Abstract

The design of autonomous business vehicles must accommodate diverse usage scenarios such as reception, meetings, and rest within a limited cabin space, necessitating a systematic reconfiguration of internal functions and spatial layouts. Focusing on functional selection and spatial arrangement strategies, the work aims to study the design of autonomous business vehicle cabins. Based on an affinity diagram, the business activity requirements were analyzed, the Analytic Hierarchy Process (AHP) was employed to construct a functional hierarchy, an intelligent evaluation method was proposed by integrating expert scoring with large language model (LLM)-assisted judgment, thus summarizing the functional design strategies. Considering spatial constraints and functional interdependencies within the vehicle, a heuristic-rule-driven Genetic Algorithm (GA) was developed to efficiently generate and optimize spatial layout schemes. A user satisfaction index was introduced to evaluate the generated layouts and verify the effectiveness of the design solutions. The proposed "LLM-AHP-enhanced heuristic-rule-driven GA method" significantly improved the design logic and layout efficiency of designers in optimizing autonomous cabin configuration. User feedback indicates high satisfaction with the optimized outcomes, validating the approach and offering theoretical insights for multifunctional cabin design in autonomous vehicles.
