The primary function of the Occupant Classification System is to provide reliable passenger seat occupancy information to the automobile’s central processing unit to control airbag deployment. Our Occupant Classification (OC) sensor system is based on analysis of the seat occupancy pressure profile, which discerns human like from human unlike profiles. If the occupancy is identified as a person, an allocation into one of four morphologic ranges is made. Accordingly, children, light adults, heavy children, medium adults, heavy adults, etc. can be discerned (Figure 1).
