Description

Technical Field

[0001] The present invention relates to the technical field of vehicle wiring harness design, and in particular to a configuration design method and system for a whole vehicle wiring harness. Background Art

[0002] As the demand for customization in the automotive market continues to increase, the diversity of vehicle configurations has increased significantly, and there are obvious differences in the functional configurations, control systems, and wiring requirements of different models. Traditional wiring harness design methods usually rely on manual CAD drawings, and independently generate wiring harness drawings for each order requirement. Although this method can meet personalized configurations, the lack of a unified design benchmark not only leads to low design efficiency, but also the inability to reuse designs between models, increasing duplication of work and reducing design efficiency. At the same time, since the drawings and design logic are independent of each other, it is difficult to quickly adjust the design results when the configuration changes, which can easily lead to design errors. In addition, the wiring harness path information in the prior art is usually weakly correlated with the vehicle's functional configuration. When the functional requirements change, the wiring layout needs to be completely redesigned, further reducing the design efficiency.

[0027] Combine the following Figure 1-Figure 7 The invention describes a vehicle wiring harness configuration design method, system, electronic device and storage medium.

[0028] Figure 1 This is one of the flow charts of the vehicle wiring harness configuration design method provided by the present invention, such as Figure 1 As shown, including but not limited to the following steps: Step 101: According to the basic information of the vehicle, the root model of the vehicle is matched from a preset root model database.

[0029] In step 101, the root model of the vehicle is matched from the preset root model database according to the basic information of the vehicle. This step is designed to provide accurate initial conditions for the subsequent wiring harness design process and provide basic data support for automated design by establishing the association between the model and the configuration.

[0030] In actual implementation, the basic information of a vehicle usually includes key parameters such as platform, brand, sub-line, chassis type, electrical architecture, drive mode, emission standards, etc. Through these parameters, the characteristics of the vehicle can be compared one by one with the root models in the preset root model database to screen out the target root models that meet the conditions. The root model database pre-stores the model data of different platforms, including wiring harness master diagrams, functional characteristics, configuration characteristics and other information to ensure that the matching root model can fully cover the actual needs of the target vehicle.

[0031] During the specific execution, the system first extracts the basic information of the vehicle from the sales configuration ordering system, and then gradually screens according to the hierarchical relationship based on the division architecture of the root model database. From the platform level to the brand sub-line level, and then to the chassis type, electrical architecture, drive mode, emission standards, etc., the system gradually compares and finally locates the only target root model. During the comparison process, if certain parameters match multiple root models, the system will further sort them according to sales priority or configuration feature matching, and select the best root model. If the basic information of the vehicle cannot completely match the existing root model, the system will generate a prompt message, suggesting that the designer update the root model database to ensure the integrity and dynamic adaptability of the database.

[0032] Step 102: Determine the wiring harness master diagram and basic wiring harness path information corresponding to the root vehicle model.

[0033] In step 102, it is necessary to determine the wiring harness master diagram and basic wiring harness path information corresponding to the root vehicle model. The design purpose of this step is to quickly extract the basic wiring harness design information matching the target vehicle based on the core data of the root vehicle model, including the overall wiring harness master diagram and basic path layout, to provide a direct input source for subsequent configuration design and sub-diagram generation. Doing so can not only ensure the standardization and consistency of the design process, but also avoid inefficiency and errors caused by repeated definition of path information or master diagrams.

[0034] In one possible implementation, the wiring harness master diagram includes at least one preset configuration feature, each preset configuration feature corresponds to a candidate feature data set; the basic wiring harness path information includes a main path, and the main path is provided with at least one preset branch point and at least one optional branch point, and each optional branch point corresponds to a preset configuration feature.

[0035] Specifically, first, according to the target root vehicle model matched in step 101, the corresponding wiring harness master diagram in the preset root vehicle model database is searched. The wiring harness master diagram is designed according to the 150% function coverage principle and contains all the configuration features and path planning information that the target vehicle model may need. Multiple configuration features are preset in the master diagram, and each configuration feature corresponds to a candidate feature data set, which is used to define the possible function implementation methods under different vehicle configurations. At the same time, the master diagram contains a main path, referring to Figure 2 , Figure 2 This is a basic wiring harness path diagram provided by the present invention. The main path covers the basic layout of the key wiring harness of the whole vehicle, and defines preset branch points and optional branch points at key nodes. The preset branch points are fixed universal nodes, while the optional branch points are used to adapt to specific configuration requirements. Each optional branch point is associated with a preset configuration feature. Figure 2 As shown in the figure, preset branch points such as A1, A3 and A4 represent fixed functional nodes. Their positions in the main path are defined by the parent diagram and cannot be changed with changes in configuration or vehicle parameters. These branch points realize basic electrical connection functions by connecting with related equipment (such as cab flip switch, electric lift pump, left marker light, etc.). Optional branch points such as A2 and A5 are flexible nodes designed to adapt to specific vehicle configuration requirements. Whether these branch points are enabled or not depends on the actual configuration characteristics. For example, when the configuration requirements of the target vehicle include special requirements for the left rear taillight, the optional branch point A5 will be activated and the relevant equipment will be connected.

[0036] It should also be noted that in addition to the definition of branch points, the spacing between branch points in the main path is also a key factor in achieving configuration flexibility. Fixed preset spacing (such as a1, a2, a3, a4) is used to define the standard distance between preset branch points. These spacings cannot be adjusted to ensure the consistency of standardized production and assembly. Optional spacing (such as x1 and x2) can be dynamically adjusted according to actual needs. For example, the length of x1 and x2 can be configured based on the wheelbase or chassis length of the vehicle to meet the layout requirements of different models.

[0037] When extracting the basic path information of the wiring harness, the system will identify the key node positions and branch point types on the main path according to the attributes of the target root vehicle model and the corresponding functional requirements. For each branch point, the system will further retrieve the preset configuration features associated with it and verify whether the candidate feature data set covers the specific needs of the target vehicle. If some preset configuration features fail to find a match in the candidate data set, the system will record these features and generate prompt information to provide a basis for the subsequent update of the configuration feature data or the parent diagram expansion design.

[0038] Step 103: Obtain vehicle configuration information.

[0039] Specifically, the system first extracts the configuration information associated with the vehicle order from the sales order system, which includes the functional requirements, assembly location, length requirements and other optional configuration features of the vehicle. The extracted configuration information is encoded in the form of a string, where each configuration point corresponds to an actual configuration feature, which structurally matches the preset configuration features in. Subsequently, the system decodes these configuration strings and compares the extracted actual configuration features one by one with the candidate feature data set corresponding to each preset configuration feature in to confirm whether there is a completely matching candidate feature data.

[0040] Step 104: Generate a wiring harness sub-diagram according to the configuration information and the wiring harness parent diagram.

[0041] In step 104, a wiring harness sub-graph is generated based on the configuration information and the wiring harness parent graph. The core purpose of this step is to simplify the full-function coverage content in the parent graph into a wiring harness sub-graph that meets the actual needs of the target vehicle through a configurable design method, thereby achieving customization and efficiency of the wiring harness design and ensuring the logical correlation between the sub-graph and the parent graph. This can reduce redundant design, improve resource reuse, and meet the rapid response to different vehicle configuration requirements.

[0042] In one possible implementation, refer to Figure 3 , Figure 3 This is the second flow chart of the vehicle wiring harness configuration design method provided by the present invention, such as Figure 3 As shown, step 104 specifically includes steps 201-202: Step 201: According to configuration information, select first actual feature data from a set of candidate feature data corresponding to each preset configuration feature.

[0043] In step 201, the first actual feature data is selected from the candidate feature data set corresponding to each preset configuration feature according to the configuration information. The purpose of this step is to screen out the first actual feature data that matches the actual vehicle configuration information and the preset configuration features in the parent diagram, provide accurate feature input for the subsequent wiring harness sub-diagram generation, ensure that the design result meets the actual configuration requirements of the vehicle, and retain the logical consistency of the parent diagram and the sub-diagram.

[0044] In one possible implementation, refer to Figure 4 , Figure 4 This is the third flow chart of the vehicle wiring harness configuration design method provided by the present invention, such as Figure 4 As shown, step 201 specifically includes steps 301-302: Step 301: extract at least one actual configuration feature and second actual feature data corresponding to each actual configuration feature from configuration information.

[0045] In specific implementation, the system first receives the configuration information transmitted from the sales order system. This information is usually stored in the form of configuration strings or specific codes, describing the functional configuration and optional requirements of the vehicle. The system decodes this information into multiple actual configuration features through the configuration parsing module. For example, an actual configuration feature may be "solenoid valve", which is one of the key configuration features preset in the parent map, indicating that the target vehicle requires a solenoid valve device at a specific location.

[0046] Next, the system will extract the specific value of each actual configuration feature, that is, the second actual feature data. Taking the actual configuration feature "solenoid valve" as an example, the second actual feature data may be a specific manufacturer or model, such as "solenoid valve of manufacturer A" or "solenoid valve of manufacturer B". Taking the actual configuration feature "number of speakers" as an example, the second actual feature data can be "single speaker" or "double speakers". This specific value comes from the requirements clearly stated in the configuration information, or is derived by matching with the candidate feature data set.

[0047] Step 302: When it is determined that all actual configuration features match all preset configuration features, if each second actual feature data can find a corresponding match in the candidate feature data set corresponding to the preset configuration feature, each second actual feature data is determined as the first actual feature data corresponding to the preset configuration feature.

[0048] In specific implementation, the system first compares each actual configuration feature extracted in step 301 and its corresponding second actual feature data one by one. The core logic of the comparison is to verify whether each second actual feature data can find a corresponding match in the candidate feature data set of the preset configuration feature. The candidate feature data set is the possible value range defined for each preset configuration feature in the parent graph. For example, for the actual configuration feature "solenoid valve", the candidate feature data set may include "solenoid valve of manufacturer A" and "solenoid valve of manufacturer B". If the second actual feature data of the target vehicle is "solenoid valve of manufacturer A", the system will find a complete match in the candidate feature data set and mark it as matched.

[0049] When all the second actual feature data are matched successfully, the system will take these data as valid first actual feature data and store them in the data table. At the same time, the system will dynamically update the configuration status and mark the successfully matched features as processed to ensure that these features can be correctly referenced in subsequent steps.

[0050] In a possible implementation, after step 302, the method further includes the following steps: When it is determined that all actual configuration features match all preset configuration features, if third actual feature data exists, the third actual feature data is recorded; the third actual feature data is the second actual feature data for which no corresponding matching item can be found in the candidate feature data set corresponding to the preset configuration feature; updating the candidate feature data set of each preset configuration feature according to all third actual feature data; When it is determined that there is at least one actual configuration feature that fails to match any preset configuration feature, all preset configuration features are updated according to all unmatched actual configuration features.

[0051] Specifically, after completing the matching verification of step 302, the system performs a secondary analysis on all actual configuration features to find out whether there is any feature data that is not covered by the candidate feature data set. These unmatched features are defined as the third actual feature data. Taking the actual configuration feature "solenoid valve" as an example, if the target vehicle needs to use the "solenoid valve of manufacturer C", but the corresponding candidate feature data set in the parent graph only contains "solenoid valve of manufacturer A" and "solenoid valve of manufacturer B", then "solenoid valve of manufacturer C" is identified as the third actual feature data.

[0052] Once the system identifies the third actual feature data, it will record it in detail, including the name of its actual configuration feature (such as "solenoid valve"), the specific feature value (such as "solenoid valve of manufacturer C"), and its contextual information in the configuration (such as vehicle wheelbase, functional module, etc.). The system will store this data in the unmatched feature data table and generate update prompts related to the parent diagram. For example, the prompt information may include "Add solenoid valve of manufacturer C to the candidate feature data set" or "Expand the range of options for solenoid valves in the parent diagram."

[0053] At the same time, the system will analyze whether the unmatched features belong to common feature requirements. If it is judged to have broad adaptability (such as a feature that appears multiple times in a specific vehicle series), the system will also recommend that designers prioritize it in the parent graph update plan. For individual exceptions, the system will temporarily reference these third-party actual feature data when generating sub-graphs to ensure design integrity and mark the relevant paths and nodes in the sub-graphs for subsequent corrections.

[0054] Subsequently, the system generates an expansion plan based on the update requirements and dynamically adjusts the candidate feature data set. For example, for the candidate feature data set of "solenoid valve", the system will add "solenoid valve of manufacturer C" to the set and update all associated paths and node information related to it. In addition, the system will add corresponding comments or marks to the parent graph to indicate that these newly added data have been included in the parent graph expansion range for subsequent verification by designers.

[0055] After completing the update of the candidate feature data set, the system will also verify the expanded set to ensure the rationality and adaptability of the newly added feature data. For example, the system will verify whether the newly added feature data conforms to the design logic of the parent diagram and the actual requirements of the vehicle configuration, and generate an automated test report. If potential conflicts are found (such as path lengths exceeding a reasonable range or functional conflicts), the system will mark the conflict point and prompt the designer to intervene manually.

[0056] Furthermore, if the system identifies all actual configuration features that fail to match the preset configuration features, the system will classify and sort out these unmatched features, including feature name, function category, associated context information (such as vehicle wheelbase, equipment layout location), and source information (such as specific order number). For example, if the actual configuration feature "on-board camera" fails to match the preset configuration feature of the parent image, the system will record its specific parameters, such as "on-board camera with a resolution of 1080p".

[0057] Next, the system dynamically adjusts the preset configuration features in the parent graph based on the results of the classification. The core logic of the adjustment is to integrate the unmatched actual configuration features into the configuration feature structure tree of the parent graph to ensure that the new configuration requirements can be fully covered by the parent graph. For example, for the newly added "car camera", the system will add the corresponding preset configuration feature node in the functional configuration branch of the parent graph, and associate it with its possible candidate feature data sets (such as "720p camera", "1080p camera", etc.). This expansion operation ensures that the parent graph can support similar configurations that may appear in the future.

[0058] After completing the expansion of the parent diagram, the system will further synchronize and update all related harness paths and node information. Taking the "vehicle camera" as an example, the system will define its standard layout position in the parent diagram and preset the required harness branch points and path planning for it. At the same time, the system will automatically associate the adapted path parameters, such as harness length or connector type, to form a complete configuration feature definition.

[0059] In addition, the system will perform logic verification and consistency checks on the updated parent diagram to ensure that the extended preset configuration features will not cause conflicts or redundancy. For example, if the newly added configuration features may overlap with existing features, the system will prompt the designer to optimize the feature definition or readjust the structure of the feature tree. For the newly added feature data, the system will also recommend simulation verification or small-batch trial production to verify its adaptability and practicality.

[0060] Step 202: Generate a wiring harness sub-graph according to the first actual feature data corresponding to each preset configuration feature.

[0061] In step 202, a wiring harness sub-map is generated according to the first actual feature data corresponding to each preset configuration feature. The purpose of this process is to dynamically adjust the common design part in the parent map by combining the preset configuration features in the parent map with the actual configuration requirements of the vehicle, thereby generating a wiring harness sub-map that is fully adapted to the functional requirements and layout requirements of the target vehicle.

[0062] In specific implementation, the system first analyzes the corresponding preset configuration features based on the first actual feature data. These preset configuration features are standard functional modules defined in the parent diagram, covering main path information, branch nodes, device attachment points, and candidate feature data sets. The actual configuration features are the specific implementation of these preset configuration features, such as determining whether a branch point is enabled and the specific parameters of its attached device.

[0063] Next, the system screens and adjusts the common parts in the parent diagram. For fixed preset configuration features, the sub-diagram directly inherits the default values ​​of the parent diagram; for dynamically adjusted optional configuration features, the system updates its parameter values ​​according to the needs of the actual configuration features. In this process, the system will generate detailed sub-diagram information, including the branch structure of the main path, the connection relationship of the branch point, the device type, the connection interface and related parameters (such as cable length, shielding type, etc.). All adjusted data will be automatically written to the harness sub-diagram file.

[0064] Step 105: Update the basic wiring harness path information according to the wiring harness sub-graph to generate actual wiring harness path information.

[0065] In step 105, the basic wiring harness path information is updated according to the wiring harness sub-map to generate actual wiring harness path information. The core purpose of this step is to combine the preset basic path planning in the parent map and the dynamically adjusted configuration features in the sub-map to accurately revise the wiring harness path information, thereby generating actual wiring harness path information that fully adapts to the needs of the target vehicle.

[0066] In one possible implementation, refer to Figure 5 , Figure 5 This is a fourth flow chart of the vehicle wiring harness configuration design method provided by the present invention, such as Figure 5 As shown, step 105 specifically includes steps 401-402: Step 401: Determine a mapping relationship between each first actual feature data and each optional branch point.

[0067] Step 402: According to the mapping relationship, the basic wiring harness path information is updated to generate actual wiring harness path information.

[0068] In specific implementation, the system first parses the dynamic configuration content involved in the first actual feature data, including configuration function, layout location and device type. These data directly affect the enabling status and path design of the optional branch point. For example, for the actual configuration feature "on-board camera" of the target vehicle, the first actual feature data may point to "enable the on-board camera function and place the device on top of the rearview mirror". Based on this configuration requirement, the system determines that it needs to be connected to the optional branch point A2 on the main path.

[0069] Next, the system retrieves a list of optional branch points in the parent map, such as A2 and A5, and analyzes their preset functional ranges and attachment relationships. The system compares the dynamic requirements in the first actual feature data with the functional descriptions of the optional branch points in the parent map, for example, confirming whether branch point A2 supports the attachment function of the "vehicle camera" and verifying whether the layout position of the branch point is consistent with the position specified in the first actual feature data. If the branch point function and layout match, the system records the mapping relationship and marks branch point A2 as enabled. At the same time, the system extracts the path information of branch point A2, such as the default path length and branch node type, for subsequent adjustments.

[0070] If some of the first actual feature data cannot be mapped to any optional branch point, the system will record these unmatched features and generate a prompt message, asking the designer to check whether the optional branch point definition of the parent diagram needs to be expanded or adjusted. For example, if the target vehicle has a new configuration requirement of "auxiliary camera", but the corresponding branch point is not defined in the parent diagram, the system will prompt that a new branch point needs to be added and associated with the actual configuration feature.

[0071] After the mapping relationship is determined, the system will generate a complete mapping table, listing all the first actual feature data and the associated information of the optional branch points, including the branch point number, function description, layout location and the type of equipment it is attached to. These mapping data will serve as the direct basis for path update and actual harness path information generation in subsequent steps.

[0072] Furthermore, the basic harness path information is updated according to the mapping relationship. After the update is completed, the system performs consistency verification on the entire path information, including whether the path length meets the specifications, whether the branch point activation status is consistent with the mapping table, and whether the logical relationship of the attached equipment is complete. If the verification passes, the system generates the actual harness path information and stores it as a structured data file, and outputs the relevant design documents and technical drawings. These output files contain complete path planning, node annotations and parameter descriptions, which can be directly used in the production and assembly of harnesses.

[0073] Step 106: Generate a wiring harness configuration drawing of the vehicle according to the actual wiring harness path information.

[0074] In step 106, the wiring harness configuration drawings of the vehicle are generated based on the actual wiring harness path information. The purpose of this step is to concretize the actual wiring harness path information after dynamic adjustment in the form of drawings to form a complete design output. These drawings are not only the direct basis for production and manufacturing, but also an important reference for subsequent assembly, quality inspection and maintenance. This can ensure the operability and traceability of the design results, while improving the efficiency and standardization of the design process.

[0075] In specific implementation, the system first calls the actual harness path information generated in step 402, which includes the main path planning, branch point activation status, path length parameters, device connection relationship and related node attributes (such as interface type, cable specifications). The system builds a logical model of the harness configuration based on this data and converts it into basic data for drawing generation.

[0076] During the drawing generation process, the system visualizes the path and node information. For example, the main path is represented by a straight line, each branch point (such as A1, A2, A5) is marked with a node, and the enabled branch points are distinguished by different colors or line types to clearly show their actual status. For dynamically adjusted path parts (such as x1 and x2), the system will clearly mark their actual length values ​​and adjustment basis in the drawings, such as "x1=450mm, adjustment basis: target vehicle wheelbase". At the same time, the system marks the functional description of the branch point and the type of attached equipment in the drawing, such as "branch point A2: Attach 1080p vehicle-mounted camera, interface type: round multi-pin plug".

[0077] While generating the complete path structure, the system will also automatically generate the harness specification table and node attribute table based on the actual harness path information. These tables are attached to the drawings in the form of appendices, detailing the cable model, cross-sectional area, shielding type, length of each path, as well as the equipment mounting information, interface type and location description of each branch point. For example, "Path P1: Cable model Y123, cross-sectional area 2.5mm², shielding type: unshielded, length 450mm".

[0078] Before the drawing is output, the system will perform a consistency check on the generated results to check whether the drawing fully reflects all elements of the actual harness path information. For example, check whether the connection between the main path and the branch point is correct, whether the dynamically adjusted path parameters are consistent, and whether the node description of the attached device is complete. If the check passes, the system generates the final harness configuration drawing and outputs it in a standardized format (such as PDF, DWG) for production and technical archiving.

[0079] Through this process, step 106 realizes efficient conversion from actual harness path information to harness configuration drawings. This conversion ensures that the design results are highly operational, while providing clear and detailed technical documents, providing a reliable basis for production, assembly and maintenance. In addition, the generated drawings are consistent with the actual harness path information, providing a convenient traceability path for subsequent design changes or configuration adjustments.
