Inovation of System for Automated Integrational ECU Tests
Kyloušek, Josef ; Orság, Filip (referee) ; Drahanský, Martin (advisor)
This master's thesis deals with the issue of software tools for automated integrational ECU testing. It is specifically focused on TestAut 2 tool, which is developed by e4t company and used for testing of Skoda cars. Goal of this thesis is comparison of TestAut 2 against similar tools used in automotive industry. This work contains analysis of TestAut 2 tooland description of principles and features of EXAM, MODENA and PROVEtech tools. Set of principles considerd as advantageous is chosen from collected information. Next part of this thesis describes implementation of chosen principles to TestAut 2 tool, verification ofit's functionality and evaluation of it's benefits. In the conclusion author suggests another improvements that can be done.

Design and implementation of testing unit for small series production
Kolomazník, Vojtěch ; Krejsa, Jiří (referee) ; Hrbáček, Jan (advisor)
The goal of the master´s thesis is to design testing unit for small batch production. The background research part introduces testing principles, we are also discussed different ways of realization of testing connectors and choice of control unit. The work also describes the design of the hardware wiring and mechanical design. The result of this thesis is a device implemented according to the proposal described in the work. No significant fault was found during operation of testing unit, which verified its reliability and full functionality. The work also includes a description of the software implementation in Python.

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.

Hardware-in-the-loop simulation with using xPC target toolbox
Benko, Boris ; Dolák, Petr (referee) ; Klusáček, Stanislav (advisor)
The submitted thesis „Hardware-in-the-loop simulation with using xPC Target toolbox“ deals with the using of xPC Target toolbox in conjunction with data acquisition card from National Instruments PCI-6259 for testing diagnostic embedded devices, using hardware-in-the-loop method. In the first part of the thesis, the importance of application of the method to the model based design is discussed. As a demonstration, the specific method is framed, tried out and used for testing the real ECU. The data from the simulation are gathered using the xPC Target, the results are subsequently compared to the data from the documentation of the fuel injection system Bosch Mono-motronic. This whole process is described in the second part of the thesis.

Methodes of vehicle technical condition verification
Urban, Zdeněk
It hase been neccessary to verificate mediated or inaccurate worshop staff information during the vehicle technical condition evaluation process. Electronic controls of different vehicles´ systems and the newest diagnostic procedures permit to carry the rapid tests and measurements out. The expert with regard to his professionalism has to be informed about particular diagnostic procedures and would know to analyse the reset of measurements. Electronic control unit hasn´t been the fault memory only, it permits the important diagnostic operating data download, active test or self-starting kontrol precedures. As an example this material introduces the different methodes of engine compression tests and measurements – by means of compression-meter, oscilloscope and electronic control unit diagnostic software.

The Application of Data from Vehicle Electronic Control Units in the Analysis of Road Accidents
Švábenský, Petr ; Tylšar, Vladimír (referee) ; Panáček, Vladimír (advisor)
Abstract Master thesis is focused on The Application of Data from Vehicle Electronic Control Units in the Analysis of Road Accidents. The theoretical part deals with the electronic systems of vehicles and their control units, diagnostic processes, retrieving accident data from the controls unit and the need for these data in the analysis of road accidents. The experimental part focuses on obtaining data for crashed vehicles, interpretation of such data and assessment of their usefulness for analyzing road accidents. It also focuses on the procedures and methods on how to retreive accident data.

Design of test environment for automatic testing of eletronic control unit
Dalecký, Filip ; Andrš, Ondřej (referee) ; Kovář, Jiří (advisor)
This master’s thesis deals with the design and implementation of part of test environment for automatic testing of electronic control unit in the production. The electronic control unit is manufactured by UNIS, a.s. and is used as a control and power electronics for the hydraulic unit. The theoretical part of the thesis deals with the development and automatic testing of electronics in the field of aerospace engineering. The practical part describes the proposed automatic test environment and implementation of testing software using hardware and software products by National Instruments. The main platforms used for software development are LabVIEW and TestStand. Created test environment is finally verified by testing several control units.
