DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] At present, relevant technologies have proposed that during the vehicle production process, the production line needs 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 program and electrically inspect the vehicle. In addition, after-sales diagnostic equipment needs to be developed, and each maintenance station needs to be equipped with at least one diagnostic device for daily maintenance use. 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 prolongs the inspection cycle, reduces inspection efficiency, and increases development costs. In addition, due to differences in equipment and data sources used in production and after-sales, multiple developments will lead to data deviations, thereby reducing the accuracy of production and maintenance inspections. With the development of Internet of Vehicles technology, car companies have developed remote vehicle control, diagnosis, and OTA (i.e., functional testing for vehicle production), sales After-sales service uses a diagnostic instrument, while the car company's remote service uses the Internet of Vehicles service platform and remote terminal. The above three areas have overlapping content in technology, and the current vehicle electrical architecture is mainly developing towards the domain control field. The controller has very strong computing power, and there are also multiple networking methods on the vehicle, including CAN\WIFI\Ethernet\4G\5G, etc. Based on this, the self-inspection control method, device and server for vehicle production and maintenance provided by the present invention can eliminate the diagnostic equipment used in traditional production and after-sales. From production to after-sales maintenance after delivery to users, all rely on the information domain controller. In the process of vehicle offline electrical inspection and after-sales service, image recognition and Internet of Vehicles technology are used to realize production error prevention control, vehicle configuration data control and software version control, which can significantly improve the accuracy and efficiency of fault detection in the process of vehicle production and maintenance.

[0023] To facilitate understanding of this embodiment, a vehicle production and maintenance self-inspection control method disclosed in an embodiment of the present invention is first described in detail. The 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, an embodiment of the present invention provides a structural schematic diagram of a vehicle production and maintenance self-inspection control system, as shown in FIG. Figure 1 As shown, it includes: an order system, an enterprise resource management system (SAP), a product development management system (PDM), a manufacturing execution system (MES), a connected vehicle service platform (TSP), an after-sales service system, and an information domain control system. SAP is the enterprise's ERP system (i.e., enterprise resource planning system), which manages the company's financial, supply chain, production, human resources, and other business processes. PDM is the product development management system, which manages product development data such as drawings, data, software, and configurations. TSP is the connected vehicle service platform, which is primarily responsible for data collection and supply between cars and various service providers, providing car owners with a variety of services, including location services, navigation services, communication services, social services, entertainment services, remote maintenance services, and safety services. MES is connected to the ERP (i.e., enterprise resource planning system) to convert order data generated by ERP into production data related to the production process, including order numbers, order configurations, and the production bill of materials after workstation allocation. It also collects manufacturing process data in real time, enabling multiple collection, closed-loop monitoring, and production process data, achieving production transparency and efficiency improvement.

[0024] based on Figure 1 The structure diagram of the self-check control system of vehicle production and maintenance is shown in FIG. The embodiment of the present invention introduces the self-check control method of vehicle production and maintenance in detail. Figure 2 The flowchart of a self-check control method for vehicle production and maintenance is shown, and the method mainly includes the following steps S202 to S206: Step S202, when it is detected that the power of the ordered vehicle is turned on, the information domain controller is connected to the vehicle's production and manufacturing execution system based on the key sent by the Internet of Vehicles service platform. In one embodiment, when the system is running, after the market receives the order, it is entered and released in the order system, and SAP obtains the order from the order system, including the delivery requirements of the order, vehicle configuration information, customer's special requirements, etc. Based on the data rules, SAP matches the BOM of the ordered vehicle and the software and parts information used in the vehicle from the PDM. After completing the data generation, SAP outputs the data to the MES system. When the vehicle starts production, the information domain controller automatically connects to the TSP platform after powering on, and synchronizes with the production data in the ME through the TSP platform. After synchronization, it automatically switches to the enterprise intranet VPN and starts downloading data for the vehicle from the TSP, including software and function configuration.

[0025] In step S204, the vehicle information provided by the manufacturing execution system is sent to the information domain controller, so that the information domain controller performs error-proofing self-inspection processing on 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 electrical inspection program. In one embodiment, after the information domain controller is connected to the vehicle's manufacturing execution system, it is necessary to download the vehicle information from the manufacturing execution system. After downloading, the information terminal starts to perform error-proofing inspection on the vehicle's electronic control system. After the inspection, the information terminal starts to perform software flashing and parameter configuration operations. The order information in the order system can be obtained through the enterprise resource management system, and then the automobile enterprise master data information, software-related information and component-related information in the product R&D management system are matched according to the order information to determine the vehicle information of the order vehicle, and send the vehicle information to the manufacturing execution system, wherein the order information includes: delivery requirement information of the order, vehicle configuration information and customer requirement information.

[0026] In 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 the electrical inspection program and a collection of peripheral cameras, the vehicle's electronic control components and external equipment are subjected to production self-inspection. This allows the ordered vehicle to be delivered after the vehicle passes the production self-inspection. In one embodiment, after the vehicle rolls off the production line, the information terminal, with the assistance of the operator, inputs the operator's identity information and initiates an automatic inspection of the vehicle. Upon completion of the inspection, the information terminal uploads the information to the TSP, which then passes the error-proofing inspection, software flashing, and functional inspection logs on the information terminal to the MES for storage as production process data. Simultaneously, the TSP system synchronizes the results of the production inspection to the after-sales service system. When a user visits the after-sales service center for service, the system automatically transmits the customer's after-sales service record back to the TSP. The TSP records the service record as a full-cycle record of the vehicle in its database.

[0027] The self-check control method for vehicle production and maintenance provided by the embodiment of the present invention can significantly improve the accuracy and efficiency of fault detection during vehicle production and maintenance.

[0028] See also Figure 3 The flowchart of a mode conversion method of an information domain controller is shown. The embodiment of the present invention also provides an implementation method for controlling vehicle production maintenance inspection. For details, see (1) to (3) below: (1) When it is detected that the power of the ordered vehicle is connected, the information domain controller is started by sending a power-on command to the information domain controller, so that the information domain controller is connected to the Internet of Vehicles service platform through the wireless network. Then, the key in the production and manufacturing execution system is encrypted by the Internet of Vehicles service platform and sent to the information domain controller, so that the information domain controller switches to the VPN and connects to the production and manufacturing execution system. Specifically, when the vehicle is connected to the power, the information domain controller starts working, and the terminal connects to the Internet of Vehicles service platform through the wireless network. The Internet of Vehicles service platform encrypts the key received from the production and manufacturing execution system and sends it to the information domain controller. The information domain controller switches to the VPN and connects to the production and manufacturing execution system, and downloads the vehicle's configuration information, controller list and version, software version and flashing software list, software package, and electrical inspection specifications from the production and manufacturing execution system.

[0029] (2) According to the controller list and version, software version, flash software list and software package, the information domain controller is flashed and parameter configuration is processed to record the ordered vehicle, and the information domain controller is switched to production mode by loading the factory network information. In one embodiment, the video information of the ordered vehicle is collected by a set of peripheral cameras, and the action of the vehicle's external equipment is determined by performing motion recognition processing on the video information. When the vehicle external equipment action corresponding to each external equipment of the ordered vehicle is consistent with the preset standard equipment action, and the electric inspection program has normal test results for each vehicle electronic control component, it is determined that the ordered vehicle has passed the production self-inspection. When the vehicle production self-inspection fails, the inspection process data of the vehicle electronic control components and the video information of the ordered vehicle are stored and recorded, and a site retest reminder message is sent to the quality inspector terminal.

[0030] Specifically, when the system starts to run the electrical inspection function, it is necessary to perform the electrical inspection operation according to the prompts of the information terminal. The information terminal starts to check the vehicle's electrical and electronic control components item by item according to the downloaded electrical inspection program. In addition, the operator can also perform operations and confirmations, so that the final electrical inspection structure is double-compared based on the operator's confirmation and the data monitored by the information terminal. If there is any inconsistency, it will be uploaded to the on-site quality inspector for re-testing and confirmation. See Figure 4 The figure shows a schematic diagram of the camera arrangement structure of an electrical inspection station. Cameras are installed outside the station at the front, rear, left and right sides of the vehicle. When performing electrical inspection operations, the actions of external devices such as external lamps, windows, wipers, etc. are identified and the identified actions are transmitted to the production execution system.

[0031] (3) Track the vehicle status of the ordered vehicle in real time and switch the working mode of the information domain controller according to the vehicle status. For details, see (A) to (C) below: (A) When it is monitored that the order vehicle has completed log uploading and network parameter initialization, the information domain controller is switched to the shipping mode. In one embodiment, the data information generated by the order vehicle during the production self-inspection process is recorded as a production process log. When the production process log is uploaded to the production and manufacturing execution system, the vehicle information corresponding to the order vehicle is deleted from the production and manufacturing execution system, and the information domain controller is switched to the shipping mode. That is to say, after the vehicle is manufactured and inspected in the factory, the vehicle is transported to the delivery area, and after delivery, the production and manufacturing execution system transmits the vehicle status to the information terminal. The information terminal performs the operation, uploads the production process log to the production and manufacturing execution system, clears the process data downloaded from the production and manufacturing execution system, and initializes the network parameters. The system is switched from production mode to shipping mode.

[0032] (B) When it is detected that the ordered vehicle has been sold, the information domain controller is switched to customer mode.

[0033] (C) When an ordered vehicle is detected entering a repair station or a customer calls for assistance, the information domain controller switches to maintenance mode. In one embodiment, production data from the production process log is retrieved and compared with the vehicle's current data to provide maintenance data support. That is, after the vehicle is sold to the user, the information terminal switches to user mode. When the customer enters the repair station for maintenance or calls for assistance, the on-site maintenance personnel or remote after-sales engineer logs into their personal account, and the information terminal switches to maintenance mode. The maintenance engineer uses the display screen to operate and repair the vehicle. The information terminal can read production data and compare it with current data, providing data support for on-site and remote maintenance.

[0034] In summary, the present invention eliminates the functional testing and after-sales diagnostic instrument development work in the early production and after-sales stages of the project, saving time and costs, and also avoiding the secondary development work brought about by later product upgrades. Moreover, the same equipment and data sources are used for production and after-sales use and development, avoiding data deviations caused by multiple developments. At the same time, the entire production process data (including the system initial state parameters) is recorded using information terminals to provide original data support for after-sales maintenance, quickly locate fault points, and improve user experience.

[0035] At the same time, after the information terminal is connected to the production and manufacturing execution system through VPN, the master data, software and hardware information of the production vehicles are obtained. By using electronic control diagnostic technology, the vehicle electronic control system data can be compared and checked 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. During the electrical inspection operation, the electrical inspection process is programmed to make the electrical inspection process controllable and avoid missing items. Finally, the present invention simplifies the enterprise information system, improves the data flow efficiency, and improves the traditional production method that requires multiple systems to operate in parallel.

[0036] Regarding the vehicle production and maintenance self-checking control method provided in the above embodiment, an embodiment of the present invention provides a vehicle production and maintenance self-checking control device, which is applied to the vehicle production and maintenance self-checking control system, see Figure 5 The structure diagram of a self-check control device for vehicle production and maintenance is shown, and the device includes the following parts: The platform communication module 502 connects the information domain controller to the vehicle's manufacturing execution system based on the key sent by the Internet of Vehicles service platform when it detects that the ordered vehicle is powered on.

The vehicle information includes configuration information, controller list and version, software version, flash software list, software package, and electronic test procedures. The vehicle self-inspection module 506 switches the information domain controller to the production mode after the vehicle electronic control system passes the anti-error self-inspection, and uses the electric inspection program and the peripheral camera set to perform production self-inspection processing on the vehicle electronic control components and the vehicle external equipment operations, so as to deliver the ordered vehicle after the vehicle production self-inspection passes.
