摘要
为探究自动紧急制动(automatic emergency braking,AEB)系统与主动预紧安全带在发生正面碰撞时的防护效果,基于某车型构建了 AEB功能和主动预紧安全带的乘员约束系统模型;对3组不同防护策略(无AEB无预紧安全带、有AEB无预紧安全带和有AEB有预紧安全带)开展了正面100％重叠刚性壁障碰撞仿真实验.仿真结果表明:仅有AEB作用下,乘员平均加权伤害指标(weighted injury criteria,WIC)值反而升高了 79％;而在AEB和主动预紧安全带耦合作用下,乘员平均WIC值降低了 9％.在主动预紧安全带与AEB系统联合作用下,能够有效提高乘员防护水平.
Abstract
In order to investigate the protection effect of automatic emergency braking(AEB)system and active pre-tensioner seat belts in frontal collision,an occupant restraint system model with AEB function and active pretensioner seat belts was constructed based on a certain car model;frontal 100％overlapping rigid barriers collision of simulation experi-ments were carried out for three groups of different protection strategies(without AEB and no pretensioner seat belts,with AEB and no pretensioner seat belts,and with AEB and pretensioner seat belts).The simulation results show that the average Weighted Injury Criteria(WIC)value of the occupants increased by 79％with AEB only,while the average WIC value of the occupants decreased by 9％with the coupled effect of AEB and active pretensioner seat belts.With the active pre-tensioning seat belts in combination with the AEB system,the level of occupant protection can be effectively im-proved.
