Centralized automotive electronic and electrical architecture building method, topological structure and storage medium

The invention provides a centralized automotive electronic and electrical architecture construction method, a topological structure and a storage medium. The method comprises the following steps: dividing a whole vehicle area into a plurality of sub-areas; an I/O gateway is installed in each sub-region, and each electronic control unit in the sub-region is in communication connection with the I/O gateway in the sub-region through a CAN line; and each I/O gateway is in communication connection with the vehicle-mounted central gateway through a vehicle-mounted Ethernet. According to the centralized automotive electronic and electrical architecture building method, the topological structure of the automotive electronic and electrical architecture is simplified, the number of terminal sensors is optimized, the weight of wire harnesses is reduced, energy consumption is reduced, cost is saved, the vehicle-mounted Ethernet is adopted in a whole vehicle backbone network, and service-oriented SOME/IP communication can be achieved.
