Description
Die Erfindung betrifft eine Kraftstofftankanordnung für ein Fahrzeug gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fuel tank arrangement for a vehicle according to the preamble of
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, eine gegenüber dem Stand der Technik verbesserte Kraftstofftankanordnung anzugeben.The invention is based on the object of specifying a fuel tank arrangement which is improved over the prior art.
Die Aufgabe wird erfindungsgemäß durch eine Kraftstofftankanordnung gelöst, welche die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved according to the invention by a fuel tank arrangement which has the features specified in
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.
Eine Kraftstofftankanordnung für ein Fahrzeug umfasst einen Kraftstoffbehälter und einen Drucksensor zur Erfassung eines Drucks innerhalb des Kraftstoffbehälters.A fuel tank arrangement for a vehicle comprises a fuel tank and a pressure sensor for detecting a pressure within the fuel tank.
Erfindungsgemäß ist der Drucksensor derart in dem Kraftstoffbehälter angeordnet, dass sich dieser bei einer definierten Lage des Kraftstoffbehälters im Raum und/oder bei einem definierten Füllstand eines Kraftstoffs im Kraftstoffbehälter unterhalb eines Flüssigkeitsstands des Kraftstoffs befindet.According to the invention, the pressure sensor is arranged in the fuel tank in such a way that it is below a liquid level of the fuel when the fuel tank is in a defined position in space and / or when there is a defined level of fuel in the fuel tank.
Somit wird nicht mehr gefordert, dass sich der Drucksensor in keiner normalen Betriebsposition des Kraftstoffbehälters, welcher beispielsweise als so genannter Drucktank-Kraftstoffbehälter ausgebildet ist, unterhalb des Flüssigkeitsstands des Kraftstoffs befinden darf. Hierdurch kann im Gegensatz zu aus dem Stand der Technik bekannten Lösungen, bei welchem der Drucksensor in einem Bereich in der Mitte des Kraftstoffbehälters, welcher bei allen Fahrzeugneigungen stets in einem Gasraum und nie unterhalb des Flüssigkeitsstands des Kraftstoffs liegt, erreicht werden, dass der Gasraum zur Aufnahme des Drucksensors im Kraftstoffbehälter signifikant verkleinert werden kann, wodurch sich bei gleicher Größe des Kraftstoffbehälters dessen nutzbares Volumen und eine Reichweite des Fahrzeugs vergrößern. Somit kann insbesondere auch bei Plug-In-Hybridfahrzeugen, bei welchen ein Bauraum für einen Kraftstoffbehälter begrenzt ist und welche häufig mit einem Drucktanksystem ausgestattet sind, eine Reichweite erhöht werden. Alternativ kann bei gleichbleibendem nutzbaren Volumen die Größe des Kraftstoffbehälters verringert werden.It is therefore no longer required that the pressure sensor is not allowed to be below the liquid level of the fuel in any normal operating position of the fuel tank, which is designed, for example, as a so-called pressure tank fuel tank. In this way, in contrast to solutions known from the prior art, in which the pressure sensor in an area in the middle of the fuel tank, which is always in a gas compartment regardless of vehicle inclination and never below the liquid level of the fuel, the gas compartment for Recording of the pressure sensor in the fuel tank can be significantly reduced, which increases the usable volume and range of the vehicle for the same size of the fuel tank. In this way, a range can be increased in particular in plug-in hybrid vehicles in which the installation space for a fuel tank is limited and which are often equipped with a pressure tank system. Alternatively, the size of the fuel tank can be reduced with the usable volume remaining the same.
Da sich jedoch somit in bestimmten Betriebssituationen der Drucksensor unterhalb des Flüssigkeitsstands des Kraftstoffs befindet, wirkt neben einem Gasdruck eines im Gasraum befindlichen Gases, insbesondere eines Gases des Kraftstoffs, zusätzlich ein hydrostatischer Druck auf den Drucksensor. Beispielsweise wirkt bei einer Lage des Drucksensors von 5 cm unterhalb des Flüssigkeitsstands ein zusätzlicher hydrostatischer Druck von ca. 4 hPa. Diese Abweichung wird entweder in einer Betriebsstrategie des Drucksensors berücksichtigt, beispielsweise durch Vorgabe eines größeren Toleranzbereichs des Drucksensors, oder der gemessene Druckwert wird über eine Lageerkennung des Fahrzeugs, welche beispielsweise anhand von Beschleunigungssensoren erfasst wird, und über eine Erfassung des Füllstands des Kraftstoffs im Kraftstoffbehälter korrigiert.However, since the pressure sensor is below the liquid level of the fuel in certain operating situations, a hydrostatic pressure acts on the pressure sensor in addition to a gas pressure of a gas in the gas space, in particular a gas in the fuel. For example, if the pressure sensor is 5 cm below the liquid level, an additional hydrostatic pressure of approx. 4 hPa acts. This deviation is either taken into account in an operating strategy of the pressure sensor, for example by specifying a larger tolerance range for the pressure sensor, or the measured pressure value is Position detection of the vehicle, which is detected using acceleration sensors, for example, and corrected by detecting the level of the fuel in the fuel tank.
