Electronic speed controller
Šimbera, Michal ; Kučera, Pavel (referee) ; Svída, David (advisor)
The thesis deals with the design, realisation and functional verification of an electronic cruise control unit. Required inputs, outputs and controller of the control unit are identified first. The design and layout of the electronical components, including the processor, power supply and other necessary hardware is discussed. The algorithm for the control unit is developed in C/C++ and thoroughly analysed. The functionality of the cruise control unit equipped with the algorithm is verified through a case study performed on a combustion engine.

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.
