<p>The invention relates to an evaluation method for a seat occupancy sensor of a vehicle seat in order to classify a person sitting on the vehicle seat or an object lying on the vehicle seat. The seat occupancy sensor has several sensor elements distributed over the surface of the vehicle seat. The method comprises the following steps: a) Individual evaluation of individual sensor elements, whereby a measured value is established for each sensor element, said measured value characterizing the instantaneous switching state of the respective sensor element; b) calculating an instantaneous occupancy profile with the use of established measured values; c) comparing the qualities of the instantaneous occupancy profile with a certain number of quality criteria which are stored in a buffer storage and which pertain to previous occupancy profiles; d) recording the instantaneous occupancy profile in a buffer storage if the quality of the instantaneous occupancy profile happens to be better than or equal to the quality of the previous occupancy profiles, whereby the occupancy profile with the lowest quality is deleted from the buffer storage; e) calculating an averaged occupancy profile with the use of the parameters stored in the buffer storage; f) classifying the seat occupancy with the use of the established occupancy profile.</p> |
