摘要

An occupant detection system (10) incorporates a radar range sensor (12) adapted to sense the position of an occupant (15) in a vehicle (21). The activation of the radar range sensor (12) is responsive to the proximity of the occupant (15) to a restraint actuator (39), or to an occupant sensor (200) adapted to sense the presence or position of the occupant on a seat (17). The radar range sensor (12) is disabled and the restraint actuator (39) is enabled responsive to an occupant (15) seated proximate to the seat back (46) as sensed by a range/proximity sensor (222). The radar range sensor (12) is disabled and the restraint actuator (39) is disabled responsive to an infant or child (602) in and infant or child seat (600) on the vehicle seat (17) sensed by an electric field sensor (100) or a seat weight sensor (224). The radar range sensor (12) is enabled and the restraint actuator (39) is controlled responsive thereto if the occupant (15) is on the seat (17) but not proximate to the seat back (46).
