A method of controlling an airbag inflator, may include determining, when an occupant is accommodated on a seat, whether the weight of the occupant is in which of first to fourth weight ranges sequentially allocated by a controller, performing a first logic for operating an inflator at the lowest one of three intensities by the controller when it is determined that the weight of the occupant is in the lightest first weight range, and performing a second logic for operating the inflator at the intermediate intensity or a third logic for operating the inflator at the highest intensity by the controller, according to conditions such as a position of a seat, a state of operation of a recliner, a collision condition, a collision pulse, and wearing of a belt, when it is determined that the weight of the occupant is in the third or fourth weight range.

A passenger protection apparatus for a vehicle includes first and second airbags, an airbag deployment device, a collision speed detector, a passenger's position detector, a seat moving unit, an airbag deployment determination unit, and a deployment controller. The first airbag is deployable in different sizes. The second airbag is deployable between the first airbag and vehicle equipment. The airbag deployment device deploys the airbags. The collision speed detector detects a collision or collision possibility of a vehicle, and calculates a collision speed. The passenger position detector detects a position of a passenger sitting on a seat. The seat moving unit moves the seat. The airbag deployment determination unit determines a size of the deployed first airbag. The deployment controller determines an amount of movement of the seat, causes the seat moving unit to move the seat, and causes the airbag deployment device to deploy the airbags.

Method for analyzing a crash event. The method may comprise receiving an acceleration of a vehicle over a predetermined length of time, the vehicle involved in the crash event, determining a change in velocity of the vehicle based on the acceleration, determining vehicle information relating to the vehicle involved in the crash event, and estimating a damage cost for the vehicle involved in the crash event, and/or estimating injuries to occupant(s) of the vehicle involved in the crash event. Estimating damage cost(s) may include determining crash force information for the vehicle, determining physical-damage characteristics of the vehicle subsequent to the crash event, and calculating the estimated damage cost to the vehicle. Estimating injuries to the occupant(s) may include determining occupant information relating to the occupant of the vehicle, calculating estimated forces exerted on the occupant, and calculating an injury probability for various body portions for the occupant.

A computer-implemented method is provided for predicting occupant location based on vehicular collision. The method includes receiving, at a computing system including one or more processors, information indicative of a vehicle crash involving a vehicle occupant. The method also includes receiving, at the computing system, information indicative of a position of the vehicle occupant within the vehicle prior to the vehicle crash. The method also includes determining, by the one or more processors, a probability of ejection of the vehicle occupant according to (i) the information indicative of the vehicle crash and (ii) the position of vehicle occupant. The method also includes providing, by the computing system, the probability of ejection of the vehicle occupant to one or more emergency responders.

Systems and methods may predict location of a vehicle occupant in the event of a collision involving the vehicle and another entity. Information indicative of a posture of the occupant prior to the collision may be obtained based on information from one or more image sensors of the vehicle. Systems and methods determine whether one or more conditions corresponding to an increased likelihood of ejection of the occupant are present, based on the posture. The systems and methods further may automatically generate and provide a visual notification to a device of a responder, the visual notification indicating that the increased likelihood of ejection of the occupant is present, as well as a location of the occupant.
