Abstract:
1. A method for discriminating the morphology of a passenger seating in an automotive seat, comprising the steps of i) providing a set of a plurality of capacitive sensors covering substantially a transversal cross section of a seat, ii) collecting the outputs of said plurality of capacitive sensors provided on the seat, iii) determining the morphology of a target facing the seat on the basis of measured distance separating the target from the sensors and measured surface of the sensors covered by the target, from said outputs, by selecting a value representative of the distance (di) separating the target from the sensor, from a look up table, using as input for this selection a combination of the outputs issued by the capacitive sensor and selecting a value representative of the amount (Sdi) of the surface of the sensor covered by said target, from another look up table, using also as input for this selection a combination of the outputs issued by the capacitive sensor, and iv) comparing the determined morphology with at least a reference morphology so as to classify the determined morphology between a plurality of reference morphologies, wherein the comparing step involves a mathematical function of Gaussian type.
