Abstract
Description
Die Erfindung betrifft ein Verfahren zur Ermittlung von Verkehrsinformationen unter Verwendung von in einem Kraftfahrzeug mit Sensoren erfaßten Daten, die von dem Kraftfahrzeug mit einer Sendeeinrichtung kommuniziert werden. Die Erfindung betrifft ferner ein Telematikgerät für ein Kraftfahrzeug mit Eingängen zum Anschluß von Sensoren des Kraftfahrzeugs und mit einer Sendeeinrichtung zur Übertragung von Sensordaten.The invention relates to a method for determining traffic information using in a motor vehicle data recorded with sensors from the motor vehicle with a Transmitting device to be communicated. The invention relates also a telematics device for a motor vehicle with inputs for connecting sensors of the motor vehicle and with a transmitter for the transmission of sensor data.
Das heute praktizierte System der Durchsage von Verkehrsnachrichten ist nicht befriedigend, weil eine erhebliche Zeit benötigt wird, bis relevante Verkehrsereignisse gemeldet und dann über Rundfunk mitgeteilt werden, wobei viele Verkehrsteilnehmer die Durchsage der Verkehrsmeldung verpassen, weil sie gerade zu diesem Zeitpunkt das Autoradio ausgeschaltet oder einen Sender eingestellt haben, der keine Verkehrsnachrichten ausstrahlt.Today's traffic announcement system is not satisfactory because it takes a significant amount of time is reported until relevant traffic events and then can be communicated via radio, with many road users miss the announcement of the traffic announcement because it is currently too At this point the car radio is switched off or a transmitter have stopped broadcasting no traffic news.
Das letztgenannte Problem kann durch die Einrichtung eines Verkehrsfunkkanals behoben werden, dessen jeweils letzte Verkehrsmeldungen in einem Speicher abgespeichert werden und daher jederzeit abgehört werden können. Der Speicher ist dabei so organisiert, daß neu ankommende Meldungen die ältesten abgespeicherten Meldungen aus dem Speicher eliminieren (First-In-First-Out). The latter problem can be solved by setting up a traffic radio channel be fixed, the latest traffic reports be stored in a memory and therefore at any time can be intercepted. The store is organized so that newly arriving messages are the oldest stored Eliminate messages from memory (first-in-first-out).
Es wird erwogen und an Versuchsstrecken erprobt, durch an den Straßen, insbesondere Autobahnen, montierte Sensoren die mittlere Verkehrsdichte und -geschwindigkeit zu detektieren und an eine Zentrale zu melden, die aus den detektierten Daten Verkehrsmeldungen erstellt.It is being considered and tested on test tracks by the Roads, especially highways, mounted sensors in the middle Detect and report traffic density and speed a control center to report traffic reports from the detected data created.
Ergänzend oder alternativ hierzu ist der Gedanke bekannt geworden, durch im Fahrzeug installierte Verkehrstelematik-Endgeräte Position, Fahrgeschwindigkeit und -richtung unmittelbar aus dem Verkehrsgeschehen zu melden (Mannesmann-Geschäftsbericht 1996, veröffentlicht im Internet unter http://www.mannesmann.de./fakten/1996/forschung.htm#automotive). Zur Positionsbestimmung wird dabei das satellitengestützte Global Positioning System GPS und zur Informationsübermittlung an die Zentrale das flächendeckende GSM-Mobilfunknetz genutzt. Die Daten "Fahrgeschwindigkeit und - richtung" können aus der Sensierung der Lenkbewegung und aus dem Sensor für den Tachometer oder den Radsensoren für ein Anti-Blockier-System (ABS) entnommen werden. Dieses FCD-Verfahren (Floating-Car-Data-Verfahren) dient ausschließlich zur Feststellung von Verkehrsstaus und Reisezeiten und zur Erzeugung von Staumeldungen. Damit eine entsprechende Stauwarnung von der Zentrale generiert und ausgesendet werden kann, müssen zahlreiche aktuelle Daten von Verkehrsteilnehmern ausgewertet werden, um mit einer nötigen Sicherheit auf das Vorliegen eines Staus schließen zu können. Hierdurch wird auch beim FCD-Verfahren eine deutliche Reaktionszeit des Systems auftreten, die zwischen dem Auftreten eines Staus und dem Generieren einer entsprechenden Stauwarnmeldung vergeht. Während dieser Reaktionszeit wird der Stau durch weiter in das Staubgebiet einfahrende Fahrzeuge vergrößert und die Gefahr von durch den Stau verursachten Unfällen, insbesondere Auffahrunfällen, nicht beseitigt. Darüber hinaus werden in dem bekannten Verfahren andere unfallträchtige Umstände nicht berücksichtigt, wie beispielsweise lokale Glättestellen durch Glatteis, Ölspuren o.ä.In addition or as an alternative to this, the idea has become known thanks to traffic telematics devices installed in the vehicle Position, driving speed and direction directly from the Report traffic events (Mannesmann Annual Report 1996, published on the Internet at http://www.mannesmann.de./fakten/1996/forschung.htm#automotive). To determine the position the satellite-based Global Positioning System GPS and for the transmission of information to the head office GSM cellular network used. The data "driving speed and - direction "can from the sensation of the steering movement and from the Sensor for the speedometer or the wheel sensors for an anti-lock braking system (ABS) can be removed. This FCD procedure (Floating car data procedure) is used only for the determination of traffic jams and travel times and for the generation of Traffic reports. So that a corresponding traffic jam warning from the Central can be generated and sent out numerous current data from road users are evaluated, to be sure of the presence of a traffic jam to be able to close. This also means that the FCD significant system response time that occurs between the Occurrence of a traffic jam and the generation of a corresponding Traffic jam warning passes. During this reaction time the Traffic jam enlarged by vehicles entering the dust area and the risk of accidents caused by traffic jams, especially rear-end collisions, not eliminated. Furthermore are other accident-prone circumstances in the known method not taken into account, such as local smoothing points due to black ice, traces of oil or similar
Der vorliegenden Erfindung liegt daher das Problem zugrunde, eine noch schnellere Warnung der Verkehrsteilnehmer zu ermöglichen, die sich auch auf über die Staubildung hinausgehende Gefahrensituationen erstrecken kann. The present invention is therefore based on the problem enable an even faster warning of road users, which also applies to dangerous situations that go beyond congestion can extend.
Zur Lösung dieses Problems ist erfindungsgemäß ein Verfahren der eingangs erwähnten Art dadurch gekennzeichnet, daß Kraftfahrzeuge mit Empfangseinrichtungen für die kommunizierten Daten ausgestattet werden und daß typischerweise Gefahrensituationen zuzuordnende Sensordaten auf kurzem Weg von Fahrzeug zu Fahrzeug übertragen und im empfangenden Kraftfahrzeug zu einem Warnsignal verarbeitet werden.To solve this problem, a method according to the invention is initially mentioned type characterized in that motor vehicles with receiving devices for the communicated data be equipped and that typically dangerous situations assignable sensor data on a short way from vehicle to vehicle transmitted and in the receiving motor vehicle to a warning signal are processed.
Das erfindungsgemäße Verfahren beruht darauf, daß modernere Kraftfahrzeuge bereits mit einer so umfangreichen Sensorik ausgestattet sind, daß die von dem Kraftfahrzeug bordeigenen erstellten Sensordaten bereits Aufschlüsse über Gefahrensituationen geben können, wenn diese Daten von Fahrzeug zu Fahrzeug auf nachfolgende Kraftfahrzeuge übertragen werden. Dies gilt naturgemäß für das Signal eines Crash-Sensors, der das Auslösen eines Airbags steuert, wenn das Fahrzeug auf ein Hindernis aufprallt. Die Übermittlung des Signals des Crash-Sensors ggf. ergänzt um eine hiermit übertragene Meldung an nachfolgende Fahrzeuge kann naturgemäß eine effektive Warnung dieser Fahrzeuge bewirken und das Entstehen von Auffahrunfällen durch in einen Unfall verwickelte Fahrzeuge verringert werden. Gleiches gilt für durch eine Panne auf einer Fahrspur liegen gebliebene Fahrzeuge, an denen regelmäßig in diesem Fall die Warnblinkanlage eingeschaltet wird. Das Einschalten der Warnblinkanlage kann in dem Kraftfahrzeug sensiert und als entsprechendes Signal an nachfolgende Fahrzeuge mittels einer Fahrzeug-Fahrzeug-Kommunikation übermittelt werden. In gleicher Weise funktioniert eine Warnung vor Hindernissen auf Fahrspuren, die beispielsweise durch eine von einem Lastkraftwagen herabgefallene Ladung entstehen, indem das Ausgangssignal eines Bremssensors, beispielsweise die Einschaltung der ABS-Steuerung (Stotterbremsung) sensiert und als Signal für eine Vollbremsung übermittelt wird. Im empfangenden Kraftfahrzeug können diese Signale zu speziellen Warnsignalen in optischer und/oder akustischer Form und gegebenenfalls zu entsprechenden Anzeigen auf einem Display verarbeitet werden. The inventive method is based on the fact that more modern Motor vehicles are already equipped with such extensive sensors are that the on-board created by the motor vehicle Sensor data already provides information about dangerous situations can give up if this data from vehicle to vehicle subsequent motor vehicles are transmitted. This naturally applies for the signal of a crash sensor that triggers a Airbags control when the vehicle hits an obstacle. The transmission of the signal from the crash sensor may be supplemented by a message transmitted hereby to subsequent vehicles naturally cause an effective warning of these vehicles and the occurrence of rear-end collisions caused by an accident Vehicles are reduced. The same applies to one Breakdowns in a lane are vehicles that have remained In this case, the hazard warning lights are switched on regularly becomes. The hazard lights can be switched on in the motor vehicle sensed and as a corresponding signal to subsequent Vehicles transmitted using vehicle-to-vehicle communication become. A warning works in the same way Obstacles in lanes, for example by one of a load that has fallen on a truck is caused by the Output signal of a brake sensor, for example the activation the ABS control (stutter braking) senses and as a signal is transmitted for emergency braking. In the receiving motor vehicle can turn these signals into special warning signals optical and / or acoustic form and, if necessary, corresponding Ads processed on a display.
Durch die Erfindung werden daher Sensorsignale, die in vorhergehenden Fahrzeugen entstehen, für nachfolgende Fahrzeuge zur Warnung des Fahrers verfügbar. Hierdurch läßt sich bereits eine effektive Warnung vor speziellen Gefahrensituationen erreichen.The invention therefore sensor signals in previous Vehicles are created for subsequent vehicles Driver warning available. This can already be a achieve an effective warning of special dangerous situations.
In manchen Fällen bedarf es jedoch erst einer Auswertung von für sich noch nicht bedeutungsvollen verschiedenen Sensorsignalen, die im eigenen oder in einem vorherfahrenden Fahrzeug generiert worden sind, um eine Gefahrensituation zu erkennen. In einer bevorzugten Ausführungsform der Erfindung ist daher das Kraftfahrzeug mit einer bordeigenen Intelligenz ausgestattet, die eine Auswertung der eigenen und/oder empfangenen Sensordaten ermöglicht und eine eigene Warnmeldung an den Fahrer generiert. So kann beispielsweise das Abfallen der Außentemperatur auf unter 0°C in Verbindung mit einem übertragenen Signal für die Betätigung des Lichtschalters dahingehend interpretiert werden, daß eine erhöhte Glatteisgefahr besteht, da die Betätigung des Lichtschalters mit großer Sicherheit auf eine verminderte Sicht durch Niederschläge oder durch Nebel zurückzuführen ist. In diesen Fällen ist eine Glättebildung sehr wahrscheinlich.In some cases, however, an evaluation of for is required not yet meaningful different sensor signals, generated in your own vehicle or in a preceding vehicle have been made to recognize a dangerous situation. In a The preferred embodiment of the invention is therefore the motor vehicle equipped with an onboard intelligence that an evaluation of your own and / or received sensor data enables and generates its own warning message to the driver. For example, the outside temperature may drop below 0 ° C in connection with a transmitted signal for the Actuation of the light switch can be interpreted as that there is an increased risk of black ice, since the operation of the Light switch with great certainty on a reduced view is due to precipitation or fog. In In these cases, smoothness is very likely.
In die Erstellung der bordeigenen Warnmeldung können selbstverständlich anderweitig empfangene Verkehrsinformationen einbezogen werden, die beispielsweise über einen Verkehrsfunkkanal in kodierter, d.h. automatisch auswertbarer Form ausgestrahlt werden.Of course, in the creation of the on-board warning message other traffic information received included be, for example, on a traffic radio channel in encoded, i.e. automatically evaluable form are broadcast.
Besonders zweckmäßig ist es, wenn ein Kraftfahrzeug die eigenen und/oder empfangenen Sensordaten zusammen mit Positionsinformationen an eine Zentrale überträgt, die die Sensordaten auswertet und Verkehrswarnmeldungen an an sie angeschlossene Verkehrsteilnehmer aussendet. Dabei ist es möglich, die nackten Sensordaten oder auch die bereits an Bord vorausgewerteten Sensordaten zu übermitteln. Die Zentrale kann beispielsweise durch einen Service-Provider in einem Mobilfunknetz gebildet sein, bei dem zahlreiche Daten zur Verkehrs- und Wetterlage einlaufen und bei dem daher eine umfangreiche Auswertung und zuverlässigere Erstellung von Verkehrswarnmeldungen möglich ist.It is particularly useful if a motor vehicle has its own and / or received sensor data together with position information transmits to a control center, which evaluates the sensor data and traffic warnings to road users connected to them sends out. It is possible to use the bare sensor data or the sensor data already pre-evaluated on board to transfer. The head office can, for example, by a service provider be formed in a mobile network in which numerous Data on traffic and weather conditions arrive at the therefore an extensive evaluation and more reliable creation of traffic warnings is possible.
Zur Durchführung des erfindungsgemäßen Verfahrens eignet sich ein erfindungsgemäßes Telematikgerät der eingangs erwähnten Art, das gekennzeichnet ist durch eine Empfangseinrichtung zum Empfang von von Telematikgeräten anderer Fahrzeuge übertragenen Sensordaten und eine Auswertungseinrichtung zur Abgabe von Warnsignalen aufgrund bordeigener und/oder empfangener Sensordaten.It is suitable for carrying out the method according to the invention an inventive telematics device of the type mentioned at the beginning, that is characterized by a receiving device for Reception of telematics equipment from other vehicles Sensor data and an evaluation device for emitting warning signals due to on-board and / or received sensor data.
Dabei kann das Telematikgerät insbesondere zum Anschluß eines Crash-Sensors, eines Indikators für das Einschalten der Warnblinkanlage und/oder eines eine ABS-Regelung indizierenden Bremssensors eingerichtet sein.The telematics device can in particular be used to connect a Crash sensor, an indicator for switching on the hazard lights and / or one that indicates an ABS regulation Brake sensor can be set up.
Zur Erkennung von Gefahrensituationen aus einer Mehrzahl von Sensordaten kann das erfindungsgemäße Telematikgerät eine Auswertungseinrichtung zur Auswertung zahlreicher eigener und/oder empfangener Sensordaten und zum Generieren und Ausgeben einer Warnmeldung an den Fahrer ausgebildet sein. An die Auswertungseinrichtung kann dabei ein Speicher für anderweitig in kodierter Form empfangene Verkehrsinformationen geschlossen sein.For the detection of dangerous situations from a plurality of The telematics device according to the invention can use sensor data as an evaluation device for the evaluation of numerous own and / or received sensor data and for generating and outputting one Warning message to the driver. To the evaluation facility can be a memory for otherwise encoded Form received traffic information must be closed.
Zur Teilnahme am FCD-Verfahren kann das erfindungsgemäße Telematikgerät zugleich zum Aussenden von eigenen und/oder empfangenen Sensordaten oder von aus deren Auswertung an Bord erstellten Warnhinweisen zusammen mit Positionsdaten an eine Zentrale ausgebildet sein. Die Erstellung von Verkehrswarnmeldungen durch die Zentrale funktioniert auch dann, wenn nur ein gewisser Anteil der Verkehrsteilnehmer die von Fahrzeug zu Fahrzeug übertragenen Sensordaten oder Warnmeldungen an die Zentrale weiterleitet.The telematics device according to the invention can be used to participate in the FCD method at the same time for sending your own and / or received ones Sensor data or data generated from their evaluation on board Warning notices are formed together with position data at a central office be. The creation of traffic alerts by the head office works even if only a certain proportion the road user is the one transmitted from vehicle to vehicle Forwards sensor data or warning messages to the control center.
Die Weiterleitung der Sensordaten an die Zentrale geschieht vorzugsweise mit Hilfe einer Mobilfunk-Sendeeinrichtung, wobei vorzugsweise spezielle standardisierte Kurzmeldungen für die Übertragung der Sensordaten verwendet werden. The sensor data is forwarded to the control center preferably with the aid of a mobile radio transmission device, wherein preferably special standardized short messages for the Transmission of the sensor data can be used.
Die Übertragung von Fahrzeug zu Fahrzeug kann mit einer Sendeeinrichtung mit kurzer Reichweite von wenigen Kilometern erfolgen, so daß alle empfangenen Sensordaten als kurzfristig relevant eingestuft werden können. In diesem Fall ist die Übermittlung einer Positionsangabe möglicherweise entbehrlich. Andernfalls wird es zweckmäßig sein, an das Telematikgerät eine Ortungseinrichtung für die Erstellung von Positionsdaten für das Kraftfahrzeug anzuschließen, so daß mit den Sensordaten auch die zugehörigen aktuellen Positionsdaten des sendenden Kraftfahrzeugs übermittelt werden. Mit Hilfe einer entsprechenden Ortungseinrichtung im empfangenen Kraftfahrzeug kann dann die Entfernung zum aussendenden Kraftfahrzeug festgestellt werden, so daß eine Abschätzung der Aktualität der Warnmeldung problemlos erfolgen kann.The transmission from vehicle to vehicle can be done with a transmitter with a short range of a few kilometers, so that all received sensor data is relevant as short-term can be classified. In this case, the transmission a position specification may be unnecessary. Otherwise it will be useful to locate the telematics device for the creation of position data for the Connect motor vehicle, so that with the sensor data associated current position data of the sending motor vehicle be transmitted. With the help of an appropriate location device in the received motor vehicle can then Distance to the emitting motor vehicle are determined, so that an estimation of the timeliness of the warning message is no problem can be done.
