Abstract

The invention provides a vehicle-mounted communication system and a vehicle, and the vehicle-mounted communication system comprises a vehicle-mounted gateway which is used for receiving a VLAN (Virtual Local Area Network) identifier and an IP (Internet Protocol) address corresponding to each port in the pre-configured vehicle-mounted gateway, and transmitting the VLAN identifier and the IP address to the vehicle-mounted gateway; corresponding virtual local area network (VLAN) identifications and internet protocol (IP) addresses are distributed to the vehicle-mounted devices connected with the ports respectively, the vehicle-mounted devices distributed with the same VLAN identifications are located in the same VLAN group, and one VLAN group comprises one or more vehicle-mounted devices; and any vehicle-mounted device is used for communicating with other vehicle-mounted devices according to the allocated virtual local area network VLAN identifier and the IP address. According to the invention, the VLAN groups are divided for the plurality of vehicle-mounted devices connected with the vehicle-mounted gateway, so that VLAN grouping isolation of the vehicle-mounted gateway can be realized, and the information security of the gateway is enhanced. Moreover, the network load can be reduced, and the network storm can be reduced.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a vehicle-mounted communication system and a vehicle. Background technique [0002] There are more and more in-vehicle devices connected to the in-vehicle Ethernet gateway, the amount of data is larger and larger, and the requirements for information security are getting higher and higher. If any in-vehicle device connected to the in-vehicle Ethernet gateway is attacked, or information data is stolen, other in-vehicle devices will not be spared, which is an undesired result. Based on this, how to improve the information security between in-vehicle devices is a problem that needs to be considered. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an in-vehicle communication system and a vehicle to improve information security between in-vehicle devices. [0004] In order to achieve the above object, the present invention provides an in-ve...
