startergenerator das Schwungrad zunächst auf eine Startdrehzahl gebracht und bei dann schnell schließender Kupplung (zwischen Schwungrad und Verbrennungsmotor) der Verbrennungsmotor in Gang gesetzt. Dabei ist erheblich weniger Energie (und damit auch Batteriekapazität) für einen Startvorgang erforderlich. Die Startdrehzahl kann dabei den äußeren Bedingungen entsprechend unterschiedlich gewählt werden. So ist beim Kaltstart eine höhere Startdrehzahl zu wählen. Diese Methode verzögert jedoch den Erststart des Verbrennungsmotors, da das Schwungrad zunächst auf die Startdrehzahl gebracht werden muss, was einerseits mit weniger Leistung als der Direktstart erfolgen soll und andererseits eine höhere Startdrehzahl erfordert, als beim Direktstart. Die Wiederholstarts des Verbrennungsmotors im Start-/Stopp-Betrieb können dagegen schneller ausgeführt werden als mit beim Direktstart, wenn die Drehzahl des Schwungrades während der vorübergehenden Abschaltung des Verbrennungsmotors nicht unter die Startdrehzahl abgesenkt wird. This is when the internal combustion engine is decoupled from the starter generator Flywheel first brought to a starting speed and then quickly closing Coupling (between flywheel and internal combustion engine) the internal combustion engine in Gear set. There is considerably less energy (and thus also battery capacity) for a start process is required. The starting speed can be the external conditions can be selected accordingly differently. So is a higher on cold start Start speed to choose. However, this method delays the first start of the Internal combustion engine, since the flywheel is first brought up to the starting speed must be what should be done with less power than the direct start and on the other hand, requires a higher starting speed than with direct start. The Repeated starts of the internal combustion engine in the start / stop mode, however, can run faster than with direct start if the speed of the Flywheel during the temporary shutdown of the internal combustion engine is not lowered below the starting speed.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist ein elektrischer Energiespeicher des Fahrzeugs derart ausgelegt, dass im Starterbetrieb des Kurbelwellen-Starter-Generators der Direktstart sowohl bei kaltem Verbrennungsmotor, als auch bei betriebswarmem Verbrennungsmotors durchführbar ist. According to a further preferred embodiment of the invention, an electrical Energy storage of the vehicle designed so that the starter operation of the Crankshaft starter generator direct start both when the combustion engine is cold, and can also be carried out when the internal combustion engine is warm.
Durch einen geeigneten Energiespeicher (Batterie mit hoher Leistungsabgabe) wird der Start des Verbrennungsmotors auch bei kaltem Motor (Kaltstart) mit der Direktstartmethode möglich. Auf eine zusätzlich Kaltstartvorrichtung (konventioneller Anlasser) kann dann verzichtet werden. Dies ist besonders günstig für Fahrzeuge, bei denen ein Start-/Stopp-Betrieb vorgesehen ist. With a suitable energy storage (battery with high power output) the Start the internal combustion engine even when the engine is cold (cold start) with the Direct start method possible. On an additional cold start device (more conventional Starter) can then be dispensed with. This is particularly convenient for vehicles at which a start / stop operation is provided.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist die elektrische Ölpumpenantriebsmaschine mit einer Nennleistung ausgelegt, die unterhalb der für die Druckölversorgung maximal erforderlichen Leistung liegt. According to a further preferred embodiment of the invention, the electrical Oil pump drive machine designed with a nominal power below that for the Pressure oil supply is the maximum required power.
Da die maximale Leistung (s. obiges Beispiel) nur während relativ kurzer Zeiträume zur Verfügung gestellt werden muss, kann die elektrische Maschine mit einer energie- und kostensparenden kleineren Nennleistung ausgelegt werden. Sie wird dann, ohne Schaden zu nehmen, für die höheren Leistungsanforderungen kurzzeitig überlastet. Since the maximum output (see example above) is only available for a relatively short period of time The electrical machine can be provided with an energy and cost-saving smaller rated power can be designed. Then it will be without To be damaged, temporarily overloaded for the higher performance requirements.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist über den Kurbelwellen-Starter-Generator zumindest ein Teil der bei einer Abbremsung des Fahrzeugs freigegebenen Bremsenergie, durch Rekuperieren, als elektrische Energie in das Bordnetz oder den Energiespeicher Fahrzeugs einspeisbar. According to a further preferred embodiment of the invention, the Crankshaft starter generator at least part of the braking of the Vehicle released braking energy, by recuperation, as electrical energy in the vehicle electrical system or the energy storage can be fed.
Der KSG ermöglicht eine Bremsenergierückgewinnung (Rekuperieren). Dadurch kann der Wirkungsgrad der Kette Verbrennungsmotor - KSG - Elektrische Ölpumpenantriebsmaschine - Pumpe weiter verbessert werden. The KSG enables braking energy recovery (recuperation). This can the efficiency of the chain internal combustion engine - KSG - electrical Oil pump drive machine - pump to be further improved.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung sind der Kurbelwellen-Starter-Generator und die Ölpumpenantriebsmaschine an ein Bordnetz anpassbar, dessen Betriebsspannung ein Vielfaches von 6 V beträgt. According to a further preferred embodiment of the invention, the Crankshaft starter generator and the oil pump drive machine to an electrical system adaptable, the operating voltage of which is a multiple of 6 V.
Durch die ansteigende Zahl von elektrischen Verbrauchern und deren zunehmende Größe sind in zukünftigen Kraftfahrzeugen in verstärktem Maße Bordnetze mit höheren Spannungen, beispielsweise mit einem 42 V-Bordnetz, zu erwarten. Durch die höhere Bordnetzspannung können die größeren Verbraucher wesentlich effektiver gestaltet werden. Ein Problem aus heutiger Sicht ist dabei die Energiespeicherung. Bekannte Batteriesysteme bieten entweder die Möglichkeit, mit ausreichender Zyklenfestigkeit eine effektive Bremsenergierückgewinnung durch Rekuperieren, Zwischenspeichern und Einspeisen zu realisieren, oder sie ermöglichen den Direktstart, der kurzfristig ganz erhebliche Leistungen erfordert. Batterien, die für den Direktstart gut geeignet sind, sind wiederum weniger als effektive Energiespeicher geeignet. Diese Problematik wird aber durch den steigenden Bordnetzbedarf relativiert. Die generierte Leistung kann zum großen Teil direkt in das Bordnetz eingespeist werden. Die Zwischenspeicherung ist nur erforderlich, wenn die zur Verfügung stehende Leistung (durch Rückgewinnung) den Bedarf übersteigt. Due to the increasing number of electrical consumers and their increasing In future motor vehicles, size will be increasingly on-board networks with higher ones Voltages, for example with a 42 V vehicle electrical system. By the higher one On-board electrical system voltage can make the larger consumers much more effective become. A problem from today's perspective is energy storage. Known Battery systems either offer the option of having a sufficient cycle stability effective braking energy recovery through recuperation, intermediate storage and Realize feed-in, or they enable the direct start, the short term entirely requires substantial performance. Batteries that are well suited for direct start are again less suitable as effective energy storage. This problem will relativized by the increasing on-board electrical system demand. The generated power can be used for a large part can be fed directly into the electrical system. The caching is only required if the available power (through recovery) is Need exceeds.
Die Einsatzmöglichkeiten bei der Verwendung von KSG und elektrischem Ölpumpenantrieb sind durch die Anpassungsmöglichkeit erweitert. Die von dem KSG erzeugte Energie kann von dem elektrischen Ölpumpenantrieb (und anderen Verbrauchern) verwendet werden. Die Batterie kann dann insbesondere für einen Direktstartbetrieb ausgelegt werden. Durch die Möglichkeit der Anpassung, insbesondere an Bordnetze mit höheren Spannungen, kann somit die Effektivität des Zusammenwirkens von KSG und Ölpumpenantrieb beim Einsatz mit einem derartigen Bordnetz weiter verbessert werden. The possible applications when using KSG and electrical Oil pump drives are expanded by the possibility of adaptation. The KSG generated energy can be from the electric oil pump drive (and others Consumers) can be used. The battery can then be used for one Direct start operation can be designed. Due to the possibility of customization, in particular on electrical systems with higher voltages, the effectiveness of the Interaction of KSG and oil pump drive when used with such Vehicle electrical system to be further improved.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung sind die Ölpumpenantriebsmaschine und die Ölpumpe mit einer, für eine aktive Kühlung der Fahrzeugbremsen mit Drucköl angepassten Leistung und Förderrate ausgebildet. According to a further preferred embodiment of the invention, the Oil pump drive machine and the oil pump with one, for active cooling of the Vehicle brakes trained with pressure oil adapted power and delivery rate.
In modernen Fahrzeugen, insbesondere mit einer hohen Motorisierung, kommen verstärkt ölgekühlte Bremsen zur Verwendung. Über die Ölpumpenantriebsmaschine kann diese Kühlung unabhängig vom Verbrennungsmotor optimal eingestellt werden. In modern vehicles, especially those with a high level of motorization, come reinforced oil-cooled brakes for use. About the oil pump drive machine this cooling can be optimally set independently of the internal combustion engine.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung sind die Ölpumpenantriebsmaschine und die Ölpumpe für die Erzeugung eines, für eine Anpresssteuerung für ein CVT-Getriebe angepassten, Öldrucks ausgebildet. According to a further preferred embodiment of the invention, the Oil pump drive machine and the oil pump for producing one, for one Contact control for a CVT gear adapted to oil pressure.
Durch die Auslegung der Ölversorgung insbesondere für hohe Drücke bis zu 80 bar, kann der Anpressdruck, der zur Steuerung eines CVT-Getriebes (Continuous Variable Transmission) erforderlich ist, aufgebracht werden. Bei derartigen stufenlosen Automatikgetrieben erfolgt die Drehmomentübertragung über ein Umschlingungsmittel, beispielsweise eine Stahlkette, die zwischen zwei Kegelscheibenpaaren läuft. Die Übersetzung wird über eine hydraulisch/elektronisch regelbare Anpresskraftsteuerung variiert. Für einen günstigen Wirkungsgrad kommt es darauf an, einerseits einen Leistungsverlust durch Überanpressung der Scheiben und andererseits einen erhöhten Verschleiß durch eine Durchrutschen der Kette zu vermeiden. Der elektrische Ölpumpenantrieb kann die Regelung der Anpresssteuerung hinsichtlich des Wirkungsgrades des Getriebes weiter verbessern. By designing the oil supply especially for high pressures up to 80 bar, can be the contact pressure used to control a CVT transmission (Continuous Variable Transmission) is required to be applied. With such stepless The automatic transmission transmits the torque via a belt, for example a steel chain that runs between two pairs of conical pulleys. The Translation is via a hydraulically / electronically adjustable contact pressure control varied. For a good efficiency, it depends on one hand Loss of performance due to overpressure of the panes and on the other hand an increased Avoid wear caused by the chain slipping. The electric one Oil pump drive can regulate the pressure control with regard to the Further improve the efficiency of the transmission.
Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausführlichen Beschreibung und der beigefügten Zeichnung, in der eine bevorzugte Ausführungsform der Erfindung beispielsweise veranschaulicht ist. Further details of the invention emerge from the following detailed Description and the accompanying drawing, in which a preferred embodiment the invention is illustrated for example.
Es zeigt It shows
Fig. 1 eine schematische Darstellung eines Doppelkupplungsgetriebes mit einem Kurbelwellen-Starter-Generator und einer elektrisch angetriebenen Ölpumpe. Fig. 1 is a schematic representation of a double clutch transmission with a crankshaft starter generator and an electrically driven oil pump.
Ein erfindungsgemäßes Automatikgetriebe weist im Wesentlichen eine regelbare, elektrische Ölpumpenantriebsmaschine 10 (Elektromotor) mit einer Ölpumpe 11 und einen elektrischen Kurbelwellen-Starter-Generator 2 auf. An automatic transmission according to the invention essentially has a controllable, electric oil pump drive machine 10 (electric motor) with an oil pump 11 and an electric crankshaft starter generator 2 .
In Fig. 1 ist eine bevorzugte Ausführungsform mit einem Doppelkupplungsgetriebe 6
schematisch dargestellt. Ein (nicht dargestellter) Verbrennungsmotor treibt über eine
Kurbelwelle 1 den Kurbelwellen-Starter-Generator 2 und über eine Doppelkupplung 5 das
Getriebe 6 und damit das Fahrzeug an. Cer Kurbelwellen-Starter-Generator 2 besteht
aus einem rotierenden Teil 3, dem Rotor und einem stehenden Teil 4, dem Stator. Der
Kurbelwellen-Starter-Generator 2 ist als ein permanentmagneterregte Synchronmaschine
ausgeführt. Ein Getriebesteuergerät 7 steuert eine Leistungselektronik 8 des
Kurbelwellen-Starter-Generator 2 derart an, dass die gewünschte Funktion des Startens
oder Generierens ausgeführt wird. Die Leistung, die der Kurbelwellen-Starter-Generator
2 dem Verbrennungsmotor bzw. dem Fahrzeug entzieht, wird in einen Energiespeicher
15 eingebracht. Gleichzeitig wird von der generierten elektrischen Leistung der benötigte
Strom für die Ölpumpenantriebsmaschine 10 (und ggf. weiterer elektrischer Verbraucher)
abgezweigt. Die Steuerung der Pumpe 11 erfolgt über eine Leistungselektronik 9, die die
Ölpumpenantriebsmaschine 10 der Pumpe 11 ansteuert. Die Pumpe 11 fördert
Getriebeöl (beispielsweise ATF-Öl) aus einem Getriebe(öl)sumpf 12 durch einen Filter
13 in die Druckleitung 14 zur Druckölversorgung eines (hier nicht dargestellten)
Schieberkastens bzw. der hydraulischen Steuerung des Getriebes 6. Hierzu wird das
überschüssige Öl zweckmäßigerweise direkt zur Saugseite der Pumpe zurückgeleitet.
(Würde das Öl in das Getriebe 6 zurückgeleitet, müsste es erneut durch den Filter 13
angesaugt werden. Damit würde sich eine höhere Druckdifferenz vor und nach der
Pumpe 11 einstellen, was zu einer ungünstigen erhöhten Aufnahme von Antriebsleistung
führen würde). Weiterhin fördert die Pumpe 11 das Kühlöl für die Kühlung der nassen
Lamellenkupplungen der Doppelkupplung 5. Das Getriebesteuergerät 7 steuert die
Ölpumpenantriebsmaschine 10 über die Leistungselektronik 9 derart an, dass je nach
Betriebssituation, beispielsweise Ausrollphase an der Ampel bei abgeschaltetem Motor,
Leerlauf, Schaltvorgang, u. s. w., die gerade erforderliche Menge an Getriebeöl durch die
Pumpe 11 gefördert wird, wodurch sich schließlich ein verbesserter günstiger
Wirkungsgrad des Getriebes 6 einstellt.

In Fig. 1, a preferred embodiment with a dual clutch transmission 6 is shown schematically. An internal combustion engine (not shown) drives the crankshaft starter generator 2 via a crankshaft 1 and the transmission 6 and thus the vehicle via a double clutch 5 . Cer crankshaft starter generator 2 consists of a rotating part 3 , the rotor and a standing part 4 , the stator. The crankshaft starter generator 2 is designed as a permanent magnet synchronous machine. A transmission control unit 7 controls power electronics 8 of the crankshaft starter generator 2 in such a way that the desired function of starting or generating is carried out. The power that the crankshaft starter generator 2 extracts from the internal combustion engine or the vehicle is introduced into an energy store 15 . At the same time, the electricity required for the oil pump drive machine 10 (and possibly further electrical consumers) is branched off from the generated electrical power. The control of the pump 11 takes place via a power electronics 9 , which controls the oil pump drive machine 10 of the pump 11 . The pump 11 conveys gear oil (for example ATF oil) from a gear (oil) sump 12 through a filter 13 into the pressure line 14 for supplying pressure oil to a slide box (not shown here) or the hydraulic control of the gear 6 . For this purpose, the excess oil is expediently returned directly to the suction side of the pump. (If the oil were returned to the transmission 6 , it would have to be sucked in again through the filter 13. This would result in a higher pressure difference before and after the pump 11 , which would lead to an unfavorably increased consumption of drive power). The pump 11 also delivers the cooling oil for cooling the wet multi-plate clutches of the double clutch 5 . The transmission control unit 7 controls the oil pump drive machine 10 via the power electronics 9 in such a way that, depending on the operating situation, for example the coasting phase at the traffic lights when the engine is switched off, idling, shifting, etc., the amount of transmission oil that is just required is conveyed by the pump 11 , which ultimately results an improved favorable efficiency of the transmission 6 sets.
