Abstract

A method and a device are for evaluating sensor signals from a seat mat in a vehicle seat, the signals functioning to characterize the sensors in the seat mat as active and inactive. In this manner, a linear evaluation method is performed to make possible a weight classification of passengers situated on the vehicle seat. For this purpose, a seat profile is generated using the active and inactive sensors.
