And step 34, the data transmission device performs system scanning on the vehicle through the connection socket to obtain at least one system to be diagnosed of the vehicle.
Specifically, the MCU in the data transmission device sends a detection request to the ECUs in the vehicle through the connection socket, and each ECU in the vehicle returns a detection response carrying the identification of the ECU after receiving the detection request, so that the data transmission device determines the number, the working state (on state or off state) and the like of the system to be diagnosed.

The method adopts a multichannel vehicle diagnosis method technology, greatly shortens the vehicle diagnosis test time, and the generated diagnosis result can support data review, so that the timeliness of diagnosis software is improved, and meanwhile, the checking analysis of vehicle data and the vehicle maintenance efficiency of a customer are facilitated.
In some embodiments, to achieve scalability of the connection plug in the data transmission device, the vehicle diagnostic request may further include model information of the vehicle;

Further, before the data transmission device searches the stored comparison table between the different vehicle type information and the socket connection pins, the comparison table between the stored different vehicle type information and the different communication protocols can be searched first to obtain a target communication protocol corresponding to the vehicle type information;
after the data transmission device searches the stored comparison table between different vehicle type information and socket connection pins, the socket connection pins in the connection plug are switched to target socket connection pins, and the target socket connection pins are controlled to support a target communication protocol, so that the connection plug of the data transmission device is connected with the connection socket on the vehicle.
The implementation mode not only realizes the expandability of the connecting plug, but also realizes the compatibility of protocols in data transmission.
In some embodiments, the data transmission device may control connection and disconnection of the connection plug to the connection socket on the vehicle through the connection control module in response to the received connection control request.
In some embodiments, in step 35, for any diagnostic channel, if the data transmission device does not receive the diagnostic data of the corresponding system to be diagnosed fed back by the diagnostic channel within the preset timeout period after sending the diagnostic instruction to the corresponding system to be diagnosed through the diagnostic channel, the execution step is returned to: sending a diagnosis instruction to a corresponding system to be diagnosed through a diagnosis channel until the number of return execution reaches a preset number threshold, such as 5 times;
If the number of times of return execution reaches the preset number of times threshold, the data transmission device can send indication information that the corresponding system to be diagnosed is not diagnosed successfully to the vehicle diagnosis equipment, and the diagnosis personnel can perform manual diagnosis based on the indication information.
In some embodiments, if the number of the systems to be diagnosed is greater than the number of the diagnostic channels, the data transmission device allocates one diagnostic channel to each system to be diagnosed according to the stored diagnostic priority identifiers of different systems to be diagnosed, and performs the steps of: sending diagnosis instructions to corresponding systems to be diagnosed through all diagnosis channels;

It should be noted that, the diagnosis priority identifiers of different systems to be diagnosed may be predetermined based on the service requirement, or may be predetermined according to the protocols supported by different systems to be diagnosed, for example, the type priority identifiers corresponding to the protocol type 1-CAN protocol, the protocol type 2-KWP fast, and the protocol type 3-KWP address codes are 1, 2, and 3, respectively; i.e. the smaller the number identification, the higher the priority of the corresponding protocol type. Since the protocol processing speed of the protocol type 1-CAN protocol is relatively fastest, the overall diagnostic time CAN be reduced by arranging this type of electronic control system for the preceding processing.
