Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Vorrichtung und ein verbessertes Verfahren zur Ermittlung eines Verschmutzungsgrades eines Luftfilters eines Fahrzeugs anzugeben.The invention has for its object to provide an improved device and an improved method for determining a degree of contamination of an air filter of a vehicle.
Die Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung zur Ermittlung eines Verschmutzungsgrades eines Luftfilters eines Fahrzeugs mit den Merkmalen des Anspruchs 1 und ein Verfahren zur Ermittlung eines Verschmutzungsgrades eines Luftfilters eines Fahrzeugs mit den Merkmalen des Anspruchs 9.The object is achieved by a device for determining a degree of contamination of an air filter of a vehicle having the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Bei einer Vorrichtung zur Ermittlung eines Verschmutzungsgrades eines Luftfilters eines Fahrzeugs weist der Luftfilter erfindungsgemäß eine Schicht mit einem lumineszenten Stoff auf. Die Vorrichtung umfasst erfindungsgemäß des Weiteren eine Lichtquelle, die Licht mindestens einer Wellenlänge, die Lumineszenz in der Schicht anregt, aussendet, und einen Detektor zur Bestimmung einer Intensität eines durch die Schicht abgestrahlten Lumineszenzlichtes.In an apparatus for determining a degree of contamination of an air filter of a vehicle, the air filter according to the invention comprises a layer with a luminescent substance. According to the invention, the device furthermore comprises a light source which emits light of at least one wavelength, which excites luminescence in the layer, and a detector for determining an intensity of a luminescent light emitted by the layer.
Die Vorrichtung ermöglicht eine exakte und automatische Erkennung des aktuellen Verschmutzungsgrades des Luftfilters, da bei einem hohen Verschmutzungsgrad die Schicht mit dem lumineszenten Stoff durch Ablagerungen bedeckt ist, so dass die Intensität des durch die Schicht abgestrahlten Lumineszenzlichtes wesentlich verringert ist. Dies ermöglicht eine Optimierung eines Wechselrhythmus des Luftfilters, d. h. einen Austausch des Luftfilters zu einem Zeitpunkt, an welchem dieser Austausch erforderlich ist. Dadurch sind sowohl ein mit hohen Kosten verbundener vorzeitiger Austausch als auch ein durch starke Verschmutzungen aufgrund eines zu späten Austauschs unwirksamer Luftfilter zu vermeiden.The device enables an exact and automatic detection of the current degree of contamination of the air filter, since at a high degree of contamination, the layer with the luminescent substance is covered by deposits, so that the intensity of the luminescent light emitted through the layer is substantially reduced. This allows an optimization of a cyclic rhythm of the air filter, d. H. an exchange of the air filter at a time when this replacement is required. This avoids both high-cost premature replacement and heavy contamination due to late replacement of ineffective air filters.
