Engine Diagnostic
Holeš, Cyril ; Beran, Martin (referee) ; Svída, David (advisor)
The thesis is focused on determining the methodology of engine diagnostics for vehicles with common rail direct fuel injection. The first section describes the communication between the diagnostic tools and control units, and the common rail system for diesel engines. The next section specifies the procedure for the acquisition, processing and analysis of data using selective diagnostic tools along with software in a numerical computing environment. Subsequently, from the results, the equivalent electronic control of the fuel injection quantity is established for the purpose of research, vehicle servicing. The results may also allow for additional observations to be made.

Use of VAG-COM PROFI Diagnostic Kit in Forensic Engineering
Wertheim, Adolf ; Tylšar, Vladimír (referee) ; Panáček, Vladimír (advisor)
The thesis deals with possibilities of application of VAG-COM PROFI diagnostic kit in forensic engineering. After defining a theoretical basis, according to possibilities of evaluation of technical condition of a vehicle, the thesis is focused on applying diagnostic methods using above mentioned diagnostic kit. With respect to opportunities of identification of driving parameters, possibility of acceleration measurement and estimation of engine power are introduced. Describing of methodology and making the final statement are contained in the thesis as a part of every single measurement.

Secured vehicle monitoring using OBDII and LPWAN networks
Babeľa, Miroslav ; Mašek, Pavel (referee) ; Možný, Radek (advisor)
Automobily sa s vývojom technológie a vládnych nariadení stávajú viac a viac komplikované. To sa však stáva problémom nie lel pre individuálnych majiteľov vozidiel ale aj pre prevádzkovateľov flotíl, kde sa im zvyšujú náklady na údržbu a prestoje. Aby majitelia vozidiel mohli znížiť svoje náklady na minimum, mali by mať nainštalované jednoduchej monitorovacie zariadenie, ktoré ich môže upozornit na potenciálne problémy a predísť tak oveľa nákladnejším opravám. Cieľom tejto práce je vytvoriť zariadenie, ktoré sa umiestni pevne vo vozidle a bude monitorovať a odosielať doležíté motorické parametre na vzdialený server pre ďalšie spracovanie. V teoretickej časti práce sú opísané aktuálne OBD nariadenia, používané komunikačné protokoly v súčasných autách, dostupné nízkoenergetické siete pre rozsiahle územie (LPWAN) a navigačné systémy (GNSS). Praktická časť sa zaoberá návrhom OBD II ˙monitorovacieho zariadenia, ktoré podporuje najpoužívanejšie komunikačné protokoly v Európe, NB-IoT sieť a systém na určenie polohy. Posledná kapitola analyzuje výslednú cenu zariadenia a opisuje jej prípadnú optimalizáciu pre komerčné použitie.

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.

iOS Application for Driving Data Extraction and Analysis via OBD-II
Pihrt, Patrik ; Beran, Vítězslav (referee) ; Bobák, Petr (advisor)
This project aims to create a mobile application for iOS devices that provide valuable information about user's car rides. Needed data are obtained by ELM327 located in OBD-II scanner which can communicate with the car. Obtained data are analyzed using table of limits. The application informs riders about their driving mistakes and giving them tips how to fix them. Trips can be saved and exported in the form of logbook. In addition application includes diagnostic functions that can be found in every other diagnostic application.

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.

Car Diagnose Using of OBD module
Sikora, Vojtěch ; Volf, Jaromír (advisor) ; Novák, Viktor (referee)
This thesis deals with the OBD diagnostics, their historical development and current trends. The thesis describes individual technical solutions and principles of their function. There is also a list of devices for testing. The thesis includes economic importance and a simple market research. Then it continues with the testing of the diagnostics itself and of a mobile application. Diagnostics VAG-COM was tested using a personal computer and Diagnostics ELM 327 Modul 1 with an application DashCommand that communicates via WiFi with a smart phone. Everything was done with a Skoda Fabia 1.2HTP with 47kW of power. Testing of the program and application can be a beneficial to the reader, because selected procedures are explained in detail.

Návrh laboratoře pro diagnostiku strojů
SVOBODA, Jakub
Diagnostics as such stands side by side with machine repairs in all sectors. Diagnosing faults or damage is the first step of each repair. In this thests I introduce the history of diagnostics and basic diagnostic equipment for diagnostics of cars and agricultural machinery to the readers. The main theme of this work is a detailed project of a diagnostic laboratory with diagnostic equipment, including all furniture and machinery equipment. It also contains a plan for build a laboratory and layout. The result is a complete price calculation suitable for a grant support.
