Description

technical field [0001] The invention belongs to the technical field of vehicle Ethernet, and in particular relates to an Ethernet gateway and a vehicle with a configurable port mode. Background technique [0002] With the increasing complexity of the electrical system of new energy vehicles and the increasing amount of data interaction between controllers, vehicle Ethernet gateways are gradually being used in new energy vehicles. However, limited by the different electronic and electrical architectures of different vehicle models, the controllers connected to the Ethernet gateway interface will also be different. The vehicle Ethernet is different from the traditional Ethernet. The master-slave mode of both communication parties must be set before the communication of the vehicle Ethernet. In order to make an Ethernet gateway product compatible with different vehicle electrical and electronic architecture platforms, and at the same time realize the first layer of hardware ne...
