为了解决目前依靠转向灯识别换道意图时因转向灯开启率低而识别遗漏的问题,探索运用驾驶人在不同任务条件下眼动行为存在的差异来识别换道意图.在真实道路环境条件下进行实车试验,采集了16名驾驶人车辆保持阶段和换道意图阶段的眼动行为数据,运用数理统计方法对比分析驾驶人在不同阶段的基本眼动参数、注意力分配和视觉搜索模式3个方面眼动行为参数.研究结果表明:平均注视时间、平均扫视幅度、车道注意力分配、后视镜注意力分配、仪表盘注意力分配、区域间注视转移概率、水平视觉搜索广度等参数在2个阶段存在显著差异；与车道保持阶段相比,驾驶人在换道意图阶段对目标车道和后视镜的关注明显增加...

In order to solve the problem of low identify rate for identifying lane changing intention relying on turn signal, new identification method for lane changing intention was explored using the difference of 16 driver's eye movement behaviors in different driving tasks. The real-world experiments were conducted to collect driver's eye movements data during lane keeping and lane changing intention stage. Mathematical statistical method was used to analyze eye movement behavior data between different stages, including basic eye movement parameters, attention allocation and visual search patterns. ...
