Introduction to NVH Aspects of Hybrid and Electric Vehicles
The influx of different hybrid and electric vehicle configurations has brought about unique NVH challenges from a variety of sources. NVH refinement is an important aspect of powertrain development and the vehicle integration process. While developing the NVH behavior of the vehicle is critical to satisfy customer expectations, it is also important to consider the influence of reduced exterior noise levels on pedestrian safety. This course introduces participants to basic NVH principles and unique NVH challenges encountered in the development of HEV, ReEV, and EV including engine start/stop behavior, electric motor whine, driveline NVH, body structure, influence of noise from accessories, and sound quality development, as well as potential countermeasures.
What Will You Learn
Upon completion of this course, you will be able to:
- Articulate the basic principles of NVH
- Describe the relative importance of powertrain noise, wind noise, and road noise in the vehicle's interior
- Identify the key sub-components of powertrain noise and means to control them
- Explain the key NVH issues specific to electrified vehicles and means to develop appropriate countermeasures
- Identify key metrics available to assess the NVH performance of electrified vehicles
- Develop an awareness of advanced NVH methodologies available to design the sound character of electrified vehicle
