NDRT (non-driving related task)

非驾驶相关任务，指驾驶者或乘客在车内从事的与车辆操控无关的活动（如阅读、看视频、办公、游戏等）。在自动驾驶与汽车 HCI 研究中，NDRT 是评估乘客体验和晕车风险的核心自变量。

English Definition

"Any activity performed by a driver or passenger in a vehicle that is unrelated to operating the vehicle; in automated driving research, NDRTs are used to model the secondary activities drivers can engage in once control is delegated to the system."

用法说明 · 针对中文母语者

复数通常写作 NDRTs。与 secondary task（次要任务）含义有重叠但更聚焦于车内场景；可分为 visual NDRT（视觉型，如阅读）和 auditory NDRT（听觉型，如 podcast）。在 SAE 不同等级下允许的 NDRT 时长不同：L3 仅临时、L4 可长时间。

常见错误

·不要把 NDRT 默认等同于看屏幕，听觉型 NDRT 同样属于该范畴；也不要把 NDRT 与 distraction（分心）画等号，NDRT 是中性描述，分心是其可能后果之一。

"With the development of highly automated driving functions, drivers will no longer be in full charge of the driving task and can instead engage in a variety of non-driving related tasks (NDRTs), such as reading or watching a movie."

"In line with the theory of sensory conflict (Reason & Brand, 1975) and of sensory arrangement (Reason, 1978), NDRTs play a crucial role in the development of motion sickness symptoms."

"Reading (e.g., Karjanto et al., 2021; Kremer et al., 2022; Tomzig et al., 2023) and video watching (e.g., Brietzke et al., 2021; Mühlbacher et al., 2020; Schmidt et al., 2019) as naturalistic tasks represent the most common ones."
