摘要
为探寻"本本族"驾驶人安全行车的驾驶操作,针对光线突变时生理特性的变化展开研究.借助UC-winroad软件和模拟驾驶仪搭建的平台,要求被试者在突发照明场景下进行模拟驾驶试验,同时采用眼动仪、MP150收集驾驶人生理参数.分析能够反映驾驶负荷的脑电信号(α+θ)/β、RR间期平均值和瞳孔面积变化情况,然后建立基于驾驶人脑电波、心率增长率、单次注视持续时间和瞳孔面积变化率在明适应过程中的驾驶负荷模型,以研究不同视觉及生理指标对驾驶负荷的影响程度.研究结果表明:"本本族"驾驶人会对突发照明更快地作出反应,但会产生更大的驾驶负荷,需要更长的适应时间.
Aiming at exploring the carless young drivers＇ safe driving operation, the change of physiological characteristics was taken as an example when the lighting is sudden appearing. By using UC-winroad software and simulation to build the pilot platform, physiological parameters of subjects under the emergency lighting scene are measured, with the eye tracker system and MP150. The changing rate of （α＋θ）/β,mean of RR interphase and pupil area were collected as evaluation index to evaluate driving load. Based on above data,heart rate increase rate and fixation duration, load model was established in the process of light adaptation, which can research the effect of visual and physiological index on pilot stress. The results indicate that carless young drivers will react to emergency lighting faster, but have bigger stress and longer time to adapt.
