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.

Braking marks creation analysis in dependence of vehicle deceleration
Svoboda, Lukáš ; Panáček, Vladimír (referee) ; Vémola, Aleš (advisor)
The work is divided into two parts – theoretical and practical. The first, theoretical part is focused to introduce the problematics to the reader, describing the concept of translation motion and brake physics, defining terms adhesion and friction, skid, calculation formulas etc. After the mechanics chapter follows the chapter about tire and its composition and properties, and a brake system chapter, describing Anti-lock brake system (ABS) and some other important brake-support systems. Second part of this thesis is focused on practical side, which contains acceleration measuring and skid marks creation, followed by evaluation of measured data in form of calculations and graphs.

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.

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.

Use of Diagnostic Methods for Assessing the Technical State of Vehicles
Skoupý, Petr ; Krejčíř, Pavel (referee) ; Panáček, Vladimír (advisor)
The thesis has focused an influence of actual automotive diagnostic methods which can be used for the evaluation of vehicles´ technical conditions. I´ve sorted various automotive diagnostic methods included the different devices in the first part of thesis. Second part describes the vehicle valuation procedure according to methodology of Czech Experts´ Norm No. I/2005. Third part has introduced the valuation procedures carried by means of diagnostic devices included practical examples. Fourth part compares and evaluates results. Lastly the thesis presents capabilities of technical diagnosis during the vehicle valuation procedure and possible view of both methods.

Analysis of Internal Vehicle Noise and its Influence on Active Safety
Dolejský, Lukáš ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
Thesis is focused on the impact of the inside noise of the car on conditional driver safety, which is presented by reaction times on simulated stimulus. In introduction, there is a theoretical definition of the security of the vehicles, inside noise, and its methods of measurement. Practical part consists of description and realization of the measurements of the impact on the inside noise in the car on reaction time of drivers. Conclusion includes evaluations of the measurements and findings, which results from them.

Influence of Tyre Defect on the Driving Dynamics of a Vehicle
Kubík, Adam ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
In this thesis, an effect of a tyre defect on the driving dynamics of a vehicle is dealt with. The first part of the thesis is mainly concerned with the vehicle dynamics, road resistance, adhesion, orientation characteristics of the tyres and slowing down. This chapter is followed by an overview of the manufacturing process and construction of modern passenger car tyres. The practical part is focused on driving tests that are used to demonstrate the influence of tyre defects on handling characteristics of the vehicle. The main focus of this thesis is on directional variation, braking distance, deceleration and lateral acceleration. The very end of the thesis concentrates on tyre defect in higher speeds and its after-effects as well as precautions for mitigation of these after-effects.
