Experimental validation of active flow control concept for automotive applications
Sobotka, Vojtěch ; Jebáček, Ivo (referee) ; Popela, Robert (advisor)
Tato diplomová práce obsahuje komplexní návrh systému aktivního řízení proudu instalovaného na osobním voze Škoda Roomster. Tato práce navazuje na výzkum provedený VUT a TUB na vozidle Volkswagen UP! Návrh lze rozdělit na tři základní části - návrh spoileru, návrh závěsů a návrh vyfukovacího systému. V každé z těchto částí je návrh detailně popsán a potřebná výkresová dokumentace je součástí práce v její příloze. Pro potřeby návrhu vyfukovacího systému bylo provedeno jeho testování. Výsledky testu jsou v této části uvedeny. Práce také obsahuje komplexní popis sestavení celého systému a jeho instalace na automobil.

Post-war automotive aerodynamics
Šmerda, Ondřej ; Vančura, Jan (referee) ; Čavoj, Ondřej (advisor)
This Bachelor thesis deals with charting the development of the automotive aerodynamics in the post-war period. It focuses on principles that go along with car design. The development is demonstrated by aerodynamically significant and unusual cars including racing and record cars. Last but not least, the work compares those cars with today's cars and describes drawbacks of the cars of the given period from today's perspective.

Moving object detection
Škuta, Pavel ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this these was devise a automatic system applications, monitoring entering of motors vechitles with in automaric collection of trafic data. Automatic system allows identify of mooving vechitlses in slow speed and searching of the area registration number. Theoretical analysis of possible kind solving problems detection moving vechitles and their localization. From possible solutions was selected solution by camera systems. Was take a pictures of vechitles, whitch is as true of the real scene. On the pictures was testing of algorithm for detecting of area registraction number of vechitles. Designed system is possible to use for automatic monitoring mooving entering vechitles.

Styling of the passenger car Proton Prevé
Burjeta, Josef ; Karásek, David (referee) ; Škaroupka, David (advisor)
The thesis is focused on styling a real passenger car Proton Prevé with regard to the quality of surface modelling using computer software Autodesk Alias. The stylistic adjustments were made on basis of the background research and poll focused on the target group. Selected body parts have been modified according to the desired sport character of the car and the current vehicle’s appearance. The result of the work is a surface model, which was created using A-Class modelling methods under the direction of Evektor company. The benefit of the thesis is facelift of an existing car with consideration of the current market situation and customer requirements.

Design of a test rig for a wear test of inner ball joints
Blecha, Martin ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This diploma thesis deals with the design of several variants of test rig for tests of axial ball joints of passenger cars. The individual design variants are evaluated based on the evaluation matrix and then the best option is selected. Selected proposal includes a complete design including 3D models and strength analyses that focus on the most stressed construction nodes. These design nodes are solved using the finite element method. Hydraulics and hydraulic elements are equipped by the existing equipment from a test lab. At the end of this thesis is solved risk analysis of the new construction and its economic evaluation.

Transaxles of modern vehicles
Okáník, František ; Blaťák, Ondřej (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is focused on comparing the properties of axles used in modern passenger cars kinematics of wheel suspension and advantages and disadvantages of their construction. The thesis also includes a description of each of the axle component, their construction and function. Part of this thesis is focused on the description of race car axles and their design differences between passenger cars. Final chapter is devoted to several interesting and innovative axle components that are significantly different than standard components.

The beginnings of automotive aerodynamics
Sunek, Ondřej ; Vančura, Jan (referee) ; Čavoj, Ondřej (advisor)
This bachelor thesis is concerned with charting the early phase of development of automobile aerodynamics around the first half of the 20th century. Further on, it describes some procedures which were used for designing of each car and the circumstances that led to the design of breakthrough cars. Simultaneously the thesis states some aerodynamic deficiencies of the cars of the period as viewed from today´s perspective.

Analysis of Driving a Passenger Vehicle with a Trailer
Šujan, Tomáš ; Kropáč, František (referee) ; Vémola, Aleš (advisor)
The subject of this thesis is the analysis of the negative effects associated with the operation of a trailer for a personal vehicle with respect to the design speed, technical checks and analysis related legislation. Its work is drawn from the measurement, cooperation with leading Czech production plant trailers Vezeko s.r.o., an organization engaged in the implementation of engineering controls DEKRA Automobil a.s. and available literature, including electronic resources. Results of the work end with proposals for specific measures to minimize the identified adverse effects.
