A Multisensory Neural Evaluation Method for High-End Perception of Automotive Cockpits Based on Real-Vehicle Human Factors Experiments

Abstract

Against the backdrop of accelerating premiumization among Chinese new energy vehicle brands, an objective measurement method for perceived luxury has become a critical methodological challenge for the industry. This study conducts in-vehicle human factors experiments using Rolls-Royce, Voyah Dreamer, and Zunjie as test vehicles, investigating the neural cognitive mechanisms and quantitative evaluation methods of cabin luxury perception across five sensory dimensions: somatosensory, tactile, olfactory, auditory, and visual. The experiment collects electroencephalogram (EEG), electrocardiogram (ECG), electrodermal activity (EDA), skin temperature (SKT), and eye-tracking data, which are integrated with subjective evaluations for comprehensive analysis. Based on these findings, this paper establishes a four-dimensional quantitative evaluation framework encompassing physiological arousal, EEG processing, behavioral responses, and subjective ratings, and proposes a sensory consistency threshold model to explain the nonlinear integration mechanism underlying overall perceptions of luxury.
