自动驾驶系统软件的功能安全认证标准及实践

The Functional Safety Certification Standard and Application on Software in Autonomous Driving System

在目前“软件定义汽车”的思想指导下,自动驾驶系统软件的质量对整体系统的功能表现影响巨大,实施软件功能安全认证是确保其开发质量的必要工作内容。本文在概要介绍自动驾驶技术的发展现状与趋势的基础上,阐述了作为认证依据的ISO 26262《道路车辆功能安全》中的主要内容,对联合应用该标准中的功能安全管理、软件产品开发和支持流程等开展自动驾驶系统软件模块认证的流程进行了系统梳理与分析。最后以自动驾驶系统中多传感器数据融合软件模块的功能安全认证为例,阐述流程与方法的应用过程。本文工作对于实施自动驾驶系统软件的功能安全认证具有参考与借鉴作用。

Under the guidance of the current thought of"software-defined vehicle",the quality of autonomous driving system software has a huge impact on the functional performance of the overall system.The implementation of software functional safety certification is a necessary work to ensure the quality of its development.On the basis of an overview of the development status and trend of automatic driving technology,this paper expounds the main contents of ISO 26262"Road Vehicle Functional Safety"as the certification basis,applies the functional safety management,software product development and support processes in the standard to systemically sort out and analyze the process of developing autonomous drivin system software module certification.Finally,taking the function safety certification of the multi-sensor data fusion software module in the autonomous driving system as an example,the application process of the processes and methods are described.The work of this paper has reference value for the implementation of functional safety certification of autonomous driving system software.
