Description
Die Erfindung betrifft ein Verfahren zur Erstellung von Warnhinweisen für Fahrer eines Kraftfahrzeugs unter Verwendung von Sensordaten aus wenigstens einem am Verkehr teilnehmenden Kraftfahrzeug. Die Erfindung betrifft ferner ein Verkehrswarngerät für ein Kraftfahrzeug zur Ausgabe von Warnhinweisen an den Fahrer.The invention relates to a method for creating warning notices for drivers of a motor vehicle using Sensor data from at least one participating in traffic Motor vehicle. The invention further relates to a traffic warning device for a motor vehicle to issue warning notices the driver.
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 until relevant traffic events are reported and then be broadcast via radio, with many road users miss the announcement of the traffic announcement because they just turned off the car radio at this time or have tuned into a station that does not have traffic information radiates.
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 are fixed, the last traffic reports be stored in a memory and therefore can be listened to at any time. The memory is there organized in such a way that newly arriving messages are saved to the oldest 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 flächende GSM-Mobilfunknetz genutzt. Die Daten "Fahrgeschwindigkeit und -richtung" können auch aus den GPS-Signalen, vorzugsweise aber aus der Sensierung der Lenkbewegung und aus dem Sensor für den Tachometer oder den Radsensoren für ein Antiblockier-System (ABS) entnommen werden. Dieses FCD-Verfahren (Floating-Car-Data-Verfahren) dient ausschließlich zur Feststellung von Verkehrsstaus und zur Erzeugung von Staumeldungen sowie zur Ermittlung und Auswertung von Reisezeiten. 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 through traffic telematics terminals installed in the vehicle Position, driving speed and direction immediately to report on the traffic situation (Mannesmann annual report 1996, published on the Internet at http://www.mannesmann.de./fakten/1996/forschung.htm#automotive). For position determination becomes satellite-based global positioning System GPS and for the transmission of information to the Central uses the extensive GSM mobile network. The data "Driving speed and direction" can also be derived from the GPS signals, but preferably from sensing the steering movement and from the sensor for the speedometer or the wheel sensors for an anti-lock braking system (ABS). This FCD (Floating Car Data) process is used exclusively for the detection of traffic congestion and for the generation of Traffic jam reports and for determining and evaluating travel times. A corresponding traffic jam warning from the head office numerous can be generated and sent current data from road users are evaluated in order with the necessary security for the presence of a traffic jam to be able to close. This also applies to the FCD procedure a significant system response time occur that between the occurrence of a jam and the generation of one corresponding traffic jam warning passes. During this response time the traffic jam is caused by entering the dust area Vehicles magnified and the risk of through the Accidents caused by traffic jams, especially rear-end collisions, not eliminated. In addition, in the known method other accident-prone circumstances are not taken into account, such as local smoothing points due to black ice, traces of oil etc.
Aus der US-A-4 706 086 ist ein Verfahren bekannt bei dem Signale von Fahrzeug zu Fahrzeug ausgetauscht werden. Bei diesen Signalen handlet es sich einerseits um Verkehrszustände (Rückstau, unerwarteter Stop, u.s.w.) und andererseits um meteorologische Informationen (Regen, Nebel u.s.w.). Diese Signale werden in den sendenden Fahrzeugen automatisch aus Sensoren gewonnen. From US-A-4 706 086 a method is known in which signals from vehicles Vehicle can be replaced. On the one hand, these signals are Traffic conditions (backwater, unexpected stop, etc.) and on the other hand around meteorological information (rain, fog, etc.). These signals are in the sending vehicles automatically obtained from sensors.
Der vorliegenden Erfindung liegt das Problem zugrunde, die Erstellung von Warnhinweisen für den Fahrer eines Kraftfahrzeugs noch zu beschleunigen.The present invention addresses the problem that Creation of warnings for the driver of a motor vehicle still speed up.
Dieses Problem wird mit dem Verfahren nach Anspruch 1 und dem Verkehrswarngerät nach Anspruch 2 gelöst.This problem is solved with the method according to
Nach dem erfindungsgemäßen Verfahrens findet eine Übermittlung der jeweiligen Sensordaten von Fahrzeug zu Fahrzeug statt und es werden die Warnhinweise unter Auswertung der in anderen Fahrzeugen erstellten Sensordaten und der bordeigenen Sensordaten erstellt und ausgegeben.According to the invention The respective sensor data is transmitted via the method from vehicle to vehicle instead and there will be warnings evaluating the sensor data created in other vehicles and the on-board sensor data created and output.
Das erfindungsgemäße Verfahren beruht auf der Erkenntnis, daß in modernen Kraftfahrzeugen bereits so viele Sensoren zur Verfügung stehen oder leicht realisierbar sind, deren Ausgangssignale für die Beurteilung verkehrsrelevanter Situationen verwendbar sind, daß eine Auswertung im Fahrzeug zur Erstellung von relevanten Warnhinweisen für den Fahrer möglich ist.The method according to the invention is based on the knowledge that in modern motor vehicles already so many sensors are available or easy to implement are whose output signals are more relevant for the assessment of traffic Situations that can be used are an evaluation in the vehicle to create relevant warnings is possible for the driver.
Beispiele für bereits in vielen Fahrzeugen vorhandene Sensoren dieser Art sind Temperatursensor für die Außentemperatur, Schlupfsensor einer ABS-Steuerung oder einer Traktionsregelung, Lichtschalter, Schalter der Warnblinkanlage, Crash-Sensor eines Airbags, Regen-/Feuchtigkeitssensor einer Scheibenwischersteuerung usw.Examples of sensors already present in many vehicles of this type are temperature sensors for the outside temperature, Slip sensor of an ABS control or a traction control, Light switch, hazard warning light switch, crash sensor of an airbag, rain / moisture sensor of a wiper control etc.
Unter Ausnutzung der Sensorsignale des eigenen Fahrzeugs lassen sich bereits relevante Warnhinweise erzeugen. Noch umfassendere Warnhinweise sind möglich, wenn Sensordaten von Fahrzeug zu Fahrzeug übertragen bzw. ausgetauscht werden, so daß eine größere Informationsbasis für die Erstellung von Warnhinweisen, insbesondere unter Berücksichtigung des vorausfahrenden Verkehrs möglich ist.Leave using your own vehicle's sensor signals relevant warnings are already generated. Even more comprehensive Warnings are possible if sensor data from vehicle be transferred to vehicle or exchanged so that a larger information base for creating warnings, especially taking into account the vehicle in front Traffic is possible.
Die Auswertung der Sensordaten, der bordeigenen und der empfangenen Sensordaten, wird dabei unter Einbeziehung anderweitig empfangener und abgespeicherter verkehrsrelevanter Informationen vorgenommen. Solche anderweitigen Verkehrsinformationen können beispielsweise über einen Verkehrsfunkkanal durch ein Autoradio empfangen und in einem Speicher für aktuelle Verkehrsmeldungen abgelegt werden und ggf. auch von Fahrzeug zu Fahrzeug weitergegeben werden.The evaluation of the sensor data, the on-board and the received sensor data is included otherwise received and stored traffic-relevant Information made. Such other traffic information can for example via a traffic radio channel received by a car radio and stored in a memory for current traffic reports and if necessary also passed from vehicle to vehicle.
Ein insbesondere für die Durchführung des Verfahrens nach Anspruch 1 geeignetes Verkehrswarngerät ist in Anspruch 2 beschrieben.A particularly for the implementation of the method according to claim 1 suitable traffic warning device is described in claim 2.
Weiterhin hat das erfindungsgemäße Verkehrswarngerät eine Empfangseinrichtung zum Empfang von von anderen Kraftfahrzeugen ausgesandten Sensordaten, die durch die Auswertungseinrichtung zur Bildung von Warnhinweisen vorzugsweise in Verbindung mit den bordeigenen Sensordaten ausgewertet werden. Zweckmäßigerweise ist die Empfangseinrichtung zugleich als Sendeeinrichtung zum Aussenden eigener Sensordaten an andere Fahrzeuge eingerichtet.Furthermore, the traffic warning device according to the invention a receiving device for receiving other motor vehicles emitted sensor data by the Evaluation device for forming warning notices preferably evaluated in connection with the on-board sensor data become. The receiving device is expedient at the same time as a sending device for sending your own sensor data to other vehicles.
Das Verkehrswarngerät weist ferner eine an die Auswertungseinrichtung angeschlossene Empfangseinrichtung für verkehrsrelevante Meldungen in mathematisch auswertbarer Form auf, beispielsweise durch den Empfang von im Rundfunk übertragenen Verkehrsmeldungen über einen separaten Verkehrsfunkkanal, die vorzugsweise in einem bekannten Protokoll, beispielsweise dem Alert-C-Protokoll ausgesandt werden und dem- gemäß im Empfänger auswertbar sind. The traffic warning device also has one Evaluation device connected receiving device for traffic-relevant messages in a mathematically evaluable form on, for example, by receiving broadcasts Traffic reports via a separate traffic radio channel, which are preferably in a known protocol, for example sent out according to the Alert-C protocol and accordingly can be evaluated in the receiver.
Es ist ohne weiteres klar, daß bei einem Datenaustausch von Sensordaten von Fahrzeug zu Fahrzeug oder der Verwendung anderweitiger Verkehrsinformationen eine Information über den Ort, auf den sich die Verkehrsinformation bzw. die Sensordaten beziehen, implizit oder explizit übermittelt werden muß. Wird eine Fahrzeug-Fahrzeug-Kommunikation nur mit einer kurzen Reichweite realisiert, ist die Ortsangabe möglicherweise entbehrlich. Im übrigen wird es zweckmäßig sein, eine Positionsangabe im Kraftfahrzeug zu generieren, beispielsweise durch eine satellitgestützte Positionsbestimmung, wie sie insbesondere in Kraftfahrzeug-Ortungssystemen enthalten ist. Vorzugsweise wird die Ortsangabe in einem Lokalisationscode, wie er im Alert-C-Protokoll vorgesehen ist, übertragen und ist dann mit den entsprechenden Lokalisationscodes in den Rundfunk-Verkehrsmeldungen vergleichbar.It is immediately clear that when exchanging data from Vehicle-to-vehicle sensor data or use elsewhere Traffic information an information about the Location to which the traffic information or sensor data refers relate, must be transmitted implicitly or explicitly. Becomes vehicle-to-vehicle communication only with a short Realized range, the location may not be necessary. For the rest, it will be useful to provide a position to generate in the motor vehicle, for example by a satellite-based position determination, such as in particular is contained in motor vehicle location systems. Preferably the location is in a localization code like it is provided in the Alert-C protocol, transferred and then with the corresponding localization codes in the broadcast traffic reports comparable.
Die Ausgabe der Warnhinweise kann optisch und/oder akustisch, aber auch haptisch, beispielsweise in Form von Vibrationen des Lenkrads, ausgegeben werden.The warnings can be output visually and / or acoustically, but also tactile, for example in the form of vibrations of the Steering wheel, are issued.
Die Erfindung soll im folgenden anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert werden.The invention is based on one in the drawing schematically illustrated embodiment explained in more detail become.
Gemäß der einzigen Figur gelangen Ausgangssignale von N-Sensoren
1 auf ein Schnittstellengerät 2, das ferner an einen
Kraftfahrzeugbus 3 angeschlossen ist, auf dem ein Datenaustausch
zwischen Aktoren und Sensoren des Kraftfahrzeugs stattfindet
und auf dem demzufolge auch für die Verkehrslage relevante
Informationen übertragen werden können, die von dem
Schnittstellengerät 2 erfaßt werden. Zusätzliche Informationen
4 können beispielsweise aus einem GPS-Modul für die Positionsbestimmung
sein. Die in das Schnittstellengerät 2 eingespeisten
Sensordaten und Informationen gelangen auf eine Auswertungsstufe
5, die mit vorgegebenen Algorithmen die Sensordaten
der Sensoren 1 und die sonstigen Informationen aus 3 und 4
auswertet und hieraus Warnhinweise geriert, die in einer Ausgabeeinrichtung
6 akustisch mit einem Lautsprecher 7 und/oder
optisch mit einer Anzeigeeinrichtung 8 ausgegeben werden.According to the single figure, output signals come from
Über eine Antenne 9 und eine Empfangseinrichtung 10, die zugleich
auch als Sendeeinrichtung dient, werden Sensordaten
anderer Fahrzeuge empfangen und der Auswertungseinrichtung 5
zugeleitet. Die empfangenen Sensordaten und sonstige empfangene
Informationen 4 können in einem Speicher 11 abgelegt und
dann zur weiteren Auswertung verwendet werden. Die zusätzlichen
Informationen 4 können über eine eigene Antenne oder
auch über die Antenne 9 empfangen werden, wenn diese als "Multisignal"-Antenne
ausgebildet ist.Via an
Ein Beispiel für eine Auswertung und Generierung
einer Warnmeldung mit Hilfe der Sensordaten der bordeigenen
Sensoren 1 kann sich daraus ergeben, daß die Sensorsignale
eines Außentemperatursensors, eines Regen-/Feuchtigkeitssensors
und eines Antriebsschlupfsensors ergeben, daß die Außentemperatur
unter 0° C liegt, daß es regnet und daß ein Antriebsschlupf
auftritt. Hieraus kann das Warnsignal abgeleitet
werden, daß Straßenglätte vorliegt.An example of an evaluation and generation
a warning message using the sensor data of the on-
Eine Verknüpfung von Sensordaten eines vorausfahrenden Fahrzeugs und von bordeigenen Sensordaten ermöglicht einen Warnhinweis beispielsweise im folgenden Fall:A combination of sensor data from a vehicle in front and on-board sensor data enables a warning for example in the following case:
Ein vorausfahrendes Fahrzeug befindet sich an einem Ort A und meldet die Sensordaten über Niederschlag, Temperatur, Uhrzeit usw.A vehicle in front is at location A and reports the sensor data about precipitation, temperature, time etc.
Das eigene Fahrzeug bewegt sich zu einem späteren Punkt auf
den Ort A zu und detektiert am eigenen Temperatursensor einen
Abfall der Temperatur auf den Gefrierpunkt. Die Auswertungseinrichtung
5 kann unter Verwendung der abgespeicherten Informationen
über den Ort A und die eigenen Sensordaten bei Annäherung
an den Ort A die Warnmeldung "Gefahr von Straßenglätte"
ausgeben. Your own vehicle moves to a later point
the location A and detects one at its own temperature sensor
Drop in temperature to freezing. The
Die eigenen Sensordaten können wiederum auf andere Fahrzeuge übermittelt werden, so daß diese ebenfalls eine Warnmeldung produzieren können. Einfacher kann es jedoch sein, die bereits ausgewertete Warnmeldung unmittelbar zu übertragen, und zwar entweder von Fahrzeug zu Fahrzeug oder von dem Fahrzeug zu einer Zentrale, die entsprechende Warnhinweise an die an sie angeschlossenen Verkehrsteilnehmer ausgibt, beispielsweise ein als Zentrale fungierender Service Provider an die Teilnehmer an einem Mobilfunknetz.Your own sensor data can in turn be transferred to other vehicles are transmitted so that this is also a warning can produce. However, it can be easier that already to transmit the evaluated warning message immediately either from vehicle to vehicle or from vehicle to a control center, the appropriate warnings to the to them outputs connected road users, for example Service provider acting as the central to the participants on a cellular network.
Insbesondere Wetterdaten, aber auch Informationen über bereits
bestehende Verkehrsbehinderungen können vorzugsweise als sonstige
Informationen 4 empfangenen werden und in dem Speicher
11 abgelegt werden.In particular weather data, but also information about already
existing traffic obstructions can preferably be considered
Ein weiteres Beispiel für die Kombination von Sensordaten eines
vorausfahrenden Fahrzeugs mit eigenen Sensordaten ergibt
sich, wenn von einem vorausfahrenden Fahrzeug ein abruptes
Bremsmanöver gemeldet wird und die lokale Sensorauswertung
einen Antriebsschlupf und ggfs. durch Auswertung eines Tachosensors
eine hohe Geschwindigkeit feststellt. In diesem Fall
wird als Warnhinweis durch die Ausgabevorrichtung 6 die
Empfehlung einer Geschwindigkeitsreduzierung ausgegeben.Another example of the combination of sensor data one
vehicle in front with their own sensor data
itself when an abrupt from a vehicle in front
Braking maneuvers are reported and the local sensor evaluation
a drive slip and possibly by evaluating a speedometer sensor
detects a high speed. In this case
is issued as a warning by the
Die genannten Beispiele zeigen, daß Gefahrenmeldungen ohne
Zeitverzögerung im Fahrzeug generiert und dem Fahrer ausgegeben
werden. Dabei kann die Verknüpfung akuter Informationen
durch die lokalen Sensordaten mit einem vorher im Speicher 11
abgespeicherten Wissen erfolgen und aus der Kombination neue
Meldungen generiert werden, die dem Fahrer ausgegeben und
ggfs. auf andere Fahrzeuge oder eine Zentrale übertragen werden,
damit schnelle Warnhinweise auch den anderen Verkehrsteilnehmern
zur Verfügung stehen.The examples mentioned show that hazard reports without
