Description

Technical Field

[0001] The present invention relates to the field of vehicle passive safety research and development, and in particular to an automated vehicle passive safety research and development platform, medium and equipment. Background Art

[0002] Passive safety development of a whole vehicle refers to setting specific development scoring targets in terms of vehicle body structure, pedestrian protection, occupant restraint system, child protection, etc. according to the requirements of established regulations and rules (such as C-NCAP), and finally meeting the corresponding assessment and evaluation requirements in the regulations through multiple rounds of Computer Aided Engineering (CAE) simulation analysis and collision test analysis. In the existing development technology, there is a lack of a unified full-cycle standardized passive safety project development platform. The project development management platform on the market cannot be applied to passive safety development and task management, so it is usually managed manually, which has the following disadvantages:

[0003] First, the standardization, process and automation of passive vehicle development are low. In repetitive work such as project management, personnel management, task execution and management, the efficiency is low and time-consuming; the development process lacks effective monitoring and analysis, and the ability to track and control problems and risks is poor, and they are not handled in a timely manner.

[0004] Second, during the development process, the vehicle model has complicated steps in data processing, analysis and optimization, calculation and transmission, submission and result acquisition, and uses many R&D tools with low automation, many repetitive tasks, long overall time consumption and low efficiency. Especially when submitting model data calculations, there is a lack of overall monitoring of the model's calculation server, and the calculation time cannot be estimated.

[0005] Third, the security and consistency of R&D data are poor, and it cannot be shared collaboratively. R&D data and R&D experience have not been accumulated and are difficult to reuse, which cannot effectively drive the development of new models, resulting in a waste of time and resources.

[0063] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] The purpose of the present invention is to provide an automated vehicle passive safety R&D platform, medium and equipment, which can improve the standardization, process and automation of vehicle passive safety development and achieve consistency of R&D data.

[0065] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0066] Example 1

[0067] like Figure 1 As shown, the present invention provides an automated whole vehicle passive safety R&D platform, medium and equipment, including: a role management module 01, a database management module 02, a development item design and management module 03 and a R&D tracking module 04; the role management module 01 is used to divide the platform users into roles and determine the role authority according to the role type; the database management module 02 is used to build a R&D data tree, manage the input data of the task, the process data in the task execution and the deliverable data of the task completion based on the role authority, and manage the information tag database corresponding to the minimum unit development item; the information tags in the information tag database include item attributes, deliverables, implementation types and regulations and procedures; wherein the item attributes are determined according to the regulations and procedures; the development item design and management module 03 is used to design and manage the development items according to the regulations and procedures based on the role authority, and select the information tags mapped to the minimum unit development items according to the information tag database; the development items include multi-level items; the R&D tracking module 04 is used to manage the whole vehicle passive safety R&D process and problem tracking and tracing, so as to realize closed-loop management of problems in R&D.

[0068] In actual applications, the role management module 01 divides the platform users into roles and uniformly manages all platform personnel.

[0069] There are 7 roles: leader, technical director, project manager, chief engineer, engineer, outsourced engineer, corresponding to 7 different permission levels: A, B, C, D, E, F and super. The permission level includes functional permission and data permission. When adding new personnel, the platform first identifies the user role, and then assigns the corresponding functional permission and data permission. The roles and corresponding permission levels are shown in Table 1.

[0070] Table 1

[0071]

[0072] Different roles are assigned different functional permissions and data permissions to strengthen the management and control of personnel and the division of permissions. Among them, the division of functional permissions realizes process standardization, clear tasks, clear rights and responsibilities, and unified evaluation, and the division of data permissions strengthens data security and confidentiality management.

[0073] In actual applications, the automated vehicle passive safety R&D platform identifies roles with functional permissions of the database management module 02 and performs database management operations.

[0074] The database management module 02 specifically includes: a research and development data management unit, an item attribute database management unit, an implementation type management unit, a deliverable management unit and a regulations and procedures management unit.

[0075] The R&D data management unit is used to construct an R&D data tree and manage the input data of the task, the process data during the task execution and the deliverable data after the task is completed based on the role authority.

[0076] Furthermore, the R&D data management unit generates an R&D data tree to uniformly manage the input data of the task, the process data during the task execution, and the deliverable data after the task is completed.

[0077] R&D data is managed using a tree structure. When a new project is created and a task is issued, the automated vehicle passive safety R&D platform automatically generates input data folders, process data folders, and deliverable folders for each task. Figure 2 shown.

[0078] The input data refers to the task data input into the automated vehicle passive safety R&D platform, and the process data refers to the data obtained during the task execution process, such as the process data generated by automated tools and automatic submission calculations during the simulation process.

[0079] The deliverable data is the deliverables obtained after the task is completed.

[0080] Unified data management enables collaborative sharing of R&D data. During the R&D process, data is automatically processed and archived to avoid problems such as scattered and inconsistent R&D data, difficulty in finding, difficulty in accumulating process data, and difficulty in archiving.

[0081] The entry attributes are used as information tags 1, and the entry attribute database management unit is used to add, modify and delete data values ​​of the entry attributes according to laws and regulations; the entry attributes include body structure, pedestrian protection, occupant restraint system, child protection and test verification.

[0082] Furthermore, managing entry attribute data values ​​includes: being able to add, modify, and delete entry attribute values.

[0083] For example: the main contents of passive safety development include body structure, pedestrian protection, occupant restraint system, child protection, test verification, etc., which are set as data values ​​of item attributes to form an item attribute database, including {structure, pedestrian protection, occupant restraint, child protection, test}.

[0084] The implementation type is used as information tag 2, and the implementation type management unit is used to design different processes and specific steps for each minimum unit development item and the task type under the minimum unit development item; wherein the processes are numbered in sequence to generate implementation type numbers, and the specific steps include structural crashworthiness data verification, pedestrian protection data verification, occupant restraint system data verification, structural crashworthiness simulation grid modeling, pedestrian protection simulation grid modeling, occupant restraint simulation grid modeling, structural crashworthiness analysis optimization, pedestrian protection analysis optimization, occupant restraint analysis optimization, structural crashworthiness model benchmarking, pedestrian protection model benchmarking, occupant restraint model benchmarking and vehicle testing.

[0085] Furthermore, each implementation type includes: implementation type number; standard name; specific steps.

[0086] Implementation types can be added, modified, and deleted, and the above three items of information can be managed and maintained, as shown in Table 2, which is a schematic table of implementation types.

[0087] Table 2

[0088]

[0089] Each specific step is divided into several modules, including mesh division, basic connection, model construction and working condition construction. Each module corresponds to a detailed workflow. For example, the corresponding modules and workflows for implementation type number 7 are as follows: Figure 3 shown.

[0090] The deliverable is used as an information tag 3, a deliverable management unit, to normalize and standardize the deliverable format of each of the minimum unit development items.

[0091] Furthermore, the deliverable format of each minimum unit development item is standardized and normalized to maintain the consistency and coordination of the deliverables and facilitate R&D data integration and archiving.

[0092] Table 3 is a schematic diagram of the form of standardized deliverables, as shown in Table 3.

[0093] Table 3

[0094]

[0095] The regulations and procedures are used as information tags 4, and the regulations and procedures management unit is used to add, edit and delete regulations and procedures.

[0096] By managing regulatory and procedural labels, the time and efficiency of adjusting passive safety development content are greatly saved.

[0097] For the same content in multiple regulations being developed at the same time, only different information tags need to be set 4; regulations will be updated at regular intervals, and when new regulations are released, only new labels of regulations and procedures need to be added and mapped to the development items, without the need to update the development content of the entire new regulation.

[0098] The present invention creates and manages an information tag database corresponding to the smallest unit development item, and uses item attributes, deliverables, implementation types, and laws and regulations as information tags for dynamic management, which is simple, efficient, and fast to update.

[0099] In practical applications, the development item design and management module 03 is used to design the contents of passive safety regulations and rules into standardized development item templates for unified management.

[0100] Based on the role management module 01, the automated vehicle passive safety R&D platform identifies the role with the functional authority of the database management module 02 to design and manage development items. The role with the functional authority of this module is the automated vehicle passive safety R&D platform administrator, and the authority level is F.

[0101] The database management module 02 selects information tags for mapping minimum unit development items.

[0102] The development item design and management module 03 specifically includes the following units.

[0103] The development item design unit is used to add, edit, merge, copy and delete development items according to business needs, and determine the mapping relationship between the minimum unit development item and the information tag.

[0104] Furthermore, each standardized item in the development item design unit includes basic information and label mapping.

[0105] Item management: The default minimum unit development item and all mapped information tags constitute the unique identification of an item. According to business needs, development items and information tags can be added, edited, merged, copied, and deleted. When managing development items, the automated vehicle passive safety R&D platform performs unique identification. If the uniqueness is met, the corresponding addition, editing, merging, copying, and deletion are performed.

[0106] Label mapping: select information label 1, information label 2, information label 3, and information label 4 for mapping the minimum unit development item, and select the data value from the information label database in the database management module 02, indicating that 4 is the information label table, as shown in Table 4.

[0107] Table 4

[0108]

[0109] By selecting data from each information tag database, a mapping of the minimum unit development entry to the four information tags was created.

[0110] After creating the mapping of the mapping information tag 1, all tasks under the minimum unit development item have a mapping relationship with the item attributes.

[0111] Information tag 2 is the implementation type. In the passive safety development item template, only the implementation type number needs to be selected. After creating the mapping of information tag 2, all tasks under the minimum unit development item have a mapping relationship with the implementation type.

[0112] After creating the mapping in the mapping information tag 3, all tasks and deliverables under the minimum unit development item have a mapping relationship.

[0113] Create a mapping of the mapping information label 4, and all tasks and regulations under the minimum unit development item have a mapping relationship.

[0114] The passive safety development content of the whole vehicle includes the body structure, pedestrian protection, occupant restraint system, child protection and other aspects of the regulations and rules. The regulations and rules for passive safety development will be updated at regular intervals. Each time the regulations and rules are updated, there will be slight changes or additions in the development content compared to the previous version of the regulations and rules.

[0115] All development contents are designed into standardized development items and label mappings. You only need to add or edit standardized development items and label mappings to meet different vehicle model development and multiple R&D goals. It is simple and efficient, with standardization and consistency.

[0116] The data association unit is used to associate all tasks under each minimum unit development item through item attributes and input data of the current task according to the R&D data tree.

[0117] Furthermore, the data association unit associates the development task with the input data. That is, during the execution of the current task, the automated vehicle passive safety R&D platform can accurately locate and quickly push the input data used in the current task.

[0118] After creating the mapping of mapping information tag 1, based on the R&D data tree in database management module 02, the automated vehicle passive safety R&D platform immediately creates a correspondence between item attribute values ​​and R&D data. All tasks under each minimum unit development item are associated and linked with the input data through the item attribute values. Figure 4 An example diagram of how to develop entries for entry attributes and minimum units and how to hook up input data is shown below. Figure 4 shown.

[0119] After obtaining input data through the R&D data tree in the database management module 02, the data obtained under this path are automatically labeled with the attribute value of the entry.

[0120] Through the mapping relationship between the minimum work item and item attribute, and the mapping relationship between input data and item attribute, the development task and input data are associated. That is, during the execution of the current task, the automated vehicle passive safety R&D platform can accurately locate and quickly push the input data used for the current task. There is no need to manually search for the input data of the task one by one from all the large-scale input data in the project R&D data as in the past, which greatly saves the time of task execution.

[0121] For example, there are two work items and corresponding default tasks, and the task data are structure data and line security data respectively. Table 5 is a task data push table, as shown in Table 5.

[0122] Table 5

[0123]

[0124] The deliverable association unit is used to associate all task deliverable data under each minimum unit development item according to the R&D data tree, and create a deliverable data path for each minimum unit development item.

[0125] Furthermore, the deliverable association unit uniformly manages and automatically archives the deliverable data.

[0126] After creating the mapping of the mapping information tag 3, the format of the deliverables of each minimum unit development item is normalized and standardized. Next, based on the R&D data tree in the database management module 02, the automated vehicle passive safety R&D platform immediately creates a deliverable data path for all tasks under each minimum unit work item, which is used to obtain the deliverable data after the task is completed. This avoids the problems of difficult search, inability to collaborate, and inconvenience in archiving when manually managing deliverables.

[0127] The implementation visualization unit is used to select the implementation type number, develop the implementation type mapped according to the minimum unit to which the current task belongs, and visualize the specific steps included in the implementation type.

[0128] Furthermore, during the task implementation process, the specific steps included in the implementation type are displayed visually.

[0129] Information tag 2 is the implementation type. In the passive safety development item template, you only need to select the implementation type number. After creating the mapping of information tag 2, the automated vehicle passive safety R&D platform will visualize the specific steps included in the implementation type based on the information tag 2 mapped by the minimum unit development item to which the task belongs.

[0130] According to the automated vehicle passive safety R&D platform, the smallest unit development items associated with the task are matched, and according to the information tag 2: implementation type mapped by the smallest unit, each module and workflow in the specific steps of the task is visualized. This realizes the standardization and process of task execution, facilitates problem tracing, and greatly improves the quality and efficiency of task completion.

[0131] In practical applications, the R&D tracking module 04 is used to manage the closed-loop problems in the entire process of vehicle passive safety R&D.

[0132] The R&D tracking module 04 specifically includes: a problem tracking template management unit, which is used to add, edit and delete problem tracking templates; and a problem processing unit, which is used to track and trace and manage the vehicle passive safety R&D process.

[0133] Furthermore, the R&D tracking module 04 tracks and traces the source and manages the problems of the entire passive safety R&D process. Based on the role management module 01, the automated vehicle passive safety R&D platform identifies the role with the functional authority of the R&D tracking module 04, selects the problem tracking template, reports the problem according to the template, and associates it with the task in the task execution unit, and conducts closed-loop management of problem review, plan adjustment, risk conversion, and solution closure. The drawbacks of manual management of problems are reduced, and projects and R&D processes are managed more reasonably.

[0134] In practical applications, the present invention further includes: an automatic submission calculation module 05; the automatic submission calculation module specifically includes: a server management unit for managing servers; the server management unit includes adding servers, deleting servers, and editing and modifying server settings;

[0135] A server monitoring unit is used to send a request command to the server according to the set time and frequency to obtain monitoring data of all started servers; the monitoring data includes server IP, total number of cores, remaining number of cores, number of queued tasks and default number of cores; a model submission unit is used to create a computing job according to the model data in the R&D data tree, upload the computing job based on all started servers, and, after submitting the computing job, use the ID information data returned by the server as a unique identifier, and during the computing process, return the animation or curve result file of the completed calculation and the process record file containing the calculation information in real time, and obtain the results returned by the server after the calculation is completed and automatically filter the valid result files; the returned results include animation result files, curve result files, process record files containing calculation information, calculation log files and configuration files; the configuration file is other configuration files, and the returned valid results are defined as: animation, curve and process record file containing calculation information.

[0136] Automatic Submission Calculation Module 05 Based on R&D data, the model can automatically submit calculations, process monitoring and result downloads. The processing flow is as follows Figure 6 shown.

[0137] Furthermore, the server monitoring unit transmits the model data to the server monitoring unit based on the server management unit. According to the set time and frequency, a request command is sent to the server to obtain the monitoring data of all started servers; the monitoring data includes the server IP, the total number of cores, the number of remaining cores, the number of queued tasks, and the default number of cores.

[0138] The model submission unit includes: job submission and process monitoring.

[0139] Among them, submitting a job: for the model data in the R&D data tree, create a calculation job, based on the server management unit, obtain a list of all started servers, set three job submission methods, and submit it to the server for calculation according to the situation.

[0140] Manual submission: Based on the computing server monitoring unit, manually select the required server, enter the required number of cores, and submit the job calculation.

[0141] Automatic submission: No need to manually select the server and number of cores. The system will perform a traversal search based on the default number of cores and submit the calculation to the server that meets the conditions.

[0142] Calculation: To save computing resources, you can use a smaller number of cores to calculate the model.
