Description

Die Erfindung betrifft ein Verfahren zur Verhinderung des Fahrens entgegen der vorgeschriebenen Fahrtrichtung mit einem mit einer Satelliten-Positionsbestimmungs- und Navigationseinrichtung versehenen Fahrzeug, bei dem mit einer Erkennungseinrichtung im Fahrzeug in Fahrtrichtung befindliche Verkehrsschilder erkannt werden, die die Einfahrt verbieten, und im Anschluss an eine derartige Erkennung einer Falschfahrt im Fahrzeug ein Steuersignal zur Unterbindung des Weiterfahrens generiert wird, wenn die Fahrt fortgesetzt wird.The invention relates to a method for preventing driving against the prescribed direction of travel with a vehicle provided with a satellite positioning and navigation device, are detected in the vehicle with a detection device in the direction of travel signs that prohibit entry, and following a Such detection of a wrong drive in the vehicle, a control signal to prevent further driving is generated when the journey is continued.

Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung des Verfahrens.The invention further relates to a device for carrying out the method.

Das Problem des irrtümlichen Einfahrens in eine Fahrstraße entgegen der für diese Fahrstraße vorgesehenen Fahrtrichtung existiert insbesondere für Autobahnen und wir dort regelmäßig durch die Benutzung einer Ausfahrt als Einfahrt hervorgerufen. Im Normalfall wird die Benutzung einer Autobahn- oder Schnellstraßenausfahrt als Einfahrt dadurch verhindert, dass die Ausfahrtspur an ihrer Einmündung in eine normale Verkehrsstraße durch Verkehrsschilder gekennzeichnet wird, die die Einfahrt in die insoweit als Einbahnstraße dienende Ausfahrt verbieten. Die entsprechenden Verkehrsschilder findet man daher auch an Enden von Einbahnstraßen um die Einfahrt entgegen der vorgeschriebenen Fahrtrichtung zu untersagen. Insbesondere auf mehrspurigen Straßen und manchmal etwas unübersichtlich angelegten Einfahrten in eine Autobahn oder Schnellstraße, die unmittelbar der entsprechenden Ausfahrt benachbart sind, kommt es gelegentlich zu einer irrtümlichen Benutzung der falschen Fahrspur durch Verkehrsteilnehmer, die die Verkehrssituation an dieser Stelle nicht vollständig überblicken.The problem of erroneously entering a driveway contrary to the direction of travel provided for this driveway exists in particular for highways and we there regularly caused by the use of an exit as a driveway. Normally, the use of a highway or highway exit is prevented as entry by the exit lane is marked at its confluence with a normal traffic route by traffic signs that prohibit the entrance to the extent serving as a one-way exit. The corresponding traffic signs can therefore be found at the ends of one-way streets to prohibit the entrance contrary to the prescribed direction. In particular, on multi-lane roads and sometimes somewhat confusing entries into a highway or expressway, which are immediately adjacent to the corresponding exit, there is occasionally an erroneous use of the wrong Lane by road users who do not fully survey the traffic situation at this point.

Ein weiterer Grund für Falschfahrten resultiert aus einer gewollten Benutzung der falschen Fahrspur, um sich bewusst einem erheblichen Risiko auszusetzen und eine eigene Verletzung oder die Verletzung anderer Verkehrsteilnehmer in Kauf zu nehmen oder gar anzustreben.Another reason for wrong-way driving results from a deliberate use of the wrong lane in order to consciously expose yourself to a considerable risk and to accept or even strive for your own injury or injury to other road users.

Ein Verfahren der eingangs erwähnten Art ist durch DE 100 05 140 A1 bekannt. In nicht näher dargelegter Weise soll das Verkehrsschild "Einfahrt verboten" durch ein Erkennungssystem erkannt werden und zu einem akustischen Warnsignal führen. Dieses kann zunächst innerhalb des Fahrzeuges, bei einer Weiterfahrt auch außerhalb des Fahrzeuges ertönen und mit dem automatischen Einschalten einer Warnblinkanlage gekoppelt sein. Wenn auch danach eine Weiterfahrt noch erfolgt, soll das Fahrzeug über die Elektronik bis zum Stillstand abgebremst werden. Kriterien hierfür sind - außer einer allgemeinen Zielstellung - nicht angegeben.A method of the type mentioned is by DE 100 05 140 A1 known. In unspecified manner, the traffic sign "entrance prohibited" should be detected by a recognition system and lead to an audible warning signal. This can first be heard within the vehicle, in a further journey outside the vehicle and be coupled with the automatic switching on a hazard warning lights. If the vehicle continues to travel after this, the vehicle should be braked to a standstill via the electronics. Criteria for this are - except a general objective - not specified.

Die DE 198 29 374 A1 offenbart eine andere Lösung für das Problem der Falschfahrer, wobei das Verkehrsschild Signale aussendet, durch die das falsch fahrende Fahrzeug aufgrund einer Einwirkung auf die Zündung zum Stillstand gebracht wird. Diese Lösung setzt einen erheblichen Aufwand für die Bestückung der Verkehrsschilder einerseits und die Bestückung der Kraftfahrzeuge andererseits mit entsprechenden Geräten voraus.The DE 198 29 374 A1 discloses another solution to the problem of wrong-way drivers, wherein the traffic sign emits signals by which the wrong-traveling vehicle is brought to a standstill due to an effect on the ignition. This solution requires a considerable effort for the assembly of traffic signs on the one hand and the assembly of vehicles on the other hand with appropriate equipment.

Durch DE 199 54 002 A1 , DE 10 2004 042 382 A1 und DE 10 2007 005 245 A1 sind Erkennungseinrichtungen für Verkehrsschilder bekannt, die auf der Basis einer Auswertung eines Kamerabildes die Erfassung des Inhaltes von Verkehrsschildern ermöglichen. Der Schwerpunkt liegt dabei auf der Erkennung von Geschwindigkeitsbeschränkungen und die Einblendung entsprechender Informationen in ein für den Fahrer ablesbares Display.By DE 199 54 002 A1 . DE 10 2004 042 382 A1 and DE 10 2007 005 245 A1 Identification devices for traffic signs are known, which enable the detection of the content of traffic signs on the basis of an evaluation of a camera image. The focus is on the detection of speed limits and the display of appropriate information in a readable for the driver display.

Mit der DE 102 31 768 A1 wird vorgeschlagen, das Fahren entgegen der vorgeschriebenen Fahrtrichtung dadurch zu erkennen, dass ein Satelliten-Positionsbestimmungssystem verwendet wird, das in vielen Fahrzeugen enthalten ist. Das Positionsbestimmungssystem muss hierfür mit einer zutreffenden und aktuellen digitalen Karte ausgerüstet sein, um eine Fahrt in eine nicht zugelassene Fahrtrichtung zu erkennen. Wird eine Fahrt in die falsche Fahrtrichtung erkannt, soll das Fahrzeug stillgelegt werden.With the DE 102 31 768 A1 It is proposed to recognize driving contrary to the prescribed direction of travel by using a satellite positioning system included in many vehicles. The positioning system must be equipped with an appropriate and up-to-date digital map to detect a trip in an unauthorized direction. If a trip is detected in the wrong direction, the vehicle should be shut down.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein nach heutiger Technik einfach zu realisierendes System anzugeben, mit dem gewollte oder ungewollte Fahrten auf Straßen entgegen der vorgeschriebenen Fahrtrichtung zumindest zu einem großen Teil verhindert werden.The present invention has for its object to provide a simple to implement today's technology system with the intentional or unwanted driving on roads against the prescribed direction at least to a large extent prevented.

Zur Lösung dieser Aufgabe ist erfindungsgemäß ein Verfahren der eingangs erwähnten Art dadurch gekennzeichnet, dass nach der Erkennung der Falschfahrt mittels der Erkennungseinrichtung während der Weiterfahrt mit Hilfe der Satelliten-Positionsbestimmungs- und Navigationseinrichtung überprüft wird, ob die Weiterfahrt in die falsche Richtung erfolgt und dass in Abhängigkeit von dieser Überprüfung das Steuersignal zur Unterbindung des Weiterfahrens generiert wird.To solve this problem, a method of the type mentioned above is characterized in that is checked after detecting the wrong drive by means of the detection device during the onward journey using the satellite positioning and navigation device, whether the onward journey is in the wrong direction and that in Depending on this check the control signal is generated to prevent further driving.

Der vorliegenden Erfindung liegt die Erkenntnis zugrunde, dass ein großer Anteil der Fahrzeuge mit einer Satelliten-Positionsbestimmungs- und Navigationseinrichtung versehen sind, mit der die momentane Position des Fahrzeugs bereits auf wenige Meter genau bestimmt werden kann, beispielsweise über GPS (Global Positioning System). Da eine derartige Navigationseinrichtung digitale Karten enthält, die sowohl die Ausfahrt als auch die Einfahrt einer Autobahn oder Schnellstraße beinhaltet, kann grundsätzlich eine derartige Satelliten-Positionsbestimmungs- und Navigationseinrichtung dazu verwendet werden, Falschfahrten in einem relativ frühen Stadium zu erkennen. Der vorliegenden Erfindung liegt jedoch die Erkenntnis zugrunde, dass weder mit der Satelliten-Positionsbestimmungs- und Navigationseinrichtung noch mit der Verkehrsschilderfassung allein ein in der Praxis verantwortbarer Eingriff in das Fahrzeug nicht sinnvoll durchgeführt werden kann.The present invention is based on the finding that a large proportion of the vehicles are provided with a satellite positioning and navigation device with which the instantaneous position of the vehicle can already be determined accurately to a few meters, for example via GPS (Global Positioning System). In principle, since such a navigation device contains digital maps which include both the exit and the entrance of a freeway or expressway, such a satellite positioning and navigation device can be used to detect wrong journeys at a relatively early stage. However, the present invention is based on the finding that neither in the satellite position determination and navigation device nor with the traffic sign detection alone a responsible in practice responsible intervention in the vehicle can not be made meaningful.

Die Erkennung der Verkehrsschilder allein kann sinnvollerweise nicht zu einer Unterbindung der Weiterfahrt führen, wenn während der Weiterfahrt der Fehler dadurch korrigiert wird, dass von der ursprünglich benutzten Ausfahrtspur auf die richtigerweise zu benutzende Einfahrtspur gewechselt wird, beispielsweise durch ein in diesem Notfall tolerierbares Überfahren einer doppelt durchgezogenen Markierungslinie oder durch das Fahren über einen Grünstreifen.The recognition of the traffic signs alone can usefully not lead to a suppression of onward travel, if during the onward journey, the error is corrected by the fact that is changed from the originally used exit lane to the right to use entrance lane, for example by passing over a double continuous marking line or by driving over a green strip in a tolerable manner.

Die Steuerung mit der Satelliten-Positionsbestimmungs- und Navigationseinrichtung allein erscheint ebenfalls nicht praktikabel, weil gelegentlich beispielsweise Baustellenumleitung auch so geführt sein können, dass die Verkehrsführung gewollt und abgesichert auf einer Fahrbahn in einer Richtung erfolgt, die der sonst für diese Fahrbahn vorgesehenen Richtung entgegengerichtet ist. In diesem Fall darf das Fahrzeug naturgemäß nicht zwangsläufig angehalten werden. Wenn erfindungsgemäß zusätzlich eine Detektion eines die Einfahrt verbietenden Verkehrsschildes erforderlich ist, wird eine derartige Stillsetzung des Fahrzeuges vermieden, weil im Falle einer eingerichteten Umleitung die Verkehrsschilder entfernt oder abgedeckt werden.The control with the satellite positioning and navigation device alone also does not seem feasible, because occasionally, for example, site redirection can also be performed so that the traffic management will be deliberate and secured on a roadway in a direction opposite to the otherwise intended for this roadway direction , In this case, the vehicle must by its nature not necessarily be stopped. If, in accordance with the invention, detection of a traffic sign forbidding entry is additionally required, such a shutdown of the vehicle is avoided because in the case of an established detour the traffic signs are removed or covered.

Die erfindungsgemäße Verknüpfung der Erkennung der die Einfahrt verbietenden Verkehrsbeschilderung einerseits mit der Verifizierung der so eingeleiteten Falschfahrt beim Weiterfahren durch die Satelliten-Positionsbestimmungs- und Navigationseinrichtung andererseits ermöglicht erstmalig einen realistisch durchzuführenden Eingriff in die Fahrzeugelektronik zum Anhalten des Fahrzeugs, um eine Falschfahrt ("Geisterfahrt") in die falsche Fahrtrichtung zu verhindern.The inventive combination of the detection of prohibiting the entrance traffic signs on the one hand with the verification of the thus introduced wrong drive on driving through the satellite positioning and navigation device on the other hand allows the first realistic to be performed intervention in the vehicle electronics to stop the vehicle to a wrong drive ("ghost ride" ) in the wrong direction.

In einer bevorzugten Ausführungsform der Erfindung wird aus dem Fahrzeug heraus ein Warnsignal abgegeben, wenn die Falschfahrt erkannt worden ist. Dieses Warnsignal kann optisch oder akustisch erkennbar sein, ist vorzugsweise jedoch ein drahtlos übertragenes Signal, das von Empfängern in der Nähe des Fahrzeugs empfangen und erkannt werden kann. Insbesondere kann das Warnsignal über eine Kommunikation von Fahrzeug zu Fahrzeug auf in der Nähe befindliche Fahrzeuge übertragen werden. Alternativ oder ergänzend ist es möglich, das Warnsignal auf eine Notrufzentrale zu übermitteln, beispielsweise durch eine Mobilfunkverbindung.In a preferred embodiment of the invention, a warning signal is emitted from the vehicle when the wrong drive has been detected. This warning signal can be visually or audibly recognizable, but is preferably a wirelessly transmitted signal that can be received and detected by receivers in the vicinity of the vehicle. In particular, the warning signal can be transmitted via a vehicle-to-vehicle communication to nearby vehicles. Alternatively or additionally, it is possible to transmit the warning signal to an emergency call center, for example by a mobile radio connection.

Die Übermittlung des Warnsignals kann auch auf eine stationäre Kommunikationseinrichtung erfolgen, durch die Warneinrichtungen gesteuert werden können. So ist es beispielsweise möglich, an besonders gefährdeten Stellen eine stationäre Bake vorzusehen, die derartige Warnsignale empfangen und beispielsweise elektronische Verkehrsbeeinflussungssysteme mit einer Warnung vor dem Falschfahrer ansteuern kann.The transmission of the warning signal can also be done on a stationary communication device, can be controlled by the warning devices. It is thus possible, for example, to provide a stationary beacon at particularly vulnerable points, which can receive such warning signals and, for example, can control electronic traffic control systems with a warning to the wrong-way driver.

Als Erkennungseinrichtung des Fahrzeugs wird beispielsweise wenigstens eine Kamera verwendet, deren Bilder mit einer Bildauswertungseinrichtung zur Erkennung der Verkehrsschilder ausgewertet werden. Derartige Kameras mit einer entsprechenden Bildauswertungseinrichtung sind im Stand der Technik bereits offenbart worden.As a detection device of the vehicle, for example, at least one camera is used whose images are evaluated by an image evaluation device for detecting the traffic signs. Such cameras with a corresponding image evaluation device have already been disclosed in the prior art.

Erfindungsgemäß kann es zweckmäßig sein, die Bildauswertungseinrichtung ferner zur Auswertung von Fahrstreifenmarkierungen eines benutzten Fahrstreifens zu verwenden. Beispielsweise kann hierbei ermittelt werden, ob nach der ersten Warnung des Fahrers vor dem Befahren einer Fahrspur in der verkehrten Fahrtrichtung ein Wechsel der Fahrspur erfolgt, sodass möglicherweise der Fehler bereits korrigiert worden ist. Die Auswertung der Fahrstreifenmarkierungen kann auch dann von Bedeutung sein, wenn eine Weiterfahrt nach dem elektronischen Anhalten des Fahrzeugs nur dann ermöglicht wird, wenn durch die Satelliten-Positionsbestimmungs- und Navigationseinrichtung und/oder die Erkennungseinrichtung ein sofortiges Wenden erkannt wird. Das sofortige Wenden bringt regelmäßig ein typisches Verfahren von Fahrstreifenmarkierungen mit sich.According to the invention it may be expedient to use the image evaluation device also for the evaluation of lane markings of a used lane. For example, it can be determined here whether after the first warning of the driver before driving on a lane in the wrong direction of travel, a change of the lane takes place, so that possibly the error has already been corrected. The evaluation of the lane markings may also be of importance if a continuation of travel after the electronic stopping of the vehicle is only made possible if an immediate turning is recognized by the satellite positioning and navigation device and / or the recognition device. Immediate turning regularly introduces a typical method of lane markings.

Um ein beabsichtigtes Ausschalten der erfindungsgemäßen Sicherung gegen das Falschfahren zumindest zu erschweren, wird das Steuersignal zur Unterbrechung des Weiterfahrens generiert, wenn die Erkennungseinrichtung kein Eingangssignal erhält. Das Überkleben der beispielsweise durch eine Kamera gebildeten Erkennungseinrichtung führt somit nicht zu einer Umgehung der Sicherheitseinrichtung, da in diesem Fall das Fahrzeug vorzugsweise gar nicht gestartet werden kann.In order to at least complicate an intentional turning off the fuse according to the invention against the wrong driving, the control signal is generated to interrupt the continuation when the detection device receives no input signal. The pasting over of the detection device formed, for example, by a camera thus does not lead to a bypass of the safety device, since in this case the vehicle preferably can not be started at all.

Die erfindungsgemäße Vorrichtung zur Durchführung des Verfahrens enthält eine Satelliten-Positionsbestimmungs- und Navigationseinrichtung, eine Erkennungseinrichtung zur Erkennung von Verkehrsschildern in Fahrtrichtung, die die Einfahrt verbieten, und eine Steuereinrichtung zur Generierung eines Steuersignals zur Unterbindung der Weiterfahrt des Fahrzeugs und ist dadurch gekennzeichnet, dass die Steuereinrichtung mit der Erkennungseinrichtung und der Satelliten-Positionsbestimmungs- und Navigationseinrichtung derart verbunden ist, dass das Steuersignal generiert wird, wenn nach der Erkennung der Falschfahrt mittels der Erkennungseinrichtung während der Weiterfahrt mit Hilfe der Satelliten-Positionsbestimmungs- und Navigationseinrichtung festgestellt worden ist, dass die Weiterfahrt in die falsche Richtung erfolgt.The inventive apparatus for performing the method includes a satellite positioning and navigation device, a detection device for detecting traffic signs in the direction of travel, which prohibit the entrance, and a control device for generating a control signal to prevent the onward movement of the vehicle and is characterized in that the Control device with the recognition device and the satellite positioning and navigation device is connected such that the control signal is generated when it has been determined after the detection of the wrong drive by means of the recognition device during the onward travel with the aid of the satellite positioning and navigation device that the onward journey done in the wrong direction.

Die Erkennungseinrichtung in Form von wenigstens einer Kamera, vorzugsweise zweier Kameras, befindet sich in einer zweckmäßigen Ausführungsform an der in Fahrtrichtung nach vorn zeigenden Rückseite des mittig im Innenraum angeordneten Rückspiegels. Die Erkennungseinrichtung ist so ausgebildet, dass sie auch relativ weitwinkelig die betreffenden Verkehrsschilder, vorzugsweise auf beiden Seiten der Fahrbahn erfassen und auswerten kann.The identification device in the form of at least one camera, preferably two cameras, is located in an expedient embodiment on the rear side of the rear side of the rear mirror which is arranged centrally in the direction of travel. The recognition device is designed so that it can also detect and evaluate the relevant traffic signs, preferably on both sides of the roadway, at relatively wide angles.

Ein Ausführungsbeispiel der Erfindung soll im Folgenden anhand einer in der Zeichnung beigefügten Situationsskizze erläutert werden.An embodiment of the invention will be explained below with reference to a situation sketch attached in the drawing.

Die einzige Figur zeigt eine Autobahn mit einer Fahrbahn 2 mit drei Fahrstreifen 3, die zum Befahren in eine erste Richtung A vorgesehen sind, einem Mittelstreifen 4 sowie einer Fahrbahn 5 mit drei Fahrstreifen 6, die zum Befahren in die entgegengesetzte Richtung B vorgesehen sind.The single figure shows a highway with a lane 2 with three lanes 3, which are provided for driving in a first direction A, a median strip 4 and a lane 5 with three lanes 6, which are provided for driving in the opposite direction B.

Für die Fahrbahn 5 ist eine Ausfahrt 7 mit einer Verlangsamungsspur 8 dargestellt, die in eine der Autobahn 1 benachbarte Straße 9 mit zwei Fahrspuren 10, 11 mündet. Fahrzeuge, die die Autobahn 1 an der Ausfahrt 7 verlassen haben, können üblicherweise an der Einmündung der Ausfahrt 7 nach rechts auf die Fahrbahn 11 oder nach links auf die Fahrbahn 10 abbiegen. Neben der Einmündung der Ausfahrt 7 befindet sich die Einmündung einer Auffahrt 12, die mit einer Beschleunigungsspur 13 die Auffahrt auf die Autobahn 1 in Fahrtrichtung B ermöglicht. Um das Befahren der Auffahrt 12 durch Linksabbiegen von der Fahrspur 10 der Straße 9 zu ermöglichen, ist üblicherweise eine Linksabbiegerspur 14 vorgesehen, die den Verkehr auf die Auffahrt 12 leitet.For the lane 5, an exit 7 is shown with a slowing lane 8, which opens into a highway 1 adjacent road 9 with two lanes 10, 11. Vehicles leaving highway 1 at exit 7 can usually turn right at the junction of exit 7 onto roadway 11 or left onto roadway 10. Next to the junction of the exit 7 is the junction of a driveway 12, which allows the ramp to the highway 1 in the direction of travel B with an acceleration lane 13. In order to allow the access ramp 12 by turning left from the lane 10 of the road 9, usually a left turn lane 14 is provided, which directs traffic on the driveway 12.

Fährt ein Fahrzeug 15 beispielsweise von der Linksabbiegerspur 14 zu früh ab, kann es irrtümlich oder vorsätzlich in die Ausfahrt 7 ohne Beachtung der die Einfahrt in diese Ausfahrt 7 verbietenden Verkehrsschilder 16 einbiegen. Erfindungsgemäß ist das Fahrzeug 15 mit einer Erkennungseinrichtung für die Verkehrsschilder 16 versehen. Beim Einfahren in die Ausfahrt 7 (Position I) löst die Erkennungseinrichtung ein Warnsignal aus. Wird das Fahrzeug 15 weiter in die Ausfahrt 7 gesteuert, wird beispielsweise in der Position II ein Warnsignal nach außen, beispielsweise in Form des Signals einer eingebauten Alarmanlage, abgegeben und gleichzeitig die Warnblinkanlage des Fahrzeugs 15 aktiviert. Erkennt die in das Fahrzeug eingebaute Satelliten-Positionsbestimmungs- und Navigationseinrichtung, dass die Fahrt des Fahrzeugs auf der Ausfahrt 7 fortgesetzt wird und das Fahrzeug in den in Richtung B fließenden Verkehr einzubiegen droht (Position III) wird die Elektronik des Fahrzeugs 15 durch ein Steuersignal so beeinflusst, dass das Fahrzeug 15 zum Stillstand kommt, bevor es in den fließenden Verkehr in Richtung B auf der Autobahn 1 einbiegt.For example, if a vehicle 15 is departing too early from the left turn lane 14, it may erroneously or intentionally enter the exit 7 without regard to the traffic signs 16 prohibiting entry into that exit 7. According to the invention, the vehicle 15 is provided with a recognition device for the traffic signs 16. When entering exit 7 (position I), the detection device triggers a warning signal. If the vehicle 15 is further controlled in the exit 7, for example, in the position II, a warning signal to the outside, for example in the form of the signal of a built-in alarm system, issued while the hazard warning lights of the vehicle 15 is activated. If the satellite positioning and navigation device installed in the vehicle detects that the vehicle is traveling on exit 7 and the vehicle is entering the traffic flowing in direction B threatens (position III), the electronics of the vehicle 15 is influenced by a control signal so that the vehicle 15 comes to a stop before it turns in the flowing traffic in direction B on the highway 1.

Es kann vorgesehen sein, dass das Fahrzeug 15 durch den Fahrer nicht wieder gestartet werden kann, sodass die Freigabe erst nach dem Herbeirufen eines Kraftfahrzeugmechanikers gestartet werden kann, wodurch ein unbeaufsichtigtes erneutes Wegfahren durch den Falschfahrer verhindert wird. Es kann aber auch vorgesehen sein, dass das Fahrzeug gestartet werden kann, wenn der Fahrer, möglicherweise durch Drücken einer entsprechenden Taste, zum Ausdruck gebracht hat, dass er das Fahrzeug auf kurzem Wege sofort wenden will. Dann kann sowohl die Erkennungseinrichtung des Fahrzeugs als auch die Satelliten-Positionsbestimmungs- und Navigationseinrichtung unmittelbar nach dem Anfahren abgefragt werden, ob ein Wendevorgang eingeleitet worden ist. Dies kann von der Erkennungseinrichtung beispielsweise dadurch erkannt werden, dass das Fahrzeug über eine Mittelmarkierung 17 oder eine entsprechende Fahrbahnmarkierung wendet. Ist die Navigationseinrichtung mit Radsensoren des Fahrzeugs 15 verbunden (ABS-Sensoren) kann der Wendevorgang auch über diese Sensoren erkannt werden. Wird der Wendevorgang nicht unmittelbar nach dem Starten des Fahrzeugs ausgelöst, wird das Steuersignal zur Unterbindung des Weiterverfahrens sofort wieder ausgelöst.It can be provided that the vehicle 15 can not be restarted by the driver, so that the release can be started only after the calling of a motor vehicle mechanic, whereby unattended renewed driving away is prevented by the wrong driver. However, it can also be provided that the vehicle can be started when the driver, possibly by pressing a corresponding button, has expressed that he wants to turn the vehicle over a short distance immediately. Then, both the detection device of the vehicle and the satellite positioning and navigation device can be queried immediately after starting, whether a turning operation has been initiated. This can be recognized by the detection device, for example, by the vehicle turning over a center mark 17 or a corresponding lane marking. If the navigation device is connected to wheel sensors of the vehicle 15 (ABS sensors), the turning process can also be detected via these sensors. If the turning process is not triggered immediately after starting the vehicle, the control signal to prevent the continuation of procedure is immediately re-triggered.

Es ist erkennbar, dass das erfindungsgemäße Verfahren und die nach diesem Verfahren arbeitende Vorrichtung eine wirksame Unterbindung des Fahrens in der zugelassenen Richtung B entgegengesetzten Richtung auf einer Fahrspur 5 in den meisten Fällen verhindert.It can be seen that the method according to the invention and the device operating according to this method prevent in most cases an effective prevention of driving in the permitted direction B opposite direction on a lane 5.

Selbstverständlich sind Modifikationen und Ergänzungen des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Vorrichtung denkbar.Of course, modifications and additions of the method and apparatus of the invention are conceivable.

So ist es möglich, für den ungewöhnlichen Fall, dass der Verkehr durch Polizisten entgegen der die Einfahrt verbietenden Beschilderung 16 geleitet wird, denkbar, dass durch Drücken einer Sondertaste die Auslösung der Warnsignale und des Signals zur Unterbindung des Weiterfahrens nicht ausgelöst werden, wenn das Fahrzeug beim Einbiegen in die für die entgegengesetzte Richtung B vorgesehene Fahrbahn 5 nur unter bestimmten Bedingungen befahren wird, beispielsweise unter Einschaltung der Warnblinkanlage oder mit einer maximalen Geschwindigkeit. Ggf. kann auch die Erkennungseinrichtung so ausgebildet sein, dass mit ihr die manuelle Verkehrslenkung durch Polizisten erkennbar ist und so für diesen Ausnahmefall das Ausschalten der Warn- und Steuersignale zulässt.Thus, it is possible, in the unlikely event that the traffic is directed by police officers opposite the signage prohibiting the entrance, that by pressing a special button, the tripping of the warning signals and the signal to prevent the onward driving are not triggered when the vehicle when entering the provided for the opposite direction B road 5 is driven only under certain conditions, for example, with the involvement of the hazard warning lights or at a maximum speed. Possibly. The detection device can also be designed in such a way that the manual traffic control by police officers can be recognized with it, thus allowing the warning and control signals to be switched off for this exceptional case.

Claims (10)

  1. Method for preventing driving against the prescribed driving direction (B) with a vehicle (15) provided with a satellite position determination and navigation device, in which a detection device in the vehicle (15) is used to detect road signs (16) which are in the driving direction and prohibit entry, and, following such detection of driving in the wrong direction, a control signal for preventing continued driving is generated in the vehicle if driving is continued, characterized in that, after driving in the wrong direction has been detected using the detection device, the satellite position determination and navigation device is used, during continued driving, to check whether continued driving is being effected in the wrong direction, and in that the control signal is generated on the basis of this check.
  2. Method according to Claim 1, characterized in that a warning signal is emitted from the vehicle (15) if driving in the wrong direction has been detected.
  3. Method according to Claim 2, characterized in that the warning signal is transmitted to the vehicles in the vicinity by means of vehicle-to-vehicle communication.
  4. Method according to Claim 2 or 3, characterized in that the warning signal is transmitted to an emergency call centre by means of a mobile radio connection.
  5. Method according to one of Claims 2 to 4, characterized in that the warning signal is transmitted to a stationary communication device, and in that the communication device controls warning devices.
  6. Method according to one of Claims 1 to 5, characterized in that at least one camera is used as the detection device, the images from which camera are evaluated using an image evaluation device in order to detect the road signs.
  7. Method according to Claim 6, characterized in that the image evaluation device is also used to evaluate lane markings (17) of a lane (7) which is used.
  8. Method according to one of Claims 1 to 7, characterized in that continued driving is made possible only if the satellite position determination and navigation device and/or the detection device detect(s) immediate turning.
  9. Method according to one of Claims 1 to 8, characterized in that the control signal for preventing continued driving is generated if the detection device does not receive an input signal.
  10. Apparatus for carrying out the method according to one of Claims 1 to 9, containing a satellite position determination and navigation device, a detection device for detecting road signs (16) in the driving direction which prohibit entry, and a control device for generating a control signal for preventing continued driving of the vehicle (15), characterized in that the control device is connected to the detection device and to the satellite position and navigation device in such a manner that the control signal is generated if, after driving in the wrong direction has been detected using the detection device, it is determined, during continued driving, with the aid of the satellite position determination and navigation device that continued driving is being effected in the wrong direction.
