Abstract: In response to the high proportion of traffic accidents caused by lane departure and the industry pain point of the lack of standardized and systematic verification methods for the safety performance of intelligent vehicle emergency lane keeping (ELK) system in complex practical scenarios, this study aims to establish a standardized testing process and a scientific robustness evaluation system for ELK system based on the Euro NCAP 2026 version of the Crash Avoidance– Lane Departure Collisions (v1.1), in order to improve the consistency and effectiveness of ELK system testing. The research focuses on the core scenario of overtaking and lane changing collision avoidance between ELK adjacent lane vehicles and motorcycles. The experimental conditions, vehicle preparation, measurement accuracy requirements, and experimental implementation process under this scenario are systematically sorted out; The focus is on analyzing the criteria for dividing robustness levels in the regulations, clarifying core robustness evaluation indicators such as collision position offset and initial position deviation; And a real vehicle verification test is conducted on a pure electric sedan equipped with ELK system, completing the testing and data validity analysis of standard and robustness scenarios. The research results indicate that the ELK system testing method and robustness evaluation system constructed have strong practical feasibility and engineering application value, which can provide theoretical support and practical reference for the development, testing, and optimization of intelligent vehicle ELK system.
