摘要

为提升平头车保护人体头部损伤的能力和法规上的接受水平，通过推导车头伸出长度公式而给出一种使平头车变长头车的方法，随后通过理论和仿真分析研究所提方法的损伤防护效果及摩擦系数、车速和行人身高等因素对防护效果的影响规律。结果显示：所提方法能极显著降低行人头部损伤，且在低速、低摩擦、矮行人身高下防护效果更佳。分析发现伸出可变车头长度优于固定车头长度，而在获得更高精度行人损伤风险曲线后可进一步优化所提方法。该研究将为M类、N类等大型平头车辆保护行人提供新思路，为它们利用长头车智能安全技术以更好地保护行人提供支持。

Abstract

In order to improve the ability of flat-front vehicles to protect human body head injuries in pedestrian-vehicle collisions and the level of regulatory acceptance, a method to change the flat-front vehicle into a bonnet-front one is proposed by deducing the formula of the protruding length of the front-end. Then the injury protection effect of the proposed method and the influence of factors such as friction coefficient, vehicle speed and pedestrian height on the protection effect are studied by theoretical and simulation analysis. The results show that the proposed method can significantly reduce pedestrian head injury, and the protective effect is better at lower speed, lower friction and shorter pedestrian height. It is found that variable front-end length is better than fixed front-end length, and the proposed method can be further optimized after obtaining higher precision pedestrian injury risk curve. This study will provide new ideas for the protection of pedestrians by large vehicles such as Class M and Class N, and provide support for them to better protect pedestrians by using intelligent safety-related technologies of bonnet-front vehicles.
