Abstract:
A capacitive vehicle seat occupancy detection and classification system includes an impedance measurement circuit and a control and evaluation unit. The impedance measurement circuit is configured for providing periodic electrical measurement signals to a capacitive sensor of N different fundamental frequencies, wherein N is a natural number of at least 3, and to determine a complex impedance from each of determined sense currents in the capacitive sensor. The control and evaluation unit is configured to determine a seat occupancy class for each one of the complex impedances determined at the at least N different fundamental frequencies, and to determine a final seat occupancy class derived by a majority decision among the determined seat occupancy classes.

Claim (Index 9):
A method of operating the capacitive seat occupancy detection and classification system as claimed in  claim 1 , including steps of:\n providing a periodic electrical measurement signal of a first fundamental frequency out of the at least N different fundamental frequencies to the capacitive sensor, wherein N equals [(2\u00d7n)+1], with n being a natural number larger than 1 representing the number of potential resonances or electromagnetic (EM) narrowband interferences, determining a complex sense current that is being generated in the capacitive sensor response to the provided periodic electrical measurement signal, determining, with reference to a complex reference potential, a complex impedance from the determined sense current, comparing the determined complex impedance to predetermined threshold values, determining a seat occupancy class for the determined complex impedance, repeating the preceding steps for the balance of the periodic measurement signals of the at least N different fundamental frequencies, and determining a final seat occupancy class by conducting a majority decision among the seat occupancy classes determined for each one of the complex impedances determined at the at least N different fundamental frequencies.
