Mechanical-hydraulic model of vehical energy regeneration
Pisklák, Jan ; Vrbka, Martin (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis is a research about mathematic-physical model of vehicle’s kinetic energy regeneration. Mr. Pourmovahed A. et al. were dealing with this problem. He used the method of the determinated thermal time constants. Pourmovahed continued in study reports written by Green W. L. and Otis D.. His scientific work covers the analytical treatment which is compared with an experimental tests.

Models of vehicle´s kinetic energy recovery
Fic, Miloslav ; Vaverka, Michal (referee) ; Nevrlý, Josef (advisor)
The bachelor thesis deals with analysis of existing knowledge in the area of vehicle kinetic energy recuperation models. This analysis is mainly focused on hydrostatic regenerative braking system models. This paper introduces stances of some authors, mathematic relationships and program tools useful for simulation of these models. Afterwards is estimation of shown studies and at least is presented future development of hydrostatic regenerative braking systems. This paper gives a sight of hydraulic recuperation system problems and it could be used as the theoretical element for next research in recuperation models area.

Mathematical Modelling of Vehicle Fuel Consumption
Dražka, Jan ; Novotný, Jan (referee) ; Popela, Pavel (advisor)
This bachelor’s thesis deals with a model building of vehlicle’s model based on real data and with a modelling of it’s movement and it’s fuel consumption. The thesis includes a preparation of input data as well as model building. The main aim of the thesis is the comparison among selected driving modes from the point of fuel consumption and it’s optimization. This comparison is simulated in MATLAB environement and GAMS with the use of selected optimization algorithms.

Sport downhill cart for the disabled
Šantavý, Ivo ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor´s thesis deals with the development of a "Sport downhill cart for the disabled" prototype. This project was jointly inspired by Human Power Vehicles and by components from various industry sectors. After a description of the above mentioned vehicles, the work describes the successive development of the cart, including construction solution, and a component and frame modeling in the CAD system Autodesk Inventor. The total calculation of the entire "Sport downhill cart for the disabled" is presented in the conclusion.

Current situation of research into interaction of tire with surface
Kleger, Ondřej ; Kašpárek, Jaroslav (referee) ; Pokorný, Jan (advisor)
Modeling and simulation belong to very important tools used in automotive industry of present days. Simulation forms basis for both – new vehicle development and also improvement of vehicles already in production. A key role of simulation may be seen in the development of vehicle active safety features such as “Anti-Block System” (ABS), “Anti-Slip Regulation” (ASR), “Electronic Stability Program” (ESP) etc. As a common feature, all of the listed systems require accurate simulation of the interaction between the tire and the road surface. Thanks to simulation tools we can model driving situations and behavior of the whole system so that it nearly mimics real behavior of the vehicle on the road. Nevertheless; despite continuously increasing accuracy of the simulation tools, a development process still cannot be completed without real tests and measurements on tires and road surface characteristics.

Study of automated parking systems
Peprník, Pavel ; Malášek, Jiří (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis summarizes the current knowledge on modern automated parking systems. It's a very interesting idea of solving the lack of parking space for the ever growing number of cars. This thesis describes basic types of these systems, their use, technical and operating parameters, structural and technological possibilities of manipulation with cars. This thesis also contains examples of already implemented projects, both in CR and abroad. It mentions advantages and disadvantages of these systems. In the end of this work are showed possibilities of using these technologies in the future.

Accumulation of energy
Neuman, Tomáš ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis comprises a technical retrieval of overview of energy accumulation usable in cars. The basic characteristics and problems of particular kinds of accumulators and ways of accumulation are brought in this thesis, describing characteristics of lead accumulator, the structure and composition of electromobiles and appropriate batteries. In the following part the description of heat and hydrogen accumulator is stated. The end of this bachelor thesis is dedicated to mechanical accumulator.
