Description
Die Erfindung betrifft ein Leuchtsystem für ein Kraftfahrzeug, mit einer Steuereinheit, mit mindestens einer Bilderfassungseinheit, mit mindestens einer Lichteinheit, die mindestens eine Lichtquelle aufweist, wobei die Lichteinheit mittels mindestens eines Stellantriebes einstellbar ist und wobei die Lichteinheit im aktivierten Zustand eine Lichtverteilung mit Hell-Dunkel-Grenzen, kurz HDGs, erzeugt, derart, dass eine Justage der Lichteinheit mittels der Steuereinheit durchführbar ist. Desweiteren betrifft die Erfindung ein Verfahren zur Justage einer derartigen Lichteinheit.The invention relates to a lighting system for a motor vehicle, with a control unit, with at least one image acquisition unit, with at least one light unit, which has at least one light source, the light unit being adjustable by means of at least one actuator and the light unit in the activated state providing a light distribution with bright- Dark boundaries, HDGs for short, are generated in such a way that the light unit can be adjusted by means of the control unit. The invention also relates to a method for adjusting such a light unit.

Somit stellt sich die Aufgabe, ein Leuchtsystem bzw. ein Verfahren zur Justage einer Lichteinheit eines derartigen Leuchtsystems bereitzustellen, wodurch der oben genannte Nachteil vermieden wird.The object is thus to provide a lighting system or a method for adjusting a light unit of such a lighting system, whereby the above-mentioned disadvantage is avoided.
Diese Aufgabe wird durch ein Leuchtsystem für ein Kraftfahrzeug dadurch gelöst, dass mittels der Bilderfassungseinheit mindestens ein charakteristischer Punkt
Diese individuelle Anpassung erfolgt hierbei lediglich durch die Erfassung von mindestens einem Punkt der charakteristischen Lichtverteilung, beispielsweise einer HDG, sowie durch die besondere Ausführung der Steuereinheit, wodurch keine aufwendige Sensorik zur Umwelterfassung notwendig ist.This individual adaptation takes place here only through the detection of at least one point of the characteristic light distribution, for example an HDG, as well as through the special design of the control unit, which means that no complex sensor system is necessary for environmental detection.
Als besonders vorteilhaft hat es sich erwiesen, dass in der Steuereinheit als Rechenoperation ein Clusterverfahren hinterlegt ist. Hierdurch ist auf besonders einfache und schnelle Weise eine Ermittlung der Fehlstellung möglich. Desweiteren ist in der Steuereinheit eine Plausibilitätsprüfung für die Ermittlung des charakteristischen Punktes
Dadurch, dass die Scheinwerfergrundebene
Des Weiteren wird die Aufgabe durch ein Verfahren zur Justage einer Lichteinheit eines derartigen Leuchtsystems dadurch gelöst, dass in einem ersten Schritt die HDGs auf einer Fläche abgebildet werden, dass in einem zweiten Schritt mindestens ein charakteristischer Punkt
Hierbei ist es besonders vorteilhaft, wenn im zweiten Schritt das Plausibilitätsverfahren derart durchgeführt wird, dass eine Anzahl von Frames einer Bildfolge hinsichtlich des charakteristischer Punkt
