人类司机分心行为对无人车纵向速度控制的影响

Influence of Human Driver’s Distraction Behavior on Longitudinal Velocity Control of Autonomous Vehicle

  • 摘要: 无人车通常无法探测到人类司机的分心行为,这将导致无人车延迟地采取紧急制动来避免追尾。因此,本文致力于构建无人车控制与人类司机分心监测之间的桥梁,来辅助无人车预测潜在风险并像有经验的人类司机一样避让处于分心的司机,提高无人车的智能化水平和交通系统的安全性。首先,本文提出了一种整合了司机分心监测、车对车信息交换、无人车速度控制的可行系统框架。然后,基于卷积神经网络,本文提供了一种司机分心监测实现。最后,基于模型预测控制策略,本文提出了一种考虑了司机分心行为的无人车纵向速度控制方法,并给出持续可行性分析。仿真结果验证了本文工作的有效性。

     

    Abstract: It’s commonly difficult for autonomous vehicles (AVs) to detect human driver distraction behaviors, which would lead to probable late preparation for AVs to take brakes in time to avoid rear-end collisions. Hence, in this paper, we aimed to build a connection between AV control and human driver distraction detection, to aid AVs to predict potential risk and avoid distracted drivers like experienced human drivers. First, a practical system framework integrating driver distraction detection, vehicle-to-vehicle communication, and AV velocity control was proposed. Then, an implementation of driver distraction detection based on convolutional neural networks was put forward. Finally, a longitudinal velocity control method considering driver distraction behavior based on model predictive control was posed with persistent feasibility analysis. Simulation results validated the effectiveness of the work in this paper.
