Experimental methodology of measuring
Lojková, Lea ; Hejtmánek, Petr (referee) ; Havlíková, Marie (advisor)
This work is focused on the development of a thorough study about ISO standards focused on the vehicle dynamics, standardized tests of vehicle dynamics and measured variables that allow us to describe and model the behaviour of riding vehicles properly. In the Appendix A of the thesis, there is a list of all known ISO standards dealing with given topic. The standard ISO 15037-1 Road vehicles – Vehicle dynamics test methods, Part 1: General conditions for passenger cars is described in detail, including the forms for test reports and the Appendix C and D. In the thesis, there is also described a model of minimal needed measuring system that is still in good accordance with the standard ISO 15037-1 and fulfills all its requirements. Detailed description of all used sensors that are used to measure required variables is given, as well as a short description of all sensors that are used for measurement of other variables. After that, measurement abilities of the instrumentation of measuring system RIO used in ÚADI FSI Brno is compared and confronted with requirements given by the standard, to see, if all given criteria are properly fulfilled. Because of the fact that standard-given criteria are quite mild, while the equipment of the faculty is high-level technology, mostly made directly for measuring of dynamic parameters of the vehicles, including racing vehicles, the system is in full accordance with the standard ISO 15037-1.

Effect of Active Vehicle Safety in the Prevention of Road Accidents
Franc, Šimon ; Frič, Jindřich (referee) ; Panáček, Vladimír (advisor)
This diploma thesis focuses on effects of active vehicle safety on the prevention of traffic accidents. In the introductory section, the term of active safety is defined and divided into four categories. In next four chapters, the particular elements of active safety are described in more detail and some selected elements are described in depth. Chapter seven includes a questionnaire; it enquires opinions of people about some of the elements of active safety. Practical road tests were conducted as part of this work. Theirs description and evaluation are in the last chapters.

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.

Dynamic parameters of sports and conventional vehicles
Tesař, Michal ; Janoušek, Michal (referee) ; Vémola, Aleš (advisor)
This master´s thesis is focused on chosen dynamic parameters of a sport vehicle represented by student formula Dragon 7 and comparison of these parameters with conventional vehicles represented by two exemplars of ŠKODA Superb III. Driving tests used for the comparison are simulating the real driving situations from the roads in order to possibly use those for the road accident analysis in the future. All the measurements were taken under lower adhesion conditions which might help solving of the road accidents under such conditions in the future. There is also a description of vehicle driving systems and components which have an influence on the vehicle´s driving dynamics incorporated in the thesis.
