Der Scheinwerfer (10) weist eine erste Leuchtweite auf, die der Leuchtweite im normalen Fahrbetrieb entspricht. Weiterhin ist ein Erkennungsmittel zur Erkennung eines Nebelzustands vorgesehen. Die Leuchtweite des Scheinwerfers (10) wird bei Erkennung eines Nebelzustands reduziert. Die erfindungsgemäße Vorrichtung weist eine Steuergerät auf, welches zur Durchführung des oben beschriebenen Verfahrens dient.A method for controlling a headlight (10), in particular a motor vehicle, is proposed. The headlight (10) has a first light range which corresponds to the light range during normal driving. Furthermore, a detection means is provided for detecting a fog condition. The headlight range (10) is reduced when a fog condition is detected. The device according to the invention has a control unit which is used to carry out the method described above.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Steuern eines Scheinwerfers, insbesondere für ein Kraftfahrzeug, nach Gattung der unabhängigen Ansprüche.The The invention relates to a method and a device for controlling a headlamp, in particular for a motor vehicle, by category the independent one Claims.
Es sind schon zahlreiche Verfahren und Vorrichtungen zum Steuern von Scheinwerfern bekannt. Beispielsweise ist aus der DE-A-19962394 ein Verfahren zum automatischen Schalten von Außenbeleuchtungseinrichtungen eines Kraftfahrzeugs bekannt, bei der die Scheinwerfer des Kraftfahrzeugs in Abhängigkeit von der Position des Fahrzeugs, der Uhrzeit und der Außenhelligkeit geschaltet werden. Weiterhin ist bekannt, die horizontale Auslenkung des Lichtkegels der Scheinwerfer in Abhängigkeit des Lenkwinkels vorzusehen, sodass der Lichtkegel der Scheinwerfer in einer Kurve in Richtung der Fahrbahn gerichtet ist.It There are already numerous methods and devices for controlling Headlamps known. For example, from DE-A-19962394 a method for automatically switching outdoor lighting devices a motor vehicle known in which the headlights of the motor vehicle dependent on from the position of the vehicle, the time of day and the external brightness be switched. Furthermore, it is known that the horizontal deflection of the To provide light cones of the headlights as a function of the steering angle, so that the light cone of the headlights in a curve in the direction the roadway is directed.
Darüber hinaus ist es bekannt, bei Kraftfahrzeugen eine so genannte Leuchtweitenregelung vorzusehen. Hierbei wird die vertikale Ausrichtung des Scheinwerfers, bzw. des Lichtkegels des Scheinwerfers, in Abhängigkeit der Beladung des Kraftfahrzeugs verändert. Auf diese Weise wird gewährleistet, dass die Leuchtweite der Scheinwerfer bei einem beladenen Kraftfahrzeug im Verhältnis zum unbeladenen Kraftfahrzeug konstant bleibt.Furthermore It is known in motor vehicles, a so-called headlight range control provided. Here, the vertical orientation of the headlamp, or the light cone of the headlamp, depending on the load of the motor vehicle changed. This will ensure that the headlight range of the headlights in a loaded motor vehicle in relation to remains constant to the unloaded motor vehicle.
Darüber hinaus sind auch Nebelscheinwerfer für Kraftfahrzeuge bekannt, welche eine niedrigere Leuchtweite als die normalen Scheinwerfer, im so genannten Abblendlicht, aufweisen und damit das Frontfeld des Kraftfahrzeugs bei Nebel stärker beleuchten, da bei derartigen Nebelzuständen die Sicht des Fahrers durch eine zu hohe Leuchtweite aufgrund der Lichtreflektion durch den Nebel eher verringert wird.Furthermore are also fog lights for Motor vehicles are known, which have a lower beam range than the normal headlights, in the so-called low beam, and have so that the front panel of the motor vehicle more intense in fog, because of such fog conditions the driver's view due to too high a light range due to the Light reflection through the fog is rather reduced.
Aus verschiedenen Veröffentlichungen sind darüber hinaus Sensoren bekannt, welche Nebel zu erkennen vermögen und bei der Erkennung eines solchen Nebelzustands die Scheibenwischvorrichtung in Betrieb setzen oder die Empfindlichkeit für das Inbetriebsetzen von Scheibenwischern erhöhen.Out various publications are over it In addition, sensors known, which are able to detect fog and upon detection of such fog condition, the windshield wiper device put into operation or the sensitivity for the commissioning of windscreen wipers increase.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Verfahren mit den Merkmalen des Hauptanspruchs hat den Vorteil, dass die Sicht für den Fahrer des Kraftfahrzeugs bei Nebel wesentlich verbessert wird. Hierzu wird die Leuchtweite der normalen Fahrzeugscheinwerfer bei Erkennung eines Nebelzustands reduziert.The inventive method Having the features of the main claim has the advantage that the view for the Driver of the motor vehicle is significantly improved in fog. For this purpose, the headlight range of the normal vehicle headlights upon detection a fog state reduced.
Durch die in den Unteransprüchen aufgeführten Maßnahmen ergeben sich vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Merkmale.By in the subclaims listed activities result in advantageous developments and improvements of specified in the main claim features.
Besonders vorteilhaft ist es, wenn das Erkennungsmittel als Schalter ausgebildet ist, der zum Einschalten der Nebelscheinwerfer oder der Nebelschlussleuchte des Kraftfahrzeugs dient, sodass die Leuchtweite des Scheinwerfers durch Einschalten des Nebelscheinwerfers oder der Nebelschlussleuchte reduziert wird. Hierdurch kann auf sehr einfache Weise die Sicht für den Fahrer verbessert werden.Especially it is advantageous if the detection means designed as a switch is to turn on the fog lights or the rear fog lamp of the motor vehicle, so that the beam range of the headlamp by switching on the fog lamp or the rear fog lamp is reduced. As a result, in a very simple way the view for the Driver to be improved.
Das Erkennungsmittel kann aber auch als optischer Sensor ausgebildet sein, sodass die Leuchtweite automatisch reduziert wird, wenn der optische Sensor einen Nebelzustand erkennt.The Recognition means can also be designed as an optical sensor so that the headlight range is automatically reduced when the optical Sensor detects a fog condition.
In einer besonders einfachen und kostengünstigen Ausführung wird die Leuchtweite des Scheinwerfers durch die Neigung des Scheinwerfers reduziert.In a particularly simple and inexpensive design is The headlamp range of the headlamp is reduced by the inclination of the headlamp.
Ebenso vorteilhaft ist es, wenn der Scheinwerfer einen Reflektor aufweist und die Leuchtweite durch eine Bewegung oder Verstellung des Reflektors reduziert wird.As well It is advantageous if the headlamp has a reflector and the beam range by a movement or adjustment of the reflector is reduced.
Weiter verbessert wird das Verfahren dadurch, dass der Nebelzustand durch eine Größe, beispielsweise die Nebeldichte, charakterisiert wird, das Erkennungsmittel diese Größe erkennt und die Reduzierung der Leuchtweite in Abhängigkeit dieser Größe erfolgt.Further the method is improved by the fact that the fog state a size, for example the fog density is characterized, the detection means this Size recognizes and the reduction of the beam range depending on this size is done.
Besonders vorteilhaft ist es hierbei, wenn die größte Leuchtweite des Scheinwerfers beim Abblendlicht dann eingestellt wird, wenn kein Nebelzustand erkannt wird.Especially It is advantageous if the largest beam range of the headlamp when dipped then set when no fog state is recognized.
Die erfindungsgemäße Vorrichtung zum Steuern eines Scheinwerfers hat den Vorteil, dass ein Steuergerät vorgesehen ist, das zur Durchführung des Verfahrens nach einem der vorhergehenden Ansprüche vorgesehen ist.The inventive device for controlling a headlight has the advantage that a control device provided that is to carry out the Method according to one of the preceding claims is provided.
