Vehicle occupant restraint with seat pressure sensor

摘要

The method involves measuring a pressure response of each sensor, followed by calculating a total occupant weight. A weight distribution parameter is further calculated for distinguishing between adult and occupied infant seat presence on the basis of total occupant weight. The method also entails distinguishing between forward facing and rear facing infant seats on the basis of the weight distribution parameter. Further the method includes determining whether to inhibit deployment on the basis of adult presence, and on presence and position of an infant seat. E.g. establishing a reference line is performed in relation to the sensors which form a forward weight distribution indicative of a rear facing infant seat.
