Abstract

Procedimiento para el reconocimiento capacitivo de objetos en vehículos, en el que se solicitan dos electrodos de condensador (2, 3) con una tensión alterna (V1, V2) y se percibe la presencia de un objeto (7) por medio de una variación de la capacidad de un condensador, siendo los dos electrodos (2, 3) un componente de respectivos condensadores formados frente a la masa del vehículo y siendo solicitados por separado con dos tensiones alternas (V1, V2) que están en contrafase entre sí, caracterizado porque los electrodos (2, 3) son solicitados por separado con tensiones alternas (V1, V2) del tal manera que se compensen las corrientes alternas (I1, I2) resultantes en las líneas de alimentación (4, 5) de los dos electrodos (2, 3), para lo cual se suman estas corrientes alternas.
