FITkit CAN Implementation
Jančo, Tomáš ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
This thesis describes main principles of communication on CAN bus, design and implementation of CAN bus controller. The controller is implemented in VHDL for school development platform FITkit. This work also describes design of CAN physical layer circuits for connecting FITKit to CAN bus.

Diagnostic module for Single-Wire CAN bus
Jež, Michal ; Doseděl, Martin (referee) ; Havránek, Zdeněk (advisor)
The basic properties of the CAN bus are analyzed in the bachelor's thesis. Furthermore, this work deals with the availability of circuits for the implementation of the CAN bus and the physical layer Single Wire CAN. Subsequently, the design of the diagnostic unit for the CAN bus is processed. It also deals with the design of firmware for the diagnostic module and a PC program for subsequent data analysis. Finally, the compatibility of the Single Wire CAN bus with the Low Speed CAN bus is tested.

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.

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.

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.

Possibilities of data analysis from CAN bus
Krišková, Mahulena ; Pančík, Juraj (referee) ; Belák, Michal (advisor)
This Master’s thesis covers possibilities of data collection and data analysis from CAN. Historical background and current trends are described as well as the principle of operation. The aim of this thesis was to provide several methods of data reading and subsequently their possible ways of interpretation for purposes of Forensic Engineering, more precisely, in the terms of vehicle driving dynamics. Owing to the fact the messages on the CAN bus are themselves encoded, one is unable to read them without further decryption. However, the possibilities of decoding are limited. Individual methods of data reading, collection, and analysis are presented. The analysis is focused on the process of data collection form CAN bus and data decryption. From several software options, one was selected as a tool for experimental part.

Analysis of the communication between car's electronic control units
Zouhar, Štěpán ; Matějásko, Michal (referee) ; Spáčil, Tomáš (advisor)
This bachelor thesis has 3 basic parts. In the first part is the main topic testing stand which was made for purpose of developing and testing electronic devices for cars. The next part deals with communication on the CAN bus and interface between tools CANoe and Simulink for simulation purposes of ECU‘s (Electronic Control Unit) behaviour. At the end were created 2 examples: one for CANoe and the second one for interface between CANoe and Simulink.

Energy data monitoring in electric vehicle
Krejz, Jan ; Dedek,, Jan (referee) ; Baxant, Petr (advisor)
The thesis deals with the monitoring of the energy data in an electric vehicle using modern diagnostics, using data readings from the CAN bus. The thesis can be divided into three parts. The first part provides a theoretical introduction to the measurement systems found in electric vehicles, then there are the methods of data transmission within the electric vehicle and the possibilities of how to obtain this data. The second part is an overview energy model that theoretically describes the possible flows of electrical energy within an electric vehicle, this theory is then supported by models in Simulink software for specific situations and tests where the theoretically calculated values of energy consumed were verified using this model. and the measured values. In the last section, a proposal for tests and locations where it would be appropriate to monitor these flows is presented. Some of the tests were performed and then evaluated.
