车载全风挡平视显示的驾驶工效影响机理研究

Reasonable information presented by head-up display will help drivers enhance situation awareness level, relieve nervousness and stress, and improve driving safety; otherwise it would lead to distraction, high cognitive load and high safety risk..For the characteristics of high information capacity and diversity of display mode of emerging vehicular full-windshield head-up display, the effects of full-windshield head-up display (FHUD) on driving ergonomics will be investigated. Features of eye movement of drivers when FHUD presenting different information contents and display modes are studied to describe the relationship between the regions of interest of drivers and attention evaluation indexes, and disclose the visual attention allocation mechanism. The effects of information contents and display modes of FHUD on the electrophysiological features of drivers are investigated, the electroencephalogram induced mechanism is clarified, and the information processing mechanism of drivers is disclosed. The movement processes of drivers are investigated when FHUD presenting different information contents and display modes, the correlative mechanism of information perception, processing, and body movement is clarified and the effects of FHUD on behaviors of drivers are revealed..The achievement of this project has great realistic significance and engineering value on improving information presentation of cars and driving safety.

合理的平视显示信息指引可以有效增强驾驶员的情景意识水平、缓解驾驶员紧张和压力情绪、提高车辆驾驶操纵安全性，反之则将导致驾驶员注意力分散、认知负荷过载甚至加剧人机交互安全风险。.针对新兴车载全风挡平视显示信息容量大、显示模式多样的特点，深入研究全风挡平视显示的驾驶工效影响机理：研究不同信息量及显示模式的驾驶员眼动特征，阐明驾驶员视觉兴趣区域与注意力测评指标的关系规律，揭示全风挡平视显示的驾驶员视觉注意力分配机制；研究不同信息量及显示模式的驾驶员脑电信号特征，阐明全风挡平视显示下驾驶员信息加工的脑电诱发机制，揭示全风挡平视显示对驾驶员信息加工的作用规律；研究不同信息量及显示模式的驾驶员静/动态动作特征，阐明全风挡平视显示的驾驶员信息感知-决策-动作关联机制，揭示全风挡平视显示对驾驶员行为绩效的影响机理。.本项目研究成果对改善车辆行驶信息显示模式和提高行驶安全性具有重要现实意义和应用价值。
