ABSTRACT:
An apparatus (34) and associated method are provided for vehicle occupant sensing. An EM energy driver component (36) and associated EM energy source (40) provide a modulated beam (44,e.g., IR light), and a movable reflection component (46) scans the beam onto an occupant location. A detector (92) detects beam reflection and a phase determination component (96) processes phase information that is provided to a controller (24). Within the controller (24) processing (114, 116,and118) provides mapping of occupant contours and determination of an occupant characteristic.
