The remote assistance diagnosis method of the present embodiment is basically similar to the remote assistance diagnosis method of the previous embodiment, and differs therefrom in that: after the first diagnosis terminal receives the diagnosis protocol packet data sent by the platform server, the first diagnosis terminal sends the diagnosis protocol packet data to a vehicle to be diagnosed, which is connected with the first diagnosis terminal. After the vehicle to be diagnosed receives the diagnostic protocol packet data of the first diagnostic terminal, response information is usually generated according to the diagnostic protocol packet data. The first diagnosis terminal can receive or acquire the response information and send the response information to the platform server.

As shown in fig. 12, in an embodiment of the present invention, after step S131 or S135, the following steps are further included:

s136: the platform server receives response information sent by the first diagnosis terminal;

s137: the platform server verifies whether the diagnosis protocol according to the response information is consistent with the diagnosis protocol corresponding to the information of the vehicle to be diagnosed in the demand information;

s138: if the first diagnosis terminal is consistent with the remote connection channel established by the platform server, the first diagnosis terminal continues to be connected with the remote connection channel established by the platform server;

s139: and if the two are not consistent, the first mobile terminal receives the prompt message sent by the platform server.

Specifically, after receiving the response message sent by the first diagnosis terminal, the platform server may verify the response message to determine whether a diagnosis protocol followed by the response message sent by the first diagnosis terminal is consistent with a diagnosis protocol corresponding to the information of the vehicle to be diagnosed in the demand message.

The platform server can call the information of the vehicle to be diagnosed in the demand information, and inquire and obtain the diagnosis protocol type associated with the information of the vehicle to be diagnosed in the database according to the information of the vehicle to be diagnosed. Secondly, the platform server also analyzes the response information and obtains the diagnosis protocol type followed by the response information. And thirdly, the platform server can compare and verify the diagnosis protocol type corresponding to the information of the vehicle to be diagnosed with the diagnosis protocol type followed by the response information.

If the types of the diagnosis protocols corresponding to the first diagnosis terminal and the second diagnosis terminal are consistent, the first diagnosis terminal can continue to be connected with the remote connection channel established by the platform server, namely, the first diagnosis terminal can continue to be remotely connected with the second diagnosis terminal through the platform server. If the types of the diagnosis protocols corresponding to the first mobile terminal and the second mobile terminal are not consistent, the platform server sends prompt information to the first mobile terminal and/or the second mobile terminal, and the prompt information may include a prompt that the information of the vehicle to be diagnosed in the demand information is not matched with the diagnosis data transmitted by the first diagnosis terminal.
