基于R156法规认证体系的智能网联汽车软件升级管理系统优化

Optimization of Intelligent Connected Vehicle Software Upgrade Manage⁃ment System Based on R156 Regulation Certification System

为保证智能网联汽车的软件升级活动符合R156法规,对R156法规进行解读并提出一种基于R156法规认证体系的软件升级管理系统优化方案。首先,提出一种基于软件升级管理系统远程更新的RX软件识别码(RXSWIN)的建设及实施方案,对RXSWIN的组成方案进行了阐述,识别与法规有关的电子控制单元,软件升级如涉及到认证参数的改变则更新RXSWIN。车辆下线后,中央网关读取软件升级管理系统下发的RXSWIN,将初始值传送给车机进行展示。软件更新管理系统(SUMS)体系建设方面,分析SUMS管理体系文件、SUMS管理流程文件、相关文件存储方案,列出了SUMS体系认证所需文件。最后依据R156法规对车辆型式认证(VTA)的要求对车型产品进行摸底测试评估,对测试项目进行了描述。为汽车企业的软件升级管理建设提供指导方案。

In order to ensure that the software upgrade activities of intelligent networked vehicles comply with the R156 regulations,the R156 regulations are interpreted and an optimization scheme of software upgrade managerment system based on R156 regulation certification system.First ofall,an construction and implementation plan based on the remote update of the software upgrade management system is proposed.The components of RX Software Identification Number(RXSWIN)are described,the electronic control units that are relevant to the regulations are identified,and the software upgrade involving changes to certification parameters should update the RXSWIN.After the vehicles are off the assembly line,the central gateway reads the RXSWIN issued by the software upgrade management system and transmits the initial value to the vehicle for display.In terms of the construction of the software update management system(SUMS),the SUMS management system documents,SUMS management process documents,and related file storage schemes are analyzed,and the documents required for the certification of the SUMS are listed.Finally,according to the requirements of R156 regulations for vehicle type approval(VTA),the model products are thoroughly tested and evaluated,the test items are described.It provides a guidance scheme for the software upgrade management construction for automotive enterprises.
