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.

New Technologies in Transportation
Šimon, Daniel ; Rujbrová, Šárka (referee) ; Smutný, Milan (advisor)
Elektrické vozidlo je lepší náhradou vozidla s vnitřním spalováním, zachovávaje si svůj účel. Elektrické vozidlo nabízí vylepšení výkonu, může vyprodukovat maximální výkon během sekund, bez potřeby převodovky, čímž minimalizuje ztráty na výkonu. Jednoduchý dizajn motoru s jedinou pohybující se částí snižuje náklady na údržbu a celkové opotřebení. Tepelní účinnost vozidla s vnitřním spalováním činí 38 %, v porovnání s 90 % efektivitou proměny elektrické energie na výkon, ukazuje to dominanci elektrického vozidla, v případě že se jedná o výkon a možnosti motoru. Je známo, že vozidla s vnitřním spalováním znečisťují životní prostředí svým procesem spalování, produkcí 67 tun oxidu uhličitého za celý svůj životní cyklus, v porovnání s elektrickým vozidlem, které přímo svým chodem neprodukuje žádné emise, jehož výrobní emise a emise z elektrické výroby, jsou nižší o 50 %. Spolehneme-li na čistší zdroje energie, emise na životní cyklus vozidla mohou být sníženy až o 300 %, nahrazováním znečisťujících tepelných elektráren, čistšími zdroji elektrické energie. Z hlediska bezpečnosti v dopravě, od roku 2001 zaznamenala Evropská unie více než 50% snížení úmrtnosti na cestách s prosazováním pokročilých asistenčních systémů pro řidiče. Má v zájmu tuto úmrtnost dále snižovat testováním a zaváděním nových systémů (eCall, systémy pro předcházení kolizím, …). S pokročilými asistenčními systémy pro řidiče je veřejnost jen pár let od prvních autonomních vozidel, která mohou zlepšit způsob cestování, jak ho nyní známe. Jsou limitovány pouze jejich bezpečností, technologickými chybami a zákonnou odpovědností.

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.

Passive safety and influence of information technology
Mík, Josef ; Kovanda, Jan (advisor) ; Šatochin, Vladimír (referee)
Dissertation thesis deals with problems associated with information system focused on the developed pan-European emergency call system eCall. An improvement in the area of road vehicle safety through a better description of the traffic accident by eCall system are being solved in the dissertation. The work is focused on the frontal collision accidents of type M1. In the first part of the work, a current state of eCall system is described including architecture of the system and overview of related legislation. Further, a legislation related to the vehicle passive safety tests and methods of their evaluation are described. An overview of frontal collision tests with different collision obstacles is presented in the next part of the work. Results of these tests are further used in the analysis of accident severity estimation by eCall system. The works further studies suitability to use the data measured by the eCall system during an accident for the accident severity estimation. This study is based on the correlation analysis of measured accelerations and analysis of parameters of tested eCall unit.

Project eCALL from point of view of infomatics and forensic engineering
Rak, Roman ; Zrubák, Róbert
In the near future, your new car will have an electronic safety system automatically calling emergency services in case of a serious accident. Even if you are unconscious, the system will inform rescue workers of the crash site's exact whereabouts, and the rescues will be on its way within minutes. The system, which has been baptised "eCall", is going to work all over the European Union. It will soon be rolled out across the EU plus Iceland, Norway and Switzerland. As soon as the eCall device in your car senses a severe impact in an accident, it automatically initiates a 112 emergency call to the nearest emergency center and transmits it the exact geographic location of the accident scene and other data. With the same effect, eCalls can also be made manually, at the push of a button. This is convenient if, for instance, you become witness of an accident. Whether the call is made manually or automatically, there will always be a voice connection between the vehicle and the emergency call centre in addition to the automatic data link. This way, any car occupant capable of answering questions can provide the call centre with additional details of the accident. This article describes project eCALL from point of view of car identification and relations to car’s registration information systems.
