To address the issue of motion sickness among passengers in autonomous driving scenarios, which significantly compromises the travel experience, this study proposes an olfactory and auditory mitigation method based on EEG analysis. Using mint gas and alpha brainwave music as stimuli, an autonomous driving environment is constructed via a driving simulation platform. EEG signals are collected from 30 participants, and three motion sickness mitigation protocols (auditory, olfactory, and combined auditory-olfactory) are designed. Combining temporal and frequency domain features (mean, variance, skewness, kurtosis, power spectral density) from EEG signals with classification algorithms, an EEG-based motion sickness recognition model is developed. This model is then used to evaluate the efficacy of the three approaches in alleviating motion sickness. Results indicate: The auditory & olfactory protocol demonstrated the highest efficacy, reducing Relief Index (RI) by an average of 58%. The olfactory-only protocol showed moderate efficacy, reducing RI by an average of 35%. The auditory-only protocol exhibited the lowest efficacy, reducing RI by an average of 21%.
