在这项研究中，我们特别考虑了由于使用具有 ACC 和 LKA 功能的半自动驾驶辅助系统而导致的唤醒水平降低。 10 young men took part in the experimental study using a driving simulator.平均10人，系统启用时睡意量表达到4级或以上（1级：看起来一点也不困，5级：很困）的参与者比例比系统禁用时增加了34%。对视觉刺激的反应时间明显延迟，并且在困倦评定量表中达到 4 级或以上时，存在显着差异。我们认为，应该对实际驾驶（FOT；现场操作测试）进行持续的长期调查来验证本研究的结果。我们还分析了闭眼率与困倦评定量表之间的关系，并确认闭眼率值为 0.26 对应于困倦量表的 4 级，其中反应时间明显延迟。根据这些发现，人们相信可以设计一种设备来根据眼睛闭合率来检测唤醒水平。
In this study, we specifically considered decrease in arousal level stemming from using semi-autonomous driver assistances featuring ACC and LKA functions in operation. 10 young men took part in the experimental study using a driving simulator. For an average of 10 people, the participant rate for those who reached level 4 or above (level 1; Seems not sleepy at all, level 5: Very sleepy) on the sleepiness scale when the system was enabled increased by 34 percent compared with the system-disabled condition. The reaction time to visual stimuli was noticeably delayed and significant differences are acknowledged for a level 4 or above on the sleepiness rating scale. We believe that continuous long term investigation on actual driving (FOT; field operation test) should be carried out to validate the results in this study. We also analysed the relationship between eye closure ratio and the sleepiness rating scale and confirmed that eye closure ratio value of 0.26 corresponded to level 4 on the sleepiness scale where the reaction time delayed remarkably. Drawing on these findings, it is believed that a device can be designed to detect arousal level based on eye closure rate.
