Abstract: Amid the accelerated transformation and upgrading of the new energy vehicle industry, the issue of mid-to-high-frequency whine noise inside battery electric passenger vehicles has become increasingly prominent due to the characteristics of their electric drive systems. This noise affects driving comfort and constrains product competitiveness. Therefore, conducting targeted noise control research holds significant industry value. This paper combines experimental analysis to identify the main noise sources as motor electromagnetic noise and gear meshing noise from the reducer. An active interior noise control approach is attempted. The results show that the system operates stably under constant-speed conditions of 40～80 km/h, achieving a noise reduction of up to 14 dB(A) at the target whine frequency and a maximum overall sound pressure level reduction of 2.86 dB(A), providing a practical reference for the performance optimization of battery electric vehicles.
