[0026] According to an embodiment of the present invention, a method for modeling a vehicle wiring harness is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0027] Figure 1 It is a flowchart of a method for modeling a vehicle wiring harness according to an embodiment of the present invention. The method may include the following steps:

[0028] Step S101, respectively determine the levels to which multiple wiring harnesses of the vehicle belong.

[0029] In the technical solution provided in step S101 of the present invention above, the above levels can be used to represent the assembly positions of multiple wiring harnesses of the vehicle. Among them, the assembly positions may include: the cab, the chassis, the engine, etc.

[0030] In this embodiment, the levels to which multiple wiring harnesses of the vehicle belong are respectively determined. Optionally, in this embodiment, multiple wiring harnesses of the vehicle are respectively divided, and the levels to which the multiple wiring harnesses belong can be obtained. Among them, the above division operation can be a top-down (TOP-DOWN) division operation.

[0031] Step S102: Determine the installation interfaces between different levels.

[0032] In the technical solution provided in step S102 of the present invention, the above installation interfaces can be used to represent the installation interfaces between multiple wire harnesses at different levels. For example, the above installation interfaces can be represented by a coordinate system, and the coordinate system can be divided into four coordinate systems: the vehicle coordinate system, the cab coordinate system, the engine coordinate system, and the rear axle coordinate system; the cab coordinate system can be defined based on the installation position of the cab on the vehicle, the engine coordinate system can be defined based on the installation position of the engine on the vehicle, and the rear axle coordinate system can be defined based on the installation position of the rear axle on the vehicle. This is only an example and is not specifically limited.

[0033] In this embodiment, after respectively determining the levels to which multiple wire harnesses of the vehicle belong, determine the installation interfaces between different levels. Optionally, based on determining the levels to which multiple wire harnesses of the vehicle belong, this embodiment can determine the installation interfaces between multiple wire harnesses at different levels.

[0034] Optionally, based on determining the levels to which multiple wire harnesses of the vehicle belong, the installation interfaces between multiple wire harnesses at the initial level and multiple wire harnesses at the next level can be determined. Among them, the initial level is higher than the next level, and the next level can be used to represent the sub-level obtained by dividing the initial level.

[0035] Step S103: Determine the respective initial wire harness constraint models corresponding to multiple current levels that meet the installation interfaces, where the initial wire harness constraint model is used to model the configuration states of multiple current wire harnesses at the current level.

[0036] In the technical solution provided in step S103 of the present invention, the above initial wire harness constraint model can be used to model the configuration states of multiple current wire harnesses at the current level, and the above initial wire harness constraint model can be a variant vehicle wire harness branch model, and the variant vehicle wire harness branch model can be constructed based on the basic vehicle wire harness model. That is to say, based on any vehicle model, a basic wire harness branch model is constructed, and based on the constructed basic vehicle wire harness model, a variant vehicle wire harness branch model can be constructed.

[0037] In this embodiment, after determining the installation interfaces between different levels, determine the respective initial wire harness constraint models corresponding to multiple current levels that meet the installation interfaces. Optionally, based on determining the installation interfaces, this embodiment can determine multiple current levels that meet the above installation interfaces, and then determine the respective initial wire harness constraint models corresponding to each of the multiple current levels.

[0038] Optionally, on the basis of determining the installation interface, if multiple current levels that meet the above installation interface are determined to be the above initial level and the above next level, then the initial wire harness constraint model corresponding to the above initial level and the initial wire harness constraint model corresponding to the above next level are further determined.

[0039] Optionally, the above basic wire harness branch model may include a main wire harness branch model and a functional branch wire harness model. Among them, the numbering format of the main wire harness branch model can be defined as cable - main - position - vehicle model number. For example, the number of the left main wire harness branch model of vehicle model A can be cable - main - left - A. The numbering of the functional branch wire harness model can be defined as cable - function implemented or assembly connected - position - vehicle model number. For example, the number of the left headlamp connection wire harness model of vehicle model A can be cable - headlamp - left - A.

[0040] Step S104: Combine multiple initial wire harness constraint models through the installation interface to obtain a target wire harness constraint model, where the target wire harness constraint model is used to model the configuration status of multiple current wire harnesses in the vehicle.

[0041] In the technical solution provided in step S104 of the present invention above, the above target wire harness constraint model can be used to model the configuration status of multiple current wire harnesses in the vehicle. For example, the above target wire harness constraint model can be a full - configuration wire harness assembly model or a partial - configuration wire harness assembly model.

[0042] In this embodiment, after determining the respective initial wire harness constraint models corresponding to multiple current levels that meet the installation interface, combine multiple initial wire harness constraint models through the installation interface to obtain a target wire harness constraint model. Optionally, on the basis of determining each initial wire harness constraint model, combine multiple initial wire harness constraint models through the determined above installation interface, and then configure the combined multiple initial wire harness constraint models to obtain a target wire harness constraint model.

[0043] Optionally, on the basis of determining each initial wire harness constraint model, combine multiple initial wire harness constraint models through the determined above installation interface. For example, through a predefined interface coordinate system, in a TOP - DOWN manner, layer by layer, combine the respective initial wire harness constraint models corresponding to each layer together, and thus multiple combined initial wire harness constraint models can be obtained.

[0044] Optionally, the combined multiple initial wire harness constraint models can be configured to obtain the target wire harness constraint model. That is, by performing parameter configuration on the combined multiple initial wire harness constraint models, the target wire harness constraint model can be obtained, where the above parameter configuration may include: attribute configuration, coordinate configuration, etc. This is only an example here and is not specifically limited.

[0045] It should be noted that the wire harness modeling method for vehicles in this application can be applied not only to specific types of vehicles (such as school buses and fire trucks, etc.), but also to other types of vehicles including but not limited to trucks, buses, sedans, etc. That is, as long as it involves the scenario of three-dimensional modeling of automotive wire harnesses, regardless of the type of vehicle, the wire harness of the vehicle can be modeled by the wire harness modeling method for vehicles in this application.

[0046] In steps S101 to S104 of the present application, when modeling the wire harness of a vehicle, the levels to which the multiple wire harnesses of the vehicle belong can be determined respectively. Then, the installation interfaces between different levels can be determined, and the respective initial wire harness constraint models corresponding to the multiple current levels that meet the above installation interfaces can also be determined. And through the above installation interfaces, the multiple initial wire harness constraint models are combined to obtain the target wire harness constraint model, thereby achieving the purpose of reducing the adjustment duration and adjustment workload of the model, thus solving the technical problem of low modeling efficiency of the wire harness of the vehicle, and further achieving the technical effect of improving the modeling efficiency of the wire harness of the vehicle.

[0047] The above method of this embodiment will be further introduced below.

[0048] As an optional embodiment, in step S101, determining the levels to which the multiple wire harnesses of the vehicle belong respectively includes: dividing the multiple wire harnesses according to the assembly information of the multiple wire harnesses in the vehicle to obtain levels, where the assembly information is used to represent the areas where the multiple wire harnesses are configured in the vehicle and the functions carried by the multiple wire harnesses in the vehicle.

[0049] In this embodiment, the above assembly information can be used to represent the areas where the multiple wire harnesses are configured in the vehicle and the functions carried by the multiple wire harnesses in the vehicle.

[0050] In this embodiment, according to the assembly information of multiple wire harnesses in the vehicle, the multiple wire harnesses are divided to obtain levels. Optionally, after obtaining the assembly information of the multiple wire harnesses in the vehicle, the multiple wire harnesses are divided according to the obtained assembly information, and the levels to which the multiple wire harnesses belong can be obtained. For example, according to the obtained assembly information, the multiple wire harnesses are divided from top to bottom, and the levels to which the multiple wire harnesses belong can be obtained, thereby achieving the purpose of grading the wire harnesses of the vehicle, and thus realizing the technical effect of improving the classification accuracy of the wire harnesses of the vehicle.

[0051] Next, the steps of determining the installation interfaces between different levels in this embodiment will be further introduced.

[0052] As an optional embodiment, different levels include: the first level, the second level, and the third level. The first level is higher than the second level, and the second level is higher than the third level. Step S102 of determining the installation interfaces between different levels includes: determining the first installation interface between the multiple wire harnesses at the first level and the multiple wire harnesses at the second level; and determining the second installation interface between the multiple wire harnesses at the second level and the multiple wire harnesses at the third level.

[0053] In this embodiment, the above different levels may include: the first level, the second level, and the third level. Among them, the first level may be higher than the second level, the second level may be higher than the third level. The second level may be used to represent the sub-level obtained by dividing the first level, and the third level may be used to represent the sub-level obtained by dividing the second level.

[0054] For example, the first level may include: the cab wire harness level, the chassis wire harness level, the engine wire harness level, etc. If the first level is the chassis wire harness level, the second level may be at least one or a combination of the following levels: the left side wire harness level, the right side wire harness level, the front wire harness level, and the rear wire harness level; if the second level is the front wire harness level, the third level may be at least one or a combination of the following levels: the front panel wire harness level, the air conditioner wire harness level, the fog lamp wire harness level, etc. This is only for example and not for specific limitation.

[0055] In this embodiment, after respectively determining the levels to which the multiple wire harnesses of the vehicle belong, the first installation interface between the multiple wire harnesses at the first level and the multiple wire harnesses at the second level can be determined, and the second installation interface between the multiple wire harnesses at the second level and the multiple wire harnesses at the third level can be determined, thereby achieving the purpose of determining the installation interfaces between the wire harnesses at different levels, and thus realizing the technical effect of improving the modeling accuracy of the wire harnesses of the vehicle.

[0056] For another example, if the first level is the chassis wiring harness level, the second level is the front wiring harness level, and the third level is the front panel wiring harness level, then based on determining the levels to which the multiple wiring harnesses of the vehicle belong, the first installation interface between the multiple wiring harnesses at the chassis wiring harness level and the multiple wiring harnesses at the front wiring harness level can be determined, and the second installation interface between the multiple wiring harnesses at the front wiring harness level and the multiple wiring harnesses at the front panel wiring harness level can be determined. This is only an example for illustration and is not specifically limited.

[0057] In this embodiment, the above different levels may include: the first level, the second level, the third level, and the fourth level. Among them, the first level may be higher than the second level, the second level may be higher than the third level, the third level may be equal to the fourth level, and the wiring harness corresponding to the third level is different from the wiring harness corresponding to the fourth level. The second level may be used to represent the sub-level obtained by dividing the first level, and the third level and the fourth level may be used to represent the sub-levels obtained by dividing the second level.

[0058] For example, the first level may include: the cab wiring harness level, the chassis wiring harness level, the engine wiring harness level, etc. If the first level is the chassis wiring harness level, the second level may be at least one of the following levels or a combination thereof: the left side wiring harness level, the right side wiring harness level, the front wiring harness level, and the rear wiring harness level; if the second level is the front wiring harness level, the third level may be the front panel wiring harness level, and the fourth level may be the air conditioning wiring harness level or the fog lamp wiring harness level, etc. This is only an example for illustration and is not specifically limited.

[0059] For another example, the first level may be represented by level 1, the second level may be represented by level 1.1, the third level may be represented by level 1.1.1, and the fourth level may be represented by level 1.1.2. This is only an example for illustration and is not specifically limited.

[0060] In this embodiment, after separately determining the levels to which the multiple wiring harnesses of the vehicle belong, the first installation interface between the multiple wiring harnesses at the first level and the multiple wiring harnesses at the second level can be determined, the second installation interface between the multiple wiring harnesses at the second level and the multiple wiring harnesses at the third level can be determined, and the third installation interface between the multiple wiring harnesses at the second level and the multiple wiring harnesses at the fourth level can be determined. Thus, the purpose of determining the installation interfaces between the wiring harnesses at different levels is achieved, and the technical effect of improving the modeling accuracy of the wiring harnesses of the vehicle is realized.

[0061] For another example, if the first level is the chassis wiring harness level, the second level is the front wiring harness level, the third level is the front panel wiring harness level, and the fourth level is the air conditioner wiring harness level, then based on determining the levels to which the multiple wiring harnesses of the vehicle belong, the first installation interface between the multiple wiring harnesses at the chassis wiring harness level and the multiple wiring harnesses at the front wiring harness level can be determined, and the second installation interface between the multiple wiring harnesses at the front wiring harness level and the multiple wiring harnesses at the front panel wiring harness level can be determined. Also, the third installation interface between the multiple wiring harnesses at the front wiring harness level and the multiple wiring harnesses at the air conditioner wiring harness level can be determined. This is only for illustrative purposes and is not specifically limited.

[0062] Next, the steps of combining multiple initial wiring harness constraint models through the installation interface to obtain the target wiring harness constraint model in this embodiment will be further introduced.

[0063] As an optional embodiment, step S104, combining multiple initial wiring harness constraint models through the installation interface to obtain the target wiring harness constraint model, includes: combining multiple initial wiring harness constraint models through the installation interface; configuring the combined multiple initial wiring harness constraint models using the vehicle's optional information to obtain the target wiring harness constraint model, where the optional information is used to represent the attributes of the multiple wiring harnesses configured in the vehicle and the coordinates of the terminals of the multiple wiring harnesses configured in the vehicle.

[0064] In this embodiment, the above optional information can be used to represent the attributes of the multiple wiring harnesses configured in the vehicle and the coordinates of the terminals of the multiple wiring harnesses configured in the vehicle. For example, the above optional information can be option selection parameters. The attributes of the multiple wiring harnesses configured in the vehicle can be described by the attribute parameters in the option selection parameters, and the coordinates of the terminals of the multiple wiring harnesses configured in the vehicle can be described by the coordinate parameters in the option selection parameters. The above terminals can also be referred to as wiring harness terminals and are used to specify the coordinates of the interface end.

[0065] In this embodiment, after determining the respective initial wiring harness constraint models corresponding to the multiple current levels that meet the installation interface, the multiple initial wiring harness constraint models are combined through the installation interface. Optionally, in this embodiment, based on determining the respective initial wiring harness constraint models, the multiple initial wiring harness constraint models are combined through the determined installation interface.

[0066] In this embodiment, after combining a plurality of initial wire harness constraint models through an installation interface, the combined plurality of initial wire harness constraint models are configured using the vehicle's optional information to obtain a target wire harness constraint model. Optionally, based on combining the plurality of initial wire harness constraint models, the combined plurality of initial wire harness constraint models are parameter-configured using the vehicle's optional information. For example, by performing attribute configuration and coordinate configuration on the combined plurality of initial wire harness constraint models, a target wire harness constraint model can be obtained, thereby achieving the purpose of modeling the vehicle's wire harness and realizing the technical effect of improving the modeling efficiency of the vehicle's wire harness.

[0067] The steps for constructing the database of this embodiment will be further introduced below.

[0068] As an optional embodiment, the method further includes: constructing a first database and a second database, where the first database includes candidate attributes of a plurality of wire harnesses, and the second database includes candidate coordinates of terminals of a plurality of wire harnesses.

[0069] In this embodiment, the above-mentioned first database may include candidate attributes of a plurality of wire harnesses. For example, the above-mentioned first database may also be referred to as a wire harness attribute library. This is only for illustrative purposes and not for specific limitation.

[0070] In this embodiment, the above-mentioned second database may include candidate coordinates of terminals of a plurality of wire harnesses. For example, the above-mentioned second database may also be referred to as a wire harness terminal library. This is only for illustrative purposes and not for specific limitation.

[0071] In this embodiment, a first database and a second database are constructed. Optionally, based on determining the type of data in the first database, the first database can be constructed. In addition, based on determining the type of data in the second database, the second database can be constructed, thereby achieving the purpose of constructing a database suitable for wire harness modeling and realizing the technical effect of improving the modeling efficiency of the vehicle's wire harness.

[0072] Optionally, based on determining the type of data in the first database, the first database can be constructed. For example, if it is determined that the type of data in the first database includes: cross-sectional form of the wire harness, size of the wire harness, color of the wire harness, and sheath type of the wire harness, etc., then the wire harness attribute library is constructed according to the above-mentioned type of data including the cross-sectional form of the wire harness, size of the wire harness, color of the wire harness, and sheath type of the wire harness.

[0073] Optionally, in the wire harness attribute library, the attributes of the wire harness branches are defined. Among them, the attributes of the wire harness branches may include: the cross-sectional form of the wire harness, the size of the wire harness, the color of the wire harness, and the sheath type of the wire harness, etc. Define the attribute number of the wire harness branch, and its format is cross-sectional form - cross-sectional size - sheath color - sheath material - bending radius. For example, for a wire harness branch with a circular cross-sectional form, a cross-sectional size of φ = 10 mm, a sheath color of red, a sheath material of corrugated pipe, and a bending radius of 10 mm, the attribute number is C-10-R-W-R10. This is only an example here and is not specifically limited.

[0074] Optionally, on the basis of determining the types of data in the second database, the second database can be constructed. For example, if it is determined that the types of data in the second database include: the name of the wire harness terminal model, the number of the wire harness terminal, and the coordinates of the specified interface end, etc., then construct a wire harness terminal library according to the above data types including the name of the wire harness terminal model, the number of the wire harness terminal, and the coordinates of the specified interface end.

[0075] Optionally, in the wire harness terminal library, the name of the wire harness terminal model, the number of the wire harness terminal model, and the coordinates of the specified interface end are defined. For example, define the number of the wire harness terminal model as C, the number of the terminal as 3D, and the number of the wire harness terminal 282080-1 model as C-282080-1-3D. This is only an example here and is not specifically limited. Among them, specify the coordinates of the interface end of the wire harness terminal, and the origin of the coordinates can be the wire outlet end point, the wire outlet direction can be the Z-axis, and the direction is positive.

[0076] Next, the steps of configuring the combined multiple initial wire harness constraint models using the vehicle's selection information to obtain the target wire harness constraint model in this embodiment will be further introduced.

[0077] As an optional embodiment, the method further includes: from the first database, determining the candidate attributes that meet the selection information as the current attributes of multiple wire harnesses, and from the second database, determining the candidate coordinates that meet the selection information as the current coordinates of the terminals of multiple wire harnesses; determining the current attributes as the attributes in the selection information, and determining the current coordinates as the coordinates in the selection information; using the vehicle's selection information to configure the combined multiple initial wire harness constraint models to obtain the target wire harness constraint model, including: configuring the combined multiple initial wire harness constraint models using the current attributes and current coordinates to obtain the target wire harness constraint model.

[0078] In this embodiment, from the first database, the candidate attributes that meet the matching information are determined as the current attributes of multiple wire harnesses, and from the second database, the candidate coordinates that meet the matching information are determined as the current coordinates of the terminals of multiple wire harnesses. Optionally, based on the construction of the first database and the second database, in the above first database, each candidate attribute is matched with the matching information. When a candidate attribute that meets the matching information is found, the candidate attribute that meets the matching information is determined as the current attributes of multiple wire harnesses; and, in the above second database, each candidate coordinate is matched with the matching information. When a candidate coordinate that meets the matching information is found, the candidate coordinate that meets the matching information is determined as the current coordinates of the terminals of multiple wire harnesses.

[0079] In this embodiment, the current attributes are determined as the attributes in the matching information, and the current coordinates are determined as the coordinates in the matching information. Optionally, based on the determination of the current attributes of multiple wire harnesses and the current coordinates of the terminals of multiple wire harnesses, the determined current attributes of multiple wire harnesses are determined as the attributes in the matching information, and the determined current coordinates of the terminals of multiple wire harnesses are determined as the coordinates in the matching information.

[0080] In this embodiment, the combined multiple initial wire harness constraint models are configured using the current attributes and the current coordinates to obtain a target wire harness constraint model. Optionally, based on the determination of the attributes and coordinates in the matching information, the attributes that are the current attributes of multiple wire harnesses and the coordinates that are the current coordinates of the terminals of multiple wire harnesses are used to perform parameter configuration on the combined multiple initial wire harness constraint models. For example, by performing attribute configuration and coordinate configuration on the combined multiple initial wire harness constraint models, a target wire harness constraint model can be obtained, thereby achieving the purpose of being able to model the wire harness of a vehicle, and thus realizing the technical effect of being able to improve the modeling efficiency of the wire harness of a vehicle.

[0081] In the embodiment of the present invention, when modeling the wire harness of a vehicle, the levels to which multiple wire harnesses of the vehicle belong can be determined separately. Then, the installation interfaces between different levels can be determined, and the respective initial wire harness constraint models corresponding to multiple current levels that meet the above installation interfaces can also be determined. By combining multiple initial wire harness constraint models through the above installation interfaces, a target wire harness constraint model can be obtained, thereby achieving the purpose of being able to reduce the adjustment duration and adjustment workload of the model, thus solving the technical problem of low modeling efficiency of the wire harness of a vehicle, and further realizing the technical effect of being able to improve the modeling efficiency of the wire harness of a vehicle.

[0082] The technical solutions of the embodiments of the present invention will be illustrated below in conjunction with preferred embodiments.

[0083] Due to the existing modeling method of the vehicle's wiring harness, the granularity of the wiring harness modeling is too large. Moreover, the wiring harness branches of the modeled wiring harness model are not independent model units, and there are correlation and dependency relationships between the wiring harness branches, which will cause the adjustment of the model to take a long time and the workload of the model adjustment to be large when the model is adjusted, resulting in the technical problem of low modeling efficiency of the vehicle's wiring harness.

[0084] To solve the above technical problems, the embodiment of the present invention proposes a modeling method for the vehicle's wiring harness. When modeling the vehicle's wiring harness, the levels to which multiple wiring harnesses of the vehicle belong can be determined respectively. Then, the installation interfaces between different levels can be determined, and the respective initial wiring harness constraint models corresponding to multiple current levels that meet the above installation interfaces can also be determined. By combining the multiple initial wiring harness constraint models through the above installation interfaces, a target wiring harness constraint model can be obtained, thereby achieving the purpose of reducing the adjustment duration and workload of the model, solving the technical problem of low modeling efficiency of the vehicle's wiring harness, and further realizing the technical effect of improving the modeling efficiency of the vehicle's wiring harness.

[0085] In this embodiment, by executing the modular wiring modeling method of the vehicle, the multiple initial wiring harness constraint models can be combined by using the installation interface to obtain the target wiring harness constraint model. For example, Figure 2 is a flowchart of a modular wiring modeling method for a vehicle according to an embodiment of the present invention. As Figure 2 shown, the method may include the following steps:

[0086] Step S201, perform a top-down hierarchical division of multiple wiring harnesses of the vehicle.

[0087] In the technical solution provided in step S201 of the present invention, the divided levels may include: the first level, the second level, and the third level. For example, the first level may be represented by level 1, the second level may be represented by level 1.1, the third level may be represented by level 1.1.1. Level 1 may include the chassis wiring harness level, level 1.1 may include the right longitudinal beam chassis wiring harness level, and level 1.1.1 may include the chassis power wiring harness level.

[0088] In this embodiment, perform a top-down hierarchical division of multiple wiring harnesses of the vehicle until the lowest-level wiring harness branches are divided.

[0089] Optionally, according to the assembly position of the wire harness, the above first level can be divided into a cab wire harness assembly, a chassis wire harness assembly, an engine wire harness assembly, etc.; at the second level, taking the chassis wire harness assembly as an example, mainly according to the position of the wire harness on the frame, it can be divided into a left wire harness module, a right wire harness module, a front wire harness module, and a rear wire harness module. Some wire harness modules can be divided into a brake wire harness module, a thermal management wire harness module, etc. according to functional configurations; at the third and fourth levels, it is further divided according to position or function. For example, at the third and fourth levels, taking the front wire harness module as an example, it can be further divided into a front panel wire harness module, an air conditioner wire harness module, a fog lamp wire harness module, etc.

[0090] After hierarchically dividing multiple wire harnesses of the vehicle from top to bottom, step S202 is entered to define the installation interfaces between different levels.

[0091] In the technical solution provided in step S202 of the present invention, the installation interfaces between multiple wire harnesses at different levels are defined. For example, the above installation interfaces can be represented by a coordinate system. This is only for illustrative purposes and is not specifically limited.

[0092] Optionally, the above coordinate system can be divided into four coordinate systems, that is, a vehicle coordinate system, a cab coordinate system, an engine coordinate system, and a rear axle coordinate system. The cab coordinate system, the engine coordinate system, and the rear axle coordinate system can be defined respectively based on the installation positions of the cab, the engine, and the rear axle on the vehicle.

[0093] After defining the installation interfaces between different levels, step S203 is entered to construct a wire harness attribute library.

[0094] In the technical solution provided in step S203 of the present invention, in the wire harness attribute library, the attributes of the wire harness branches are defined. Among them, the attributes of the wire harness branches can include: the cross-sectional form of the wire harness, the size of the wire harness, the color of the wire harness, the sheath type of the wire harness, etc.

[0095] Optionally, define the attribute number of the wire harness branch, and its format is cross-sectional form - cross-sectional size - sheath color - sheath material - bending radius. For example, the attribute number of a wire harness branch with a circular cross-sectional form, a cross-sectional size of φ = 10mm, a red sheath color, a corrugated pipe sheath material, and a bending radius of 10mm is C - 10 - R - W - R10.

[0096] After constructing the wire harness attribute library, step S204 is entered to construct a wire harness terminal library.

[0097] In the technical solution provided in step S204 of the present invention, in the wire harness terminal library, the name of the wire harness terminal model, the number of the wire harness terminal model, and the coordinates of the specified interface end are defined.

[0098] Optionally, define the name and number of the wire harness terminal model, and specify the coordinates of the interface end. For example, define the number of the wire harness terminal model as C, the number of the terminal as 3D, and the number of the wire harness terminal 282080-1 model as C-282080-1-3D. Among them, specify the coordinates of the interface end of the wire harness terminal. The origin of the coordinates can be the outgoing line end point, the outgoing line direction can be the Z axis, and the direction is positive.

[0099] After constructing the wire harness terminal library, enter step S205 to construct the wire harness branch library.

[0100] In the technical solution provided in step S205 of the present invention, in the wire harness branch library, the name of the wire harness branch model at each level, the number of the wire harness branch model at each level, and the installation interface are defined.

[0101] In this embodiment, based on any vehicle model, construct a basic wire harness branch model. Based on the constructed basic vehicle model wire harness model, a variant vehicle model wire harness branch model can be constructed.

[0102] Optionally, the basic wire harness branch model can include a main wire harness branch model and a functional branch wire harness model. Among them, the number format of the main wire harness branch model can be defined as cable-main-position-vehicle model number. For example, the number of the left main wire harness branch model of vehicle model A can be cable-main-left-A. The number of the functional branch wire harness model can be defined as cable-function realized or assembly connected-position-vehicle model number. For example, the number of the left headlamp connection wire harness model of vehicle model A can be cable-headlamp-left-A.

[0103] It should be noted that each basic wire harness branch model is an independent and assemblable model, and there is no reference and dependency relationship between the models. Among them, each basic wire harness branch model can be assembled using a coordinate system, and the coordinate system uses the interface coordinate system defined in step S202; the attributes of each basic wire harness branch model can be selected from the constraint attribute library constructed in step S203; for the wire harness branch that needs to use wire harness terminals, call the wire harness terminals from the wire harness terminal library constructed in step S204.

[0104] After constructing the wire harness branch library, enter step S206 to construct the wire harness assembly model.

[0105] In the technical solution provided in step S206 of the present invention, the respective initial wire harness constraint models corresponding to each level are assembled together through a predefined interface coordinate system, and using the configured optional parameters, configure the assembled respective initial wire harness constraint models, and a fully configured wire harness assembly model or a partially configured wire harness assembly model can be constructed.

[0106] Optionally, by assembling (or combining) the wire harness branch models created or called in step S205 layer by layer in a TOP-DOWN manner according to the hierarchy defined in step S201, a plurality of initial wire harness constraint models after combination can be obtained, that is, a wire harness assembly model after combination can be obtained; by performing parameter configuration on the wire harness assembly model after combination, a fully configured wire harness assembly model or a partially configured wire harness assembly model can be constructed.

[0107] It should also be noted that the method in this application can be applied not only to specific types of vehicles (such as school buses and fire trucks, etc.), but also to other types of vehicles including but not limited to trucks, buses, and sedans, etc. That is to say, as long as it involves the scenario of three-dimensional modeling of automotive wire harnesses, no matter what type of vehicle it is, the wire harness of the vehicle can be modeled through the modeling method in this application.

[0108] In this embodiment, after hierarchically dividing the multiple wire harnesses of the vehicle from top to bottom, the installation interfaces between different levels are defined, and then a wire harness attribute library is constructed, a wire harness terminal library is constructed, and a wire harness branch library is constructed. Finally, a wire harness assembly model is constructed, thereby achieving the purpose of reducing the adjustment duration and adjustment workload of the model, thus solving the technical problem of low modeling efficiency of the wire harness of the vehicle, and further achieving the technical effect of improving the modeling efficiency of the wire harness of the vehicle.
