    Abstract: A system for interior sensing in a vehicle includes a camera. The camera is configured to capture image data relating to an occupant within a vehicle. The camera is subject to a first coordinate system of the vehicle. The system includes at least one processor configured to identify feature points of the occupant from captured image data and generate raw feature points data. The at least one processor is configured to compensate the raw feature points data with displacement data correlated with a second coordinate system, and generate processed result data. The at least one processor is configured to determine, based on the processed result data, a set of occupant characteristics indicative of behavior of the occupant.

    Abstract: An occupant protection device for protecting an occupant in frontal and oblique crashes. The occupant protection device operates an airbag and switches a load limiting restraint load of the seat belt between a first load limit value and a second lower load limit value. A switching unit switches the restraint load based upon the physique of the occupant, and lateral acceleration or movement of the occupant during an impact. The second load value is set for a small physique occupant. The load value is switched from the first to the second load value after a predetermined time if the lateral acceleration or occupant movement falls below predetermined levels. For a large physique occupant with lateral acceleration or movement exceeding predetermined levels, the load limiter does not switch to the second load value after the predetermined time.

    Abstract: A vision-based vehicle occupant detection and classification system includes a camera mounted in the vehicle interior to capture low resolution images of the seating area. Image processing algorithms account for lighting, motion, and other phenomena. A spatial-feature matrix numerically describes the content of the image. This descriptor is the result of a number of digital filters being run against a set of sub-images, derived from pre-defined window regions in the original image. This spatial-feature matrix is used as an input to an expert classifier function, which classifies this image as best representing a scenario in which the seat is (i) empty, (ii) occupied by an adult, (iii) occupied by a child, (iv) occupied by a rear-facing infant seat (RFIS), (v) occupied by a front-facing infant seat (FFIS), or (vi) occupied by an undetermined object.
