Abstract

The embodiment of the invention provides a network topology determination method and device, a vehicle network topology structure and a vehicle, and the method comprises the steps: determining a network platform corresponding to each electric control system according to the target cost of the whole vehicle and a function list of the whole vehicle; clipping the network platform corresponding to each electronic control system to obtain a sub-network topology corresponding to each electronic control system; and combining the sub-network topologies corresponding to the electronic control systems to determine a network topology. According to the technical scheme, a large number of workloads and expenses of electronic control system development are concentrated in the two gateways, the two central gateways cooperate to complete unified work of network specifications and communication protocols, autonomous development can be conducted by suppliers, the development period can be greatly shortened, and the development cost can be greatly reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile gateways, and in particular to a method and device for determining network topology, a vehicle network topology structure, and a vehicle. Background technique [0002] With the continuous upgrading of automobile networking and intelligence, the speed of network topology update and iteration of vehicle electronics is gradually increasing, and network communication specifications and application layer communication protocols are inevitably updated during the iterative process. [0003] In the development of complete vehicle electronics and electronics, especially in the process of integrating network architectures of different platforms, it often happens that the network communication specifications or application layer communication protocols used by the various electronic control systems selected for the transition project are different. The existing general strategy is to...
