A vehicle system includes a vehicle occupant seat including at least two weight sensors coupled to the seat for generating weight signals. The system further includes an electronic control unit (ECU) including an occupant classification algorithm for generating an occupant classification signal as a function of the weight signals. The electronic control unit further includes variant signal metrics for generating an error signal as a function of comparing the weight signals.

Method and system for detecting occupant seat weight sensor measurement error

The invention is directed to a method for setting an occupant classification system threshold for a vehicle occupant detection system, the method comprising collecting occupant classification system data for a seat, the data being indicative of occupant weight, analyzing the data to determine where a separation exists between an occupant for which a restraint should be suppressed and an occupant for which the restraint should be deployed, and analyzing the data to determine a worst case child suppression weight and shape, which is based at least on where the separation exists. The worst case child suppression weight and shape define the occupant classification system threshold.
