[0040] Among them, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, network acceleration services (Content Delivery Network, CDN), and basic cloud computing services such as big data and artificial intelligence platforms.

[0043] It should be noted that Figure 1 The implementation environment scenario diagram of the application upgrade method shown is only an example.

[0044] The solutions provided by the embodiments of the present application are specifically described by the following embodiments. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0045] This embodiment will be described from the perspective of an application upgrade device, which may be specifically integrated in a target controller.

[0046] See also Figure 2 , Figure 2: is a flow chart of an application upgrade method provided in an embodiment of the present application. The application upgrade method is applied to a target controller of a target device, and includes:

[0047] Step S101 : downloading and storing an upgrade file of a target application running in a target controller.

[0048] The target controller may be an electronic control unit (ECU) in a target device, the target device may be a vehicle or other equipment, and the target controller may be an onboard controller in the vehicle, for example, a battery management controller (BMC), a motor control ECU or other controller. The upgrade file may be a file for upgrading a target application running on the target controller, and the target application may be an application running on the target controller.

[0049] Among them, there can be multiple ways to download and store the upgrade file of the target application running in the target controller. For example, you can receive the upgrade file path information of the upgrade file for the target application running in the target controller sent by the first server; through the target application, based on the upgrade file path information, download the upgrade file corresponding to the target application from the second server.

[0050] Among them, the first server can be a server that establishes communication with the target controller. For example, the target controller can establish a communication connection with the first server through the target application, or can establish a communication connection with the first server through a data transmission unit such as an online storage module (DTU). The specific connection method is not limited in this embodiment of the present application. Optionally, the first server can be a cloud platform that can be used to communicate with the target controller. The upgrade file path information can be a path for obtaining the upgrade file of the target application, and the second server can be a server that stores the upgrade file of the target application.

[0051] In this way, by setting up a server that communicates with the target controller and a server that stores upgrade files separately, the security of data transmission and application upgrades can be improved and the risk of application upgrades can be reduced.

[0052] Optionally, there may be multiple ways to download and store the upgrade file of the target application running in the target controller. For example, the target device may include an online storage module, which may receive upgrade file path information for the upgrade file of the target application running in the target controller sent by the first server through the online storage module, detect whether the upgrade file path information exists in the online storage module, and when the existence of the upgrade file path information is detected, download the upgrade file of the target application based on the upgrade file path information through the target application and store it in the online storage module.

[0053] The online storage module may be a module that establishes a communication connection with the first server and is used for data transmission of the upgrade file, for example, it may be a storage module used by a remote communication terminal (TBOX) or other related vehicle-mounted terminals. Optionally, the online storage module may be a supplier module, and the target controller may control the online storage module to communicate with the first server through a preset control instruction protocol (such as AT instructions, a dedicated instruction set of a DTU module).

[0054] In one embodiment, the target controller is a battery management controller (BMC_MCU) as an example, please refer to Figure 3 , Figure 3 It is a schematic diagram of the overall architecture of an application upgrade method provided in an embodiment of the present application, wherein the target controller runs a target application (BMC_APP), and a seamless upgrade program (APP_OTA) is added to the target application, which is used to execute the application upgrade method provided in an embodiment of the present application to achieve seamless upgrade of the target application. When there is an upgrade file that needs to be upgraded in the target application of the target controller, the second server (FTP File Server) storing the upgrade file can notify the first server (cloud platform) to send information such as the upgrade file path information of the upgrade file that needs to be upgraded in the target application to the first server, so that the first server can send the upgrade file path information and other information to the online storage module (DTU module) corresponding to the target controller in JSON (JavaScript Object Notation, a lightweight data exchange format) format through the transmission control protocol (TCP), so that the target controller can use the universal asynchronous receiver and transmitter (UART) and AT instructions to detect whether the upgrade file path information and other information of the upgrade file that needs to be upgraded is stored in the online storage module. When the upgrade file path information and other information of the upgrade file that needs to be upgraded is detected, the online storage module can be triggered to download the upgrade file to the second server based on the upgrade file path information through the file transfer protocol (File Transfer Protocol, FTP for short), and cache it in the online storage module.

[0055] In one embodiment, before downloading the upgrade file of the target application running in the target controller, it can be determined whether the version of the upgrade file to be upgraded is a new version, so as to prevent the reverse upgrade or the upgrade of the same version file, which causes a waste of central processing unit (CPU) resources. For example, when the server sends the upgrade file path information, it can also send the version number of the corresponding upgrade file, so that the version number of the upgrade file to be upgraded can be compared with the version number of the currently running target application, so that when the version number of the upgrade file to be upgraded is greater than the version number of the currently running target application, the upgrade file of the target application running in the target controller can be downloaded to upgrade the target application.

[0056] Optionally, file information of the upgrade file to be upgraded of the target application can also be obtained. The file information may include the version number of the upgrade file to be upgraded and some predetermined check values ​​(CRC32) and other information. The check value can be used to determine whether the current upgrade file is reliable, so as to identify whether there is any difference between the upgrade file and the file currently running on the target controller based on the file information, thereby confirming whether the upgrade file to be upgraded is the file that needs to be upgraded, thereby preventing reverse upgrades or upgrades of the same version of files, which would cause a waste of CPU resources.

[0057] Step S102, detecting the operating status of the target device.

[0058] Among them, the operating status can indicate the task occupancy, driving status and other information of the target device. For example, it can include the operating status of the target device and the operating status of the target controller. The operating status of the target device can include information such as driving status and vehicle speed. The operating status of the target controller can include task occupancy, whether it is busy and other information.

[0059] Step S103: if the running state meets the preset transmission condition, the stored upgrade file is transmitted to the data storage space corresponding to the target controller through the target application.

[0060] The preset transmission condition may be a condition that satisfies the transmission of the upgrade file, and the data storage space may be a storage space corresponding to the target controller for storing the upgrade file.

[0061] Optionally, the preset transmission condition may include the target device being in a first preset operating state and / or the target controller being in a second preset operating state. The first preset operating state may be an operating state that the target device is in when the upgrade file is transmitted. For example, the first preset operating state may include at least one of the target device being in a normal driving state and the target device's operating speed being no greater than a preset speed threshold. The normal driving state may be a driving state in which the target device does not experience a collision, insulation failure, emergency deceleration, or rapid acceleration. The preset speed threshold may be a pre-set critical value of the speed. When the target device's operating speed is greater than the critical value, it may be considered that the target device is running too fast, and the application upgrade is not performed at this time to avoid affecting the normal operation of the target device.

[0062] When the target device is not in the first preset operating state and / or the target controller is not in the second preset operating state, for example, the target device is speeding too fast, the user is performing urgent acceleration and deceleration operations, or the target application is running an algorithm with high CPU usage and encounters an emergency failure, etc., because these situations are tasks that require a large amount of resources to be invested by the target controller to process, the conditions for upgrading file transmission are not met at this time, and it is necessary to suspend the upgrading file transmission first, and continue the upgrading file transmission after the emergency task processing is completed, so as to achieve seamless transmission of the upgrading file.

[0063] The second preset running state may include that the target controller does not include the target task in the tasks currently running, and the memory occupancy rate of the target controller is less than at least one of the preset thresholds. The target task may be a task whose priority meets the conditions and / or the target task is a task whose running time is greater than the preset time. The task that meets the priority conditions may be a task with a higher task priority among the tasks running the target controller. The target task whose running time is greater than the preset time may be a task with a longer running time. The running of the target task will cause the CPU load of the target device or the target controller to be too high. During the running of the target task, the application upgrade of the target application will not be performed to prevent the target controller from being overloaded and causing the program to run stuck, so as to avoid affecting the normal operation of the target device, so as to achieve a seamless upgrade of the target application and improve the efficiency of application upgrade.

[0064] Among them, if the operating status meets the preset transmission conditions, there can be multiple ways to transfer the stored upgrade file to the data storage space corresponding to the target controller through the target application. For example, the upgrade file may include multiple data packets. If the operating status meets the preset transmission conditions, a data packet can be transmitted to the data storage space corresponding to the target controller through the target application. Then, the step of detecting the operating status of the target device can be returned until all data packets of the upgrade file are transferred to the data storage space corresponding to the target controller.

[0065] In this way, after downloading the upgrade file, the operating status of the target device can be detected in real time through the target application. When the operating status meets the preset transmission conditions, a data packet of the upgrade file can be transmitted to the data storage space corresponding to the target controller through the target application. During the process of transmitting the data packet, the target controller is still monitoring the operating status of the target device. When the operating status meets the preset transmission conditions, the next data packet of the upgrade file is transmitted to the data storage space corresponding to the target controller through the target application until all data packets of the upgrade file are transmitted to the data storage space corresponding to the target controller.

[0066] Optionally, if the running status meets the preset transmission conditions, after a data packet is transmitted to the data storage space corresponding to the target controller through the target application, if it is detected that the running status does not meet the preset transmission conditions, the storage address information of the target data packet is recorded, and then, the step of detecting the running status of the target device can be returned. In the process of returning to detect the running status of the target device, if it is detected that the running status meets the preset transmission conditions, the untransmitted data packets continue to be transmitted to the data storage space corresponding to the target controller based on the storage address information.

[0067] The storage address information may be information indicating the storage address of a target data packet, and the target data packet may be a data packet that is last transmitted to the data storage space, that is, a data packet that is last successfully stored in the data storage space.

[0068] Among them, based on the storage address information, there may be multiple ways to continue to transmit the untransmitted data packet to the data storage space corresponding to the target controller. For example, the address offset of the next data packet may be performed on the storage address information and the length of the data packet to obtain the storage address of the next data packet, that is, the storage address of the next untransmitted data packet, which is recorded in the data storage unit (Dflash). Therefore, when it is detected that the operating status meets the preset transmission conditions, the transmission completion flag of the transmission process of transferring the upgrade file to the data storage space of the target controller can be read. When the transmission completion flag is not set, it may indicate that there is a transmission interruption in the transmission process of transferring the upgrade file to the data storage space of the target controller. Therefore, the storage address of the next untransmitted data packet corresponding to the upgrade file can be obtained in Dflash, so that according to the storage address of the next data packet, the untransmitted data packet can continue to be transmitted to the data storage space corresponding to the target controller.

[0069] In one embodiment, when the upgrade file transmission is interrupted or fails, the storage address of the most recently successfully transmitted data packet can be obtained, so that the address offset can be performed according to the storage address of the most recently successfully transmitted data packet and the length of the data packet, so that the storage address of the next data packet that has not been transmitted can be recorded and recorded in Dflash, so that when the preset transmission condition is met next time, the untransmitted data packet can continue to be transmitted to the data storage space corresponding to the target controller according to the storage address of the next data packet. In this way, the upgrade file transmission process that occupies the most CPU and is the most time-consuming can be performed in a senseless state, and when there is an interruption or failure in the transmission process, the interruption point, that is, the storage address information of the target data packet, is recorded, so that the next time the preset transmission condition is met, the breakpoint is resumed according to the storage address information, and the data transmission method of the upgrade file based on the breakpoint-resume transmission realizes the senseless upgrade of the target application and greatly improves the upgrade efficiency of the target application.

[0070] Optionally, when the upgrade file is stored in an online storage module, during the transmission process of the upgrade file to the data storage space of the target controller, the target controller can obtain data packets of the upgrade file from the online storage module in segments, and transmit the data packets to the data storage space corresponding to the target controller. Then, the integrity of the upgrade file stored in the data storage space corresponding to the target controller can be verified. When the upgrade file meets the integrity requirements, you can wait for subsequent application upgrades.

[0071] In a specific embodiment, take the target controller downloading the upgrade file through the online storage module as an example, please refer to Figure 4 , Figure 4 It is a specific flow diagram of an application upgrade method provided by an embodiment of the present application. In step S1, the target controller detects whether there is an upgrade file of the application to be upgraded in the online storage module. When there is an upgrade file, the application to be upgraded corresponding to the upgrade file can be detected through step S2 to determine whether it is consistent with the currently running application. In the case of inconsistency, the upgrade file can be downloaded through the online storage module, and the running state of the target device can be detected to determine whether the state of the target device meets the preset transmission condition through step S3, so that when the preset transmission condition is met, the first data packet of the upgrade file can be obtained from the online storage module through step S4, and the data packet is transmitted to the data storage space corresponding to the target controller, and the integrity of each data packet is verified. When the transmission is completed, based on step S5, continue to detect whether the preset transmission condition is met at present. When the preset transmission condition is met, based on step S6, the next data packet in the upgrade file is obtained from the online storage module for transmission. When the preset transmission condition is not met, the transmission of the upgrade file is temporarily stopped until the running state of the target device meets the preset transmission condition, and the transmission of the next data packet is continued. Based on step S7, steps S5 and S6 are repeated until all data packets of the upgrade file are transmitted. Then, based on step S8, the transmitted upgrade file may be checked for integrity, and when the upgrade file meets the integrity requirements, the subsequent application upgrade process may be performed.

[0072] Step S104: upgrading the target application based on the upgrade file in the data storage space.

[0073] Among them, there can be multiple ways to upgrade the target application based on the upgrade file in the data storage space. For example, when the internal storage space of the target controller is large enough, the data storage space can be the internal storage space corresponding to the target controller, so that it can receive a power-off instruction. Based on the power-off instruction, the starting storage address of the upgrade file in the data storage space is set to the starting running address of the target application, and the target device is controlled to be in a power-off state. When it is detected that the target device switches from the power-off state to the power-on state, the target application is upgraded based on the starting running address of the target application.

[0074] The power-off instruction may be an instruction to turn off the power of the target device. For example, when the vehicle is locked, the power-off instruction will be triggered to power off the vehicle. The starting storage address may be the starting storage address of the upgrade file in the data storage space, and the starting running address may be the starting address for running the target application. The power-on state may be the state in which the target device is powered on. For example, after the vehicle is started, the vehicle will switch from the power-off state to the power-on state.

[0075] Among them, there are many ways to set the starting storage address of the upgrade file in the data storage space as the starting running address of the target application based on the power-off instruction, and control the target device to be in a power-off state. For example, when a power-off instruction is received, the starting storage address of the upgrade file in the data storage space can be set as the starting running address of the target application through a boot program, and then the target device is controlled to be in a power-off state based on the power-off instruction.

[0076] Optionally, when a power-off command is received, the sleep state of the target device can be briefly delayed. During the delayed sleep period, the starting storage address of the upgrade file in the data storage space can be set to the starting running address of the target application through the boot program, so that the target application can be upgraded without the user noticing, thereby improving the efficiency of application upgrades.

[0077] In this way, when a power-off command is received for the target device, the starting storage address of the upgrade file in the data storage space is quickly set to the starting running address of the target application. Then, when it is detected that the target device switches from a power-off state to a power-on state, the target application is run based on the starting running address of the target application through the boot loader (Bootloader), so that the new version of the target application is run with the new version of the upgrade file, thereby completing the upgrade of the target application without the user noticing, thereby improving the application upgrade efficiency of the target controller.

[0078] Optionally, there may be multiple ways to upgrade the target application based on the upgrade files in the data storage space. For example, when the internal storage space of the target controller is not large enough, the data storage space may be the external storage space corresponding to the target controller, so that a power-off instruction may be received. Based on the power-off instruction, the starting running address of the target application may be obtained. Based on the starting running address of the target application, the upgrade files in the data storage space may be burned into the internal storage space of the target controller. When it is detected that the target device switches from a power-off state to a power-on state, the target application may be upgraded based on the upgrade files in the internal storage space.

[0079] Among them, the external storage space can be an external memory outside the target controller and set for the target controller, and the internal storage space can be an application (APP) area of ​​the target controller. The APP area can be an area divided in the internal memory of the microcontroller for storing application code and data. In this area, the microcontroller can store and execute the user's application code and data, thereby realizing specific functions.

[0080] Among them, there are many ways to burn the upgrade file in the data storage space into the internal storage space of the target controller based on the starting running address of the target application. For example, a boot program can be used to burn the upgrade file into the APP area of ​​the target application in the target controller based on the starting running address of the target application.

[0081] In this way, when it is detected that the target device switches from a power-off state to a power-on state, the program of the upgrade file stored in the APP area of ​​the internal storage space can be run based on the starting running address of the target application, thereby running the new target application and upgrading the target application without the user noticing.

[0082] For example, please refer to Figure 3, an external storage space (ExternFlash IC) can be added to the target controller BMC_MCU, and the external storage space and the online storage module can be communicated and managed through the controller driver (BMC_DRV). The controller driver includes a flash driver (Flash Drv) and a storage module manager (DtuM). The flash driver Flash Drv is used to manage the external storage space Extern Flash IC through the serial bus protocol (SPI), and the storage module manager DtuM is used to manage the online storage space. Therefore, the App_OTA program in the target application can be used to obtain the data packet of the upgrade file from the online storage module, and then transmitted to the external storage space Extern Flash IC. When a power-off instruction is received, the starting running address of the target application can be obtained through the App_OTA program in the target application based on the power-off instruction. Based on the starting running address of the target application, the upgrade file in the external storage space Extern Flash IC is burned to the internal storage space of the target controller through the boot program. Therefore, when it is detected that the target device switches from the power-off state to the power-on state, the upgrade file in the internal storage space can be run through the boot program to run the new target application corresponding to the upgrade file, so as to realize the non-sensing upgrade of the target application.

[0083] Optionally, after the target application is upgraded, the version number of the currently running target application may be uploaded to the cloud platform through the target application to notify the cloud platform whether the application upgrade is successful.

[0084] In one embodiment, if an upgrade failure occurs during the upgrade process of the target application, the target controller can perform autonomous upgrade diagnosis, and then the diagnosed cause can be uploaded to the cloud platform. In this way, the problems encountered during the upgrade process can be intuitively obtained through the background server, and the problems generated during the target application upgrade process can be quickly resolved, thereby improving the efficiency of the application upgrade.

[0085] In the existing application upgrade method for the target controller, the Over-the-Air Technology (OTA) is often used for upgrading. The updated software is uploaded to the OTA center through OTA, and then the software is wirelessly transmitted to the vehicle end through the OTA center for software update. Finally, the vehicle end guides the corresponding controller to update the software through the CAN protocol. However, under this application upgrade method, after receiving the upgrade command, the vehicle computer will put the target ECU that needs to be upgraded in the upgrade state, so that the target ECU is in BootLoader mode, and the rest of the ECUs are in a silent state, which means that the user cannot perform any operation on the vehicle during the entire application upgrade process. The time for a complete upgrade is calculated in minutes, which basically takes more than ten minutes, and may take longer. It is undoubtedly a long wait for the user. In addition, the vehicle controller needs to be upgraded and guided by the vehicle computer or some equipment throughout the process, relying on the traditional automotive universal diagnostic protocol (UDS). The ECU is in a passive state during the entire transmission process. The vehicle computer will send all the corresponding upgrade messages to the ECU that needs to be upgraded at one time and the transmission process cannot be interrupted. Once interrupted, the application upgrade will fail. Therefore, when using OTA for application upgrades, the vehicle will switch the ECU to an upgrade state, so that during the entire upgrade process, the driver cannot perform any operations on the vehicle, resulting in a poor application upgrade experience and, in turn, low application upgrade efficiency.

[0086] To this end, an embodiment of the present application provides an application upgrade method, in which an upgrade file is interactively stored through a server such as a cloud platform and an online storage module corresponding to a target controller ECU. Then, the target application inside the target controller ECU communicates with the online storage module to complete the upgrade of the target application. The cloud platform only needs to send the path-related information of the upgrade file to the online storage module, and the subsequent application upgrade process is fully implemented by the target controller itself. When the target controller detects that there are files in the online storage module that need to be updated, the target controller can judge whether the currently executed task is busy, whether the operating status is normal, etc. according to its own and the running status of the whole vehicle, and actively obtain the data of the upgrade file from the online storage module, without relying on the upper computer or T-BOX (related on-board diagnostic instrument) to issue related upgrade instructions. If the whole vehicle needs to perform some urgent tasks or some tasks that are not suitable for upgrading during the transmission process, the transmission is stopped at this time, and the transmission is continued until the conditions are met until completion, thereby realizing a seamless upgrade of the target application. The application upgrade method provided in the embodiment of the present application is used to upgrade the application of the target controller. It is an autonomous and seamless upgrade process. The entire process is carried out in the target application, which means that the user can perform any operations such as discharging and charging the vehicle, and there is no need to wait for the application upgrade process. The upgrade duration is short, and the user will not feel anything during the entire process, thereby improving the customer experience.

[0087] Furthermore, in the existing application upgrade method using OTA, once a failure occurs during the transmission of the upgrade file, the transmission has to start from the beginning in real time. However, the autonomous and seamless application upgrade method provided in the embodiment of the present application can record the failure breakpoint when the upgrade file transmission fails, so that the transmission can be resumed from the breakpoint when the preset transmission conditions are met, greatly improving the application upgrade efficiency.

[0088] In addition, in the existing application upgrade method using OTA, multiple modules are required to cooperate, relying on the CAN bus, the upgrade time is long, the ECU is passively updated throughout the process and the vehicle cannot operate normally during the entire process. The autonomous and senseless application upgrade method provided in the embodiment of the present application can be upgraded spontaneously by the ECU, without relying on the guidance of any device, and the vehicle can be used normally during the application upgrade process, making the application upgrade of the target controller more flexible and intelligent, and able to autonomously respond to various complex working conditions, thereby effectively improving the success rate of application upgrades and user experience.

[0089] As can be seen from the above, the embodiment of the present application downloads and stores the upgrade file of the target application running in the target controller; detects the operating status of the target device; if the operating status meets the preset transmission conditions, the stored upgrade file is transmitted to the data storage space corresponding to the target controller through the target application; and the target application is upgraded based on the upgrade file in the data storage space. In this way, the operating status of the target device is detected by the target controller, and when the operating status meets the preset transmission conditions, the stored upgrade file is transmitted to the data storage space corresponding to the target controller through the target application, thereby upgrading the target application based on the upgrade file in the data storage space, and the upgrade process of the target application is actively controlled by the target controller, so as to realize the non-sensing upgrade of the target application running in the target controller, avoid the impact of the upgrade process of the target application on the operation of the target device, effectively improve the application upgrade experience, and then improve the efficiency of application upgrade.

[0115] In one embodiment, the data storage space is an internal storage space corresponding to the target controller, and the upgrade module 204 is used to:
