The invention discloses a remote upgrading method which can solve the problem that in the prior art, upgrading time is long when a vehicle is remotely upgraded, and therefore user experience is improved. The remote upgrading method comprises the steps that a master control node receives a plurality of installation packages from a server and configuration files corresponding to the installation packages; the master control node sends each installation package in the plurality of installation packages to the corresponding target sub-node based on the corresponding relationship between the installation packages and the target sub-nodes; the main control node obtains the actual electric quantity of the storage battery, and compares the actual electric quantity with the total electric quantity required by the multiple target sub-nodes for executing the corresponding installation package flashing task; and if the master control node determines that the actual electric quantity of the storage battery is not less than the total electric quantity consumed by the plurality of target sub-nodes to execute the corresponding installation package brushing, the plurality of target sub-nodes are controlled to execute the brushing task of the corresponding installation package based on a preset control strategy, and the plurality of target sub-nodes are controlled to be restarted after a preset duration to complete the upgrading process.
本申请公开了一种远程升级方法,能够解决现有技术中车辆远程升级时升级时间较长的问题,从而提升用户体验。远程升级方法包括:主控节点接收来自服务器的多个安装包以及每个安装包对应的配置文件;主控节点基于安装包与目标子节点的对应关系将多个安装包中的每个安装包发送给对应的目标子节点;主控节点获取蓄电池的实际电量,并与多个目标子节点执行对应安装包刷写任务所需的总电量进行比较;若主控节点确定蓄电池的实际电量不小于多个目标子节点执行对应安装包刷写所消耗的总电量,则基于预设控制策略控制多个目标子节点执行对应安装包的刷写任务,并在间隔预设时长后控制所述多个子目标节点重启,以完成升级过程。
