Comparison of vibration emissions in electric and conventional cars

Currently, great importance is attached to the issue of environmental protection, also in the context of the impact of transport on the environment. Limited fossil resources, climate change, and global warming are driving the automotive industry towards more efficient and sustainable solutions. These problems are driving car manufacturers to use new technologies and alternative drive systems. Examples of such vehicles are electric cars (EV) and hybrid cars (HEV or PHEV). The issue of the impact of using these means of transport on the emission of pollutants other than exhaust gases is important. An example of such emissions is vibrations. Cars with conventional drive generate vibrations from the operation of the combustion engine. All vehicles, both conventionally and alternatively driven, emit vibrations as a result of the operation of the drive system, suspension system, and interaction of tires with the road surface. Vibrations also arise from unevenness of the road surface. At first glance, it seems that vibrations are lower when driving an electric car. In this article, vibration measurements were performed inside an electric vehicle and a conventionally driven vehicle in urban and highway conditions.
