摘要: 为开发高速公路驾驶疲劳预警系统,保障道路交通安全,基于脑电(EEG)数据功率谱分析方法,探索驾驶员主动疲劳与脑电指标(θ+α)/β的关系,首先,开展模拟驾驶试验,采集21名被试驾驶状态的脑电信号,分析α(8~13 Hz),β(13~30 Hz),θ(0.5~4 Hz)这3个频段的脑电波,计算脑电合并指标(θ+α)/β;然后,运用瑞典行业疲劳问卷(SOFI),比较驾驶员执行驾驶任务前后的疲劳状态,分析心理测量和脑电测量结果的回归拟合效度。结果表明:在高速公路复杂驾驶任务中,驾驶员脑电合并指标(θ+α)/β呈现下降趋势,同时,(θ+α)/β与驾驶员主观疲劳程度有显著的正向拟合关系,拟合解释率达50%;脑电指标(θ+α)/β可实时预测驾驶员主动疲劳状态。

Abstract: To develop a system for warning the expressway driving fatigue and ensure road traffic safety, this study was aimed at exploring the relationship between EEG indicator (θ+α)/β and driver's active fatigue based on EEG data power spectrum analysis. EEG indicator (θ+α)/β was calculated by assessing three frequency bands: alpha (8-13 Hz), beta (13-30 Hz) and theta (4-8 Hz), during a simulated driving session in 21 subjects. SOFI scale was adopted to analyse fitigue state before and after driving, and regression method was used to examine the fitting validity of psychological measures and EEG algorithm (θ+α)/β.The results show that there is a negative correlation between the (θ+α)/β activity and time, that there is a positive correlation between EEG indicator (θ+α)/β and the driver's active fatigue, and the fitting interpretation rate is 50%, and that the EEG indicator (θ+α)/β is able to predict active fatigue in real time.
