摘要
为有效提高驾驶员在不良天气条件下的运行安全,针对晴天、中雨、中雨+雾(能见度100 m)和中雨+雾(能见度50 m)4种不同驾驶条件,利用心率变异性(HRV)指标,对驾驶员驾驶工作负荷特性进行研究.通过随机抽取3名驾驶员,在室内进行对于高速公路不同天气场景的仿真实验,对获得的数据进行统计分析发现,驾驶员在不同天气条件下驾驶工作负荷是有差异的,驾驶工作负荷随天气条件的恶劣程度增加,驾驶环境的能见度对驾驶员驾驶工作负荷影响最大.
Weather conditions affect driving safety.Study on the characteristics of the driver workload in bad weather conditions,which can improve the driving safety.A random sample of 3 drivers was tested in a simulator cabin that simulated driving on a freeway under four scenery of weather conditions which are clear day,moderate rain,moderate rain-fog（Visibility 100 m） and moderate rain-fog（Visibility 50 m）.Index of heart rate variability（HRV） is adapted to measure driver workload.We found the driver workload varies in different weather conditions and it is higher with the worse of the bad weather condition.Visibility of the driving environment has the most influence on the driver workload.
