In an embodiment, the diagnostic device is first connected to the gateway controller via a standard OBD interface in the vehicle, and the gateway controller enters the extended mode by sending a diagnostic command (e.g., the diagnostic command may be 1003). Since the mirror configuration data needs to be written into the EEPROM through the data writing service (e.g., 2E service), so that the mirror configuration can also be valid after the gateway controller is reset, the security access needs to be performed through the security verification service (e.g., 27 service) in the foregoing to ensure the security. After the Mirror image configuration data is successfully written, the gateway controller judges the ethernet channel (i.e. the target ethernet ECU in the above embodiment) that needs to be mirrored, and sets the Mirror image (Mirror) function of the switch chip (e.g. Marvell 88Q5050 and 88Q5072) in the gateway controller through configuration driver software, and mirrors all the transmit-receive messages on the corresponding ethernet port to the 100Base-TX interface (i.e. the OBD ethernet channel in the above embodiment) of the OBD. Therefore, after the computer is connected to the OBD Ethernet interface through the network cable, the receiving and sending messages of the corresponding Ethernet channel can be received.
According to the technical scheme of the embodiment, the in-vehicle communication data is forwarded to the standard OBD interface by means of the route forwarding characteristic of the gateway controller, so that the purpose of reading and viewing the in-vehicle communication data is achieved on the premise of not increasing hardware cost.
