Description

Technical Field

[0001] This invention relates to the field of vehicle networking technology, and in particular to a vehicle remote diagnostic method, remote diagnostic platform and system based on grayscale tasks. Background Technology

[0002] With the widespread adoption of vehicle-to-everything (V2X) technology, remote vehicle diagnostics has become a key technology for improving vehicle maintenance efficiency and user experience. Traditional remote vehicle diagnostics primarily operates in two modes: one where maintenance personnel proactively initiate the diagnostic process, and the other where a network platform proactively issues diagnostic commands. However, both modes largely function as reactive responses after a vehicle malfunction occurs or a fault code is generated, lacking predictability. This leads to increased vehicle downtime, as well as increased time and maintenance costs for vehicle owners.

[0003] Furthermore, existing vehicle remote diagnostic systems typically employ fixed diagnostic strategies, applying a uniform strategy to all vehicles without the ability to dynamically adjust based on vehicle type, usage environment, user needs, or other factors. The release of diagnostic strategies is often one-size-fits-all, failing to consider the differentiated needs of different users and vehicles. In addition, traditional diagnostic systems usually only provide simple results after diagnosis, lacking evaluation of diagnostic effectiveness and dynamic adjustments to subsequent strategies.

[0004] Therefore, there is an urgent need in this field for a remote diagnostic solution that can enable personalized configuration, canary release, and dynamic management of diagnostic tasks, in order to achieve early fault detection and preventive maintenance. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art, and proposes a vehicle remote diagnostic method, remote diagnostic platform, and system based on gray-scale tasks. It aims to address the problems of traditional remote diagnostic methods being passive, singular, and unable to be personalized or deployed in a gray-scale manner, thereby achieving on-demand, real-time, and preventative execution of diagnostic tasks.

These should be considered merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0041] Where there is no conflict, the various embodiments of the present invention and the features thereof may be combined with each other.

[0042] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0043] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, the singular forms “a” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded. Terms such as “connected” or “linked” are not limited to physical or mechanical connections but can include electrical connections, whether direct or indirect.

[0044] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having the meaning consistent with their meaning in the context of the relevant art and the invention, and will not be interpreted as having an idealized or overly formal meaning unless expressly so defined herein.

[0045] The relevant technologies have at least the following problems:

[0046] (1) Traditional vehicle remote diagnostic methods only perform diagnostics after a vehicle malfunctions, resulting in long downtime and high maintenance costs;

[0047] (2) Existing remote diagnostic systems lack differentiated diagnostic strategies for different vehicles and users;

[0048] (3) The release of diagnostic strategies lacks a gray-scale testing mechanism, making it impossible to dynamically optimize diagnostic strategies based on user feedback;

[0049] (4) Lack of evaluation of diagnostic effectiveness and dynamic adjustment of subsequent strategies after diagnosis.

[0050] To address at least one of the technical problems existing in the aforementioned related technologies, this invention provides a vehicle remote diagnostic method based on grayscale tasks. See also... Figure 1 as well as Figure 2 This includes the following steps:

[0051] S1 saves the vehicle relationship table and corresponding diagnostic strategies to the remote diagnostic platform.

[0052] Remote diagnostic platforms are typically staffed with administrators who manage and maintain them. Before executing the remote diagnostic method of this invention, the administrators pre-enter a vehicle relationship table into the remote diagnostic platform. This table primarily records basic vehicle information, such as brand, model number, and parts, with corresponding relationships between them. Specifically, each model number is located within its corresponding brand list, while parts are located within their corresponding model number list, thus forming a three-level index relationship. In one embodiment, the vehicle relationship table can also pre-store other vehicle information, such as the vehicle's production date (out-of-line date).

[0053] For diagnostic strategies, managers also pre-enter the data into the remote diagnostic platform. The diagnostic strategy includes diagnostic documents that record specific diagnostic methods. These documents need to be tagged with vehicle model, parts, and other information related to the vehicle's basic information, establishing a correspondence between them and the aforementioned vehicle relationship table.

[0054] In addition, administrators can publish gray-scale diagnostic tasks on the remote diagnostic platform. These tasks can select the diagnostic strategies mentioned above and vehicles recorded in the vehicle relationship table, thus allowing them to specify which vehicles should execute a particular strategy. Diagnostic tasks include immediate tasks and periodic tasks. Immediate tasks are fast-response tasks that require immediate execution and are usually one-time tasks. Periodic tasks, on the other hand, are routine diagnostics that are published periodically, requiring regular component diagnostics.

[0055] S2: The remote diagnostic platform acquires vehicle information and sends the corresponding diagnostic strategy to the corresponding vehicle to execute the diagnostic task.

[0056] The vehicle information acquired by the remote diagnostic platform is sent by the user's vehicle, and this sending action is automatically executed by the user's vehicle. For example, when the vehicle is registered (car ignition), the vehicle automatically reports vehicle information to the remote diagnostic platform. This vehicle information includes the vehicle model and all parts information, with the model corresponding to the brand and series in the vehicle relationship table. After receiving the vehicle information, the remote management platform first matches the vehicle information with diagnostic tasks, starting with matching the vehicle model. If a corresponding vehicle model is found in the published diagnostic task, the parts information is then matched with the diagnostic task. A successful match indicates that the remote diagnostic platform has a remote diagnostic task corresponding to that vehicle. In one embodiment, assuming the remote diagnostic task needs to target vehicles manufactured within a specific time period, the vehicle's production date also needs to be matched with the production date corresponding to the remote diagnostic task during model matching. This allows for remote diagnostics of specific parts for a specific vehicle model and production time.

[0057] When a remote diagnostic platform issues a remote diagnostic task for a corresponding vehicle, it generates a remote diagnostic task list and sends this list to the vehicle. The remote diagnostic task list includes a diagnostic strategy, which may include one or more diagnostic methods. Upon receiving the remote diagnostic task list, the vehicle user can select the appropriate diagnostic method. Of course, the user can also change the diagnostic strategy as needed.

[0058] In the preferred embodiment, the diagnostic strategies recorded in the remote diagnostic task list can be categorized by importance, for example, into three levels: Level 1 is the most important, Level 2 is next, and Level 3 is relatively less important. For Level 1 diagnostic strategies, which have high importance, the user cannot change the strategy, and the user is reminded to ensure the vehicle performs the diagnostic task within a certain timeframe. For Level 2 diagnostic strategies, the user can change the strategy as needed. For Level 3 diagnostic strategies, the user can ignore them on the vehicle side, meaning the diagnostic task will not be executed.

[0059] After the user confirms the execution of the diagnostic task, the vehicle terminal queries the remote diagnostic platform for the corresponding task policy. The remote diagnostic platform then returns the policy information to the vehicle terminal and provides a download address for the diagnostic script. The vehicle terminal downloads the diagnostic script based on the download address provided by the remote diagnostic platform.

[0060] After the diagnostic script is downloaded to the vehicle, the vehicle can indicate the execution time of the diagnostic task, such as immediate execution or preset execution time. Once the execution time is reached, the vehicle begins executing the remote diagnostic task according to the strategy. During the diagnostic process, the vehicle only needs to report the progress of the diagnostic task to the remote diagnostic platform, collect remote diagnostic logs, and report the log storage path to the remote diagnostic platform.

[0061] S3, the remote diagnostic platform generates a diagnostic report based on the diagnostic logs sent by the vehicle terminal, and sends the diagnostic report to the vehicle terminal when an anomaly is detected.

[0062] In this invention, the remote diagnostic platform has an analysis function. After the diagnostic task on the vehicle is completed, the remote diagnostic platform can download the diagnostic log, analyze the log, and generate a remote diagnostic report. The remote diagnostic report displays the key indicator parameters generated by the corresponding diagnostic task, as well as the range thresholds of these parameters. Based on the comparison between the two, the diagnostic result of this diagnostic task is given.

[0063] The remote diagnostic platform automatically sends the generated remote diagnostic report to the vehicle, where the owner can view the diagnostic results. Alternatively, if the diagnostic results are satisfactory, the remote diagnostic platform may not send a report to the vehicle; however, if the diagnostic results are abnormal, the platform will automatically send a report to the vehicle.

[0064] In the preferred solution, users can provide feedback on the remote diagnostics to the remote diagnostic platform from the vehicle.

[0065] This invention relates to remote vehicle diagnostics based on gray-scale tasks. First, the diagnostic system administrator inputs basic data information such as vehicle model, series, vehicle, and parts, and binds the corresponding parts relationships for each series and model, and inputs the corresponding CAN network bus service information for the vehicle. Then, a corresponding remote diagnostic strategy is configured for the vehicle requiring remote diagnostics. After configuring the specific strategy, a corresponding vehicle diagnostic task is configured, binding the remote diagnostic strategy to the specified vehicle and publishing the task. Various task types can be configured, such as immediate tasks and periodic tasks. When the user starts the vehicle, they report vehicle and parts information to the remote diagnostic platform. The platform queries the remote diagnostic task list corresponding to that vehicle model. If the platform has configured a remote diagnostic task for that vehicle, and the parts type in the task strategy matches the parts type information reported by the vehicle, it returns a list of qualified diagnostic tasks for the user to choose from. After selecting the corresponding task, the user queries the diagnostic platform for the remote diagnostic strategy, downloads the corresponding diagnostic script, and then executes the diagnostic task according to the strategy. Finally, diagnostic logs are uploaded to the cloud. The remote diagnostic system analyzes and evaluates the diagnostic logs. If any abnormalities are found in the vehicle diagnostics, a report is proactively pushed to the vehicle owner. This concludes the vehicle remote diagnostic process based on the grayscale task.

[0066] See Figure 3 Based on the same inventive concept, this embodiment of the invention also provides a vehicle remote diagnostic platform based on grayscale tasks, used to implement the above diagnostic method, including: a storage unit, a publishing unit, and an analysis unit.

[0067] The storage unit is used to pre-store vehicle relationship tables and corresponding diagnostic strategies.

[0068] Specifically, remote diagnostic platforms are typically staffed with administrators who pre-enter vehicle relationship tables into the platform. These tables primarily record basic vehicle information, such as brand, model number, and parts. Diagnostic strategies include diagnostic documents that detail specific diagnostic methods. These documents must also tag vehicle models, parts, and other information related to the vehicle's basic information, establishing a correspondence between these tags and the aforementioned vehicle relationship tables.

[0069] The publishing unit is used to publish and send diagnostic tasks to the vehicle.

[0070] The gray-scale diagnostic task can select the diagnostic strategies mentioned above and the vehicles recorded in the vehicle relationship table, and then specify the vehicles to execute the specified strategies, and publish the diagnostic task on the remote diagnostic platform.

[0071] After the remote management platform receives vehicle information from the vehicle, it first matches the vehicle information with diagnostic tasks, starting with the vehicle model. If a corresponding vehicle model is found in the published diagnostic tasks, it then matches the parts information with the diagnostic tasks. If a match is successful, it indicates that the remote diagnostic platform has a remote diagnostic task corresponding to that vehicle. The remote diagnostic platform then generates a list of remote diagnostic tasks and sends this list to the vehicle.

[0072] After the user confirms the execution of the diagnostic task, the vehicle queries the remote diagnostic platform for the corresponding task policy. The remote diagnostic platform then returns the policy information to the vehicle and provides a download address for the diagnostic script.

[0073] The analysis unit generates a diagnostic report based on the diagnostic logs sent from the vehicle.

[0074] Once the vehicle-side diagnostic task is completed, the remote diagnostic platform can download and analyze the diagnostic logs, generating a remote diagnostic report. The remote diagnostic report displays the key indicator parameters generated by the corresponding diagnostic task, along with the threshold ranges for those parameters. Based on a comparison of these two data points, the diagnostic result for this task is given.

[0075] The remote diagnostic platform automatically sends the generated remote diagnostic report to the vehicle, where the owner can view the diagnostic results. Alternatively, if the diagnostic results are satisfactory, the remote diagnostic platform may not send a report to the vehicle; however, if the diagnostic results are abnormal, the platform will automatically send a report to the vehicle.

[0076] See Figure 2Based on the same inventive concept, this invention also provides a vehicle remote diagnostic system based on grayscale tasks, including a vehicle-side terminal and a remote diagnostic platform. The remote diagnostic platform is implemented using the above-described method, specifically:

[0077] Save the vehicle relationship table and corresponding diagnostic strategies to the remote diagnostic platform;

[0078] The vehicle sends vehicle information to the remote diagnostic platform, and the remote diagnostic platform sends the corresponding diagnostic strategy to the corresponding vehicle. The vehicle then executes the diagnostic task according to the diagnostic strategy.

[0079] The vehicle sends diagnostic logs to the remote diagnostic platform, which then generates a diagnostic report based on the logs.

[0080] The diagnostic system provided in this invention can provide flexible diagnostic methods for diverse data generated by different vehicle models, different driving habits, and different environmental conditions, enabling the gray-scale release of tasks and further formulating release strategies based on the usage and feedback evaluation of the gray-scale data.

[0081] Based on the same inventive concept, embodiments of the present invention also provide an electronic device. Figure 4 This is a structural block diagram of an electronic device provided in an embodiment of the present invention. Figure 4 As shown, an embodiment of the present invention provides an electronic device including: one or more processors 101, a memory 102, and one or more I / O interfaces 103. The memory 102 stores one or more programs, which, when executed by the one or more processors, enable the one or more processors to implement any of the grayscale task-based remote vehicle diagnostic methods described in the above embodiments; the one or more I / O interfaces 103 are connected between the processor and the memory, configured to enable information interaction between the processor and the memory.

[0083] In some embodiments, the processor 101, memory 102, and I / O interface 103 are interconnected via bus 104, and thus connected to other components of the computing device.

[0084] In some embodiments, the one or more processors 101 include a field-programmable gate array.

[0085] This invention also provides a computer-readable medium. The computer-readable medium stores a computer program, which, when executed by a processor, implements the steps in any of the grayscale task-based remote vehicle diagnostics described in the above embodiments. The computer-readable storage medium can be volatile or non-volatile.

[0086] Beneficial effects:

[0087] 1. Real-time and preventative: Through an immediate or periodic task triggering mechanism, the vehicle can be remotely diagnosed regularly and in real time, thereby discovering potential problems in time before a fault occurs or worsens, changing "post-event remediation" to "pre-event prevention", effectively saving car owners' time and maintenance costs.

[0088] 2. By flexibly configuring diagnostic strategies and task bindings, differentiated diagnostics can be achieved for different users, vehicle models, and parts groups, enabling the "gray-scale" release of diagnostic tasks. The platform can further evaluate and adjust diagnostic strategies based on usage data and feedback from gray-scale users, achieving precision and iterative optimization.

[0089] 3. Users can choose the diagnostic items they want to perform from the matching task list pushed by the platform according to their own needs, which enhances user participation and the level of service personalization.

[0090] 4. Strong system scalability: The architecture design of this invention enables the system to easily expand with new diagnostic strategies and tasks, adapting to the future development of vehicle technology.
