Abstract:

The structural characteristics of hybrid electric vehicle (HEV) are analyzed in this paper. The changes of the noise and vibration sources and their characteristics due to the structural change are studied. The methods for controlling the noise and vibration of the HEV are put forward. Finally, the difficulty and the development trend of the noise and vibration control of the HEV are summarized.

Key words: vibration and wave, noise and vibration, hybrid electric vehicle (HEV), electric motor, engine
