CA 2630104

A system and/or method for sensing the presence of moisture (e.g., rain) on a window such as a vehicle window (e.g., vehicle windshield, sunroof or backlite). At least one sensing capacitor (C1, C2, C3, C4) is supported by a window such as a vehicle windshield, the capacitor (s) having a field that is affected by moisture (e.g., rain) on a surface of the window. A sensing circuit outputs an analog signal that is based on and/or related to the capacitance (s) of the sensing capacitor (s). The analog output of the circuit is converted to a digital signal, and subjected to processing (e.g., correlation) for determining whether moisture (e.g., rain, dew, fog, etc.) or the like is present on the surface of the window.

La présente invention concerne un système et/ou un procédé permettant de détecter la présence d'eau de pluie et/ou d'autres matières sur une fenêtre, notamment d'automobile (pare-brise, toit ouvrant, lunette arrière...). Dans certains modes de réalisation particuliers de l'invention, on monte sur une surface fenêtre telle qu'un pare-brise d'automobile au moins un condensateur de détection comportant une zone sensible à l'eau (eau de pluie notamment). Un circuit de détection produit en sortie un signal analogique qui se base sur, et/ou se rapporte à, l'une au moins des capacitances des condensateurs de détection. La sortie analogique du circuit peut être convertie en un signal numérique et soumise à un traitement, notamment une corrélation, pour déterminer s'il y a de l'eau (pluie, rosée, brouillard...) ou analogue sur la surface de la fenêtre.
