Abstract

L'invention concerne un dispositif de détection capacitive d'approche (10) pour interface utilisateur (1) destiné à détecter l'approche d'un objet vers une zone de commande (12) d'une façade (11) du dispositif de détection d'approche (10) caractérisé en ce qu'il comporte en outre au moins deux électrodes (14, 15 ; 24, 25) espacées l'une de l'autre et portées par la façade (11) de manière que la détection de l'approche d'un objet dans le champ de détection des électrodes (14, 15 ; 24, 25) puisse être prise en compte en fonction de la comparaison des signaux capacitifs (S1, S2) des deux électrodes (14, 15 ; 24, 25). L'invention concerne également une interface utilisateur (1) pour véhicule automobile et un procédé de détection capacitive d'approche (100) d'un objet vers un organe de commande (2) d'une interface utilisateur (1).The invention relates to a capacitive approach detection device (10) for a user interface (1) for detecting the approach of an object to a control area (12) of a facade (11) of the detection device. approach (10) characterized in that it further comprises at least two electrodes (14, 15; 24, 25) spaced from one another and carried by the facade (11) so that the detection of the approach of an object in the detection field of the electrodes (14, 15; 24, 25) can be taken into account according to the comparison of the capacitive signals (S1, S2) of the two electrodes (14, 15; 24 , 25). The invention also relates to a user interface (1) for a motor vehicle and to a method for capacitive detection of the approach (100) of an object to a control member (2) of a user interface (1).
