The Development and Trend of Vehicle Functional Safety

In the development stage of vehicle applications, ensuring the safety of the vehicle is always a key condition. However, the current automotive functional safety design is challenged by a variety of factors, such as the complexity of the new generation of automotive electrical and electronic (E/E) architecture, the continuous update of the automotive functional safety standard ISO26262, and the new AUTOSAR adaptive platform standard. The release of different types of cost increases. This paper summarizes the latest developments of vehicle functional safety design methods through analysis, design, optimization and operation stages: 1) functional safety analysis; 2) functional safety assurance; 3) safety perception cost optimization; 4) safety-critical multi-functional dispatch. It then provides the future trend of functional safety design methods, which will be directly oriented to automatic vehicles.
