[0037] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] In order to accurately obtain the diagnostic routing address of the first controller in the target vehicle, an embodiment of the present disclosure provides a vehicle diagnostic method.

[0040] Specifically, in response to a diagnostic request for a first controller in a target vehicle, a query is made from a first configuration directory in the target vehicle whether there is a diagnostic routing configuration file of the vehicle model to which the target vehicle belongs; wherein the first configuration directory is a pre-set directory for storing diagnostic routing configuration files of the vehicle model to which the target vehicle belongs, and the diagnostic routing configuration file includes diagnostic routing addresses corresponding to each controller in the target vehicle. When it is determined that there is a diagnostic routing configuration file of the vehicle model to which the target vehicle belongs in the first configuration directory, the diagnostic routing configuration file is obtained, the diagnostic routing configuration file is loaded, and the diagnostic routing address of the first controller is obtained, wherein the diagnostic routing address is used to diagnose the first controller. It can be seen that the embodiment of the present disclosure obtains the diagnostic routing configuration file of the vehicle model to which the target vehicle belongs with the vehicle model as the granularity by determining the diagnostic routing configuration file of the vehicle model to which the target vehicle belongs from the directory storing the diagnostic routing configuration file of the vehicle model to which the target vehicle belongs. By loading the diagnostic routing configuration file, the diagnostic routing address of the first controller in the target vehicle can be accurately obtained, which effectively solves the problem of different diagnostic routing addresses corresponding to the same controller in different vehicle models.

[0041] Based on this, the present disclosure provides a vehicle diagnosis method, referring to Figure 1 , is a flow chart of a vehicle diagnostic method provided by an embodiment of the present disclosure, the method comprising:

[0042] S101: In response to a diagnosis request for a first controller in a target vehicle, query a first configuration directory in the target vehicle to see whether there is a diagnosis routing configuration file of a vehicle model to which the target vehicle belongs.

[0043] The first configuration directory is a pre-set directory for storing a diagnostic routing configuration file of a vehicle type to which the target vehicle belongs, and the diagnostic routing configuration file includes a diagnostic routing address corresponding to each controller in the target vehicle.

[0044] The vehicle diagnosis method provided in the embodiments of the present disclosure can be applied to scenarios where the same controllers of multiple vehicle models have different corresponding diagnosis routing addresses.

[0045] In the disclosed embodiment, the diagnostic routing configuration file includes the correspondence between the controller identifier of the target vehicle model, the diagnostic routing address, and the routing configuration information, wherein the routing configuration information refers to the configuration information related to the diagnostic parameters required on the diagnostic link, such as routing network segment information, routing IP (Internet Protocol Address), etc.

[0046] In the disclosed embodiment, the first controller may be any controller in the target vehicle, such as an air-conditioning controller, an engine controller, a body controller, etc. Accordingly, the diagnostic routing addresses corresponding to the various controllers in the target vehicle are used to realize communication between the diagnostic tool and the corresponding controller in the target vehicle, so that the diagnostic tool can access the corresponding controller based on the diagnostic routing address, thereby realizing diagnosis of the controller.

[0047] In the disclosed embodiment, since the first configuration directory exists in the target vehicle, and the first configuration target is a pre-set directory for storing the diagnostic routing configuration files of the vehicle model to which the target vehicle belongs, when a diagnostic request from the first controller in the target vehicle is received, it is sufficient to directly query whether there is a diagnostic routing configuration file of the vehicle model to which the target vehicle belongs from the access path based on the first configuration directory in the target vehicle, without having to search for the diagnostic routing configuration file based on the vehicle identification of the target vehicle, such as VIN (Vehicle Identification Number), that is, skipping the process of searching based on the vehicle identification, reducing additional query steps, and shortening the time for obtaining the diagnostic routing configuration file.

[0048] Specifically, in response to a diagnostic request for a first controller in a target vehicle, before querying whether there is a diagnostic routing configuration file for the model of the target vehicle in the first configuration directory in the target vehicle, the diagnostic routing configuration file can be saved in the first configuration directory of the target vehicle.

[0049] In an optional implementation, when it is detected that the diagnostic service of the target vehicle is started, a request for a diagnostic routing configuration file of the model to which the target vehicle belongs is sent to a remote background server, a response message returned by the remote background server to the diagnostic routing configuration file request is received, and the diagnostic routing configuration file is saved to the first configuration directory of the target vehicle.

[0050] The diagnostic routing configuration file request is used to request the remote background service to return the diagnostic routing configuration file of the model of the target vehicle, and the response message carries the diagnostic routing configuration file of the model of the target vehicle.

[0051] In the embodiments of the present disclosure, the remote background server refers to a server used to provide services and resources such as diagnostic routing configuration files. Specifically, the remote background server can be any type of server such as a cloud server, etc. The embodiments of the present disclosure do not impose any limitation on the type of the remote background server.

[0052] In the disclosed embodiment, when it is detected that the diagnostic service of the target vehicle is started, the diagnostic routing configuration file of the model to which the target vehicle belongs can be obtained by sending a diagnostic routing configuration file request for the model to which the target vehicle belongs to a remote background server, and the diagnostic routing configuration file is saved in the first configuration directory of the target vehicle, so that when a diagnostic request for the first controller in the target vehicle is received, the diagnostic routing configuration file of the model to which the target vehicle belongs can be queried from the first configuration directory.

[0053] In an optional implementation, the diagnostic routing profile request may carry a vehicle identification of the target vehicle, so that when the remote background server receives the diagnostic routing profile request, it can determine the model identification of the target vehicle from the vehicle database based on the target vehicle identification, and determine the diagnostic routing profile of the model of the target vehicle based on the target vehicle identification.

[0054] In the disclosed embodiment, the diagnostic routing configuration file request is used to request the remote background server to determine the model identification of the target vehicle based on the vehicle identification of the target vehicle, and return the diagnostic routing configuration file of the model of the target vehicle based on the model identification of the target vehicle.

[0055] After the remote background server obtains the diagnostic routing configuration file of the model to which the target vehicle belongs, it can request a response message returned from the diagnostic routing configuration file, so that after receiving the response message, the target vehicle can parse the response message to obtain the diagnostic routing configuration file of the model to which the target vehicle belongs, and save the diagnostic routing configuration file to the first configuration directory of the target vehicle.

[0056] In addition, in order to obtain the diagnostic routing configuration file of the target vehicle model from the remote background server when the target vehicle model is a new model launched by the automobile manufacturer, in an optional implementation, the remote background server can update the diagnostic routing configuration file library based on the update frequency.

[0057] Specifically, the diagnostic routing configuration file library includes a correspondence between vehicle type identifications and diagnostic routing configuration files.

[0058] In the embodiment of the present disclosure, the update frequency refers to the time interval for updating the diagnosis routing configuration file library.

[0059] In another optional implementation, the remote background server may also update the diagnostic routing configuration file library when receiving a new vehicle model release request or a diagnostic routing configuration file change request.

[0060] S102: When it is determined that a diagnostic routing configuration file of the vehicle type to which the target vehicle belongs exists in the first configuration directory, the diagnostic routing configuration file is obtained.

[0061] In the disclosed embodiment, since the first configuration directory is a pre-set directory for storing the diagnostic routing configuration files of the model to which the target vehicle belongs, when it is determined that the diagnostic routing configuration files of the model to which the target vehicle belongs exist under the first configuration directory, the diagnostic routing configuration files can be directly obtained based on the access path of the first configuration directory.

[0062] In the disclosed embodiment, when a request to change a diagnostic routing configuration file of a target vehicle type is received, the diagnostic routing configuration file of the target vehicle type can be directly changed without affecting the diagnostic routing configuration files of other vehicle types.

[0063] In addition, when the remote background server fails to send the diagnostic routing configuration file of the model of the target vehicle to the first configuration directory in the target vehicle, in order to obtain the diagnostic routing configuration file of the model of the target vehicle, in an optional implementation, when it is determined that the diagnostic routing configuration file of the model of the target vehicle does not exist in the first configuration directory, it is possible to query whether the diagnostic routing configuration file of the model of the target vehicle exists in the second configuration directory, thereby obtaining the diagnostic routing configuration file when it is determined that the diagnostic routing configuration file of the model of the target vehicle exists in the second configuration directory.

[0064] The second configuration directory is a pre-set directory for storing the correspondence between the vehicle model identification and the diagnostic routing configuration file.

[0065] In the disclosed embodiment, the second configuration directory is different from the first configuration directory. Specifically, the second configuration directory can be understood as a backup configuration directory, which can ensure that even when the diagnostic routing configuration file of the target vehicle model does not exist in the first configuration directory, the corresponding diagnostic routing configuration file can still be obtained and vehicle diagnosis can continue.

[0066] In an optional implementation, before querying from the second configuration directory whether there is a diagnostic routing configuration file for the model of the target vehicle, the entire vehicle configuration word information of the target vehicle can also be obtained, and the model identification of the target vehicle can be determined from the entire vehicle configuration word information, thereby querying from the second configuration directory whether there is a diagnostic routing configuration file for the model of the target vehicle based on the model identification of the target vehicle.

[0067] In the disclosed embodiment, the vehicle configuration word includes a vehicle model, configuration options, controller information, etc. Specifically, the vehicle model identification of the target vehicle can be determined by parsing the vehicle configuration word information of the target vehicle, and then based on the vehicle model identification of the target vehicle, it is possible to query whether there is a diagnostic routing configuration file of the vehicle model to which the target vehicle belongs from the correspondence between the vehicle model identification and the diagnostic routing configuration file stored in the second configuration directory.

[0068] In addition, in order to ensure the continuity of the program, in an optional implementation, when it is determined that the diagnostic routing configuration file of the model of the target vehicle does not exist in the second configuration directory, the preset diagnostic routing configuration file in the second configuration directory is used as the diagnostic routing configuration file of the model of the target vehicle.

[0069] The preset diagnostic routing configuration file may be any diagnostic routing configuration file under the second configuration directory, and the embodiment of the present disclosure does not impose any limitation thereto.

[0070] S103: Load the diagnostic routing configuration file to obtain the diagnostic routing address of the first controller.

[0071] The diagnostic routing address is used to diagnose the first controller.

[0072] In the disclosed embodiment, after obtaining the diagnostic routing configuration file of the model to which the target vehicle belongs, the diagnostic routing configuration file of the model to which the target vehicle belongs can be loaded by using the first controller identifier carried in the diagnostic request of the first controller in the target vehicle to obtain the diagnostic routing address of the first controller. There is no need to load the diagnostic routing configuration files of the models to which other vehicles belong, thereby reducing the processing of invalid information and improving the loading efficiency of the diagnostic routing configuration files.

[0073] In the vehicle diagnosis method provided by the present disclosure, in response to a diagnosis request for a first controller in a target vehicle, a query is made from a first configuration directory in the target vehicle whether there is a diagnostic routing configuration file of the vehicle model to which the target vehicle belongs; wherein the first configuration directory is a pre-set directory for storing diagnostic routing configuration files of the vehicle model to which the target vehicle belongs, and the diagnostic routing configuration file includes diagnostic routing addresses corresponding to each controller in the target vehicle. When it is determined that there is a diagnostic routing configuration file of the vehicle model to which the target vehicle belongs in the first configuration directory, the diagnostic routing configuration file is obtained, the diagnostic routing configuration file is loaded, and the diagnostic routing address of the first controller is obtained, wherein the diagnostic routing address is used to diagnose the first controller. It can be seen that the embodiment of the present disclosure obtains the diagnostic routing configuration file of the vehicle model to which the target vehicle belongs with the vehicle model as the granularity by determining the diagnostic routing configuration file of the vehicle model to which the target vehicle belongs from the directory storing the diagnostic routing configuration file of the vehicle model to which the target vehicle belongs, and by loading the diagnostic routing configuration file, the diagnostic routing address of the first controller in the target vehicle can be accurately obtained, which effectively solves the problem that the diagnostic routing addresses corresponding to the same controller in different vehicle models are different.
