中文摘要:
      为了探究草原公路交通标志信息量对驾驶员脑电特性的影响,确定最佳信息量水平。本文依据草原公路交通标志现状,利用雷诺六自由度实车模拟驾驶系统模拟典型的草原公路,设计了5个信息量水平(Z1、Z2、Z3、Z4、Z5)的交通标志,其中Z1是草原公路交通标志的主要存在形式。利用MP150多通道生理仪采集驾驶员行驶过程中的脑电信号,探索模拟驾驶环境下驾驶员的脑电信号特征。结果表明:交通标志信息量对驾驶员脑电信号有显著影响,在Z1水平下驾驶员的β波、(α+θ)/β指标表现较差,不利于安全行车;在Z3水平下驾驶员的β波、(α+θ)/β指标表现最佳,最利于安全驾驶;通过对比经验组与非经验组驾驶员,发现经验组驾驶员更放松,经验组驾驶员处理信息的能力要强于非经验组,获取的更多的是有效信息。
英文摘要:
      In order to explore the influence of traffic sign information on the EEG characteristics of drivers, the best information level was determined. According to the current situation of grassland road traffic signs, the driving system of Renault's six DOF real vehicle is used to simulate the typical prairie road, Five traffic signs with information level (Z1, Z2, Z3, Z4, Z5) was designed, among which Z1 is the main form of grassland road traffic signs. Used mp150 multichannel physiological instrument to collect EEG signals during drove, to explore the characteristics of EEG signals of drivers in simulated driving environment.The results show that the traffic sign information has a significant impact on the driver's EEG signal. The β wave, (α + θ) / β index of the driver is poor at the level of Z1, which is not conducive to safe driving; the β wave, (α + θ) / β index of the driver is the best at the level of Z3, which is most conducive to safe driving; By comparing the experience group and the non experience group, we find that the experience group drivers are more relaxed, the experience group drivers are better than the non experience group in information processing ability, and get more effective information.
