Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren zur Bestimmung eines Verbrauchsvorteils durch einen elektrischen Antrieb auf Basis der Bestimmung eines fiktiven Kraftstoffverbrauchs eines konventionellen Antriebs eines Fahrzeugs ermöglicht es demgegenüber, dass ein Fahrer eine Rückmeldung darüber erhält, welchen Kraftstoffverbrauch er durch die Verwendung eines Hybridfahrzeugs mit einem Verbrennungsmotor und einem zusätzlichen Elektromotor einspart. Denn im Allgemeinen wird ein für den Betrieb des Elektromotors vorhandener elektrischer Energiespeicher insbesondere durch eine Rückkopplung von Bewegungsenergie bei einem Bremsvorgang des Fahrzeugs aufgeladen. Ein zusätzlicher Kraftstoffverbrauch entsteht daher bei einem Betrieb des Elektromotors mit derartig gewonnener Antriebsenergie nicht. Um eine Information über einen Verbrauchsvorteil, der sich durch die Verwendung des zusätzlichen elektrischen Antriebs ergibt, einem Fahrer zur Verfügung stellen zu können, wird in erfindungsgemäßer Weise ein fiktiver Kraftstoffverbrauch eines konventionellen Antriebs bestimmt. Aus der angeforderten bzw. tatsächlichen Leistung oder dem jeweiligen Moment wird ein fiktiver Kraftstoffverbrauch für den Fall bestimmt, dass ein Verbrennungsmotor, wie er im Fahrzeug vorhanden ist, die geforderte Leistung bzw. das geforderte Moment liefern würde. Von diesem fiktiven Gesamtverbrauch eines konventionellen Antriebs wird der tatsächliche, momentane Kraftstoffverbrauch des Verbrennungsmotors subtrahiert, um einen Verbrauchsvorteil des elektrischen Antriebs zu erhalten. Ein Verbrauchsvorteil kann somit auf einfache Weise ermittelt werden, um einen Vorteil, den der zusätzliche elektrische Antrieb bietet, zu bestimmen und einem Benutzer zugänglich machen zu können.The inventive method for determining a consumption advantage by an electric Drive based on the determination of a fictitious fuel consumption a conventional drive of a vehicle makes it possible in contrast, that a driver feedback about that which one gets Fuel consumption by the use of a hybrid vehicle saved with an internal combustion engine and an additional electric motor. Because in general, a will for the operation of the electric motor existing electrical energy storage in particular by a feedback charged by kinetic energy during a braking operation of the vehicle. An additional fuel consumption therefore arises during operation of the electric motor with such not obtained drive power. For information about a Consumption advantage resulting from the use of the additional electrical drive results, provide a driver to be able to is in accordance with the invention a fictitious fuel consumption of a conventional drive certainly. From the requested or actual performance or the each moment becomes a fictitious fuel economy in the case determines that an internal combustion engine as it exists in the vehicle is, deliver the required power or the required torque would. From this fictitious total consumption of a conventional drive the actual, subtracts the instantaneous fuel consumption of the internal combustion engine, to obtain a consumption advantage of the electric drive. A consumption advantage can thus be easily determined an advantage that the extra Electric drive offers to diagnose and access to a user to be able to.
Entsprechende Vorteile ergeben sich für eine erfindungsgemäße Auswerteeinrichtung zur Bestimmung eines Verbrauchsvorteils durch einen elektrischen Antrieb auf Basis der Bestimmung eines fiktiven Kraftstoffverbrauchs eines konventionellen Antriebs.Appropriate Benefits arise for an evaluation device according to the invention for determining a consumption advantage by an electric Drive based on the determination of a fictitious fuel consumption a conventional drive.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des in dem unabhängigen Anspruch angegebenen Verfahrens und der in dem unabhängigen Anspruch angegebenen Auswerteeinrichtung möglich. So ist vorteilhaft ein Kennlinienfeld für eine einzuspritzende Kraftstoffmenge unter Berücksichtigung des angeforderten Moments und der jeweiligen Drehzahl des Verbrennungsmotorsantriebs vorhanden. Rechnerisch wird bestimmt, welche Kraftstoffmenge bei einer aktuellen Drehzahl eingespritzt werden müsste, um ein gefordertes Moment liefern zu können. Durch ein Auslesen eines gespeicherten Kennlinienfelds kann eine einzuspritzende Kraftstoffmenge auf einfache Weise bestimmt werden, so dass eine Bestimmung des fiktiven Kraftstoffverbrauchs des Verbrennungsmotorantriebs mit einem geringeren Rechenaufwand ermöglicht wird.By those in the dependent Claims listed measures are advantageous developments and improvements in the independent Claim specified method and in the independent claim specified evaluation possible. So is an advantageous Characteristic field for an amount of fuel to be injected taking into account the requested Moments and the respective speed of the engine drive available. Calculated is determined by what amount of fuel A current speed would have to be injected to deliver a required torque to be able to. By reading a stored characteristic field, a amount of fuel to be injected can be easily determined such that a determination of the fictitious fuel consumption of the engine drive is made possible with a lower computational effort.
Ferner ist es vorteilhaft, bei der Bestimmung des tatsächlichen und des fiktiven Kraftstoffverbrauchs ggf. einen Kalibrierungsfaktor zu berücksichtigen. In den Kalibrierungsfaktor kann beispielsweise eine Umgebungstemperatur des Fahrzeugs, eine Alterung des Verbrennungsmotors, oder auch ein zusätzliches Gewicht des elektrischen Antriebs mit einfließen, um ein möglichst genaues Ergebnis für eine Anzeige des Kraftstoffverbrauchsvorteils durch den zusätzlichen elektrischen Antrieb zu gewährleisten.Further It is beneficial in determining the actual and fictitious fuel consumption if necessary, take a calibration factor into account. In the calibration factor For example, an ambient temperature of the vehicle, a Aging of the internal combustion engine, or an additional Weight of the electric drive to flow in as much as possible exact result for an indication of the fuel economy benefit from the additional to ensure electrical drive.
Vorteilhaft ist in einem Fahrzeug eine Anzeigeeinrichtung vorgesehen, in der der fiktive Kraftstoffverbrauch des elektrischen Antriebs dargestellt wird. Zum einen kann vorteilhaft der aktuelle Kraftstoffverbrauch bei einer momentanen Belastungssituation des Fahrzeugs dargestellt werden. Ferner ist es aber auch vorteilhaft möglich, einen Verbrauchsvorteil integrierend über einen längeren Zeitraum aufzusummieren. Ein diesbezüglicher Zähler kann durch einen Benutzer auf Anforderung ggf. gelöscht werden. Bei einer Aufsummierung über eine längere Zeit kann beispielsweise ermittelt werden, wann sich eventuelle zusätzliche Kosten für den elektrischen Antrieb amortisiert haben. Bei einer Aufsummierung eines Verbrauchsvorteils wird negativ auch ein eventueller, geringer jeweiliger Mehrverbrauch berücksichtigt werden, der in einem Ladebetrieb der Batterie durch eine zusätzliche Belastung des Verbrennungsmotorantriebs durch eine Generatorlast entsteht. Hierdurch kann eine realistische Darstellung auch des aufsummierten Vorteils des Kraftstoffverbrauchs gewährleistet werden.Advantageous in a vehicle, a display device is provided in the the fictitious fuel consumption of the electric drive is shown. On the one hand can advantageously the current fuel consumption a current load situation of the vehicle are displayed. Furthermore, it is also advantageous possible, a consumption advantage integrating over a longer one Accumulate period. A related counter may be provided by a user possibly deleted on request become. When adding up via a longer one For example, time can be determined when any additional costs for have amortized the electric drive. When adding up a Consumption advantage is negative also a possible, lower respective More consumption considered be in a charging operation of the battery by an additional Load of the internal combustion engine drive by a generator load arises. This allows a realistic representation of the accumulated advantage of fuel consumption guaranteed become.
