Abstract

This study aims to provide a detailed evaluation and comparison of the performance of forward collision warning (FCW) and automatic emergency braking (AEB) systems in lane-changing scenarios, focusing on their detection range and detection angles. Real-world tests were conducted with a Tesla Model 3 and a KIA K8 to assess their detection capabilities. The experiments simulated common highway lane-changing scenarios, referencing Euro NCAP standards. Testing environments included a full-size target robot and a guided vehicle target to ensure accuracy. Preliminary tests established the test speed range and relative distances, while main tests focused on three key variables: time-to-collision (TTC) for FCW activation, TTC for AEB activation, and relative lateral positions of the target and test vehicles. The study also analyzed collisions despite FCW and AEB activation, identifying system limitations by examining deviations in TTC values and their correlation with collisions. These findings provide insights into the effectiveness and reliability of FCW and AEB systems under various conditions, aiding the advancement of ADAS technologies.

用于评估 AEB 和 FCW 功能的高速公路切入场景试验台和分析

本研究旨在对前撞预警（FCW）和自动紧急制动（AEB）系统在变道场景中的性能进行详细评估和比较，重点关注其探测范围和探测角度。我们使用特斯拉 Model 3 和起亚 K8 进行了实际测试，以评估它们的检测能力。实验参照欧洲 NCAP 标准，模拟了常见的高速公路变道场景。测试环境包括一个全尺寸目标机器人和一个制导车辆目标，以确保准确性。初步测试确定了测试速度范围和相对距离，而主要测试则集中在三个关键变量上：启动 FCW 的碰撞时间 (TTC)、启动 AEB 的碰撞时间 (TTC) 以及目标和测试车辆的相对横向位置。研究还分析了在 FCW 和 AEB 启动的情况下发生的碰撞，通过检查 TTC 值的偏差及其与碰撞的相关性，确定了系统的局限性。这些发现有助于深入了解 FCW 和 AEB 系统在各种条件下的有效性和可靠性，从而推动 ADAS 技术的发展。

期刊介绍： The International Journal of Automotive Technology has as its objective the publication and dissemination of original research in all fields of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING. It fosters thus the exchange of ideas among researchers in different parts of the world and also among researchers who emphasize different aspects of the foundations and applications of the field. Standing as it does at the cross-roads of Physics, Chemistry, Mechanics, Engineering Design and Materials Sciences, AUTOMOTIVE TECHNOLOGY is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from thermal engineering, flow analysis, structural analysis, modal analysis, control, vehicular electronics, mechatronis, electro-mechanical engineering, optimum design methods, ITS, and recycling. Interest extends from the basic science to technology applications with analytical, experimental and numerical studies. The emphasis is placed on contributions that appear to be of permanent interest to research workers and engineers in the field. If furthering knowledge in the area of principal concern of the Journal, papers of primary interest to the innovative disciplines of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING may be published. Papers that are merely illustrations of established principles and procedures, even though possibly containing new numerical or experimental data, will generally not be published. When outstanding advances are made in existing areas or when new areas have been developed to a definitive stage, special review articles will be considered by the editors. No length limitations for contributions are set, but only concisely written papers are published. Brief articles are considered on the basis of technical merit.
