Vor diesem Hintergrund werden ein Verfahren, eine Vorrichtung und eine Anordnung mit den Merkmalen der unabhängigen Patentansprüche vorgestellt. Weitere Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Patentansprüchen und der Beschreibung.Against this background, a method, a device and an arrangement with the features of the independent claims are presented. Further embodiments of the invention will become apparent from the dependent claims and the description.

Mit der Erfindung kann u. a. eine Manövrierassistenz für lange und/oder überbreite Fahrzeuge bereitgestellt werden. Andere Verkehrsteilnehmer, üblicherweise Fahrzeuge, werden unter Einsatz einer Kommunikation zwischen Fahrzeugen (C2C- bzw. Car-to-Car-Communication) auf eine bestimmte Verkehrssituation vorausschauend hingewiesen und so vor dieser Verkehrssituation gewarnt. Da somit mindestens einem anderen, zweiten Fahrzeug bekannt ist, welche Fläche ein erstes Fahrzeug in nächster Zukunft befährt, kann auf eine ggf. gefährliche Verkehrssituation durch geeignete Reaktion vorab reagiert und somit bspw. eine Kollision zwischen Fahrzeugen vermieden werden. Mit der Erfindung kann u. a. ein Assistenzsystem, das die Fahrer typischerweise langer und/oder überbreiter Fahrzeuge beim Befahren in der Regel enger Kurven unterstützt, realisiert werden.With the invention can u. a. a maneuvering assistance for long and / or oversized vehicles are provided. Other road users, usually vehicles, are foresighted by using communication between vehicles (C2C or car-to-car communication) to a specific traffic situation and thus warned about this traffic situation. Since at least one other, second vehicle knows which surface a first vehicle is traveling in the near future, it is possible to react in advance to a possibly dangerous traffic situation by means of a suitable reaction and thus, for example, avoid a collision between vehicles. With the invention can u. a. an assistance system, which supports the drivers of typically long and / or extra-wide vehicles when driving usually tight curves, can be realized.

Das Verfahren ermöglicht bspw. eine Unterstützung des Fahrers eines langen und/oder überbreiten Fahrzeugs in schwierigen Situationen. Andere Verkehrsteilnehmer, die bereitwillig Hilfe geben, werden dazu bestärkt und bei Durchführung des Verfahrens dabei unterstützt, dies sinnvoll zu tun. Außerdem kann eine Optimierung des globalen Verkehrsflusses ermöglicht werden. Das kurze Warten weniger Verkehrsteilnehmer reduziert die Gesamtwartezeit. Somit können Versperrungssituationen und Begegnungsunfälle vermieden sowie Konfliktsituationen entschärft werden.The method makes it possible, for example, to assist the driver of a long and / or over-width vehicle in difficult situations. Other road users who willingly give help are encouraged and assisted in making the process meaningful. In addition, an optimization of the global traffic flow can be made possible. The short wait for less traffic reduces the total waiting time. Thus, obstruction situations and encounters accidents can be avoided and conflict situations can be defused.

Bei einer Fahrzeug-Fahrzeug-Kommunikation (C2C) kann anderen, zweiten Fahrzeugen mitgeteilt und/oder angezeigt werden, an welchem Ort das erste, üblicherweise lange und/oder überbreite Fahrzeug eine Fläche einer bestimmten Abmessung zu einem Zeitpunkt benötigt, um bestimmte Manöver durchzuführen. Die anderen Verkehrsteilnehmer werden gebeten, diese Flächen freizuhalten.In a vehicle-to-vehicle communication (C2C), other, second vehicles may be notified and / or displayed at which location the first, usually long and / or oversized vehicle occupies an area of a particular one Dimension needed at a time to perform certain maneuvers. The other road users are asked to keep these areas clear.

Oft reicht die Schleppkurve bzw. Traktrix von typischerweise langen und/oder überbreiten Fahrzeugen in eine weitere Fahrspur, wie bspw. eine Gegenfahrspur hinein, was regelmäßig in engen Kurven der Fall ist. Die Erfindung schlägt hierzu u. a. ein Assistenzsystem vor, das solche Flächen aus der Fahrzeuggeometrie und z. B. aus Karteninformationen bestimmt. Die Schleppkurve kann die von dem ersten Fahrzeug in nächster Zukunft befahrene Fläche zumindest teilweise, in der Regel vollständig umfassen.Often the towing curve or Traktrix of typically long and / or overwidth vehicles extends into another lane, such as an opposite lane, which is the case regularly in tight turns. The invention proposes this u. a. an assistance system that such areas from the vehicle geometry and z. B. determined from map information. The towing curve may at least partially, as a rule, completely cover the area occupied by the first vehicle in the near future.

Die vom ersten Fahrzeug benötigte Fläche kann im Rahmen der Erfindung bspw. durch Berechnung bestimmt werden. Aus dieser Fläche kann weiterhin eine Konfliktfläche abgeleitet werden. Diese Konfliktfläche umfasst jenen Anteil der Fläche, der sich auf einer Fahrbahn außerhalb der Fahrbahn des ersten Fahrzeugs und/oder auf einer Fahrbahn des mindestens einen zweiten Fahrzeugs befindet.The area required by the first vehicle can be determined by calculation within the scope of the invention, for example. From this area, a conflict area can still be derived. This conflict area comprises that portion of the area which is located on a lane outside the lane of the first vehicle and / or on a lane of the at least one second vehicle.

Informationen darüber, zu welchem Zeitpunkt sich die bei der Weiterfahrt des ersten Fahrzeugs ggf. dynamisch verändernde Fläche befindet und welche Abmessungen sie aufweist, kann z. B. durch Car-to-Car bzw. C2C-Kommunikation anderen Fahrzeugen mitgeteilt werden. Die übermittelten Informationen können über Empfangsmodule von dem anderen, zweiten Fahrzeug empfangen und weiterverarbeitet werden. Über eine geeignete Mensch-Maschine-Schnittstelle (Human-Machine-Interface, HMI) kann einem Fahrer des mindestens einen zweiten Fahrzeugs optisch und/oder akustisch zumindest ein Hinweis auf die Fläche angezeigt werden, falls die Fläche auf seiner Fahrtroute liegt. Die Konfliktfläche kann dem Fahrer optisch angezeigt werden, zudem ist es bspw. möglich, den Fahrer über akustische Anweisungen zu bitten, an einer bestimmten Stelle anzuhalten, um die von dem ersten Fahrzeug zu befahrende Fläche freizulassen.Information about the time at which the further dynamically changing surface during the further travel of the first vehicle and which dimensions it has can, for. B. be communicated to other vehicles by car-to-car or C2C communication. The transmitted information can be received via receiving modules from the other, second vehicle and further processed. Via a suitable human-machine interface (HMI), a driver of the at least one second vehicle can be visually and / or acoustically displayed at least an indication of the area if the area lies on his travel route. The conflict surface can be visually displayed to the driver, and it is also possible, for example, to ask the driver via acoustic instructions to stop at a certain point in order to release the area to be traveled by the first vehicle.

Die anderen zweiten Fahrzeuge können dann dazu aufgefordert werden, diese Fläche freizuhalten, um das lange und/oder überbreite Fahrzeug vorbeizulassen. Alternativ kann bei entsprechender Verkehrssituation das lange und/oder überbreite Fahrzeug aufgefordert werden, zu halten, bis die Fläche frei ist.The other second vehicles may then be prompted to keep this area clear to let the long and / or oversized vehicle pass. Alternatively, in case of appropriate traffic situation, the long and / or oversized vehicle may be requested to hold until the area is clear.

Die Figuren werden zusammenhängend und übergreifend beschrieben, gleiche Bezugszeichen bezeichnen gleiche Komponenten.The figures are described in a coherent and comprehensive manner, like reference numerals designate like components.

Die Figuren 1 und 2 zeigen eine Verkehrssituation zu einem ersten Zeitpunkt (Figur 1) und einen zweiten Zeitpunkt (Figur 2) in schematischer Darstellung. Hierbei ist vorgesehen, dass auf einer Straße 2 entlang einer Kurve 4 ein erstes Fahrzeug 6, das als ein Lastkraftwagen ausgebildet ist, an dem ein Anhänger 8 angehängt ist, sich entlang einer ersten Fahrspur 10 bewegt. Ein zweites Fahrzeug 12, das sich auf einer zweiten, entgegengesetzten Fahrbahn 14 bewegt, ist ebenfalls in die beschriebene Verkehrssituation eingebunden.The FIGS. 1 and 2 show a traffic situation at a first time ( FIG. 1 ) and a second time ( FIG. 2 ) in a schematic representation. in this connection It is provided that on a road 2 along a curve 4, a first vehicle 6, which is formed as a truck to which a trailer 8 is attached, moves along a first lane 10. A second vehicle 12, which moves on a second, opposite roadway 14, is also involved in the described traffic situation.

In der vorliegenden Ausführungsform der Erfindung weist das erste Fahrzeug 6 eine erste Ausführungsform einer erfindungsgemäßen Vorrichtung 19 auf, die ein Bestimmungsmodul 16, das ggf. mit Sensoren zusammenwirkt, sowie ein Kommunikationsmodul 18 umfasst. Dabei ist das Bestimmungsmodul 16 dazu ausgebildet, unter Berücksichtigung von Parametern, die sich aufgrund der gegebenen Verkehrssituation ergeben, bereits zu dem ersten Zeitpunkt (Figur 1) zu bestimmen, welche Fläche 20 von dem ersten Fahrzeug 6 inklusive Anhänger 8 in nächster Zukunft, d. h. zum zweiten Zeitpunkt (Figur 2), benötigt wird. Als Parameter zur Bestimmung dieser Fläche 20 werden eine Länge und Breite des ersten Fahrzeugs 6, eine Breite der Straße 2, üblicherweise eine Breite mindestens einer der beiden Fahrbahnen 10, 14, sowie eine Neigung und/oder Krümmung der Kurve 4 verwendet.In the present embodiment of the invention, the first vehicle 6 comprises a first embodiment of a device 19 according to the invention, which comprises a determination module 16, which optionally interacts with sensors, as well as a communication module 18. In this case, the determination module 16 is configured, taking into account parameters that arise on the basis of the given traffic situation, already at the first time point (FIG. FIG. 1 ) determine which area 20 of the first vehicle 6 including trailer 8 in the near future, ie at the second time ( FIG. 2 ) is needed. As a parameter for determining this surface 20, a length and width of the first vehicle 6, a width of the road 2, usually a width of at least one of the two lanes 10, 14, and a slope and / or curvature of the curve 4 are used.

Sobald Informationen über die Fläche 20 von dem Bestimmungsmodul 16 durch Berechnung bereitgestellt sind, werden diese ausgehend von dem Kommunikationsmodul 18 über eine Fahrzeug-Fahrzeug-Kommunikation 24 (C2C) dem zweiten Fahrzeug 12 bereitgestellt. Dabei wird das zweite Fahrzeug 12 üblicherweise darüber informiert, zu welchem Zeitpunkt sich die Fläche 20 an welcher Position der Straße 2 befindet. Weiterhin kann aus der Fläche 20 auch eine sog. Konfliktfläche abgeleitet werden, wobei die Konfliktfläche jener Anteil der bestimmten Fläche 20 ist, der sich außerhalb der Fahrbahn 10 des ersten Fahrzeugs 6 und/oder auf der Fahrbahn 14 des zweiten Fahrzeugs 12 befindet. Somit wird u. a. ermittelt, wo die Fläche 20 die zweite Fahrbahn 14, auf der sich das zweite Fahrzeug 12 befindet, überschneidet.Once information about the surface 20 is provided by the determination module 16 by calculation, it is provided to the second vehicle 12 from the communication module 18 via a vehicle-to-vehicle communication 24 (C2C). In this case, the second vehicle 12 is usually informed about the time at which the surface 20 is at which position of the road 2. Furthermore, from the surface 20, a so-called. Conflict surface can be derived, the conflict area is that proportion of the particular area 20, which is outside the lane 10 of the first vehicle 6 and / or on the lane 14 of the second vehicle 12. Thus u. a. determines where the surface 20 intersects the second lane 14 on which the second vehicle 12 is located.

In der beschriebenen Ausführungsform der Erfindung ist weiterhin vorgesehen, dass das zweite Fahrzeug 12 ein Kommunikationsmodul 26 aufweist, das dazu ausgebildet ist, die über die Fahrzeug-Fahrzeug-Kommunikation 24 in dem ersten Fahrzeug 6 bereitgestellten Informationen über die Fläche 20 zu empfangen. Diese empfangenen Informationen werden von einem in dem zweiten Fahrzeug 12 ebenfalls angeordneten Verarbeitungsmodul 28 verarbeitet, wobei aus den Informationen über die Fläche 20 die für das zweite Fahrzeug 12 relevante Konfliktfläche bestimmt werden kann. Das Fahrzeug-Fahrzeug-Kommunikationsmodul 24, das Verarbeitungsmodul 28 und die erste Ausführungsform der erfindungsgemäßen Vorrichtung 19 bilden eine erste Ausführungsform einer erfindungsgemäßen Anordnung 29.In the described embodiment of the invention it is further provided that the second vehicle 12 has a communication module 26 which is adapted to receive the information about the area 20 provided via the vehicle-vehicle communication 24 in the first vehicle 6. This received information is from one in the second vehicle 12 processing module 28 also arranged processed, wherein from the information about the surface 20, the relevant for the second vehicle 12 conflict area can be determined. The vehicle-vehicle communication module 24, the processing module 28 and the first embodiment of the device 19 according to the invention form a first embodiment of an arrangement 29 according to the invention.

Es ist vorgesehen, dass die Informationen über die Fläche 20 bereits zu dem ersten Zeitpunkt bestimmt und an das zweite Fahrzeug 12 weitergeleitet werden. Unter Berücksichtigung der empfangenen Informationen hält das zweite Fahrzeug 12 zu dem zweiten Zeitpunkt, in dem das erste Fahrzeug 6 die bestimmte Fläche 20 befährt, noch vor der Kurve 4 an. Dies wird bspw. dadurch ermöglicht, dass das Verarbeitungsmodul 28 den Fahrer des zweiten Fahrzeugs 12 auf die bevorstehende Verkehrssituation hinweist, so dass der Fahrer das zweite Fahrzeug 12 anhält. Ein Anhalten des zweiten Fahrzeugs 12 kann auch durch das Verarbeitungsmodul 28 kontrolliert erfolgen, wobei das Verarbeitungsmodul 28 eine Funktion von Lenkung und/oder Bremse des zweiten Fahrzeugs 12 automatisch beeinflusst.It is provided that the information about the surface 20 is already determined at the first time and forwarded to the second vehicle 12. Taking into account the received information, the second vehicle 12 stops before the curve 4 at the second point in time at which the first vehicle 6 travels the particular area 20. This is made possible, for example, by the processing module 28 indicating the driver of the second vehicle 12 of the imminent traffic situation, so that the driver stops the second vehicle 12. A stop of the second vehicle 12 may also be controlled by the processing module 28, wherein the processing module 28 automatically affects a function of steering and / or braking of the second vehicle 12.
