  • Navigations-Einrichtungen sind aus dem Stand der Technik bekannt. Navigation devices are known from the prior art. Eine Navigations-Einrichtung ist ein IT-gestütztes technisches System, das mit Hilfe von Positionsbestimmung (Satellit, Funk, GSM bzw. inertes oder autonomes System) und Geoinformationen (Topologie-, Straßen-, Luft- oder Seekarten) eine Zielführung zu einem gewählten Ort oder eine Route unter Beachtung gewünschter Kriterien ermöglicht. A navigation device is an IT-based technical system, which with the aid of position determination (satellite, radio, GSM or inert or autonomous system) and geographic information (topology, road, air or sea maps) a route guidance to a selected location permits or route in accordance with the desired criteria.
  • Insbesondere bei elektrisch betriebenen Fahrzeugen kommt es zu der Problematik, dass das Fahrzeug bei Unterschreiten einer bestimmten Reichweitenschwelle aufgeladen werden muss. In particular, in electrically operated vehicles, there is the problem that the vehicle needs to be charged at below a certain threshold range.
  • Die The DE 103 02 504 A1 DE 103 02 504 A1 betrifft ein Verfahren zum Ermitteln der Reichweite eines Elektrofahrzeuges. relates to a method for determining the range of an electric vehicle. Sollten die vom Fahrer gewünschten Komfortfunktionen den Vorrat an elektrischer Energie zu sehr angreifen, so erhält er eine diesbezügliche Information von dem Fahrzeugcomputer, so dass er seine Komfortwünsche auf das zur Erreichung des Wegzieles notwendige Maß reduzieren kann. If desired by the driver comfort functions too much attack the supply of electrical energy, so he receives a relevant information from the vehicle computer so that it can reduce its comfort requirements to what is necessary to achieve the Wegzieles measure. Der Fahrzeugcomputer bzw. der Fahrzeugführer kann eine Fahrkomfortfunktion beispielsweise dann abschalten oder eine solche Abschaltung anregen, wenn eine für eine Wegstrecke aktuell errechnete Restreichweite des Elektrofahrzeuges zur Zielerreichung nicht ausreicht oder das elektrische Bordnetz diese starke Belastung nicht verträgt. The vehicle computer or the vehicle driver can, for example, then switch off a driving comfort function or stimulate such a shutdown, if a currently calculated for a distance remaining range of the electric vehicle to achieve these goals is insufficient or the electrical system does not tolerate those high load.
  • DE 19807291 A1 DE 19807291 A1 betrifft ein Verfahren, bei dem mittels eines Positionssensors eine momentane Position des Kraftfahrzeuges ermittelt und mit gespeicherten Daten einer Straßen- oder Landkarte verglichen werden kann. relates to a method, can be determined by in which of a position sensor a present position of the vehicle and compared with stored data of a road or map. Durch den Vergleich wird festgestellt, in welcher Verkehrsumgebung sich das Fahrzeug befindet. By comparing is found in what traffic around the vehicle is. Ferner wird ein entsprechender vorbestimmter Betriebsmodus des Hybridantriebs für die jeweilige Verkehrsumgebung eingestellt. Further, a corresponding predetermined operating mode of the hybrid drive for the respective traffic environment is set. Außerdem ist vorgesehen, dass im reinen Elektromotorbetrieb in einem Stadtverkehr bei einem vorbestimmten Entladezustand einer Batterie des Hybridantriebs eine Warnung an einen Fahrer abgegeben wird und in Abhängigkeit von der ermittelten Position des Kraftfahrzeuges beispielsweise der Vorschlag gegeben wird: ”Anfahren der nächsten Elektrotankstelle”, falls sich wenigstens eine Elektrotankstelle innerhalb der verbleibenden Reichweite des Elektromotorbetriebes befindet. In addition, it is provided that a warning to a driver, in a city traffic at a predetermined discharge status of a battery of the hybrid drive given in electric motor operation and, for example, the proposal is given as a function of the determined position of the vehicle: "starting the next Elektrotankstelle" If at least one electric gas station within the remaining range of the electric engine operation is located.
  • Die Aufgabe der Erfindung besteht darin, eine Navigations-Einrichtung bereitzustellen, welche einen zuverlässigen Schutz vor einer eventuellen Reichweiten-Problematik gewährleistet. The object of the invention is to provide a navigation device which guarantees reliable protection against a possible range problem.
  • Diese Aufgabe wird erfindungsgemäß durch eine Navigations-Einrichtung mit den Merkmalen des Anspruchs 1 gelöst. This object is inventively achieved by a navigation device having the features of claim 1.
  • Weitere vorteilhafte Merkmale beinhalten die Unteransprüche. Other advantageous features include the sub-claims.
  • Die erfindungsgemäße Navigations-Einrichtung sieht eine Berechnung und Überwachung des für die jeweilige Reichweite notwendigen Energiegehaltes eines Antriebs-Energiespeichers vor, wobei bei Unterschreiten der zur Verfügung stehenden Reichweite gegenüber dem Abstand zum eingegebenen Navigationsziel die nächste erreichbare Elektro-Tankstelle als Ziel bzw. Zwischenziel bestimmt bzw. eingesetzt wird. The navigation device according to the invention provides for a calculation and monitoring of the necessary for the particular range of energy content of a drive energy store, wherein when falling short of the available range compared to the distance to the input navigation destination, the next available electric gas station as a destination or intermediate destination determined or . is used. Insbesondere handelt es sich bei dem Antriebs-Energiespeicher um eine Batterie. In particular, when the driving energy store is a battery. Der Fahrer muss sich somit aufgrund des Energievorrates keine Gedanken über die Erreichbarkeit der nächsten Tankstelle machen, sondern wird, ohne diesbezüglich Aktionen ausüben zu müssen, vor Unterschreiten einer kritischen Reichweitenschwelle zu einer Tankstelle geleitet. The driver must therefore be due to the energy reserve not worry about the location of the nearest gas station to make but is without this regard exert actions directed against falling below a critical threshold range to a gas station.
  • Eine Ausführungsform sieht vor, dass ein selbsttätiges Umstellen des Navigationszieles mittels der Navigations-Einrichtung erfolgt. One embodiment provides that an automatic switching the navigation destination by means of the navigation device. Die Navigations-Einrichtung sucht in Abhängigkeit der Reichweitenschwelle automatisch die nächstgelegene Tankstelle auf und stellt vorzugsweise die verfügbare Reichweite der Entfernung zu dieser Tankstelle gegenüber. The navigation device automatically searches depending on the coverage threshold the nearest petrol station and preferably, the available range of the distance to the petrol station opposite. Wenn erkannt wird, dass sich die Reichweite der Entfernung zu der Tankstelle annähert, wird automatisch das ursprüngliche Navigationsziel auf die nächste Tankstelle (Elektrotankstelle) umgesetzt bzw. die letzte eingegebene Route um die Angabe der Tankstelle als Zwischenziel erweitert. If it is recognized that the range of the distance closer to the gas station, the original navigation destination to the next gas station (electric station) is automatically implemented or the last entered route expanded to include the specification of the gas station as a stopover.
  • Vorzugsweise weist die Navigations-Einrichtung eine Speichereinrichtung für die im Bereich der Reichweite liegenden Elektro-Tankstellen auf. Preferably, the navigation device has a memory device for the lying in the region of the reach-electric stations. Beispielsweise kann automatisch die nächste zu erreichende Tankstelle als Zwischenziel eingefügt werden oder die in Abhängigkeit des Energieinhaltes und der verfügbaren Reichweite letzte noch zu erreichende Tankstelle. For example, can be inserted as an interim destination or last depending on the energy content and the available range yet to be reached petrol station automatically the next-to-reach gas station.
  • Beispielsweise kann eine, insbesondere fortlaufende, Berechnung und/oder Anzeige der jeweils aufgrund des überwachten Energieinhaltes errechneten, noch verbleibenden Fahrtstrecke erfolgen. For example, one, in particular continuous, calculation and / or display the calculated respectively due to the monitored energy content, remaining route take place. Beispielsweise kann in Abhängigkeit der noch verbleibenden Fahrtstrecke die Liste der noch zu erreichenden Tankstellen ständig aktualisiert bzw. geprüft werden. For example, depending on the remaining route, the list of yet-to-reach gas stations can be constantly updated and tested. Die Bestimmung der in Abhängigkeit von Reichweite/Entfernung und Energieinhalt ermittelte am besten gelegene Tankstelle kann von der Navigations-Einrichtung automatisch vorgenommen und als Zwischenziel in die eigentliche Route übernommen werden. The determination of the function of range / distance and energy content determined best located gas station can be automatically set by the navigation device and set as the stopover in the actual route.
  • Eine weitere Ausführungsform sieht vor, dass zumindest eine aufgrund der Auswertung des Energieinhaltes und des Abstands zur nächsten Elektro-Tankstelle vorgesehene reichweitenverlängernde Maßnahme vorgesehen sein kann. Another embodiment provides that at least one provided based on the evaluation of the energy content and the distance to the nearest gas station electric reichweitenverlängernde measure can be provided. Diese Maßnahme kann ebenfalls automatisch von der Navigations-Einrichtung eingeleitet und an entsprechende Steuergeräte im Elektro-Fahrzeug weitergeben werden. This measure can also be initiated automatically by the navigation device and share it with appropriate control devices in electric vehicle. Selbstverständlich können die vom System vorgeschlagenen bzw. eingeleiteten reichweitenverlängernden Maßnahmen jederzeit vom Fahrer unterbunden bzw. in deren Auswahl und/oder Reihenfolge abgeändert werden. Of course, the proposed or initiated by the system range-contempt longer measures can always stopped by the driver or be modified in the selection and / or order.
  • Beispielsweise kann dabei eine in der Reduzierung eines elektrischen Verbrauchers und/oder Leistungsbeschränkung des Elektrofahrzeuges liegende Maßnahme vorgesehen sein. For example, a measure lying in the reduction of an electrical load and / or power constraint of the electric vehicle can be provided. Beispielsweise kann der Fahrer die Betriebsweise des Elektrofahrzeuges, insbesondere durch eine Veränderung des Fahrstils, wechseln (beispielsweise von sportlich auf ökonomisch) oder er kann die Anzahl der aktivierten Geräte reduzieren, die den Fahrkomfort verbessern (beispielsweise Klimaanlage oder Heizung). For example, the driver can the operation of the electric vehicle, in particular by a change in driving style, change (for example, from sporty to economical) or it can reduce the number of activated devices that improve ride comfort (eg air conditioning or heating).
