摘要
为降低混合动力汽车(HEV)发动机频繁启停引起的噪声与振动,提高乘坐舒适性,文章介绍了HEV的结构、驱动模式的特点以及发动机启停过程的噪声振动特点,分析了HEV的发动机启停过程产生的噪声与振动的根本原因,并提出了在此过程中噪声和振动源的控制措施,使HEV的发动机启停过程的噪声与振动得到降低,总结了HEV发动机启停的噪声与振动特性研究的发展趋势。
In order to reduce noise and vibration created by frequent start-stop of engine and improve the ride comfort of hybrid electric vehicle （HEV）, this paper introduces the characteristics of structure and drive mode, and the characteristics of noise and vibration in the process of engine start-stop of HEV. The root causes of noise and vibration generated are analyzed in the process of engine start-stop of HEV. The control methods of noise and vibration are proposed in the process so that the noise and vibration can be decreased. The developing trend of noise and vibration characteristics of engine start-stop is concluded.
