摘　　要：为了减少互联互通车载控制器(VOBC)在线软件的计算量,提升VOBC在线软件的运行效率,采用自动生成离线数据方法,对互联互通VOBC离线数据进行分类,按照互联互通车载电子地图规范解析和加工车载电子地图数据;利用XML离线功能配置方法,互联互通VOBC在线软件只需修改配置文件,即可满足多项目定制化差异需求;结合VCP编码思想,将互联互通VOBC离线数据进行VCP编码,以满足SIL4等级的安全要求。本文提出的自动生成VOBC离线数据的方法,提升了离线数据的制作效率,增加了VOBC在线软件的灵活性。To reduce the amount of computation by the online software in the interoperable Vehicle On-Board Controller(VOBC)and to improve the operating efficiency of the VOBC's online softw are,a method of automatically generating offline data is adopted to parse and process the electronic map data according to the specifications of the interoperable on-board electronic map.Using XML offline function configuration method,the different requirements of several projects could be catered only by modifying the configuration file.Combined with the concept of VCP coding,the interoperable VOBCs offline data is encoded in VCP to comply with the specifications of SIL4.This Automatic generation method of the VOBCs off-line data can improve the efficiency of offline data preparation and increase the flexibility of the VOBCs online software.
