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.

Wireless gathering of diagnostic data of cars supporting OBD-II
Fadrný, Jaroslav ; Kořínek, Tomáš (referee) ; Raida, Zbyněk (advisor)
Read up protocol OBD-II and familiarize yourself with the concept of existing devices, which use this protocol for wireless data transmission diagnostics car. Different conception mutually compare and suggest own concept device. The device should be consist from standard components without development own hardware. Implement the proposed device. Verify function of device and measure its range and data throughput. Discuss the connection to the database server and simple presentation of data.

EURO 6 Emission Standards
Velešík, Aleš ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
Bachelor´s thesis is focused on the approach the issue of Euro 6 emission standards. There is a general description of the tests, which the manufacturer must undertake and successfully complete to produce cars at this emission level. There is also a description of the harmful substances produced from the exhaust system of a car and an overview of the structural elements to reduce them. In conclusion, the reflection on the issue of emission standards and their constant tightening.

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.

Pesonal car operation monitoring using maintenance servis connector.
Muška, Radomír ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
This project produced within The Bachelor’s Study Programme of Applied Sciences in Engineering presents the of a full-value service diagnostics for motor cars. This diagnostics was draft on the basis of the profesional service diagnostics study, the CAN Bus, the OBD and EOBD Standards. The diagnostics puts the programmed VAG-COM Environment (the Roos Tech Company’s product) to use. This method is low-cost and does not make use of professional appliances. The draft diagnostic cabe lis the OBD Standard compatible.

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.

Diagnostics of modern vehicles
Holeš, Cyril ; Pech, Ondřej (referee) ; Štětina, Josef (advisor)
Diagnostics of vehicles has become an important part of testing, control and developement of vehicles. The aim of this bachelor´s thesis is to summarize and compare the possibilities of diagnostics of modern vehicles. The first part of thesis focuses on the development of diagnostics, advantages and disadvantages of each type of diagnostics, review of the information obtained before the OBD II diagnostics and the list of standards and communication protocols. In the next part it compares the possibility of certain diagnostics in practice.
