Abstract
Description
Die Erfindung betrifft ein Erfassungsgerät zur Erkennung von Verkehrszeichen für den Einsatz in einem Kraftfahrzeug.The The invention relates to a detection device for detecting traffic signs for the Use in a motor vehicle.
Die Einhaltung vorgegebener Geschwindigkeiten im Straßenverkehr ist oftmals auch deshalb problematisch, weil Fahrer von Kraftfahrzeugen aufgrund der vielen und oft unübersichtlich angeordneten Verkehrszeichen oftmals Probleme mit der Erfassung der Verkehrszeichen haben. Oft werden Verkehrszeichen aber auch nur wegen fehlender Aufmerksamkeit übersehen, so dass die korrekte Fahrgeschwindigkeit dann nicht eingehalten wird und Verkehrsgefährdungen die Folge sein können.The Compliance with specified speeds in traffic is often also problematic because drivers of motor vehicles because of the many and often confusing arranged traffic signs often have problems with the detection the traffic signs have. Often traffic signs are also just overlooked because of lack of attention, so the correct Driving speed is then not respected and traffic hazards the result can be.
Der Erfindung liegt die Aufgabe zugrunde, ein Erfassungsgerät zur Erkennung von Verkehrszeichen zu schaffen, welches automatisch eine Geschwindigkeitsregelung durchführen und/oder einen die Fahrgeschwindigkeit betreffenden Hinweis geben kann.Of the Invention is based on the object, a detection device for detection of traffic signs, which automatically creates a cruise control carry out and / or can give a hint concerning the driving speed.
Die Lösung dieser Aufgabe erhält man durch die im Anspruch 1 angegebenen Merkmale. Der vor dem Kraftfahrzeug befindliche Verkehrsraum wird mittels eines Überwachungsgeräts überwacht, das in Abhängigkeit von einem jeweils erkannten Verkehrszeichen ein Steuersignal erzeugt, mit dem eine Hinweiseinrichtung und/oder ein Geschwindigkeitsregelungseinrichtung betätigt werden kann. Das Überwachungsgerät kann eine Videokamera und ggf. auch ein zusätzliches Distanzmessgerät oder eine sonstige Erfassungseinheit enthalten, so dass das von der Videokamera erzeugte Videosignal mit abgespeicherten Videodaten von unterschiedlichen Verkehrszeichen im Erfassungsgerät verglichen werden können, Dabei können den Videosignalen zugeordnete Distanzangaben zur eindeutigen Erkennung von Verkehrszeichen hilfreich sein, da Verkehrszeichen in vorgegebenen Höhen und vorgegebenen Abständen zum Verkehrsraum angeordnet sein müssen. Außerhalb von zulässigen Distanzen angeordnete Verkehrszeichen können dann als nicht relevant vom Erfassungsgerät erkannt werden.The solution receives this task one by the features specified in claim 1. The front of the vehicle located traffic space is monitored by means of a monitoring device, that in dependence generates a control signal from a respectively recognized traffic sign, with a hinting device and / or a speed control device actuated can be. The monitor can have a Video camera and possibly also an additional distance measuring device or a other capture unit included, so that by the video camera generated video signal with stored video data of different Traffic sign in the detection device can be compared It can The distances assigned to the video signals for unambiguous recognition Of traffic signs be helpful because traffic signs in given Heights and given distances to Traffic space must be arranged. Outside from admissible Distances arranged traffic signs can then be considered not relevant from the acquisition device be recognized.
Mit dem erfindungsgemäßen Erfassungsgerät können insbesondere die üblichen runden Verkehrszeichen erkannt werden, die Geschwindigkeitsbegrenzungen und die Aufhebung von Geschwindigkeitsbegrenzungen betreffen. Außerdem soll auch vorgesehen sein, dass Ortsschilder am Ortsanfang und am Ortende vom Erfassungsgerät erkannt werden und eine entsprechende Geschwindigkeitsanpassung eingeleitet oder angezeigt werden kann.With The detection device according to the invention can in particular the usual round traffic signs are detected, the speed limits and the lifting of speed limits. In addition, should also be provided that place signs at the beginning and at the end of town from the acquisition device be recognized and a corresponding speed adjustment can be initiated or displayed.
Grundsätzlich können auch noch weitere Sensoren zur Identifizierung der Verkehrszeichen zusätzlich eingesetzt werden, beispielsweise Infrarotsensoren oder Radarsensoren.Basically, too even more sensors for identifying the traffic signs additionally used be, for example, infrared sensors or radar sensors.
Eine mögliche Ausführungsform der Erfindung kann mit einem Mikroprozessor bestückt sein, der sowohl mit dem Bordcomputer des Kraftfahrzeugs als auch mit einem Datenspeicher in Verbindung steht, in welchem verkehrszeichentypische Videodaten für die Vergleichsmessungen abgelegt sind. Ausgangsseitig kann der Mikroprozessor ein Display und/oder eine akustische Anzeige steuern, um dem Fahrer bei sich ändernden Geschwindigkeitsvorgaben einen entsprechenden Hinweis geben zu können.A possible embodiment The invention may be equipped with a microprocessor, both with the On-board computer of the motor vehicle as well as with a data memory in which traffic sign typical video data for the Comparative measurements are stored. On the output side, the microprocessor control a display and / or an audible indication to the driver at changing Speed specifications to be able to give a corresponding note.
Es besteht auch die Möglichkeit, dass das Erfassungsgerät Daten aus einem Navigationssystem mit hinzuzieht, um beispielsweise eine noch sicherere Erkennung der Ortsschilder zu ermöglichen.It there is also the possibility that the detection device Data from a navigation system is involved, for example to allow even safer detection of city signs.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The Invention will now be described with reference to a drawing embodiment explained in more detail.
