[0035] Based on the above hardware structure, the OTA-based production line software breakpoint method embodiment of the application is proposed.

[0036] Reference Figure 2 , Figure 2 The flowchart of the first embodiment of the OTA-based production line software breakpoint method of the application is shown.

[0037] In the first embodiment, the OTA-based production line software breakpoint method comprises the following steps: Step S10, dynamically calculating a to-be-updated controller needing software updating in vehicle assembly, and importing a software flashing package of the to-be-updated controller into a reserved storage area of a vehicle controller.

[0038] It should be noted that the to-be-updated controller needing software updating in the vehicle production line vehicle assembly process can be determined by dynamic calculation, and then the software flashing package of the to-be-updated controller needing updating is imported into the reserved storage area of the vehicle controller.

[0039] In specific implementation, the to-be-updated controller refers to a small-capacity electronic control unit (ECU) in a vehicle, such as a body control module (BCM), a vehicle lamp control unit, an air conditioning control unit, etc., which usually has a small storage space and frequent software updating requirements; the vehicle controller is an in-vehicle infotainment (IVI) controller, which usually has a large storage capacity and is used to process multimedia, navigation, voice interaction, etc. The vehicle controller is built-in with an OTA component for triggering software updating of other controllers, and a storage area is reserved for temporarily storing software flashing packages of other controllers.

[0040] Step S20, after detecting that the vehicle assembly is completed, triggering the over-the-air (OTA) component in the vehicle controller to call the software flashing package in the reserved storage area for controller upgrading.

[0041] It should be understood that after detecting that the vehicle needing upgrading is completed, the over-the-air (OTA) component of the vehicle controller can be triggered to call the software flashing package in the reserved storage area for controller upgrading.

[0042] Step S30, verifying the software flashing package after flashing, and deleting the software flashing package in the reserved storage area through pre-delivery inspection (PDI) after verification.

[0043] It can be understood that after verifying the software flashing package after flashing, the software flashing package in the reserved storage area can be deleted through pre-delivery inspection (PDI) after verification.

[0044] The embodiment calculates the to-be-updated controller needing software updating in vehicle assembly through dynamic calculation, imports the software flashing package of the to-be-updated controller into the reserved storage area of the vehicle controller, triggers the over-the-air (OTA) component in the vehicle controller to call the software flashing package in the reserved storage area for controller upgrading after detecting that the vehicle assembly is completed, checks the software flashing package after flashing, and deletes the software flashing package in the reserved storage area through pre-delivery inspection (PDI) after passing the check, so that the software flashing of a large-capacity controller can be implemented without relying on manual flashing, the vehicle offline quality is improved, the production line circulation efficiency is improved, the production line software flashing cost is reduced, the method has scalability and flexibility, the flashing is stable and reliable, the downloading time is reduced, the flashing efficiency is improved, and the implementation speed and efficiency of the production line software breakpoint based on OTA are improved.

[0045] Further, Figure 3 The flowchart of the second embodiment of the OTA-based production line software breakpoint method of the present application is shown in Figure 3 The second embodiment of the OTA-based production line software breakpoint method of the present application is proposed based on the first embodiment, and in the embodiment, the step S10 specifically includes the following steps. In step S11, the to-be-updated controller needing software updating in vehicle assembly is dynamically calculated through the linkage of the manufacturing execution system (MES) and the software baseline management system (SBMS).

[0046] It should be noted that the to-be-updated controller needing software updating in vehicle assembly can be dynamically calculated through the linkage of the manufacturing execution system (MES) and the software baseline management system (SBMS).

[0047] Further, the step S11 specifically includes the following steps. The software of each controller of the vehicle is compared through the manufacturing execution system (MES) and the software baseline management system (SBMS), and the software difference information is sent to the flashing control system. The to-be-updated controller needing software updating in vehicle assembly is dynamically calculated through the flashing control system.

[0048] It can be understood that the software of each controller of the vehicle is compared through the manufacturing execution system (MES) and the software baseline management system (SBMS), and the software difference information is sent to the flashing control system. The to-be-updated controller needing software updating in vehicle assembly can be dynamically calculated through the flashing control system.

[0049] Step S12, the software flashing package of the to-be-updated controller is imported into the reserved storage area of the car machine controller through the single-piece flashing station.

[0050] It should be understood that the software flashing package of the to-be-updated controller can be imported into the reserved storage area of the car machine controller through the single-piece flashing station.

[0051] Further, the step S12 specifically includes the following steps: The single-piece flashing station receives the software flashing package of the to-be-updated controller according to the preset flashing instruction, and imports the software flashing package into the reserved storage area of the car machine controller.

[0052] It can be understood that the single-piece flashing station of the car machine transmits the upgrade package to the car machine through the flashing control system, and after completing the software flashing of the car machine controller, the single-piece flashing station flashes the dynamically calculated to-be-updated controller to the designated storage area of the car machine through the preset instruction.

[0053] In specific implementation, before dynamic calculation, the single-piece flashing station and the electrical inspection system, the software management system, the manufacturing system, etc. can be imported, the flashing controller system is developed, the difference controller is dynamically calculated, the to-be-updated controller information and version are obtained, the controller system is developed, the to-be-updated controller task is issued to the single-piece flashing station, and after the car machine controller is upgraded, the single-piece flashing station transmits the to-be-updated controller software package to the designated memory of the car machine controller, that is, to the reserved storage area.

[0054] Through the above scheme, the to-be-updated controller needing software updating in the whole vehicle assembly is dynamically calculated through the linkage of the manufacturing execution system MES and the software baseline management system SBMS in the embodiment; the software flashing package of the to-be-updated controller is imported into the reserved storage area of the car machine controller through the single-piece flashing station, so that the flashing of the large-capacity controller can be realized, the artificial flashing is not needed, the vehicle off-line quality is improved, and the production line circulation efficiency is improved.

[0055] Further, Figure 4 The flowchart of the third embodiment of the OTA-based production line software breakpoint method of the application is shown in FIG. 6. Figure 4 The third embodiment of the OTA-based production line software breakpoint method of the application is proposed based on the first embodiment, and in the embodiment, the step S20 specifically includes the following steps: Step S21, after detecting that the whole vehicle assembly is completed and the whole vehicle is powered on, the software flashing package in the reserved storage area is automatically triggered and called through the over-the-air download (OTA) component in the car machine controller.

[0056] It should be noted that after detecting that the whole vehicle assembly is completed and detecting that the whole vehicle is powered on, the software flashing package in the reserved storage area can be automatically triggered and called by the over-the-air (OTA) component in the vehicle machine controller.

[0057] In a specific implementation, after the whole vehicle assembly is completed and the whole vehicle is powered on, the OTA component in the vehicle machine automatically triggers the stored flashing package upgrade operation.

[0058] Step S22, according to the software flashing package, the upgrade flashing operation of the to-be-updated controller is completed.

[0059] It can be understood that, according to the software flashing package, the upgrade flashing operation of the to-be-updated controller can be completed.

[0060] It should be noted that the OTA component in the embodiment has two modes, namely factory mode and user mode, which can be switched by external instructions. The OTA component defaults to factory mode and switches to user mode (i.e. traditional OTA component state) when it is put into storage after completing all detections. In factory mode, the OTA component can realize traditional online flashing. The OTA component in factory mode can receive the in-field upgrade task issued by the platform. The platform dynamically issues upgrade requirements according to the target version and the current vehicle software version.

[0061] In a specific implementation, the vehicle machine controller with the embedded OTA component completes software filling in the factory. The OTA component has about 5G (customizable development) memory. In the state that the vehicle machine controller has not been installed in the vehicle, the vehicle machine controller is flashed by single-piece flashing. After completing the upgrade of the vehicle machine controller itself, the software difference list issued by the platform is received, and the software package that needs to be upgraded for the vehicle model is imported into the memory of the OTA component in advance. After the vehicle machine controller completes assembly, the platform receives information and issues upgrade instructions to the OTA component through the industrial network after the vehicle machine controller meets the upgrade conditions on the production line. This process eliminates the process of downloading the upgrade package because the controller software package that needs to be upgraded has been imported in advance. The OTA component is embedded, and the flashing of the required controller of the whole vehicle is completed when the vehicle is still in the assembly and circulation process on the production line.

[0062] The embodiment can realize the flashing of large-capacity controllers without relying on manual flashing, improve the vehicle off-line quality, improve the production line circulation efficiency, and improve the implementation speed and efficiency of the production line software breakpoint based on OTA.

[0063] Further, Figure 5 A flowchart of a fourth embodiment of the OTA-based production line software breakpoint method of the present application is shown in FIG. 4. Figure 5 As shown in FIG. 4, the fourth embodiment of the OTA-based production line software breakpoint method of the present application is based on the first embodiment, and in this embodiment, the step S30 specifically includes the following steps: Step S31: After detecting that the vehicle to be inspected arrives at the electrical inspection station, the current software version of the software flashing package after flashing of the vehicle to be inspected is obtained, and the current software version is checked against the version number of the corresponding latest software version.

[0064] It should be noted that after detecting that the vehicle to be inspected arrives at the electrical inspection station, the current software version of the software flashing package after flashing of the vehicle to be inspected can be obtained. By comparing the current software version with the version number of the corresponding latest software version, the version number can be checked, i.e., it can be determined whether the current software version of the software flashing package is the latest version.

[0065] Step S32: When the version number of the current software version is consistent with the version number of the latest software version, it is determined that the check is passed.

[0066] It can be understood that when the version number of the current software version is consistent with the version number of the latest software version, it can be determined that the check is passed, i.e., at this time, the software flashing package is the latest software flashing package.

[0067] Step S33: After detecting that the vehicle to be inspected arrives at the pre-delivery inspection (PDI) station, the software flashing package in the reserved storage area is deleted.

[0068] It should be understood that after detecting that the vehicle to be inspected arrives at the pre-delivery inspection (PDI) station, the software flashing package in the reserved storage area can be deleted, thereby releasing the memory of the vehicle machine controller.

[0069] In a specific implementation, after the upgrade is completed, the whole vehicle is inspected to meet the warehouse entry standard, then the electrical inspection is performed, the OTA component is switched from the factory mode to the user mode, after the OTA component is switched to the user mode, the after-sales operation and maintenance personnel can issue an OTA upgrade task to the user vehicle according to the normal user upgrade demand, which is similar to the traditional OTA function.

[0070] It can be understood that the OTA component has higher flexibility in the factory mode, data transmission through the industrial network is safer, authentication is simplified, and the controller software package that needs to be flashed has been delivered to the OTA component in advance by flashing the single vehicle machine controller, reducing the time needed for downloading, maximizing the upgrade process, avoiding upgrade failure caused by additional software download, and additional time-consuming problems; The OTA component supports parallel flashing and can upgrade different controllers at the same time to improve upgrade efficiency. The platform can dynamically upgrade the parallel upgrade sequence according to the controller category that needs to be upgraded, and then the OTA component upgrades in the corresponding order according to the sequence issued by the platform. The OTA component is in the form of software, which is more flexible and has no device and station restrictions. As long as the vehicle state meets the requirements on the production line, software flashing can be started, which truly helps to realize the demand of controller software and hardware separation of the host factory, and the software version of all controllers is controlled by the host factory, reducing the investment of software switching iteration.

[0071] Further, the step S33 specifically includes the following steps: After detecting that the vehicle to be detected reaches the PDI station, the vehicle machine controller receives a software package deletion instruction, and in response to the software package deletion instruction, the software flashing package in the reserved storage area is deleted.

[0072] It can be understood that after the upgrade is completed, the vehicle reaches the electrical inspection station and is checked according to the latest software version. After the vehicle controller software package is upgraded, the vehicle reaches the PDI station, and the device sends a software package deletion instruction to the vehicle machine controller, and the vehicle machine controller deletes the stored flashing package to release the memory.

[0073] In specific implementation, after the whole vehicle assembly is completed and the vehicle completes the high voltage, the OTA component in the vehicle machine detects the high voltage and automatically executes the stored flashing package flashing. Taking 2 electrical inspection stations and 1 PDI station as an example, after the vehicle reaches the 2 electrical inspection stations, the software version is checked after the flashing is completed in the electrical inspection station combined with the latest software version. After the vehicle reaches the PDI station, a software package deletion instruction is sent to the vehicle machine controller, and the vehicle machine controller deletes the stored flashing package according to the software package deletion instruction.

[0074] It should be noted that this embodiment can solve the flashing problem of all high-capacity controllers, improving flashing efficiency. The single flashing station can be pre-stored, so the upgrade package of the controller to be flashed can be imported in advance, which is feasible. Through the OTA component, the flashing is stable and reliable. The flashing station is preset in advance, reducing download time and ensuring flashing reliability. By integrating existing resources to realize the flashing of the whole vehicle controller, it is possible to realize the flashing of small-capacity controllers with minimal investment, which reflects economic efficiency. Furthermore, the OTA component can dynamically determine the flashing order and adopt parallel flashing to improve flashing efficiency, which has scalability.

[0075] This embodiment, through the above-described scheme, dynamically calculates the controllers requiring software updates during vehicle assembly and imports their software flashing packages into the reserved storage area of ​​the vehicle controller. Upon detection of completed vehicle assembly, the over-the-air (OTA) component within the vehicle controller is triggered to call the software flashing package in the reserved storage area to upgrade the controller. The flashed software flashing package is then verified; if successful, it is deleted from the reserved storage area via a pre-delivery inspection (PDI). This approach enables flashing of large-capacity controllers without manual intervention, improving vehicle off-line quality, increasing production line efficiency, reducing production line software flashing costs, and providing scalability, flexibility, stable and reliable flashing, reduced download time, and improved flashing efficiency. It also enhances the speed and efficiency of OTA-based production line software breakpoint implementation.

[0076] Accordingly, the present invention further provides a production line software breakpoint device based on OTA.
