Influence of heavy vehicle load to the vehicle deceleration
Jirásková, Iveta ; Tylšar, Vladimír (referee) ; Bradáč, Albert (advisor)
The diploma thesis deals with the issue of braking trucks at different loads. The theoretical part defines the basic construction of trucks, truck brakes, the braking process and the factors that affect braking, braking deceleration, and legislative requirements for truck brakes. The practical part describes the course of experimental measurements, the use of the technique, the place of measurement, atmospheric conditions and used trucks. At the end of the work, based on experimental measurements, the obtained values of braking deceleration of trucks are evaluated.

Analysis of the vehicle powertrain after leakage of service fluids
Paťha, Vladimír ; Tylšar, Vladimír (referee) ; Tokař, Stanislav (advisor)
This master’s thesis deals with the issue of damage of the vehicle’s drivetrain due to the operating fluid leakage. The aim of the thesis is to clarify the severity of this type of damage and, alternatively, the times during which these failures can occur. The theoretical part describes the issues of lubrication and cooling systems, including the consequences of sub-optimal operating conditions. The evaluation is based on conducted experiments and is compared with already published tests. The parts that are most often damaged are also described. Finally, the recommendations for lowering the extent of damage are formulated.

The Energy of a Flying Object Necessary for Damaging the Vehicle Windscreen
Havlík, Ondřej ; Tylšar, Vladimír (referee) ; Bradáč, Albert (advisor)
The theoretical part of the thesis entitled "The Required Energy of a Flying Object to Damage a Windscreen" covers the historical development of glass as a raw material and its further use as a key material for the automotive industry. In the following chapters, the thesis provides an analysis of a windscreen in general including the material composition of various windscreen manufacturers, the distribution according to the accessories used in the windscreens, and the various options of placing a windscreen in a car bodywork. The homologation of a windscreen and the procedure for replacing or repairing a windscreen after a damage is also covered. Lastly, the experimental part of the thesis describes the process of testing the required energy of a flying object to damage a windscreen.

Turning Radius Limits of Vehicles and Common Drivers and Their Application in Software for Traffic Accident Reconstruction
Jelínková, Eliška ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
The diploma thesis deals with the turning technique of cars and common drivers. The thesis examines the behavior of vehicles and drivers when cornering, forward and reverse driving. The aim of the thesis is to analyze the technique of turning vehicles and common drivers and apply the acquired data to simulation programs for road accident analysis. The individual aims of the thesis are theoretical description of the given problem and experimental verification of the parameters of radii, angles and time course of turning of different vehicles and common drivers in forward and reverse driving under comparable conditions and to describe mutual relations.

Time Analysis of Observation in Interaction Between Driver and Pedestrian
Michalčíková, Lucie ; Tylšar, Vladimír (referee) ; Belák, Michal (advisor)
The theoretical part of this thesis deals with the description of sensory processes, human eye and visual perception. The following are traffic participant and get data using the method of eye tracking. The practical part consisted in the evaluation of driving video recordings describing the driver's observation. The frequency and length of the pedestrian observation was evaluated, and the graphical processing was performed depending on whether the pedestrian actually crossed the road or simulated walking on the side of the roadway.

Driving Dynamics of Motorcycles
Šplíchal, David ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
This diploma thesis called Motorcycle Race Dynamics captures the development and development of motorcycles, a description of types, design elements and the techniques of riding a motorcycle. However, the aim of this work is to organize, perform and evaluate the measurement of braking deceleration and the crossing of motorcycles. Before separate data processing, a theoretical methodology for measuring transverse displacement and braking deceleration is proposed. This requires enough motorcycles, experienced riders, two cameras, a measuring instrument and precisely dimensioned lines. The lateral displacement and braking deceleration measurements are then performed and subsequently evaluated. Output of this work include, in addition to videos, an overview of transverse displacement times, or longitudinal deceleration output values gained from braking.

Circumstances and Legal Consequences of Daytime Road Accidents with Pedestrians
Rožková, Magdaléna ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
The diploma thesis „Circumstances and Legal Consequences of Daytime Road Accidents with Pedestrian“ deals with the interpretation of legal decisions on traffic accidents causes by the vehicle during the day and where the other participant was a pedestrian. The main aim of this work is to find the established limits for the assessment of fault in comparable accident situations. Basic concepts, as a traffic accident, participants of traffic accidents and the position of an expert in the criminal proceedings, are defined within the theoretical part of the thesis. It also deals with the biomechanical aspects of a pedestrian – vehicle collision and the violation of specific regulations. Approximately 1,530 judical decisions were studied and analyzed in the analytical part, of which 40 were selected, that correspond to the requirements of this thesis. In the analytical part there are also 4 expert opinions provided by the Institute of Forensic Engineering of Brno University of Technology, where the above – mentioned limits for the assessment of accidents were applied, as well as the decision according to the jurisdiction.

Defensive drive
Zapletalová, Kateřina ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
The diploma thesis deals with the issue of driver education and practice safe, dangerous and aggressive driving. The aim is to map the issue of safe and defensive driving and define the principles of defensive driving. The first part deals with the theory of defensive driving, which analyzes psychologically and legally sides of that problem. Another part deals with road safety, which is described in the context of direct and indirect indicators of road safety. The research then analyzes in detail the specific situation on the road that leads to accidents. This analysis is performed on based data of real accidents. Of particular situations accidents are then defined the principles of defensive driving.

Estimation of the technical level of FORD vehicles for valuation purposes
Valešová, Jaroslava ; Tylšar, Vladimír (referee) ; Kledus, Robert (advisor)
he paper analyzes the current production of Ford cars and analysis in terms of development of their technical level. It was created parametric comparison of currently produced vehicles on the market. For the most common models of the Fiesta, Focus and Mondeo is compared to change the technical level over the last 10 years. On the basis of these evaluations was created basis for determining the coefficient of technical level. A further assessed changes in exchange values for the most common models for 10 years, and their comparison with the corresponding amortization scales in accordance with the methodology Valuation standard number I / 2015 and so were consistently reflected changes in technical standards for older models.
