To improve the olfactory experience satisfaction of intelligent cockpit vehicle fragrance users, and to find out the preferred fragrance categories of target user groups, this paper proposes a method for assessing vehicle fragrance preferences based on users' physiological signals. An experimental setup was created to assess the olfactory preferences of vehicle fragrance users, utilizing a smell experience tester as the odorgenerating device. Three commonly used vehicle fragrances, i. e., mint, jasmine and orange, were selected as the test samples. Thirtytwo participants were recruited for the test, and the changes in skin conductivity, pulse and respiration were measured and recorded by using the ErgoLAB multichannel physiological monitoring system. After the initial data processing on the ErgoLAB humancomputer interaction platform, users' subjective preference data were collected by using a semantic difference scale. A comprehensive evaluation model based on the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) was then established to analyze the objective data, and correlation analysis was conducted using Spearman's correlation coefficient to validate the findings. The results show a significant positive correlation between the comprehensive scores of objective physiological data and users' subjective preference ratings, with mint fragrance being the most satisfying to users.
