The application can also be implemented or applied in different specific embodiments, and various modifications or changes can be made to the details in the specification based on different viewpoints and applications without departing from the spirit of the application. It should be understood that the preferred embodiments are only for illustrating the application, and are not intended to limit the protection scope of the application.

[0029] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the application, and only the components related to the application are shown in the diagrams, rather than the number, shape, and size of the components when actually implemented. The shapes, numbers, and proportions of the components when actually implemented can be arbitrarily changed, and the layout pattern of the components can also be more complex.

[0030] As shown in Figures 1-2 The embodiment proposes a method for synchronizing vehicle configuration words, which comprises the following steps:

[0031] A domain controller is selected, a vehicle end configuration center is established in the selected domain controller, and a configuration word cloud database is established in the cloud, and the vehicle end configuration center and the configuration word cloud database store configuration word data of the vehicle;

[0032] When a functional configuration change is made, a functional configuration change request is sent to the vehicle end configuration center, and the functional configuration change request includes the changed configuration word data. Figure 2 The vehicle end configuration center analyzes the changed configuration word data, compares the changed configuration word data with the stored configuration word data, stores the changed configuration word data, and synchronously updates the changed configuration word data to other domain controllers and node controllers of the domain controllers. Figure 2 The vehicle end configuration center synchronously updates the changed configuration word data to the configuration word cloud database for backup. Figure 2

[0033] When the vehicle end controller is replaced or the configuration word data is lost, the vehicle end configuration center sends an acquisition request to the configuration word cloud database, and the configuration word cloud database downloads the configuration word data to the vehicle end configuration center. Figure 2 The vehicle end configuration center analyzes the configuration word data, compares the configuration word data with the stored configuration word data, stores the configuration word data, and then synchronously updates the configuration word data to other domain controllers and node controllers of the domain controllers.

[0034] By establishing a vehicle end configuration center in a domain controller, receiving the changed configuration word of a user, analyzing, comparing with the stored configuration word data, storing, and then synchronously updating to other domain controllers, node controllers, and the configuration word cloud database, the configuration function can be changed after the user sends a configuration change request, and the configuration word can be updated in the cloud and locally and stored. When the local configuration word is lost or the vehicle end controller is replaced, the latest configuration word data can be downloaded from the configuration word cloud database to realize real-time updating of the vehicle configuration word at the user end, which is convenient and efficient.

[0035] During normal use of the vehicle, after the vehicle function configuration is changed at the vehicle end or the mobile phone end, all domain controllers of the vehicle always maintain consistent configuration word data and function performance, and the changed configuration word data is also stored in the TSP (Telematics Service Provider) platform for backup.

[0036] The domain controller includes a cockpit domain controller, a vehicle control domain controller, and a driving domain controller, and the cockpit domain controller is selected to establish the vehicle end configuration center.

[0037] ​In this embodiment, the lower hanging node controller includes all lower hanging node controllers of the cockpit domain controller, the vehicle control domain controller and the driving domain controller. The vehicle end configuration center updates the configuration word data and synchronizes it to the lower hanging node controller. The lower hanging node controller is responsible for storage and functional application.

[0038] In this embodiment, the cockpit domain controller includes a T-BOX (Telematics BOX, vehicle networking system). The T-BOX establishes a vehicle end configuration center, receives configuration change requests from the cloud, the cockpit domain controller, the vehicle control domain controller and the driving domain controller, analyzes the changed configuration word data, compares it with the stored configuration word data, stores it, and synchronously updates the changed configuration word data to other domain controllers and the lower hanging node controllers of each domain controller, such as Figure 2 The middle path 5, 6, 7, 8, 9; at the same time, the function switching is completed, the vehicle end configuration center synchronously updates the changed configuration word data to the configuration word cloud database for backup, such as Figure 2 The middle path 11, after replacing the controller, requests the cloud configuration center to issue the configuration word data, and completes the synchronous update of the configuration word data and the function.

[0039] In this embodiment, the vehicle control domain controller is used to send vehicle control related function configuration change requirements to the vehicle end configuration center, such as "whether the driving lock is turned on" and other vehicle control related functions set on the display control screen of the cockpit host. At the same time, the vehicle end configuration center synchronously updates the configuration word to the vehicle control domain controller. The vehicle control domain controller is responsible for storage and functional application.

[0040] The driving domain controller is used to send driving related function configuration change requests to the vehicle end configuration center, such as "whether the APA (Auto Parking Assist, automatic parking) is turned on" and other driving related functions set on the display control screen of the cockpit host. At the same time, the vehicle end configuration center synchronously updates the configuration word data to the driving domain controller. The driving domain controller is responsible for storage and functional application.

[0041] The function configuration change request includes a request generated by changing the function configuration of the domain controller using a diagnostic instrument or an upper computer, a request generated by setting the function on the display control screen of the cockpit host, a request generated by mobile remote control, and a request generated when a mobile terminal or vehicle end purchases a function option package.

[0042] When the function configuration is changed, the signals received by the domain controller where the vehicle-side configuration center is located include vehicle-side application communication messages, diagnostic communication signals, OTA (Over-the-Air Technology) data flashing signals, and configuration word data. Conflict management is performed on the conflicts caused by the multiple signals received by the domain controller where the vehicle-side configuration center is located. When the conflict management is performed, the vehicle-side application communication messages, diagnostic communication signals, OTA data flashing signals, and configuration word data are sorted according to the priority of entering the domain controller, and the vehicle-side application communication messages, diagnostic communication signals, OTA data flashing signals, and configuration word data enter the domain controller in sequence.

[0043] The vehicle-side configuration center communicates with the configuration word cloud database through the Internet of Vehicles to synchronize and update the configuration word data of the vehicle-side configuration center to the configuration word cloud database.

[0044] After the vehicle-side configuration center synchronously updates the changed configuration word data to other domain controllers and the node controllers of each domain controller, the vehicle-side configuration center communicates with the other domain controllers or the node controllers of each domain controller based on the UDS diagnostic protocol. Through the UDS diagnostic protocol, the vehicle-side configuration center transmits CAN (Controller Area Network), CANFD (CAN with Flexible Data Rate), DOIP (Diagnostic over Internet Protocol), or DDS (Data Distribution Service) data packets to the other domain controllers or the node controllers of each domain controller.

[0045] After the vehicle-side configuration center synchronously updates the changed configuration word data to the configuration word cloud database for backup, the configuration word cloud database sends the backup result to the vehicle-side configuration center. For example, Figure 2 In the middle path 12, the backup result is whether the configuration word data backup is successful. If the backup is successful, the backup is stopped. If the backup is not successful, the backup is continued when the vehicle-side configuration center communicates with the configuration word cloud database through the Internet of Vehicles next time.

[0046] The present application is based on the current intelligent network connected vehicle electronic and electrical architecture, and all vehicle controllers are divided into two layers, the upper layer controller is generally an Ethernet node controller, including a cloud, a cabin domain controller, a vehicle control domain controller and a driving domain controller, and the lower layer controller is generally a CAN / LIN node controller hung under the upper layer controller. After the user triggers the configuration word data change during the use of the vehicle, the vehicle end configuration center receives the function configuration change request, analyzes, compares and stores the changed configuration word data, and then synchronously updates the changed configuration word data to other domain controllers and the hung node controller, and synchronously performs function configuration change, completes vehicle function switching, and the vehicle end configuration center needs to synchronously update the configuration word data to the configuration word cloud database for configuration word data backup and receives the backup result. When the controller replacement occurs at the vehicle end or the configuration word data is lost, the backup configuration word data can be downloaded to the vehicle end configuration center to ensure the normal operation of the vehicle related functions

[0047] As shown in Figure 3 The present application also provides a vehicle configuration word synchronization system, which comprises:

[0048] The cloud 101 sends the function configuration change request of the mobile end to the vehicle end configuration center 102 or receives the configuration word data uploaded by the vehicle end and stores the configuration word data, and downloads the configuration word data to the vehicle end configuration center 102.

[0049] The vehicle end configuration center 102 is used for receiving the function configuration change request, and synchronously updating the changed configuration word data to other domain controllers and the hung node controllers of each domain controller by analyzing, comparing and storing the configuration word data, and the stored configuration word data is also synchronously updated to the cloud 101, and the vehicle end configuration center 102 is also used for requesting the cloud 101 to download the configuration word data.

[0050] The present application also provides a computer storage medium, which stores a computer program, and the computer program is executed by a processor to make the processor execute the vehicle configuration word synchronization method of any one of the above.

[0051] The present application also provides a computer device, which comprises a memory and a processor, and the memory stores a computer program, and the computer program is executed by the processor to make the processor execute the vehicle configuration word synchronization method of any one of the above.

[0052] In summary, the embodiment of the present application provides a convenient and efficient vehicle configuration word synchronization method, system, storage medium and equipment, by establishing a vehicle end configuration center in the domain controller, receiving the changed configuration word of the user, performing analysis, comparing with the stored configuration word data, storing and synchronizing to other domain controllers, the hanging node controller and the configuration word cloud database, after the user issues a configuration change request, the transformation of the configuration function can be realized, at the same time, the configuration word can be updated and stored in the cloud and the local, when the local configuration word is lost or the vehicle end controller is replaced, the latest configuration word data can be downloaded from the configuration word cloud database, so that the real-time update of the vehicle configuration word at the user end is realized, which is convenient and efficient.

[0053] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent replacement or transformation made by those skilled in the art on the basis of the present application is within the protection scope of the present application.
