User-Driven Strategies to Enhance Cockpit Comfort in New Energy Vehicles

As new energy vehicles become increasingly prevalent, cockpit comfort has emerged as a key factor in user experience. This study identifies and categorizes comfort-related factors into four main domains—acoustic, lighting, thermal, and human-computer interaction—based on literature review and user interviews, with 16 specific sub-factors. By applying subjective evaluation and entropy weighting methods, the relative importance of each factor is quantified. Results highlight the human-computer interaction environment, particularly voice interaction, as the most influential factor. Accordingly, this paper proposes a three-layered enhancement strategy: user-cognizant interface design for voice interaction, dynamically adjusting interaction and feedback models based on different scenarios, anthropomorphic voice interaction metaphors, which provide innovative ideas for the design of new energy vehicle cockpit comfort.
