Network Optimization Aspects of Autonomous Vehicles: Challenges and Future Directions

Tamás Budai Ernö Horváth Akos Kovacs Miklos Unger Rudolf Krecht Norbert Marko

Publication Name: IEEE Network

Publication Date: 2023-07-01

Volume: 37

Issue: 4

Page Range: 282-288

Description:

Global megatrends, such as urbanization, population growth, and emerging network solutions are accelerating the development of the Connected and Autonomous Vehicles (CAVs) industry. There are many truths, some misconceptions, and even some excitement about CAVs in the public's opinion. The main objective of the current article is to provide a comprehensive review, eliminate misconceptions, and outline the future of the network optimization aspects of autonomous vehicles by presenting various multidisciplinary methods, such as cooperative perception. Given our extensive experience with CAVs, we are aiming to share some of the insights and knowledge we have gained, along with relevant use-cases and experiment results.

Internet of digital reality: Infrastructural background – Part II

Aádám Csapó Tamás Budai György Wersényi P. Baranyi

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2021-01-01

Volume: 18

Issue: 8

Page Range: 91-104

Description:

Internet of Digital Reality (IoD) is a concept that extends the Internet of Things (IoT) with the management, transmission and harmonization of digital realities. IoD covers aspects of connectivity, accessibility and usability with respect to different cognitive entities present in the digital world, via a confluence of technologies including virtual reality, artificial intelligence and 2D digital environments, in a way that recognizes human factors and cognitive aspects as key issues. Devices, interfaces, and interacting entities can be enabled through IoD to share digital realities and to thereby build a new level of reality, using intelligent connections mostly based on immersive virtual scenarios and multi-modal interactions in both public and private networks. In this paper, we look into the infrastructural requirements of and challenges behind the Internet of Digital Reality, which must be solved in order to deliver a high-quality user experience while keeping the increasing complexity of these networks at bay.

Introducing the concept of internet of digital reality – part i

Aádám Csapó Tamás Budai György Wersényi P. Baranyi

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2021-01-01

Volume: 18

Issue: 7

Page Range: 225-240

Description:

With the growing pervasiveness of Virtual Reality, Augmented Reality, Mixed Reality and Digital Twins combined with Artificial Intelligence, 5G networks and the omni-present 2D Web, we are entering into a new era, characterized by a multi-modal entangled combination of previously disparate realms of IT with human and social cognitive systems. This process of entanglement is arguably leading to a new, qualitatively different kind of reality, in which the bor-ders between the physical and digital world, as well as digital representations and simulations thereof are becoming increasingly fuzzy. Based on these developments, the paper re-interprets some well-known concepts – including virtual reality, augmented reality, mixed reality, as well as virtual / digital simulations and virtual / digital twins. Based on these new interpretations, the paper introduces the higher-level structures of Digital Reality (DR) and Internet of Digital Reality (IoD). It is argued that these structures can lead to a better understanding of the new possibilities afforded to humanity by pervasive digital technologies.

Linear state space modeling and control teaching in maxwhere virtual laboratory

Miklós Kuczmann Tamás Budai

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2019-01-01

Volume: 16

Issue: 6

Page Range: 27-39

Description:

It is widely known that virtual laboratories can improve and complete university lectures. This paper presents laboratories, that allow engineering students to design a pole placement based controller for typical control problems: inverted pendulum, Furuta pendulum, crane, ball and beam. The dynamics of the plants and instructions for controller design and test are provided on smartboards of the virtual laboratory. The controller can be designed by the help of Octave Online. Finally, the controller performance can be studied by the model of the real-life application. The mathematical models and controller design are presented as well as the experiences in the virtual laboratory of control engineering.

Development of a VR capable virtual laboratory framework

Miklós Kuczmann Tamás Budai

Publication Name: Pollack Periodica

Publication Date: 2018-12-01

Volume: 13

Issue: 3

Page Range: 83-93

Description:

The aim of this paper is to introduce the design steps and implementation details of a system, which combines modern web-technologies and open-source simulation software to create a virtual laboratory framework. In order to validate the functionality of this framework and to demonstrate its capabilities, a classic experiment from the field of control theory was implemented; the inverted pendulum. In this experiment, a simulated controller keeps the rod of the pendulum in an upright position. Users can change different parameters of the model and then test the impact of these changes in a very intuitive and interactive way, by applying force to the pendulum model in 3D and observing the behavior of the controller.

Description:

In the frame of the project TÁMOP 4.2.2.A, at the Széchenyi István University, the goal is to work out a new finite element package for the simulation and optimization of permanent magnet synchronous motors. These motors are then used to drive new electric cars. The aim of the two dimensional package is the fast numerical modeling of these electric devices by the use of free tools presented in the paper. Of course, the software is aimed to use it in the simulation of other devices, and three dimensional problems, as well.
