The application discloses a vehicle section wake-up method based on a network protocol, and is applied to a distributed network communication system comprising a gateway and multiple sub-network sections. In view of the problem that the existing whole-vehicle unified wake-up mechanism leads to excessively high static energy consumption and lacks scene perception, the method determines a function scene according to a local wake-up source by a wake-up trigger node, sets corresponding scene flag bits in a network management message, performs arbitration analysis on the scene flag bits in combination with a bottom-layer hardware wake-up signal by a gateway controller, and performs directional forwarding of the message to a matched target network section. A maintaining wake-up controller of the target network section continuously sends the message to maintain a network wake-up state during function execution. After the scene function is finished, each node actively stops sending the message, and the gateway releases the network after a timeout, so that the target network section is cooperatively put into sleep. The application can selectively wake up relevant network sections according to scenes, and significantly reduces vehicle static energy consumption.
