Effect of non-driving related task and seat back angle on preferred seat parameters in highly automated vehicles
研究在高度自动化车辆中，不同视觉需求的任务（如放松、看前方、用笔记本电脑、看平板视频）和座椅靠背角度（20°、40°、60°）如何影响用户偏好的座椅参数和坐姿不适感，发现靠背角度影响所有参数，而任务只影响头枕相关参数。
This study investigated the effects of non-driving related tasks (NDRTs) and seat back angles (SBAs) on preferred seat parameters and seating discomfort in highly automated vehicles. Using a static, reconfigurable experimental seat, 32 participants self-selected preferred seat parameters for four tasks with varying vision demands (relaxing, looking forward, working on a laptop, watching a tablet video) at three SBAs: 20°, 40° and 60°. Results show that SBA influenced all self-selected seat parameters, while task only affected those related to the headrest. Fore-aft headrest adjustability is necessary to support different NDRTs, particularly in reclined postures. Upright and moderately reclined positions were preferred for downward-looking tasks like laptop or tablet use, while more reclined positions were better suited for relaxing without visual demand. The findings also highlight the importance of suitable support for tablet use to reduce discomfort. They could be useful for seat and vehicle interior design in future automated vehicles.
