Wireless OBDII-Bluetooth Interface
Bezdíček, Jan ; Šimek, Václav (referee) ; Bartoš, Pavel (advisor)
The goal of this bachelor's thesis was to design an OBDII interface, which would have been able to communicate with a PC through Bluetooth interface. Designed wireless interface is able to diagnose all OBDII equipped vehicles, but the vehicles have to communicate by some of the supported protocols. It is possible to communicate with a vehicle using a software application or by simple commands in data terminal as well. Main parts of the device are a proprietary ELM327 microcontroller and an industrial Bluetooth module. The built-up device has been tested and it is able to display right values of vehicle sensors and to operate diagnostic trouble codes as well.

Testing of the Common-rail pressure regulation valve by ADwin device
Šoulák, Vojtěch ; Svída, David (referee) ; Kučera, Pavel (advisor)
Tato diplomová práce se zabývá rozšířením testovacích možností vývojové stanice pomocí zařízení ADwin. Hlavní částí diplomové práce je navržení přídavného okruhu testovací stanice a naprogramování testu pro tlakový regulační ventil. V další část se diplomová práce zabývá předpokladem stavu komponent regulačního ventilu po testování. Při porovnání tohoto předpokládaného stavu a reálném stavu po testování je ověřeno správné naprogramování testu a správná funkce nově navrženého okruhu.

Inovation of System for Automated Integrational ECU Tests
Kyloušek, Josef ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
This master's thesis deals with the issue of software tools for automated integrational ECU testing. It is specifically focused on TestAut 2 tool, which is developed by e4t company and used for testing of Skoda cars. Goal of this thesis is comparison of TestAut 2 against similar tools used in automotive industry. This work contains analysis of TestAut 2 tooland description of principles and features of EXAM, MODENA and PROVEtech tools. Set of principles considerd as advantageous is chosen from collected information. Next part of this thesis describes implementation of chosen principles to TestAut 2 tool, verification ofit's functionality and evaluation of it's benefits. In the conclusion author suggests another improvements that can be done.

System for Transmitting Diagnostic Data from the Car
Uhliar, Martin ; Vašíček, Zdeněk (referee) ; Goldmann, Tomáš (advisor)
This diploma thesis deals with the design and implementation at the software and hardware level of the device, which is used for communication and acquisition of diagnostic data from the car control unit. The acquired data can be stored on the device and also sent via LoRa technology and TheThingsNetwork to a database on a remote server. NB-IoT technology is used for data that needs to be obtained in real time. The recorded data is presented in the form of a mobile application, which displays the obtained data to the user and can notify him of a problem with the vehicle. The device communicates with the car via the CAN bus using the OBD2 protocol and is controlled by an ARM microcontroller.

Predicting spark-ignition engine emissions
Jirout, Petr ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This diploma thesis deals with the possibility of predicting emissions of SI engines. The aim was to create an algorithm for predicting unburned hydrocarbons and carbon monoxide, based on ECU signals. The algorithm is based on practical experiments with SI engines. In the summary, the issues and the possible use of the created algorithm following the incorporation of EU7 are outlined.

Mobile Signal Generator for ECU Calibration
Pauliuchenka, Aliaksandr ; Kučera, Pavel (referee) ; Svída, David (advisor)
The subject of this thesis is a mobile electrical signal generator for the calibration of an Electronic Control Unit (ECU). The thesis primarily offers an analysis of the electrical signals that enter the control unit. It then describes the process of developing the Printed Circuit Board (PCB) used in the generator, the C++ programs for the microcontrollers used, and the software for controlling and programming the test scenarios. Finally, the thesis concludes by measuring the output signals of the generator with an oscilloscope and testing the connection to an open ECU. Based on these tests, the functionality of the generator was evaluated.
