摘要：

In this paper, the tuning method and process of acoustic vehicle alerting system (AVAS) specified in national standard for electric vehicle running at low speed are expounded with the effects of the frequency spectrum energy distribution in AVAS on the lowest limit of exterior noise and interior sound quality emphatically discussed, and a sound quality evaluation method for AVAS is proposed. The results of test and evaluation show that by improving the frequency spectrum distribution of AVAS in the process of speed variation, the balance between the lowest noise limit specified in regulation and internal sound quality is achieved, enabling more all-roundly investigation into the effects of AVAS on the NVH performance of vehicle. © 2020, Society of Automotive Engineers of China.
