Method for the classification of an occupancy status of a vehicle seat
First Claim
1. A method for the classification of an occupancy status of a vehicle seat, wherein a filtered class is associated to a specific seat occupancy status based on a plurality of successive readings of at least one parameter value of a seat occupancy sensor, said method comprising the steps of:
- a. determining an actual value of a first parameter of said seat occupancy sensor and associating an actual class to said actual value of said first parameter, b. storing said actual class in a buffer comprising several previously determined classes;
c. plotting a confidence parameter, said confidence parameter being indicative of the reliability of the actual class; and
d. setting said filtered class to equal i) an average of the classes stored in said buffer, if said confidence parameter is smaller than a first confidence threshold value; and
ii) a previously determined filtered class, if said confidence parameter is greater than said first confidence threshold value.

Abstract
A method for classifying an occupancy status of a vehicle seat includes associating a filtered class to a specific seat occupancy status based on a plurality of successive readings of at least one parameter value of a seat occupancy sensor, including the steps of: 1) determining an actual value of a first parameter of the seat sensor and associating an actual class to the actual value of the first parameter; 2) storing the actual class in a buffer, and deleting the oldest stored class; 3) plotting a confidence parameter indicative of the reliability of the actual class; 4) setting an updated filtered class to equal (i) an average of the classes stored in the buffer, if the confidence parameter is smaller than a first confidence threshold value, or (ii) the previously determined filter class, if the confidence parameter is greater than or equal to the first confidence threshold value.
