Abstract
In an occupant detection system, which comprises an electrode arrangement for being placed into the seat of an automotive vehicle, the electrode arrangement including an antenna electrode for emitting an electric field into a detection region above the vehicle seat, and an evaluation circuit operatively connected to the antenna electrode, the evaluation circuit is configured and arranged so as to measure a capacitance influenceable by an occupying item in the detection region through interaction of the occupying item with the electric field. The evaluation circuit is further configured and arranged so as to determine fluctuations of the measured capacitance; analyse a frequency spectrum of the fluctuations; and derive an occupancy state of the vehicle seat based on both the measured capacitance and the frequency spectrum.
