| Abstract: | So far, road testing and demonstration applications for intelligent and connected vehicles (ICVs) with autonomous driving functions have been widely carried out at home and abroad. The challenges in the safety testing and assessment methods for ICVs have attracted great attention of researchers. Initially this paper focuses on the main safety risks in intellectualization and networking of vehicles, and divides the safety test and assessment process into two stages: the basic assessment and monitoring and adjustments. In the basic assessment stage, the product is comprehensively assessed for compliance with process assurance and testing requirements. In the stage of monitoring and adjustments, the safety assessment results are adjusted timely based on the vehicle condition monitoring. Then the inherent logic, principles and requirements of scenario-based testing, safety assessment and monitoring are described emphatically. Finally the paper elaborates the methods and the main requirements for process assurance, i.e. the functional safety, the safety of the intended functionality, cyber security and data security, and illustrates the test methods including the simulation/virtual testing, track testing, real-world testing, cyber security and data security testing, data storage testing and software update testing. The method proposed in this paper provides a reference for the comprehensive safety assessment of intelligent and connected vehicles with autonomous driving functions under specific operational design conditions. |
