Electric racing truck concept design
Prchal, David ; Beran, Martin (referee) ; Svída, David (advisor)
This bachelor’s thesis is focused on projecting electric or hybrid conception of Rally Dakar racing truck. The researching part is focused on the Dakar Rally, analysis of parameters and construction of current racing trucks with internal combustion engines and current low emission concepts used in this competition. The practical part is firstly focused on analysis of energy requirements for one stage of competition and critical evaluation of possibilities of hybrid or electrical solutions. Subsequently, the EREV conception is chosen and the parameters for components are suggested. Emphasis is placed on ensuring that the concept has as few compromises as possible and is comparable in terms of theoretical driving performance to conventional racing trucks that use an internal combustion engine.

Vibration and noise of electric vehicles
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.

Cars as sources of polluting substances and greenhouse gases in the light of legislation
Vodička, Jiří ; Fiala, Zdeněk (referee)
Submitted thesis focuses on a topic which cannot be described as classical legal topic in the Czech Republic. Nevertheless, in times of climate change and general need of shift to zero emission transportation and sustainable development of our society, this topic is very much needed. The thesis provides a general framework of type approval legislation of new vehicles of the EU and national legal system with an emphasis on test cycles such as WLTP and RDE. The thesis analyses Euro emission norms which define thresholds for polluting substances from exhaust fumes and at the same time analyses union legal regulation of CO2 emissions from new vehicles. To fully develop zero emission transportation, it is necessary to have sufficient corresponding infrastructure (e.g. charging stations). Because of this dissertation focuses on legislation concerning alternative infrastructure and selected alternative fuels. The thesis also analyses specific legal instruments (direct and indirect) which could be used as tools for the development of zero emission transportation and for improvement of air quality, especially in urban areas. Within indirect legal instruments, state aid and other financial incentives which can promote the development of zero emission transport are analysed. Direct legal instruments such as...
