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.

Design of a rescue button for emergency calls in cars
Jarabý, Šimon ; Jeřábek, Jan (referee) ; Dvořák, Jan (advisor)
This bachelor’s thesis focuses on the design and implementation of a prototype device, which aims to retrofit vehicles manufactured before 2018 with an emergency call sys- tem. The device will operate on similar principles as the eCall service introduced by the European Union. The first part of the work contains a basic acquaintance with the used technologies and procedures in the proposed devices. Since this is a device intended for cars, we perform this retrofit by connecting the device to the OBD-II (On Board Diagnostics) diagnostic connector. For this reason, in the theoretical part we get acquainted with the diagnostic connector OBD-II as well as with the CAN bus, com- munication protocols or the method of accident evaluation. The practical part with the subsequent design of equipment and selection of individual components. We will need to send location and communication from the devices via the 3G network, which is why we choose the Global Positioning System (GPS) and Global System for Mobile Commu- nications (GSM) modules. We will also evaluate the accident using an accelerometer so that we can determine the severity of the accident. The last part of the work describes the practical construction and implemented equipment.

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.

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.
