Abstract

L'invention concerne un système de détecteur (10) destiné à être utilisé, de préférence, dans un système de déploiement de coussin gonflable pour véhicule, et faisant intervenir des techniques d'ombrage spatial et l'analyse centroïde pour calculer une charge ponctuelle équivalente dans un espace à deux dimensions. On utilise l'emplacement correspondant à la charge ponctuelle équivalente ainsi que le poids des passagers relevé par les détecteurs (S1- S6) pour calculer un ensemble de limites selon la logique floue, ensemble qui définit différents modes de déploiement du coussin gonflable. Lesdites limites établies selon la logique floue peuvent comprendre des zones de déploiement total, partiel, nul et autres degrés de déploiement intermédiaires. En cas d'incident, le coussin gonflage se déploiera en fonction de la limite, établie par logique floue, dans laquelle se trouvent le poids et la charge ponctuelle équivalente de l'occupant du véhicule.
