AUTOSAR架构下软件功能安全研究与应用

Research and Application of Software Functional Safety Under AUTOSAR Architecture

CP AUTOSAR作为整个汽车行业一种标准化的开放式架构,随着汽车行业的发展,在车载软件开发中运用得越来越广泛,同时汽车作为人们出行的重要交通工具,汽车的安全性也越来越重要。为了开发满足ISO 26262的车载软件,文章分析ISO 26262对软件安全的要求,并结合CP AUTOSAR开发规范以及CP AUTOSAR的功能安全机制,对CP AUTOSAR的功能安全机制进行深入研究,同时基于ISO 26262的软件安全要求提出基于AUTOSAR架构进行软件安全机制的应用方案,对当前车载软件功能安全的实施具有重大意义。

CP AUTOSAR as a standardized open architecture of the entire automotive industry,with the development of the automotive industry,more and more widely used in in-vehicle software development,and at the same time,as an important means of transportation for people to travel,the safety of automobiles is becoming more and more important.In order to develop on-board software that meets ISO 26262,this paper analyzes the software safety requirements of ISO 26262,and combines the CP AUTOSAR development specification and the functional safety mechanism of CP AUTOSAR to conduct in-depth research on the functional safety mechanism of CP AUTOSAR,and puts forward an application scheme for software safety mechanism based on AUTOSAR architecture based on ISO 26262 software safety requirements.It is of great significance for the implementation of functional safety of current in-vehicle software.
