Zusammenfassung:A power distribution box (PDB) includes relays to connect a vehicle battery to corresponding electronic control units (ECUs) of a vehicle. A processor is programmed to instruct the PDB via a control interface to cause one of the relays to power a target ECU, send a sleep command over a vehicle bus to cause powered ECUs other than the target ECU to sleep, and install a software update to the targetECU. 本公开提供了"擦除-替换OTA智能电力策略"。一种配电箱(PDB)包括将车辆电池连接到车辆的相应电子控制单元(ECU)的继电器。一种处理器，所述处理器被编程来经由控制接口命令所述PDB以致使所述继电器中的一个为目标ECU供电，通过车辆总线发送休眠命令以致使所述目标ECU之外的电动ECU休眠，以及将软件更新安装到所述目标ECU。
