Abstract

In several circumstances, a level-three automated vehicle cannot continue driving in an automated driving mode and requests a human driver to take over. In this study, a series of experiments to examine how to provide a TOR was conducted. First, for forty-one persons, a HUD icon, earcon, seat vibration, and combinations were compared. The results indicated that the HUD icon-earcon and HUD icon-seat vibration were the most effective. Second, the combinations of A-pillar LED light and cluster icon (visual), earcon and speech message (auditory), and presence/absence of seat vibration (haptic) were compared. Thirty-six volunteers participated in the ADS failure and forty in the highway exit experiment. In the ADS failure, the combination of A-pillar LED light and seat vibration (AH) reduced the RT but can induce stress. In the highway exit, a speech message is recommended due to control stability, and the AH is not recommended due to longitudinal instability.
模拟自动驾驶车辆计划和非计划接管请求预警方法的开发
在一些情况下,三级自动驾驶汽车无法继续在自动驾驶模式下行驶,并要求人类驾驶员接管。在本研究中,进行了一系列实验来研究如何提供TOR。首先,对41个人进行了HUD图标、耳塞、座椅振动和组合的比较。结果表明,HUD图标-座标振动和HUD图标-座椅振动最有效。其次,比较a柱LED灯与集群图标的组合(视觉)、耳塞与语音信息的组合(听觉)以及有无座椅振动的组合(触觉)。36名志愿者参加了ADS失败实验,40名志愿者参加了高速公路出口实验。在ADS故障中,a柱LED灯和座椅振动(AH)的组合降低了RT,但会引起应力。在高速公路出口,由于控制稳定,建议使用语音留言,由于纵向不稳定,不建议使用AH。
