RGB MATRIX LED system
Sikora, Roman ; Fedra,, Zbyněk (referee) ; Hudcová, Lucie (advisor)
The bachelor thesis deals with the development of a control software for the rear RGB LED lamp, which allows to design and display any color schemes. The first part of the work aims at development of complete Raspberry Pi 3 control software. Next thing which the thesis deals with is design of user interface for Windows platform for easy creation of color schemes which includes typical functions for a rear lamps like a tial, stop, reverse, fog, direction indicator, coming home and leaving home. Next part of the work is implementation of the control for the model via CAN bus which is used in automotive technology, and to develop the control software for Windows platform. In the project the whole model with Raspberry Pi is tested for Conducted emissions.

The Use of Inerter in Vehicle Design
Lanzendörfer, Tomáš ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis deals with the inerter application in vehicle’s suspension. The aim was to perform a theoretical analysis of its features, to compare its construction layouts, to create a multibody model of the car’s suspension and to analyse inerter’s effects while performing different driving manoeuvres. All analyses were performed by MSC Adams View software with a little support from Matlab. The quality of ride comfort and accessible traction force were increased by the inerter almost in every case, and dynamic load of the suspension was also decreased in some cases. The inerter is a device with high potential, but with high purchase costs as well, so further development and practical research is necessary.

Driver monitoring
Pieger, Matúš ; Bilík, Šimon (referee) ; Richter, Miloslav (advisor)
This master’s thesis deals with the design of systems for data collection which describe the driver’s behaviour in a car. This data is used to detect risky behaviour that the driver may commit due to inattention caused by the use of either lower or higher levels of driving automation. The thesis first describes the existing safety systems, especially in relation to the driver. Then it deals with the design of the necessary measuring scenes and the implementation of new systems based on the processing of input images which are obtained via the Intel RealSense D415 stereo camera. Every system is tested in a real vehicle environment. In the end the thesis contains an evaluation regarding the detection reliability of the created algorithms, it considers their shortcomings and possible improvements.

Use of 3D printing in the production of functional prototypes for automotive
Mikulášek, Marek ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This thesis deals with the 3D printing of composite materials. The constant development of this technology has enabled the application of this method for the production of prototypes, but also functional components. The theoretical part deals with the study of composite materials and the principle of production using additive technology. In the practical part, an analysis of the suitability of part processing using the 3D printing method is performed on a specific component and than applicated to the assembly hall located in ŠKODA AUTO a.s.

DC-DC converter for matrix beam module
Sikora, Roman ; Dobesch,, Aleš (referee) ; Hudcová, Lucie (advisor)
The master thesis deals with the development of buck-boost DC-DC converter which supplies matrix beam module. The design is focused on testing two-phase boost converter and three channel buck converter manufactured by NXP Semiconductors. Part of the design is implementation of microcontroller for converter control and communication with computer. Part of the thesis is also to design user interface on Windows platform for easy system configuration. Next thing the thesis deals with is designing load for DC-DC converter that is variable and can make different current consumption. One part of this thesis is focused to achieve the lowest conducted emissions and to maximize conducted immunity. Part of this project is production of a prototype and prototype testing.

Thermal dissipation optimization of LED Driver devices NCV78964 and NCV78925
Rejthar, Martin ; Boušek, Jaroslav (referee) ; Prokop, Roman (advisor)
Thesis is aimed at automotive DC/DC convertor analysis. It introduces categories of DC/DC convertors by their architecture. Converters are then divided to step-up and step-down. Later the types of power losses are introduced. Theory is closed with thermal design rules and cooling of integrated circuits. After basic convertor analysis, one specific Integrated Circuit is described in more detail. Especially its principles of operations and this IC is used in an evaluation board. Thesis predicts the thermal parameters of modules and these results are compared with measured data, acquired on modules, that were designed too.
