Description

Technical Field

[0001] This invention relates to the field of automotive industry technology, and in particular to a self-inspection control method, device and server for vehicle production and maintenance. Background Technology

[0002] Currently, related technologies suggest that during vehicle production, production lines need to be equipped with functional testing equipment for electrical inspection and programming. At the end of vehicle assembly, the functional testing equipment is used to perform electrical and programming inspections on the vehicle. In addition, after-sales service requires the development of after-sales diagnostic equipment, with each repair station needing to be equipped with at least one diagnostic device for daily maintenance. Therefore, this solution requires investment in the development of functional testing and after-sales diagnostic instruments in the early production and after-sales stages of the project, as well as secondary development work during later product upgrades. This extends the testing cycle, reduces testing efficiency, and increases development costs. Furthermore, due to the differences in equipment and data sources used in production and after-sales, multiple developments can lead to data deviations, thereby reducing the accuracy of production, maintenance, and testing. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a self-inspection control method, device and server for vehicle production and maintenance, which can significantly improve the accuracy and efficiency of fault detection in the process of vehicle production and maintenance.

[0004] In a first aspect, embodiments of the present invention provide a self-inspection control method for vehicle production and maintenance. The method is applied to a self-inspection control system for vehicle production and maintenance. The method includes: when the power supply of an ordered vehicle is detected to be on, connecting an information domain controller to the vehicle's manufacturing execution system based on a key sent by a vehicle networking service platform; sending vehicle information provided by the manufacturing execution system to the information domain controller, so that the information domain controller performs a self-inspection process to prevent errors in the vehicle's electronic control system based on the vehicle information, wherein the vehicle information includes: vehicle configuration information, controller list and version, software version, flashing software list, software package, and electronic testing program; after the self-inspection process of the vehicle's electronic control system passes, switching the information domain controller to production mode, and using the electronic testing program and a set of external cameras to perform a production self-inspection process on the vehicle's electronic control components and the actions of external equipment, so that the ordered vehicle can be delivered after the vehicle's production self-inspection passes.

[0005] In one implementation, the step of connecting the information domain controller to the vehicle's manufacturing execution system based on the key sent by the vehicle-to-everything (V2X) service platform includes: when the power of the ordered vehicle is detected to be turned on, starting the information domain controller by sending a power-on command to the information domain controller, enabling the information domain controller to connect to the V2X service platform via a wireless network; encrypting the key in the manufacturing execution system through the V2X service platform and sending it to the information domain controller, enabling the information domain controller to switch to VPN and connect to the manufacturing execution system.

[0006] In one implementation, before sending the vehicle information provided by the Manufacturing Execution System to the information domain controller, the process includes: obtaining order information from the order system through the Enterprise Resource Management System, wherein the order information includes: order delivery requirement information, vehicle configuration information, and customer requirement information; based on the order information, performing data matching processing on the automotive enterprise master data information, software-related information, and component-related information in the Product Development Management System to determine the vehicle information of the ordered vehicle, and sending the vehicle information to the Manufacturing Execution System.

[0007] In one implementation, the step of switching the information domain controller to production mode includes: performing software flashing and parameter configuration processing on the information domain controller according to the controller list and version, software version, flashing software list and software package, so as to register the ordered vehicles, and switching the information domain controller to production mode by loading factory network information.

[0008] In one embodiment, the step of performing a production self-inspection process on the vehicle's electronic control components and external equipment using an electronic inspection program and a set of external cameras includes: collecting video information of the ordered vehicle through the set of external cameras, and determining the actions of the vehicle's external equipment by performing action recognition processing on the video information; when the actions of the vehicle's external equipment corresponding to each external device of the ordered vehicle are consistent with the preset standard equipment actions, and the detection results of the electronic inspection program for each vehicle's electronic control component are normal, the ordered vehicle is determined to have passed the production self-inspection.

[0009] In one implementation, the method further includes: when the vehicle production self-inspection fails, storing and recording the testing process data of the vehicle's electronic control components and the video information of the ordered vehicle, and sending on-site retest reminder information to the quality inspector's terminal.

[0010] In one implementation, after the step of delivering the ordered vehicle, the process includes: tracking the vehicle status of the ordered vehicle in real time; switching the information domain controller to shipping mode when the ordered vehicle has completed log uploading and network parameter initialization; switching the information domain controller to customer mode when the ordered vehicle has been sold; and switching the information domain controller to maintenance mode when the ordered vehicle has entered a repair shop or a customer has called for roadside assistance.

[0011] In one implementation, when the log upload and network parameter initialization of the order vehicle are detected to be completed, the step of switching the information domain controller to the shipping mode includes: recording the data information generated by the order vehicle during the production self-inspection process as a production process log; when the production process log is uploaded to the manufacturing execution system, deleting the vehicle information of the corresponding order vehicle from the manufacturing execution system, and switching the information domain controller to the shipping mode.

[0012] In one implementation, after the step of switching the information domain controller to maintenance mode when an ordered vehicle is detected to enter a service station or a customer calls for roadside assistance, the method includes: retrieving production data from the production process log and comparing the production data with the current vehicle data to provide maintenance data support.

[0013] Secondly, embodiments of the present invention also provide a self-inspection control device for vehicle production and maintenance. The device is applied to a self-inspection control system for vehicle production and maintenance. The device includes: a platform communication module, which connects an information domain controller to the vehicle's manufacturing execution system based on a key sent by a vehicle networking service platform when the power supply of an ordered vehicle is detected; an information interaction module, which sends vehicle information provided by the manufacturing execution system to the information domain controller, enabling the information domain controller to perform error-proofing self-testing of the vehicle's electronic control system based on the vehicle information. The vehicle information includes: configuration information, controller list and version, software version, flashing software list, software package, and electronic testing program; and a vehicle self-testing module, which switches the information domain controller to production mode after the vehicle's electronic control system error-proofing self-test passes, and uses the electronic testing program and a set of external cameras to perform production self-testing of the vehicle's electronic control components and external equipment actions, so that the ordered vehicle can be delivered after the vehicle production self-test passes.

[0014] Thirdly, embodiments of the present invention also provide a server, including a processor and a memory, the memory storing computer-executable instructions executable by the processor, the processor executing the computer-executable instructions to implement any of the methods provided in the first aspect.

[0015] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer-executable instructions, which, when invoked and executed by a processor, cause the processor to implement any of the methods provided in the first aspect.

[0016] The embodiments of the present invention bring the following beneficial effects:

[0017] This invention provides a self-check control method, device, and server for vehicle production and maintenance. When the power to an ordered vehicle is detected to be on, the method connects the information domain controller to the vehicle's manufacturing execution system (MES) based on a key sent by the vehicle network service platform. The vehicle information provided by the MES is then sent to the information domain controller, enabling the controller to perform a self-check to prevent errors in the vehicle's electronic control system. The vehicle information includes: vehicle configuration information, controller list and version, software version, flashing software list, software package, and electronic testing program. Finally, after the vehicle's electronic control system passes the self-check, the information domain controller... The domain controller switches to production mode and uses an electrical inspection program and external camera array to perform production self-inspection on the vehicle's electronic control components and external equipment. After the vehicle production self-inspection passes, the ordered vehicle is delivered. This embodiment of the invention can eliminate the diagnostic equipment used in traditional production and after-sales service. From production to after-sales maintenance after delivery to the user, everything is carried out by the information domain controller. During the vehicle's off-line electrical inspection and after-sales service, image recognition and vehicle networking technologies are used to achieve production error prevention control, vehicle configuration data control, and software version control, which can significantly improve the accuracy and efficiency of fault detection during vehicle production and maintenance.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Currently, related technologies propose that during vehicle production, production lines need to be equipped with functional testing equipment for electrical inspection and programming. At the end of vehicle assembly, this equipment is used for programming and electrical inspection. Furthermore, after-sales service requires the development of diagnostic equipment, with each repair station needing at least one diagnostic device for routine maintenance. Therefore, this solution requires investment in the development of functional testing and after-sales diagnostic tools during the early production and after-sales phases, as well as secondary development work during later product upgrades. This extends the testing cycle, reduces testing efficiency, and increases development costs. Moreover, due to differences in equipment and data sources used in production and after-sales, multiple development efforts can lead to data discrepancies, thereby reducing the accuracy of production, maintenance, and testing. With the development of vehicle networking technology, automakers have developed remote vehicle control, diagnostics, and OTA (Over-The-Air) updates (i.e., functional testing used in vehicle production). After-sales service uses diagnostic tools, while automakers' remote services utilize vehicle networking service platforms and remote terminals. These three areas overlap technically. Current vehicle electrical architecture is primarily evolving towards domain control, with controllers possessing very strong computing power. Vehicles also utilize various networking methods, including CAN, Wi-Fi, Ethernet, 4G, and 5G. Based on this, the self-inspection control method, device, and server for vehicle production and maintenance provided by this invention can eliminate the need for traditional diagnostic equipment used in production and after-sales service. From production to after-sales maintenance after delivery to the user, everything relies on the information domain controller. During vehicle off-line electrical inspection and after-sales service, image recognition and vehicle networking technologies are used to achieve production error prevention control, vehicle configuration data control, and software version control, significantly improving the accuracy and efficiency of fault detection during vehicle production and maintenance.

[0029] To facilitate understanding of this embodiment, a self-inspection control method for vehicle production and maintenance disclosed in this invention will first be described in detail. This method is applied to the self-inspection control of vehicle production and maintenance. To facilitate understanding of the self-inspection control system for vehicle production and maintenance, this invention provides a structural schematic diagram of the self-inspection control system for vehicle production and maintenance, as shown below. Figure 1As shown, the system includes: an order system, an Enterprise Resource Planning (ERP) system, a Product Development Management (PDM) system, a Manufacturing Execution System (MES) system, a Vehicle Service Platform (TSP) system, an after-sales service system, and an information domain control system. SAP is the enterprise's ERP system, managing business processes such as finance, supply chain, production, and human resources. PDM manages R&D data such as drawings, data, software, and configurations for product development. TSP is the Vehicle Service Platform, primarily responsible for data collection and supply between vehicles and various service providers, offering diverse services to car owners, including location services, navigation services, communication services, social services, entertainment services, remote maintenance services, and safety services. MES connects to the ERP system, converting order data generated by the ERP into production data related to the production process, including order numbers, order configurations, and the production BOM after workstation allocation. It also collects manufacturing process data in real time, achieving secondary data collection, closed-loop management, and monitoring of the production process, thus realizing production transparency and efficiency improvement.

[0030] based on Figure 1 The diagram shows the structure of a self-inspection control system for vehicle production and maintenance. This invention provides a detailed description of the self-inspection control method for vehicle production and maintenance. (See also...) Figure 2 The diagram shows a self-inspection and control method for vehicle production and maintenance. The method mainly includes the following steps S202 to S206:

[0031] Step S202: When the power supply to the ordered vehicle is detected, the information domain controller is connected to the vehicle's manufacturing execution system (MES) based on the key sent by the vehicle networking service platform. In one implementation, during system operation, after the market receives the order, it is entered and published in the order system. SAP obtains the order from the order system, including the order's delivery requirements, vehicle configuration information, and customer's special requirements. SAP matches the order vehicle's BOM and the software and component information used in the vehicle from the PDM according to data rules. After data generation, SAP outputs the data to the MES system. When vehicle production begins, the information domain controller automatically connects to the TSP platform after power-on. Through the TSP platform, it synchronizes with the production data in the ME. After synchronization, it automatically switches to the enterprise intranet VPN and begins downloading vehicle data, including software and function configurations, from the TSP.

[0032] Step S204: The vehicle information provided by the Manufacturing Execution System (MES) is sent to the Information Domain Controller (IDC). The IDC then performs a self-check to prevent errors in the vehicle's electronic control system based on the vehicle information. The vehicle information includes: vehicle configuration information, controller list and version, software version, flashing software list, software package, and electronic testing program. In one embodiment, after connecting the IDC to the vehicle's MES, the IDC needs to download the vehicle information from the MES. After downloading, the IDC begins a fault-prevention check of the vehicle's electronic control system. After the check, the IDC begins software flashing and parameter configuration operations. Order information can be obtained from the order system through the Enterprise Resource Planning (ERP) system. Based on the order information, data matching processing is performed on the automotive enterprise master data, software-related information, and component-related information in the Product Development Management System (PDM) to determine the vehicle information for the ordered vehicle. This vehicle information is then sent to the MES. The order information includes: order delivery requirements, vehicle configuration information, and customer requirements.

[0033] Step S206: After the vehicle's electronic control system passes the error-proofing self-test, the information domain controller is switched to production mode. Using an electronic inspection program and external cameras, a production self-test is performed on the vehicle's electronic control components and external equipment. This ensures that the ordered vehicles are delivered after the production self-test passes. In one implementation, after a vehicle rolls off the production line, the information terminal, with the assistance of an operator, inputs the operator's identity information and initiates an automatic vehicle inspection. Upon completion of the inspection, the data is uploaded to the TSP (Traffic Support Service). The TSP then transmits the error-proofing check, software write, and functional check logs from the information terminal to the MES (Manufacturing Execution System) for storage as production process data. Simultaneously, the TSP system synchronizes the production inspection results to the after-sales service system. When a user visits the after-sales service center, the system automatically sends the customer's after-sales service record back to the TSP. The TSP records these service records as part of the vehicle's full-lifecycle record in its database.

[0034] The self-inspection and control method for vehicle production and maintenance provided in this embodiment of the invention can significantly improve the accuracy and efficiency of fault detection during vehicle production and maintenance.

[0035] See Figure 3 The flowchart shown is a mode switching method for an information domain controller. This embodiment of the invention also provides an implementation method for controlling vehicle production, maintenance, and inspection, as detailed below (1) to (3):

[0036] (1) When the power of the ordered vehicle is detected to be turned on, the power-on command is sent to the information domain controller to start the information domain controller, so that the information domain controller can connect to the vehicle network service platform through the wireless network. Then, the key in the manufacturing execution system is encrypted by the vehicle network service platform and sent to the information domain controller, so that the information domain controller switches to VPN and connects to the manufacturing execution system. Specifically, when the vehicle is powered on, the information domain controller is turned on and works. The terminal connects to the vehicle network service platform through the wireless network. The vehicle network service platform encrypts the key received from the manufacturing execution system and sends it to the information domain controller. The information domain controller switches to VPN and connects to the manufacturing execution system. The vehicle configuration information, controller list and version, software version and flashing software list, software package, and electrical inspection specifications are downloaded from the manufacturing execution system.

[0037] (2) Based on the controller list and version, software version, flashing software list and software package, the information domain controller is flashed and parameter configured to register the order vehicle. By loading the factory network information, the information domain controller is switched to production mode. In one embodiment, video information of the order vehicle is collected by a set of external cameras, and the action of the vehicle's external equipment is determined by the action recognition processing of the video information. When the action of the vehicle's external equipment is consistent with the preset standard equipment action, and the test results of the electric inspection program for each vehicle's electronic control component are normal, the order vehicle is determined to have passed the production self-inspection. When the vehicle's production self-inspection fails, the test process data of the vehicle's electronic control component and the video information of the order vehicle are stored and recorded, and a site retest reminder message is sent to the quality inspector's terminal.

[0038] Specifically, when the system starts running the electrical inspection function, the electrical inspection operation needs to be performed according to the prompts on the information terminal. The information terminal, following the downloaded electrical inspection program, begins to check the vehicle's electrical and electronic control components item by item. Furthermore, it can be combined with operator operation and confirmation, so that the final electrical inspection results are double-checked based on the operator's confirmation and the data monitored by the information terminal. When inconsistencies are found, the data is uploaded to the on-site quality inspector for retesting and confirmation. See [link to relevant documentation]. Figure 4 The diagram shows a camera arrangement structure for an electrical inspection station. Cameras are installed on the front, rear, left, and right sides of the vehicle outside the station. When an electrical inspection is performed, the camera identifies the actions of external equipment such as lights, windows, and wipers, and transmits the identified actions to the manufacturing execution system.

[0039] (3) Track the vehicle status of the ordered vehicles in real time and switch the working mode of the information domain controller according to the vehicle status, as detailed in (A) to (C) below:

[0040] (A) When the log upload and network parameter initialization of the ordered vehicle are detected, the information domain controller is switched to the shipping mode. In one implementation, the data information generated by the ordered vehicle during the production self-inspection process is recorded as the production process log. When the production process log is uploaded to the manufacturing execution system, the vehicle information of the corresponding ordered vehicle is deleted from the manufacturing execution system, and the information domain controller is switched to the shipping mode. That is, after the vehicle is manufactured and inspected in the factory, the vehicle is moved to the delivery area. After delivery, the manufacturing execution system transmits the vehicle status to the information terminal. The information terminal performs the operation, uploads the production process log to the manufacturing execution system, clears the process data downloaded from the manufacturing execution system, and initializes the network parameters. The system switches from production mode to shipping mode.

[0041] (B) When it is detected that the ordered vehicle has been sold, switch the information domain controller to customer mode.

[0042] (C) When an ordered vehicle is detected entering a repair shop or a customer calls for roadside assistance, the information domain controller is switched to repair mode. In one implementation, production data from the production process log is retrieved and compared with the vehicle's current data to provide repair data support. That is, after a vehicle is sold to a user, the information terminal switches to user mode. When a customer enters a repair shop or calls for roadside assistance, on-site repair personnel or remote after-sales engineers log into their personal accounts, and the information terminal switches to repair mode. The repair engineer then uses the display screen to operate the vehicle. The information terminal can read production data and compare it with current data, providing data support for on-site and remote repairs.

[0043] In summary, this invention eliminates the need for functional testing and after-sales diagnostic instrument development during the early production and after-sales phases of a project, saving time and costs. It also avoids secondary development work required for later product upgrades. Furthermore, production and after-sales use the same equipment and data sources as development, avoiding data discrepancies caused by multiple development processes. Simultaneously, by utilizing information terminals, the entire production process data (including initial system state parameters) is recorded, providing original data support for after-sales maintenance, quickly locating fault points, and improving user experience.

[0044] Meanwhile, after the information terminal accesses the manufacturing execution system via VPN, it obtains the master data and software and hardware information of the production vehicles. Using electronic control diagnostic technology, it can compare and check the data of the vehicle's electronic control system in real time to achieve software and hardware error prevention. In addition, during the production process, image recognition technology is used to identify and record operators and operation results. In the electronic inspection operation, the electronic inspection process is proceduralized, making the electronic inspection process controllable and preventing omissions. Finally, this invention simplifies the enterprise information system, improves data flow efficiency, and improves the operation mode of traditional production methods that require multiple systems to operate in parallel.

[0045] Regarding the self-inspection control method for vehicle production and maintenance provided in the foregoing embodiments, this invention provides a self-inspection control device for vehicle production and maintenance.

The vehicle information includes: configuration information, controller list and version, software version, flashing software list, software package and electronic test program.

[0048] The vehicle self-inspection module 506 switches the information domain controller to production mode after the vehicle's electronic control system passes the error prevention self-inspection. It then uses the electronic inspection program and external camera set to perform production self-inspection on the vehicle's electronic control components and external equipment.
