摘　　要：为找出午餐前后驾驶人疲劳特征变化规律,选取6名驾驶人开展了驾驶模拟试验。对驾驶人午餐前后的体温、心率变异性、深度知觉、速度知觉等生理、心理特征参数进行了测定,并通过问卷方式获取了驾驶人对自身疲劳状况的主观感受,分析了午餐前后驾驶疲劳特征的变化。生理参数分析结果表明：驾驶人心率变异性指标在午餐后1~1.5 h内呈升高趋势,随后下降至正常水平;体温指标在午餐后出现一个低谷,随后恢复正常;PERCLOS指标值午餐后均有所增大,其中67%受试者PERCLOS值增幅明显。心理特征参数变化表明：午餐后受试者认知能力出现了不同程度的降低,主要体现为深度知觉能力下降、反应时间延长和速度判断力下降。这些都将影响驾驶人对道路环境信息的获取,进而会增加驾驶不安全因素。In order to analyze the variation of the driver fatigue characteristics,6 drivers were selected to carry out driving simulation experiments,and the indices of physiology and psychology,such as body temperature,heart rate variability,depth perception,speed perception,were recorded at the same time.And the results of self-evaluation about fatigue were gotten by questionnaire,and the driving fatigue characteristics changes of drivers before and after lunch were analyzed.The analysis results of physiological indices show that heart rate variability（HRV） index of drivers tends to increase after lunch about 1~1.5 hours,then decreased to normal levels;body temperature will decrease to a low level after lunch and then return to normal;PERCLOS index value increase occur on all drivers,of which 67% PERCLOS value increases dramatically obvious.Changes in indices of psychological characteristics show that,after lunch,the driver＇s cognitive abilities decrease,mainly reflected in decrease of ability in depth perception,reaction time and speed perception,these will affect the drivers＇ getting road environmental information,thereby increasing insecurity of driving behavior.4 tabs,4 figs,11 refs.
