The vehicle-mounted software updating method comprises the following steps: after software updating is started, acquiring a voltage measurement value of a vehicle-mounted power supply; if the voltage measurement value is equal to or less than a second threshold value, a progress rate in the software update is obtained. And when the progress rate is less than a set value, interrupting the software update. When the progress rate is equal to or greater than the set value, an operation mode of the regional control unit is switched to a power saving mode, and a second predicted voltage value of the in-vehicle power supply at a time when the update is completed is calculated. And continuing the software updating under the condition that the second predicted voltage value is greater than a first threshold value.
一种车载软件更新方法,包括:在开始软件更新后,获取车载电源的电压测量值;在所述电压测量值等于或小于第二阈值的情况下,获取所述软件更新中的进展率。在所述进展率小于设定值的情况下中断所述软件更新。在所述进展率等于或大于所述设定值的情况下将所述区域控制单元的操作模式切换为省电模式,并且计算所述车载电源在所述更新完成时刻的第二预测电压值。在所述第二预测电压值大于第一阈值的情况下继续所述软件更新。
