摘要
随着自动驾驶技术研究的深入,乘员舒适性是除安全性外另一个关注重点。然而,现有研究多以传统汽车舒适性为对象,未充分考虑自动驾驶中驾驶员由于操纵权丧失而表现出的乘坐舒适性的新特征。除平顺性外,自动驾驶汽车的乘员舒适性还受平衡觉刺激和视觉刺激影响。前者由车辆行驶行为引发,后者由外部环境引发。本文设计换道工况下以平衡觉和视觉刺激强度为变量的3×3双因素混合试验,探究其对自动驾驶乘员舒适性的影响规律。通过问卷和访谈获得受试者的舒适性主观评价,利用皮肤电水平验证了主观评价结果的可靠性。结果表明:(1)乘员舒适性受平衡觉和视觉因素的共同影响;(2)随着环境视觉危险程度增大,乘员舒适性的主要影响因素从平衡觉刺激向视觉刺激转变,乘员倾向于牺牲一定程度的体感舒适性以换取视觉舒适性。
With the development of autonomous driving technology,passenger comfort is another focus in addition to safety.However,researches mostly focus on the comfort of traditional vehicles,failing to fully consider the new features of the passenger comfort due to the loss of control rights when autonomous driving.Besides riding comfort,passenger comfort is also affected by the balance stimuli and visual stimuli.The former is caused by the driving behavior of vehicles,while the latter is caused by the external environment.This paper employed a 3×3 mixed design(balance stimuli×visual stimulus)under lane change maneuvers to study the influence rule of the two factors on the passenger comfort of autonomous driving.The subjective evaluation of the passenger comfort was obtained through questionnaire survey and interview,and the reliability of the subjective evaluation results was verified with the skin conductance level.The results show that:(1)Passenger comfort is influenced by the factors of balance and vision.(2)With the visual risk of the scenarios improving,the main influencing factor of passenger comfort changes from the stimulus of balance sense to the stimulus of vision.Passengers tend to sacrifice a certain degree of physiological comfort in exchange for visual comfort.
