Description
Sicherheit und Beförderungsleistung sind die wichtigsten Kriterien von Beförderungssystemen. Der KFZ-Verkehr schneidet dabei hinsichtlich seiner Unfallgefahr trotz aller Verbesserung in aktiver und passiver Sicherheit von Fahrzeugen schlecht ab, bei der Verkehrsleistung auf Grund der guten Nutzung des Verkehrsraumes im Vergleich zu anderen Verkehrsmitteln, insbesondere der Schiene, ist er relativ günstig und hat den Vorteil hoher individueller Disponierbarkeit.safety and transport services are the most important criteria of transport systems. The car traffic cuts in terms of its risk of accidents despite all the improvement in active and passive safety of vehicles from bad at the Traffic performance due to the good use of the traffic area compared to other means of transport, in particular rail, he is relatively cheap and has the advantage of high individual disposability.
Jedoch stehen hier die genannten Kriterien in unmittelbaren Widerspruch. Insbesondere auf zweispurigen Strassen widerspricht der nötige Sicherheitsabstand von Fahrzeugen bei derzeitigem Stand der Technik der bestmöglichen Auslastung des Verkehrsraumes: insbesondere beschränkt das Miteinander unterschiedlich schneller Fahrzeuge auf Landstraßen die Nutzung der Kapazitäten, weil gerade aus der Sicht eines PKW-Fahrers Anpassungsvorgänge, wie Überholen, vielfach nur sehr eingeschränkt oder unter Eingehen erheblichen Risikos möglich ist.however here are the mentioned criteria in direct contradiction. Especially on two-lane roads contradicts the necessary safety distance of vehicles in the current state of the art of the best possible Utilization of the traffic area: especially limited With each other different speed vehicles on highways the Use of capacities, because, especially from the point of view of a car driver, adjustment processes, such as overtaking, often only very limited or taking substantial risk is possible.
Es ist daher Aufgabe vorliegender Erfindung, solche Überholvorgänge sicher zu machen bzw. in unübersichtlichen Situationen überhaupt erst ohne Risiko zu ermöglichen und, weiter gehend, den Strassenverkehr hinsichtlich Sicherheit und Nutzung des Verkehrsraumes zu optimieren.It is therefore an object of the present invention, such overtaking safe to make or in confusing Situations at all first without risk and, going further, the road traffic in terms of safety and optimize usage of the traffic area.
Dies wird erfindungsgemäß dadurch erreicht, dass die Positionen und Bewegung anderer Verkehrsteilnehmer durch Satellitenüberwachung analysiert und dem einzelnen Fahrzeuglenker am Bildschirm dargestellt werden. Darüber hinaus ist es möglich, das Verfahren zur allgemeinen, automatischen Führung von Fahrzeugen zu erweitern.This is characterized according to the invention achieved that the positions and movement of other road users analyzed by satellite monitoring and the individual driver on the screen. About that It is also possible to expand the procedure for the general, automatic guidance of vehicles.
Satelliten-Navigationssysteme finden zunehmende Verbreitung. Dabei erfolgt bislang im individuellen Gerät eine Positionsanalyse, die durch die Ermittlung von Laufzeitunterschieden der Signle verschiedener Satelliten erzeugt wird.Satellite navigation systems find increasing distribution. This is done so far in the individual Device one Position analysis by determining transit time differences the signle of different satellites is generated.
Diese Position wird in Kartensysteme übertragen, um die aktuelle Straßenführung und den jeweils günstigsten Weg zu einem Ziel anzuzeigen.These Position is transferred to card systems, around the current road and the cheapest Way to indicate a goal.
Mit dem sog. TMC (Traffic Management Control)-System wird darüber hinaus versucht, durch Anzeige von Unfällen und Verkehrsstaus die Route zu optimieren.With The so-called TMC (Traffic Management Control) system is beyond tried by indicating accidents and traffic congestion to optimize the route.
Die Informationen hierzu kommen derzeit noch weitgehend von Personen als Staumeldungen via Mobilfunk, wie auch von Polizei und Straßenmeistereien und werden von unterschiedlichen Interessensgruppen, wie z. B. Funk- und Fernsehanstalten, insbesondere Regionalradiostationen und Betreibern der Navigationssystemen, verbreitet.The Information on this is currently still largely coming from people as traffic jam reports via mobile phone, as well as from police and road maintenance and are used by different interest groups, such as Eg radio and television stations, in particular regional radio stations and operators of Navigation systems, widespread.
In Vorbereitung sind dabei vielfach Systeme, die eine Rückmeldung von Navigationsgeräten und OBUs (On Board Units zur Mauterfassung) nutzen, aus denen die aktuelle Geschwindigkeit von Fahrzeugen, ihre Fahrtrichtung und ihre aktuelle Position ermittelt werden kann, um daraus die Verkehrssituation in einzelnen Straßenbereichen zu ermitteln und daraus aktuelle und sich entwickelnde Staus zu analysieren und die Routenwahl damit zu optimieren.In In many cases, preparation is provided by systems that provide feedback of navigation devices and OBUs (on - board units for toll collection), from which the current speed of vehicles, their direction of travel and their current position can be determined to determine the traffic situation in individual street areas to determine and from this current and developing congestion analyze and optimize the route selection.
Gegenstand der Erfindung ist es daher, die Auswertung so gewonnener Daten nicht nur zur allgemeinen Verkehrsanalyse zu verwenden, sondern die Positionen der Verkehrsteilnehmer für jeden Fahrer so aufzubereiten und anzuzeigen, dass er durch Anpassung seiner Geschwindigkeit und Nutzung möglichen Spielraumes für Überholmanöver bestmöglich und energiesparend vorankommt.object Therefore, the invention is not the evaluation of data thus obtained to use only for general traffic analysis, but the positions the road user for to prepare each driver and indicate that he is through adaptation its speed and use of possible scope for overtaking maneuvers and best possible energy saving progresses.
Dies setzt naturgemäß voraus, dass jeder Verkehrsteilnehmer ein zur Rückmeldung seiner Position geeignetes Gerät aktiviert, jedoch ist derartiges, wie für Lkws bereits Pflicht, auch für Pkws absehbar.This naturally presupposes that every road user is suitable for the feedback of his position Device activated, however, such is as for Trucks already mandatory, even for Cars foreseeable.
Zudem gibt es Systeme, sog. Blindfahrer z. B. durch Mautbrücken zu identifizieren. Daraus könnten ebensolche Warnmeldungen generiert werden, wie heute bei "Geisterfahrern". Erfindungsgemäß ist jedoch ihre Anzeige im Gerät, etwa durch einen Warnbalken neben der angezeigten Fahrbahn in jener Zone, die ein nicht angemeldetes Fahrzeug zum aktuellen Zeitpunkt (zwischen einer Meldung und der Folgendenden bzw. voraus projiziert) durchlaufen kann.moreover There are systems, so-called. Blind driver z. B. by toll bridges identify. Out of it could just as warning messages are generated, as today in "ghost drivers". However, according to the invention her ad in the device, for example, by a warning bar next to the indicated roadway in that Zone, which is an unregistered vehicle at the current time (projected between a message and the following or ahead) can go through.
Weiter ist es möglich, die Erfassungsgeräte so zu erweitern, dass umliegende und insbesondere auf der Gegenfahrbahn passierende Fahrzeuge durch die zum Einparken bereits vielfach integrierten und ggf. empfindlicher einrichtbaren PDC (Parc Distance Control)-Systeme detektiert werden. Sie können dann mit den Informationen, die per Rückmeldung aus dem Satellitensystem kommen, abgeglichen werden, um daraus ggf. wiederum Warnmeldungen an in diesen Verkehrsabschnitt einlaufende Fahrzeuge zu übermitteln, die dann wesentlich genauer sind.Further Is it possible, the detection devices like that to expand that surrounding and especially on the opposite lane passing vehicles by the already integrated for parking many times and possibly more sensitive PDC (Parc Distance Control) systems be detected. You can then with the information provided by feedback from the satellite system come, be reconciled, in turn, if necessary, turn warning messages to transmit vehicles entering this traffic section, which are much more accurate then.
Zur Anzeige und Darstellung der Verkehrssituation ist erfindungsgemäß vorgesehen, die Kraftfahrer eines Verkehrsabschnitts auf einem Kartenausschnitt in kleinen Pictogrammen darzustellen, die den Fahrzeugtyp anzeigen – um etwa bei Lastzügen – den erforderlichen Überholweg absehen zu können.to Display and presentation of the traffic situation is provided according to the invention, the motorists of a traffic section on a map cutting in small pictograms that show the vehicle type - for example for lorries - the required overtaking path to be able to refrain.
Dabei ist zur Darstellung der Fahrgeschwindigkeit der Verkehrsteilnehmer die Anzeige so vorgesehen, dass das Pictogramm die derzeitige Position anzeigt und voreilende Pfeile, transparent, gerastert oder ähnlich dargestellt, mit ihrer Spitze die zu erwartende Fahrstrecke innerhalb einer Zeiteinheit, z. B. 20 Sek., darstellen.there is to represent the driving speed of the road users the display is provided so that the pictogram indicates the current position and leading arrows, transparent, screened or similar, with its peak the expected route within a unit of time, z. B. 20 sec., Represent.
Kollisionsgefahren können hierbei z. B. durch rote Punkte oder Wolken, Überholmöglichkeiten durch grüne Wegepfeile angezeigt werden, die je nach Aktualität des zugehörigen Handlungsbedarfs schnell, langsam oder nicht blinken.risks of collision can hereby z. B. by red dots or clouds, overtaking by green way arrows which, depending on the topicality of the associated need for action, quickly, slowly or not blinking.
Vorzugsweise ist die Darstellung so angelegt, dass das eigene Fahrzeug in der Nähe des unteren Bildrandes gezeigt wird und die Darstellung vorausschauend angelegt ist (nach oben ist immer Fahrtrichtung), es ist aber auch denkbar, auf eine eingenordete Darstellung umschalten zu können und dabei die Verkehrssituation auf die Nahbereichskarte des Navigationssystems zu projizieren.Preferably the presentation is designed so that the own vehicle in the Near the lower edge of the picture is shown and the representation forward-looking is created (up is always the direction of travel), but it is also conceivable, to be able to switch to a eingedordete representation and thereby the traffic situation on the Nahbereichskarte of the navigation system to project.
Zudem ist es nahe liegend, das System auch so auszulegen, dass das zugehörige Gerät mit der Funktion üblicher Navigationsgeräte zur Routenwahl derartig kombiniert ist, dass die Einblendung einer vereinfachten Routenwahl-Darstellung (wie auf Navi-Systemen mit kleinem Bildschrirm) mit Pfeilen auf die Anzeige der Verkehrssituation erfolgt.moreover it is obvious that the system should also be designed so that the associated device with the usual function navigation devices for route selection is combined in such a way that the display of a simplified Route selection display (as on Navi systems with a small screen) with arrows on the display of the traffic situation.
Weiter ist es möglich, Gefahrenhinweise und Überholempfehlungen auch über eine – in Navigationsgeräten bereits implementierte – Sprachausgabe anzuzeigen.Further Is it possible, Hazard warnings and overtaking recommendations also over one - in navigation devices already implemented - to display speech output.
Es versteht sich, dass das Verfahren der Ermittlung von Verkehrssituationen und der Kombination mit optimaler Routenwahl als Vorstufe einer weitgehend automatisierten Verkehrsführung geeignet ist, insbesondere wenn die Genauigkeit der Satelliten-Positi onsmessung auch in Straßenschluchten durch Einsatz zunehmend verbesserter Verfahren, wie das Galileo-System und seiner Kombination mit dem GPSII-System erfolgt ist. Hierzu bietet sich ferner die Kombination mit weiteren Verkehrsinformations- und Telematik-Systemen an.It It is understood that the procedure of identifying traffic situations and the combination with optimal route choice as precursor of a largely automated traffic management is suitable, in particular if the accuracy of satellite positi onsmessung in street canyons through Use of increasingly improved processes, such as the Galileo system and its combination with the GPSII system is done. For this Furthermore, the combination with other traffic information and telematics systems.
