At this time, because the data only flows in one direction, the dealer management system (DMS) at the post-sales end cannot obtain the original design data of the vehicle (such as hardware version, software dependency relationship, configuration rule, etc.) in the product lifecycle management system (PLM) at the research and development end, and the electrical inspection procedure also lacks configuration word matching logic, resulting in the function implementation of the add-on part having to rely on manual offline operation, which is inefficient and prone to errors.

DETAILED DESCRIPTION

[0017] In order to make the purposes, technical solutions and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that in the embodiments of the present application, many technical details are proposed in order to make the readers better understand the present application. However, even without these technical details and according to various changes and modifications of the following embodiments, the technical solutions claimed by the present application can be implemented. The following embodiments are divided for the convenience of description, and should not constitute any limitation on the specific implementation of the present application, and the embodiments can be combined and referred to each other without contradiction.

[0018] The existing reverse upgrade technology of the automobile industry for the sold vehicles refers to installing the add-on parts not belonging to the original vehicle design in the sold vehicles, and through the reverse upgrade installation, the function enhancement (such as intelligent driving hardware), compliance adaptation (such as emission modification) or differentiated service (such as subscription function unlocking) can be realized. However, this operation mainly depends on the independent management of the after-sales channel, and the research and development end and the after-sales end are completely separated, the after-sales end cannot reversely synchronize the add-on part configuration information to the research and development end, the vehicle has two independent data of “factory state” and “modified state”, which leads to the disconnection of the upgrade scheme and the original vehicle design data, for example, the over-the-air (OTA) upgrade package cannot identify the add-on part configuration, which leads to the upgrade failure, and the electrical inspection procedure is forced to rely on manual offline operation due to the lack of configuration word matching logic, at the same time, the after-sales end lacks the automatic detection process driven by the option code, which leads to quality risks and low modification efficiency. Based on the above problems, the present application provides a reverse upgrade method. Figure 1 The present application provides a reverse upgrade method, and the step flow chart of the method is shown in Figure 1. Step 101, in response to the user's option request for the vehicle add-on part in the dealer management system, an after-sales order about the vehicle to be modified is generated, and the after-sales order carries the characteristic configuration code about the vehicle add-on part previously issued by the product life cycle management system.

[0019] The dealer management system of the present application belongs to the after-sales end system, and the product life cycle management system belongs to the research and development end system. The current automobile industry generally adopts a one-way linear data flow mode of research and development → manufacturing → after-sales for the upgrade and maintenance of vehicles, which leads to the fact that the after-sales end cannot obtain the data of the research and development end when modifying the vehicle, thereby causing a series of problems. The present application creates a storage space for storing the characteristic configuration code of the add-on part and a storage space for storing the characteristic configuration bill of materials of the add-on part in the product life cycle management system of the research and development end, and simultaneously newly creates the characteristic configuration process data of the add-on part. The implementation steps include: Obtain several vehicle models that can be assembled with the add-on part; For any vehicle model, determine the target vehicle add-on part that can be selected and installed for the vehicle model, and establish the characteristic configuration code storage space, the characteristic configuration bill of materials storage space and the characteristic configuration process data space about the target vehicle add-on part in the product life cycle management system, wherein the characteristic configuration code storage space is used to store the characteristic configuration code of the target vehicle add-on part, the characteristic configuration bill of materials storage space is used to store the characteristic configuration bill of materials of the target vehicle add-on part, and the characteristic configuration process data space is used to store the characteristic configuration process data of the target vehicle add-on part; The vehicle model name of the vehicle model is acquired, and the vehicle model name and the preset characteristic fallback identifier are used to name the characteristic configuration code storage space, the characteristic configuration bill of material storage space, and the characteristic configuration process data space respectively.

[0020] In order to facilitate the distinction, the application sets different characteristic configuration code storage spaces, characteristic configuration bill of material storage spaces, and characteristic configuration process data spaces for different vehicles, and names them according to the vehicle model name, so as to facilitate the distinction of data of different vehicle models. Because the relevant data about the add-on parts are stored in these newly created storage spaces, in order to distinguish them from the original data of the vehicle, the application also adds a preset characteristic fallback identifier in the naming. For example, the vehicle model name is F2, and the preset characteristic fallback identifier is R, then the name of the characteristic configuration code storage space created for this vehicle model is "RF2", the name of the characteristic configuration bill of material storage space is "RF2", and the corresponding characteristic configuration process data space is named "RF2". If the vehicle model name is P3, then the name of the characteristic configuration code storage space created for this vehicle model is "RP3", the name of the characteristic configuration bill of material storage space is "RP3", and the corresponding characteristic configuration process data space is named "RP3". It should be understood that, because the access permissions, processing logic, and integration methods of different systems are different, the path isolation is needed to ensure the data security and system compatibility. This means that the storage paths of the characteristic configuration code space, the characteristic configuration bill of material space, and the characteristic configuration process data space are different, so even if the names of the three spaces are the same, because the storage paths are different, there will be no confusion in subsequent data acquisition.

[0021] By independently configuring the storage spaces, the risk of mixing the relevant data of the add-on parts with the original data of the vehicle is avoided from the source.

[0022] It should be understood that the types of the target vehicle add-on parts that can be selected and installed by the vehicle model will be dynamically updated with the progress of technology. When the types of the target vehicle add-on parts change, the corresponding characteristic configuration code, characteristic configuration bill of material, and characteristic configuration process data will also be dynamically updated. At present, the types of the target vehicle add-on parts that can be selected and installed by the vehicle model can be determined according to expert experience and historical installation data, and the corresponding characteristic configuration code, characteristic configuration bill of material, and characteristic configuration process data are determined according to the historical installation data, or are set by the product engineers according to the types of the target vehicle add-on parts. The application does not make specific limitations here.

[0023] The application sets code rules for the characteristic configuration code stored in the storage space after creating the characteristic configuration code storage space, facilitating fusion with the original code of the vehicle. The set code rules include setting the reserved value of the vehicle model code in the code to a specified value. In addition to setting the vehicle model code, the application also sets a mark and naming rule for the add-on package corresponding to the characteristic configuration code of the add-on. That is, the preset characteristic fallback identifier is also added to the original name of the add-on package, indicating that the configuration code in the add-on package is different from the configuration code of the original vehicle parts. Because there may be multiple characteristic configuration codes of add-ons in the characteristic configuration code storage space of one vehicle model, in order to distinguish them, an add-on type identifier is also added, and in order to make the staff on the research and development side clear that the vehicle parts do not belong to the original vehicle parts, but are add-on parts selected during after-sales modification, an after-sales identifier is also added. The steps include: Retrieving the characteristic configuration code in the characteristic configuration code storage space to obtain the vehicle model code, and pre-setting a reserved value in the vehicle model code; Modifying the reserved value of the vehicle model code to a specified value; For any target vehicle add-on corresponding add-on package, obtaining the add-on package name, adding a preset characteristic fallback identifier to the add-on package name, and adding an add-on type identifier and an after-sales identifier to the add-on package, the add-on package containing the characteristic configuration code of the target vehicle add-on.

[0024] For example, the original vehicle model code is B27FRF8JA4L01, the specified value is 2, the 13th bit is the reserved value, when the reserved value is 0, it indicates that the vehicle is a completely original vehicle produced according to the design of the research and development side, when the reserved value is 1, it indicates that the vehicle is a regionally supplied vehicle, and when the reserved value is 2, it indicates that the vehicle is a characteristic fallback vehicle containing an add-on. Therefore, the vehicle model code contained in the characteristic configuration code is changed to B27FRF8JA4L02. The research and development side can subsequently determine the vehicle type (whether containing an add-on) by detecting the value of the 13th bit. In addition, for the add-on package, if the original name is "P001-F2" and the add-on type is A01 type, it is changed to "P001-RF2", and then "A01" identifier and "after-sales" identifier are added. Among them, P001 is the storage level of the information in the system, and F2 is the original vehicle model name.

[0025] The above steps achieve precise digital management of non-native add-ons by dynamically modifying the reserved value of the vehicle model code and adding identifiers to the add-on package, which not only retains the traceability of the original factory vehicle model code, but also makes the code compilation rules used by the after-sales side and the research and development side consistent through unified code configuration, supporting compliant configuration, service subscription (such as function unlocking) and after-sales traceability of the vehicle in the reverse upgrade scenario.

[0026] The naming of the feature configuration code storage space and the code rules set for the feature configuration code contained therein are described in the above steps. The present application also newly creates a feature configuration bill of materials storage space, in which only the feature configuration bill of materials of the vehicle add-on part is stored. Because the feature configuration bill of materials storage space is named according to the vehicle model name and the preset feature fallback identifier, different feature configuration bill of materials storage spaces are set for different vehicle models. Each feature configuration bill of materials storage space stores the feature configuration bill of materials of the add-on part of the vehicle model. The feature configuration bill of materials includes the Engineering Bill of Materials (EBOM) of the add-on part of the vehicle model, the Manufacturing Bill of Materials (MBOM) of the add-on part of the vehicle model, and the material list of the nodes related only to the add-on part of the vehicle model in the architecture of the Sales Variant Programming Assembly Bill Of Materials (SVPABOM).

[0027] In addition, the present application also newly creates feature configuration process data for defining the exclusive assembly process requirements (such as station and production line information) of the add-on part. The data sources of the feature configuration process data are specified in the present application. First, it is necessary to determine whether the add-on part of a vehicle model is a component in other vehicle models. If yes, it is considered that the add-on part belongs to a borrowed part from other vehicles, in which case the process parameters of the corresponding vehicle can be directly called as the feature configuration process data of the add-on part. If not, the data freezing and release process needs to be independently performed for the add-on part, and then the product engineer provides the three-dimensional model after assembly, i.e., the experimental calibration process parameters, to determine the feature configuration process data through the two kinds of data, including the following steps: Obtaining the source information of the vehicle add-on part; Determining whether the vehicle add-on part is a borrowed part from the target vehicle through the source information; If it is a borrowed part from the target vehicle, obtaining the process parameters of the borrowed part in the target vehicle; If it is not a borrowed part from the target vehicle, obtaining the experimental calibration process parameters of the vehicle add-on part; Determining the feature configuration process data through the process parameters of the borrowed part in the target vehicle and the experimental calibration process parameters.

[0028] The above steps realize cross-model resource reuse and accurate process data adaptation by intelligently identifying the source of the add-on part (borrowed part or experimental calibration part) and dynamically matching the corresponding process parameters (original vehicle process or experimental data), which not only reduces the research and development cost of reverse upgrading (such as the original vehicle parameters directly inherited by the borrowed part), but also ensures the reliability of the non-standard add-on part (verified by experimental calibration process), finally generates high-compatibility characteristic configuration process data, and improves the modification efficiency and quality control level.

[0029] In addition to the above settings, the present application adds a project for storing vehicle add-on part related information of the vehicle to be modified in the design change process module to intercept potential compatibility conflicts, and forcibly associates the project with the original design change process project, and the implementation steps include: Obtain the design change process module of the vehicle to be modified, and the design change process module includes an original design change process project; Add a vehicle add-on part characteristic back-off project in the design change process module, and the vehicle add-on part characteristic back-off project is used to store vehicle add-on part related information of the vehicle to be modified; Forcibly associate the vehicle add-on part characteristic back-off project with the original design change process project, and control the original design change process project to make corresponding adjustments according to the changes of the vehicle add-on part characteristic back-off project.

[0030] The above steps realize the systematic cooperation of reverse modification and native design by modularizing the extension of the design change process (adding a characteristic back-off project) and forcibly associating the original process, which not only retains the standardized control of the original equipment manufacturer (Original Equipment Manufacturer, OEM) (such as safety verification), but also supports flexible after-market adaptation (such as dynamic parameter adjustment), thereby significantly improving modification efficiency and reducing engineering risk while ensuring vehicle compliance and consistency.

[0031] The above settings can intercept potential compatibility conflicts when reverse upgrading the vehicle to be modified through the target order and the electrical inspection configuration word. For example, if the original design change process project includes standard processes such as chassis structure, electrical system compatibility verification, etc. of the fuel vehicle, if the target order needs to insert a "battery pack add-on", at this time, the vehicle add-on part characteristic back-off project appears new information, which is to insert a "battery pack add-on" item in the change process, and records data such as battery model, high-voltage wiring harness modification process, etc. At this time, because the vehicle add-on part characteristic back-off project is forcibly associated with the original design change process project, when the battery pack parameters are changed (such as capacity upgrade), the original chassis load-bearing and heat dissipation system are automatically triggered for re-verification, ensuring modification safety.

[0032] The add-on package corresponding to the vehicle add-on part in the above step of the application adds an add-on part type identifier and an after-sales identifier. This identifier not only helps R&D personnel to distinguish the type of parts, but also can be used in the dealer management system for screening of parts. That is, in the dealer management system, the pre-sale identifier can be selected to display the original part type of the vehicle, and then the replacement and maintenance can be performed according to the demand. The after-sales identifier can also be selected to display the add-on part of the vehicle, and then the corresponding add-on part can be selected for installation according to the demand, and the steps include: In response to the selection operation of the after-sales identifier by the user in the dealer management system, the add-on page of the vehicle add-on part is displayed. In response to the add-on request of the vehicle add-on part by the user on the add-on page, the after-sales order about the vehicle to be modified is generated.

[0033] The above steps are triggered by the user's interaction with the after-sales identifier, automatically associate and display the adapted vehicle add-on part add-on page, simplify the selection process of the modification requirement; based on the user's add-on request, the after-sales order is generated one key, realizing the closed-loop automation from customer demand identification to service order creation, significantly improving the response efficiency of the dealer service and customer experience, while ensuring the accurate docking of the modification requirement and the structured retention of the order data.

[0034] It should be understood that only the after-sales order generated based on the add-on request of the add-on part needs to obtain relevant data from the feature configuration code storage space, the feature configuration bill of materials storage space and the feature configuration process data space of the product life cycle management system. If the vehicle original design part is updated and maintained, the corresponding part data is retained in the after-sales system, which can be directly obtained.

[0035] Step 102, according to the feature configuration code, extracting the feature configuration bill of materials and feature configuration process data pre-labeled for the vehicle add-on part from the product life cycle management system.

[0036] The present application generates a production order in the dealer management system after generating an after-sales order about a vehicle to be refitted, triggers a system, application and product (SAP) system / advanced planning and scheduling (APS) system to generate a production order according to the after-sales order, adds an interface to rebroadcast the production order to other interface systems (such as a logistics material sequencing (LMS) system, a manufacturing operations management (MOM) system, a dealer management system and a vehicle cloud system), and the like). At this time, the information carried in the production order and the after-sales order is basically the same, except that the generated systems are different.

[0037] Then, the logistics material sequencing system extracts the pre-labeled configuration material list for the vehicle accessory from the configuration material list storage space of the product lifecycle management system based on the configuration code in the production order, and the manufacturing operations management system extracts the corresponding configuration process data from the configuration process data of the product lifecycle management system based on the configuration code in the production order. The configuration process data can support process requirements such as pass point information, critical part binding, quality gate control and loading single printing.

[0038] Step 103, obtaining the original vehicle order of the vehicle to be refitted.

[0039] In the present application, the original vehicle order of the vehicle is obtained according to the vehicle identification number (VIN), which is equivalent to the "identity card number" of the vehicle, one vehicle one code, lifelong unchanged, so the vehicle identification number and the original vehicle order are bound, which can uniquely identify the original vehicle order of the current vehicle, avoiding confusion with the original vehicle order of different vehicles. Then the original vehicle order of the vehicle is obtained through the vehicle identification number.

[0040] Among them, the original vehicle order may include the configuration code of the original vehicle design, the configuration process data and the configuration material list, in addition to which, the original vehicle order may also include the type information of the components configured in the vehicle, such as the engine, transmission, chassis, etc. by default configuration when the vehicle is shipped, production and logistics data information, such as factory information for producing the vehicle, transportation mode, destination dealer information, software and electronic file information, such as car system, ECU firmware initial version number, etc.

[0041] Step 104, generating a target order through the characteristic configuration code, the characteristic configuration bill of materials, the characteristic configuration process data and the original whole vehicle order.

[0042] The characteristic configuration bill of materials of the application defines the parts required for modification (such as adding battery packs, wiring harnesses, etc.), and the characteristic configuration process data provides modification process parameters (such as torque standards, wiring harness plug-in sequences), which correspond one-to-one with the materials in the characteristic configuration bill of materials.

[0043] When generating the target order, the original whole vehicle order and the characteristic configuration code, the characteristic configuration bill of materials and the characteristic configuration process data are integrated. When integrating, the characteristic configuration code is matched or extended with the original factory configuration code in the order. For the characteristic configuration bill of materials, conflict detection is required. When performing conflict detection, first determine whether there is a material of the same type in the characteristic configuration bill of materials as in the original whole vehicle order, if there is, select the cover conflict item, for example, the original order contains "low-end audio", and the parts required for modification contain "high-end audio", then mark it as covered and update the corresponding configuration code. Then check whether the materials in the modified characteristic configuration bill of materials conflict with the original factory configuration, such as adding a battery pack to a fuel vehicle, which requires verification of the chassis space, if there is no conflict, the characteristic configuration bill of materials does not need to be changed, if there is a conflict, send a prompt to replace other materials. For the characteristic configuration process data, adaptive adjustment is required according to the changes in the characteristic configuration bill of materials. The application does not make specific limitations here.

[0044] Step 105, generating the electrical inspection configuration word of the target order through the electrical configuration code system.

[0045] The application inputs the target order into the electrical configuration code system, and generates the electrical inspection configuration word of the target order through the electrical configuration code system. The electrical inspection configuration word is generated based on four pieces of configuration information. The four pieces of configuration information are vehicle model code, interior configuration code, exterior configuration code and option package configuration code. When the target order generates the electrical inspection configuration word, it inherits the configuration word defined by the original vehicle (to ensure compatibility of basic functions), dynamically combines the unique configuration word generated based on the characteristics of the added parts (such as special functions, regulatory requirements or differentiated design) with the original configuration word, and finally outputs a new electrical inspection configuration word that can both be compatible with the original vehicle and meet the characteristics of the added parts.

[0046] The unique configuration word generated based on the characteristics of the added parts also uses the four pieces of configuration information, but modifies the reserved value of the vehicle model code to a specified value, and uses the characteristic configuration code of the added parts for the option package configuration code.

[0047] For example, Figure 2As shown, in the PF2MBOM1001 node, in the subsystem of the electrical configuration code system, the numbered UA01 node stores the characteristic materials Part01, Part02 and Part03 of the add-on, wherein the unique configuration word generated based on the characteristics of the add-on exists in this node. The four segments of configuration information include a new basic configuration vehicle model code, interior decoration (PA00=PA84), exterior decoration (CC00=CC12) and an optional package (P001-RF2). The difference between the new basic configuration vehicle model code "B27FRF8IA4L02" and the old basic configuration vehicle model code "B27FRF8IA4L01" is that the 13th reserved value of the new basic configuration vehicle model code is replaced by "2".

[0048] In step 106, the vehicle add-on is added to the vehicle to be modified through the target order and the electrical inspection configuration word, so as to realize the reverse upgrade of the vehicle to be modified.
