description	The invention discloses an OTA upgrading method capable of reducing energy consumption, and belongs to the technical field of vehicles. After the vehicle-mounted terminal receives the upgrading file sent by the OTA cloud end, in the downloading stage, only the central domain controller and the remote communication terminal are controlled to be kept in the awakening state, and then downloading of the upgrading package can be achieved. Compared with an existing scheme that all controllers of the whole vehicle need to be controlled to wake up in the downloading stage, the method has the advantages that related systems participating in the downloading task are controlled to wake up, systems not participating in the downloading task are not awakened, and energy consumption in the downloading process can be reduced. And in the upgrading stage, the electronic controller to be upgraded and the upgrading associated system are controlled to be kept in an awakening state, so that corresponding upgrading is realized.
