Driver Steering Model for Simulation Algorithms
Tmejová, Tereza ; Zháňal, Lubor (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis deals with the creation of a computation driver model. In the first part, there is an overview on driver models for longitudinal and lateral control. Next, driving maneuvres that could be selected for testing of driver model are described. In the practical part, there is created a computational driver model, whose task is to follow required path. The resulting model is tested on three driving maneuvers - steady turning, moose test and slalom. Finally, this model is tested on the passage of a real track. For all these tracks, a comparison is made and the success of the model is evaluated.

Design and evaluation of vehicle steering controller
Margetaj, Martin ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
V této práci je prezentován a popsán FlexRay komunikační protokol se sběrnicí. Je představeno několik matematických modelů vozidel pro simulaci a pro vývoj řídících systémů. Dále je popsána tvorba signálové brány pro testovací vozidlo. Software pro úpravu signálu je implementován a odzkoušen v testovacím vozidle. Matematick0 modely byli parametrizovány aby odpovídali skutečnému vozidlu. Vyvinuté řídící systémy pro ovládání vozidla skrze losí test byli implementovány do automobilu a jejich vlastnosti byli otestovány. Závěrem jsou prezentovány výsledky testů jednotlivých řídících systémů.

Simulation models of human operator.
Boháč, Petr ; Horák, Karel (referee) ; Havlíková, Marie (advisor)
This paper deals with simulation models of the human operator controlling lateral position of simulated vehicle. I am comparing parameters and quality of the McRuer human driver model and the PID controller. Simulated system is single-track vehicle model. Simulated driver is tasked to pass a Moose test with this vehicle model. I am using the simulated annealing method to find optimal parameters of the driver model and then I visualize realized test in 2D and 3D visualization. In the end of this paper I compare simulations of the driver models and assess achieved results.

Influence of Powertrain Type on Vehicle Dynamics
Haniška, Jan ; Semela, Marek (referee) ; Bilík, Martin (advisor)
The aim of this master’s thesis is to assess the influence of the vehicle’s powertrain concept on its driving dynamics. The assessment is carried out with the help of data obtained during driving tests done with test vehicles. As a testing cars were choosen 3 Hyundais Kona with different powertrain types, classic internal combustion engine, a hybrid and a purely electric. Performed tests were the so-called moose test, acceleration, deceleration and it was measured center of gravity for all vehicles too. From the data obtained during individual tests, it was subsequently assessed the influence of the vehicle powertrain type on its driving dynamics.

Analysis of the electronic driving assistants
Vinecký, Radek ; Pexa, Martin (advisor) ; Pavlů, Jindřich (referee)
This bachelor thesis deals with active and passive safety systems in the automotive industry. The thesis describes the individual components of active and passive vehicle safety. The individual chapter deeply analyzes the most commonly used electronic driving assistants with a description of the individual parts and principles of the operation systems and their influence on the behavior and performance of vehicle. It also describes some sensors cooperating with the driving safety assistants. At the end of this chapter is described a future electronic driving assistant.
Within the statistic of the road safety was executed an analysis of the accidents in the years from 2000 to 2015 and evaluated a current trend of the accidents in relation with constantly increasing number of the registered vehicles.
The conclusion evaluates the general view of road traffic safety.
