Perception of vehicle speed by pedestrian
Rak, Martin ; Semela, Marek (referee) ; Bilík, Martin (advisor)
This master’s thesis deals with the issue of the perception of speed of a vehicle from pedestrian’s point of view. The theoretical part consists of a research into sense perception of humans and construction of motor vehicles. The practical part designs and describes the experiment which was performed in order to provide data used for analyzing different factors and their effect on the accuracy of vehicle speed estimations.

Design of autonomous family car interior
Šimala, Lukáš ; John, David (referee) ; Haltof, Vladimír (advisor)
The subject of this is the design of a family autonomous vehicle, which is designed to transport four to five people. The work contains an analysis of current vehicles as well as concepts on the basis of which the direction in the field of mobility can be deduced. The aim of this thesis is to create an interior design that takes into account the expected social, technological and economic development.

Mechanical-hydraulic model of vehical energy regeneration
Pisklák, Jan ; Vrbka, Martin (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis is a research about mathematic-physical model of vehicle’s kinetic energy regeneration. Mr. Pourmovahed A. et al. were dealing with this problem. He used the method of the determinated thermal time constants. Pourmovahed continued in study reports written by Green W. L. and Otis D.. His scientific work covers the analytical treatment which is compared with an experimental tests.

Options for the Determination of the Influence of Electronic Stabilization Systems of the Chassis on the Driving Dynamics of a Vehicle
Bilík, Martin ; Vémola, Aleš (referee) ; Panáček, Vladimír (advisor)
This diploma thesis deals with the possibilities of determining the influence of electronic stability systems on the chassis of the vehicle driving dynamics. In the introductory section is made theoretical analysis of road vehicle dynamics. Further description is made of some stabilization systems and situations and how to solve them by using these systems. Chapter 6.2.1 describes the methodology of practical experiment, which can determine influence of the stability system of the vehicle chassis on driving dynamics. The next chapter describes an experiment conducted and interpreted the measured values. The penultimate chapter is a simulation of this experiment using simulation software Virtual Crash. The last chapter is an evaluation of the experiment and compares the results with simulation programs using the same input conditions. The conclusion summarizes the results of this work.

Crash-Test Data Analysis - Side Impacts
Tillhonová, Veronika ; Ptáček, Petr (referee) ; Bradáč, Albert (advisor)
The diploma thesis deals with crash tests. Many international organizations specialize directly in conducting crash tests. Impact test simulates vehicle collision. The three most common test are front, side, and backstreets. The diploma thesis focuses on side conflicts. Side clashes are characterized by the fact that the first vehicle is damaged at the front and the second in the side. The measured data from these tests was evaluated to obtain the deformation energy consumed for permanent damage to vehicles. Deformation energy was calculated as equivalent to the individual speed of individual vehicles. EES values have been evaluated by various methods used in expert practice and compared. The impact tests were simulated to clarify assistance to experts in the analysis of traffic accidents.

The Influence of Modern Passive Safety Features in the Protection of a Vehicle's Occupants
Vostrejž, Jan ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
Thesis in the field of passive safety problems, traffic accidents and health outcomes of participants in road traffic accidents is aimed, inter alia, to create an overview of modern passive safety elements especially cars. The work deals with elements of the passive safety system and the impact on the crew vehicle. It describes the principle of operation, especially airbags, safety belts, belt pretensioner and it includes solution of limiters tensioning force in the safety belt and other elements that have the task of reducing the consequences of a traffic accident. The use of modern elements of passive safety provides increased protection for the crew and eliminates the formation injuries crew. The technical issue is therefore closely related to the healthcare industry and in particular the Court of medicine in the field of personal injury in relation to the types and characters of incidents, or by applying of the safety elements. There are also shown the actual road accidents in which were killed or injured members of crew with an analysis of the mechanism of injury with the use or non-use of safety elements.

Checking of Vehicle Identifiers
Motúz, Ondřej ; Panáček, Vladimír (referee) ; Motl, Jakub (advisor)
Diploma thesis is focused on identifiers of vehicles and their parts. The thesis gives an overview about available identifiers situated on the vecihles. Further more the thesis deal with potentional forgery and altering of identifiers and as a next shows potentional ways how to detect a manipulation with them. Practipal part of thesis includes a proposal of methodology for checking vehicles based on identifiers. There was also created a cathalogue of the Skoda vehicles. It gives an overview of identifiers for selected vehicles of the brand Skoda.

BMW Twelve-cylinder Engines
Macek, Libor ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
Bachelor’s thesis deals with mapping manufacture of BMW twelve-cylinder engines in accordance with current legislation. Thesis described the issue of engine construction and materials with respect to current requirements. Beginning of bachelor’s thesis is dedicated to the history od the BMW brand, especially to founders, first made vehicles and iconic vehicles. Carmaker has celebrated 25 years anniversary of V12 engines in 2012. Third chapter is dedicated to engine marking, because engine marking is difficult to understand. The next chapter is the most comprehensive because it contains a list of engines, including their description and comparison with the competition. In addition to passenger vehicles is thesis briefly focused on sport cars engines and prototypes that were never been mass-produced. The last chapter is devoted to the used technique, primarily to variable valve timing and variable valve lift . Furthermore, it aims to High Precison Injection, Electronic throttle control valves , CAN-Bus and marginally also TwinPower Turbo. In conclusion of the thesis is list of sources, tables and pictures of all engines and pictures explaining used techniques.
