Research on Fuzzy Grey Evaluation of Vehicle Experience Based on Scene Theory Model

This paper interprets and analyzes the scene theory in the field of automobile design, and summarizes the basic characteristics of the scene theory in the field of automobile design. The SBP (Scene Behavior Plan) car scene decomposition model based on the scene theory is proposed, which decomposes the user story into a combination of several scene modules, and converts it into quantifiable parameters or parameters that can be subjectively evaluated and assigned, finally forming an empirical evaluation scheme for the user story. At the same time, combined with the gray relational evaluation model, the evaluation method based on the user’s vehicle scenario is given. Finally, a case is used to illustrate the decomposition and evaluation process of vehicle use scenarios.
