摘　　要：为保证智能网联汽车的乘坐舒适性与用户接受度,建立乘员晕车缓解认知过程模型,提出一种基于嗅觉刺激的乘员晕车缓解方法。首先充分考虑乘员满意度和晕车缓解功能性要求,设计开展晕车缓解嗅觉刺激材料筛选实验,选定嗅觉刺激材料的气味类型和浓度。接着为探究不同晕车程度与生理表征之间的映射关系,验证嗅觉缓解方案的有效性,设计开展乘员晕车缓解实车实验。结果表明:乘员主观晕车程度与皮电激活度指标呈正相关,与脑电不对称值呈负相关。同时,20%浓度的姜花气味经10 s释放能够有效缓解乘员晕车症状,平均缓解效果达到22.17%,在主客观维度上得到了一致性验证。In order to enhance the comfort and user acceptance of intelligent connected vehicles,a cogni⁃tive process model for passenger carsickness mitigation is established in this paper and an olfactory stimulationbased mitigation strategy is proposed.Firstly,a screening experiment of olfactory stimulation materials for carsick⁃ness relief is designed and carried out,fully considering occupant satisfaction as well as the functional requirements of carsickness relief,to select the odor type and concentration of olfactory stimulation materials.Then,a carsick⁃ness mitigation experiment based on a real car is carried out to investigate the mapping relationship between differ⁃ent degrees of carsickness and physiological representations and further validate the efficiency of the olfactory miti⁃gation method.The results show that the subjective carsickness degree is positively correlated with GSR activation and negatively correlated with EEG asymmetry.Moreover,releasing 20%ginger blossom odor for 10 seconds can ef⁃fectively relieve carsickness symptoms,with an average relief effect of 22.17%,which is verified in terms of subjec⁃tive and objective dimensions.
