Method for controlling output of a classification algorithm
First Claim
1. A method for controlling output of a classification algorithm which classifies an occupant of a seat in a vehicle, comprising:
- initially classifying the occupant and outputting a current classification;
setting an initial threshold period of time relative to which changes in the current classification are made;
conducting multiple re-classifications of the occupant;
determining a substantially consecutive period of time that the occupant has been classified or re-classified as the current classification;
determining which of the consecutive period of time that the occupant has been classified or re-classified as the current re-classification or the initial threshold is less and setting whichever is less as a comparison threshold;
determining a substantially consecutive period of time that the occupant has been classified differently than the current classification; and
changing the current classification only when the consecutive period of time that the occupant has been classified differently than the current classification is greater than the comparison threshold.

Abstract
Method for controlling output of a classification algorithm which classifies an occupant of a seat including initially classifying the occupant and outputting the classification, subsequently periodically classifying the occupant and enabling a change in the classification of the occupant only upon obtaining evidence of a new classification which is greater than evidence of the current classification. The initial classification of the occupant may be conducted based on satisfaction of a condition such as the detection of closure of a door by, e.g., a sensor such as a door closure sensor, the detection of an empty seat by, e.g., an occupant presence sensor, weight sensor, electric field sensor, wave sensor, camera and the like, the detection of the switching on of the vehicle ignition by an appropriate sensor, motion or the absence of motion of the vehicle.

18. A method for controlling output of a classification algorithm which classifies an occupant of a seat, comprising:
-
initially classifying the occupant and outputting a current classification; conducting multiple re-classifications of the occupant; determining a substantially consecutive period of time that the occupant has been classified or re-classified as the current classification; setting a threshold relative to which changes in the current classification can be made equal to the consecutive period of time that the occupant has been classified or re-classified as the current classification; determining a substantially consecutive period of time that the occupant has been classified differently than the current classification; changing the current classification of the occupant depending on analysis of the consecutive period of time that the occupant has been classified differently than the current classification relative to the threshold; and adjusting the threshold as a function of the consecutive period of time that the occupant has been classified differently than the current classification. - View Dependent Claims (19, 20, 21, 22, 23, 24, 36)

25. A method for controlling output of a classification algorithm which classifies an occupant of a seat in a vehicle, comprising:
-
initially classifying the occupant and outputting a current classification; subsequently periodically re-classifying the occupant; and enabling a change in the classification of the occupant upon satisfying pre-determined criteria; and resetting the classification by classifying the occupant and outputting the classification, upon detection of a condition selected from a group consisting of motion of the vehicle and absence of motion of the vehicle, the step of enabling a change in the classification of the occupant comprising; determining a substantially consecutive period of time that the re-classification of the occupant is the same as the current classification; detecting a change in classification and then determining a substantially consecutive period of time that the re-classification of the occupant is the changed classification; and when the period of time in which the classification is the changed classification is greater than the period of time when the classification is the output classification, or greater than a predetermined time period, outputting the changed classification. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34)

37. A method for controlling output of a classification algorithm which classifies an occupant of a seat in a vehicle, comprising:
-
initially classifying the occupant and outputting a current classification; setting a threshold period of time relative to which changes in the current classification are made; conducting multiple re-classifications of the occupant to obtain a tentative re-classification each time; after each re-classification in which the tentative re-classification of the occupant is the same as the current classification, determining a substantially consecutive period of time that the occupant has been classified or re-classified as the current classification; and after each re-classification in which the tentative re-classification of the occupant is not the same as the current classification, determining a substantially consecutive period of time that the occupant has been classified as the tentative re-classification, and changing the current classification to the tentative re-classification of the occupant only when the consecutive period of time that the occupant has been classified as the tentative re-classification is greater than the lesser of the consecutive period of time that the occupant has been classified as the current classification or the threshold. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44)
