Abstract
The debate over sustainable, eco-friendlier solutions gathers the industry attention all over the world at present. In this framework, the emission of pollutants constitutes one of the main ecological concerns for the present society, especially when it comes to Global warming. Particularly, vehicles powered by fossil fuels play a large role in that matter, representing one of the main sources of carbon dioxide Emissions. Therefore, it is expected that the automotive industry looks for more sustainable, less environmentally harmful solutions. Indeed, many countries have already set deadlines for the end of sales for such vehicles. With that being said, pure electric vehicles comprise one sustainable alternative for modern mobility, not only embodying zero-emission vehicles (ZEV) but being also greatly more efficient when compared to fuel-powered vehicles. This paper aims to testify such an advantage over a standard urban driving cycle, comparing a single-gear electric vehicle to a conventional 5-speed gearbox vehicle through computational models based on, the MATLAB/Simulink environment. The control strategies (gear shifting for the ICE car and electronic control for the EV) shall be the best ones for each model so that the highest possible efficiency is achieved in each situation.
