摘要
在分析了驾驶员期望车速的主要应用及其影响因素的基础上,对影响驾驶员期望车速的因素进行了单因素测试实验设计,建立了模拟实验所需的3维虚拟实验场景.选择了16名受试者进行了模拟驾驶实验,对实验数据进行了统计分析,分析结果表明影响驾驶员期望车速的3个主要因素为车道数、车道宽和路肩宽.分别建立了车道数、车道宽、路肩宽与期望车速的关系模型,并在期望车速模拟实验研究的基础上,构建了驾驶员期望车速的预测综合模型,给出了模型的修正系数及其取值表.
On the basis of analysis of the forming process and the influencing factors of driver＇s desired speed,the single- factor simulation experiments are designed,and the three- dimensional scene model is established.16 subjects are selected to participate in the experiments and a statistical analysis is then made using the experimental data. The analysis result shows that the desired speed is mainly influenced by the lane number,lane width and shoulder width. The functions between desired speed and lane numbers,lane width,the shoulder width are respectively regressed. Finally,the integrated desired speed model is built based on the research of the simulation experiment. The correction coefficients of the model are explained thereafter.
