Ethernet gateway and vehicle with configurable port mode

Abstract

The invention discloses an Ethernet gateway and a vehicle with a configurable port mode, comprising a main control unit, an Ethernet switch circuit, an external storage and a power supply circuit; the main control unit has an Ethernet MII interface, an SMI interface and a GPIO interface; the Ethernet The switch circuit includes an internal CPU, an internal register electrically connected to the internal CPU, an Ethernet port SGMII and several Ethernet PHYs, an Ethernet port MII electrically connected to the internal register, and a power supply module for the Ethernet switch circuit; the main control The unit is electrically connected to the power circuit through the GPIO interface; the power circuit is electrically connected to the power module of the Ethernet switch circuit; the main control unit is electrically connected to the Ethernet port MII of the Ethernet switch circuit through the Ethernet MII interface; the main control unit is also connected through the SMI The interface is electrically connected with internal registers of the Ethernet switch circuit. The invention solves the problem that the existing Ethernet gateway cannot be compatible with various electronic and electrical architectures.

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...
