Winter, Josef ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis deals with problematics with noises and vibrations else known as Noise, Vibration and Harshness (NVH) at electric vehicles type Battery Electric Vehicle. The attention is drawn to the powertrain system because the powertrain system was electrified. The goal of this thesis is to present sources of noise and vibrations and to show examples of experiments that are done on the vehicles to improve driving comfort of driver and passangers. In the end the measurement and analysis of noises and vibrations were done at electric vehicle by Hyundai from Institute of Automotive Engineering.
