摘　　要：研究疲劳驾驶时的脑电特性.利用汽车模拟驾驶系统模拟驾驶员疲劳驾驶的情况,用脑电仪记录驾驶员的脑电情况,得到了驾驶员在正常状态和疲劳状态下驾驶时的脑电数据和波形,分别用平均功率谱方法和非线性的关联维数方法对所得数据进行分析.得到了疲劳驾驶时脑电的2个特征量R和D.可以用驾驶员驾驶时的脑电特征量来评价其疲劳程度.To investigate the characters of the electroencephalogram （EEG） for fatigued drivers, the situation of fatigue driving was simulated using a car simulator, the EEG for the driver was recorded by an EEG recording instrument, and the EEG data and waves obtained. Methods of average power spectrum and correlation dimension were applied to analyze these data. Characters R and D in the EEG for the fatigued driver were found. The degree of fatigue of the driver can be estimated by the characters shown by the EEG.
