团雾环境驾驶人最低注意力需求研究综述

Review of the Minimum Attention Demand of Drivers in Environment of Dumpling Fog

团雾环境下驾驶人生理心理的相关研究一直是一个亟待解决的行业难题。为了提升团雾环境行车安全性,明确团雾环境中驾驶人最低注意力需求,综述了国内外低能见度条件下驾驶人注意力的相关研究进展。首先,阐述了驾驶人注意力特性,明确了团雾环境对驾驶人注意力的主要影响因素,讨论了相关的研究方法和数学模型;其次,分析了车辆行驶速度与能见度对驾驶人最低注意力需求的影响,阐明了视觉生理负荷与驾驶人最低注意力需求之间的联系;最后,进行了团雾环境对驾驶人最低注意力需求影响耦合分析,根据行驶车辆经过团雾路段所处不同时空进行划分。通过剩余注意力的变化,分析了团雾环境中能见度、速度与最低注意力需求之间的动态变化关系,建立了车辆通过团雾路段过程中驾驶人最低注意力需求突变的理论模型。通过归纳总结现有团雾环境的研究,发现目前在驾驶人诱导需求方面有所欠缺。在后续的研究中,考虑团雾环境对驾驶人的多因素影响,选择更能反映驾驶人视觉心理需求的评价指标进行量化分析,将会成为主要的目标。

The research on driver’s physiology and psychology in foggy environment has always been an pressing industry problem to be solved.In order to improve the driving safety in dumpling fog environment and clarify the driver’s minimum attention demand in dumpling fog environment,the research progress of driver’s attention under low visibility conditions at home and abroad was reviewed.Firstly,the characteristics of driver’s attention was expounded,the main influencing factors of fog environment on driver’s attention was clarified,and the relevant research methods and mathematical models was discussed.Secondly,the influence of vehicle speed and visibility on driver’s minimum attention demand was analyzed,and the relationship between visual physiological load and driver’s minimum attention demand was clarified.Finally,the coupling analysis of the influence of the fog environment on the driver’s minimum attention demand was carried out,which is divided according to the different time and space of the driving vehicle passing through the dumpling fog section.Through the change of spare capacity,the dynamic relationship between visibility,speed and minimum attention demand in the dumpling fog environment was analyzed,and then a theoretical model of the minimum attention demand mutation of the driver during the vehicle passing through the dumpling fog section was established.By summarizing the existing research on the dumpling fog environment,it is found that there is a lack of demand for driver induction.In the subsequent research,considering the multi-factor influence of the fog environment on the driver,selecting the evaluation index that can better reflect the driver’s visual psychological demand for quantitative analysis will become the main goal.
