Description
Die Erfindung betrifft ein Verfahren und eine Anordnung zur Ermittlung des Verschmutzungsgrades zumindest eines Glasscheibenabschnittes eines Fahrzeugleuchtenmoduls gemäß dem Oberbegriff des Patentanspruches 1 und 10.The The invention relates to a method and an arrangement for detection the degree of soiling at least one glass pane section a vehicle lamp module according to the preamble of Claims 1 and 10.
Herkömmliche Fahrzeuge, insbesondere Kraftfahrzeuge, Lastwagen oder Motorräder weisen unterschiedliche Beleuchtungssysteme auf, die beispielsweise mehrere Fahrzeugleuchtenmodule aufweisen, die an der Front- oder Heckseite sowie an den beiden Längsseiten eines Fahrzeugs angebracht sind.conventional Vehicles, especially motor vehicles, trucks or motorcycles have different Lighting systems, for example, several vehicle lighting modules have on the front or rear side and at the two long sides a vehicle are mounted.
Derartige Fahrzeugleuchtenmodule bestehen aus einem einen Innenraum aufweisenden Leuchtengehäuse mit zumindest einem Glasscheibenabschnitt, über welchen das von zumindest einer im Innenraum des Leuchtengehäuses angeordneten Leuchte erzeugte Licht nach außen abgestrahlt wird. Die abgestrahlte Lichtleistung der Leuchte ist bei einem hohen Verschmutzungsgrad des zumindest einen Glasscheibenabschnittes, beispielsweise eines Klarglasscheibenabschnittes oder eines Streuscheibenabschnittes deutlich reduziert. Hierdurch ist sowohl die Ausleuchtung der Fahrbahn als auch die Sichtbarkeit des Fahrzeuges durch den Gegenverkehr verschlechtert.such Vehicle lighting modules consist of an interior housing having a lamp housing at least one glass pane section over which at least a lamp arranged in the interior of the lamp housing produced Light to the outside is emitted. The radiated light output of the luminaire is at a high degree of contamination of the at least one glass pane section, for example, a clear glass pane section or a diffuser section significantly reduced. As a result, both the illumination of the road as well as the visibility of the vehicle by oncoming traffic deteriorated.
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Möglichkeit zu schaffen, den Verschmutzungsgrad zumindest des Glasscheibenabschnitts eines Fahrzeugleuchtenmoduls zu erkennen, um geeignete Maßnahmen zur Beseitigung der dadurch bedingten verschlechterten Sichtverhältnisse für den Fahrer als auch die Sichtbarkeit des Fahrzeuges für die weiteren Verkehrsteilnehmer einleiten zu können.outgoing From this prior art, it is an object of the invention, a possibility to create the degree of contamination at least the glass pane section of a vehicle light module to detect appropriate action to eliminate the resulting deteriorated visibility for the Driver as well as the visibility of the vehicle for the others To be able to initiate road users.
Die Aufgabe wird durch ein Verfahren und eine Anordnung gemäß den unabhängigen Ansprüchen gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der abhängigen Ansprüche.The The object is achieved by a method and an arrangement according to the independent claims. advantageous Further developments are the subject of the dependent claims.
Zur Ermittlung des Verschmutzungsgrades des zumindest einen Glasscheibenabschnittes eines Fahrzeugleuchtenmoduls, bei dem über zumindest eine im Fahrzeugleuchtenmodul angeordnete Leuchte Licht mit einer Lichtleistung erzeugt wird, wird vorteilhaft die Lichtleistung des durch den zumindest einen verschmutzten Glasscheibenabschnitt hindurch tretenden Lichtes und/oder die Lichtleistung des durch den zumindest einen verschmutzten Glasscheibenabschnitt reflektierte Lichtes gemessen und abhängig davon der Verschmutzungsgrad des zumindest einen Glasscheibenabschnittes ermittelt. Dies hat den Vorteil, dass die Lichtleistung der Lampeneinheit abhängig vom ermittelten Verschmutzungsgrad des Glasscheibenabschnittes des Fahrzeugleuchtenmoduls angepasst werden kann, um somit auch bei verschmutzen Fahrzeugleuchtenmodulen eine vorgegebene Mindestleuchtleistung sicherstellen zu können. Hierbei ist eine Anpassung der Lichtleistung nur so weit möglich, dass die Lebensdauer der Leuchte nicht merklich reduziert wird.to Determining the degree of contamination of the at least one glass pane section a vehicle lighting module, wherein at least one in the vehicle lighting module arranged light is generated light with a light output, Advantageously, the light output of the at least one dirty glass pane section passing light and / or the light output of the at least one dirty glass pane section reflected light measured and depending on the degree of pollution the determined at least one glass pane section. this has the advantage that the light output of the lamp unit depends on determined degree of contamination of the glass pane portion of the vehicle lamp module can be adjusted, so even with dirty vehicle lighting modules to be able to ensure a given minimum luminous power. in this connection is an adjustment of the light output only so far possible that the life of the lamp is not significantly reduced.
Die Lichtleistung wird mittels einer im Fahrzeugleuchtenmodul integrierten und/oder im Bereich des Glasscheibenabschnittes des Fahrzeugleuchtenmoduls angeordneten Sensoreinheit gemessen und zur Ermittlung des Verschmutzungsgrades die gemessene Lichtleistung mit einem vorgegebenen Lichtleistungssollwert verglichen. Anschließend wird abhängig vom ermittelten Verschmutzungsgrad die Lichtleistung des von der Leuchte erzeugten Lichtes erhöht, um besonders vorteilhaft die verschmutzungsbedingte Reduzierung der Lichtleistung des Fahrzeugleuchtenmoduls zumindest teilweise zu kompensieren.The Light output is integrated by means of a built-in vehicle light module and / or in the region of the glass pane section of the vehicle lighting module arranged sensor unit and measured to determine the degree of contamination the measured light output with a given light power setpoint compared. Subsequently becomes dependent determined by the degree of pollution, the light output of the Increased luminaire of generated light, particularly advantageous the pollution-related reduction the light output of the vehicle lighting module at least partially to compensate.
Gemäß einer vorteilhaften Ausbildung wird abhängig vom ermittelten Verschmutzungsgrad zumindest eine weitere im Fahrzeugleuchtenmodul vorgesehene Leuchte und/oder ein weiteres Fahrzeugleuchtenmodul zu- oder abgeschaltet.According to one advantageous training depends on the determined degree of contamination at least one further lamp provided in the vehicle lighting module and / or another vehicle lighting module switched on or off.
Zusätzlich oder alternativ wird abhängig vom ermittelten Verschmutzungsgrad zumindest ein im Fahrzeug vorgesehenes Leuchtenreinigungssystem gesteuert oder geregelt.Additionally or alternatively becomes dependent determined pollution degree at least one provided in the vehicle Luminaire cleaning system controlled or regulated.
Vorteilhaft wird der ermittelte Verschmutzungsgrad dem Fahrer des Fahrzeuges über eine Anzeigeneinheit angezeigt.Advantageous the determined degree of contamination is the driver of the vehicle via a display unit displayed.
Weitere vorteilhafte Ausbildungen der Erfindung, insbesondere eine Anordnung zur Ermittlung des Verschmutzungsgrades zumindest eines Glasscheibenabschnittes eines an ein Steuergerät angeschlossenen Fahrzeugleuchtenmoduls werden anhand ausgewählter Ausführungsbeispiele mittels Zeichnungen näher beschrieben. Es zeigen:Further advantageous embodiments of the invention, in particular an arrangement for determining the degree of soiling at least one glass pane section one to a control unit connected vehicle lamp module are based on selected embodiments closer by means of drawings described.
