And if the diagnosis result data obtained after the diagnosis of the vehicle data is the data to be displayed, the diagnosis result data is subjected to data encapsulation to obtain a vehicle data packet, and the step S202 and the subsequent steps are executed.
In step S202, the diagnostic software sends the vehicle data packet to the communication layer.
In step S203, the communication layer obtains a display interface corresponding to the vehicle data packet according to the vehicle data packet.

In one embodiment, the communication layer obtains a display interface corresponding to the vehicle data packet according to the vehicle data packet, including: and the communication layer acquires a prestored display interface corresponding to the display interface identifier according to the display interface identifier in the vehicle data packet.
Specifically, different types of display interface identifiers and corresponding display interfaces are preset, so that the corresponding display interfaces can be obtained according to the display interface identifiers.
In step S204, the communication layer transmits the vehicle data packet and the display interface to the message processing system through the shared memory.
Specifically, the communication layer transmits the vehicle data packet and the display interface to the message processing system in the mode of the shared memory.

Specifically, both the communication layer and the message processing system cache the data in the shared content, and directly read the data from the shared memory, so that the efficiency of information interaction can be improved.
In step S205, the message processing system creates a display interface according to the vehicle data packet and the display interface, and displays information corresponding to the vehicle data.
Specifically, the message processing system fills corresponding vehicle data in the display interface according to the vehicle data packet and the display interface and displays the corresponding vehicle data, so that the client can manufacture and display the corresponding diagnosis interface.
