Description

Technical Field

[0001] The present application relates to the technical field of vehicle design, and in particular to a vehicle design collaborative calculation and verification management system and method. Background Art

[0002] At present, in the design and development stage of vehicle model projects in the vehicle industry, a vehicle model project is usually decomposed into the overall layout of the vehicle model, electrical system, power system, steering system, braking system, suspension system, body system, etc., and multi-professional, multi-department, and multi-level personnel are collaboratively designed. During the collaborative calculation and verification of the design scheme, most professionals use the method of typing formulas or templates in Excel tables to perform design and verification calculations. The specific problems are as follows:

[0003] 1. The calculation tables are not highly correlated with vehicle design, and the efficiency of collaborative work among different disciplines is low.

[0004] Due to the complexity of vehicle project, there are many formulas, calculation tables, charts, etc. involved. For example, for a certain vehicle design, about 63 tables are required, and 312 verification and calculation formulas are required. The extensive use of Excel tables makes the collaborative verification and calculation of design solutions not highly relevant to the currently developed vehicle models. There are a large number of parameters in each discipline that cannot directly call the mature data of the developed vehicle models. They need to be manually entered frequently in different calculation tables, and the verification and approval links are repeatedly calculated, resulting in low work efficiency and a high input error rate. At the same time, if the new adaptive development project calls the results of the reference vehicle project design calculation, there will be many inconveniences.

[0005] 2. The efficiency of public parameter sharing is low; the management of design change versions is chaotic.

[0006] Each discipline and designer designs, calculates, and verifies on their own, forming data islands. Public parameters are transmitted and shared through WeChat, QQ, email, etc., and the accuracy of the data cannot be guaranteed. The boundaries or disciplines affected by design changes are difficult to define accurately, and the accuracy of the changed versions needs to be confirmed repeatedly. Design quality problems caused by unsynchronized design changes often occur.

[0007] 3. Data management is decentralized, making modularization difficult.

[0008] During the years of vehicle project design and development, each discipline will arrange dedicated personnel to gradually summarize the verification and calculation results of each project to form an independent database or component model library established by each discipline. Due to the large number of disciplines involved and the company's organizational structure planning, each professional belongs to multiple different departments, resulting in the decentralization of the corresponding vehicle model verification and calculation process data, and the lack of unified planning of the design verification database; at the same time, it also makes it difficult to implement modular management of each discipline, and the variety and model spectrum of products and components have expanded disorderly.

[0009] 4. The verification and calculation of design standards and specifications are not synchronized with the design scheme, and there is a lack of efficient support tools.

[0010] The design standards in the vehicle industry and the standards, specifications, and anti-recurrence data formed within each company are generally carried in scattered texts. During the verification and calculation of design schemes, most rely on the design experience of technicians to achieve verification or determination. It is difficult to synchronize the design standards and specifications with the verification and calculation of design schemes, and there are often situations of inaccurate verification or missing items. At the same time, because the amount of data such as standards, specifications, and anti-recurrence data involved in vehicle model projects is large, the verification efficiency is very low by relying on manual methods.

[0011] In summary, in the current design and development stage of vehicle model projects in the commercial vehicle industry, a vehicle model project is usually decomposed into multiple professionals, multiple departments, and multi-level personnel for collaborative design. During the collaborative verification and calculation of design schemes, most use the method of entering formulas or templates in Excel sheets for design and verification calculations, resulting in prominent problems such as low collaborative efficiency, low accuracy, version chaos, disconnection of design standards, and difficulty in implementing module management. Summary of the Invention

[0012] Aiming at the defects existing in the prior art, the purpose of this application is to provide a vehicle design collaborative calculation and verification management system and method, which unifies the format of design templates for different vehicle configurations under different vehicle families, and improves the efficiency and accuracy of vehicle design collaborative calculation and verification management based on the design templates.

[0013] To achieve the above objectives, the technical solutions adopted are as follows:

[0014] The first aspect of this application provides a vehicle design collaborative calculation and verification management system, including:

[0015] A vehicle model management module, which is used to configure design templates for different vehicle families. The design template includes multiple parameter items for components and their design prompt information. For parameter items with a sharing relationship, when the parameter item with design permission changes, other parameter items without design permission change synchronously; the design prompt information is used to provide design prompts for users when filling in parameter items; the vehicle model management module is also used to store design templates for different vehicle models during the iteration of vehicle models in the same vehicle family, and mark the parameter items that have changed in the latest vehicle model compared with the previous vehicle model in the design template;

[0016] A task assignment module, which is used to retrieve the corresponding design template according to the vehicle model development task book and assign the design permission of parameter items to the corresponding designers;

[0017] A design module, which is used to provide designers with access to design templates and fill them in; for parameter items that have not changed, the corresponding parameter values of the previous vehicle model are retrieved and filled in, and for parameter items that have changed, they are filled in in combination with design prompt information.

[0018] A verification module, which is used to configure a verification process for parameter items that have not changed and verify them.

[0019] In some embodiments, the design template includes design modules for all design blocks of the whole vehicle. Each design module includes parameter items for all components of the design block. Design permissions are configured for components shared by multiple design blocks in the design template. When the parameter items with design permissions change, other parameter items without design permissions change synchronously.

[0020] In some embodiments, the design prompt information includes design standards, parameter selection bases, anti-recurrence data, and component type spectrum data.

[0021] In some embodiments, the design module is further used to obtain the parameter items of all components in the design block for calculation, and judge whether the overall parameter value of the design block is the same as the existing component type spectrum data according to the calculation result. If so, all parameter items of the design block are marked as unchanged, and if not, all parameter items of the design block are marked as changed.

[0022] In some embodiments, the vehicle model management module is further used to configure calculation formulas and their value ranges for parameter items with an associated relationship;

[0023] The design module is further used to judge whether the values of all relevant parameter items are within the value range according to the calculation formula after the user fills in the parameter items. If not, an alarm message is output.

[0024] In some embodiments, the design template includes a two-dimensional analysis model and charts;

[0025] The design module is further used to automatically and real-time output the corresponding two-dimensional analysis model or chart after the user fills in the parameter items.

[0026] In some embodiments, the task assignment module is further used to store information of all designers in all design departments. The designer information includes information on personnel on duty, personnel qualifications, work load, and task completion accuracy information;

[0027] The task assignment module assigns the design tasks of the design block to the corresponding design department according to the designer information, and assigns the parameter item design permissions of the corresponding design module in the design template to the corresponding designers in the design department.

[0028] In some embodiments, the design module is further configured to record and save in real time the design information of all designers, and form a visual progress chart.

[0029] In some embodiments, the verification module is further configured to configure different levels of verification processes according to the difficulty level of the vehicle model development task.

[0030] A collaborative calculation and verification management method for vehicle design includes:

[0031] Configuring design templates for different vehicle families, where the design templates include multiple parameter items for components and their design prompt information. For parameter items with a sharing relationship, when a parameter item with design authority changes, other parameter items without design authority change synchronously; the design prompt information is used to provide design prompts for users when filling in parameter items; during the iteration process of vehicle models in the same vehicle family, store the design templates for different vehicle models, and mark the parameter items in the design templates that have changed in the latest vehicle model compared to the previous vehicle model;

[0032] Retrieve the corresponding design template according to the vehicle model development task book, and assign the design authority of the parameter items to the corresponding designers;

[0033] Designers retrieve the design template and fill it in; for parameter items that have not changed, retrieve the corresponding parameter values of the previous vehicle model for filling, and for parameter items that have changed, fill them in combination with the design prompt information;

[0034] Configure a verification process for parameter items that have not changed and verify them.

[0035] The beneficial effects brought by the technical solution provided by this application include:

[0036] Configure design templates with a unified format for different vehicle models under different vehicle families. The vehicle design and verification are both carried out based on the design templates with a unified format. Compared with the existing design calculation and development mode based on Excel in each design department, the development efficiency and accuracy are improved.

[0037] Configure multiple parameter items for vehicle components in the design template, and configure design prompt information for each parameter item. According to the existing design team, decompose the design tasks to obtain the design tasks of each design department and its subordinate designers. By configuring the design authority of the parameter items related to the design tasks, when designers obtain the design template for design, they only need to fill in the parameter items with design authority and refer to the pre-configured design prompt information when filling. The design prompt information can be industry standards, design bases or experience summaries, etc., so as to achieve the implementation of standards and specifications, and the design verification accuracy rate of new product development reaches 100%, and the problems in the ET (Engineering Trial) stage of vehicle model projects are significantly reduced.

[0038] For the parameter items shared by different vehicle models, the design permission can be configured only once. When the parameter items with design permission change, the other parameter items without design permission will change synchronously, greatly reducing the use of communication tools such as emails, WeChat, QQ, Feishu, and text messages, and effectively avoiding the phenomenon of multiple, multi-source, and scattered information input.

[0039] During the iterative process of different vehicle models in the same vehicle family, mark the change points in the design template of the latest version of the vehicle model relative to the previous version. When designers obtain the design template for design, they can directly retrieve the existing design for the unchanged parts and manually fill in the changed parts to achieve modular design and improve design efficiency. When performing design verification, only the changed parts need to be verified, improving the verification efficiency. Brief Description of the Drawings

[0040] Figure 1 It is a schematic diagram of the functional modules of the vehicle design collaborative calculation and verification management system in the embodiment of the present invention.

[0041] Figure 2 It is a flowchart of the vehicle design collaborative calculation and verification management method in the embodiment of the present invention. Detailed Embodiment

[0042] There is currently no dedicated vehicle design collaborative calculation and verification management tool in the commercial vehicle industry. Most companies generally use the method of embedding formulas in scattered Excel sheets to achieve verification and calculation, with extremely low collaborative efficiency. Some companies use the PDM (Product Data Management) system to manage the verification and calculation data of design schemes, but there are problems such as the need for technical personnel to manually fill in and review twice, cumbersome operations, low retrieval and management efficiency, difficulty in sharing public parameters, and disconnection between design standards and verification processes.

[0043] The following further describes the present application in detail with reference to the drawings and embodiments.

[0044] An embodiment of the present invention provides a vehicle design collaborative calculation and verification management system and method, which relates to the technical field of vehicle design. It includes configuring design templates for different vehicle families. For parameter items with a sharing relationship, when the parameter item with design authority changes, other parameter items without design authority change synchronously. Mark the parameter items in the design template that have changed in the latest vehicle model compared to the previous vehicle model. Retrieve the corresponding design template according to the vehicle model development task book, and assign the design authority of the parameter items to the corresponding designers. For the unchanged parameter items, retrieve the corresponding parameter values of the previous vehicle model for filling, and for the changed parameter items, fill them in combination with the design prompt information. Configure a verification process for the unchanged parameter items. The present invention configures a unified format of design templates for different vehicle models under different vehicle families, and improves the efficiency and accuracy of vehicle design collaborative calculation and verification management based on the design templates.

[0045] In a specific embodiment, as Figure 1 shown, the vehicle design collaborative calculation and verification management system includes:

[0046] A vehicle model management module, which is used to configure design templates for different vehicle families. The design template includes multiple parameter items for components and their design prompt information. For parameter items with a sharing relationship, when the parameter item with design authority changes, other parameter items without design authority change synchronously. The design prompt information is used to provide design prompts for users when filling in the parameter items. The vehicle model management module is also used to store design templates for different vehicle models during the vehicle model iteration process in the same vehicle family, and mark the parameter items in the design template that have changed in the latest vehicle model compared to the previous vehicle model.

[0047] Specifically, the vehicle model management module unifies information sources such as parameter entry, standard specifications, and design verification, and the cross-departmental collaboration caliber from the source of the vehicle model development task, and forms a design template. According to the vehicle model series and sub-markets, the vehicle model projects are divided into 4 major series including the traction series, cargo-carrying series, dump series, and special series, with 58 types of sub-market vehicle models to form a vehicle model management tree. For each sub-market vehicle model, a customized design template is associated, which improves the efficiency of subsequent vehicle model borrowing and retrieval. The identification of vehicle model change points enables professional designers to quickly identify, mark, and transfer the change points of the currently developed vehicle model relative to the basic vehicle model. On this basis, it supports designers to load the design and development plan of the basic vehicle model, and at the same time efficiently focus on the design plan of the change points, realizing the reuse of design plans and modules.

[0048] Furthermore, each approval link only needs to review the correctness of the design plan corresponding to the change points, which greatly reduces the workload of each approval link and the accuracy of approval.

[0049] Furthermore, customize search keywords, report types, statistical dimensions, etc. according to the needs of each specialty, support the rapid generation of various types of statistical analysis and reports for reporting requirements at all levels, greatly simplify the workload of statistical analysis and report production based on EXCEL spreadsheets in the past, further reduce the interfaces of full-time and part-time personnel in each department, and also provide an efficient tool for managers to understand relevant data such as the efficiency, quality, and progress of vehicle model task development from a macro perspective within a certain period of time.

[0050] The task allocation module is used to retrieve the corresponding design template according to the vehicle model development task book and allocate the design authority of the parameter items to the corresponding designers.

[0051] Specifically, through the vehicle model development task decomposition interface, share the current vehicle model configuration and vehicle model definition information, and unify the interface for information input. Furthermore, support the vehicle model person in charge to quickly decompose the current development task to professional designers in various fields such as vehicle model general layout, electrical system, power system, transmission system, steering system, braking system, suspension system, and body system, and clarify the division of labor of the design and development team.

[0052] The design module is used to provide designers with the ability to retrieve design templates and fill them in. For parameter items that have not changed, retrieve the corresponding parameter values of the previous vehicle model for filling. For parameter items that have changed, fill them in combination with design prompt information.

[0053] The verification module is used to configure the verification process for parameter items that have not changed and perform verification.

[0054] Specifically, based on the work scenarios of managers at all departments and levels, optimize the transfer and review process of the design scheme, reduce the intermediate data transfer links, and clearly define the functions and responsibilities of each link. Increase the arbitration mechanism for unclear main responsibilities of cross-professional designs and difficult problems, effectively reduce the types of meetings in various links including design definition, design scheme, and design review (here, the approval process and arbitration mechanism need to be sorted out and confirmed specifically based on the business level, business content, departments involved, etc.), greatly compress the meeting time of a single meeting, the participants, etc.

[0055] In this embodiment, design templates with a unified format are used for different vehicle model configurations under different vehicle families. The whole vehicle design and verification are both carried out based on the design template with a unified format. Compared with the existing design calculation and development mode based on Excel in each design department, the development efficiency and accuracy are improved.

[0056] Configure multiple parameter items for vehicle parts in the design template, and configure design prompt information for each parameter item. According to the existing design team, decompose the design tasks to obtain the design tasks of each design department and its subordinate designers. By configuring the design permissions of the parameter items related to the design tasks, when designers obtain the design template for design, they only need to fill in the parameter items with design permissions and refer to the pre-configured design prompt information when filling in. This design prompt information can be industry standards, design bases, or summary of experience, etc., so as to achieve the implementation of standards and specifications, and the design verification accuracy rate of new product development reaches 100%. The problems in the ET (Engineering Trial, engineering commissioning - design verification stage) of vehicle models are significantly reduced.

[0057] For parameter items shared by different vehicle parts, the design permissions can be configured only once. When the parameter items with design permissions change, other parameter items without design permissions will change synchronously, greatly reducing the use of communication tools such as emails, WeChat, QQ, Feishu, and text messages, and effectively avoiding the phenomenon of scattered information input from multiple sources.

[0058] During the iterative process of different models in the same vehicle family, mark the change points in the design template of the latest version model relative to the previous version model. When designers obtain the design template for design, they can directly retrieve the existing design for the unchanged parts and manually fill in the changed parts to achieve modular design and improve design efficiency. When performing design verification, only the changed parts need to be verified, improving the verification efficiency.

[0059] In a preferred embodiment, the design template includes design modules for all design blocks of the vehicle. Each design module includes parameter items for all parts of the design block. The design permissions are configured for the parts shared by multiple design blocks in the design template. When the parameter items with design permissions change, other parameter items without design permissions will change synchronously.

[0060] Specifically, by defining the common parameters of various specialties such as vehicle general layout, electrical system, power system, transmission system, steering system, braking system, suspension system, and body system, sorting out the input boundaries of each common parameter and establishing a data sharing mechanism, the parameters and calculation results of each specialty can be cross-checked. At the same time, the effect of sharing the input of common parameters by one specialty without repeated input by other relevant specialties is achieved. (The shared parameters can be used across specialties, which not only avoids the errors and omissions of repeated input and multi-channel input, but also forms cross-specialty cross-checking) Thus, the current vehicle model design and development team forms a strong association, avoiding the formation of data islands for the design calculations and verification results of each specialty and designers. At the same time, it also changes the inefficient mode of sharing public parameters through methods such as WeChat, QQ, and emails, effectively improving design efficiency and accuracy.

[0061] The design prompt information includes design standards, basis for parameter selection, anti-recurrence data, and component type spectrum data.

[0062] Specifically, the design standards, basis for parameter selection (annotations, explanations of design standards, telling designers how to select parameter values), anti-recurrence data, component type spectrum data (limited selectable data), etc. are associated with the design parameters one by one. The basis for parameter selection and anti-recurrence data are prominently displayed near the design parameters, effectively integrating the isolated development experience, avoiding the inefficiency, errors, and omissions of the Excel inspection templates for each specialty, and at the same time greatly improving the precipitation and reuse of design and development knowledge.

[0063] In a preferred embodiment, the design module is further configured to obtain the parameter items of all components in the design block for calculation, and determine whether the overall parameter value of the design block is the same as the existing component type spectrum data according to the calculation result. If so, mark all the parameter items of the design block as unchanged; if not, mark all the parameter items of the design block as changed.

[0064] Specifically, the component characteristic type spectrum data sorted out and summarized by each specialty such as vehicle general layout, electrical system, power system, transmission system, steering system, braking system, suspension system, and body system are solidified as organizational knowledge in the system to effectively control the addition and modification by different designers. The component characteristic type spectrum data performs real-time comparison on the calculation results, performs background verification on the design results, and supports the traceability of module iteration and the implementation of modular management.

[0065] It is convenient to load the existing design data, support the overall call of the task plan of the developed vehicle models by technicians, and the partial borrowing of different vehicle model professional plans by different designers, maximizing the efficiency and flexibility of design and development.

[0066] In a preferred embodiment, the vehicle model management module is further configured to configure calculation formulas and their value ranges for parameter items with an associated relationship.

[0067] The design module is further configured to determine whether the values of all relevant parameter items are within the value range according to the calculation formula after the user fills in the parameter items. If not, an alarm message is output.

[0068] Specifically, a verification is formed by the results obtained by driving the calculation formula through the design parameters. By comparing the calculation results with the component type spectrum data in the database one by one, the system automatically determines whether the module is reused or newly added, thereby ensuring the implementation of modular management, and different results correspond to different approval processes.

[0069] By carefully sorting out all the calculation formulas required by various specialties such as vehicle general layout, electrical system, power system, transmission system, steering system, braking system, suspension system, and body system, all the calculation formulas of each specialty are embedded in the system bottom layer, enabling designers to get rid of the cumbersome and inefficient work of referring to calculation formulas based on EXCEL tables in the past, and thus focusing more on high-level design and development tasks such as the impact of the selection of variable parameters on product structure, function, performance, and modules.

[0070] In a preferred embodiment, the design template includes a two-dimensional analysis model and charts.

[0071] The design module is also used to automatically and real-time output the corresponding two-dimensional analysis model or chart after the user fills in the parameter items.

[0072] In this embodiment, according to the parameter values entered by the current designer, customized two-dimensional analysis models, charts, etc. are called in real time. Designers can intuitively understand the impact of each parameter change on the design scheme, and support the selection or review of the most suitable design scheme for the current development task.

[0073] In a preferred embodiment, the task assignment module is also used to store the designer information of all designers in all design departments. The designer information includes personnel on-duty information, personnel qualification information, work load information, and task completion accuracy information.

[0074] The task assignment module assigns the design tasks of the design blocks to the corresponding design departments according to the designer information, and assigns the parameter item design permissions of the corresponding design modules in the design template to the corresponding designers in the design departments.

[0075] Specifically, the capabilities and qualifications of design and development personnel in each department (such as technicians, supervisors, chief engineers, division managers, general engineers, etc.) are sorted out, and the information such as the affiliated professional department, current work load, and task completion on-time rate is summarized. Further, the vehicle model responsible person can, based on the above information, combined with the difficulty and urgency of the current vehicle model development task, etc., comprehensively judge the appropriate candidates to form a design and development team, effectively breaking through the department communication barriers and quantifying and revitalizing the R & D resources. For the entire technical center, visualize the work loads of various technical personnel, including the number of current development tasks, on-time rate, bottleneck resource allocation cycle, past task success rate, task difficulty, etc., to facilitate the vehicle model responsible person to allocate the best resources required for the current task.

[0076] In this embodiment, based on the vehicle model development scenario in the segmented market, the information source is unified, the team members of the development task are determined according to the specialty, and the mid-term change situation of the team members is recorded, effectively improving the symmetry of information within the design team and avoiding phenomena such as communication chaos and information loss.

[0077] The person in charge of the vehicle model can, according to the specialties actually involved in the current vehicle model tasks, direct the development tasks to the relevant professional members of the design team, effectively realizing the strong association between the vehicle model development tasks, developers, and calculation processes, and also improving the efficiency of collaborative development.

[0078] In a preferred embodiment, the design module is also used to record and save the design information of all designers in real time to form a visual progress chart.

[0079] Specifically, it efficiently summarizes the list of design and development tasks responsible for by current designers and the tasks decomposed by individuals, visually displays the processing progress, risks, and overdue situations of the design and development tasks currently responsible for by individuals, and synchronously pushes them through the client, email, and text messages to automatically remind the person in charge of the number of current development task problems, processing progress, whether it is overdue, etc. Through information technology means, the system automatically follows up the progress of development tasks, further integrating the interfaces of full-time and part-time personnel in each department.

[0080] Furthermore, for the summary of the development tasks responsible for by individuals, including the list of all vehicle model development tasks currently responsible for by individuals, through the task list link, designers can quickly understand the background, project difficulty level, customer category, design change points, configuration requirements, node requirements, etc. of the current development tasks, greatly shortening the information transfer link, reducing the time for one-way or multi-way communication through WeChat, QQ, email, etc., and improving the efficiency and accuracy of communication.

[0081] Dynamically display the processing progress of issues distributed to oneself by others and those transferred by oneself to other responsible persons. According to the set countermeasure cycle and nodes, the system evaluates risks in real time and notifies the superior manager of the responsible person of the overdue warning information through email, text message, etc., reminding the manager to intervene in a timely manner or provide support.

[0082] In this embodiment, the design and development process conditions of each designer participating in the current vehicle model task are recorded and saved in real time, visualizing information such as the development progress and design difficulties of the current vehicle model task, facilitating the process control, post-event traceability, and quick retrieval and call of the design scheme, and providing strong support for the one-time success rate of the design scheme.

[0083] In a preferred embodiment, the verification module is also used to configure different levels of verification processes according to the difficulty level of the vehicle model development tasks.

[0084] Specifically, according to the difficulty of vehicle model tasks, they are divided into levels A, B, and C, and according to the importance dimension of vehicle model tasks, they are divided into large customer order vehicle models, fleet user order vehicle models, general user order vehicle models, etc., loading the corresponding approval processes and approval node information, and real-time displaying the current approval progress.

[0085] Support the further decomposition of complex design tasks. Through the task transfer function, other relevant responsible persons can be decomposed to support cross-departmental collaboration to complete. For cross-departmental task transfers and transfers due to changes in designers within the department, the system records the transfer information and reasons for transfer, and the process is traceable, avoiding phenomena such as shirking responsibility.

[0086] For situations where it is difficult to define the interface responsible person and design difficulties, etc., through the escalation management function, it can be pushed to a higher-level management for summary and decision-making, avoiding the passive and inefficient waiting for difficult problems.

[0087] In summary, the present invention proposes a unified and efficient collaborative management method and system for vehicle projects from product definition, identification of design change points, design calculation, scheme verification, prevention of recurrence inspection, change management, product database update, module management, etc., for various departments and relevant specialties in vehicle model design and development.

[0088] Starting from the source of vehicle model development tasks, unify information sources such as parameter entry, standards and specifications, and design verification, as well as cross-departmental collaboration calibers. Orderly divide the vehicle model development tasks according to vehicle model series, forming the association between the input of each vehicle model design and development and the process data of design calculation and verification, and the efficient collaboration of each specialty. Support the vehicle model person in charge to enter the vehicle model development task book, support judging from the perspective of the whole vehicle and prominently marking the change points of the current development task relative to the basic vehicle model. By marking the change points, the development efficiency of adaptive development projects can be improved, so that project team members can efficiently focus on the design scheme of the change points and ensure the reuse of common modules.

[0089] By loading the embedded calculation formulas of each specialty, synchronously load the inspection modules, standards and specifications, prevention of recurrence data, and parametric models involved in the current vehicle model project from the background. In an integrated and visual way, unify the design and development processes of each specialty (here, all calculation formulas, parameters, and design standards involved in vehicle model calculation are integrated through information means), solve the problem of isolation of design parameters, data, etc., greatly simplify the difficulty of vehicle model design and development, and avoid problems such as missing items and manual entry efficiency.

[0090] By managing the calculation formula, defining the characteristics, types and transmission mechanism of common parameters, on the one hand, the communication methods of various professionals through WeChat, QQ, email, etc. are abandoned, the communication platform and caliber are unified, and the communication efficiency and accuracy are greatly improved. On the other hand, each common parameter participates in the automatic calculation of each system design scheme, which plays a role in boundary constraint and verification of the accuracy of the design scheme. (Based on the whole vehicle, define cross-professional common parameters. Different templates and common parameter libraries are defined for different market segments. Through the sharing of common parameters in various professions, boundary constraints and verification effects are achieved) After each professional scheme is confirmed or modified, a change version record is generated and broadcast to other related professions, maintaining the synchronization of change information (embedded change version rules, automatically forming change management). At the same time, according to the changes in parameter input, statistical analysis data and customized charts for each profession are generated in real time, supporting the rapid retrieval and flexible and diverse import and export of design and development process data, effectively supporting the optimization and review of design schemes, and reducing the statistical workload of full-time / part-time personnel in various professions.

[0091] The current vehicle model calculation process is classified and stored to form a professional parts model library, which supports the modular management and implementation of various professional models, and supports the efficient loading and reuse of subsequent development projects. (The vehicle model calculation process is based on the modular concept. Compared with the current model library, if the model library can retrieve the current module or model, the design plan is approved. If the model library cannot retrieve it, it is judged as a new module or a new model. Further, the system initiates approval through the embedded process. If the approval is passed, the new module or new model will be included in the current model library. Otherwise, the technician will be rejected and asked to resubmit the design plan).

[0092] The present invention proposes a collaborative calculation and verification management method and system for whole vehicle design based on informatization, innovates the design and development management method and management tool for commercial vehicles, and establishes a design and development management system of vehicle model project-parameter definition-module management-personnel management-approval decision-making-big data management. It connects many elements and links of the project from product definition, design change point identification, design calculation, scheme verification, anti-recurrence inspection, change management, product database update, module management, etc., effectively solves many problems such as data siloing, difficulty in modularization, chaotic design change version management, and disconnection between design calculation verification and project process, effectively improves the efficiency and accuracy of communication, and greatly reduces the interface between full-time / part-time personnel.

[0093] In view of the pain points, difficulties, and bottlenecks in the design and development field of commercial vehicle whole vehicle industry, the present invention first establishes a whole vehicle design collaborative calculation and verification management method and system. The system is based on the scenario-based requirements of whole vehicle project design collaborative calculation and verification, adopts a B / S architecture, uses a C#+.NetCore+Blazor+Alibaba Cloud technical solution, is deployed in the cloud, does not require the installation of a client, and has a seamless update. It supports design collaborative calculation and verification, version change, modular management, and supports email and SMS reminders to ensure the timeliness and completeness of information processing.

[0094] As Figure 2 shown, the present invention also provides a whole vehicle design collaborative calculation and verification management method, including:

[0095] Step S1: Configure design templates for different vehicle families. The design templates include multiple parameter items for components and their design prompt information. For parameter items with a sharing relationship, when the parameter item with design authority changes, other parameter items without design authority change synchronously. The design prompt information is used to provide design prompts for users when filling in parameter items. During the model iteration process of the same vehicle family, store the design templates for different vehicle models, and mark the parameter items that have changed in the latest vehicle model compared to the previous vehicle model in the design template.

[0096] Step S2: Retrieve the corresponding design template according to the vehicle type development task book, and assign the design authority of the parameter items to the corresponding designers.

[0097] Step S3: The designer retrieves the design template and fills it in. For the unchanged parameter items, retrieve the corresponding parameter values of the previous vehicle model for filling. For the changed parameter items, fill them in combination with the design prompt information.

[0098] Step S4: Configure a verification process for the unchanged parameter items and verify them.

[0099] In view of the pain points, difficulties, and bottlenecks in the design and development field of commercial vehicle whole vehicle industry, the present invention establishes a whole vehicle design collaborative calculation and verification management system and method, which can greatly improve the design and development efficiency and design quality, and support the creation of fast, accurate, and good capabilities under the background of large-scale customization of commercial vehicles. At the same time, it effectively reduces the workload of personnel (full-time / part-time) interface personnel by more than 80%, and supports modular management and design scheme optimization. Specifically:

[0100] 1. Optimize the Excel-based design calculation and development model of each system to improve development efficiency and accuracy. Support the implementation of standards and specifications, achieve 100% accuracy in design verification of new product development, and reduce ET issues of vehicle model projects by more than 60%.

[0101] 2. Strongly associated with the project, supporting version management, quickly focusing on change points, reducing personnel (full-time / part-time) interfaces by more than 80%, and improving communication efficiency between systems.

[0102] 3. Unified calculation platform and templates. Each profession can customize templates and support output of models, charts, etc. The calculation process and change history form a knowledge base for easy tracing and query.

[0103] 4. Establish professional parts databases and model databases, customize professional analysis and process management tools, and effectively support model management, modular management, and scenario-based solution optimization.

[0104] 5. Achieve efficient collaboration. Open up the communication channels and levels for cross-professional issues, break the barriers of cross-departmental collaborative work, and strengthen the work collaboration of various departments. By establishing a shared parameter and process data sharing mechanism, the use of communication tools such as email, WeChat, QQ, Feishu, and SMS is greatly reduced, effectively avoiding the phenomenon of multiple, multi-source, and scattered information input.

[0105] The present application is not limited to the above-mentioned implementation modes. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
