Abstract: With the popularization of intelligent driving vehicles, accidents caused by inherent system defects or improper driver operation increase year by year. Based on the systematic engineering of functional safety assurance for intelligent driving, this paper establishes an intelligent driving system safety assurance system covering seven core dimensions, including hardware foundation, software development, regulations and standards, test verification, operation iteration, driver state monitoring and safety awareness improvement. It constructs a full-life cycle protection framework covering human, vehicle and intelligent driving functions, and forms a safety coordination mechanism of human-machine co-driving and shared responsibility. This study builds an integrated governance framework for intelligent driving systems throughout design, verification, operation and application, and provides a systematic solution for the safe and stable development of the industry.
