Description

Technical Field

[0001] The present application relates to the field of intelligent driving technology, and in particular to a grayscale release method for an intelligent driving function. Background Art

[0002] Currently in the smart driving scenario, "grayscale" means providing new functions only to a specific group of target users (such as technology enthusiasts or specific vehicle groups), allowing them to experience and test new functions first, while collecting usage feedback, optimizing function design based on the feedback, and gradually expanding the scope of application to ultimately achieve full promotion.

[0003] The grayscale release of intelligent driving functions mainly relies on FOTA (Firmware Over-The-Air) technology, which deploys new functions by remotely updating the domain controller software in the vehicle. However, the existing FOTA upgrade process is relatively cumbersome, and it often takes several weeks from the user submitting the experience application to the function activation. This not only reduces the iteration efficiency of the intelligent driving algorithm, but may also affect users' enthusiasm for the new function experience and even hinder the timeliness of user feedback. Summary of the invention

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] The following will describe in detail a grayscale release method for an intelligent driving function provided by an embodiment of the present application in conjunction with a specific implementation method. Figure 1 A flowchart of a grayscale release method of an intelligent driving function provided in an embodiment of the present application, such as Figure 1 As shown, the method is applied to the grayscale release platform, and the specific steps are as follows:

[0041] Step 101: Receive experience application information sent by an invited user.

[0042] In implementation, invited customers can query the experience information of newly released smart driving functions through http requests to the grayscale publishing platform in the car owner APP or other user terminals. After filling in the relevant information, the invited customers submit the experience application information containing the car owner ID, frame number and function identification information to the grayscale publishing platform. The grayscale publishing platform can receive the experience application information of the newly released smart driving functions through the car owner APP or other user terminals. For example: the invited user can fill in and submit the experience application information through the car owner APP, select the "Smart Cruise" function as a trial function, and the experience application information includes the user ID "U12345", frame number "V123456789", and function identification information "F123".

[0043] As an optional implementation, the experience application information includes the vehicle owner ID, vehicle frame number and function identification information.

[0044] Step 102: Generate a function activation certificate based on the experience application information.

[0045] In implementation, the function activation certificate is the key credential for activating new functions, ensuring the security and uniqueness of vehicle function activation. The Grayscale Release Platform generates a function activation certificate based on the experience application information, which contains function identification information, vehicle identification information, certificate validity period, and digital signature information to prevent tampering. For example: The Grayscale Release Platform generates a function activation certificate containing the following content: Function identification: F123, vehicle identification: V12345, certificate validity period: 30 days (20XX-XX-01 to 20XX-XX-31), digital signature: SHA256 signature encryption.

[0046] As an optional implementation, the function activation certificate includes function identification information, vehicle identification information, certificate validity period and digital signature information.

[0047] Step 103: Send a function activation notification to the vehicle-side intelligent driving domain controller.

[0048] In implementation, the grayscale publishing platform can send a function pending activation notification through the MQTT protocol, and the vehicle-side intelligent driving domain controller will be informed of the new function that needs to be activated. This step is only a notification and does not include a function activation certificate, which can effectively reduce the communication load and enhance the reliability of the control step. For example: The grayscale publishing platform sends a function pending activation notification to the vehicle-side intelligent driving domain controller: "The function 'Smart Cruise' you applied for is pending activation."

[0049] Step 104, after receiving the function activation query request from the vehicle-side intelligent driving domain controller, verify the software version of the vehicle-side intelligent driving domain controller. If the software version meets the preset upgrade requirements, return the function activation certificate.

[0050] In implementation, the grayscale release platform verifies the software version to ensure that the software version of the vehicle-side intelligent driving domain controller is compatible with the new function. If the software version meets the preset upgrade requirements, the function activation certificate is returned to the vehicle-side intelligent driving domain controller. For example: The grayscale release platform initiates a query request for the software version of the vehicle-side intelligent driving domain controller, and the version number is "1.0". If the grayscale release platform verifies that the supported version is "1.0 and above", the software version meets the preset upgrade requirements, returns the activation certificate and records the log.

[0051] Step 105: Receive function activation callback information from the vehicle-side intelligent driving domain controller and update the grayscale release status.

[0052] In implementation, the grayscale release platform confirms the completion of the function activation of the vehicle-side intelligent driving domain controller through callback information, updates the platform status, and provides for subsequent statistical analysis and management. For example, the callback information of the vehicle-side intelligent driving domain controller is: "Function 'Intelligent Cruise' is activated successfully, activation time 20XX-XX-XX." The grayscale release platform records the status of the vehicle-side intelligent driving domain controller for the new function as "activation completed".

[0053] As an optional implementation, the gray release platform is also used to maintain vehicle models, function identification information of new functions, new function names, new function descriptions, function experience validity periods, and software versions supported by the functions.

[0054] In implementation, the grayscale release platform maintains information related to vehicle models and new functions. The main purpose is to comprehensively manage grayscale releases and provide precise support for the release of different vehicles and functions. By maintaining key information (such as vehicle models, new function names, and new function descriptions, etc.), it is possible to push supported new functions in a targeted manner based on the vehicle model and software version to avoid compatibility issues or erroneous pushes. The functional identification information, name, and description of new functions are easy to store, retrieve, and manage within the platform, providing a clear functional classification. By setting the validity period of the function experience, the grayscale release platform can accurately control the time window for the trial of new functions to ensure the orderliness of the trial. The grayscale release platform maintains the software version supported by the new function to ensure that the function is only pushed to vehicles that meet the requirements, improving system stability and user experience.

[0055] As an optional implementation, if the software version of the vehicle-side intelligent driving domain controller is lower than the software version supported by the function, it is determined that the software version does not meet the preset upgrade requirements, and an upgrade prompt message is sent to the invited user;

[0056] If the software version of the vehicle-side intelligent driving domain controller is higher than or at the software version supported by the function, it is determined that the software version meets the upgrade requirements.

[0057] In implementation, during the grayscale release process, by verifying the software version of the vehicle-side intelligent driving domain controller, it is ensured that the new function is activated only when the version requirements are met, thereby avoiding the situation where the new function is unavailable or the system is unstable due to the software version being too low. Specifically, after receiving the function activation query request from the vehicle, the grayscale release platform can verify the software version of the vehicle-side intelligent driving domain controller. If the software version is lower than the software version supported by the function, the function cannot be activated, and the platform sends an upgrade prompt message to the invited user. If the software version is higher than or equal to the software version supported by the function, the function meets the activation conditions, and the platform continues the subsequent activation process. When the software version is not met, an upgrade prompt message can be sent to the user to guide the user to upgrade the software version of the vehicle-side intelligent driving domain controller through FOTA, reducing the possibility of users being confused by version incompatibility. For example: the software version supported by the new function is 1.2 and above. The grayscale release platform verifies that the software version of the vehicle-side intelligent driving domain controller is 1.0, which is lower than the software version supported by the new function. The grayscale release platform can send upgrade prompts to invited users. At the same time, the grayscale release platform can record version verification failure logs for subsequent analysis and feedback optimization. For example, the grayscale release platform verifies that the vehicle-side intelligent driving domain controller software version is 1.2, which meets the software version requirements for new functions. The grayscale release platform returns the function activation certificate to the vehicle-side intelligent driving domain controller to support users to activate the function normally.

[0058] Another method for grayscale release of an intelligent driving function provided in an embodiment of the present application is described in detail. Figure 2 A flowchart of another method for grayscale release of an intelligent driving function provided in an embodiment of the present application, such as Figure 2 As shown, the method is applied to the vehicle-side intelligent driving domain controller, and the specific steps are as follows:

[0059] Step 201, receiving a function activation notification sent by a grayscale publishing platform.

[0060] During implementation, the vehicle-side intelligent driving domain controller can receive function activation notifications sent by the grayscale publishing platform through the MQTT protocol.

[0061] Step 202: Send a function activation query request to the grayscale publishing platform.

[0062] In implementation, the vehicle-side intelligent driving domain controller can be accompanied by information such as the vehicle frame number and the software version of the vehicle-side intelligent driving domain controller, and query the grayscale release platform through HTTP requests whether there are new functions to be activated:

[0063] As an optional implementation, the function activation query request includes vehicle identification information and software version.

[0064] Step 203: Receive the function activation certificate returned by the grayscale publishing platform, and activate the intelligent driving function corresponding to the function activation certificate.

[0065] In implementation, the vehicle-side intelligent driving domain controller can verify the authenticity and content of the function activation certificate, and then complete the activation of the new function based on the function activation certificate, and record the certificate validity period for subsequent management. For example: the vehicle-side intelligent driving domain controller can complete the activation of the "smart cruise" function through the function activation certificate and set the validity period to 30 days.

[0066] Step 204: Send function activation callback information to the grayscale publishing platform.

[0067] In implementation, the vehicle-side intelligent driving domain controller can feedback the function activation status to the grayscale release platform so that the grayscale release platform can update the grayscale release data according to the callback information. For example: the vehicle-side intelligent driving domain controller can send a function activation callback message to the grayscale release platform: "Function F123 is activated successfully, valid from 20XX-XX-01 to 20XX-XX-31."

[0068] Step 205 , verifying the validity period of the function activation certificate each time the vehicle is started, and if the function activation certificate expires, terminating the function activation state of the intelligent driving function.

[0069] In practice, function validity management can be achieved through the validity period verification of the function activation certificate to ensure that the function trial is limited to the specified time and avoid function abuse or expired use. For example: when the vehicle is started, if the vehicle-side intelligent driving domain controller verifies that the certificate validity period of the function activation certificate has expired, the "intelligent cruise" function will be automatically turned off.

[0070] As an optional implementation, the vehicle-side intelligent driving domain controller is also used to receive a software version upgrade instruction sent by an invited user;

[0071] Update the software version of the vehicle-side intelligent driving domain controller.

[0072] In implementation, the vehicle-side intelligent driving domain controller can receive software version upgrade instructions sent by invited users and update its software version functions, mainly to ensure that the vehicle can run the latest and compatible new functions, while optimizing the user's operating procedures. For example: invited users can actively send upgrade instructions to the vehicle-side intelligent driving domain controller through terminals such as the owner's APP. The vehicle-side intelligent driving domain controller completes the software upgrade through FOTA technology. The FOTA mechanism pushes the upgrade package to the vehicle through the network, and the vehicle-side intelligent driving domain controller completes the unpacking, verification and installation. After the upgrade is successful, the vehicle-side intelligent driving domain controller can send status feedback information to the grayscale release platform, for example: the upgrade status is successful, and the current software version is 1.2. If the upgrade fails, the vehicle-side intelligent driving domain controller can record the reason for the failure and notify the invited user to try the upgrade again.

[0073] As an optional implementation, the specific method for updating the software version of the vehicle-side intelligent driving domain controller is to upgrade the software version of the vehicle-side intelligent driving domain controller through FOTA technology.

[0074] As an optional implementation, the vehicle-side intelligent driving domain controller is also used to send function activation status information to invited users.

[0075] During implementation, the grayscale release platform can call the car owner APP to send a message interface with the car owner ID, function identification information of the new function, function validity period and other information to notify the invited user that the new function has been activated.

[0076] The embodiment of the present application provides a grayscale release method for an intelligent driving function. On the one hand, it is applied to a grayscale release platform, and the method includes: receiving experience application information sent by an invited user. Generate a function activation certificate according to the experience application information. Send a function to-be-activated notification to the vehicle-side intelligent driving domain controller. After receiving a function activation query request from the vehicle-side intelligent driving domain controller, verify the software version of the vehicle-side intelligent driving domain controller. If the software version meets the preset upgrade requirements, return the function activation certificate. Receive the function activation callback information of the vehicle-side intelligent driving domain controller, and update the grayscale release status. On the other hand, it is applied to the vehicle-side intelligent driving domain controller, and the method includes: receiving a function to-be-activated notification sent by a grayscale release platform. Send a function activation query request to the grayscale release platform. Receive the function activation certificate returned by the grayscale release platform, and activate the intelligent driving function corresponding to the function activation certificate. Send function activation callback information to the grayscale release platform. Verify the certificate validity period of the function activation certificate each time the vehicle is started. If the function activation certificate expires, the function activation state of the intelligent driving function is terminated. The embodiment of the present application uses digital signatures and function activation certificates to ensure the security of the function activation process and avoid illegal activation or data tampering. Through the interaction between the car owner APP and the grayscale release platform, invited users can view the function status and related notifications in real time, enhancing the convenience of trial. The vehicle automatically detects the activation status of the function and the validity period of the certificate without manual intervention by the user, simplifying the use process. The grayscale release platform can update the status and trial data in real time, providing support for subsequent statistical analysis, new function development and large-scale promotion.
