Also, the upper reversal point OT may be adjusted depending on the speed.

Abstract

L'invention concerne un procédé servant à faire fonctionner un système d'essuie-glace (100) servant à nettoyer une vitre (1) de véhicule. Le système d'essuie-glace (100) comporte un balai d'essuie-glace (2), qui est déplacé au moins indirectement au moyen d'un moteur (10) d'essuie-glace entre deux points d'inversion (UT, OT) le long de la vitre (1) de véhicule. Le déplacement entre les deux points d'inversion (UT, OT) constitue un cycle de lavage. Le nombre des cycles de lavage définit une fréquence de lavage (f) pendant un laps de temps prédéfini. L'invention prévoit que la fréquence de lavage (f) passe d'une première fréquence de lavage (f1) sur une deuxième fréquence de lavage (f2) conformément à une fonction (g1, g2, g3, g4) prédéfinie en fonction d'une vitesse (v) de véhicule.
