Continuous and discrete time attitude control of a vehicle
Najvarová, Lucie ; Nechvátal, Luděk (referee) ; Gennaro, Stefano Di (advisor)
Kontrola řízení vozidla se stala významným problémem v automatizačních aplikacích v automobilovém průmyslu. Ta se stala reálnou díky zavedení různých "by-wire" subsystémů, jako je např. "steer-by-wire," "break-by-wire," atd. Tyto subsystémy reprezentují elektronické ekvivalenty již existujících mechanických a hydraulických subsystémů. Především pak může být zavedeno číslicové řízení, určené na základě vzorkování dynamiky vozidla. Výhodou periodického snímání vstupních veličin je vyvarování se určitých poruch spojitého řízení.

Car Driving Simulator
Michalík, David ; Fiedler, Petr (referee) ; Jirgl, Miroslav (advisor)
This master’s thesis is mainly focused on creating our own car driving simulator and basic data gathering from the driver’s input. To achieve this goal, the thesis includes introduction to man-machine systems and basic information about functions and runtime game engine employs. Research about commonly used open source game engines is also presented with a detailed focus on the engine we chose - Unreal Engine. In conclusion ofthis thesis, a full version of a car driving simulator is created with gathered data analysis.

The response of the visual system when driving a car in real conditions and in a simulator during a parallel motor task.
Čiháková, Lucie ; Jelen, Karel (advisor) ; Lopot, František (referee)
Work title: The response of the visual system when driving a car in real conditions and in a simulator during a parallel motor task. Aims: To implement a laboratory measurement in a driving simulator and in real conditions during a parallel motor task. To track the response of the visual system during the task and to determine potential differences in the response of the visual system and in the speed in the simulator and in the real car environment. Methods: The laboratory measurement was realized in a driving simulator OCTAVIA II. The measurement in real conditions was realized in Škoda Octavia as well. The eye-tracking method was used to track the drivers` eyes. Results: In the simulator the more experienced driver managed to do the parallel motor task within a shorter period of time than the less experienced driver, lower frequency of looks at the radio during the tasks with the more experienced driver was not proved. There was not an evidence of more balanced speed during the drive with the more experienced driver in the simulator. On the average the driver spent shorter time doing the tasks in the real environment than in the simulator and the total number of looks at the radio was lower. The speed of the drive in the real environment was lower than the speed in the simulator. Key words:...

Analysis of the machinery as a component of the accident system in the area of traffic operations of self-propelled motor vehicles
SLUKA, Jiří
The theme of this student thesis is {\clq}qAnalysis of the machinery as a component of the accident system in the area of traffic operations of self-propelled motor vehicles``. It deals with problems of traffic and main causes of deaths and injuries in road accidents, and proposes a possibility of their elimination. The solution is based on the fact that most of the road accidents are caused by drivers themselves who don´t pay enough attention by driving or their behaviour behind the wheel isn´t sufficient. The proposed solution is supposed to monitor the traffic in real time and in co-operation with specially-designed program installed in the electronic control unit of the vehicle it´s able to notify the driver of dangers around him. The system is also able to dynamically control the traffic in order to prevent traffic-jams, accidents on pedestrian crossings, etc. As a result of system implementation the author estimates rapid decrease in fatal road accidents, serious injuries and physical damages.
