Analysis of the electronic driving assistants
Vinecký, Radek ; Pexa, Martin (advisor) ; Pavlů, Jindřich (referee)
This bachelor thesis deals with active and passive safety systems in the automotive industry. The thesis describes the individual components of active and passive vehicle safety. The individual chapter deeply analyzes the most commonly used electronic driving assistants with a description of the individual parts and principles of the operation systems and their influence on the behavior and performance of vehicle. It also describes some sensors cooperating with the driving safety assistants. At the end of this chapter is described a future electronic driving assistant.
Within the statistic of the road safety was executed an analysis of the accidents in the years from 2000 to 2015 and evaluated a current trend of the accidents in relation with constantly increasing number of the registered vehicles.
The conclusion evaluates the general view of road traffic safety.

Performance measurement of petrol engines
Mader, Daniel ; Pexa, Martin (advisor) ; Pavlů, Jindřich (referee)
This thesis describes the various methods for measuring the performance parameters of petrol engines and on the selected engine (car) evaluate their accuracy with regard to the economic complexity of the methods.
In the first part of this thesis is described construction of combustion engines, explained the importance of individual performance parameters (power, torque, specific fuel consumpti-on) and characteristics combustion engines. This section, however, is focused on the issue of performance measurement, using both static and dynamic methods of measurement. The second part examined the various methods of measurement in practice on selected engine (car) with an assessment of their advantages and disadvantages and the financial cost of the-ir implementation.

Motor oils in aviation
Veselý, Jan ; Pexa, Martin (advisor) ; Pavlů, Jindřich (referee)
The aim of this thesis was to handle the problems of the literary tribodiagnostic, aviation oils using in piston engines and to provide analysis from taking oil samples from monitoring engines during working, evaluate it and recommend corection in maintanence service of these engines on based results typify as graphs. In chapter Analysis of the present state, there is described principle of working oil system in aviation engines including attributes of motor oils and demand requirements. The last part in this chapter is devoted to tribodiagnistic. In chapter Objective and methodology of thesis, there are described the machine on which the measurement was carried out and the methodology of individual tribodiagnostic analysis and sampling. Chapter Results contains the graphs based on the measured values including partial conclusion of the measurement and discussion.

The selected properties mineral and synthetic oils
Vu Tân, Hien ; Pošta, Josef (advisor) ; Pavlů, Jindřich (referee)
The main goal of this thesis is focused on comparing the selected properties of mineral and synthetic oils. For this was used operating monitoring and laboratory experiment and with them was compared properties. At operation was observed oxidation, sulfation, nitration, TAN, TBN and the content of metal elements in the oil. In Laboratory was experimental investigated the effect of increased temperature and change of color , viscosity and lubricity. The theoretical part of the thesis describes the basic of tribology and lubrication engineering, types of lubricants and oil properties and their production and distribution.
