The invention belongs to the field of vehicle-mounted Ethernet communication, and particularly relates to a vehicle-mounted Ethernet data access device. The vehicle-mounted Ethernet data access devicecomprises: a non-vehicle-mounted Ethernet bus connected with a non-vehicle-mounted Ethernet node; a vehicle-mounted Ethernet bus which is connected with the vehicle-mounted Ethernet node; a gateway which is internally provided with a non-vehicle-mounted Ethernet interface receiving and transmitting module which is connected with the non-vehicle-mounted Ethernet bus, a vehicle-mounted Ethernet interface receiving and transmitting module which is connected with the vehicle-mounted Ethernet bus, and a protocol conversion module is respectively connected with the non-vehicle-mounted Ethernet interface transceiving module and the vehicle-mounted Ethernet interface transceiving module. According to the invention, access and transmission of non-vehicle-mounted Ethernet data on the vehicle-mounted Ethernet are realized, so that data based on protocols such as CAN, LIN and the like and vehicle-mounted Ethernet protocol data can communicate with each other.
Description
technical field [0001] The invention belongs to the field of vehicle Ethernet communication, in particular to a vehicle Ethernet data access device. Background technique [0002] Traditional vehicle networks mainly include Controller Area Network (CAN) and Local Interconnect Network (LIN). CAN bus is a stable performance, mature technology, low cost and high reliability, and is widely used in vehicle networks. The LIN bus is suitable for applications with low communication speeds such as car windows, sunroofs, seats, and interior lighting. It can further reduce network costs while meeting communication speed requirements and not requiring CAN bus performance. It is usually used as a supplement to CAN bus The internet. With the continuous development of automobile intelligence and networking, and the application of emerging technologies such as automobile high-definition in-vehicle entertainment systems, car networking systems, cloud services, and big data, the on-board Eth...
