基于驾驶员眼动特征的无极调光智能控制技术的安全性

Safety of Infinitely Dimming Intelligent Control Technology Based on Driver’s Eye Movement Characteristics

为研究采用无极调光智能控制技术对驾驶员行车安全性的影响,选取周公山隧道进行基于驾驶员眼动特征的试验。采用眼动仪记录驾驶员的眼动数据,对注视持续时间、扫视平均速度、瞳孔直径等参数进行统计分析。试验结果表明,驾驶员在使用无极调光智能控制技术的隧道照明环境中行驶时,眼动特征参数与未使用此技术无明显差异,表明驾驶员通过采用此技术的隧道照明环境时,心理舒适程度、紧张程度与未采用此技术的隧道无明显变化,满足了隧道行车安全性、节能性、舒适性的要求。

In order to study the influence of stepless dimming intelligent control technology on driver’s driving safety,the Zhougongshan tunnel was selected to test the eye movement characteristics of the driver.The eye movement data of the driver was recorded by an eye tracker,and the gaze duration,the average speed of the saccade,the diameter of the pupil,and the like were statistically analyzed.The test results show that when the driver is driving in the tunnel lighting environment using the stepless dimming intelligent control technology,there is no significant difference between the eye movement characteristic parameters and the unused technology,indicating that the driver is psychologically comfortable when using the tunnel lighting environment using this technology.There is no significant change in the degree and tension of the tunnels that do not use this technology,and there is no impact on safe driving.
