Abstract
An improved weight-based occupant characterization method distinguishes between an empty seat and a seat having a small object on it using primary and secondary classification techniques. The primary classification technique is initiated prior to vehicle movement, and characterizes the seat occupant based on measured seat pressure. If deployment of the restraint is suppressed due to the characterization of the primary classification technique, the seat occupancy is characterized by a secondary classification technique based on variation of the measured pressure once the vehicle is in motion. Once the secondary classification technique has characterized the seat occupancy, the characterization of the primary classification technique is discarded in favor of the characterization of the secondary classification technique.
