[0055] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein.

[0056] The embodiment of the present application is applicable to the stage from vehicle offline to pre-delivery, through offline autonomous code scanning in stores, autonomous control of upgrades and upgrade status monitoring, to prevent the delivery of unupgraded vehicles. The method provided in the embodiment of the present application can be executed by an OTA upgrade handheld device, and the following description takes the OTA upgrade handheld device as the execution subject as an example.

[0057] See also Figure 1 An embodiment of the present application provides an OTA upgrade method, including:

[0058] Step 110: Displaying multiple objects on a first display interface;

[0059] See also Figure 2 , which is a schematic diagram of the first display interface. The first display interface is generated before the handheld OTA upgrade tool starts the OTA upgrade preparation. The first display interface displays multiple objects, and the vehicle identification code of the target vehicle can be obtained in response to the user's operation.

[0060] Step 120: Responding to the user's input operation on the first object or the scanning operation on the second object, obtaining a target vehicle identification code, and sending the target vehicle identification code to the OTA upgrade platform, so that the OTA upgrade platform returns corresponding current software version data according to the target vehicle identification code;

[0061] In an embodiment of the present invention, a user can input a target vehicle identification code through a first object on a first display interface, or scan a target vehicle frame number signal through a second object to obtain a target vehicle identification code, and send the target vehicle identification code to an OTA upgrade platform, so that the OTA upgrade platform returns the target vehicle identification code to the current software version data.

[0062] Step 130: When it is determined that an OTA upgrade is required according to the current software version data and the upgradeable software version data, in response to an OTA upgrade request generated by the user touching the third object, a second display interface is generated;

[0063] In an embodiment of the present invention, the upgradeable software version data is the upgradeable software version data formed by the backstage personnel selecting each controller to the target version according to the target vehicle version. The embodiment of the present invention compares the current software version data with the upgradeable software version data, and determines the need for OTA upgrade based on the comparison result. The first display interface can also display whether the current software version data is the latest version. If it is the latest software version, it will be displayed that the vehicle can be delivered. If it is not the latest version, it will be displayed as the vehicle needs to be upgraded through the third object, and the second display interface is generated by responding to the OTA upgrade request generated by the user touching the third object.

[0064] See also Figure 3 , is a schematic diagram of a second display interface provided in an embodiment of the present invention, the second display interface displays multiple objects for the user to select an upgrade task and confirm to add the selected upgrade task.

[0065] Step 140: In response to the OTA upgrade task selected by the user according to the second display interface, the OTA upgrade task is sent to the OTA upgrade platform, and the OTA upgrade is performed through the OTA upgrade platform.

[0066] In an embodiment of the present invention, the user can select an OTA upgrade task to perform an OTA upgrade according to the selection object on the second display interface. After the vehicle OTA upgrade is completed, the OTA upgrade platform automatically triggers a text message reminder mechanism and pushes a reminder text message to the client of each relevant store staff to inform the store staff that the vehicle upgrade is successful, so that the vehicle can be delivered in time.

[0067] In an embodiment of the present invention, the target vehicle identification code can be quickly and conveniently obtained by scanning or inputting the target vehicle identification code through the OTA upgrade handheld device. When it is determined that OTA upgrade is required based on the current software version data and the upgradeable software version data, the OTA upgrade task can be selected and the upgrade can be performed through the generated second display interface. The OTA upgrade can be quickly implemented through the OTA upgrade handheld device, and there is no need to log in to the store-specific account to perform OTA upgrade on the vehicle, which effectively simplifies the OTA upgrade process, thereby effectively improving the OTA upgrade efficiency.

[0068] In an optional manner, the second interface includes a plurality of upgrade task selection objects, and the response to the OTA upgrade task selected by the user according to the second display interface includes:

[0069] In response to the user's selection operation on the upgrade task selection object, the OTA upgrade task selected by the user is determined.

[0070] In an embodiment of the present invention, the second display interface includes an object that displays the current vehicle identification code. The upgrade task selection object may include multiple upgrade tasks, including upgrade tasks corresponding to the lowest version to the latest version, where the default is to automatically select the latest version. The user can select any upgrade task for upgrade through the selection operation, that is, not only can the latest task be selected, but also the previous version can be rolled back for upgrade.

[0071] The embodiment of the present invention provides a plurality of upgrade task selection objects through the second display interface, so that the upgrade can be performed in response to any OTA upgrade task selected by the user, which can effectively improve the flexibility of the OTA upgrade.

[0072] In an optional manner, after sending the OTA upgrade task to the OTA upgrade platform for OTA upgrade, the method further includes:

[0073] Receive the upgrade status information returned by the OTA upgrade platform;

[0074] In the embodiment of the present invention, the upgrade status information includes upgrading, successful upgrading, failed upgrading, pending processing and downloading.

[0075] Displaying a third display interface, wherein the third display interface includes a fourth object, a fifth object, and an upgrade status display list;

[0076] See also Figure 4 , is a schematic diagram of a third display interface provided in an embodiment of the present invention. The third display interface displays multiple objects for the user to filter different upgrade states according to actual needs, and displays the corresponding vehicle identification code.

[0077] In response to a vehicle identification code query instruction input by the user according to the fourth object, the queried vehicle identification code and corresponding upgrade status information are displayed in the upgrade status list;

[0078] In response to the upgrade status filtering instruction selected by the user according to the fifth object, the filtered upgrade status information and the corresponding vehicle identification code are displayed in the upgrade status display list.

[0079] In the embodiment of the present invention, the current upgrade status information and the corresponding vehicle identification code can be found by inputting the fourth object or selecting the fifth object, so that the upgrade progress can be accurately viewed through the third display object, effectively improving the OTA upgrade efficiency.

[0080] In an optional manner, the OTA upgrade method further includes:

[0081] The OTA upgrade platform performs shared object encryption on the software version data collected by TBOX to obtain a software package, and obtains upgradeable software version data based on the software package.

[0082] In the embodiment of the present application, the software data collected by TBOX can be the latest software version data, which is uploaded to the software warehouse platform, and encrypted by adding a shared object file to the software data through the software warehouse platform to obtain the corresponding software package, which is synchronized to the OTA upgrade platform, and the software package is preprocessed by the OTA upgrade platform to obtain the upgradeable software version data. The preprocessing includes initialization, packaging, encryption and signature upload, and the creation of the upgradeable software version data is completed after the upload is successful.

[0083] The embodiment of the present application obtains a software package by encrypting a shared object file, and encapsulates the collected software version data into a shared object, which effectively prevents unauthorized access and tampering. It not only ensures the security of the software version data during transmission and storage, but also ensures the correctness of the upgradeable software version data, thereby improving the efficiency of vehicle OTA upgrades.

[0084] Furthermore, encapsulating the collected software version data into a shared object and communicating with the OTA upgrade platform through a single object can reduce the complexity of communication and the amount of data required for transmission, effectively simplifying the communication process, thereby further improving the efficiency of vehicle OTA upgrades.

[0085] In an optional manner, determining that an OTA upgrade is required according to current software version data and upgradeable software version data includes:

[0086] The current software version data is compared with the upgradeable software version data, and based on the comparison results, it is determined that the target vehicle requires OTA upgrade.

[0087] In an embodiment of the present application, the upgradeable software version data is the latest version data. The current software version data is compared with the upgradeable software version data. If the current software version data is inconsistent with the upgradeable software version data, it is determined that the current software version is not the latest version. The controller corresponding to the current software version is an upgradeable controller. At this time, it is determined that the target vehicle needs to be upgraded by OTA.

[0088] The embodiment of the present invention compares the current software version data with the upgradeable software version data, and determines that the target vehicle needs OTA upgrade based on the comparison result. It can accurately determine whether the current software version data needs to be upgraded, and avoid OTA upgrade when the current software version data is the latest software version data, thereby effectively improving the OTA upgrade efficiency.

[0089] In an optional manner, the OTA upgrade is performed through the OTA upgrade platform, including:

[0090] Download the software of the controller to be upgraded according to the OTA upgrade task;

[0091] Determining that the target vehicle meets a preset upgrade condition, and performing OTA upgrade on the software of the controller to be upgraded;

[0092] Among them, the preset upgrade conditions include that the power value is within a preset threshold range, the gear is in P gear, the network connection status is normal, and the charging gun is not connected.

[0093] In an embodiment of the present application, before the upgrade, it is determined whether the target vehicle meets the preset upgrade conditions, including that the power value is within the preset threshold range, the gear is in P gear, the network connection status is normal, and the charging gun is not connected, etc., to ensure that the target vehicle can successfully complete the OTA upgrade task.

[0094] For example, the OTA upgrade process requires a certain amount of power to download software versions and upgrades. Before performing the OTA upgrade, it is necessary to ensure that the vehicle's power is within the preset threshold range, where the preset threshold range can be designed as needed. For example, the preset threshold range can be set to 5%-100%, 10%-100% or 15%-100%, etc.

[0095] For example, ensuring that the current gear is in P gear can effectively reduce interference caused by unexpected movement of the target vehicle during the upgrade process and ensure that the OTA upgrade process can be executed normally.

[0096] For example, before starting an OTA upgrade, a network stability check is automatically performed to ensure that the current network connection status is normal, so as to ensure that the wireless connection is stable enough to avoid data loss or errors caused by network instability during the upgrade process.

[0097] For example, to avoid possible interference with the vehicle's electronic system during the charging process and to ensure that the upgrade process is not affected by external electrical influences, it is necessary to ensure that the charging gun is not connected.

[0098] After determining that the target vehicle meets the preset upgrade conditions, the embodiment of the present application automatically performs a silent upgrade on the vehicle without the need for personnel to perform click operations on the vehicle computer, which can effectively improve the efficiency of the vehicle OTA upgrade.

[0099] The embodiment of the present application uses the preset threshold range, the gear position is P gear, the network connection status is normal and the charging gun is not connected as the conditions for judging whether the target vehicle meets the preset upgrade conditions, thereby avoiding the risk of interruption of the target vehicle during the OTA upgrade process, reducing interference or damage caused by accidental movement during the upgrade process, and avoiding possible interference to the vehicle's electronic system during the charging process, ensuring that the upgrade process is not affected by external electrical factors, thereby effectively improving the efficiency and safety of the vehicle's OTA upgrade.

[0100] In an embodiment of the present invention, the software of the controller to be upgraded is downloaded according to the OTA upgrade task, and there is no need to download the version data of the controller whose software version data is the latest. When performing OTA upgrade, only the software-upgradeable controller needs to be OTA upgraded. For example, the controller of the target vehicle includes various controllers such as the engine control unit (ECU), the vehicle infotainment system, and the advanced driver assistance system (ADAS). If the version of the ECU is not the latest version, and the versions of the vehicle infotainment system and the advanced driver assistance system are the latest versions, only the corresponding version data is downloaded and OTA upgraded for the ECU, and the version download and upgrade of the vehicle infotainment system and the advanced driver assistance system are skipped. This can effectively reduce the repeated download and upgrade of software version data, thereby effectively improving the efficiency of vehicle OTA upgrades.

[0101] In an optional manner, the OTA upgrade is performed through the OTA upgrade platform, including:

[0102] Download the software of the controller to be upgraded according to the OTA upgrade task;

[0103] Determining that the software of the controller to be upgraded meets a preset upgrade requirement, and performing OTA upgrade on the software of the controller to be upgraded;

[0104] The preset upgrade requirements include one or more combinations of the following: software serial number, controller name and logical address.

[0105] In the embodiment of the present invention, the software serial number is the version number or serial number of the software, which can be used to identify different software versions. The software serial number includes the major version number, minor version number, revision number and build number, etc. The controller name is the controller name corresponding to the software to be upgraded; the logical address is the location in the computer system where the software is loaded into the memory.

[0106] The embodiment of the present application verifies the software serial number, controller name and logical address, and automatically enters the OTA upgrade when at least one of the three pieces of information is consistent with the target software to be upgraded. If all three pieces of information are verified to be wrong, the OTA upgrade platform automatically reports an error and stops the OTA upgrade task, ensuring that the correct software version data can be upgraded, thereby improving the accuracy and reliability of vehicle OTA upgrades.

[0107] In an optional manner, before performing OTA upgrade through the OTA upgrade platform, the following is also included:

[0108] The sales status of the target vehicle is determined to be sold.

[0109] In the embodiment of the present application, it is possible to determine whether the target vehicle has been sold by verifying the vehicle sales status recorded in the vehicle management system. If the vehicle is in the sold state, OTA upgrade cannot be performed, and there is no need to download the corresponding software version data and subsequent upgrade actions. If the vehicle is not sold, OTA upgrade can be performed, and the corresponding software version data is downloaded.

[0110] The embodiment of the present application verifies the sales status of the target vehicle and determines whether to download the corresponding software version data of the upgradeable first controller based on the vehicle sales status, thereby avoiding initiating download and upgrade tasks for vehicles that have already been sold, thereby effectively improving the efficiency of vehicle OTA upgrades.

[0111] In one embodiment, Figure 5 Another schematic diagram of the process of an OTA upgrade method according to an embodiment of the present invention is shown. Figure 5 The OTA upgrade methods shown include:

[0112] Step 510: Scan the target vehicle identification code, obtain the current software version data of the target vehicle, and compare the current software version data with the upgradeable software version data;

[0113] Step 520: Determine whether OTA upgrade is required, if not, go to step 530, if yes, go to step 540;

[0114] Step 530: Displaying a reminder that no upgrade is required through a display interface;

[0115] Step 540: Select an upgrade task and upload the target vehicle identification code;

[0116] Step 550: Automatically add the vehicle information to the designated upgrade task of the OTA upgrade platform, so that the vehicle automatically performs OTA upgrade;

[0117] Step 560: The OTA upgrade platform synchronizes the real-time progress of the upgrade to the front-end upgrade processing personnel;

[0118] In the embodiment of the present invention, the upgrade processing personnel can monitor the upgrade progress and status according to the synchronized real-time progress of the upgrade, and receive upgrade failure reminder information when the upgrade fails, so as to handle the upgrade failure problem in time.

[0119] Step 570: After the upgrade is successful, an upgrade success message is generated and a prompt is given that the vehicle can be delivered.

[0120] The implementation of the embodiments of the present invention has the following beneficial effects:

[0121] The embodiment of the present invention can quickly and conveniently obtain the target vehicle identification code by scanning or inputting the target vehicle identification code through the OTA upgrade handheld device. When it is determined that OTA upgrade is required based on the current software version data and the upgradeable software version data, the OTA upgrade task can be selected and the upgrade can be performed through the generated second display interface. The OTA upgrade can be quickly implemented through the OTA upgrade handheld device, and there is no need to log in to the store's dedicated account to perform OTA upgrade on the vehicle, which effectively simplifies the OTA upgrade process, thereby effectively improving the OTA upgrade efficiency.

[0122] Furthermore, the embodiment of the present invention downloads the software of the controller to be upgraded according to the OTA upgrade task, and there is no need to download the version data of the controller with the latest software version data. When performing an OTA upgrade, only the software-upgradeable controller needs to be OTA upgraded, which can effectively reduce the repeated downloading and upgrading of software version data, thereby effectively improving the efficiency of vehicle OTA upgrades.

[0123] Figure 6 Another flow chart of the OTA upgrade method of the present application is shown, including:

[0124] Step 610: receiving the target vehicle identification code sent by the OTA upgrade handheld device, querying and obtaining the current software version data of the target vehicle according to the target vehicle identification code, and returning the current software version data to the OTA upgrade handheld device;

[0125] In an embodiment of the present invention, a user can input a target vehicle identification code through a first object of a first display interface of an OTA upgrade handheld device, or scan a target vehicle frame number signal through a second object to obtain a target vehicle identification code, and send the target vehicle identification code to an OTA upgrade platform, so that the OTA upgrade platform returns the target vehicle identification code to the current software version data.

[0126] Step 620: When it is determined that an OTA upgrade is required based on the current software version data and the upgradeable software version data, respond to the OTA upgrade task sent by the OTA upgrade handheld device and perform an OTA upgrade on the target vehicle.

[0127] In the embodiment of the present invention, the upgradeable software version data is the upgradeable software version data formed by the back-end personnel selecting each controller to the target version according to the target vehicle version. The embodiment of the present invention compares the current software version data with the upgradeable software version data, and determines the need for OTA upgrade based on the comparison result.

[0128] The embodiment of the present invention determines that an OTA upgrade is required based on the current software version data and the upgradeable software version data, and responds to the OTA upgrade task sent by the OTA upgrade handheld device to perform an OTA upgrade on the target vehicle. This can accurately determine whether the current software version data needs to be upgraded, avoid upgrading when the current software version data is the latest software version data, and effectively improve the efficiency of the OTA upgrade.

[0129] In an optional manner, the OTA upgrade of the target vehicle includes:

[0130] Download the software of the controller to be upgraded according to the OTA upgrade task;

[0131] Determining that the target vehicle meets a preset upgrade condition, and performing OTA upgrade on the software of the controller to be upgraded;

[0132] Among them, the preset upgrade conditions include that the power value is within a preset threshold range, the gear is in P gear, the network connection status is normal, and the charging gun is not connected.

[0133] In an embodiment of the present application, before the upgrade, it is determined whether the target vehicle meets the preset upgrade conditions, including that the power value is within the preset threshold range, the gear is in P gear, the network connection status is normal, and the charging gun is not connected, etc., to ensure that the target vehicle can successfully complete the OTA upgrade task.

[0134] For example, the OTA upgrade process requires a certain amount of power to download software versions and upgrades. Before performing the OTA upgrade, it is necessary to ensure that the vehicle's power is within the preset threshold range, where the preset threshold range can be designed as needed. For example, the preset threshold range can be set to 5%-100%, 10%-100% or 15%-100%, etc.

[0135] For example, ensuring that the current gear is in P gear can effectively reduce interference caused by unexpected movement of the target vehicle during the upgrade process and ensure that the OTA upgrade process can be executed normally.

[0136] For example, before starting an OTA upgrade, a network stability check is automatically performed to ensure that the current network connection status is normal, so as to ensure that the wireless connection is stable enough to avoid data loss or errors caused by network instability during the upgrade process.

[0137] For example, to avoid possible interference with the vehicle's electronic system during the charging process and to ensure that the upgrade process is not affected by external electrical influences, it is necessary to ensure that the charging gun is not connected.

[0138] After determining that the target vehicle meets the preset upgrade conditions, the embodiment of the present application automatically performs a silent upgrade on the vehicle without the need for personnel to perform click operations on the vehicle computer, which can effectively improve the efficiency of the vehicle OTA upgrade.

[0139] The embodiment of the present application uses the preset threshold range, the gear position is P gear, the network connection status is normal and the charging gun is not connected as the conditions for judging whether the target vehicle meets the preset upgrade conditions, thereby avoiding the risk of interruption of the target vehicle during the OTA upgrade process, reducing interference or damage caused by accidental movement during the upgrade process, and avoiding possible interference to the vehicle's electronic system during the charging process, ensuring that the upgrade process is not affected by external electrical factors, thereby effectively improving the efficiency and safety of the vehicle's OTA upgrade.

[0140] In an embodiment of the present invention, the software of the controller to be upgraded is downloaded according to the OTA upgrade task, and there is no need to download the version data of the controller whose software version data is the latest. When performing OTA upgrade, only the software-upgradeable controller needs to be OTA upgraded.

If the version of the ECU is not the latest version, and the versions of the vehicle infotainment system and the advanced driver assistance system are the latest versions, only the corresponding version data is downloaded and OTA upgraded for the ECU, and the version download and upgrade of the vehicle infotainment system and the advanced driver assistance system are skipped. This can effectively reduce the repeated download and upgrade of software version data, thereby effectively improving the efficiency of vehicle OTA upgrades.

[0141] In an optional manner, performing OTA upgrade on the target vehicle includes:

[0142] Download the software of the controller to be upgraded according to the OTA upgrade task;

[0143] Determining that the software of the controller to be upgraded meets a preset upgrade requirement, and performing OTA upgrade on the software of the controller to be upgraded;

[0144] The preset upgrade requirements include one or more combinations of the following: software serial number, controller name and logical address.

[0145] In the embodiment of the present invention, the software serial number is the version number or serial number of the software, which can be used to identify different software versions. The software serial number includes the major version number, minor version number, revision number and build number, etc. The controller name is the controller name corresponding to the software to be upgraded; the logical address is the location in the computer system where the software is loaded into the memory.

[0146] The embodiment of the present application verifies the software serial number, controller name and logical address, and automatically enters the OTA upgrade when at least one of the three pieces of information is consistent with the target software to be upgraded. If all three pieces of information are verified to be wrong, the OTA upgrade platform automatically reports an error and stops the OTA upgrade task, ensuring that the correct software version data can be upgraded, thereby improving the accuracy and reliability of vehicle OTA upgrades.

[0147] In an optional manner, before performing OTA upgrade on the target vehicle, the following steps are further included:

[0148] The sales status of the target vehicle is determined to be sold.

[0149] In the embodiment of the present application, it is possible to determine whether the target vehicle has been sold by verifying the vehicle sales status recorded in the vehicle management system. If the vehicle is in the sold state, OTA upgrade cannot be performed, and there is no need to download the corresponding software version data and subsequent upgrade actions. If the vehicle is not sold, OTA upgrade can be performed, and the corresponding software version data is downloaded.

[0150] The embodiment of the present application verifies the sales status of the target vehicle and determines whether to download the corresponding software version data of the upgradeable first controller based on the vehicle sales status, thereby avoiding initiating download and upgrade tasks for vehicles that have already been sold, thereby effectively improving the efficiency of vehicle OTA upgrades.

[0151] In an optional manner, determining that an OTA upgrade is required based on the current software version data and the upgradeable software version data includes:

[0152] The OTA upgrade handheld device compares the current software version data with the upgradeable software version data, and determines whether the target vehicle needs an OTA upgrade based on the comparison results.

[0153] In an embodiment of the present application, the upgradeable software version data may be the latest version data. The current software version data is compared with the upgradeable software version data. If there is inconsistency between the current software version data and the upgradeable software version data, it is determined that the current software version is not the latest version. The controller corresponding to the current software version is an upgradeable controller. At this time, it is determined that the target vehicle needs to be upgraded by OTA.

[0154] The embodiment of the present invention compares the current software version data with the upgradeable software version data, and determines that the target vehicle needs OTA upgrade based on the comparison result. It can accurately determine whether the current software version data needs to be upgraded, and avoid OTA upgrade when the current software version data is the latest software version data, thereby effectively improving the OTA upgrade efficiency.

[0155] In an optional manner, the OTA upgrade method further includes:

[0156] The software version data collected by TBOX is encrypted by shared objects to obtain a software package, and the upgradeable software version data is obtained according to the software package.

The preprocessing includes initialization, packaging, encryption and signature upload, and the creation of the upgradeable software version data is completed after the upload is successful.

[0158] The embodiment of the present application obtains a software package by encrypting a shared object file, and encapsulates the collected software version data into a shared object, which effectively prevents unauthorized access and tampering. It not only ensures the security of the software version data during transmission and storage, but also ensures the correctness of the upgradeable software version data, thereby improving the efficiency of vehicle OTA upgrades.

[0159] Furthermore, encapsulating the collected software version data into a shared object and communicating with the OTA upgrade platform through a single object can reduce the complexity of communication and the amount of data required for transmission, effectively simplifying the communication process, thereby further improving the efficiency of vehicle OTA upgrades.

[0160] In an alternative approach, Figure 7The display interface of the OTA upgrade platform of an embodiment of the present invention is shown, wherein the display interface of the OTA upgrade platform includes a vehicle identification code list, an upgrade version filtering object, an upgrade status filtering object, a creator filtering object and a creation time filtering object.
