摘要:
为明确海底隧道纵坡坡度变化对驾驶人脑电信号的影响，通过开展实车实验，运用脑电仪、坡度记录仪及录像机等设备，采集车辆通过海底隧道变坡区时，驾驶人的脑电信号及海底隧道纵坡坡度数据．选取脑电信号功率谱与脑电功率为参量，分析驾驶人经过海底隧道变坡区时脑电信号活跃水平的变化规律；按照不同上下坡对变坡区进行分组，分别建立海底隧道纵坡坡度变化与脑电信号β波功率变化的数学模型．结果表明，驾驶人在经过变坡区时，大脑活跃水平明显提升，额叶区是对纵坡坡度变化最敏感的脑区；纵坡坡度变化与驾驶人脑电信号β波功率变化正相关，纵坡坡度变化越小，脑电信号β波功率变化越小，驾驶人心理压力越小，行车安全性越好．
Abstract:
In order to clarify the impact of changes in the longitudinal slope of undersea tunnel on the driver’s electroencephalography (EEG) signal, real vehicle experiments are carried out, using EEG instrument, gradient recorder, video recorder and other experimental equipments to collect data, such as driver’s EEG and the data on the longitudinal slope of the undersea tunnel. The EEG power spectrum and EEG power are selected as parameters, and the EEG signal change law is analyzed when the driver passes through the undersea tunnel’s slope change area; the slope change areas are grouped according to the difference of the up and down slopes, and the mathematical models of the longitudinal slope change and the change of EEG β wave power have been established respectively. The study results show that the brain activity level of drivers increases significantly when passing through the gradient zone; the frontal area is the brain area which is most sensitive to the changes in longitudinal slope; the longitudinal slope and its change are positively correlated with the change of the driver’s EEG β wave power. The smaller the longitudinal slope, the smaller the EEG β wave power change; the lower the driver’s psychological pressure, the better the driving safety.
