Description

Die Erfindung bezieht sich auf ein Verfahren zur automatischen Auswahl einer Kraftstoffart nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for automatic selection a type of fuel according to the preamble of claim 1.

Ein derartiges Verfahren ist beispielsweise aus der US 5755211 A bekannt. Hierbei findet eine automatische Auswahl einer von zwei Kraftstoffarten lediglich in Abhängigkeit vom erreichten minimal zulässigen Füllstand des jeweiligen Kraftstofftanks statt.Such a method is known for example from US 5755211 A. This automatically selects one of two types of fuel only depending on the minimum permissible fill level of the respective fuel tanks instead.

Zur Senkung der Umweltbelastung können Kraftfahrzeuge allein oder zusätzlich zur Verwendung mit Flüssigkraftstoffen, insbesondere mit Benzin oder Diesel, auch mit umweltverträglicheren gasförmigen Kraftstoffen, insbesondere Erdgas oder Wasserstoff, betrieben werden. Solange kein flächendeckendes Gastankstellennetz verfügbar ist oder der gasförmige Kraftstoff nur in kleineren Mengen im Fahrzeug zur Verfügung steht, können Kraftfahrzeuge für hohe Reichweiten nicht ausschließlich mit gasförmigem Kraftstoff betrieben werden. Bei bekannten sog. Dual-Fuel-Fahrzeugen mit flüssigen und gasförmigen Kraftstoffen wird meist zuerst der gasförmige Kraftstoff verbraucht und nötigenfalls anschließend der flüssige Kraftstoff bis zur nächsten Gastankstelle verwendet.To reduce environmental pollution, motor vehicles can be used alone or in addition to use with liquid fuels, especially gasoline or diesel, even with more environmentally friendly gaseous fuels, especially natural gas or hydrogen. As long as none nationwide gas filling station network is available or the gaseous Fuel can only be available in small quantities in the vehicle Motor vehicles for long ranges not only with gaseous Fuel operated. In known so-called dual-fuel vehicles Liquid and gaseous fuels usually become gaseous first  Fuel is consumed and then, if necessary, the liquid fuel used to the next gas filling station.

Aus der US 3659574 A ist ein Verfahren bekannt, bei dem eine manuelle willkürliche Auswahl einer von zwei Kraftstoffarten (Benzin oder Gas) durch eine Bedienperson ermöglicht wird. Die Bedingung zum Umschalten von einer Kraftstoffart in die andere muß der Fahrer selbst festlegen.From US 3659574 A a method is known in which a manual arbitrary selection of one of two types of fuel (gasoline or gas) an operator is enabled. The condition to switch from the driver must determine one type of fuel into the other.

Die Reichweite mit einer Gasfüllung ist derzeit bei komprimiertem Erdgas z. B. auf 200 km begrenzt. Deshalb muß entweder sehr häufig zu einer Gastankstelle gefahren werden oder der umweltschonende Gasbetrieb wird nicht ausreichend genutzt.The range with a gas filling is currently with compressed natural gas e.g. B. limited to 200 km. Therefore, one must either very often Gas filling station to be driven or the environmentally friendly gas operation underused.

Es ist Aufgabe der Erfindung, ein Verfahren eingangs genannter Art derart zu verbessern, daß trotz einer nur relativ geringen Menge Kraftstoffes für emissionsärmeren Betrieb in einem Kraftfahrzeug mit mindestens zwei Kraftstoffarten eine optimierte, den Betriebsarten und Umgebungsbedingungen angepaßte Nutzung erreicht wird.It is an object of the invention to provide a method of the type mentioned at the outset to improve that despite a relatively small amount of fuel for low-emission operation in a motor vehicle with at least two Fuel types an optimized, the operating modes and Use adapted to environmental conditions is achieved.

Verkehrssituationen, wie Stau oder stop- and-go-Betrieb, sowie Umweltbedingungen, wie Smog oder ortsbezogen ein Stadtgebiet oder eine Kurzone, sein.According to the invention, the method for automatic selection a fuel type for driving a motor vehicle with at least two various selectable types of fuel using an electronic Control unit, the electronic control unit information for Determination of current vehicle environment. The  Vehicle environment can e.g. B. traffic situations such as traffic jams or stop and-go operation, as well as environmental conditions such as smog or location-based Urban area or a short zone.

Eine Brennkraftmaschine kann auch bei Betrieb mit flüssigen Kraftstoffen, insbesondere betriebswarm und mit geregeltem Katalysator, schadstoffarm arbeiten.An internal combustion engine can also operate with liquid fuels, especially warm from operation and with regulated catalyst, low in pollutants work.

Das elektronische Steuergerät ist derart ausgestaltet bzw. programmiert, daß im Falle einer Fahrzeugumgebungsbedingung, die im besonderen Maß eine Schadstoffreduzierung erfordert, automatisch die weniger Emissionen verursachende Kraftstoffart ausgewählt wird.The electronic control device is designed or programmed such that in case of a Vehicle environmental condition, which is a particular degree Pollutant reduction automatically requires less emissions causing fuel type is selected.

Vorzugsweise ist das elektronische Steuergerät ein erweitertes, ohnehin im Fahrzeug vorhandenes Motorsteuergerät, dem üblicherweise Sensorsignale zur Übermittlung von Informationen über die Fahrzeugbetriebsart zur Verfügung stehen.Preferably, the electronic control unit is an expanded one, anyway Vehicle existing engine control unit, which is usually sensor signals to transmit information about the vehicle operating mode To be available.

Durch Auswertung des Verlaufes der Fahrzeuggeschwindigkeit über der Zeit kann das elektronische Steuergerät z. B. stop-and-go-Betrieb selbständig erkennen. Im einfachsten Fall genügen dazu die ohnehin vorhandenen Sensoren, so daß lediglich die Software erweitert werden muß.By evaluating the course of the vehicle speed over time can the electronic control unit such. B. stop-and-go operation independently detect. In the simplest case, the existing ones are sufficient Sensors, so that only the software needs to be expanded.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung erhält das elektronische Steuergerät die Informationen zur Bestimmung der Fahrzeugumgebung durch eine Verbindung zu einem im Kraftfahrzeug vorhandenen Fahrerassistenzsystem. Beispielsweise sind Fahrerassistenzsysteme in Form von Navigationssystemen (z. B. CARIN) oder situationsadaptiven Antriebsmanagement-Systemen (z. B. SAM) bekannt.In a further advantageous embodiment of the invention, the electronic control unit the information to determine the Vehicle environment through a connection to a vehicle existing driver assistance system. For example  Driver assistance systems in the form of navigation systems (e.g. CARIN) or situation-adaptive drive management systems (e.g. SAM) known.

Unter dem Begriff Fahrerassistenzsystem kann sowohl das Gesamt- Fahrerassistenzsystem einschließlich der Anzeige- und/oder Eingabeeinheiten für die Bedienperson oder aber auch nur der interne informationsverarbeitende Teil eines derartigen Gesamt- Fahrerassistenzsystems verstanden werden.Under the term driver assistance system, both the overall Driver assistance system including the display and / or Input units for the operator or just the internal one information processing part of such an overall Driver assistance system can be understood.

Das Fahrerassistenzsystem bzw. das elektronische Steuergerät erhält vorzugsweise die Informationen zur Bestimmung der Fahrzeugumgebung durch eine Funkverbindung zu einem kraftfahrzeugexternen Informationsträger. Derartige Informationsträger sind beispielsweise als Global Positioning System (GPS), Radio Data System (RDS), Traffic Message Channel oder Verkehrsschilder mit elektronischen Sendern bekannt.The driver assistance system or the electronic control unit receives preferably the information for determining the vehicle environment through a radio connection to an external vehicle Information carrier. Such information carriers are, for example, as Global Positioning System (GPS), Radio Data System (RDS), Traffic Message channel or traffic signs with electronic transmitters known.
