Recent Advances and Future Trends for Automotive Functional Safety Design Methodologies

Guaranteeing safety is always a prerequisite in the process of realizing various automotive applications. However, the automotive functional safety design has been challenged by multiple factors, such as the complexity of the new generation automotive electrical and electronic (E/E) architecture, the continuous release and update of automotive functional safety standard International Standardization Organization (ISO) 26262, the release of new AUTOSAR adaptive platform standard, and the increase in different types of costs. In this article, we summarize the recent advances of automotive functional safety design methodologies through analysis, design, optimization, and runtime phases, respectively: 1) functional safety analysis; 2) functional safety guarantee; 3) safety-aware cost optimization; and 4) safety-critical multifunctional scheduling. Then, we provide the future trends in functional safety design methodologies that will be directly oriented to autonomous vehicles and adapt to the next generation functional safety standard ISO 21448.
