外部作動型エアバッグのための車の衝突危険領域に関する考察

抄録

An external airbag system in which the airbags deploy outside the vehicle before a collision has been developed. The aim of this system is to reduce impact at collision and to avoid secondary aocidents after collision. The key point in this airbag system is “How to decide that a dangerous collision is about to occur.” For this solution, a collision unavoidable region was proposed by taking a vehicle travel trace into account. In the case of frontal and backside collisions, the decision making of airbag triggering is based not only on sensor information but also on the driver's collision avoidance behavior. On the other hand, in the case of encountering collisions, the corresponding unavoidable region was determined from sensing technologies. Simulation results show the effectiveness of the proposed decision making.
