The invention provides a vehicle remote upgrading method and system, and relates to the field of remote upgrade.The method is applied to a T-BOX vehicle-mounted terminal and comprises the steps that version information of an ECU to be upgraded is obtained and uploaded to an OTA platform so as to instruct the OTA platform to issue an upgrading package file of the ECU to be upgraded and a current version program file to the T-BOX vehicle-mounted terminal according to the version information; receiving an upgrade package file and a current version program file, storing the upgrade package file based on the first storage partition, and storing the current version program file based on the second storage partition; issuing the upgrade package file stored in the first storage partition to the ECU to be upgraded for remote upgrade; and if the remote upgrading fails, issuing the current version program file of the to-be-upgraded ECU stored in the second storage partition to the to-be-upgraded ECU for rollback. The ECU does not need to have extra storage space, the memory requirement of the ECU is reduced, and hardware resources are saved.
本发明提供一种车辆远程升级方法及系统,涉及远程升级领域,该方法应用于T‑BOX车载终端,包括:获取待升级ECU的版本信息并上传至OTA平台,以指示OTA平台根据版本信息下发待升级ECU的升级包文件和当前版本程序文件至T‑BOX车载终端;接收升级包文件和当前版本程序文件,并基于第一存储分区存储升级包文件,基于第二存储分区存储当前版本程序文件;将第一存储分区存储的升级包文件下发至待升级ECU进行远程升级;若远程升级失败,将第二存储分区存储的待升级ECU的当前版本程序文件下发至待升级ECU进行回滚。本发明无需ECU有额外的存储空间,降低了ECU的内存需求,节省硬件资源。
