Abstract
An improved weight-based occupant characterization method reliably distinguishes between an empty seat and a seat occupied by an ultralight child seat. The seat occupancy is initially characterized using a primary classification technique in which the measured seat pressure is compared to an allow threshold representative of a minimum weight adult. If the primary classification technique determines that the seat is empty and a seat belt for the passenger seat is buckled, a secondary classification technique is initiated to compare the measured seat pressure to a predetermined pressure range characteristic of occupied ultralight child seats. If the measured pressure falls within the ultralight child seat range, characterization of the primary classification technique is discarded in favor of the characterization of the secondary classification technique.
