This study proposes an AHP-SD-TOPSIS-AIGC integrated morphological design method to address multi-factorial design complexities in new energy commercial vehicle body styling under emotion-driven frameworks. Through literature retrieval and survey analysis, a Kansei evaluation system was constructed, with hierarchical design indicators established via Analytic Hierarchy Process (AHP) and weights determined through consistency matrices. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) identified optimal style forms exhibiting high emotional intention coupling, while edge detection algorithms extracted symmetrical spline features for body contour modeling. Artificial Intelligence Generated Content (AIGC) tools subsequently generated innovative solutions, validated through truck design applications to confirm method rationality and effectiveness. The results of the study show that the styling elements are accurately matched to user preferences and can identify target improvement points, and that the method can effectively achieve the output of the proposal for the design of commercial vehicle body morphology and is also applicable to passenger car-type vehicles to achieve the adaptation of multi-intentional emotional design.<\/jats:p>","DOI":"10.3390\/sym17111971","type":"journal-article","created":{"date-parts":[[2025,11,17]],"date-time":"2025-11-17T14:04:07Z","timestamp":1763388247000},"page":"1971","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Integrating Kansei Engineering and AI-Generated Image for Commercial Vehicle Body Morphology Design"],"prefix":"10.3390","volume":"17","author":[{"given":"Bo","family":"Li","sequence":"first","affiliation":[{"name":"Complex Mechanical Equipment Industrial Design Center, Xi\u2019an University of Technology, Xi\u2019an 710054, China"},{"name":"Faulty of Industrial Design, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhen","family":"Hu","sequence":"additional","affiliation":[{"name":"Complex Mechanical Equipment Industrial Design Center, Xi\u2019an University of Technology, Xi\u2019an 710054, China"},{"name":"Faulty of Industrial Design, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhang","family":"Liu","sequence":"additional","affiliation":[{"name":"Dectron Future Automobile Technology Co., Ltd., Xi\u2019an 713700, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zewei","family":"Wang","sequence":"additional","affiliation":[{"name":"Complex Mechanical Equipment Industrial Design Center, Xi\u2019an University of Technology, Xi\u2019an 710054, China"},{"name":"Faulty of Industrial Design, Xi\u2019an University of Technology, Xi\u2019an 710054, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,15]]},"reference":[{"key":"ref_1","first-page":"22","article-title":"The Development Trend of Commercial Vehicles under Carbon Neutrality","volume":"1","author":"Liu","year":"2024","journal-title":"Auto Time"},{"key":"ref_2","first-page":"2143","article-title":"Integrated optimization design of lightweight and fatigue life for the integrated structure of cell-to-frame","volume":"46","author":"Meng","year":"2024","journal-title":"Automot.
