摘　　要：为研究先进驾驶辅助系统下驾驶人面对交通场景中突发事件的应激反应能力,利用自主开发的应激反应能力测试软件,通过设置场景风险提示来模拟先进驾驶辅助系统的引导作用。选取操作准确率、反应时间和额外反应次数为测试指标,测试不同信息引导方式下驾驶人的应激反应能力。运用认知评价理论调查被试对测试软件和试验的主观感受。结果表明,视觉、听觉和视听觉引导均能有效提升驾驶人的应激反应能力,缩短应激反应时间;视觉和视听觉引导比听觉引导效果更好;有信息引导的驾驶人额外反应次数较少;驾驶人应激反应能力能够通过训练和心理激励获得提升。In order to study ability of drivers to respond to emergencies under situations with Advanced Driver Assistance System,self-developed software for testing emergency response is used to simulate guidance role of Advanced Driver Assistance System by setting risk alerts.Operation accuracy,reaction time,and extra reactions are selected as test indicators to measure emergency response ability of drivers under different guidance methods.Subjective feelings of the drivers to testing software and the test are investigated by cognitive evaluation theory.The results show that visual,auditory,and visual-auditory guidance can effectively improve emergency response ability and shorten response time.Visual and visual-auditory guidance are better than auditory guidance.Drivers with guidance have fewer extra reactions.Emergency response ability can be improved through training and psychological stimulation.
