Abstract

Dispositif de détection d'un niveau de liquide (N1, N2) dans un réservoir (2, 3) d'un système d'essuyage de véhicule, en particulier automobile, ledit réservoir étant équipé d'au moins une pompe électrique (21') d'alimentation du système avec du liquide contenu dans le réservoir, caractérisé en ce qu'il comprend des moyens de surveillance du courant consommé par la pompe lors de son utilisation, et de détection d'une chute de consommation de courant de la pompe, significative d'un remplissage partiel en liquide de la pompe et donc d'un niveau de liquide dans le réservoir inférieur à un seuil prédéterminé.
