Abstract
Predetermined multiple points of the front passenger seat and its periphery are irradiated with spot beams, caught with a camera, and distances are measured based on the irradiation position of the spot beams. Conversely, the characteristics for each status of use of the seat such as the shapes of the contour of the seat or the contour of a child seat are detected from the picture information caught with the camera. The status of use of the seat is decided based the characteristics for each status of use and the distance information that was previously measured. Based on this decision, the operation of a passive safety device such as an air bag device is controlled.
