Abstract

This study explores the effects of minor changes in automation level on drivers' engagement in secondary activities. Three levels of automation were tested: manual, semi-autonomous, and fully-autonomous. Potential distractor items were present and participants were instructed they could use them if they felt it was safe. Hand positions and engagement in secondary activities were manually coded. Participants were significantly less likely to engage in a secondary activity in semi-autonomous than fully-autonomous mode. Likewise, they were significantly less likely to use two hands to interact with a secondary activity in semi-autonomous mode than fully-autonomous mode. Gaze classification for each of the driver roles revealed that increasing levels of automation resulted in an increasing percentage of off-road glance durations. These observations suggest that in the event of automation failures, a driver in semi-autonomous driving may be in a somewhat better position to retake control and avoid collisions than during fully autonomous driving.

自动驾驶中驾驶员角色的行为影响

本研究探讨自动化程度的微小变化对驾驶员参与次要活动的影响。测试了三个级别的自动化:手动、半自动和全自动。潜在的干扰物存在，参与者被告知如果他们觉得安全就可以使用它们。手的位置和参与次要活动是手工编码的。在半自主模式下，参与者参与次要活动的可能性明显低于完全自主模式。同样，与完全自主模式相比，他们在半自主模式下使用双手进行辅助活动的可能性要小得多。每个驾驶员角色的凝视分类显示，自动化水平的提高导致越野凝视持续时间的百分比增加。这些观察结果表明，在自动驾驶发生故障的情况下，半自动驾驶的驾驶员可能比完全自动驾驶的驾驶员更能重新夺回控制权，避免碰撞。
