The invention relates to the technical field of automobile passive safety protection, in particular to an intelligent airbag engine hood for protecting pedestrians and a working method thereof.The intelligent airbag engine hood is sequentially composed of a supporting layer, a sensing layer, an airbag layer and a protective layer. A middle airbag can be wound around or grabbed by a hit person to effectively prevent the hit person from flying out to be injured; if the middle airbag is not wound around or grabbed by a hit person, the engine hood sensing layer monitors the position of the hit person in real time, and it can be guaranteed that when a pedestrian suffers collision by a vehicle, through contact between the hit person and the airbag and movement of the vehicle, inertia energy of impact borne by the hit person is reduced, so that impact force on the ground caused by final falling of the vehicle is reduced, the used technology is mature and reliable, and the engine hood is suitable for large-scale application and popularization, has practical significance and popularization value and is expected to generate good economic benefits.
本发明涉及汽车被动安全保护技术领域,具体为一种保护行人的智能气囊发动机罩及其工作方法,本发明提供的智能气囊发动机罩,其依次由支撑层、感知层、气囊层和保护层构成,通过中部气囊能缠绕或者被被撞者抓住可以有效地避免被撞者飞出去所受到的伤害,如果未缠绕或者被抓住,有发动机罩感知层实时监控被撞者位置,能够确保行人被车辆撞击利用被撞者和气囊的接触和汽车的移动,减小被撞者所受冲击的惯性能量,从而减小最后跌落汽车对地面的冲击力,所用技术成熟可靠,适合大范围推广使用,具有实用意义和推广价值,预期能够产生良好的经济效益。
