Based on the analysis of aerodynamic characteristics of passenger cars and the research results of optimization, this paper solves the installation position, size, edge contour and surface shape based on the methods of space geometry model, physical differential equation and finite element analysis. To achieve the purpose of optimizing the mirror. Considering the actual demand of passenger cars and combining with the dimensions, frequent lines and spatial distribution of buses, the physical optical equations are established and the aerodynamic characteristics model of the vehicle is designed. The design criteria of the rearview mirrors of vehicles are proposed.
