An occupant classification system (OCS) that detects the existence and physique of the passenger seat occupant for the advanced air bag requirements of FMVSS208 was developed. This paper describes an OCS which distinguishes small women (5th percentile adult female dummy: AF05) from young children (less than 6-year-old child dummy: AC06) pertaining to the following items. (1) The reason of classification between AF05 and AC06. (2) The relation between the occupant seating position and OCS output. (3) An influence on the OCS output of the belt tension load and its compensation. This sensor system satisfies the suppression requirements of the FMVSS208. Additionally, other seating positions which Nissan considers important in real world can also be detected. For the covering abstract see ITRD E825082.
