DETAILED DESCRIPTION

[0060] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments made by ordinary technicians in this field based on the inspiration of these embodiments fall within the scope of protection of this application.

[0061] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the numbers used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0062] First, let’s explain the terms involved in this application:

[0063] Telematics BOX (T-BOX) is an in-vehicle communication device that connects to the backend TSP platform via the network. It allows users to obtain information such as the vehicle's operating status and synchronizes in-vehicle data with the backend system.

[0064] In the existing technology, after downloading the software through the OTA server, it is directly installed on the vehicle side, which poses the risk of the vehicle being attacked by hackers and makes it difficult to ensure the security of vehicle information. To solve the above problems, the concept of this application is to ensure that the vehicle can safely download software and ensure the legality of the software to be downloaded.

[0065] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0066] Figure 1 This is a flow chart of a first embodiment of a method for processing vehicle-based application functions provided by this application, as shown in FIG. Figure 1 As shown, this method can be applied in the scenario of vehicle downloading software. Specifically, the method includes the following steps:

[0067] Step S101: Send a download request for the application function to the cloud server, where the application function download request includes the vehicle identifier and the identifier of the application function to be downloaded, so that the cloud server obtains the vehicle information corresponding to the vehicle identifier and the function information corresponding to the identifier of the application function to be downloaded according to the download request, and sends the vehicle information and function information to the OTA server.

[0068] In this embodiment, the cloud server includes an OTA server and a telematics service provider (TSP). After the OTA receives the download request, the TSP activates the software function. The identification of the application function to be downloaded includes all vehicle configuration data (VCD) collected by the OTA server, and the vehicle information includes the vehicle identification number (VIN).

[0069] Step S102: Obtain the inspection instruction carrying vehicle information and function information issued by the OTA server, and according to the inspection instruction, obtain the current vehicle configuration code value and the first download information corresponding value corresponding to the current vehicle configuration code value, and perform inspection processing based on the current vehicle configuration code value and the first download information corresponding value to obtain a first verification result.

[0070] In this embodiment, the OTA server sends a verification instruction containing vehicle information and function information to the T-BOX controller. The T-BOX controller sends this instruction to the body controller through the gateway controller. The body controller generates a first download message corresponding value (BuyMessage Fxxx; abbreviated as: BMF) corresponding to the current vehicle configuration code value (Car Config; abbreviated as: CC) based on the current CC value, and sends the current CC value and the first BMF to other controllers in the car. Other controllers perform verification based on the current CC value and the first BMF.

[0071] Step S103: When the first verification result is successful, the function information is downloaded and installed on the car through the OTA server software upgrade strategy, and the current CC value is upgraded to obtain the updated CC value and the second download information corresponding value corresponding to the updated CC value.

[0072] In this embodiment, when the OTA server receives the first verification success, the body controller updates the CC value based on the downloaded software, obtains the updated CC value, and generates a second download information corresponding value corresponding to the updated CC value based on the updated CC value, where the second download information corresponding value is the second BMF.

[0073] If the OTA server receives a first verification result indicating a failure, it will re-notify the TSP to activate the purchased software function. If the verification cycle fails three times, the user will be notified of the function activation failure, which may be a notification message indicating that the vehicle does not support the software function.

[0074] Step S104: performing verification processing according to the updated CC value and the second BMF to obtain a second verification result, and generating a download success response message when the second verification result is verification success.

[0075] In this embodiment, the vehicle body controller sends the updated CC value and the second BMF to other controllers, and the other controllers perform secondary verification based on the updated CC value and the second BMF to ensure the correctness of the software installation path.

[0076] If the OTA server receives a second verification result indicating a verification failure, it will re-notify the TSP to activate the purchased software function. If the verification cycle fails three times, the user will be notified that the function activation failed or was abnormal.

[0077] In this embodiment, the T-BOX controller, vehicle gateway controller, and body controller are connected to the vehicle's CAN, Ethernet, and FlexRay networks, and information is exchanged with the vehicle through the microcontroller unit (MCU) inside each controller via CAN, Ethernet, FlexRay, and other transceivers.

[0078] In this embodiment, by constructing a two-time verification mechanism, other controllers verify the current CC value and the first BMF corresponding to the current CC value, as well as the updated CC value and the second BMF corresponding to the updated CC value. Compared with the prior art of directly installing the downloaded software, this application improves the guarantee of the matching between the vehicle and the required downloaded software, the legitimacy of the in-vehicle controller, the legitimacy of the required downloaded software, and the correctness of the software installation path.

[0079] Figure 2 This is a signaling diagram of a second embodiment of a processing method based on a vehicle application function provided by this application, such as Figure 2 As shown, the method includes the following steps:

[0080] Step S201: The terminal device sends a download request for the application function to the OTA server in the cloud server. The application function download request includes the vehicle identifier and the identifier of the application function to be downloaded, so that the OTA server in the cloud server obtains the vehicle information corresponding to the vehicle identifier and the function information corresponding to the identifier of the application function to be downloaded according to the download request, and sends the vehicle information and function information to the OTA server.

[0081] In this embodiment, the cloud server includes an OTA server.

[0082] Step S202: The OTA server sends a test instruction carrying vehicle information and function information to the T-BOX controller.

[0083] Step S203: The T-BOX controller triggers the vehicle's gateway controller.

[0084] Step S204: The gateway controller downloads the inspection instruction carrying the vehicle information and function information from the T-BOX controller, wakes up the body controller, and sends the inspection instruction carrying the vehicle information and function information to the body controller.

[0085] Step S205: The vehicle body controller obtains the current CC value and the first BMF corresponding to the current CC value according to the inspection instruction, and sends the current CC value and the first BMF to other controllers except the vehicle body controller.

[0086] Step S206: Each of the other controllers verifies the legitimacy of the vehicle and function information, as well as the legitimacy of the controller, based on the current CC value and the first BMF, and generates a first verification result indicating success. This first verification result is then sent to the OTA server via the T-BOX controller. If the first verification result indicates success, a first verification result indicating success is generated and step S207 is executed. If the first verification result indicates failure, the OTA server reissues a verification instruction containing the vehicle and function information via the T-BOX controller and the gateway controller to the body controller. The other controllers repeat the first verification. If the verification fails three times, step S210 is executed.

[0087] Step S207: The vehicle body controller downloads and installs the software function information and upgrades the current CC value to obtain an updated CC value and a second BMF corresponding to the updated CC value. The updated CC value and the second BMF corresponding to the updated CC value are sent to other controllers.

[0088] Step S208: Each of the other controllers verifies the legitimacy of the vehicle information and function information, as well as the legitimacy of the controller, based on the updated CC value and the second BMF, and sends the second verification result to the OTA server via the T-BOX controller. If the second verification result is a successful verification, a second verification result of successful verification is generated, and step S209 is executed. If the second verification result is a failed verification, the OTA server re-issues the inspection instruction carrying the vehicle information and function information via the T-BOX controller and the gateway controller to the body controller, and repeats the second verification. If the verification cycle fails three times, step S210 is executed.

[0089] Step S209: The OTA server generates a download success response message and sends the download success response message to the terminal device.

[0090] Step S210: The OTA server generates a notification message indicating that the vehicle does not support the software function information, and sends the notification message indicating that the vehicle does not support the software function information to the terminal device.

[0091] Specifically, such as Figure 3 The purchase process diagram provided in this application is shown. The user sends a request to purchase or subscribe to application functions, i.e., software, to the OTA server through the function mall based on the terminal device, and carries the vehicle information for downloading the application functions, wherein the terminal device can be a mobile phone or a car machine, and has a built-in virtual network device and a timer, and the user can set the waiting time for downloading. The OTA server collects vehicle configuration data, vehicle information, and waiting time for downloading, and sends the vehicle configuration data, vehicle information, and waiting time for downloading to the TSP; the TSP activates the function of the vehicle configuration data and wakes up the T-BOX controller; the T-BOX controller sends a wake-up signal to the gateway controller, and sends the vehicle configuration data, vehicle information, and waiting time for downloading to the gateway controller; the gateway controller sends a wake-up signal to the body controller, and the body controller sends status feedback to the gateway controller based on the current status. The gateway controller obtains the diagnostic instruction based on the status feedback and sends the diagnostic instruction to the body controller. When the body controller makes positive feedback, it performs a reset, and generates a new CC value and the first BMF corresponding to the current CC value based on the vehicle configuration data and vehicle information, and The current CC value and the first BMF are sent to other controllers except the body controller, so that each of the other controllers verifies the legitimacy of the vehicle information and function information, as well as the legitimacy of the controller, based on the current CC value and the first BMF. When the first verification result is successful, the function information is downloaded and installed, and the current CC value is upgraded to obtain an updated CC value and a second BMF corresponding to the updated CC value. The updated CC value and the second BMF are sent to the other controllers, so that each of the other controllers verifies the legitimacy of the vehicle information and function information, as well as the legitimacy of the controller, based on the updated CC value and the second BMF, and verifies the accuracy of the installation addresses of the other controllers. The body controller sends the two verification results to the gateway controller; the gateway controller feeds back the two verification results to the T-BOX controller; the T-BOX controller sends the verification results to the TSP, and the TSP sends the verification results to the OTA server. If the verification result is successful, a message indicating successful function activation is sent to the terminal device and the timer starts. The terminal device prompts the user that the function has been activated. If the verification result is failed, the OTA server re-sends the function activation instruction to the TSP based on the vehicle configuration data, vehicle information and waiting download time, and repeats the verification. If the cycle fails three times, a message indicating that function activation failed is sent to the terminal device, and the terminal device prompts the user that the function activation is abnormal.

[0092] In this embodiment, the T-BOX controller, vehicle gateway controller, and body controller are connected to the vehicle's CAN, Ethernet, and FlexRay networks, and information is exchanged with the vehicle through the microcontroller unit (MCU) inside each controller via CAN, Ethernet, FlexRay, and other transceivers.

[0093] In this embodiment, by constructing a two-time verification mechanism, other controllers verify the current CC value and the first BMF corresponding to the current CC value, as well as the updated CC value and the second BMF corresponding to the updated CC value. Compared with the prior art of directly installing the downloaded software, this application improves the guarantee of the matching between the vehicle and the required downloaded software, the legitimacy of the in-vehicle controller, the legitimacy of the required downloaded software, and the correctness of the software installation path.

[0094] Figure 4 A schematic diagram of a processing system based on vehicle application functions provided in this application, such as Figure 4As shown, the user logs in to the mall through the terminal device and sends a download request for the application function to the cloud server. The application function download request includes the vehicle identification and the identification of the application function to be downloaded. The terminal device can be a mobile phone or a car computer. The OTA server in the cloud server collects all vehicle configuration data and sends the vehicle information corresponding to the vehicle identification and the function information corresponding to the identification of the application function to be downloaded to the TSP. The TSP activates the application function, that is, the software, wakes up the T-BOX controller, and issues a test instruction carrying the vehicle information and function information; the T-BOX controller is connected to the gateway controller, the gateway controller is connected to the body controller and other controllers, and the T-BOX controller receives the test instruction carrying the vehicle information and function information After the verification instruction is sent, the verification instruction carrying the vehicle information and function information is sent to the gateway controller. The gateway controller sends the verification instruction carrying the vehicle information and function information to the body controller. The body controller obtains the current CC value and the first BMF corresponding to the current CC value. The body controller sends the current CC value and the first BMF to other controllers. The other controllers verify according to the current CC value and the first BMF to obtain a first verification result, and send the first verification result to the gateway controller. The gateway controller sends the first verification result to the T-BOX controller. The T-BOX controller sends the first verification result to the OTA server. If the first verification result is a failure, the vehicle information corresponding to the vehicle identifier and the application to be downloaded are sent to the OTA server. The function information corresponding to the function identifier is sent to the TSP, and the TSP activates the application function, i.e., the software, again. If the cycle fails three times, a notification message of function activation failure or exception is sent to the end user, specifically, a notification message that the vehicle does not support the software function information; if the first verification result is successful, the body controller downloads and installs the function information, and sends a download success message to the OTA server through the gateway controller and the T-BOX controller, upgrades the current CC value to obtain the updated CC value and the second BMF corresponding to the updated CC value, and sends the updated CC value and the second BMF to other controllers. The other controllers perform verification processing based on the updated CC value and the second BMF to obtain the second verification result. The second verification result is sent to the gateway controller, the gateway controller sends the second verification result to the T-BOX controller, the T-BOX controller sends the second verification result to the OTA server. If the second verification result is a failure, the vehicle information corresponding to the vehicle identifier and the function information corresponding to the identifier of the application function to be downloaded are sent to the TSP. The TSP activates the application function, i.e., the software, again. If it still fails after three cycles, a notification message of function activation failure or abnormality is sent to the terminal device, which may be a notification message that the vehicle does not support the software function information; if the second verification result is a success, a download success response message is generated and sent to the OTA server via the gateway controller T-BOX controller. The OTA server sends the download success response message to the terminal device.

[0095] Among them, the T-BOX controller, gateway controller, and body controller are connected to the vehicle's CAN, Ethernet, and FlexRay networks, and the MCU inside each controller exchanges information with the entire vehicle through CAN, Ethernet, FlexRay and other transceivers.

[0096] In this embodiment, by constructing a two-time verification mechanism, other controllers verify the current CC value and the first BMF corresponding to the current CC value, as well as the updated CC value and the second BMF corresponding to the updated CC value. Compared with the prior art of directly installing the downloaded software, this application improves the guarantee of the matching between the vehicle and the required downloaded software, the legitimacy of the in-vehicle controller, the legitimacy of the required downloaded software, and the correctness of the software installation path.
