Abstract
Description
Die gesamte Signalgebung der Verkehrsschilder auf den Straßen müssen ausschließlich vom Fahrer als Blickkontakt zum Verkehrsschild mit der entspr. Signalwirkung über das Auge zum Gehirn und im Gedächtnis verarbeitet werden. Dazu wird im Gedächtnis das Signal umgesetzt auf das Fahrverhalten des Fahrers. Auf den Fahrer wirken somit innerhalb von wenigen Sekunden laufende sich ändernde Signale, die vorgeben, das Fahrverhalten auf die zwingend vorgeschriebenen Anordnungen einzuhalten.The entire signaling of traffic signs on the streets must only by the driver as eye contact to the traffic sign with the corresponding Signaling effects are processed via the eye to the brain and in memory. To do this, the signal is converted in the memory to the driver's driving behavior. The driver is thus affected within a few seconds changing signals that dictate the driving behavior on the mandatory to comply with the prescribed instructions.
Dabei kommt es immer wieder vor, daß Verkehrsschilder mit den vorgeschriebenen Richtlinien übersehen werden und dadurch die Vorschriften auf das Verkehrsverhalten nicht eingehalten werden.It happens again and again that traffic signs with the prescribed guidelines are overlooked and thereby the regulations not be adhered to the traffic behavior.
Zusätzlich kommt erschwerend hinzu, daß vielfach die Aufhebung der entsprechenden Vorschrift, wie z. B. Geschwindigkeitsbegrenzung oder Überholverbot nicht wahrgenommen wird.To make matters worse, the abolition of the corresponding regulation, such as B. speed limit or No overtaking is observed.
Ebenso passiert es immer wieder, daß zwar Verkehrsschilder kurzzeitig wahrgenommen wurden, aber man nicht bleibend registriert hatte, welche Aussage mit dieser Verkehrsvorschrift gemacht wurde.It also happens again and again that traffic signs are brief were perceived, but one had not permanently recorded which statement was made with this traffic regulation.
Mit dem Verkehrszeichen-Erfassungs-System (VES) wird dem Fahrer das Verkehrszeichen, an dem er vorbeifährt in das Fahrzeug signalisiert. Es bleibt als Kennzeichnung solange in seinem Blickfeld, bis es vom weiteren Verkehrszeichen als aufgehoben signalisiert wird. With the traffic sign detection system (VES), the driver gets that Traffic sign that he is driving past in the vehicle. It remains as Marking in his field of vision until it is from the further traffic sign is signaled as canceled.
Als Erfindung wird das technische Verfahren beschrieben:
Vom Fahrzeug wird per umlaufenden Richtstrahl (2) von einer Sende- und
Empfangsstation (S + E-Station) (1) der voraus liegende Fahrbereich laufend
abgetastet auf vorhandene Verkehrsschilder (3).The technical method is described as the invention:
The vehicle is continuously scanned for existing traffic signs ( 3 ) using a rotating beam ( 2 ) from a transmitting and receiving station (S + E station) ( 1 ).
An den Verkehrsschildern sind Erkennungszeichen (4) angebracht, die von dem Richtstrahl (2) erfaßt werden.Identification signs ( 4 ) are attached to the traffic signs and are detected by the directional beam ( 2 ).
Ein auf dem Erkennungszeichen aufgebrachter Code (5) wird als Signal erfaßt und an die S + E-Station, die den Richtstrahl aussendete, zurückgesendet. Der Code beinhaltet die Information, die das Verkehrszeichen darstellt.A code ( 5 ) applied to the identification mark is detected as a signal and sent back to the S + E station which emitted the directional beam. The code contains the information that represents the traffic sign.
Die S + E-Station gibt die Information vom Verkehrszeichen auf ein im Fahrzeug eingebauten Auswerter (6).The S + E station transfers the information from the traffic sign to an evaluator ( 6 ) installed in the vehicle.
Vom Auswerter wird die Information auf ein im Bereich der Instrumentierung eingebautes Display geleitet.From the evaluator, the information becomes one in the area of instrumentation built-in display.
Die Information des Verkehrsschildes bleibt so lange auf dem Display sichtbar, bis ein anderes Verkehrsschild eine Aufhebung der Fahrvorschrift oder eine andere Richtlinie bringt.The information on the traffic sign remains visible on the display until until another traffic sign revokes the driving regulations or brings different guideline.
Der Richtstrahl kann durch: Laser, Infrarot, Funk oder ähnliche Verfahren erzeugt werden.The beam can be generated by: laser, infrared, radio or similar processes become.
Der Abtastrichtstrahl soll in dem vorausliegenden Fahrbereich als Vorhang wirken.The scanning beam should act as a curtain in the driving area ahead Act.
Der Vorhang kann erreicht werden durch zeilenförmiges Abtasten.The curtain can be reached by scanning in rows.
Die Sende- und Empfangsstation für den Richtstrahl kann im Fahrzeug hinter dem Rückspiegel angeordnet werden, oder aber auch an anderer geeigneter Stelle.The transmitting and receiving station for the directional beam can be in the vehicle behind the Rear-view mirrors can be arranged, or at another suitable location.
Von der S + E-Station wird das Signal im Fahrzeug über Kabel an den Auswerter geleitet, der beim Display in der Instrumententafel mit untergebracht wird. Der Richtstrahl soll so gestaltet sein, daß er auch bei Dunkelheit oder Nebel gesichert das Erkennungszeichen auf dem Verkehrsschild erkennt und auswertet.The signal in the vehicle is sent from the S + E station via cable to the evaluator headed, which is included in the display in the instrument panel. The directional beam should be designed so that it also in the dark or fog Secured recognizes the sign on the traffic sign and evaluates.
Außerdem ist die Stärke und Art des Richtstrahls so anzupassen, daß keine Lichtstrahlen z. B. von entgegenkommenden Fahrzeugen oder andere Störreflexe diesen beeinflussen.In addition, the strength and type of the beam should be adjusted so that none Light rays z. B. from oncoming vehicles or other interference reflections influence this.
Das Erkennungszeichen auf den Verkehrsschildern wird zweckmäßigerweise als Strichcode oder Ähnliches ausgebildet. Kann aber auch in anderer Form dargestellt werden.The identifier on the traffic signs is expediently as Barcode or the like. But can also in other forms being represented.
Um das Erkennungszeichen auch bei leichter Verschmutzung des Verkehrsschildes gesichert vom Richtstrahl zu erfassen, ist das Erkennungszeichen mit entsprechenden Reflexpigmenten zu versehen.To the identification mark even if the To capture the traffic sign secured by the directional beam is that Identifying signs with appropriate reflective pigments.
Zur Einstellung und Wahrnehmung des Richtstrahls sollte an den Verkehrsschildern ein Reflexpunkt aufgebracht werden, der den Richtstrahl während der Übertragung zum Fahrzeug fixiert. Dadurch wird eine Stabilisierung der Ausrichtung zur Abtastung des Strichcodes erreicht. For the adjustment and perception of the directional beam, the Traffic signs are applied to a reflex point that is the directional beam fixed during transmission to the vehicle. This creates a stabilization the alignment for scanning the bar code is reached.
Desweiteren soll der Richtstrahl auch Leuchtzeichen, bei denen zusätzlich der Codestreifen mit eingegeben wird, zur Verkehrsregelung erkennen.Furthermore, the directional beam should also include illuminated signs, in which the Code stripe is entered to recognize traffic control.
Die Erkennungszeichen können nachträglich auf den vorhandenen Verkehrsschildern aufgeklebt oder anderweitig befestigt werden.The identifying marks can subsequently be added to the existing ones Traffic signs are glued or otherwise attached.
Die Erkennungszeichen sind witterungsbeständig auszubilden und ebenso die Anbringung auf dem Verkehrsschild.The identifying marks are to be weather-resistant and so are the Placement on the traffic sign.
Dieses Verkehrzeichen-Erfassungs-System (VES) stellt ein kostengünstiges Verfahren dar, da Verkehrszeichen durch die öffentliche Hand aufgestellt werden und diese hieraus finanziert sind, sollten durch die öffentliche Hand nur geringe Kosten durch die zusätzlich Kennzeichnung über den Codestreifen entstehen. Zumal diese auch nachträglich auf die vorhandenen Verkehrszeichen aufgebracht werden können.This traffic sign detection system (VES) provides an inexpensive Procedures because road signs are set up by the public sector and these are financed from this should only be low by the public sector Costs arise from the additional labeling via the code strip. Especially since these are subsequently applied to the existing traffic signs can be.
Ein weiterer Vorteil besteht darin, daß die öffentlichen Verkehrszeichen zur Übertragung der Signalgebung passiv gegenüber anderen Systemen wirken. Aktiv sind nur die Systeme im Fahrzeug.Another advantage is that the public traffic sign for Signaling transmission have a passive effect on other systems. Only the systems in the vehicle are active.
Eine weitere Möglichkeit besteht, die Informationen als Warnung bei abweichender Fahrweise gegenüber der Verkehrsinformation anzuzeigen und evtl. Warnsignale abzugeben.Another option is to include the information as a warning display a different driving style compared to the traffic information and possibly Give warning signals.
