Abstract:

Safety of the Intended Functionality (SOTIF) is a vital part of autonomous driving and poses a significant challenge for intelligent connected vehicles, which requires comprehensive and high-efficiency testing and verification methodology to effectively assist the safety development process of the system. Based on critical scenarios, this paper proposes a dual-loop framework with close loop verification and dynamic evaluation, summarizes the technologies for critical scenarios construction, and further formulizes a quantitative method for acceptance criterion. Finally, this article looks forward to key researches in the area of SOTIF testing and verification. The paper aims to provide a maneuverable and theoretical reference for the engineering practice on the SOTIF for intelligent connected vehicle.
