The invention discloses a vehicle upgrading method, a controller and a vehicle, and the vehicle upgrading method is applied to a high-voltage module in the vehicle, and comprises the following steps: during the upgrading process of the high-voltage module, when the current voltage of a storage battery of the vehicle is less than or equal to a first preset voltage, interrupting the upgrading of the high-voltage module, generating an interruption mark and storing the transmitted upgrading data; when the current voltage of the storage battery is greater than or equal to a second preset voltage, upgrading the high-voltage module according to the interruption mark and the transmitted upgrading data; according to the vehicle upgrading method, the size of a software package does not need to be considered, the success rate of upgrading of the high-voltage module can be increased, the problem of power shortage of the whole vehicle can be avoided, and the OTA upgrading requirement of the whole vehicle is met.

    本发明公开了一种车辆升级方法、控制器和车辆,车辆升级方法,应用于车辆中的高压模块,包括:在高压模块升级过程中,当车辆的蓄电池的当前电压小于或等于第一预设电压时,中断对高压模块的升级,生成中断标记并保存已传输的升级数据;当蓄电池的当前电压大于或等于第二预设电压时,根据中断标记和所述已传输的升级数据对高压模块进行升级;其中,第二预设电压大于第一预设电压本申请的车辆升级方法不用考虑软件包的大小,能够提高高压模块升级的成功率,且能够避免出现整车亏电的问题,满足整车的OTA升级需求。
