Abstract: To address the problem that wind noise is more obvious in pure electric vehicles without the mask of engine noise, the main focus is to sort out the mechanism of wind noise generation and the development process of wind noise performance, and then to control the wind noise of pure electric vehicles from the early stage of design, analyse the typical problems in the development process, combine with actual cases to avoid the problems and avoid wind noise problems in real vehicles. The wind noise of the final production vehicle is subjectively evaluated as good, and the objective test meets the preliminary wind noise development target, which verifies the effectiveness of the design scheme.

Key words: Pure electric vehicle; Wind noise; Control method; Key points of design
