Description

Die Erfindung bezieht sich auf ein Verfahren sowie auf eine Vorrichtung zur Selektion von Verkehrsinformation für ein Kraftfahrzeug. Ein derartiges Verfahren bzw. eine derartige Vorrichtung sind bereits allgemein bekannt. Nach herkömmlichem Stand der Technik kann der Fahrer eines Kraftfahrzeugs vor Beginn einer Fahrt einem im Kraftfahrzeug installierten Telematik-Endgerät mitteilen, für welchen geographischen Bereich er Verkehrsinformation wünscht. Hierzu muß entsprechende Information in das Telematik-Endgerät manuell eingegeben werden, etwa dahingehend, daß sich der Fahrer zukünftig nur innerhalb einer Stadt zu bewegen wünscht oder beabsichtigt, zum Beispiel auf einer Überlandstrecke oder Autobahn ein entfernteres Ziel anzusteuern. Im zuerst genannten Fall wird ihm dann nur Verkehrsinformation angezeigt bzw. mitgeteilt, die für einen kreisförmigen Bereich mit einem vorbestimmten Radius um das Kraftfahrzeug herum relevant ist. Dabei kann der Fahrer auch die Größe des Radius selbst festlegen. Demgegenüber wird im zuletzt genannten Fall dem Fahrer nur Verkehrsinformation übermittelt, die für einen vorbestimmten Bereich um das Kraftfahrzeug herum und für denjenigen Bereich gilt, in welchem sich das Kraftfahrzeug in Richtung auf das Ziel bewegt. Im zweiten Fall ist der Bereich, für den relevante Verkehrsinformation erhalten wird, quasi schlüssellochförmig ausgebildet. Auch hier können Radien und Entfernungen vom Fahrer vor Antritt der Fahrt frei gewählt oder vom System vorgegeben werden.The invention relates to a method and an apparatus for the selection of traffic information for a motor vehicle. Such a thing Methods and such a device are already generally known. According to the conventional art, the driver can Motor vehicle before the start of a trip installed in a motor vehicle Telematics terminal announce for which geographic area it Traffic information wishes. For this purpose, appropriate information in the telematics terminal can be entered manually, for example in that that the driver will only move within one city in the future wishes or intends, for example on an overland route or Highway to a more distant destination. In the first case he will then only be shown or informed of traffic information for a circular area with a predetermined radius around it Motor vehicle around is relevant. The driver can also change the size of the radius itself. In contrast, in the latter case to the driver only traffic information transmitted for a predetermined Area around the motor vehicle and for that area applies in which the motor vehicle moves in the direction of the target. In the second case, the area for which relevant traffic information is is obtained, quasi keyhole-shaped. Here too Radii and distances freely selected by the driver before starting the journey or specified by the system.

Nachteilig bei dem bekannten Verfahren ist, daß der Fahrer vor Fahrtantritt die jeweiligen Bereiche, für die er Verkehrsinformation wünscht, selbst auswählen muß. Hierzu müssen geeignete Filterparameter in das Telematik-Endgerät eingegeben werden, durch die aus einer großen Menge von Verkehrsinformation nur diejenige herausgefiltert wird, die sich auf den vom Fahrer ausgewählten Bereich bezieht. Bei ständig zunehmender Anzahl von elektronischen Einrichtungen in einem Kraftfahrzeug ist die zusätzliche manuelle Eingabe von Filterparametern zur Auswahl von Verkehrsinformation jedoch nicht wünschenswert, da sie eine zusätzliche Belastung des Fahrers darstellt und ihn unter Umständen ablenken könnte, sofern er eine Einstellung während der Fahrt vornimmt. A disadvantage of the known method is that the driver starts driving the respective areas for which he wants traffic information, must choose itself. For this purpose, suitable filter parameters must be entered in the Telematics terminal can be entered from a large amount of traffic information is only filtered out to those who are on relates to the area selected by the driver. With ever increasing Number of electronic devices in a motor vehicle is the additional manual input of filter parameters to select traffic information however not desirable as it is an additional burden represents the driver and could possibly distract him, if he makes a setting while driving.

Aus der EP 0 789 343 A1 ist bereits ein Verfahren zur Selektion von empfangener oder zu sendender Verkehrsinformation in einem Fahrzeug bekannt, wobei die Selektion in Abhängigkeit vom Typ der Straße, die das Fahrzeug momentan befährt, erfolgt. Hier wird fahrzeugseitig eine abschnittsweise Bestimmung des geometrischen Fahrtverlaufs durchgeführt, wobei die Angaben zum jeweiligen Abschnitt des geometrischen Fahrtverlaufs mindestens die relative Lage des Anfangs- und Endpunkts dieses Abschnitts zueinander umfassen, und dieser Abschnitt des Fahrtverlaufs mit charakteristischen geometrischen Kenngrößen von Straßentypen verglichen wird, woraus der aktuell befahrene Straßentyp bestimmt und als Selektionskriterium benutzt wird. Kennzeichnend dabei ist es allerdings, daß keine Zeitbetrachtungen erforderlich sind, sondern daß man allein mit geometrischen Angaben über den Fahrtverlauf auskommt.EP 0 789 343 A1 already describes a method for selecting received ones or traffic information to be transmitted is known in a vehicle, the selection depending on the type of street that the Vehicle is currently being driven. Here on the vehicle side is a section Determination of the geometric course of the journey carried out, the details of the respective section of the geometric At least the relative position of the start and end point this section to each other, and this section of the journey with characteristic geometric parameters of road types is compared, from which the currently used road type determines and is used as a selection criterion. It is characteristic, however, that no time considerations are required, but that one get by with geometric information about the course of the journey alone.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art so weiterzubilden, daß eine einfachere und weniger zeitaufwendige, dennoch aber hochgenaue Auswahl von Bereichen, für die Verkehrsinformation gewünscht wird, möglich ist.The invention has for its object a method and an apparatus of the type mentioned in such a way that a simpler and less time-consuming, yet highly accurate selection of areas, for which traffic information is desired is possible.

Eine verfahrensseitige Lösung der gestellten Aufgabe ist im Anspruch 1 angegeben. Dagegen findet sich eine vorrichtungsseitige Lösung der gestellten Aufgabe im Anspruch 10. Vorteilhafte Ausgestaltungen der Erfindung sind den jeweils nachgeordneten Unteransprüchen zu entnehmen.A procedural solution to the problem is in claim 1 specified. In contrast, there is a device-side solution to the posed Object in claim 10. Advantageous embodiments of the invention can be found in the subordinate claims.

In Übereinstimmung mit der Erfindung wird bei einem Verfahren zur Selektion von Verkehrsinformation für ein Kraftfahrzeug die Selektion automatisch und in Abhängigkeit eines zeitabhängigen Bewegungsprofils des Kraftfahrzeugs durchgeführt. Der Fahrer braucht sich somit nach Start seines Kraftfahrzeugs bzw. Einschalten seines Telematik-Endgeräts überhaupt nicht mehr um die Auswahl der jeweiligen Bereiche, für die er Verkehrsinformation zu erhalten wünscht, zu kümmern, sondern kann sich voll auf den Straßenverkehr konzentrieren, was die Fahrt im Kraftfahrzeug wesentlich vereinfacht und sicherer macht. In accordance with the invention, a method for selection selection of traffic information for a motor vehicle automatically and depending on a time-dependent movement profile of the Motor vehicle performed. The driver therefore needs himself after the start his motor vehicle or switching on his telematics terminal at all no longer about the selection of the respective areas for which he traffic information desires to take care of but can care fully focus on the road, what driving in the car significantly simplified and more secure.

Das Bewegungsprofil des Kraftfahrzeugs kann dazu auf unterschiedliche Weise ermittelt werden, beispielsweise durch am Kraftfahrzeug vorhandene Beschleunigungsaufnehmer und Richtungssensoren einerseits oder andererseits durch in Verbindung mit Zeitmeßgeräten arbeitende Funk-Positionsgeber, etwa GPS-Empfänger, und dergleichen. Zusammen mit dem Bewegungsprofil des Kraftfahrzeugs dient dann dessen aktuelle Position zur Auswahl der relevanten Verkehrsinformation, also zur Auswahl desjenigen Bereiches, für den Verkehrsinformation seitens des Fahrers gewünscht wird.The movement profile of the motor vehicle can be different Be determined, for example by existing on the motor vehicle Accelerometers and direction sensors on the one hand or on the other hand by radio position transmitters working in conjunction with timing devices, such as GPS receivers, and the like. Along with the current position then serves the movement profile of the motor vehicle for the selection of the relevant traffic information, i.e. for selection of the area for which the driver receives traffic information it is asked for.

Die Selektion der Verkehrsinformation kann beispielsweise unmittelbar im Telematik-Endgerät des Kraftfahrzeugs erfolgen, zum Beispiel dann, wenn Verkehrsinformation für sehr große geographische Gebiete von öffentlichen Sendern abgestrahlt und von der Masse der Verkehrsteilnehmer empfangen wird. In diesem Fall wird die für die sehr großen geographischen Gebiete geltende Verkehrsinformation in einem zum Telematik-Endgerät des Kraftfahrzeugs gehörenden Verkehrsinformationsspeicher zwischengespeichert und mit jedem Sendezyklus der öffentlichen Sender aktualisiert bzw. auf den neuesten Stand gebracht. Aus dieser so zwischengespeicherten Verkehrsinformation wird dann die für den Fahrer relevante Verkehrsinformation in Abhängigkeit des Bewegungsprofils des Kraftfahrzeugs herausgefiltert bzw. selektiert, und zwar in Abhängigkeit von Filterparametern, die aufgrund des Bewegungsprofils des Kraftfahrzeugs generiert werden.The selection of the traffic information can be immediate, for example in the telematics terminal of the motor vehicle, for example then when traffic information for very large geographic areas from public Broadcasters emitted and by the mass of road users Will be received. In this case, the very large geographical Areas relevant traffic information in a to the telematics terminal traffic information memory belonging to the motor vehicle cached and with each broadcast cycle of the public broadcaster updated or brought up to date. From this so cached Traffic information is then relevant for the driver Traffic information depending on the movement profile of the Motor vehicle filtered out or selected, depending on of filter parameters based on the motion profile of the motor vehicle to be generated.

Wird dagegen auf Anforderung eines einzelnen Verkehrsteilnehmers Verkehrsinformation für einen gewünschten Bereich von einem Service-Provider übermittelt, so könnte die Selektion von Verkehrsinformation auch beim Service-Provider ausgeführt werden, so daß an den anfragenden Verkehrsteilnehmer nur noch weniger Information übertragen zu werden braucht, was dessen Benutzerkosten senkt und den im Telematik-Endgerät erforderlichen Speicherplatzbedarf verringert. Hierzu muß allerdings zuvor der anfragende Verkehrsteilnehmer seine aktuelle Position und die aus dem Bewegungsprofil seines Kraftfahrzeugs abgeleiteten Filterparameter zum Service-Provider übertragen.On the other hand, traffic information becomes available at the request of an individual road user for a desired area from a service provider transmitted, so could the selection of traffic information be carried out at the service provider, so that to the requesting road user only less information to be transmitted needs what lowers its user costs and that in the telematics terminal required space requirements reduced. To do this, however before the requesting road user his current position and the filter parameters derived from the movement profile of his motor vehicle transferred to the service provider.

Nach einer Ausgestaltung der Erfindung kann die Selektion der Verkehrsinformation zum Beispiel in Abhängigkeit der Geschwindigkeit des Kraftfahrzeugs durchgeführt werden. Bewegt sich das Kraftfahrzeug bei relativ niedriger Geschwindigkeit und unterhalb eines vorgegebenen Geschwindigkeitswertes, so werden die Filterparameter automatisch so gewählt, daß die Verkehrsinformation nur für einen kreisförmigen Bereich um das Kraftfahrzeug herum an den Fahrer übermittelt wird. Liegt dagegen die Geschwindigkeit des Kraftfahrzeugs oberhalb des vorgegebenen Geschwindigkeitswertes, so erfolgt die Selektion so, daß den Fahrer nur noch Verkehrsinformation für einen relativ schmalen und sich in Fahrtrichtung des Fahrzeugs erstreckenden Bereichs erreicht.According to an embodiment of the invention, the selection of the traffic information for example depending on the speed of the motor vehicle be performed. The motor vehicle is moving at relative low speed and below a predetermined speed value, the filter parameters are automatically selected so that the traffic information only for a circular area around the Motor vehicle is transmitted around to the driver. However, is the Speed of the motor vehicle above the predetermined speed value, so the selection is made so that the driver only Traffic information for a relatively narrow and moving in the direction of travel range of the vehicle is reached.

Nach einer Weiterbildung der Erfindung kann die Selektion zusätzlich in Abhängigkeit von Änderungen der Fahrtrichtung des Kraftfahrzeugs erfolgen. Fährt das Kraftfahrzeug bei relativ kleiner mittlerer Geschwindigkeit und treten gleichzeitig relativ hohe mittlere Richtungsänderungen der Fahrtrichtung auf, so wird angenommen, daß sich das Kraftfahrzeug innerhalb eines Stadtgebiets aufhält. In diesem Fall wird der Bereich, für den Verkehrsinformation an den Fahrer übermittelt werden soll, kreisförmig um das Kraftfahrzeug herumgelegt, und zwar mit relativ engem Radius. Bewegt sich dagegen das Kraftfahrzeug mit relativ hoher mittlerer Geschwindigkeit (oberhalb des vorgegebenen Geschwindigkeitswertes) und treten gleichzeitig relativ kleine mittlere Richtungsänderungen der Fahrtrichtung des Kraftfahrzeugs auf, so wird davon ausgegangen, daß sich das Kraftfahrzeug auf einer Schnellstraße oder Autobahn in Richtung zu einem entfernterem Ziel bewegt. In diesem Fall werden die Filterparameter so ausgewählt bzw. generiert, daß sich der für Verkehrsinformation relevante Bereich in Richtung der Fahrtroute zum Ziel erstreckt, wie bereits oben erwähnt.According to a further development of the invention, the selection can also be carried out in Depending on changes in the direction of travel of the motor vehicle. The motor vehicle drives at a relatively low average speed and occur at the same time relatively high mean changes in direction Direction of travel on, it is assumed that the motor vehicle is within of an urban area. In this case, the area for the traffic information is to be transmitted to the driver, circular placed around the motor vehicle, with a relatively narrow radius. In contrast, the motor vehicle is moving at a relatively high average speed (above the specified speed value) and At the same time there are relatively small changes in the direction of travel of the motor vehicle, it is assumed that the Motor vehicle on an expressway or freeway towards one distant target moves. In this case, the filter parameters selected or generated so that the relevant for traffic information Area extends in the direction of the route to the destination, as already mentioned above.

Beim Start des Kraftfahrzeugs liegt im allgemeinen noch kein Bewegungprofil des Kraftfahrzeugs vor, so daß dann Verkehrsinformationen automatisch aus einem kreisförmigen Gebiet mit vorbestimmten Radius um das Kraftfahrzeug herum selektiert wird, wobei in diesem Fall der Radius relativ groß ist. Nach Aufnahme des Bewegungsprofils des Kraftfahrzeugs kann dann der Radius entsprechend verkleinert werden, wenn das Kraftfahrzeug im Stadtbereich verbleibt, oder es wird der relevante Bereich für Verkehrsinformation schlauchförmig in Richtung auf ein entfernteres Ziel ausgedehnt, falls sich das Bewegungsprofil des Kraftfahrzeugs entsprechend ändert.When the motor vehicle is started, there is generally no movement profile of the motor vehicle in front, so that traffic information is then automatic from a circular area with a predetermined radius the motor vehicle is selected around, in which case the radius is relatively large. After recording the movement profile of the motor vehicle the radius can then be reduced accordingly if the motor vehicle remains in the city area, or it becomes the relevant area for Traffic information tubular to a more distant destination extended if the movement profile of the motor vehicle changes accordingly changes.

Vorzugsweise werden Geschwindigkeiten sowie Fahrtrichtungsänderungen des Kraftfahrzeugs jeweils in vorbestimmten Zeitabschnitten ermittelt, um die Verkehrsinformationsselektion möglichst aktuell zu halten. Bezogen auf diese Zeitabschnitte werden somit jeweils neue Filterparameter aufgrund der in den genannten Zeitabschnitten jeweils erhaltenen mittleren Geschwindigkeits- und Richtungswerte generiert, was für eine gewisse Eigendynamik des Selektionsverfahrens sorgt. Einerseits kann aufgrund der für die jeweiligen Zeitabschnitte geltenden Filterparameter ständig aktuelle und aufden Ort des Kraftfahrzeugs bezogene Verkehrsinformation herausgefiltert bzw. selektiert werden, während andererseits die im Verkehrsinformationsspeicher gespeicherte Verkehrsinformation immer auf den neuesten Stand gebracht und entsprechend überschrieben werden kann.Speeds and changes in the direction of travel are preferred of the motor vehicle in each case determined in predetermined time segments, to keep the traffic information selection as up to date as possible. In relation to these time periods, new filter parameters are thus created based on the respectively received in the periods mentioned generated average speed and direction values, what a certain dynamics of the selection process. On the one hand can based on the filter parameters applicable for the respective time periods constantly updated traffic information related to the location of the motor vehicle filtered out or selected while on the other hand the traffic information stored in the traffic information memory always updated and overwritten accordingly can be.

Eine Vorrichtung zur Selektion von Verkehrsinformation für ein Kraftfahrzeug enthält eine Filtereinrichtung, die in Abhängigkeit von Filterparametern Verkehrsinformation nur für einen vorgegebenen geographischen Bereich hindurchläßt; eine Filterparameter-Erzeugungseinrichtung zur automatischen Erzeugung der Filterparameter in Abhängigkeit eines zeitabhängigen Bewegungsprofils des Kraftfahrzeugs; und eine Ausgabeeinrichtung zur Ausgabe der hindurchgelassenen Verkehrsinformation.A device for the selection of traffic information for a motor vehicle contains a filter device that depends on filter parameters Traffic information only for a given geographical area lets through; a filter parameter generating device for automatic Generation of the filter parameters depending on a time-dependent Motion profile of the motor vehicle; and an output device for output of the traffic information passed through.

Eine derartige Vorrichtung kann sich zum Beispiel in einem Telematik-Endgerät befinden, das in einem Kraftfahrzeug installiert ist. Im Falle des Telematik-Endgeräts würde man dann die Filterparameter-Erzeugungseinrichtung eingangsseitig mit einer Einrichtung zur Lieferung des Bewegungsprofils des Kraftfahrzeugs verbinden, wobei diese Einrichtung zum Beispiel Geschwindigkeit und Fahrtrichtung, ggf. auch daraus abgeleitete Mittelwerte, zur Filterparameter-Erzeugungseinrichtung überträgt. Die Ausgabeeinrichtung wäre dann eine optische oder akustische Anzeigeeinrichtung zur Übermittlung der selektierten Verkehrsinformation an den Fahrer des Kraftfahrzeugs. Gleichzeitig könnte die Filtereinrichtung mit einer eingangsseitigen Speichereinrichtung zur Speicherung von empfangener Verkehrsinformation verbunden sein.Such a device can be found, for example, in a telematics terminal are located, which is installed in a motor vehicle. In the case of Telematics terminal would then be the filter parameter generator on the input side with a device for supplying the movement profile connect the motor vehicle, this device for Example speed and direction of travel, if necessary also derived from it Average values, transmitted to the filter parameter generating device. The The output device would then be an optical or acoustic display device to transmit the selected traffic information to the Driver of the motor vehicle. At the same time, the filter device could an input-side storage device for storing received Traffic information.

Würde man dagegen die Vorrichtung senderseitig anordnen, so wäre mit der Filterparameter-Erzeugungseinrichtung ein Empfänger verbunden, der das Bewegungsprofil vom Kraftfahrzeug empfängt und zur Filterparameter-Erzeugungseinrichtung überträgt. Die Ausgabeeinrichtung wäre dann eine Sendereinrichtung, um die selektierte Verkehrsinformation zum anfragenden Kraftfahrzeug zu übertragen. Die Filterparameter-Erzeugungseinrichtung könnte in diesem Fall aber auch im Kraftfahrzeug untergebracht sein, so daß dann nur die Filterparamater zur sendeseitig vorhandenen Filtereinrichtung zu übertragen wären.If, on the other hand, the device were to be arranged on the transmitter side, then would be with the filter parameter generating device is connected to a receiver, which receives the motion profile from the motor vehicle and to the filter parameter generating device transmits. The output device would be then a transmitter device to the selected traffic information to transmit to the requesting motor vehicle. The filter parameter generator could in this case also in the motor vehicle be housed so that then only the filter parameters to the transmission side existing filter device would be transferred.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung näher erläutert. Es zeigen:

  • Figur 1 ein Blockschaltbild einer Vorrichtung zum Selektieren von Verkehrsinformation, die in einem Kraftfahrzeug installiert ist;
  • Figur 2 ein beim Start des Kraftfahrzeugs ausgewählter Bereich für relevante Verkehrsinformation; und
  • Figur 3 aktuell ausgewählte Bereiche für relevante Verkehrsinformation bei Fahrt des Kraftfahrzeugs zu einem entfernteren Ziel.
    • An embodiment of the invention is explained below with reference to the drawing. Show it:
  • FIG. 1 shows a block diagram of a device for selecting traffic information, which is installed in a motor vehicle;
  • FIG. 2 shows an area for relevant traffic information selected when the motor vehicle is started; and
  • FIG. 3 currently selected areas for relevant traffic information when the motor vehicle is traveling to a more distant destination.

    • Entsprechend der Figur 1 befindet sich innerhalb eines Kraftfahrzeugs 1 ein Telematik-Endgerät 2, von dem nur die für die Erfindung relevanten Blöcke dargestellt sind. Zum Telematik-Endgerät 2 gehört eine Filtereinrichtung 3, die in Abhängigkeit von Filterparametern ihr zugeführte Verkehrsinformation 4 filtert. Gefilterte Verkehrsinformation 5 gelangt dann zu einer Ausgabeeinrichtung 6, die ausgangsseitig mit der Filtereinrichtung 3 verbunden ist und zur Ausgabe der gefilterten Verkehrsinformation 5 dient, etwa auf optischem oder akustischem Wege.According to FIG. 1, there is a motor vehicle 1 a telematics terminal 2, of which only those relevant to the invention Blocks are shown. A filter device belongs to the telematics terminal 2 3, the traffic information supplied to it as a function of filter parameters 4 filters. Filtered traffic information 5 then arrives to an output device 6, the output side with the filter device 3 is connected and for outputting the filtered traffic information 5 serves, for example optically or acoustically.

    In welcher Weise die der Filtereinrichtung 3 zugeführte Verkehrsinformation 4 gefiltert wird, hängt von Filterparametern 7 ab, die von einer Filterparameter-Erzeugungseinrichtung 8 ausgegeben und zur Filtereinrichtung 3 übertragen werden. Diese Filterparameter 7 finden Eingang in einen Filteralgorithmus, der von der Filtereinrichtung 3 zur Filterung der Verkehrsinformation 4 ausgeführt wird. Bei der Verkehrsinformation 4 handelt es sich um kodierte Information dahingehend, daß sie eine Angabe über den Ort enthält, für den sie gilt. Die Verkehrsinformation 4 ist in einem Verkehrsinformationsspeicher 10 zwischengespeichert. in den ständig aktualisierte Verkehrsinformation 4 von zum Beispiel öffentlichen Sendern neu gespeichert wird, wobei nicht mehr gültige Verkehrsinformation gelöscht bzw. überschrieben wird.How the traffic information supplied to the filter device 3 4 is filtered depends on filter parameters 7, which are generated by a filter parameter generating device 8 output and to the filter device 3 are transmitted. These filter parameters 7 find their way into one Filter algorithm by the filter device 3 for filtering the Traffic information 4 is executed. With traffic information 4 it is encoded information in that it is an indication about the place to which it applies. The traffic information 4 is in one Traffic information memory 10 buffered. in the constantly updated traffic information 4 from, for example, public Transmitters is saved again, traffic information no longer valid is deleted or overwritten.

    Eingangsseitig ist mit der Filterparameter-Erzeugungseinrichtung 8 eine Einrichtung 9 zur Lieferung eines Bewegungprofils des Kraftfahrzeugs 1 verbunden. Bei dieser Einrichtung 9 kann es sich zum Beispiel um eine solche handeln, die das Bewegungsprofil des Kraftfahrzeugs 1 unmittelbar erfaßt, also lokal ist. Sie muß nicht die absolute Position des Fahrzeugs detektieren. Hierfür stehen andere Einrichtungen zur Verfügung, beispielsweise ein GPS-Empfänger, oder dergleichen. Vielmehr genügt es, wenn die Einrichtung 9 nur die momentanen Richtungs- und Geschwindigkeitswerte des Kraftfahrzeugs detektiert. Von diesen Richtungs- und Geschwindigkeltswerten, aus denen auch mittlere Richtungen und Geschwindigkeitswerte ermittelt werden können, werden dann durch die FilterparameterErzeugungseinrichtung 8 die zugehörigen Filterparameter 7, etwa anhand einer geeigneten Tabelle, ausgewählt.On the input side there is a filter parameter generating device 8 Device 9 for delivering a movement profile of the motor vehicle 1 connected. This device 9 can, for example, be a act such that the movement profile of the motor vehicle 1 directly recorded, that is local. It does not have to detect the absolute position of the vehicle. Other facilities are available for this, for example a GPS receiver, or the like. Rather, it is sufficient if the Device 9 only the current direction and speed values of the motor vehicle is detected. From these directional and speed values, from which also mean directions and speed values can then be determined by the filter parameter generating device 8 the associated filter parameters 7, for example an appropriate table.

    Nachfolgend soll die Wirkungsweise der in Figur 1 beschriebenen Vorrichtung im einzelnen beschrieben werden. Dies erfolgt unter Heranziehung der Figuren 2 und 3. The mode of operation of the device described in FIG. 1 is shown below are described in detail. This is done using of Figures 2 and 3.

    Steigt der Fahrer in sein Kraftfahrzeug 1 ein und möchte auf seine individuelle Fahrtroute bezogene Verkehrsinformation erhalten, etwa von einer Sendestation, die an die Masse der Verkehrsteilnehmer regelmäßig für einen sehr großen geographischen Bereich gültige Verkehrsinformation überträgt, so braucht er lediglich sein Fahrzeug zu starten und die Fahrt zu beginnen, wodurch die erfindungsgemäße Vorrichtung initialisiert wird. Schon nach kurzer Zeit erreicht ihn die erste gefilterte Verkehrsinformation, die auf der Ausgabeeinrichtung 6 zum Beispiel angezeigt wird.If the driver gets into his motor vehicle 1 and wants to change his individual Get route-related traffic information, such as from a Transmitting station that is sent to the mass of road users regularly for one very large geographical area valid traffic information he only needs to start his vehicle and start the journey to begin, whereby the device according to the invention initializes becomes. After a short time, the first filtered traffic information reaches him, which is displayed on the output device 6, for example.

    Ohne Filterung würde ihm Verkehrsinformation übermittelt werden, die für einen Bereich mit einem Radius von beispielsweise 100 km um sein Kraftfahrzeug herum gültig wäre. Nach der Erfindung wird ihm jedoch nur Verkehrsinformation 5 übermittelt, die durch Filterung der empfangenen Verkehrsinformation 4 erhalten worden ist und für denjenigen Bereich gilt, in welchem sich das Fahrzeug auch tatsächlich bewegt. Der von der Filtereinrichtung 3 ausgeführte Filteralgorithmus arbeitet dynamisch und verbessert sich fortlaufend, so daß sich die Qualität des Filterresultats mit zunehmender Fahrtzeit des Kraftfahrzeugs erhöht.Without filtering, traffic information would be transmitted to him for an area with a radius of, for example, 100 km around Motor vehicle would be valid around. According to the invention, however, it is only Traffic information 5 transmitted by filtering the received Traffic information 4 has been obtained and for that area applies in which the vehicle actually moves. The one from the Filter device 3 executed filter algorithm works dynamically and continuously improves so that the quality of the filter result increases with increasing travel time of the motor vehicle.

    Kurz nach Start des Kraftfahrzeugs liegen noch keine Meßdaten von der Einrichtung 9 vor, so daß die Filterparameter 7 zunächst auf einen vorbestimmten Anfangswert gesetzt werden. Dieser Anfangswert charakterisiert einen kreisförmigen Bereich 11 um das Kraftfahrzeug 1 herum und weist einen vorbestimmten Radius R auf, wie in Figur 2 gezeigt. Die gesamte empfangene Verkehrsinformation 4 wird dabei mit Hilfe der Filtereinrichtung 3 gefiltert. Der vorbestimmte Radius R weist dabei eine mittlere Größe von beispielsweise 50 km auf, da zu diesem Zeitpunkt noch nicht genau bekannt ist, ob sich das Kraftfahrzeug nur lokal bewegen wird oder eine Fernfahrt beabsichtigt ist.Shortly after starting the motor vehicle, there are still no measurement data from the Device 9 before, so that the filter parameters 7 initially to a predetermined Initial value. This initial value characterizes a circular area 11 around the motor vehicle 1 and has a predetermined radius R, as shown in Figure 2. The whole received traffic information 4 is thereby using the filter device 3 filtered. The predetermined radius R has an average one Size of 50 km, for example, because at this point it is not yet precise it is known whether the motor vehicle will only move locally or one Long-distance travel is intended.

    Nachdem das Fahrzeug eine kurze Zeit gefahren ist, werden von der Einrichtung 9 die ersten Bewegungsdaten an die Filterparameter-Erzeugungseinrichtung 8 geliefert. Fährt zum Beispiel das Fahrzeug mit relativ niedriger mittlerer Geschwindigkeit und treten relativ hohe mittlere Richtungsänderungen auf, so wird anhand dieser Meßgrößen in der Filterparameter-Erzeugungseinrichtung 8 festgestellt, daß sich das Fahrzeuginnerhalb eines City-Bereichs befindet. Infolgedessen werden die Filterparameter 7 entsprechend eingestellt, und zwar auf einen Kreis 12 um das Kraftfahrzeug herum mit einem Radius R1, der beispielsweise bei etwa 25 km liegt, wie in Figur 3 zu erkennen ist. Hier kann es sich um den minimalen Radius handeln. Solange sich an der mittleren Geschwindigkeit und der mittleren Richtungsabweichung nichts ändert, wird also dem Fahrer des Kraftfahrzeugs nur Verkehrsinformation übermittelt, die sich ausschließlich auf diesen kleinen Bereich 12 bezieht. Verkehrsinformation 4 für Bereiche außerhalb dieses kreisförmigen Bereichs wird unterdrückt; sie bleibt aber im Verkehrsinformationsspeicher 10 solange gespeichert, bis sie überschrieben wird.After the vehicle has been driven for a short time, the device will start 9 the first movement data to the filter parameter generation device 8 delivered. For example, drives the vehicle with relative low average speed and occur relatively high average changes in direction on, is based on these measured variables in the filter parameter generating device 8 found that the vehicle is inside a city area. As a result, the filter parameters 7 set accordingly, namely on a circle 12 around the motor vehicle around with a radius R1, for example at about 25 km lies, as can be seen in Figure 3. This can be the minimum Act radius. As long as the medium speed and the mean directional deviation does not change, the driver of the Motor vehicle only transmits traffic information that is exclusive relates to this small area 12. Traffic information 4 for areas outside of this circular area is suppressed; she but remains stored in the traffic information memory 10 until it is overwritten.

    Liegt dagegen die mittlere Fahrzeuggeschwindigkeit bei einem relativ hohen Wert (oberhalb eines vorgegebenen mittleren Geschwindigkeitswertes) und ist die mittlere Richtungsabweichungrelativ klein bzw. kleiner als eine vorgegebene mittlere Richtungsabweichung, so werden durch die Filterparameter-Erzeugungseinrichtung 8 geeignete andere Filterparameter 7 ausgewählt, um Verkehrsinformation nur für einen Bereich zu empfangen, der sich im wesentlichen in der jetzt gültigen mittleren Fahrtrichtung des Fahrzeugs erstreckt. Es handelt sich hier um den Bereich 13 in Figur 3. Zusätzlich dazu wird noch Information für den Bereich 12 zum Fahrer übermittelt. Insgesamt werden somit die Filterparameter 7 so eingestellt, daß Information für die in Figur 3 gezeigten Bereiche 12 und 13 erhalten wird, also für einen im wesentlichen schlüssellochförmigen Bereich. Der Gesamtbereich 12, 13 ist im wesentlichen gekennzeichnet durch den Radius R1, die mittlere bzw. geschätzte Fahrtrichtung und einen auf diese mittlere Fahrtrichtung bezogenen geschätzten bzw. vorgegebenen Öffnungswinkel W.In contrast, the average vehicle speed is a relatively high one Value (above a predetermined average speed value) and the mean directional deviation is relatively small or smaller than a predetermined mean directional deviation, so by the filter parameter generating device 8 other suitable filter parameters 7 selected to receive traffic information for only one area, which is essentially in the mean direction of travel now valid of the vehicle. This is area 13 in FIG 3. In addition, information for area 12 becomes the driver transmitted. Overall, the filter parameters 7 are thus set so that information is obtained for the areas 12 and 13 shown in FIG for a substantially keyhole-shaped area. The Overall area 12, 13 is essentially characterized by the radius R1, the average or estimated direction of travel and one based on this average Estimated or specified opening angle related to the direction of travel W.

    Nach der Erfindung wird die Selektion der Verkehrsinformation wiederholt durchgeführt, wobei die entsprechenden Daten hinsichtlich der Geschwindigkeit und der Richtungsabweichung über jeweils einen Zeitraum von etwa 10 Minuten gesammelt werden können, um daraus die mittleren Werte zu erhalten. Der zeitliche Mindestabstand der Selektion kann daher auch 10 Minuten oder mehr betragen, so daß bei Fahrt zum Beispiel auf einer Autobahn die schlüssellochförmige Bereichsstruktur 11, 12 wiederholt generiert wird. Somit werden die Filterparameter wiederholt generiert, um ständig die Möglichkeit zu haben, auf den jeweiligen Ort des Kraftfahrzeugs bezogene Verkehrsinformation dem Fahrer übermitteln zu können.According to the invention, the selection of the traffic information is repeated performed, the corresponding data regarding speed and the directional deviation over a period of time of about 10 minutes can be collected to get the mean To get values. The minimum time interval for the selection can therefore also be 10 minutes or more, so that when driving for example on a Autobahn repeated the keyhole-shaped area structure 11, 12 is generated. Thus the filter parameters are generated repeatedly, to always have the opportunity to go to the respective location of the Transport-related traffic information to the driver can.
