Abstract
Description
Die Erfindung betrifft ein Verfahren zur Aktualisierung von digitalen Straßenkarten eines Offboard-Navigationssystems.The invention relates to a method for updating digital road maps of an offboard navigation system.
Navigationssysteme für Karftfahrzeuge gewinnen zunehmend an Bedeutung. Viele Navigationssysteme arbeiten auf der Basis von digitalen Straßenkarten, die zur Verkehrslenkung und Zielführung der Fahrzeuge eingesetzt werden. Eine effektive Verkehrslenkung und Zielführung setzt allerdings voraus, daß die verwendete digitale Straßenkarte möglichst aktuell ist. Aufgrund immer neu entstehender Straßen, z. B. in Gewerbegebieten, wäre eine ständige Aktualisierung der elektronischen Straßenkarten wünschenswert, was jedoch unter praktischen Gesichtspunkten und Kostengründen kaum praktikabel erscheint.Navigation systems for car vehicles are becoming increasingly important. Many navigation systems work based on digital road maps that are used to control traffic and guidance of the Vehicles are used. Effective traffic control and guidance assumes, however, that the used digital road map preferably is current. Due to constantly emerging roads, e.g. B. in commercial areas a constant Updating the electronic road maps is desirable, but what under practical aspects and cost reasons appear hardly practical.
Gemäß einem geplanten Offboard-Navigationsdienst ist es möglich, Fahrzeugen ohne Navigationssystem, aber mit Telefon oder Monitor, auf Anfrage online Kartenausschnitte in einen bestimmten Korridor zwischen Start und Ziel mit einer berechneten Strecke von einem Verkehrsrechner des Offboard-Navigationssystems in das Fahrzeug zu laden. Die berechnete Strecke (Zielführung) und das Einhalten des Korridors wird von einem im Fahrzeug befindlichen GPS-System (Global Positioning System zur satellitenunterstützen Positionsbestimmung) überwacht. Wenn das Fahrzeug innerhalb des vom Offboard-Navigationssystem übermittelten Korridors (Kartenausschnittes) eine auf der digitalen Straßenkarte des Offboard-Navigationssystems noch nicht vorhanden Straße befährt, z. B. weil diese neu gebaut wurde, dann wird vom Offboard-Navigationssystem davon ausgegangen, daß sich das Fahrzeug nicht mehr im Kartensegment befindet und es wird eine neue Route berechnet und zum Fahrzeug übertragen. Dies verursacht sowohl unnötige Neuberechnungen als auch Fehlermeldungen.According to a planned offboard navigation service Is it possible, Vehicles without navigation system, but with telephone or monitor, Map sections in a specific corridor can be requested online between start and finish with a calculated distance of one Traffic computer of the offboard navigation system in the vehicle to load. The calculated route (route guidance) and compliance with the Corridor is controlled by a GPS system (Global Positioning system for satellite-assisted position determination) monitored. If the vehicle is within the range communicated by the offboard navigation system Corridor (section of map) one on the digital street map the offboard navigation system does not yet exist on the road, e.g. B. because this was built by the offboard navigation system assumed that the vehicle is no longer in the map segment and it becomes one calculated new route and transferred to the vehicle. This is causing both unnecessary Recalculations as well as error messages.

Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Aktualisieren von digitalen Straßenkarten eines Offboard-Navigationssystems anzugeben, welches eine rasche und kostengünstige Aktualisierung ermöglicht.The invention is based on the object Method for updating digital road maps of an offboard navigation system indicate which enables a quick and inexpensive update.
Diese Aufgabe wird im Wesentlichen gelöst durch das Verfahren gemäß Patentanspruch 1, wobei durch ein geeignet ausgerüstetes Fahrzeug die momentanen Ortspositionen des Fahrzeugs ermittelt und gespeichert werden, die momentanen Ortspositionen mit den in den digitalen Straßenkarten vorhandenen Straßen verglichen werden, bei Abweichungen der momentanen Ortsposition von den in den digitalen Straßenkarten vorhandenen Straßen um einen vorgegebenen Mindestbetrag diese abweichenden Ortspositionen als "unbekannte Straße" klassifiziert werden, ein Verkehrsrechner des Offboard-Navigationssystems die in den abweichenden Ortspositionen enthaltenen Informationen auswertet und die digitale Straßenkarte um die "unbekannte Straße" als weitere Straße entsprechend aktualisiert.This task essentially solved by the method according to claim 1, the momentary by a suitably equipped vehicle Locations of the vehicle are determined and stored, the current locations with those in the digital road maps existing roads be compared in the event of deviations in the current position of those in the digital road maps existing roads these deviating location positions by a predetermined minimum amount as "unknown Street "can be classified, a traffic computer of the offboard navigation system in the deviating Evaluates information contained in the location and digital road map to the "unknown Street "as another street accordingly updated.
Gemäß der vorliegenden Erfindung ist somit vorgesehen, daß die im Offboard-Navigationssystem vorhandene statische digitale Straßenkarte dynamisch ergänzt wird. Bei weiteren Abfragen auf dem die neue Straße enthaltenden Gebiet wird dann bereits der um die neue Straßen aktualisierte Straßenkartenabschnitt übertragen.According to the present invention it is thus provided that the Static digital road map available in the offboard navigation system added dynamically becomes. With further queries on the one containing the new street The road map section updated with the new roads is then already transferred to the area.
Weiterhin von Vorteil ist, daß dann, wenn eine neue CD der digitalen Straßenkarte erstellt wird, die Informationen über die neuen Straßen bei ausreichender Genauigkeit direkt mit einfließen und dann ab sofort auch statisch verfügbar sind. Bislang hat man sich solche Informationen beschafft, indem auf den neuen Straßen entlanggefahren wurde und die Position der neuen Straßen "von Hand" gemessen wurden.Another advantage is that when a new CD of the digital road map is created, the information about the new streets if there is sufficient accuracy, flow directly in and then immediately statically available are. So far, such information has been obtained by on the new streets was driven along and the position of the new roads were measured "by hand".
In bevorzugter Weiterbildung der Erfindung ist vorgesehen, daß die Aktualisierung der digitalen Straßenkarte um die unbekannte Straße erst erfolgt, wenn mehrere geeignet ausgerüstete Fahrzeuge die unbekannte Straße durchfahren haben oder ggf. auch ein solches Fahrzeug die unbekannte Straße mehrmals durchfahren hat. Zum einen wird hierdurch die Genauigkeit der Positionsdaten der neuen Straße erhöht, zum anderen können dann mögliche Fehlinterpretationen mit hoher Wahrscheinlichkeit vermieden werden.In a preferred development of the invention, it is provided that the digital road map is not updated around the unknown road until several suitably equipped vehicles have passed through the unknown road or, if appropriate, such a vehicle has passed through the unknown road several times. For one thing, this will the accuracy of the position data of the new road is increased, on the other hand possible misinterpretations can then be avoided with a high probability
In bevorzugter Weiterbildung der Erfindung ist vorgesehen, daß das Fahrzeug mit einer Zielführungseinheit ausgerüstet ist, der vom Offboard-Navigationssystem Fahrtroutendaten gegebenenfalls einschließlich Straßenkartendaten übermittelt werden, daß die Abweichungen der momentanen Ortspositionen von den übermittelten Fahrtroutendaten bzw. Straßenkartendaten festgestellt werden und die abweichenden Ortspositionen zum Offboard-Navigationssystem übertragen werden. Insbesondere kann die Übertragung von der Zielführungseinheit zum Offboard-Navigationssystem mittels des Floating Car Data-Systems (FCD) erfolgen. Die Feststellung einer "unbekannten Straße" erfolgt hierbei also im Fahrzeug. Zur Datenübertragung wird der in der Telematik bereits eingeführte Dienst FCD genutzt, der Fahrzeugdaten und Positionen an den Verkehrsrechner des Offboard-Navigationssystems übermittelt, sobald ein bestimmtes "Event" eintritt. Ein solches Event, z. B. "Stehen auf der Autobahn", ist jeweils mit einer eindeutigen Identifikationsnummer versehen, damit es auf dem Verkehrsrechner richtig zugeordnet werden kann. Im Falle eines Events wird die Position anhand einer sogenannten Perlenkette (z. B. letzte fünf Positionen aller 1000 Meter) genau übermittelt (nähere Informationen zur Perlenkette ergeben sich aus den GATS Spezifikationen des Serviceproviders Vodafane Passo).In a preferred further education of Invention is provided that Vehicle with a route guidance unit equipped is the route data from the offboard navigation system, if applicable including Road map data transmitted be that the Deviations of the current location positions from the transmitted Route data or road map data are determined and the deviating location positions are transmitted to the offboard navigation system become. In particular, the transfer from the route guidance unit to the offboard navigation system using the floating car data system (FCD). The determination of an "unknown road" is thus carried out in the vehicle. to data transfer the FCD service, which has already been introduced in telematics, is used Vehicle data and positions are transmitted to the traffic computer of the offboard navigation system, as soon as a certain "event" occurs. Such one Event, e.g. B. "Standing on the highway" is with each provided with a unique identification number so that it can be found on the Traffic calculator can be assigned correctly. In the event of an event the position is determined using a so-called pearl necklace (e.g. last five positions every 1000 meters) (for more Information about the pearl necklace can be found in the GATS specifications of the service provider Vodafane Passo).
Weiterhin bevorzugt ist es, wenn den abweichenden Ortspositionen eine eigene Identifikation zugeordnet wird, die zusammen mit diesen zum Offboard-Navigationssystem übertragen wird.It is further preferred if a separate identification is assigned to the deviating location positions which is transmitted together with these to the offboard navigation system becomes.
