Abstract
Description
Die geographischen Daten für Navigationssysteme werden zentral erfaßt. Änderungen werden durch Updates in Abständen von mehr als sechs Monaten verteilt, so daß regelmäßig unvollständige Daten zu falschen oder nicht optimalen Routen führen.The geographic data for Navigation systems are recorded centrally. Changes are made by updates at intervals distributed over more than six months, so that regularly incomplete data lead to wrong or not optimal routes.
Alternativ werden Routen über eine Datenverbindung von einem zentralen Server angefordert, dort berechnet und dann die Streckeninformationen an das Navigationssystem übermittelt. Hier entsprechen die berechneten Routen dem aktuellen, zentralen Datenbestand, allerdings fallen erhebliche Kosten für die zentrale Berechung und die Übertragung der Routendaten an.alternative will routes over a data connection requested from a central server, there calculated and then transmitted the route information to the navigation system. Here the calculated routes correspond to the current, central one Data, but there are significant costs for the central Calculation and transfer of the Route data.
Das in Patentanspruch 1 beschriebene Navigationssystem ergänzt nicht im Kartenwerk vorhandene Strecken, sobald diese befahren werden.The in navigation system described in claim 1 does not supplement existing routes in the map, as soon as they are traveled.
Der Streckenverlauf wird in einem Navigationssystem anhand der kontinuierlich erfaßten Positionsdaten (Satellitennavigation, eventuell ergänzt durch zusätzliche Sensorik) ermittelt. Die so gewonnenen Positionsdaten werden gegen die bekannten Kartendaten abgeglichen um die aktuelle Position des Fahrzeugs im durch die Kartendaten erfaßten Straßennetz zu bestimmen.Of the Route is in a navigation system based on the continuous detected Position data (satellite navigation, possibly supplemented by additional Sensor). The position data obtained in this way will be counteracted the known map data adjusted to the current position of the Vehicle in the detected by the map data road network to determine.
Wenn in einem Navigationssystem nach Patentanspruch 1 keine Übereinstimmung zwischen Position des Fahrzeugs und im Kartenwerk vorhandenen Straßenverläufen festgestellt werden kann, dann werden die Positionsdaten des Streckenverlaufs kontinuierlich gespeichert, bis wieder eine Übereinstimmung mit den vorhandenen Kartendaten festgestellt werden kann. Um die vollständige Erfassung aller Positionsdaten, seit dem Verlassen des in dem Kartenwerk gespeicherten Straßennetzes zu sichern, müssen in einem Ringpuffer stets so viele Positionsdaten zwischengespeichert werden, daß alle Positionen von dem Punkt ab, an dem das im Kartenwerk erfaßte Straßennetz verlassen wurde, zu dem Zeitpunkt noch vorhanden sind, an dem das System erkennt, daß die aktuelle Position nicht mehr im Kartenwerk enthalten ist.If in a navigation system according to claim 1 no match detected between position of the vehicle and in the map existing roads can be, then the position data of the route continuously stored until again a match with the existing ones Map data can be found. To complete the capture of all position data since leaving the map stored in the map road network to secure always stored as many position data in a ring buffer be that all positions from the point at which the road network covered in the map work was abandoned the time at which the system recognizes that the current Position is no longer included in the map work.
Diese so gewonnenen Positionsdaten beschreiben dann den Verlauf eines bisher in den Kartendaten nicht erfaßten Streckenabschnitts. Anhand der beim Befahren ermittelten Geschwindigkeiten können die befahrenen Straßen klassifiziert werden. Zusatzinformationen (z.B. Geschwindigkeitsbegrenzungen, Gefahrenstellen, Überwachungsvorrichtungen) können von den Benutzern bei der Erfassung ergänzt werden.These Position data obtained in this way then describe the course of a previously not included in the map data track section. Based on when driving determined speeds can be classified the roads used become. Additional information (eg speed limits, Danger spots, monitoring devices) can be supplemented by the users when capturing.
Durch statistische Verfahren beim Abgleich vieler auf diese Weise gewonnenen Daten können ungültige Daten (Querfeldeinfahrten) erkannt werden und sowohl die Präzision der Streckenerfassung als auch die Zuverlässigkeit der Klassifikation verbessert werden.By Statistical procedures in the comparison of many obtained in this way Data may be invalid data (Cross country) and both the precision of the Range detection as well as the reliability of the classification be improved.
Es ist also möglich, nach mehrfachem Befahren eines in den Kartendaten nicht enthaltenen Streckenverlaufs und Abgleich der hierbei gewonnenen Daten, die Kartendaten mit einer ausreichend genauen Beschreibung des neu erfaßten Streckenverlaufs zu ergänzen.It is possible, after repeated driving on one not contained in the map data Route and comparison of the data obtained, the Map data with a sufficiently accurate description of the newly recorded route to complete.
Dieser Vorgang läßt sich dadurch beschleunigen und auf größere Gebiete ausweiten, daß mehrere Navigationssysteme die erfaßten Daten miteinander direkt oder über eine Zentrale austauschen.This Process can be thereby speeding up and to larger areas expand that several Navigation systems that captured Data with each other directly or via replace a central office.
Über ein Netzwerk werden die neu ermittelten Strecken zwischen den Datenbeständen der teilnehmenden Navigationssysteme verteilt und abgeglichen. Wenn genügend Streckendaten vorliegen, werden daraus Ergänzungen der Kartendaten erzeugt und diese wiederum über das Netzwerk verteilt. Auf diese Weise werden die geographischen Datenbestände der beteiligten Navigationssysteme kontinuierlich aktuell gehalten. In den Navigationssystemen gespeicherte, neu erfaßte Streckenverläufe werden dann wiederum mit den Aktualisierungen des Kartenmaterials verglichen und bei Übereinstimmung gelöscht.About one Network will be the newly identified routes between the databases of Distributed and synchronized participating navigation systems. If enough Route data are available, supplements of the map data are generated and these in turn over distributed the network. In this way, the geographic datasets of the participating navigation systems are kept up to date. In the navigation systems stored, newly detected routes are then again compared with the updates of the map material and at agreement deleted.
Für Verteilung und Abgleich der Daten kommen verschiedene Netzwerke in Betracht:For distribution and matching the data, different networks are possible:
Bei portablen Navigationssystemen ist ein regelmäßiger Abgleichvorgang über ein öffentliches Netzwerk (Internet) mit zentralen Servern möglich. Dort ist dann auch eine redaktionelle Nachbearbeitung entweder über eine zentrale Redaktion oder durch die Benutzer (Wild) möglich.at portable navigation systems is a regular reconciliation process over a public network (Internet) with central servers possible. There is also one there Editorial editing either via a central editorial office or by the users (game) possible.
Bei fest in den Fahrzeugen eingebauten Systemen ist der Zugang zu öffentlichen Netzwerken naturgemäß beschränkt (WLAN in der heimatlichen Garage) bzw. teuer (GSM/UMTS). Es ist auch denkbar, über Ad-hoc-Netzwerke von Fahrzeug zu Fahrzeug den Datenabgleich vorzunehmen. In diesem Fall würde der Datenabgleich in den Navigationssystemen vorgenommen. Möglich ist auch eine Kombination aus serverbasiertem und Ad-hoc Abgleich.at Fixed systems installed in vehicles is access to public Naturally limited networks (WLAN in the home garage) or expensive (GSM / UMTS). It is also conceivable through ad hoc networks of vehicle to reconcile to vehicle. In this case, the Data adjustment made in the navigation systems. Is possible also a combination of server-based and ad-hoc reconciliation.
