Testbed and Analysis of Highway Cut-In Scenarios for Evaluating the AEB and FCW Functions

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.
