Design of control unit for an autonomous vehicle
Vobruba, Martin ; Formánek, Martin (referee) ; Adámek, Roman (advisor)
The topic of this bachelor thesis is designing control unit for an autonomous vehicle. The new ECU replaces the old one which was without access to the source code, so its functionality couldn’t be modified. The purpose of the ECU is to receive a message from the control computer, process it, control the actuators according to the orders and inform the computer about their current state. The first part of the thesis is research of the vehicle kinematics and CAN bus. The practical part focuses on the analysis of the previous ECU which is crucial to its replacement. It is followed by the firmware and hardware design. The last practical part of the thesis is the testing of the new ECU’s functionality.

Secure Autonomous Transportation with Remote Control
Prachař, Daniel ; Dobiáš, Patrik (referee) ; Malina, Lukáš (advisor)
This bachelor thesis study the emerging trend of Autonomous Vehicle, which has become one of the most discussed topics in the modern field of transportation and technology. Autonomous Vehicle has great benefits using this technology such as avoiding road hazards and traffic conditions however, with these advances, new challenges come and risks especially in the area of cyber security. The theoretical part of this thesis focuses on introducing autonomous vehicles with their operations. Also, the identification of the communication and analysis of the security problems associated with the vehicles. One of the main security risks is the vulnerabilities of these vehicles to cyber attacks, which can threaten the safety of passengers as well as other road users. The main objective of this work is to propose a suitable solution for securing remote driving and to perform a performance evaluation. The features of such solution shall guarantee low communication delay and overall security. Practical part of the thesis presents two protocols that implement this solution in the application. These protocols are then tested and performance evaluation is performed by measuring the delay between several aspects of the communication. The result of the work is an evaluation of the proposed protocols with their recommendation for practical use.

Návrh autonomního vozidla
BAŠTÝŘ, Jan
The first part of the thesis deals with vehicle autonomy, its application, the levels of automation and then the problem. In the second part, the thesis focuses on artificial intelligence. A substantial part is devoted to Asimov's Laws of Robotics, as the founder of robotics. The practical part deals with the creation of a custom model of an autonomous vehicle, which is modelled in CAD software, printed out using a 3D printer and then assembled and set in motion for use in Agriculture 4.0. It is expected that this vehicle will be used, for example, in a greenhouse where it will collect the necessary data and can be modified if further needs arise.

Virtual testing of autonomous vehicles
Matušková, Lucie ; Fojtášek, Jan (referee) ; Porteš, Petr (advisor)
This bachelor thesis deals with virtual testing of autonomous vehicles. The theoretical part describes an autonomous vehicle, the issue of testing autonomous vehicles. Furthermore, the work is focused on the description of ADAMS Car software and Virtual test drive. The virtual test drive is described for the most part, because it also contains a practical part of the work, which is working with the software.

Computational Model of Control and Behaviour of Self-Driven Vehicle
Kužela, Michal ; Bidlo, Michal (referee) ; Strnadel, Josef (advisor)
This thesis explains basic principles of autonomous vehicles. Based on these principles, it describes proposed simulation model of autonomous vehicle with its behavior in different outer conditions. The model is composed from sensors and vehicle itself. Sensors use an algorithm based on line intersection to detect collisions. Vehicle model is mostly described by physical formulas and custom decision algorithms. Its surrounding objects have parameters that are randomly selected for each simulation run. This thesis also explains implementation of the simulation model with its own simulation framework and an analysis tool for collected data. All of these features are implemented in JavaScript with use of Node.js and an Electron framework.

System for Autonomous Navigation of Toy Car on a Race Track
Steingart, Viktor ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis deals with the design and implementation of a self-driving model race car that is intended to participate at NXP Cup race. First of all, the attention is given to the selection of a suitable platform, which will be used for the implementation of a motion control algorithm that enables autonomous navigation of the autonomous model race car along a specified track. Then, the details of motion control algorithm design and its implementation aspects are explained. Also, the design of an obstacle detection system is presented. Finally, the work is concluded with presentation of various experiments with the implemented self-driving control algorithm and its evaluation.
