Research on the Application of Functional Safety and STPA in LKA System
Pages 1299 - 1305
Abstract
In order to realize the functional safety and STPA development of the lane keeping assistance system, the road vehicle safety standard ISO 26262 and STPA method is used as the development criterion, and the requirements development of the lane keeping assistance system (LKAs) of the vehicle is analyzed. The work content and requirements of the functional safety concept phase are described, including item definition, hazard analysis and risk assessment, and functional safety concept. The design method and analysis process are analyzed in detail by taking the lane keeping assistance system as an example, and the safety goal and ASIL level are determined. Meanwhile, the corresponding ASIL level assign to the system architecture elements and get the corresponding functional safety requirements. At the same time, the work content of STPA analysis method is described, including define system hazards, determine system-level constraints and safety requirements. establish system safety control structure; identify unsafe control actions and analyze causes; determine safety constraints to obtain safety requirements. It provides some guidance for the design and analysis of safety requirements of other systems in intelligent driving vehicles.
