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.

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.

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.

On-board Computer Unit with Testing for Cars
Špatenka, Jan ; Navrátil,, Vlastimil (referee) ; Dušek, Martin (advisor)
This thesis deals with the design and implementation of on-board computer unit with testing for cars. The first part focuses on circuit design concepts. Measurement data acquisition module uses standard OBD2. The module is designed based on the measuring circuit STN1110. Measuring module equipped with USB and JTAG communicates with the nearby devices. The control module is equipped with ARM microcontroller. The second part deals with the implementation of software for the microcontroller and the PC application. Finally, test results of the on-board computer implemented are presented.

Smart solution for emergency call in cars
Haniška, Jan ; Štůsek, Martin (referee) ; Pokorný, Jiří (advisor)
This bechoral thesis is focused on design and realization of initial device prototype, which will be able to retrofit older vehicles with the system for emergency calling similar to eCall. Retrofitting is done by connecting the device to the diagnostic connector OBD. First part of thesis describes basic technologies used during device design, as CAN bus, dignostic connector OBD-II, communication protocols used in automotive industry or evaluation method for crash etc. Also there are described general requirements for this device according to European Union directives. Practical part of thesis is aimed at realization of vehicles electronic cotrol unit emulator needed for development. Then there is described device design, where are chosen components like GPS module, GSM modem, accelerometer and development board for control of entire device. Last part of thesis is focused on realization of device prototype. As main component of entire device was chosen development board NUCLEO-F103RB, made by manufacturer STMicroelectronics. During software development were used HAL libraries from this manufacturer. Also were created two new libraries. First library called CAN_data_load is used for communication between vehicles electronical control unit emulator by CAN bus interface and subsequent data processing and second one called GPS_load_control for data acqusition from GPS module and their processing. Finally there is described commissioning and service of created experimental workplace with realized prototype device. For this procedures were created additional instructions.
