Abstract

L'invention propose un procédé de commande d'un système d'essuyage de la surface extérieure d'une vitre (10) de véhicule automobile ayant subi au moins un traitement hydrophobe, système qui comporte un bras (31) d'entraînement d'un balai d'essuie-glace (30) qui coopère avec la vitre (10), et un capteur de mesure d'un paramètre permettant d'estimer le degré d'hydrophobie de la surface extérieure (11) de la vitre (10), et un circuit (60) de commande de la vitesse de balayage qui modifie la vitesse de balayage en fonction de variations dudit paramètre. Selon le procédé, le degré d'hydrophobie de la surface extérieure (11) de la vitre (10) est estimé par le circuit de commande (60) en fonction d'un paramètre représentatif du coefficient de frottement entre le balai d'essuie-glace (30) et la surface de la vitre (10).The invention provides a method for controlling a system for wiping the exterior surface of a window (10) of a motor vehicle having undergone at least one hydrophobic treatment, system comprising a drive arm (31) for a wiper blade (30) which cooperates with the window (10), and a sensor for measuring a parameter making it possible to estimate the degree of hydrophobicity of the external surface (11) of the window (10) , and a scanning speed control circuit (60) which changes the scanning speed in accordance with variations of said parameter. According to the method, the degree of hydrophobicity of the exterior surface (11) of the window (10) is estimated by the control circuit (60) as a function of a parameter representative of the coefficient of friction between the wiper blade. glass (30) and the surface of the glass (10).
