Evaluation Method and Evaluation Device for a System of Seat Occupancy Detection

An evaluation method for evaluating a plurality of reflector responses of a system for seat occupancy detection, wherein the method comprises the following steps:

• (a) detecting a reflected first reflector response, in response to an emitted high frequency signal, of a first area of a seat and a second reflector response of a second area of a seat;
• (b) determining a first decision value from the first reflector response in accordance with a determination rule assigned to the first area and determining a second decision value from a second reflector response in accordance with a determination rule assigned to the second area;
• and
• (c) classifying the determined decision values according to a threshold value rule for the determination of an evaluation result.

An evaluation device for evaluating reflector responses in a system for seat occupancy detection, comprising:

• a detection unit for detecting a first reflector response of a first predetermined area of a seat reflected in response to an emitted high frequency signal, and for detecting a second reflector response of a second predetermined area of the seat;
• a determination unit connected to said detection unit and configured to determine a first decision value from the first reflector response in accordance with a determination rule assigned to the first area and for determining a second decision value from the second reflector response according to a determination rule assigned to the second area;
• and
• a classification device connected to said determination unit for classifying the decision values according to a threshold value rule and for determining an evaluation result derived therefrom.
