Der Erfindung liegt die Aufgabe zugrunde, eine Regensensoreinheit der eingangs genannten Art derart weiterzubilden, dass Messwerte erfasst werden, die eine Aussage über die Beschlagsneigung der Innenfläche der Kraftfahrzeugscheibe erlauben, wobei aus Gründen der Montageerleichterung möglichst keine zusätzlich zu handhabenden elektrischen Anschlusskabel erforderlich sein sollen und die Anzahl der während der Montage im Kraftfahrzeug zu handhabenden Teile möglichst gering sein soll.Of the Invention is based on the object, a rain sensor unit of further develop the aforementioned type in such a way that measured values are recorded the one statement about the fogging tendency of the inner surface allow the vehicle window, for reasons of ease of assembly preferably no additional should be required to handle electrical connection cable and the number of during the assembly in the vehicle parts to be handled as possible should be low.
Um diese Aufgabe zu lösen ist vorgesehen, dass ein Temperatursensormodul mit dem Gehäuse verbunden ist, wobei die elektrische Versorgung des Temperatursensormoduls über die elektrische Anbindung des optischen Sensors erfolgt, wobei das Temperatursensormodul einen biegesteifen Auslegerarm aufweist, dessen erstes Ende mit dem Gehäuse verbunden ist und dessen freier Endbereich einen zur Kraftfahrzeugscheibe hin ausgerichteten Temperatursensor haltert, wobei der Temperatursensor derart positioniert ist, dass er im eingebauten Zustand gegenüber der Kraftfahrzeugscheibe beabstandet ist. Durch den Anschluss der elektrischen Versorgung des Temperatursensormoduls an die des optischen Sensors kann die Notwendigkeit zusätzlicher elektrischer Anschlusskabel für das Temperatursensormodul vermieden werden. Die Positionierung des Temperatursensors auf dem freien Ende des Auslegerarmes, wobei der Auslegerarm mit dem Gehäuse verbunden ist, ermöglicht die Temperaturmessung der Kraftfahrzeugscheibe in einem vom Regensensor beabstandeten Bereich, wobei durch die Integration an das Gehäuse die Anzahl der während der Montage im Kraftfahrzeug zu montierenden Bauteile nicht erhöht wird. Eine Positionierung in einem definierten und ortfesten Abstand zur Kraftfahrzeugscheibe hat zudem den Vorteil, dass aufgrund des berührungslosen Messprinzips des Temperatursensors eine besonders zuverlässige und genaue Temperaturmessung ermöglicht ist.Around to solve this task it is provided that a temperature sensor module connected to the housing is, wherein the electrical supply of the temperature sensor module on the electrical connection of the optical sensor is carried out, wherein the temperature sensor module a rigid cantilever arm, whose first end with the housing is connected and the free end of a car window pane oriented temperature sensor, wherein the temperature sensor is positioned so that in the installed state against the Vehicle window is spaced. By connecting the electrical Supply of the temperature sensor module to that of the optical sensor may be the need for additional electrical connection cable for the temperature sensor module can be avoided. The positioning of the Temperature sensor on the free end of the boom, wherein the Arm with the housing connected, allows the temperature measurement of the vehicle window in a spaced from the rain sensor Area, whereby by the integration to the housing the number of during the Mounting in the vehicle to be mounted components is not increased. A positioning in a defined and fixed distance to the Vehicle window also has the advantage that due to the non-contact Measuring principle of the temperature sensor a particularly reliable and accurate temperature measurement allows is.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Temperatursensor als ein Thermopile ausgeführt ist, dessen Erfassungsbereich sich kegelförmig in Richtung der Kraftfahrzeugscheibe erstreckt.
