The US-PS 48 12 843 describes a traffic information system in which a normal channel with digi taler transmission is provided with the computer data be transferred via a modem, or a modula tion of the carrier frequency transmits the information.  

Derartige Systeme zur Übertragung von individuellen Ver­ kehrsinformationen sind aufwendig und belegen Platz in dem knappen Frequenzband.Such systems for the transmission of individual Ver Traffic information is complex and occupies space in the narrow frequency band.

Weiterhin ist es bekannt, Verkehrsinformationen herkömm­ licher Weise über Autoradios zu verbreiten.It is also known to convention traffic information spread over car radios.

Aufgabe der Erfindung ist es, die Information der Auto­ fahrer zur Verkehrslage zu verbessern.The object of the invention is the information of the car driver to improve traffic.

Verkehrsinformationen werden in herkömmlicher Weise bislang über Autoradios oder andere Medienträger ver­ breitet.Traffic information is sent in a conventional manner hitherto ver via car radios or other media carriers spreads.

Aufgabe der Erfindung ist es, die Information der Auto­ fahrer zur Verkehrslage zu verbessern.The object of the invention is the information of the car driver to improve traffic.

Die Aufgabe wird gelöst durch die kennzeichnenden Merkmale im Anspruch 1.The task is solved by the characteristic features in claim 1.

Erfindungsgemäß ist vorgesehen, daß der Organisationska­ nal zwischen Zentrale und mobilem Telefon herangezogen wird nicht nur zur Organisation der Telefongespräche, sondern gleichzeitig zur Übersendung von Informationen, die mehreren mobilen Telefonen gleichzeitig zugehen. Da­ bei handelt es sich in erster Linie um Verkehrsinfor­ mationen, die in üblicher Art zur Anzeige gebracht wer­ den können, entweder auf einem Display, das dem Telefon zugeordnet ist, oder aber auch akustisch über Lautspre­ cher entsprechend der bisherigen Verbreitung von Ver­ kehrsinformationen über Autoradio.According to the invention it is provided that the organizational box between central and mobile phone will not only be used to organize the phone calls, but at the same time to send information, the multiple mobile phones answer at the same time. There is primarily traffic information mations that are displayed in the usual way can, either on a display that the phone is assigned, or also acoustically via loudspeaker according to the prevalence of Ver Traffic information about car radio.

Auch die Ansteuerung weiterer Anzeigegeräte, z. B. für die zu wählende Fahrtrichtung, liegt im Rahmen der Er­ findung. The control of other display devices such. B. for the direction of travel to be selected is within the Er finding.  

In einer bevorzugten Ausführungsform ist ein Speicher vorgesehen, der mit dem Autotelefon verbunden wird, um die Verkehrsinformationen jeweils zu speichern und sie dementsprechend auf Abfrage erstmalig oder erneut anzu­ zeigen.In a preferred embodiment is a memory provided, which is connected to the car phone to save the traffic information each and them accordingly, to be requested for the first time or again demonstrate.

In einer Weiterbildung der Erfindung ist nicht nur vor­ gesehen, daß Verkehrsmeldungen, wie sie beispielsweise von Zentralverkehrsrechnern, von Polizei-Einsatzfahrzeu­ gen und ähnlichem angegeben werden, über den Organisa­ tionskanal weitergereicht werden, sondern umgekehrt läßt sich durch eine entsprechende Logikeinheit auch die Be­ wegung des Fahrzeuges erfassen und somit abfragen, ob es beispielsweise in einem Stau steht. Diese Informationen, die automatisch erfaßt werden und sich aus der Geschwin­ digkeit und ggf. auch aus der Feststellung, an welchem Ort sich das Fahrzeug befindet, zusammengesetzt sind, können - analog oder noch günstiger digital - an die Zentrale weitergeleitet werden, um dort von einem Rech­ ner ausgewertet zu werden, der aus der Vielzahl der Einzelinformationen ein Gesamtbild über die Verkehrsbe­ lastung z. B. eines bestimmten Straßenzuges gewinnt. Diese von dem Rechner in der Zentrale ermittelte Ver­ kehrssituation kann, sozusagen als Rückkoppelung, wieder an die Autofahrer zurückgegeben werden, so daß eine wei­ tere Belastung eines bereits überlasteten Straßenzuges vermieden werden kann.In a further development of the invention is not just before seen that traffic reports, such as from central traffic computers, from police emergency vehicles conditions and the like can be specified via the Organisa tion channel are passed on, but vice versa the Be Record the movement of the vehicle and thus query whether it is for example in a traffic jam. This information, which are automatically detected and derived from the speed and possibly also from the determination of which Where the vehicle is located, are assembled, can - analog or even cheaper digital - to Head office to be forwarded to there by a rech ner to be evaluated from the multitude of Individual information an overall picture of the traffic area load z. B. wins a certain street. This Ver determined by the computer in the headquarters Reverse situation can, so to speak, as a feedback again be returned to the driver, so that a white lower load on an already overloaded street can be avoided.

In einer weiteren Ausgestaltung ist die Kombination der Informationen sowohl von einer Verkehrsleitzentrale als auch von den Einzelfahrzeugen denkbar, wobei hinzukommt, daß durch das Autotelefonsystem stets eine Standortbe­ stimmung der einzelnen mobilen Telefone stattfindet, so daß die Ortung von Verkehrsknotenpunkten und Stellen, in denen der Verkehr zum Erliegen gekommen ist, möglich ist.In a further embodiment, the combination of Information from both a traffic control center and also conceivable from the individual vehicles, with the addition that through the car phone system always a location mood of the individual mobile phones takes place, so  that the location of transport hubs and locations in to which traffic has come to a standstill is.

Da ein Autotelefonsysstem zellular aufgebaut ist, ist die Verkehrsdurchsage für einen sehr engen und genau abgrenzbaren Bereich möglich, so daß dem Autofahrer wirklich die nur ihn unmittelbar betreffenden Verkehrs­ nachrichten zugeleitet werden können. Damit ist eine hochgradig individualisierte Informationsversorgung möglich.Because a car phone system is cellular the traffic announcement for a very narrow and accurate delimitable area possible, so that the driver really the traffic that directly affects him messages can be forwarded. So that's one highly individualized information supply possible.

Im folgenden wird die Erfindung anhand der Figur erläu­ tert. In der einzigen Figur ist schematisch das Autote­ lefonnetz dargestellt, das eine Zentrale 10 auffaßt. In der Zentrale 10 ist eine Sende- und Empfangsanlage 12 und eine zugehörige Auswerteinheit 14 vorgesehen. Über eine Antenne 16 sendet und empfängt die Sende-/Empfangs­ anlage 12 über Funkkontakte 18a, 18b und 18c Informa­ tionen von mobilen Telefoneinheiten 20a, 20b und 20c.In the following the invention is tert tert with reference to the figure. In the single figure, the car telephone network is shown schematically, which a central office 10 . A transmitter and receiver system 12 and an associated evaluation unit 14 are provided in the control center 10 . Via an antenna 16 , the transmitting / receiving system 12 sends and receives information from mobile telephone units 20 a, 20 b and 20 c via radio contacts 18 a, 18 b and 18 c.

Diese sind schematisch dargestellt durch einen Telefon­ hörer 22a, 22b und 22c, der jeweils einem Fahrzeug 24a, 24b und 24c zugeordnet ist. Über eine Antenne 26a, 26b und 26c wird die Funkverbindung 18a, 18b und 18c mit der Antenne 16 der Zentrale 10 aufrechterhalten.These are shown schematically by a telephone handset 22 a, 22 b and 22 c, which is assigned to a vehicle 24 a, 24 b and 24 c. The radio connection 18 a, 18 b and 18 c with the antenna 16 of the control center 10 is maintained via an antenna 26 a, 26 b and 26 c.

Den Telefonen 22a, 22b und 22c sind Logikeinheiten 28a, 28b und 28c zugeordnet, die Fahrzeugsbetriebsparameter und ggf. auch eine Standortbestimmung vornehmen. Damit ist es möglich, an die Zentrale die Information, wo sich das Auto befindet und mit welcher Geschwindigkeit es bewegt wird, zu übertragen. Durch eine entsprechende rechnerische Erfassung und Vergleich mit anderen Fahr­ zeugen läßt sich feststellen, ob sich das Fahrzeug in einem Stau befindet, und wo ggf. dieser Stau sich aufge­ baut hat. Gleichzeitig kann ermittelt werden, in welchen Straßenzügen des überwachten Gebietes ein möglichst schnelles Vorankommen im Stadtverkehr möglich ist.Logic units 28 a, 28 b and 28 c are assigned to telephones 22 a, 22 b and 22 c, which carry out vehicle operating parameters and possibly also determine a location. This makes it possible to transmit information to the head office on where the car is and at what speed it is being moved. By means of a corresponding computational recording and comparison with other driving witnesses it can be determined whether the vehicle is in a traffic jam and where this traffic jam has possibly built up. At the same time it can be determined in which streets of the monitored area the fastest possible progress in city traffic is possible.

Diese Informationen lassen sich über die Funkstrecke 18a, 18b und 18c zurückübertragen auf die einzelnen Fahrzeuge 24a, 24b und 24c, wo sie in einem Display 30a, 30b oder 30c, ggf. auch akustisch über Lautsprecher 32a, 32b und 32c angezeigt werden können.This information can be transmitted back over the radio link 18 a, 18 b and 18 c to the individual vehicles 24 a, 24 b and 24 c, where it is shown in a display 30 a, 30 b or 30 c, possibly also acoustically via loudspeaker 32 a, 32 b and 32 c can be displayed.

Den Anzeigeeinheiten 30a, 30b, 30c bzw. 32a, 32b, 32c kann auch ein Speicher zugeordnet werden, der auf Abruf die Information wiederholen läßt.The display units 30 a, 30 b, 30 c and 32 a, 32 b, 32 c can also be assigned a memory which allows the information to be repeated on demand.

Durch das erfindungsgemäße System kann in der ersten Aufbaustufe ein mit geringem Aufwand erstellbares System zur gezielten Verkehrsinformation geschaffen werden, da der Organisationskanal zwischen der Zentrale und den einzelnen Telefonen ohnehin vorhanden ist und für die Übertragung von digitalen Daten zur Verfügung steht, ohne daß er überlastet wird. Der mit der Codierung und die Codierung der übermittelten Nachrichten verbundene Aufwand ist vertretbar.The system according to the invention can be used in the first Advanced level a system that can be created with little effort for targeted traffic information, because the organizational channel between the headquarters and the individual phones is there anyway and for that Transmission of digital data is available without being overloaded. The one with the coding and the coding of the transmitted messages related Effort is justifiable.

In einer zweiten Aufbaustufe kann durch die Informatio­ nen vom Fahrzeug eine sehr effektive Überwachung des Verkehrs erfolgen, da größere Ansammlungen von stehenden Fahrzeugen sofort erfaßt werden. Diese Überwachung kommt auch den Fahrzeugen zugute, die nicht mit Autotelefonen ausgerüstet sind, denn ein Stau beispielsweise auf der Autobahn wird auf diese Weise sehr schnell und frühzei­ tig erfaßt und kann durch entsprechende Runkfunkmeldung sofort an Autofahrer, die Verkehrsfunk hören, weiterbe­ richtet werden.In a second stage of development, the Informatio effective monitoring of the vehicle Traffic occurs as there are larger collections of standing Vehicles can be detected immediately. This surveillance is coming also benefits vehicles that do not have car phones are equipped because a traffic jam on the  In this way, the motorway becomes very quick and early tig recorded and can by appropriate radio communication immediately to drivers who listen to traffic reports be judged.
