Description

Die Erfindung bezieht sich auf eine Navigations-Einrichtung nach dem Patentanspruch 1.The invention relates to a navigation device according to claim 1.

Navigations-Einrichtungen sind aus dem Stand der Technik bekannt. 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.Navigation devices are known in the art. A navigation device is an IT-based technical system that uses positioning (satellite, radio, GSM or inert or autonomous system) and geographic information (topology, road, air or sea charts) to guide you to a selected location or a route allowing for the desired criteria.

Insbesondere bei elektrisch betriebenen Fahrzeugen kommt es zu der Problematik, dass das Fahrzeug bei Unterschreiten einer bestimmten Reichweitenschwelle aufgeladen werden muss.Particularly in the case of electrically powered vehicles, there is the problem that the vehicle must be charged when falling below a certain range threshold.

Die DE 103 02 504 A1 betrifft ein Verfahren zum Ermitteln der Reichweite eines Elektrofahrzeuges. 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. 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 DE 103 02 504 A1 relates to a method for determining the range of an electric vehicle. If the comfort functions desired by the driver attack the supply of electrical energy too much, he receives information in this regard from the vehicle computer, so that he can reduce his comfort wishes to the level necessary for achieving the travel goal. The vehicle computer or the driver can, for example, then switch off a ride comfort function or initiate such a shutdown if an actual range of the electric vehicle for achieving a distance is insufficient to achieve the target or the electrical system does not tolerate this heavy load.

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. Durch den Vergleich wird festgestellt, in welcher Verkehrsumgebung sich das Fahrzeug befindet. Ferner wird ein entsprechender vorbestimmter Betriebsmodus des Hybridantriebs für die jeweilige Verkehrsumgebung eingestellt. 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. DE 19807291 A1 relates to a method in which by means of a position sensor, a current position of the motor vehicle can be determined and compared with stored data of a road or map. The comparison determines in which traffic environment the vehicle is located. Furthermore, a corresponding predetermined operating mode of the hybrid drive is set for the respective traffic environment. It is also provided that in pure electric motor operation in a city traffic at a predetermined discharge state of a battery of the hybrid drive a warning is delivered to a driver and given as a function of the determined position of the motor vehicle, for example, the proposal: "approach the next electric filling station", if at least one electric filling station is located within the remaining range of the electric motor operation.

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 ensures 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 achieved by a navigation device with the features of claim 1.

Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.Further advantageous features include the subclaims.

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. Insbesondere handelt es sich bei dem Antriebs-Energiespeicher um eine Batterie. 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 navigation device according to the invention provides for a calculation and monitoring of the energy content of a drive energy store necessary for the respective range, whereby when the available range is less than the distance to the entered navigation destination, the next reachable electric filling station is determined as destination or intermediate destination is used. In particular, the drive energy store is a battery. The driver does not have to worry about the accessibility of the next gas station because of the energy supply, but, without having to act in this regard, is directed to a gas station before falling below a critical range threshold.

Eine Ausführungsform sieht vor, dass ein selbsttätiges Umstellen des Navigationszieles mittels der Navigations-Einrichtung erfolgt. 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. 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.An embodiment provides that an automatic changeover of the navigation destination takes place by means of the navigation device. The navigation device automatically searches the nearest gas station depending on the range threshold and preferably compares the available range to the distance to that gas station. If it is detected that the range approaches the distance to the gas station, the original navigation destination is automatically converted to the next gas station (electric filling station) or the last entered route is expanded to include the gas station as an intermediate destination.

Vorzugsweise weist die Navigations-Einrichtung eine Speichereinrichtung für die im Bereich der Reichweite liegenden Elektro-Tankstellen auf. 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.The navigation device preferably has a storage device for the electric filling stations located in the region of the range. For example, the next gas station to be reached can automatically be inserted as an intermediate destination or the last gas station to be reached depending on the energy content and the available range.

Beispielsweise kann eine, insbesondere fortlaufende, Berechnung und/oder Anzeige der jeweils aufgrund des überwachten Energieinhaltes errechneten, noch verbleibenden Fahrtstrecke erfolgen. Beispielsweise kann in Abhängigkeit der noch verbleibenden Fahrtstrecke die Liste der noch zu erreichenden Tankstellen ständig aktualisiert bzw. geprüft werden. 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.For example, a, in particular continuous, calculation and / or display of the calculated in each case due to the monitored energy content, still remaining distance traveled. For example, depending on the remaining journey, the list of gas stations still to be reached can be constantly updated or checked. The determination of the best located depending on range / distance and energy content gas station can be made automatically by the navigation device and adopted as an intermediate goal 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. Diese Maßnahme kann ebenfalls automatisch von der Navigations-Einrichtung eingeleitet und an entsprechende Steuergeräte im Elektro-Fahrzeug weitergeben werden. Selbstverständlich können die vom System vorgeschlagenen bzw. eingeleiteten reichweitenverlängernden Maßnahmen jederzeit vom Fahrer unterbunden bzw. in deren Auswahl und/oder Reihenfolge abgeändert werden. A further embodiment provides that at least one range-extending measure provided on the basis of the evaluation of the energy content and the distance to the next electric filling station can be provided. This measure can likewise be initiated automatically by the navigation device and passed on to corresponding control devices in the electric vehicle. Of course, the system proposed or introduced range-extending measures can be prevented at any time by the driver or modified in their selection and / or order.

Beispielsweise kann dabei eine in der Reduzierung eines elektrischen Verbrauchers und/oder Leistungsbeschränkung des Elektrofahrzeuges liegende Maßnahme vorgesehen sein. 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, a measure lying in the reduction of an electrical load and / or power limitation of the electric vehicle may be provided. For example, the driver may change the mode of operation of the electric vehicle, in particular by changing the driving style (for example, from sporty to economical) or may reduce the number of activated devices that improve ride comfort (eg, air conditioning or heating).

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der unter Bezugnahme auf die Zeichnung ein Ausführungsbeispiel der Erfindung beschrieben ist. Dabei können die in den Ansprüchen und in der Beschreibung erwähnten Merkmale jeweils einzeln für sich oder in beliebiger Kombination erfindungswesentlich sein.Further advantages, features and details of the invention will become apparent from the following description in which an embodiment of the invention is described with reference to the drawings. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination.

Die Erfindung wird nachfolgend mit Bezug auf die einzige Zeichnung näher erläutert.The invention will be explained in more detail with reference to the single drawing.

Die einzige Figur (1) zeigt eine schematisch dargestellte, zu einer Navigations-Einrichtung gehörende, Navigations-Einheit 1. Die Navigations-Einheit 1 umfasst ein Display 2 auf dem eine eingegebene bzw. zurückzulegende Route 3 angezeigt und dem Fahrer sowohl optisch als auch über entsprechende Mittel akustisch mitgeteilt werden kann.The only figure ( 1 ) shows a schematically illustrated, belonging to a navigation device, navigation unit 1 , The navigation unit 1 includes a display 2 on the one entered or zurückzulegende route 3 displayed and the driver can be communicated acoustically both visually and via appropriate means.

Die Navigations-Einrichtung umfasst eine, in einem Speicher abgelegte, Liste mit Elektrotankstellen für das Elektrofahrzeug. Zudem verfügt das Elektrofahrzeug über eine Reichweiten-Überwachung, welche den Energieinhalt des elektrischen Energiespeichers überwacht und fortlaufend berechnet, welche Strecke das Elektrofahrzeug mit diesem Energieinhalt noch zurücklegen kann. Diese Informationen können dem Fahrer in einem separaten Anzeigeelement oder in Kombination mit der Navigations-Einheit 1 angezeigt werden.The navigation device includes a stored in a memory list of electric charging stations for the electric vehicle. In addition, the electric vehicle has a range monitoring, which monitors the energy content of the electric energy storage and continuously calculates which distance the electric vehicle can still cover this energy content. This information may be provided to the driver in a separate display element or in combination with the navigation unit 1 are displayed.

Es wird fortlaufend sowohl die Entfernung zur nächsten Elektrotankstelle, als auch die aktuell verfügbare Reichweite des Elektrofahrzeuges überwacht. Beispielsweise kann die Entfernung zur nächstgelegen Tankstelle dem Fahrer über ein Symbol 4 innerhalb der Navigations-Einheit 1 dargestellt werden, beispielsweise mit abnehmender oder zunehmender Reichweiten-Anzeige 5. Wenn diese Reichweite nun nur noch knapp über der Entfernung zur nächstgelegenen, ermittelten oder abgespeicherten, Elektrotankstelle liegt, wird diese Elektrotankstelle automatisch als (Zwischen-)Ziel in der Navigations-Einheit 1 eingesetzt und das Elektrofahrzeug entsprechend der Eingabe zu der Tankstelle geleitet.It is continuously monitored both the distance to the nearest electric charging station, as well as the currently available range of the electric vehicle. For example, the distance to the nearest gas station to the driver via a symbol 4 within the navigation unit 1 represented, for example, with decreasing or increasing range indicator 5 , If this range is now only slightly above the distance to the nearest, determined or stored electric filling station, this electric charging station automatically becomes (intermediate) destination in the navigation unit 1 inserted and the electric vehicle passed according to the input to the gas station.

Zusätzlich dazu können reichweitenverlängernde Maßnahmen eingeleitet werden.In addition, range-extending measures may be initiated.
