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.

Optimization of thermal dissociation atomic hydrogen source for use SEM
Melichárek, Václav ; Polčák, Josef (referee) ; Mach, Jindřich (advisor)
The focus of this bachelor's thesis is the optimization of a thermal dissociation monoatomic hydrogen source. The project entailed the design and construction of a new control electronics for the thermal dissociation source, because the source has been powered using universal laboratory power supplies until now. The thesis begins with a brief introduction into the interaction of graphene with monoatomic hydrogen, the operational principle and construction of the monoatomic hydrogen source. Furthermore, the requirements on the design of the electronics are specified. A more detailed analysis of possible solutions, and the selection of the optimal solution were also conducted. The practical part discusses the conceptual designs in detail and describes the selection of the optimal solution. It follows by elaborating on the implementation of the control electronics in detail, its design and construction, and the electrical circuit in particular.

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.
