面向服务架构的汽车功能安全开发研究

Research of Automotive Functional Safety Development for Service Oriented Architecture

为实现面向服务架构(SOA)的整车功能安全开发,在分析SOA特点的基础上,结合ISO26262标准,建立基于SOA的汽车功能安全正向开发流程,提出了基于功能的概念开发阶段和基于架构的系统开发阶段的功能安全设计方法:在概念开发阶段,面向产品能力导出功能安全需求,定义产品能力的功能安全等级;在系统开发阶段,基于软件组件架构、物理部署等实现技术安全需求的进一步导出与分配。

In order to realize the development of vehicle functional safety based on Service Oriented Architecture(SOA),the forward development process for automotive functional safety based on SOA is established combining with the ISO 26262 standard.The functional safety design methods of function-based concept phase and architecture-based system development are proposed.On the one hand,for the concept development phase,the functional safety requirements are derived based on the product capabilities,and the function safety class of product capabilities is defined.On the other hand,for the system development phase,the technical safety requirements are derived and distributed based on the software component architecture and physical deployment.
