The main trend in the development of intelligent vehicles has been on ensuring comfort, safety, efficiency, and environmental sustainability. However, current research focuses primarily on the safety and energy saving of intelligent vehicles, and a comfortable driving experience through a human–machine interaction system has not been sufficiently investigated. This study used a high-fidelity 6-degree-of-freedom driving simulator to evaluate the impact of an independently-designed vehicle driving condition prompt (DCP) systems on subjective passenger comfort and motion sickness. The experiment showed that when future driving information is obtained through the vehicle DCP systems, the passengers' subjective comfort is improved, motion sickness is alleviated, and the degree of passenger posture instability is reduced. These conclusions contribute toward improving the comfort of autonomous vehicles and providing a reference for the future design of human–machine interaction systems for intelligent vehicles.

智能汽车发展的主要趋势是确保舒适性、安全性、效率和环境可持续性。然而，目前的研究主要集中在智能汽车的安全和节能方面，通过人机交互系统获得舒适的驾驶体验还没有得到充分的研究。本研究使用高保真 6 自由度驾驶模拟器来评估独立设计的车辆驾驶条件提示 (DCP) 系统对乘客主观舒适度和晕车的影响。实验表明，当通过车辆DCP系统获取未来的驾驶信息时，提高了乘客的主观舒适度，减轻了晕车，降低了乘客姿势不稳定的程度。
