Die Aufgabe der Erfindung besteht darin, ein Verfahren und eine Vorrichtung zur Erkennung der Annäherung eines Fahrzeugs an ein Objekt anzugeben, die mit einer reduzierten Anzahl von Bauteilen auskommen.The The object of the invention is a method and a device for detecting the approach of a vehicle to an object specify that manage with a reduced number of components.
Diese Aufgabe wird durch ein Verfahren mit den im Anspruch 1 angegebenen Merkmalen bzw. durch eine Vorrichtung mit den im Anspruch 10 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.These The object is achieved by a method with the specified in claim 1 Characteristics or by a device with the specified in claim 10 Characteristics solved. Advantageous embodiments and developments The invention are defined in the dependent claims specified.
Die Vorteile der Erfindung bestehen insbesondere in einem kompakten Aufbau, bei welchem in die Rückleuchte eines Fahrzeugs sowohl die zur Fahrzeugbeleuchtung notwendigen Leuchtmittel als auch die zum Erkennen der Annäherung des Fahrzeugs an ein Objekt benötigten Bauteile integriert sind und bei welchem eines oder mehrere der ohnehin vorhandenen Leuchtmittel zum Ausstrahlen des für das Erkennen benötigten Lichtes verwendet werden und bei welchem vorzugsweise auch eines oder mehrere der ohnehin vorhandenen Leuchtmittel zum Empfangen des für das Erkennen benötigten, von einem Objekt reflektierten Lichtes verwendet werden. Zusätzliche Sende- und Empfangsmittel, wie sie beim Stand der Technik vorgesehen sind, werden nicht benötigt.The Advantages of the invention are in particular in a compact Structure in which in the tail light of a vehicle both the necessary for vehicle lighting bulbs and for detecting the approach of the vehicle to an object required components are integrated and in which a or more of the already existing bulbs for broadcasting of the light needed for the recognition and in which preferably one or more of the Any existing bulbs for receiving the for needed the recognition, reflected from an object Light can be used. Additional transmitting and receiving means, as provided in the prior art are not needed.
Die Auswertung des detektierten reflektierten Lichtes zur Erkennung einer Annäherung des Fahrzeugs an ein Objekt erfolgt in vorteilhafter Weise mittels einer meist ohnehin vorhandenen Auswerteeinheit. Bei dieser meist ohnehin vorhandenen Auswerteeinheit handelt es sich vorzugsweise um den Steuerrechner, der Bestandteil der Leuchtenbaueinheit ist und zur Ansteuerung der dort vorgesehenen Leuchtmittel dient.The Evaluation of the detected reflected light for detection an approach of the vehicle to an object takes place in Advantageously, by means of a mostly anyway existing evaluation. This evaluation unit, which is usually available anyway, is concerned preferably to the control computer, the part of the lighting unit is and serves to control the lamps provided there.
In vorteilhafter Weise werden – um die Einflüsse von Fremdlicht und Streulicht zu minimieren – gepulste Signale ausgestrahlt. Dabei kann unter Verwendung eines Korrelationsverfahrens zwischen einer Reflexion von eigenem Licht und anderen Lichtquellen unterschieden werden.In an advantageous manner - in order to minimize the effects of extraneous light and stray light - pulsed signals are emitted. In this case, using a correlation method between ei ner reflection of own light and other light sources are distinguished.

Nach alledem erfolgt bei der vorliegenden Erfindung eine Erkennung der Annäherung eines Fahrzeugs an ein Objekt unter Verwendung ohnehin vorhandener Leuchtmittel des Fahrzeugs. Vorzugsweise handelt es sich dabei um in der Rückleuchte des Fahrzeugs vorgesehene, ohnehin vorhandene Leuchtdioden. Diese werden in vorteilhafter Weise gepulst betrieben, um Einflüsse von Fremdlicht und Streulicht zu minimieren. Zur Auswertung der vom Objekt reflektierten Signale wird vorzugsweise ein ohnehin vorhandener Steuerrechner verwendet, beispielsweise der Steuerrechner der jeweiligen Leuchteneinheit, wobei dieser Steuerrechner entweder in die Leuchteneinheit integriert ist oder mit dieser verbunden ist.To All this is done in the present invention, a recognition of Approaching a vehicle to an object using Any existing bulbs of the vehicle. Preferably it is intended to be in the tail light of the vehicle, Any existing light-emitting diodes. These are pulsed in an advantageous manner operated to influence foreign light and stray light minimize. For evaluation of the signals reflected by the object an already existing control computer is preferably used, for example, the control computer of the respective lighting unit, wherein this control computer integrated either in the lamp unit is or is connected to this.
Eine alternative Ausführungsform besteht darin, bei dem Verfahren zur Erkennung der Annäherung eines Fahrzeugs an ein Objekt beispielsweise mittels eines ohnehin vorhandenen Frontscheinwerfers oder eines ohnehin vorhandenen Rückfahrscheinwerfers weißes Licht auszustrahlen und das reflektierte weiße Licht auszuwerten.A alternative embodiment is in the method for detecting the approach of a vehicle to an object for example, by means of an existing headlight anyway or an already existing reversing spotlight white To emit light and to evaluate the reflected white light.
Eine weitere Alternative besteht darin, beispielsweise mittels der ohnehin vorhandenen Rücklichter buntes Licht auszustrahlen und das reflektierte bunte Licht auszuwerten.A Another alternative is, for example, by means of anyway existing taillights emit colorful light and to evaluate the reflected colorful light.
Weiterhin ist es auch möglich, mittels eines ohnehin vorhandene Infrarotscheinwerfers Infrarotlicht auszustrahlen und das reflektierte Infrarotlicht auszuwerten.Farther It is also possible by means of an already existing infrared headlamp To emit infrared light and to evaluate the reflected infrared light.
Eine vorteilhafte Weiterbildung der Erfindung besteht darin, bei der Erkennung der Annäherung eines Fahrzeugs an ein Objekt mehrere ohnehin vorhandene und miteinander synchronisierte Leuchtmittel des Fahrzeugs zu verwenden, beispielsweise die linke und die rechte Rückleuchte des Fahrzeugs. Dies verbessert die Lokalisierung des Objektes relativ zum Fahrzeugs.A advantageous development of the invention is in the Detecting the approach of a vehicle to an object several existing and synchronized with each other bulbs of the vehicle, for example, the left and right Taillight of the vehicle. This improves the localization of the object relative to the vehicle.
