Abstract

Procedimiento para el reconocimiento capacitivo de objetos en vehículos, en el que se solicitan dos electrodos de condensador con tensión alterna y se percibe la presencia de un objeto por una variación de la capacidad de un condensador, caracterizado porque los dos electrodos (E1, E2) son solicitados sucesivamente y cada uno por separado con tensiones alternas, y porque se analizan las corrientes alternas que resultan entonces en las líneas de alimentación (4, 5) de los dos electrodos.
