Analysis of Documentation of Real Damage to Vehicles in Road Accidents
Novotný, Václav ; Kovanda,, Jan (referee) ; Vémola, Aleš (advisor)
This diploma thesis deals with a comprehensive analysis of the photographic documentation of vehicle damage in traffic accidents. A systematic overview of the current documentation and included inspection is carried out in the analysis. Police records are compared with records made during the crash tests. Further, the documentation in this thesis is divided into two groups of conflicts. The representative of the accidents are described in detail and then evaluated. Similarly, this procedure is practiced on other car accident that reflect the mutual deformation. The result of this thesis is to determine the optimal location of the lens for the acquisition of documentation and establishing a baseline number of photos to document damage to the vehicle after the traffic accident.

Analysis and Evaluation of Documentation on Real Vehicle Damage after Minor Traffic Accidents
Kuncová, Andrea ; Tylšar, Vladimír (referee) ; Vémola, Aleš (advisor)
Diploma thesis analyzes documentation recieved from city magistrates,insurance companies or directly from police,concerning minor accidents. Documentation consists of a road accident reports,photodocumentation and plans of a real life collision sites,filed by the police and its experts. Analysis of this documentation and its consequent evaluation shows the extend of the damage occuring to an actual vehicles involved in a minor road accidents and what evidence left on site by these collisions. Informations gained from the analysis could be used as a guide when processing an insurance claim.

Extrication of Persons Trapped in Crashed Vehicles with Respect to their Construction
Pirner, Adam ; Kupka, Petr (referee) ; Vémola, Aleš (advisor)
This thesis deals with the topic of extrication of people trapped incrashed vehicles regarding the construction of the vehicle. Part of the resources needed for this theses was taken from a literary survey drawn up with the help of the Research and scientific library in Hradec Králové according to the given topic and key phrases. The first part of the thesis deals with specific parts of the constructions of cars. This part is followed by description of road accidents, various kinds of accidents and possible deformations of cars after accidents. The thesis deals with extrication itself made by fire brigades, suitable procedures, kinds of interventions and means of used technical equipment. Another part suggests ways of saving trails and evidence during road accident interventions. Final part of the thesis is focused on overall analysis of the given problem based on personal experience, suggestions, negative aspects of the current situation and differences in training of possible situations with reality at the site of the accident.

Analysis of impact of active safety elements in vehicles on pedestrian protection for traffic accident investigation
Vertaľ, Peter ; Kovanda, Jan (referee) ; Kropáč, František (referee) ; Vémola, Aleš (advisor)
Increase the probability of prevent road accidents by installing autonomous systems in a vehicles is the current trend in the field of active safety with a focus on pedestrian safety. The work deals with the evaluation of intervention of active safety systém for pedestrian detection assembled in series production. Benefit of active safety systems to prevent road accidents can be achieved, for example, early warning driver of a potential collision situation sufficiently in advance to reaction and post-maneuver (braking, yaw, ..). The evaluation of the intervention of active safety systems, which aim to prevent an accident with a pedestrian is necessary to experimentally evaluate the behavior of these systems. The main objective of this work is to test the selected systém based on different types of reál accidents. Atthe time of the measurements and present, are not for experts and specialists in the field of road traffic accidents publicly accessible data about the behavior of such a systém. The work aims to evaluate the behavior of the Volvo systém in inducing reál traffic situations. For the evaluation of this systém are precisely analyzed fatal traffic accidents with pedestrians in the urban area (speed of vehicles up to 60 km/h). Simulated traffic situations by their nature cover the most common critical situations in urban traffic. Expert community and the professionals who deal with the solution of traffic accidents receive this work valuable data to deal with such accidents. Based on these measurements give more expert input data to solve a collision with a pedestrian. The basis for understanding the behavior are created graphs of distance, speed and time at a key moment of the collision. These key moments include entry a pedestrians to driving corridor of the vehicle, system's response to conflict situations, warn the driver and then autonomously brake active safety systém

Impact of Chosen Chassis Electronic Systems on Driving Dynamics of a Vehicle
Schejbal, Jan ; Hlávka, Stanislav (referee) ; Vémola, Aleš (advisor)
This work deals with the impact of selected electronic chassis systems of modern vehicles, their driving dynamics. The general aim of this work is to create the basic methodology for assessing casualties of the influence of these systems. The thesis is describing functions and effects antilock and stability systems on vehicle dynamics. Below are possible methods and systems for determining the influence on accident plot. As part of the study was performed measuring the impact of anti-lock system on the vehicle. The result of this work is the basic methodology to the analysis of road accidents involving vehicles with electronic chassis systems.

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.
