驾驶经验对L3级自动驾驶接管绩效的影响

Effect of Driving Experience on Take-Over Performance of L3 Automatic Driving

L3级自动驾驶允许驾驶员在其操作设计域(ODD)内暂时脱离驾驶任务。当自动驾驶系统超出其限定的范围时,系统会发出接管请求(TOR)来提醒驾驶员及时接管车辆。为了探究具有不同驾驶经验的驾驶员在L3级自动驾驶过程中的接管绩效,针对24名不同年龄段、驾驶经验具有显著差异的参与者,设计了包含非驾驶任务和视觉辅助的紧急避障驾驶场景,在驾驶模拟器平台进行接管实验。结果表明,不同驾驶经验对反应时间没有明显影响,但是在驾驶绩效方面有着显著性差异。驾驶经验丰富的驾驶员在最大转向盘转角、转向盘转角标准差等指标上有着显著的提升,即经验丰富的驾驶员能够更平稳、安全地恢复对车辆的控制。此外,驾驶经验丰富与否在无视觉辅助的情况下差异更加明显。

L3 level automatic driving system allows the driver to leave from driving tasks temporarily within its Operational Design Domain(ODD).When the system reaches its boundary,it issues a Take-over Request(TOR),alerting the driver to take over the vehicle in time.In order to explore the take-over performance of drivers with different driving experience in L3 automatic driving,emergency obstacle avoidance driving scenarios with nondriving tasks and visual assistance are designed for 24 participants of different ages with significantly different driving experience to carry out the take-over experiment on the driving simulator platform.The results show that different driving experience has no significant effect on reaction time,but there is significant difference in take-over performance.Experienced drivers have a significant improvement in the metrics like maximum steering wheel Angle and standard deviation of steering wheel Angle;i.e.,experienced drivers can resume the control of the vehicle more steadily and safely.In addition,the difference between experienced and inexperienced is more significant without visual assistance.
