Abstract
An occupant sensing system for a vehicle includes a pressure sensitive material installed in one or more pressure sensing zones in or around at least one vehicle seat. The pressure sensitive material of each zone is configured to provide an electrical signal to a controller when pressure is applied. The controller determines at least one of occupant presence, position, and classification based on the electrical signal. The pressure sensitive material has at least one of a variable resistance and a variable capacitance based on the amount or type of pressure that is applied to the material. The at least one of a variable resistance and a variable capacitance changes characteristics of the electrical signal.
