基于生理信号的驾驶疲劳
声音对策有效性实验

北京工业大学北京交通工程重点实验室, 北京100124

摘要

为了有效减轻驾驶疲劳、减少交通事故,研究了脑电信号(EEG)和心电信号(ECG)随驾驶时间的变化
规律,分析EEG 和ECG 的原始数据与指标之间的相关性,用主成份分析法确定了驾驶疲劳综合评价指标. 采用
正交实验法,在驾驶模拟舱内验证声音刺激作为驾驶疲劳对策的有效性. 研究结果表明:驾驶员在疲劳状态下,
对单一声音刺激存在警觉反应;声强和刺激间隔时间影响显著,频率和刺激时间影响较小,且声强70 dB、频率
5 800 Hz、刺激时间7 s 和刺激间隔时间30 s 的声音对策减轻疲劳的效果最好.

Test on Effectiveness of Sound as Countermeasure
Against Driving Fatigue Based on Physiological Signals

Beijing Key Lab of Traffic Engineering, Beijing University of Technology, Beijing 100124, China

Abstract:

In order to mitigate driving fatigue and reduce traffic accidents, a study on the variation law
of electroencephalograph (EEG) and electrocardiograph (ECG) with driving time was made in a
driving simulator. The correlation between the original data of EEG and ECG and each indicator for
assessing driving fatigue was analyzed, and the overall index of driving fatigue was determined by
principal component analysis. An orthogonal experiment was carried out in the driving simulator cab to
validate the effectiveness of sound stimulus as a countermeasure against driving fatigue. The results
show that drivers in fatigue have an alerting reaction to the single sound stimulus; stimulation interval
and sound intensity have a significant influence on driving fatigue, but stimulation time and sound
frequency have a weak influence on driving fatigue. The best effect in alleviating driving fatigue was
achieved when the sound intensity was 70 dB, the sound frequency 5 800 HZ, the stimulation time
7 s, and the stimulation interval 30 s.

Keywords: driving fatigue   sound countermeasure   driving simulation   EEG   ECG   overall index
