The invention provides a method and a system for realizing high-voltage OTA (Over-the-Air) upgrading of whole-vehicle-level software of a new energy automobile, and the method comprises the following steps: when an Internet of Vehicles module receives whole-vehicle-level software updating OTA task information issued by a cloud end, a central control module receives the whole-vehicle-level software updating OTA task information sent by the Internet of Vehicles module; after judging that the high-voltage battery module and the high-voltage-to-low-voltage module are in an operable state, triggering the high-voltage battery module to perform high-voltage action; and the high voltage output by the upper high-voltage action is transmitted to the high-voltage-to-low-voltage module to be converted into low voltage, and then the low voltage is transmitted to other modules of the whole vehicle, so that the high-voltage OTA of the whole-vehicle-level software of the new energy vehicle is upgraded. The problem that in the prior art, limited energy provided by a low-voltage storage battery of a whole vehicle cannot meet power consumption needed by OTA upgrading, and the duration upper limit of an OTA upgrading task is limited can be solved.

    本申请提出一种实现新能源汽车整车级软件高压OTA升级的方法及系统,该方法包括:当车联网模块接收到云端下发的整车级软件更新OTA任务信息时,中央控制模块接收来自车联网模块发送的整车级软件更新OTA任务信息;判断高压电池模块和高压转低压模块为可运行状态后,触发高压电池模块进行上高压动作;将上高压动作输出的高电压传输给高压转低压模块转换成低电压,再将低电压传输给整车其他模块,以使新能源汽车整车级软件高压OTA进行升级。本申请能够解决现有技术中整车低压蓄电池提供的有限能量不能满足于OTA升级所需的电耗,使得OTA升级任务的时长上限有所限制的问题。
