Telemetry for Dragon IV Formula
Bezdíček, Jan ; Petrlík, Jiří (referee) ; Šimek, Václav (advisor)
The aim of this master's thesis was to design and construct complete telemetry system for the student formula Dragon IV constructed for international Formula Student competition. At first, the work deals with the measurement of the physical quantities, telemetry system and automotive sensors of the formula, their mutual communication and communication with the CAN bus. It also describes the procedure of hardware design including choosing right inertial sensors and a GPS module and their using in telemetry system. The work contains materials for production of two-layer printed circuit board extending the microcomputer BeagleBone Black on the inertial sensors and the GPS module. The bigger part of the telemetry system is the firmware for hardware and software for the computer user. Both written in programming language C++ and C# are included in this work as well. This user application serves for wireless receiving data from the hardware and their showing and logging. In addition this user application can be used for wireless hardware configuration. The final product is the complete telemetry system and it is suitable for selling to end customer.

Active aerodynamic components of road vehicles
Stiborová, Dana ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
In this diploma thesis active aerodynamic components are designed, specifically brake cooling duct and active automotive wing. Cooling duct prototype and also active regulation controlling electronics including the software were created. Road test was performed to measure the duct parameters. Construction design and the active regulation function of the automotive wing were created. The influence of the wing on aerodynamic characteristics of the car was determined.

Remote Monitoring of Selected Vehicle Subsystems
Drahovský, Peter ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
This thesis describes the concept and realization of embedded system and cloud application, which is designed for remote monitoring of car subsystems over CAN bus. There are written several ways of getting information from car subsystems and process of decoding messages sent over internal car bus. Data gathering is realised by device based on ESP32, which is sending them to cloud application using wireless networks. Application UI is adapted for mobile devices and serves views containg current and historical gathered data.

Experimental workplace for research of car speed limiters
Kubát, Michal ; Možný, Radek (referee) ; Pokorný, Jiří (advisor)
The bachelor’s thesis deals with the issue of remote vehicle speed limitation. The aim of this work is to develop an experimental workplace where the speed limitation using connection to CAN bus will be tested. In the theoretical part, a research on existing solutions of speed limiters is conducted and their protocols and technologies are described. The theoretical part also includes a research and description of possible threats and attacks on technology ITS-G5. The practical part deals with the development of the experimental workplace that consists of an OBD-II simulator and a transmitter. The OBD-II simulator includes Arduino UNO and add-on modules, its communication is realised via CAN bus. Transmitter includes Arduino NANO. Then, a wireless communication between a transmitter and an OBD-II simulator on 433 MHz and the wireless speed adjustments are developed. Finally, the IVIM message is designed and implemented for car speed limitation. Its structure was selected according to ISO standards for communication in ITS-G5 technology. The implementation of this message was tested on an OBD-II simulator. On the whole, a complete experimental workplace was assembled, and its manual was created.

Data diagnostics in modern car control units
Hájek, Ondřej ; Vítek, Richard (referee) ; Prokeš, Aleš (advisor)
Presented Diploma thesis is aimed on design and implementation of car diagnostic interface of engine control units EDC. Diagnostic interface provide communication between car and computer by USB interface. User will be able to task commands by developed computer application. For developing application is necessary to get information about used protocols and basic knowledge in car’s hardware. Understanding OBD2 standard and communication protocol CAN, eventually KWP is necessary for design the solution. Main purpose of this thesis is to store enough usable information about car diagnostic for future continuation.

Modular Display System with LED Diodes
Fňukal, Jiří ; Crha, Adam (referee) ; Šimek, Václav (advisor)
The purpose of bachelor thesies is to create a modular display system with LED diodes. The work is divided into three main section. The first section deals with the description of the LED systems available on the market, also contains a description of development platforms. The second part of this work focuses on the industrial buses, with an emphasis on the CAN bus. In the last section is described the design and construction of the LED system. After reading this work, the reader should be able to navigate in LED systems, industrial communication buses and should be able to construct this LED system.

Real-Time Operating System with Fixed Task Priority for Raspberry Pi
Kolář, Josef ; Peringer, Petr (referee) ; Janoušek, Vladimír (advisor)
The main goal of this work is to create a support for an open-source real-time operating system on the computer Raspberry Pi 3B+. The project FreeRTOS is selected as a great candidate for further work. The runtime environment and support for user-space applications are presented. Two demonstration applications serve as proofs of support, the first one uses two periodic tasks and reports their state to the serial interface. The second demonstration application runds the same periodic tasks, but reporting the state is done using the CAN bus, for which is the driver realised. The result of this thesis is a working system FreeRTOS for Raspberry Pi 3B+ computer with support for time-critical usages.

Application for Data Acquisition and Processing from OBDII Interface
Kabelka, Michal ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
This thesis is focused on obtaining data from a car via the OBDII interface. A successive analysis of the measured values, car sensors, control systems and communication principles between them is done. Basic principles for creating Android mobile applications have been also summarized here. However, the main focus is on designing an application which uses a microcontroller ELM327 to communicate with the electronic systems of a real car. The application shows the obtained data in a form that enables the driver to improve his/her driving habits in terms of fuel economy. The application also demonstrates communication with a car outside of the OBDII standard, in this scenario, by controlling a built-in radio in the car.

Multiple-funktion steering wheel Formule Student
Paulus, Luboš ; Štohl, Radek (referee) ; Havlíková, Marie (advisor)
The Master‘s thesis deals with a creating of display writers on multiple-function steering wheel Formule Student. It is mainly about dates transfered through RS232 or CAN bus from control unit of the Formule to microcontroller. First of all it is necessary to find out, which informations and a which way of displaying them are more useful and readable for drivers. This leads to another point - right choice of display writers, which will be used on the steering wheel. Creation of the design and construction of display device follows.
