Design Method of Small Recreational Vehicle’s Interior Space Based on User Behavior Data Analysis

Aiming at the problem of interior space design of small recreational vehicle, this paper proposes a functional facility grouping method based on user’s behavior data analysis. Firstly, drawing on the properties of correlation coefficient in statistics, the correlation degree between different functional facilities is defined according to the usage time interval, to establish the correlation degree matrix; and then the correlation degree matrix is proved to be a real symmetric positive-definite matrix; finally, based on the correlation degree matrix, the factor analysis method is adopted for grouping all the functional facilities to maximize the correlation degrees between functional facilities in the same group, and minimize the ones between different groups, so as to better satisfy the users' needs for the convenience and improve the comfort of the drivers and passengers. Theoretical analysis and practice show that the method proposed in this paper is based on rigorous mathematical analysis which can be used as a general theoretical model for grouping functional facilities in small recreational vehicle.
