In an external airbag deployment method, a detection area located in front of a vehicle is set. A target object is selected from among objects detected in the detection area by comparing relative velocities, overlaps, and Time To External Airbag (TTE) values of the detected objects. It is determined whether the vehicle is stable or unstable by comparing a predicted yaw rate of the vehicle with a measured yaw rate. It is determined whether a relative velocity and an overlap of the target object, predicted at a time when the target object is assumed to collide with the vehicle, are greater than predetermined levels. The external airbag is deployed if it is determined that the vehicle is stable and the predicted relative velocity and overlap of the target object are greater than predetermined levels.

SYSTEM AND METHOD FOR CLASSIFYING VEHICLE OCCUPANT

Номер: US20110202311A1

Автор: Young Nam Cho, Yong Sun Kim, CHO YOUNG NAM, KIM YONG SUN

Принадлежит: Kia Motors Corporation

A system and method for classifying a vehicle occupant is disclosed. A base is installed in each of leg frames of a seat of a vehicle. A cover is installed above the base to be spaced apart from the base. Two weight sensors are installed between the base and the cover to support the cover, and configured to measure a load transmitted to the cover by the weight of a vehicle occupant sitting in the seat. A control unit receives load values measured by the weight sensors, and determines whether the vehicle occupant sitting in the seat is an adult or a child based on the received load values. A shock absorption member is interposed between the weight sensors and the base. A stopper is interposed between the base and the cover in order to limit a downward movement range of the cover in a case of overload.
