[0019] In a specific embodiment of the present invention, it is applied to any vehicle.

The bill of materials database can store the vehicle parts bill of materials and can also include model assembly related information.

The automatic assembly function module can call the model according to the model assembly data table, and start the automatic assembly process to generate a complete vehicle model; the inspection rule database includes a preset matching parts list, and the matching parts list can be optimized according to the complete vehicle model, and the part in the complete vehicle model that has been modified or updated is determined to obtain the target matching parts list of the part, and then the target matching parts list is sent to the automatic inspection function module, and the automatic inspection function module can check the matching information of each part in the target matching parts list one by one to obtain the interference clearance inspection result of each part.

[0020] Compared with the prior art, the bill of materials database provided in this embodiment is used to generate a model assembly data table according to the system configuration request when receiving the system configuration request of the vehicle; the automatic assembly function module is used to determine the whole vehicle model according to the model assembly data table, so as to realize the automatic assembly of the whole vehicle model; further, the inspection rule database is used to optimize the preset matching parts list according to the whole vehicle model to obtain the target matching parts list; the automatic inspection function module is used to obtain the interference clearance inspection result of each part according to the matching information of each part in the target matching parts list; thus, the parts of the whole vehicle model can be automatically inspected by the automatic inspection function module, without the need for manual repeated verification operations on each part, thereby reducing human resources and time and improving efficiency.

[0021] like Figure 2 As shown, the apparatus 100 may include a model storage database 105 and an inspection result database 106, wherein, in some embodiments of the present invention, the model assembly data table includes a parts bill of materials and a physical model number and an interface model number corresponding to the parts bill of materials; the apparatus further includes a model storage database 105; Model storage database 105, used to determine the physical model and the interface model according to the physical model number and the interface model number corresponding to the parts bill of materials; The automatic assembly function module 102 is also used to call the physical model and the interface model.

[0022] In a specific embodiment of the present invention, the model assembly data table may include the technical characteristics of parts and components, the bill of materials of parts and components, and the physical model number and interface model number corresponding to the bill of materials of parts and components. The model storage database may store many physical models and many interface models. After receiving the model assembly data table, the model storage database may determine the corresponding physical model and interface model according to the physical model number and interface model number in the bill of materials of parts and components, and the automatic assembly function module may call the physical model and the interface model.

[0023] In some embodiments of the present invention, Figure 3 As shown, the model storage database 105 includes a model storage unit 1051 and a level determination unit 1052; the interface model includes multiple levels of location information; The model storage unit 1051 is used to store multiple physical models and multiple interface models, and when receiving the parts and materials list, determine the corresponding physical model and interface model according to the physical model number and the interface model number; the physical model and the interface model are in a one-to-many relationship; The level determination unit 1052 is used to determine the target level position corresponding to the interface model according to the physical model.

[0024] In a specific embodiment of the present invention, the interface model may include multiple hierarchical position information, and the model storage unit may store multiple physical models and multiple interface models. These models may be multiple physical models and multiple interface models established by staff in the initial stage of vehicle design through the modeling standard of automatic electric equipment and the TOP-DOWN design principle. The same type of physical models are classified and applied according to the differences in the technical characteristics of the parts. The same physical model corresponds to multiple interface models due to the overall layout design of the top layer of the vehicle and the layout design of various systems such as cooling and oil supply, that is, the physical model and the interface model are in a one-to-many relationship. Each interface model contains multiple hierarchical position information, so that after the model storage unit receives the bill of materials of the parts, the corresponding physical model and interface model can be determined according to the physical model number and the interface model number in the bill of materials of the parts. The hierarchical determination unit can locate the target hierarchical position corresponding to the physical model according to the multiple hierarchical position information contained in each interface model, wherein the target hierarchical position can be the position where the interface model is assembled in the physical model. The interface model is designed and arranged by the staff according to the top-down principle, while taking into account standardization and modularization, so as to improve the layout requirements of vehicles in different market segments under the vehicle platform. Subsequent new models can still be added to the model storage database for call within the modeling standard framework.

[0025] In some embodiments of the present invention, Figure 4As shown, the model assembly data table also includes component assembly rules; the automatic assembly function module 102 includes a calling unit 1021 and a subassembly unit 1022; The calling unit 1021 is used to call the physical model and the interface model according to the parts and materials list; The subassembly unit 1022 is used to perform system-level subassembly of the physical model and the interface model according to the component assembly rules and the target hierarchical positions to obtain a complete vehicle model.

[0026] In a specific embodiment of the present invention, the model assembly data table may also include parts assembly rules, and the automatic assembly function module 102 may include a calling unit 1021 and a subassembly unit 1022. The calling unit 1021 may call the physical model and the interface model in the model storage database 105 after receiving the parts bill of materials. The subassembly unit 1022 may perform system-level subassembly of the physical model and the interface model according to the called physical model and the interface model, and the corresponding parts assembly rules and the target hierarchical position, and finally automatically combine and assemble them into a whole vehicle model without relying on manual simulation of assembly positioning.

[0027] In some embodiments of the present invention, the automatic assembly function module 102 further includes an assembly judgment unit 1023; The assembly judgment unit 1023 is used to output a problem list when the model states of the physical model and the interface model are inconsistent with the model states in the model assembly data table during the process of the subassembly unit performing system-level subassembly of the physical model and the interface model.

[0028] In a specific embodiment of the present invention, the assembly judgment unit 1023 can judge the model status during the system-level subassembly of the physical model and the interface model by the subassembly unit 1022. When the model status of the physical model and the interface model is inconsistent with or even missing from the model status in the model assembly data table, an early warning will be issued and a problem list will be output. If they are consistent, it means there is no problem.

[0029] In some embodiments of the present invention, Figure 5 As shown, the inspection rule database 103 includes a list setting unit 1031, a standard determination unit 1032 and a list optimization unit 1033; The list setting unit 1031 is used to generate a matching parts list according to all vehicle configuration combinations in the historical process; The standard determination unit 1032 is used to determine the inspection and judgment standard corresponding to each part according to the matching parts list; The list optimization unit 1033 is used to set a correlation judgment mechanism, determine the change area according to the whole vehicle model, and exclude unchanged and irrelevant parts in the matching parts list according to the correlation judgment mechanism and the change area to obtain a target matching parts list.

[0030] In a specific embodiment of the present invention, the inspection rule database 103 may include a list setting unit 1031, a standard determination unit 1032 and a list optimization unit 1033. The list setting unit may be configured by the staff on all vehicles on the existing technical platform to form a list of paired parts. The standard determination unit may determine the inspection and judgment standard corresponding to each part according to the list of paired parts, so that a large number of paired parts that do not need to be analyzed and inspected may be optimized by the list optimization unit. For example, the front bumper and the rear taillight of the vehicle are located at the front and the rear of the vehicle, respectively. There is no necessity for interference clearance inspection in the vehicle layout, thereby reducing the amount of model inspection and analysis data. Optionally, by collecting market segment information of vehicle models, such as tractors, trucks, special vehicles, etc., the inspection and judgment scope may be narrowed and the list of paired parts may be further optimized. A correlation judgment mechanism may also be set up to determine the change area of ​​the whole vehicle model through the vehicle adaptability development plan, so that the unchanged and irrelevant parts in the list of paired parts may be excluded according to the correlation judgment mechanism and the change area. For example, this expansion vehicle development is only for the rear of the vehicle, and there are multiple part changes or position adjustments at the rear. These rear changes are irrelevant to the system components in the front and middle areas of the vehicle. Therefore, the expanded vehicle can exclude the front and middle area system components, greatly compressing the matching parts list, thereby obtaining an optimized target matching parts list.

[0031] In some embodiments of the present invention, the apparatus further comprises an inspection result database 106; The inspection result database 106 is used to store the historical vehicle model pairing results.

[0032] In a specific embodiment of the present invention, the inspection result database 106 can store the pairing results of the whole vehicle model in the historical data to facilitate the subsequent inspection of the pairing results, thereby reducing the inspection process.

[0033] In some embodiments of the present invention, Figure 6 As shown, the automatic inspection function module 104 includes a comparison unit 1041 and an inspection unit 1042; The comparison unit 1041 is used to compare the pairing information of each part in the target pairing parts list with the part pairing information of the pairing results in the inspection result database, and when there is a first part with consistent pairing information, the interference clearance inspection result of the first part is called from the inspection result database; The inspection unit 1042 is used to determine a second part whose pairing information is inconsistent in the target pairing part list, inspect the second part, and obtain an interference clearance inspection result of the second part.

[0034] In a specific embodiment of the present invention, the automatic inspection function module 104 may include a comparison unit 1041 and an inspection unit 1042. After receiving the target matching parts list, the comparison unit 1041 may compare the matching information of each part in the target matching parts list with the part matching information of the matching results of the historical vehicle model stored in the inspection result database, and determine whether there is a physical model, interface model, model version and other information in the target matching parts list that is completely consistent with the part matching information recorded in the inspection result database. If there is a first part with consistent matching information, it means that the first part has not changed, and the detection result of the corresponding part matching information can be directly called from the historical vehicle model. The remaining inconsistent matching parts, i.e., the second parts, can also be determined, and then the second parts can be checked one by one to obtain the interference gap inspection result of each second part.

[0035] In some embodiments of the present invention, the inspection result database 106 includes a result storage unit; The result storage unit is used to store the interference clearance inspection result of the second part, and determine the target inspection judgment standard of the second part according to the inspection judgment standard in the standard determination unit, and judge whether the interference clearance inspection result of the second part meets the target inspection judgment standard. If so, it is determined that the second part has passed the inspection, if not, the rectification information is output.

[0036] In a specific embodiment of the present invention, the result storage unit can store the interference clearance inspection results, screenshots and part-related information of each second part, and can also store target matching parts list, matching parts physical model, matching parts interface model, model version, inspection results, screenshots and other information. Then, each second part can determine the corresponding target inspection judgment standard through the inspection judgment standard in the standard determination unit, and then it can be judged whether the interference clearance inspection result of the second part meets the target inspection judgment standard. If so, it means that the second part has passed the inspection. If not, the rectification information is output to the staff. After the rectification is qualified, the new model information, inspection results and screenshots will be updated for reference. By fully recording the matching parts information, most of the model interference clearance inspection work can be reduced by table lookup and comparison. In the increasingly standardized and modular vehicle development platform, the part reuse rate is high and the efficiency is more obvious.

[0037] When the automatic assembly function module of the embodiment of the present invention performs automatic assembly according to the assembly data table, when it detects that the model state is inconsistent with the assembly data table or even missing, it will issue an early warning and provide a problem list, thereby avoiding insufficient interference clearance inspection of the area where the missing parts belong; through the modeling standard of automatic electrical equipment and the TOP-DOWN design principle, it guides designers to establish physical models and interface models in the early stage of vehicle design, without referring to the assembly relationship of historical models, and without relying on assembly engineers to manually complete the simulated assembly. The automatic assembly function module can automatically complete the assembly of the whole vehicle based on the physical model, interface model and assembly rules (level, priority); by pre-analyzing all vehicle configuration combinations, the An optimized list of paired parts is generated, and paired parts that do not need to be analyzed and inspected are excluded, thereby reducing the amount of model inspection and analysis data; vehicle segment market inspection rules, such as tractors, trucks, special-purpose vehicles, etc., are selected in the inspection rule database according to the instantiated vehicle model information, which can narrow the scope of this inspection and judgment, further optimize the list of paired parts, and reduce the amount of inspection and analysis data; a model correlation pairing area judgment mechanism is established, and the unchanged and irrelevant system components are further excluded through the change area of ​​the vehicle adaptive development plan, thereby reducing the scale of paired parts inspection and improving inspection efficiency; the inspection result database can reduce most of the model interference gap inspection work by fully recording the paired parts information through table lookup and comparison.

Specific examples are used in this article to illustrate the principles and implementation methods of the present invention.
