A METHOD FOR SEAT OCCUPANCY DETECTION FOR AUTOMOBILE SEATS WITH INTEGRATED HEATING ELEMENTS

Abstract:
Seat occupancy detection systems based on a capacitive or an electric field principle, developed for an automobile seat, may not work well for seats with integrated electric heating systems. A new detection method, suitable for this type of automobile seats, is presented in this paper. In the proposed scheme, the heating element is a part of the sensor system while its operation as a heating element is kept unaffected. Results obtained from a prototype system demonstrate the practical validity of the method.
