Analýza brzdových systémů motorových vozidel
Janák, Josef
Bachelor thesis deals with problems of motor vehicle braking systems and systems associated to them. The introduction deals with the division of brake systems and sys-tems according to various criteria. It continues with the composition and main parts of hydraulic brakes up to the main content of this work, namely the design and function of drum and disc brake systems. Then it follows a with a little description of the electro-hydraulic braking system and the end part of the thesis is focused with the anti-lock and stabilization systems associated with the brake system of the car and the length of the braking distance.

Vývoj aktivních a pasivních bezpečnostních prvků osobních automobilů
Kubín, Tomáš
In my bachelor thesis I deal with issues of active and passive safety of cars. In the introductory part I deal with the historical development of the safety of motor vehicles and the basic division of security elements. In the second part I present requirements for compliance with homologation regulations in the field of vehicle safety. In the next part the bachelor thesis focuses on the current elements of active and passive security. In the last part of my work, I describe the trends in passive safety of cars.

Protiblokovací systémy brzdové soustavy a systémy jízdní stability vozidel
Fischer, Michael
Master’s thesis deals with anti-lock braking system and systems for riding stabilization of vehicles. Theoretical part of this paper describes active forces on a vehicle with emphasis on the braking process. The next part describes a design of a braking system with anti-lock braking system, and anti-slip regulation, and design of electronic stabilization program. Every subchapter dealing with system also contains a description of its function. Practical part of this thesis deals with measurement of braking with active and no active ABS done with Volkswagen Golf IV. This measurement was done on chassis dynamometer. Measured results describe the process of braking force and braking acceleration or deceleration. In the end of the thesis is comparison of results of braking with ABS for different pressure inside of tires.

ESP/ESC Impact to Behavior of Vehicle
Weigel, Filip ; Mrázek, Vojtěch (referee) ; Strnadel, Josef (advisor)
This bachelor thesis focuses on active safety - ESP. System ESP greatly improves stability of vehicle while turning. The thesis analyses modelling, brake functionality, subordinate systems of ESP - ABS and ASR, physical forces and phenomenons, model example, analysis of problem, design of model, implementation of model and experiments evaluation of implemented model in UPPAAL enviroment. The goal of the thesis is to prove that ESP system helps to stabilize vehicle while turning by simulation of vehicle model. Results are presented in well-aranged graphs side-by-side. It is possible to analyze the behaviour of vehicle while turning with ESP or without ESP.

Distributed Control System with Dynamically Evolvable Nodes
Křek, Radim ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This thesis describes creation of dynamically evolvable node, which will cooperate with other nodes. Group of these nodes will then create a distributed control system. The MQTT protocol is used for communications purposes between individual nodes. As hardware platform is used ESP32 and ESP8266. Whole operating system is written in MicroPython and supports a live uploading of user applications written in the same language. Later in thesis is decribed creation of monitoring node on Raspberry Pi, which control network. Complete system can be then used to control a intelligent house.

Sensors for driver assistance systems
Ptáček, Martin ; Čala, Martin (referee) ; Beneš, Petr (advisor)
This bachelor thesis is devoted to vehicle stabilization systems, especially to the Anti-lock Braking System ABS, Anti-Skid Regulation ASR and Electronic Stability Program ESP. The main emphasis is placed on sensors needed for implementation of these systems and their required parameters. Findings learned are applied for the implementation of the stabilization system in the model car of the scale 1:10. The relation between the quality of measured sensor data and quality of the resulting stabilization is analyzed using model platfrom testing.

Design of Intelligent Network Module for 2D Radiation Data Acquisition
Lelek, Martin ; Polášková, Lenka (referee) ; Wilfert, Otakar (advisor)
This thesis describes about theoretical design and practical realization of self-contained module for intensity and absorbed dose measuring of X-Radiation from High Voltage X-RAY industrial sources. In the first part, thesis is focused on ways and solutions of radiation protection and principles of measuring absorbed dose and intensity of radiation and possibilities of sending measured data through sensor networks. In the second part, the complete schematic of measuring module is solved, critical blocks are tested and design of PCB is done. Detection circuit, blocks for optical and acoustic signaling, power management and control of the entire device are designed. Detection circuit uses a GM Tube. Next, main box of whole device is designed and made by 3D printing technology. The next step is putting hardware into operation and writing test firmware included verification of wireless communication through WiFi.

ESP - Developing a Course for Aviation English
Košková, Magdaléna ; Žďárek, Karel (advisor) ; Uličná, Klára (referee)
The diploma thesis deals with the development of an ESP (English for specific purpose) course for aviation English. The theoretical part introduces the methodology for ESP course development, the demands on the teacher and other specifics associated with ESP; the practical part focuses on the contents of the course and its evaluation based on the feedback provided by the teacher and the students. In the conclusion the results of the feedback are discussed and the possible solutions suggested.
