Abstract

La présente invention a pour objet un dispositif de détection (D') d'intention de verrouiller ou de déverrouiller une portière (P) d'un véhicule, comprenant : • un premier capteur capacitif comprenant une première électrode (EA), apte à détecter l'approche et/ou le contact d'une partie de corps humain dans une zone prédéterminée (Z2) autour de la poignée (10'), • des moyens de contrôle (MA) dudit premier capteur, générant un premier signal de détection (NA) d'approche et/ou de contact, l'invention proposant : • un deuxième capteur capacitif comprenant une deuxième électrode (EB), apte à détecter l'approche d'une partie de corps humain dans la zone prédéterminée, telle que : - la première électrode (EA) et la deuxième électrode (EB) se présentent chacune sous la forme de segments disjoints et reliés électriquement entre eux, - lesdits segments de la première électrode et la deuxième électrode sont juxtaposés alternativement, • des moyens de contrôle (MB) dudit deuxième capteur, génèrent un deuxième signal de détection (NB) d'approche et/ou de contact, • des moyens de corrélation (MC) calculent une valeur de corrélation entre le premier signal et le deuxième signal, • des moyens de validation (MD) comparent ladite valeur de corrélation avec une valeur prédéterminée afin de détecter l'intention de verrouiller ou de déverrouiller la portière.
