Embodiment 1
[0020] as attached figure 1 As shown, the automotive electrical system based on optical fiber network described in this embodiment adopts a bus structure, with a single backbone optical fiber as the backbone network, all sensors are shared through the backbone network, and each ECU is connected to the backbone network through a gateway. The system framework of the optical fiber network described in the present invention draws lessons from the design concept of GMLAN, a general company of the United States, and uses the specified architecture (OSI) for open system interconnection as a model to establish a high-speed and effective communication framework. According to the characteristics of automotive communication, the physical layer, data link layer, network layer, transport layer, and application layer are mainly introduced; the automotive electrical system based on optical fiber network developed based on this model can fully meet the needs of vehicle electrical systems now a...
