Abstract

The invention relates to a security gateway, a data processing method and device, a vehicle network topology and a vehicle. The security gateway comprises one or more CAN bus interfaces, a first communication interface, a second communication interface and a control module, and is characterized in that the control module is used for acquiring data packets to be transmitted from one or more CAN buses through the one or more CAN bus interfaces and transmitting the data packets to be transmitted to a vehicle-mounted information system electronic control unit through the first communication interface so as to transmit the data packets to be transmitted to external equipment. The data packets to be transmitted, which are required to be transmitted to the external equipment, of a vehicle are transmitted to the vehicle-mounted information system electronic control unit through the security gateway, so that the data packets to be transmitted are transmitted to the external equipment, the network load can be reduced, and the stability of a vehicle system and the safety of the vehicle are ensured.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a security gateway, a data processing method, a device, a vehicle network system, and a vehicle. Background technique [0002] In the existing Internet of Vehicles technology, the vehicle network system is mostly composed of a single gateway-2 network segment or a single gateway-3 network segment, supplemented by a LIN network. The vehicle bus message data is sent from the vehicle information system (Telematics system) to an external device (for example, a server) through a mobile network (for example, a 4G network). [0003] see figure 1 , in the related art, the vehicle information system is arranged in the B-CAN network segment (that is, the network segment for transmitting vehicle body related data). The ECU nodes in the B-CAN network segment can directly send CAN messages to the vehicle information system. The data messages in other network segments n...
