Die Erfindung betrifft weiterhin eine Vorrichtung zur Regelung eines Generators in einem Zwei-Spannungs-Bordnetz eines Kraftfahrzeuges, mit einem ersten Spannungskreis, dem der Generator zugeordnet ist und dessen Spannungsniveau innerhalb eines Spannungsintervalls abhängig von Betriebsbedingungen des Fahrzeuges variabel regelbar ist und mit einem zweiten Spannungskreis, dessen Spannungsniveau an der unteren Grenze des Spannungsintervalls liegt, mit einem Kondensator der dem ersten Spannungskreis zugeordnet ist und mit einer Fahrzeugbatterie, die dem zweiten Spannungskreis zugeordnet ist, mit einer Kopplungseinrichtung, über die die beiden Spannungskreise gekoppelt sind und die einen Längsregler sowie einen Gleichspannungswandler aufweist, mit einer Rekuperationseinrichtung zur Bremsenergierückgewinnung, und mit einer Regeleinrichtung mit der Lade- und Entladevorgänge des Kondensators regelbar sind.The The invention further relates to a device for controlling a Generator in a two-voltage electrical system of a motor vehicle, with a first voltage circuit to which the generator is assigned and its voltage level within a voltage interval depends on Operating conditions of the vehicle is variably adjustable and with a second voltage circuit whose voltage level at the bottom Limit of the voltage interval is, with a capacitor of associated with the first voltage circuit and with a vehicle battery, which is associated with the second voltage circuit, with a coupling device, via the the two voltage circuits are coupled and the one longitudinal regulator and a DC-DC converter having a recuperation device for Brake Energy Regeneration, and with a control device with the loading and unloading of the Condensers are adjustable.
Die zunehmende Elektrifizierung in Kraftfahrzeugen durch die Einführung technischer Innovationen (Hybridantrieb, Drive-by-wire-Systeme, Start-/Stopp-Systeme (MSA), elektrischer Ventiltrieb, etc.) und Komfortverbesserungen (Klimakompressor, Zusatzheizungen für Innenraum und Fontscheibe, etc.) führen zu einem ständig steigenden Bedarf an elektrischer Leistung der Bordnetze der Kraftfahrzeuge. Während der Grundlastverbrauch an elektrischer Energie bei den heute üblichen Fahrzeugen unter 1 kW liegt, werden in zukünftigen Fahrzeugen Leistungen von über 5 kW benötigt. Derartig hohe Verbrauchsleistungen sind mit dem herkömmlichen 14V-Bordnetz kaum noch realisierbar. Es werden daher höhere Bordnetzspannungen angestrebt. Insbesondere werden derzeit auch 42V/14V-Zwei-Spannungs-Bordnetze favorisiert, um die bereits vorhandenen kostengünstigen 14V-Komponenten weiter verwenden zu können. Zur Erzeugung der höheren elektrischen Leistungen werden stärkere Generatoren benötigt. Diese Generatoren (und andere Nebenaggregate) führen jedoch zu einer signifikanten Erhöhung des Kraftstoffverbrauchs. Daher sind bereits intelligente Generatorregelungen mit variabler Generatorspannung vorgeschlagen worden, um den Generator verbrauchsoptimiert zu betreiben. Es sind auch Rekuperationseinrichtungen bekannt; die einen Teil der Bremsenergie über den Generator oder, in Hybridfahrzeugen, über eine elektrische Maschine, die wechselweise als Motor und als Generator betrieben werden kann, als elektrische Energie zurückgewinnen, um das Bordnetz zu unterstützen und einen oder mehrere Energiespeicher aufzuladen.The increasing electrification in motor vehicles through the introduction of technical Innovations (hybrid drive, drive-by-wire systems, start / stop systems (MSA), electric valve train, etc.) and comfort improvements (air conditioning compressor, auxiliary heaters for interior and font wheel, etc.) to one constantly increasing demand for electric power of the vehicle electrical system. While the base load consumption of electrical energy in today's usual Vehicles below 1 kW will be used in future vehicles from above 5 kW needed. Such high consumption rates are with the conventional 14V electrical system hardly realizable. Therefore, higher on-board voltages are desired. In particular, currently also 42V / 14V two-voltage vehicle electrical systems favors to continue to use the already existing inexpensive 14V components to be able to. To generate the higher electrical Achievements become stronger Generators needed. However, these generators (and other ancillaries) lead to a significant increase of fuel consumption. Therefore, already intelligent generator regulations With variable generator voltage has been proposed to the generator to operate with optimized fuel consumption. There are also recuperation facilities known; a part of the braking energy through the generator or, in Hybrid vehicles, about an electric machine that alternately as a motor and as a generator can be operated as recovering electrical energy, to support the electrical system and to charge one or more energy stores.

Weiterhin ist in dem ersten Spannungskreis ein Kondensator vorgesehen, beispielsweise ein SuperCap, mittels dessen im Schubbetrieb des Kraftfahrzeuges Bremsenergie rekuperiert wird. Dabei wird der Kondensator auf den Wert des ersten Spannungsniveaus aufgeladen. Die Kapazität des geladenen Kondensators steht dann dem Bordnetz zur Verfügung, insbesondere um einen Spitzenverbrauch abzupuffern. Üblicherweise wird der Kondensator immer, wenn die an ihm anliegende Spannung höher ist als eine (Mindest-) Eingangsspannung des DC/DC-Wandlers und nicht die Bedingungen für eine Rekuperation erfüllt sind, entladen.Farther a capacitor is provided in the first voltage circuit, for example a SuperCap, by means of which in the overrun mode of the motor vehicle Braking energy is recuperated. The capacitor is on the Value of the first voltage level charged. The capacity of the charged Capacitor is then available to the electrical system, in particular a To buffer peak consumption. Usually the capacitor will always be when the voltage applied to it is higher than a (minimum) input voltage of the DC / DC converter and not the Conditions for a recuperation met are unloaded.
Nachteilig wirkt sich bei den intelligenten Generatorregelungen der bekannten Art ihre Entladestrategie aus, die zur Folge hat, dass der Kondensator häufig vollständig entladen ist. Die Leistung des Generators ist vom Spannungsniveau des ersten Spannungskreises und damit von der Spannung, die am SuperCap anliegt, abhängig. Durch eine Anhebung des ersten Spannungsniveaus über die Generatorregelung kann somit die Generatorleistung erhöht werden. Die Dynamik des Generators wird durch Zuschalten der Kapazität verbessert, da die Erregerwicklung schneller geladen werden kann. Eine schlagartige Erhöhung des Spannungsniveaus ist jedoch wegen des begrenzten Generatorstroms nicht möglich. Dies kann in bestimmten Betriebssituationen, insbesondere bei hohen anfallenden Rekuperationsenergien dazu führen, dass ein Überschuss an Bremsenergie entsteht, der nicht für das Bordnetz nutzbar ist, weil der anfänglich niedrige Ladezustand des Kondensators die Generatorspannung zunächst begrenzt. Der niedrige Ladezustand des Kondensators wirkt sich daher negativ auf das Rekuperationspotenzial aus. Während eines Bremsvorgangs, d.h. während einer Rekuperationsphase ist somit eine höhere Generatorleistung zur Ausnutzung der rekuperierten Energie und zur Erhöhung der Bremswirkung des Motors wünschenswert.adversely affects the intelligent generator regulations of the known Their discharge strategy, which has the consequence that the capacitor often completely discharged is. The power of the generator is from the voltage level of the first Voltage circuit and thus the voltage applied to the SuperCap dependent. By raising the first voltage level via the generator control can thus increasing the generator power become. Dynamics of the generator are improved by adding capacity because the excitation winding can be charged faster. A sudden increase the voltage level, however, is because of the limited generator current not possible. This can be in certain operating situations, especially at high levels accumulating recuperation energies cause a surplus braking energy is generated, which is not usable for the vehicle electrical system, because of the initial low charge state of the capacitor initially limits the generator voltage. The low charge state of the capacitor therefore has a negative effect on the recuperation potential. During a braking process, i.e. while a recuperation phase is thus a higher generator power to Utilization of the recuperated energy and to increase the braking effect of the engine desirable.
Aufgabe der vorliegenden Erfindung ist es daher, die bekannte intelligente Generatorregelung in einem Zwei-Spannungsbordnetz so weiter zu entwickeln, dass die bei einer Rekuperation frei werdende Bremsenergie effektiver ausgenutzt wird.task The present invention is therefore the well-known intelligent So to further develop generator control in a two-voltage on-board network that the released during a recuperation braking energy more effective is exploited.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruches 1 dadurch gelöst, dass mit Hilfe der Entladeregelung eine Kondensatorspannung als ein Startwert für einen nachfolgenden Ladevorgang des Kondensators während einer Rekuperationsphase eingestellt wird, die in Abhängigkeit einer Fahrzeuggeschwindigkeit, mit der sich das Fahrzeug zu Beginn der Rekuperationsphase fortbewegt, bestimmt wird.These The object is in connection with the preamble of claim 1 solved by that by means of the discharge control a capacitor voltage as a starting value for a subsequent charging of the capacitor during a Recuperation phase is set, which depends on a vehicle speed, with which the vehicle moves at the beginning of the recuperation phase, is determined.
Weitere Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zu schaffen, mit der ein effizientere intelligente Generatorregelung möglich ist.Further The object of the present invention is to provide a device with which a more efficient intelligent generator control is possible.
Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Anspruches 6 dadurch gelöst, dass die Regeleinrichtung Mittel aufweist, mit denen eine von der Fahrzeuggeschwindigkeit abhängige Kondensatorspannung als ein Startwert für einen nachfolgenden Ladevorgang des Kondensators während einer Rekuperationsphase ermittelbar und einstellbar ist.These The object becomes in connection with the preamble of claim 6 solved by in that the control device has means with which one of the Vehicle speed dependent Capacitor voltage as a starting value for a subsequent charging process of the capacitor during a Recuperation phase can be determined and set.
Der Erfindung liegt die Erkenntnis zugrunde, dass ein eindeutiger Zusammenhang zwischen der Fahrgeschwindigkeit und der Bremsleistung, bzw. Bremsenergie besteht. Dies ist bei Kundenfahrten und Tests aufgefallen. Insbesondere sind bei hohen Geschwindigkeiten sowohl erheblich höhere Bremsleistungen als auch Bremsenergien zu erwarten. Um bei niedrigen Geschwindigkeiten eine möglichst hohe Generatorleistung für eine effektivere Rekuperation zur Verfügung zu haben, ist es daher vorteilhaft, den jeweiligen Ladevorgang des Kondensators, abhängig von der Geschwindigkeit, bei einer höheren Kondensator-Spannung zu beginnen. Dabei wird zwar auf einen Speicheranteil des Kondensators verzichtet. Die mögliche Generatorleistung und damit der Anteil an rekuperierter Bremsenergie wird jedoch erhöht, d.h. ein höherer Anteil an Bremsenergie wird in elektrische Energie umgewandelt, die dem Bordnetz zur Versorgung elektrischer Verbraucher und zur Aufladung von Fahrzeugbatterie sowie Kondensator zur Verfügung gestellt wird. Dadurch wird der Antriebsmotor des Fahrzeugs durch eine höhere Entlastung des Generators außerhalb des Rekuperationsbetriebes entlastet, wodurch eine Kraftstoffersparnis erzielt wird.Of the Invention is based on the finding that a clear connection between the driving speed and the braking power, or braking energy consists. This has been noticed in customer trips and tests. Especially are at high speeds both significantly higher braking performance as well as braking energies. At low speeds one possible high generator power for It is therefore a more effective recuperation available advantageous, the respective charging of the capacitor, depending on the speed, at a higher Capacitor voltage to start. It is indeed on a memory share omitted the capacitor. The possible generator power and however, the proportion of recuperated braking energy is increased, i. e. one higher Proportion of braking energy is converted into electrical energy, the on-board network for the supply of electrical consumers and the Charging of vehicle battery as well as capacitor provided becomes. As a result, the drive motor of the vehicle by a higher discharge of the Generator outside Relieves the recuperation, thereby saving fuel is achieved.
Unter der Annnahme, dass während der Rekuperationsphasen die Geschwindigkeit fällt und außerhalb der Rekuperationsphasen die Geschwindigkeit gleich bleibt oder steigt sowie dass die optimale Ladespannung mit zunehmender Geschwindigkeit monoton fällt, kann die optimale Ladespannung, ausgehend von einer ausreichend hohen Anfangsspannung, immer durch Entladen eingestellt werden. D.h. im Fahrbetrieb wird der Kondensator nicht automatisch komplett entladen, wenn die an ihm anliegende Spannung höher ist als die Eingangsspannung am Gleichstromwandler; sondern es wird eine Ladespannung entsprechend der aktuellen Geschwindigkeit vorgehalten. Die Geschwindigkeit, bei der die nächste Rekuperationsphase beginnt, muss dafür also nicht bekannt sein. Außerdem ist es ausgeschlossen, dass der Kondensator außerhalb der Rekuperationsphasen aufgeladen werden muss, um die optimale Ladespannung zu erreichen.Under the acceptance that during the recuperation phases the velocity falls and outside the Rekuperationsphasen the speed stays the same or increases as well as that the optimal charging voltage monotonically falling with increasing speed, the optimum charging voltage, starting from a sufficiently high initial voltage, always through Unloading can be set. That while driving is the capacitor not fully discharged automatically when the voltage applied to it is higher as the input voltage to the DC-DC converter; but it will a charging voltage according to the current speed held. The speed at which the next recuperation phase begins so have to not known. Furthermore it is excluded that the capacitor is outside of the recuperation phases must be charged in order to achieve the optimum charging voltage.
Mit diesen Annahmen ist es möglich, wie bei einer bevorzugten Ausführungsform der Erfindung vorgesehen, mit Hilfe einer von der Kapazität des Kondensators, d.h. von der jeweiligen Kondensatorgröße abhängigen Kondensatorspannung/Fahrzeuggeschwindigkeits- Kennlinie, die innerhalb des Spannungsintervalls des ersten Spannungskreises verläuft, für jede Geschwindigkeit, bei der eine Rekuperation einsetzt, eine optimale Kondensator-Startspannung, d.h. ein Startpunkt oder Startbereich, finden, der die Energiezufuhr (Ladeleistung × Ladezeit) in den Speicher maximiert. Diese Startspannung wird bei der Entladeregelung des Kondensators im Fahrbetrieb berücksichtigt.With these assumptions it is possible as in a preferred embodiment of the invention, by means of one of the capacitance of the capacitor, i.e. Capacitor voltage / vehicle speed dependent on the respective capacitor size. Characteristic curve within the voltage interval of the first voltage circuit runs, for every Speed at which a recuperation sets in, an optimal Capacitor start voltage, i. a starting point or starting area, find the energy supply (charging power × charging time) in the memory maximized. This starting voltage is at the discharge of the Condenser considered while driving.
Grundsätzlich ist die erfindungsgemäße Entladeregelung in allen Bordnetzen mit Generatoren mit variabler Spannung (Multi-Voltage-Generatoren, kurz MVG) einsetzbar.Basically the unloading control according to the invention in all on-board networks with generators with variable voltage (multi-voltage generators, short MVG) can be used.
Zur Verifizierung der erfindungsgemäßen Laderegelung ist es besonders vorteilhaft, wie bei einer weiteren bevorzugten Ausführungsform der Erfindung vorgesehen, den Neuen Europäischen Fahrzyklus (NEFZ) für Pkw durchzuführen. Dadurch steht ein standardisiertes Prüfverfahren zur Verfügung, eine hinsichtlich Rekuperation und Kraftstoffverbrauch sowie Schadstoffemission optimierte Entladestrategie unter Berücksichtigung der erfindungsgemäßen geschwindigkeitsabhängigen Ladespannung für verschiedene Kondensatorgrößen und Bordnetztopologien zu finden.to Verification of the charge control according to the invention it is particularly advantageous, as in another preferred embodiment The invention provides for the New European Driving Cycle (NEDC) for passenger cars. Thereby is a standardized test procedure available, one in terms of recuperation and fuel consumption as well as pollutant emission optimized discharge strategy taking into account the inventive speed-dependent charging voltage for various Capacitor sizes and To find on-board network topologies.
