在有条件的自动驾驶中,司机在沉浸在非驾驶相关任务(NDRT)中时与驾驶脱钩,可能会错过系统发起的接管请求(TOR),或者突然出现TOR可能会吓到他们。为了更好地为司机在紧急情况下更安全地接管做好准备,我们为自动驾驶提出了新颖的上下文感知建议警告(CAWA),以温和地通知司机。这将帮助他们在参与NDRT时保持警惕。关键的创新是,CAWA根据NDRT的背景调整预警模式。我们进行了一项用户研究,以调查CAWA的有效性。研究结果表明,与均匀分布在所有NDRT上的基于语音的警告相比,CAWA在更安全的接管行为、提高驾驶员的情景意识、更少的注意需求和更积极的用户反馈方面具有统计上的显著效果。
In conditionally automated driving, drivers decoupled from driving while immersed in non-driving-related tasks (NDRTs) could potentially either miss the system-initiated takeover request (TOR) or a sudden TOR may startle them. To better prepare drivers for a safer takeover in an emergency, we propose novel context-aware advisory warnings (CAWA) for automated driving to gently inform drivers. This will help them stay vigilant while engaging in NDRTs. The key innovation is that CAWA adapts warning modalities according to the context of NDRTs. We conducted a user study to investigate the effectiveness of CAWA. The study results show that CAWA has statistically significant effects on safer takeover behavior, improved driver situational awareness, less attention demand, and more positive user feedback, compared with uniformly distributed speech-based warnings across all NDRTs.
