Abstract
Dispositif de détection du niveau minimal d’un fluide imprimé dans un réservoir La présente invention a pour objet un dispositif de détection d’un seuil de remplissage d’un fluide dans un réservoir (1) d’un véhicule automobile, comprenant un module électronique et un capteur imprimé capacitif (2) de mesure disposé dans le réservoir (1), ledit capteur imprimé (2) comprenant au moins deux zones de mesure correspondant à des niveaux de remplissage différents du réservoir (1), lesdites au moins deux zones de mesure comportant un premier motif sous ledit seuil de remplissage et un deuxième motif au niveau dudit seuil de remplissage, ledit capteur imprimé capacitif (2) étant configuré pour mesurer une première fréquence audit premier motif et une deuxième fréquence audit deuxième motif, ledit module électronique étant configuré pour comparer ladite première fréquence et ladite deuxième fréquence et déterminer si le seuil de remplissage est atteint. (Figure 2)Device for detecting the minimum level of a fluid printed in a reservoir The present invention relates to a device for detecting a filling threshold of a fluid in a reservoir (1) of a motor vehicle, comprising an electronic module and a capacitive printed measurement sensor (2) arranged in the tank (1), said printed sensor (2) comprising at least two measurement zones corresponding to different filling levels of the tank (1), said at least two zones of measurement comprising a first pattern below said filling threshold and a second pattern at said filling threshold, said capacitive printed sensor (2) being configured to measure a first frequency at said first pattern and a second frequency at said second pattern, said electronic module being configured to compare said first frequency and said second frequency and determine if the fill threshold is reached. (Figure 2)
