Description
Die Erfindung betrifft eine neuartige Verwendung eines Informationsnetzes, mit dem Daten zwischen einzelnen Fahrzeugen in einer lokal begrenzten Umgebung übertragen werden können.The invention relates to a novel use of an information network, with the Transfer data between individual vehicles in a localized environment can be.
Derartige Informationsnetze sind aktuell in der Entwicklung, um eine Kommunikation bzw. einen Datenaustausch zwischen mobilen Stationen, insbesondere zwischen Fahrzeugen, zu ermöglichen. Dabei sollten in erster Linie die einzelne Fahrzeuge betreffende Zustandsdaten, wie z.B. die Fahrzeugposition und -geschwindigkeit, die Fahrtrichtung und die geplante Fahrtroute, übertragen werden aber auch situationsbezogene Daten, wie z.B. das Auftreten eines Staus oder die aktuelle Parkplatzsituation an bestimmten Standorten. Zudem wurde vorgeschlagen, derartige Informationsnetze zur Übertragung von Notrufsignalen beispielsweise im Falle eines Unfalls zu nutzen.Such information networks are currently under development to provide communication or a data exchange between mobile stations, in particular between Vehicles, to enable. It should primarily the individual vehicles status data concerning, e.g. the vehicle position and speed, the Driving direction and the planned route, but also be transferred situational data, such as the appearance of a traffic jam or the current one Parking situation at certain locations. It has also been suggested that such Information networks for the transmission of emergency signals, for example in the case of Accident to use.
Die Verwicklung in einen Unfall ist in der Regel auf eigenes Fehlverhalten oder auf das Fehlverhalten eines anderen Verkehrsteilnehmers zurückzuführen. Moderne Fahrerassistenzsysteme versuchen, dieses Risiko durch gezielte Unterstützung des Fahrers zu reduzieren. In diesem Zusammenhang wurde bereits vorgeschlagen, bestimmte Aspekte des Fahrerzustands, wie z.B. dessen Müdigkeit, Aufmerksamkeit, Beanspruchung, Emotionen, etc. als kritische Parameter bei der Aktivierung und sogar bei der funktionalen Ausgestaltung eines Fahrerassistenzsystems zu berücksichtigen. Involvement in an accident is usually due to one's own wrongdoing or that Attributed to misconduct by another road user. modern Driver assistance systems try to mitigate this risk by providing targeted support To reduce the driver. In this context, it has already been proposed to certain Aspects of the driver's condition, such as whose tiredness, attention, Stress, emotions, etc. as critical parameters in activation and even to be considered in the functional design of a driver assistance system.
Damit kann dem Fahrer beispielsweise auch sein eigenes mangelhaftes Reaktionsvermögen signalisiert werden. Derartige Fahrerassistenzsysteme können zwar das Risiko für ein Fehlverhalten des Fahrers eines entsprechend ausgestatteten Fahrzeugs verringern, wirken sich aber nicht auf das Fahrverhalten der übrigen Verkehrsteilnehmer aus.This can be the driver's own fault, for example Reactivity be signaled. Although such driver assistance systems can the risk of misconduct by the driver of a suitably equipped vehicle reduce, but do not affect the driving behavior of other road users out.
Erfindungsgemäß ist erkannt worden, dass sich das Unfallrisiko wesentlich verringern lässt, wenn das Fahrerassistenzsystem eines Fahrzeugs nicht nur über Zustandsdaten des eigenen Fahrers verfügt, sondern auch Zustandsdaten der in der Umgebung befmdlichen Fahrer berücksichtigen kann.According to the invention, it has been recognized that the accident risk is significantly reduced leaves when the driver assistance system of a vehicle not only on state data of the own driver, but also status data of those in the area Driver can consider.
Deshalb wird mit der vorliegenden Erfindung vorgeschlagen, ein Informationsnetz, mit dem Daten zwischen einzelnen Fahrzeugen in einer lokal begrenzten Umgebung übertragen werden können, zum Austausch von Fahrerzustandsinformationen zu nutzen. Erfindungsgemäß stellt ein solches Informationsnetz dann jedem Fahrzeug bzw. dessen Fahrer Informationen über den Zustand der übrigen Fahrer in einem lokal begrenzten Bereich zur Verfügung. Dadurch können potentielle Gefahrensituationen, die durch andere Fahrer bedingt werden, schneller und besser erkannt werden.Therefore, it is proposed with the present invention, an information network, with the data between individual vehicles in a localized environment can be used to exchange driver status information. According to the invention, such an information network then provides each vehicle or its Driver information about the condition of the remaining drivers in a localized Area available. This allows potential dangerous situations caused by other drivers are conditioned to be recognized faster and better.
In der Regel müssen die Fahrerzustandsinformationen, die auf unterschiedlichste Weise und mit den unterschiedlichsten Mitteln gewonnen werden können, dazu senderseitig aufbereitet werden. Einen weiteren Aspekt des erfindungsgemäßen Datenaustauschs bildet die Versendung und die u.U. gezielte Verteilung von Fahrerzustandsinformationen an andere Fahrzeuge. Schließlich müssen die übertragenen Daten auch empfängerseitig bereitgestellt bzw. aufbereitet werden.In general, the driver status information must be different in many ways and can be obtained with a variety of means, to the transmitter side be prepared. Another aspect of the data exchange according to the invention forms the dispatch and the u.U. Targeted distribution of driver status information to other vehicles. Finally, the transmitted data must also be the receiver side be prepared or prepared.
Der Fahrerzustand wird in der Regel durch mehrere Faktoren beeinflusst. So wird die Aufmerksamkeit des Fahrers beispielsweise nicht nur durch Müdigkeit beeinträchtigt, sondern auch wenn eine Beanspruchung durch weitere Fahrzeugsysteme, wie z.B. Telefon und Navigationssystem, vorliegt. Deshalb werden in einer vorteilhaften Variante der Erfindung Daten zu verschiedenen Aspekten des Fahrerzustands erfasst und auch ausgetauscht. Die Aussagekraft der sich daraus ergebenden Zustandsbeschreibung kann durch eine Bündelung der Informationen über einen defmierten Zeitraum, wie z.B. eine Mittelwertbildung oder auch die Angabe des in diesem Zeitraum ermittelten Minimaloder Maximalwerts, zusätzlich gesteigert werden. In diesem Zusammenhang erweist es sich als vorteilhaft, die gewonnenen Informationen zu den einzelnen Aspekten des Fahrerzustands senderseitig in ein einheitliches Datenformat zu transformieren.The driver's condition is usually influenced by several factors. So will the Driver's attention not only affected by fatigue, for example, but also when a load is imposed by other vehicle systems, such as e.g. Telephone and navigation system, is present. Therefore, in an advantageous variant The invention also collects data on various aspects of the driver's state and also replaced. The validity of the resulting description of the condition can by bundling the information over a defined period of time, e.g. a Averaging or the indication of the minimum or maximum determined during this period Maximum value, additionally increased. In this context, it proves prove to be beneficial to the information obtained on the individual aspects of Driver state sender side in a unified data format to transform.
In einer besonders vorteilhaften Variante der Erfindung werden die Fahrerzustandsinformationen mit weiteren Informationen über das Fahrzeug verbunden und zusammen mit diesen Fahrzeuginformationen über das Informationsnetz übertragen. Diese Fahrzeuginformationen können dann in vorteilhafter Weise ebenfalls vom Fahrerassistenzsystem ausgewertet werden, um Gefahrensituationen frühzeitig zu erkennen. So können beispielsweise zusammen mit den Fahrerzustandsinformationen Informationen über die aktuelle Position und Geschwindigkeit des Fahrzeugs, über die Fahrtrichtung und/oder die geplante Fahrzeugroute übermittelt werden. Anhand dieser Informationen, die beispielsweise mit Hilfe eines Navigationssystems ermittelbar sind, kann das Fahrerassistenzsystem eines empfangenden Fahrzeugs relativ zuverlässig abschätzen, ob eine Begegnung mit dem sendenden Fahrzeug bevorsteht und demzufolge das Fahrverhalten des Fahrers des sendenden Fahrzeugs zu berücksichtigen ist.In a particularly advantageous variant of the invention, the driver status information connected with more information about the vehicle and transmitted along with these vehicle information via the information network. This vehicle information can then also advantageously from Driver assistance system are evaluated to early risk situations detect. For example, together with the driver status information Information about the current position and speed of the vehicle over which Direction and / or the planned vehicle route are transmitted. Based on this Information which can be determined, for example, with the aid of a navigation system, the driver assistance system of a receiving vehicle can be relatively reliable estimate whether an encounter with the sending vehicle is imminent and consequently the driving behavior of the driver of the transmitting vehicle is to be considered.
Umgekehrt können anhand der von den einzelnen Fahrzeugen ausgesandten Fahrzeuginformationen auch die relevanten Empfängerfahrzeuge für ein sendendes Fahrzeug bestimmt werden, z.B. entgegenkommende Fahrzeuge und Fahrzeuge auf gleicher Fahrspur, mit gleicher Fahrtrichtung, etc.. In einer besonders vorteilhaften Variante der Erfindung werden die Fahrerzustandsinformationen dann auch nur diesen Empfängerfahrzeugen zur Verfügung gestellt. Eine angemessene Verteilung bzw. Versendung der Fahrerzustandsinformationen kann beispielsweise durch Begrenzung der Reichweite bzw. Leistung der Informationsübertragung gewährleistet werden, so dass nur Empfänger in der unmittelbaren Nähe des Senders die gesendeten Informationen empfangen können. Auf der Basis dieser Fahrzeugdaten können die für ein sendendes Fahrzeug relevanten Empfängerfahrzeuge bestimmt werden.Conversely, on the basis of the emitted by the individual vehicles Vehicle information also the relevant receiver vehicles for a sending Vehicle can be determined, e.g. oncoming vehicles and vehicles same lane, with the same direction of travel, etc .. In a particularly advantageous Variant of the invention, the driver state information then only this Receiver vehicles provided. An appropriate distribution or Dispatching the driver status information can, for example, by limiting the Range and performance of the information transmission are guaranteed, so that only Receiver in the immediate vicinity of the sender the information sent can receive. On the basis of these vehicle data, those for a sending Vehicle relevant receiver vehicles are determined.
Die Fahrerzustandsinformationen können direkt zwischen den Fahrzeugen ausgetauscht werden. Alternativ dazu kann die Informationsübertragung auch über eine Relais-Serverstation erfolgen. Dies erweist sich insbesondere dann als vorteilhaft, wenn die Fahrerzustandsinformationen gezielt nur an als relevant bestimmte Empfängerfahrzeuge verteilt werden soll. Die Relais-Serverstation wertet die von den einzelnen Fahrzeugen permanent oder zeitlich getaktet ausgesandten Informationen über ihre Position, Geschwindigkeit, Fahrtrichtung, etc. dann zentral aus und ermittelt so jeweils die Adressaten für die empfangenen Fahrerzustandsinformationen. Beispielsweise durch eine geeignete Codierung können diese Fahrerzustandsinformationen dann gezielt nur den relevanten Empfängerfahrzeugen zur Verfügung gestellt werden.The driver status information can be exchanged directly between the vehicles become. Alternatively, the information transfer via a relay server station respectively. This proves to be particularly advantageous if the Driver status information targeted only to relevant recipient vehicles to be distributed. The relay server station evaluates those of the individual vehicles permanently or temporally clocked sent information about their position, Speed, direction of travel, etc. then centrally and thus determines the respective Addressees for the received driver status information. For example, by a suitable coding, this driver state information can then target only the relevant recipient vehicles are made available.
Auch wenn die Fahrerzustandsinformationen nur ausgewählten, als relevant bestimmten Empfängerfahrzeugen zur Verfügung gestellt werden, sollte empfängerseitig zunächst geprüft werden, ob diese Informationen für das Empfängerfahrzeug in der aktuellen Fahrsituation relevant sind. Dazu müssen die empfangenen Fahrerzustandsinformationen empfängerseitig bereitgestellt werden, d. h. für das entsprechende System des Empfängerfahrzeugs aufbereitet werden. Hierzu kann die Extraktion der Fahrerzustandsinformationen von den sonstigen empfangenen Informationen gehören sowie die Transformation der empfangenen Datenformate in die notwendigen Formate bezogen auf das eigene System. Erst dann können die empfangenen Fahrerzustandsinformationen ausgewertet werden.Even if the driver state information only selected, determined as relevant Receiver vehicles should be provided at the receiver side first be checked if this information for the recipient vehicle in the current Driving situation are relevant. This requires the received driver status information be provided on the receiver side, d. H. for the corresponding system of Receiver vehicle are processed. For this purpose, the extraction of the Driver status information from the other received information as well as the transformation of the received data formats into the necessary formats based on your own system. Only then can the received Driver status information to be evaluated.
Wie bereits voranstehend erörtert, gibt es verschiedene Möglichkeiten, die Lehre der vorliegenden Erfindung in vorteilhafter Weise auszugestalten und weiterzubilden. Dazu wird einerseits auf die dem Patentanspruch 1 nachgeordneten Patentansprüche und andererseits auf die nachfolgende Beschreibung eines Ausführungsbeispiels der Erfindung anhand der Zeichnung verwiesen.As already discussed above, there are various ways of teaching present invention advantageously and further develop. To on the one hand to the claims subordinate to claim 1 and on the other hand, to the following description of an embodiment of the Reference directed to the invention with reference to the drawing.
Die einzige Figur zeigt ein Blockdiagramm zur Veranschaulichung des Austausch von Fahrerzustandsinformationen zwischen zwei Fahrzeugen in einer lokal begrenzten Umgebung.The single FIGURE is a block diagram illustrating the replacement of Driver status information between two vehicles in a localized Surroundings.
Jeder der beiden in der einzigen Figur dargestellten Blöcke 10 und 20 repräsentiert ein
Fahrzeug in einer lokal begrenzten Umgebung, wobei die Fahrzeuge 10 und 20 als mobile
Sende- und Empfangsstationen eines Informationsnetzes fungieren, mit dem Daten
zwischen den einzelnen Stationen übertragen werden können.Each of the two

der Regel stationär angeordnet ist aber auch mobil sein kann.The information network shown here further comprises a
Erfindungsgemäß wird das hier dargestellte Informationsnetz zum Austausch von Fahrerzustandsinformationen genutzt. Das Blockdiagramm der einzigen Figur soll die dafür erforderlichen Maßnahmen veranschaulichen.According to the invention, the information network shown here is for exchanging Driver state information used. The block diagram of the single figure is intended to be illustrate the necessary measures.
In beiden Fahrzeugen 10 und 20 werden Informationen 1 zu verschiedenen Aspekten des
Fahrerzustands erfasst. Diese Erfassung von biometrischen Daten kann mit den
unterschiedlichsten technischen Mitteln erfolgen, wie z.B. durch Messung der
Muskelaktivität oder des Hautwiderstands des Fahrers. Bestimmte Aspekte des
Fahrerzustands, wie z.B. seine Beanspruchung, lassen sich auch aus bestimmten
Fahrzeugdaten, wie z.B. der aktuellen Fahrzeuggeschwindigkeit und/oder der Aktivierung
weitere Systeme im Fahrzeug, wie der Telefonfreisprechanlage oder des
Navigationssystems, ableiten.In both
Im hier erläuterten Ausführungsbeispiel werden diese Fahrerzustandsinformationen durch
zusätzliche fahrzeugbezogene Informationen 2 ergänzt. Dabei kann es sich um die
technischen Daten des Fahrzeugs handeln und auch um aktuell erfasste
Fahrzeuginformationen, wie z.B. die Fahrzeugposition und -geschwindigkeit.In the exemplary embodiment explained here, this driver status information is transmitted through
additional vehicle-
Sowohl die Fahrerzustandsinformationen 1 als auch die zusätzlichen Informationen 2
werden einer Infortnationsaufbereitung 3 zugeführt, wo sie in ein einheitliches
Datenformat transformiert werden. Hier können auch verschiedene Aspekte des
Fahrerzustands über einen definierten Zeitraum zusammengefasst und ggf. klassifiziert
werden.Both the
Die so aufgearbeiteten Informationen können dann versendet werden, wozu die beiden
Fahrzeuge 10 und 20 mit einer entsprechenden Sendeeinrichtung 4 ausgestattet sind. Im
hier dargestellten Ausführungsbeispiel werden die Informationen der beiden Fahrzeuge
10 und 20 direkt zu dem jeweils anderen Fahrzeug 20 und 10 übertragen, was durch die
Pfeile 11 und 21 angedeutet wird. Außerdem werden die Informationen der beiden
Fahrzeuge 10 und 20 jeweils noch an die Relais-Serverstation 30 übertragen, was durch
die Pfeile 12 und 22 veranschaulicht wird.The processed information can then be sent, including the two
Die Relais-Serverstation verteilt die empfangenen Informationen dann an die jeweiligen
Adressaten, was mit Hilfe der Pfeile 31 und 32 dargestellt ist. Umfasst das
Informationsnetz mehr als nur zwei Fahrzeuge, d.h. befinden sich mehr als nur zwei
Fahrzeuge in einem lokal begrenzten Bereich, so können die relevanten Adressaten für
die von einem Fahrzeug ausgesandten Informationen anhand der von den übrigen
Fahrzeugen ausgesandten Fahrzeuginformationen, wie aktuelle Fahrzeugposition, -
geschwindigkeit und -richtung bestimmt, werden. Die Relais-Serverstation 30 kann dann
die von einem Fahrzeug empfangenen Informationen gezielt nur an bestimmte Fahrzeuge
weiterleiten, beispielsweise nur an Fahrzeuge, die sich auf derselben Fahrbahn befinden,
wie das sendende Fahrzeug.The relay server station then distributes the received information to the respective one
Addressees, which is shown with the aid of
Die beiden Fahrzeuge 10 und 20 verfügen außerdem jeweils über eine Empfangseinrichtung
6 zum Empfang der von anderen Fahrzeugen ausgesandten Informationen.
Die empfangenen Informationen werden einer Informationsbearbeitung 7
zugeführt, wo sie beispielsweise in ein für das System des empfangenden Fahrzeugs
geeignetes Datenformat transformiert werden können. Außerdem können hier die im
System des empfangenden Fahrzeugs auswertbaren Daten extrahiert und ausgewertet
werden. Dabei werden auch die empfangenen Fahrerzustandsinformationen ausgewertet.
Das Ergebnis dieser Informationsbearbeitung 7 wird dann bei 8 bereitgestellt. Im hier
dargestellten Ausführungsbeispiel werden die empfangenen Fahrerzustandsinformationen
mit den Informationen 1 über den Zustand des eigenen Fahrers verknüpft, was durch die
Pfeile 13 und 23 angedeutet ist.The two
Wie das voranstehend beschriebene Ausführungsbeispiel veranschaulicht, handelt es sich bei der Erfindung um die generelle Aufarbeitung, Verteilung und Versendung sowie den Empfang, die Bearbeitung und Bereitstellung von Informationen zu allen Ausprägungen des Fahrerzustandes, so dass möglichst jedem Fahrzeug in einem lokal begrenzten Bereich jederzeit Informationen zum Fahrerzustand der jeweils relevanten anderen Fahrzeuge in diesem Bereich zur Verfügung stehen. Dadurch können potentielle, durch andere Fahrer verursachte Gefahrensituationen schneller und besser erkannt werden. Die erfindungsgemäß zur Verfügung gestellten Fahrerzustandsinformationen anderer Fahrzeuge können dazu genutzt werden, den Fahrer des empfangenden Fahrzeugs explizit vor konkreten Gefahren zu warnen. Beispielsweise kann ein Fahrer, der sich einer Kreuzung nähert, frühzeitig vor einem Fahrzeug gewarnt werden, das sich ebenfalls dieser Kreuzung aus einer anderen Richtung nähert, wenn dessen Fahrer besonders unaufmerksam ist. Die empfangenen Fahrerzustandsinformationen können aber auch vom Fahrerassistenzsystem des empfangenden Fahrzeugs ausgewertet werden, um beispielsweise die Müdigkeit des Fahrers des vorausfahrenden Fahrzeugs beim automatischen Auslösen von Präventivmaßnahmen zu berücksichtigen. So könnte das ACC hier beispielsweise automatisch eine größere Zeitlücke wählen.As the embodiment described above illustrates, it is in the invention to the general workup, distribution and shipping and the Reception, processing and provision of information on all forms the driver's condition, allowing as much as possible each vehicle in a localized Area at any time information on the driver status of the relevant other Vehicles in this area will be available. This allows potential, through other drivers caused dangerous situations to be detected faster and better. The According to the invention provided driver state information of others Vehicles can be used to explicitly identify the driver of the receiving vehicle to warn of concrete dangers. For example, a driver who is one Approaching intersection, be warned in advance of a vehicle that is also approaching this intersection from another direction, if its driver is particularly inattentive is. The received driver status information can also be from the Driver assistance system of the receiving vehicle to be evaluated For example, the fatigue of the driver of the preceding vehicle when automatic triggering of preventive measures. So that could be For example, ACC automatically selects a larger time gap here.
