摘要
软件定义汽车是近年来汽车电子化的发展趋势之一,软件的迭代开发在车辆的开发中扮演越来越重要的角色,而且相对于传统的设变更频繁、更快速。为适应该趋势需要建立控制器软件类数据的管理规范,搭建软件类数据的管理平台,从而将软件类数据纳入到研发、制造、质量返修、售后所有汽车产品生命周期的管理中。本文介绍了控制器软件类数据管理系统的要点。该系统涉及到软件零部件化的理念、软件版本的定义、软件类数据分类与EBOM搭建、软件的产线灌装与售后升级的逻辑。通过软件接口打通了研发数据(EBOM)与制造管理系统、售后诊断仪系、OTA系统之间的对接。在多款车型上的应用表明,该系统满足了对软件唯一性的识别,实现了软件类数据与整车制造数据流的结合,并得到生产线的在线软件灌装和售后的在线升级等规模化的一体化应用,为控制器的软件开发独立化、快速迭代以及业务的数字化转型创造了系统化的平台基础。
In recent years,software-Defined-Vehicle(SDV)is one of new trends for vehicle E&E development.SW development with iteration become more and more important,faster and more frequent than the traditional design change in vehicle development.In order to implement this trend,it is necessary to define the SW data management rule,build SW data management platform,and then all SW data is to be bring into the vehicle life-cycle management which includes design,manufacturing,quality repair and aftersales.The paper introduces the main points of the SW data management systems development for passenger vehicles.The system development involves the concept of considering SW as part,SW version definition,SW data classification and its BOM construction,the logic determination for the SW writing on the OEM assembly line and updating in the aftersales dealers.The R&D data(EBOM)is got through with the manufacturing management system,the aftersales diagnostic terminals and OTA system by SW interfaces.The systematic appliance in passenger vehicles presents the independent design meets the uniqueness of SW data recognition,the flow combination of SW data and vehicle manufacturing information.The scaled use of SW data on-line writing in the OEM assembly line and the SW data refresh in the dealers is implemented successfully.It is the base for independent SW development and quick iteration as well as the digital transformation of business.
