Abstract

Despite the popularization of Adaptive Cruise Control (ACC), accidents caused by system limitations persist in real-world driving. This study systematically evaluates the dynamic performance and limits of ACC, aiming to secure fundamental data for future accident reconstruction and forensic analysis of Advanced Driver Assistance System (ADAS)-equipped vehicles. Real-vehicle experiments were conducted on two commercially available Korean ACC vehicles, utilizing EuroNCAP standard scenarios Car-to-Car Rear Stationary (CCRs), Car-to-Car Rear Moving (CCRm) and accident-reflective edge cases (Overlap, Angle). Results showed the maximum collision avoidance speed for a stationary target (CCRs) was 80 km/h, and the limit relative speed for a moving target (CCRm) was approximately 95 ~ 100 km/h. Crucially, collision risk increased sharply due to delayed detection or detection failure in edge cases like partially occupying the lane (Overlap) or skewed (Angle) targets. We suggest that these findings serve as crucial evidence for determining ACC operational limits based on the target’s dynamic and geometric state during accident investigation.
