摘　　要：为了避免在视觉障碍紧急工况下车辆碰撞行人事故的发生,针对存在视觉障碍的典型车辆-行人自动紧急制动(AEB)测试场景,提出了3种具有不同碰撞时间(TTC)和制动减速度的AEB触发策略(保守型、法规型、激进型),在2起典型视觉障碍事故场景条件下,基于PreScan、MATLAB/Simulink、CarSim等仿真平台建立事故场景和车辆动力学模型,并搭建AEB策略模型,对比分析3种AEB触发策略的制动有效性。结果表明:所搭建的AEB模型均能在典型行人碰撞场景中实现避撞,其中法规型制动策略规避效果最佳。To avoid the incidence of vehicle-pedestrian collision accidents under emergency scenarios involving visual impairments,this study focuses on typical vehicle-pedestrian Automatic Emergency Braking(AEB)test scenarios with visual impediments.Three AEB triggering strategies,namely the conservative,regulatory,and aggressive strategies,are proposed,each characterized by distinct Time to Collision(TTC)values and braking deceleration profiles.Under the circumstances of two prototypical accident scenarios with visual impairments,accident scenarios and vehicle dynamics models are constructed using simulation platforms such as PreScan,MATLAB/Simulink,and CarSim.Subsequently,an AEB strategy model is developed.A comparative analysis is then conducted to evaluate the braking effectiveness of the three AEB triggering strategies.The results show that all the AEB models in this study can achieve collision avoidance in typical vehicle-pedestrian accident scenarios,with the regulatory braking strategy having the best avoidance effect.
