Investigation of the Radar Cross-Section and its Optimization Potential for ADAS Tests

Leticia Pekk Robert Magai Norbert Simon Balazs Molnar

Publication Name: Engineering Technology and Applied Science Research

Publication Date: 2025-02-01

Volume: 15

Issue: 1

Page Range: 20493-20499

Description:

The objective of this study is to examine the Radar Cross Section (RCS) of instruments designed for Autonomous Driving Systems (ADAS) testing, with the intention of comparing the results to those of actual human subjects. The RCS values of both dummy and platform objects were documented at varying distances and positions, with the objective of ascertaining the extent to which dummies can serve as substitutes for human values in vehicle radar sensing tests. The findings, substantiated by graphical representations and statistical analyses (e.g., Pearson and Spearman correlation), reveal a moderately strong positive correlation between the RCS and human values, which is statistically significant. The outcomes of the tests demonstrate that the developed instruments can substitute for real human radar cross-section values within the range of 5-15 m. However, as the distance increases, larger deviations are observed. These discrepancies underscore the necessity for a refinement of the dummy design in future ADAS tests, ensuring that distance-sensitive tests accurately reflect real human measurements.

The development and application of a global positioning system – based monitoring system for soil stabilization vehicles

András Háry Balázs Baráth Norbert Simon

Publication Name: Journal of Ecological Engineering

Publication Date: 2025-01-01

Volume: 26

Issue: 3

Page Range: 1-7

Description:

The accuracy and efficiency of soil stabilization works are key to ensuring the durability of roads. During the conducted research, a GPS-based (global positioning system) tracking system was developed that can monitor the movement of soil stabilization vehicles in real time, recording the exact location and working width of the stabilized road sections. The system’s software solutions enable the conversion of location coordinates from the WGS84 (World Geodetic System) system to EOV (EOV as Uniform National Projection system) format and visualization of the results in AutoCAD. The developed tool can significantly contribute to the improvement of the quality control of soil stabilization works, as the development of road defects resulting from stabilization errors can be reduced with the help of documentation and visualization. During the testing of this system, the development proved to be successful and provides an opportunity to perform soil stabilization processes more efficiently and reliably, thereby improving the service life of road surfaces and traffic safety.

Comparative Analysis of Electric Vehicle Energy Consumption in Urban and Highway Environments Using CAN-Based Data Collection

Richárd Peszleg Norbert Simon

Publication Name: Engineering Perspective

Publication Date: 2025-12-28

Volume: 5

Issue: 1 Special Issue

Page Range: 8-13

Description:

This study presents a comparative analysis of the energy consumption characteristics of Volkswagen Golf equipped with an electric powertrain in urban and interurban (highway) driving environments. The primary objective of the research is to determine which traffic context offers more favorable operating conditions in terms of energy efficiency for this vehicle category. Special emphasis is placed on the role of regenerative braking, particularly in urban traffic characterized by frequent acceleration and deceleration cycles, which may significantly influence the vehicle’s specific energy consumption through energy recovery mechanisms. The measurement data were recorded under real-world traffic conditions along two representative routes: a highway section between Zalaegerszeg and Keszthely, and the urban road network within Zalaegerszeg. During data collection, vehicle parameters extracted from the CAN network—including brake pressure, speed, accelerator pedal position, drivetrain power, battery voltage and current, state of charge, as well as longitudinal and lateral acceleration—were recorded using a custom program developed in Simulink and a Kvaser CAN logger device. The goal of the analysis is to compare the energy efficiency indicators of the two driving profiles and to draw conclusions, based on the recorded data, about the real-world efficiency of electric vehicle operation in urban settings. The findings may contribute to the optimization of operational strategies for electric vehicles and serve as a foundation for future large-scale investigations.

Comparative Study of BASF Ultrafuse 316L and Markforged 17-4PH Stainless Steel Filaments Processed by Fused Filament Fabrication

Eszter Kókai Norbert Simon

Publication Name: International Journal of Automotive Science and Technology

Publication Date: 2025-12-17

Volume: 9

Issue: 1st Future of Vehicles Conf.

Page Range: 77-81

Description:

Metal additive manufacturing is receiving increased attention today, as major industries such as the automotive, aerospace, and medical sectors place a stronger emphasis on it. Among the numerous technologies, fused filament fabrication (FFF) is gaining more focus due to its relatively low equipment cost and ease of application. The production of a solid metal part begins with the extrusion of a metal powder-filled filament, followed by printing, debinding, and heat treatment, through which the final strength is achieved. Among the commercially available filaments, stainless steel–based composites are the most widespread, as they offer good printability, corrosion resistance, and mechanical stability. The two most used materials in this category are BASF Ultrafuse 316L and Markforged 17-4PH alloys. These two materials lend themselves well to comparison, as they are designed for the same manufacturing technology but exhibit different metallurgical behaviors and process requirements, thus providing a comprehensive view of the capabilities and limitations of metal FFF technology. In this study, we aim to demonstrate how these two materials differ in their processing requirements, microstructural evolution, and resulting mechanical performance, and to show what can be achieved when manufacturing metal composites using FFF technology. The main differences between the two filaments are presented in a comparative table to provide a clear and structured overview of their distinct characteristics.
