Abstract: The vibration and noise caused by vehicles make drivers and passengers uncomfortable and produce environmental pollution. Traffic safety and service life of electric vehicles are also affected. Noise, vibration and harshness (NVH) performance is the key index to evaluate the ability to controlling the vibration and noise of vehicles and ride comfort of drivers and passengers. The requirement and evaluation method for NVH performance of the vehicles are analyzed. Based on the origination and formation mechanism of vehicles vibration, combined with the research method of vibration characteristics and NVH performance design, the research status of vibration characteri- stics and NVH performance controlling are reviewed for electric vehicle powertrain and suspension system of electrical vehicles. Vibration absorption technologies are analyzed. The problems on vibration controlling are pointed out. Improving the accuracy and popularity of computer aided design (CAD) and computer aided engineering (CAE) modeling, optimizing the structure of the whole vehicle assembly, upgrading materials configuration and multi-unit synergy controlling are the development trend for improving NVH performance of electric vehicles, which can provide a reference direction to project design and realization of the vibration and noise controlling for electrical vehicles.
