Description

Technical Field

[0001] This invention relates to the field of vehicle simulation modeling technology, and in particular to a method, apparatus, electronic device and storage medium for modeling a vehicle engine compartment. Background Technology

[0002] Vehicle simulation software is typically used for analyzing vehicle design parameters and modeling vehicles, thereby shortening the design and development cycle and reducing production costs through vehicle modeling.

[0003] Currently, in simulation calculations, 3D calculation software such as PowerFlow or StarCCM+ requires at least 10 working days for a skilled simulation engineer to calculate the allowable ambient temperature for vehicle thermal equilibrium, including pre-processing modeling, software modeling, and platform calculation, assuming sufficient mesh outsourcing and licenses. The pre-processing of the 3D model takes up most of the time, resulting in a long modeling time.

[0004] To address the aforementioned issues, it is necessary to improve the modeling methods for vehicle components. Summary of the Invention

[0005] This invention provides a vehicle engine compartment modeling method, apparatus, electronic device, and storage medium to solve the problem of long modeling time when modeling vehicle engine compartments using existing simulation modeling software.

[0006] In a first aspect, embodiments of the present invention provide a vehicle engine compartment modeling method, including:

[0007] Identify at least one component to be modeled in the engine compartment of the target vehicle, and the component type corresponding to each component to be modeled; the component type includes a first component type that has an angular deviation from the actual vehicle engine compartment component, or a second component type that does not have an angular deviation from the actual vehicle engine compartment component;

[0008] Based on the modeling method to be used corresponding to the component type, the corresponding component to be modeled is modeled to obtain the component to be used.

[0009] Based on the component association relationship between at least one component to be used, a target vehicle cabin model corresponding to the target vehicle cabin is constructed.

[0010] Secondly, embodiments of the present invention also provide a vehicle engine compartment modeling apparatus, comprising:

[0011] The component type determination module is used to determine at least one component to be modeled in the engine compartment of the target vehicle, and the component type corresponding to each component to be modeled; the component type includes a first component type that has an angular deviation from the actual vehicle engine compartment component, or a second component type that does not have an angular deviation from the actual vehicle engine compartment component;

[0012] The component to be used determination module is used to perform modeling processing on the corresponding component to be modeled based on the modeling method to be used corresponding to the component type, so as to obtain the component to be used.

[0013] The cabin model determination module is used to construct a target vehicle cabin model corresponding to the target vehicle cabin based on the component association relationship between at least one component to be used.

[0014] Thirdly, embodiments of the present invention also provide an electronic device, comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the vehicle cabin modeling method according to any embodiment of the present invention.

[0018] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the vehicle cabin modeling method described in any embodiment of the present invention.

[0019] The technical solution of this invention, by determining at least one component to be modeled in the engine compartment of a target vehicle and the component type corresponding to each component, and by inputting the corresponding component parameters in the editing control of the target editing interface, can extract the corresponding component to be modeled from the engine compartment of the target vehicle, and determine the component type corresponding to each component to be modeled based on the vehicle configuration information of the target vehicle. Further, based on the modeling method corresponding to the component type, the corresponding component to be modeled is modeled to obtain the component to be used. For the component to be modeled of the first component type, the simulation modeling software can model the component to be modeled by its center point and boundary points to obtain the corresponding component to be used. For the component to be modeled of the second component type, in order to make the modeled component to be used closer to the component to be modeled in the actual engine compartment, the tilt angle corresponding to the component to be used needs to be adjusted to obtain a component to be used with the same tilt angle as the corresponding component to be modeled. Based on this, based on the component association relationship between at least one component to be used, a target vehicle engine compartment model corresponding to the target vehicle engine compartment is constructed, so that the corresponding target vehicle engine compartment model can be directly retrieved in different coordinate systems without needing to perform multiple modeling in different coordinate systems. This solution addresses the issues of inaccurate modeling results or excessive modeling time when modeling vehicle engine compartments using existing simulation modeling software, achieving the effect of improving modeling efficiency while accurately modeling each vehicle component.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0028] Example 1

[0029] Figure 1 The flowchart of a vehicle engine compartment modeling method provided in Embodiment 1 of the present invention is applicable to situations where the modeling process is performed by calling the corresponding modeling processing method according to the type of vehicle components in the vehicle engine compartment, so as to improve the modeling efficiency while accurately modeling each vehicle component. The method can be executed by a vehicle engine compartment modeling device, which can be implemented in hardware and / or software. The vehicle engine compartment modeling device can be configured in a computing device that can execute the vehicle engine compartment modeling method.

[0030] like Figure 1 As shown, the method includes:

[0031] S110. Determine at least one component to be modeled in the engine compartment of the target vehicle, and the component type corresponding to each component to be modeled.

[0032] In this technical solution, the description is from the perspective of the vehicle driver. The target vehicle's engine compartment can be understood as including the area below the driver's cab floor, inside the two side wheels, the front bulkhead, and any obstructions that the air vents can reach, as well as the area above the ground. The target vehicle's engine compartment may include multiple vehicle components. The components to be modeled can be understood as the vehicle components in the target vehicle's engine compartment that need to be modeled, such as the cooling system, radiator, vents, and front bulkhead shielding shell installed in the target vehicle.

[0033] It should be noted that the types of vehicle components in the target vehicle's engine compartment are divided into two main categories: the first type of component that does not have an angular deviation from the actual vehicle engine compartment components, and the second type of component that does have an angular deviation from the actual vehicle engine compartment components.

[0034] To shorten the development cycle and minimize development costs, vehicle development typically begins with vehicle modeling, which is then used to simulate the actual vehicle. Therefore, the resulting vehicle model should be as close to the real vehicle as possible. For example, the dimensions of each modeled component should match the corresponding components in the actual vehicle, and the relative positions of these components should also correspond to their respective positions in the actual vehicle. In other words, a higher degree of matching between the vehicle model and the actual vehicle is more beneficial for subsequent vehicle function development, such as calculating the vehicle's thermal balance.

[0035] Specifically, after determining the target vehicle's engine compartment, the vehicle components that need to be modeled in the target vehicle's engine compartment are taken as components to be modeled, and the component types corresponding to each component to be modeled are determined, so as to determine the modeling processing method corresponding to each component type, and then modeling is performed.

[0036] Optionally, determining at least one component to be modeled in the target vehicle's engine compartment, and the component type corresponding to each component to be modeled, includes: inputting corresponding component parameters in at least one editing control in the target editing interface, and extracting the corresponding component to be modeled from the target vehicle's engine compartment based on at least one component parameter; for each component to be modeled, determining the component type corresponding to the current component to be modeled based on the target mapping table.

[0037] The target editing interface can be understood as the control interface of the modeling software used to model the engine compartment of the target vehicle. The target editing interface includes at least one editing control for inputting modeling parameters corresponding to the parts to be modeled. The target mapping table includes at least one part to be modeled, and the part type corresponding to each part.

[0038] Specifically, the target vehicle's engine compartment includes different component types. In this technical solution, the component types are mainly divided into a first component type that has no angular deviation from the actual vehicle engine compartment components, and a second component type that has an angular deviation from the actual vehicle engine compartment components. In practical applications, when it is necessary to model the target vehicle's engine compartment, the component parameters corresponding to the component to be modeled can be entered in the target display interface to retrieve the corresponding component to be modeled based on the input component parameters. Furthermore, the component type corresponding to the current component to be modeled can be determined according to the target mapping table.

[0039] S120. Based on the modeling method corresponding to the component type, perform modeling processing on the corresponding component to be modeled to obtain the component to be used.

[0040] In this technical solution, different modeling methods are required for different component types. The modeling method to be used can be understood as the modeling method corresponding to the component type after the component type is determined. The component to be used can be understood as the modeling file after the component to be modeled is modeled. For example, if component A is modeled, then the modeling file A corresponding to component A is the component to be used.

[0041] Optionally, the component type is the first component type. Based on the modeling method to be used corresponding to the component type, the corresponding component to be modeled is modeled to obtain the component to be used, including: determining the center point to be determined of the component to be modeled, and at least one boundary point to be used associated with the component to be modeled; and modeling the component to be modeled according to the coordinate information of the center point to be determined and the coordinate information of the boundary points to be used, to obtain the component to be used.

[0042] In this context, the center point to be determined can be understood as the geometric center point of the component to be modeled. For example, if the component to be modeled is a cuboid with a length of 5cm, a width of 3cm, and a height of 1cm, and the face corresponding to the length of 5cm and the width of 3cm is taken as the base A, then the center point to be determined for this component is the geometric center point of the base A, that is, the center point of the two oblique lines on the base A. Taking the base A as an example again, the boundary points to be used can be understood as points on the boundary of the base A. It should be noted that for regular geometric shapes, for ease of modeling, vertices on the base A can be taken as the boundary points to be used. For irregular geometric shapes, the boundary points to be used include all points on the base A.

[0043] In the actual modeling process, if the component to be modeled is of the first component type, that is, there is no angular deviation between the component to be modeled and the actual vehicle engine compartment component, it is necessary to determine the center to be determined for the component to be modeled, as well as at least one boundary point to be used associated with the component to be modeled. For example, the component to be modeled of the first component type can be a ventilation entity or ventilation hole in the target vehicle engine compartment. The geometric center point of the preset bottom surface of the component to be modeled is used as the center to be determined. When determining the boundary points to be used, it is first necessary to determine whether the component to be modeled is a regular geometry. If so, the boundary points corresponding to the vertices of the component to be modeled can be obtained as at least one boundary point to be used associated with the component to be modeled; otherwise, all points on the boundary of the component to be modeled need to be used as boundary points to be used. Furthermore, taking CERO software as an example, CERO software uses a vehicle coordinate system. Under the vehicle coordinate system, the coordinate information of the center point to be determined, as well as the coordinate information of the boundary points to be used corresponding to each boundary point to be used, can be determined.

[0044] Optionally, if the component type of the component to be modeled is the second component type, then the tilt angle to be determined corresponding to the component to be used is determined according to the vehicle configuration information of the target vehicle; the tilt angle of the component to be used is adjusted based on the tilt angle to obtain the component to be used that is consistent with the tilt angle of the corresponding component to be modeled.

[0045] It should be noted that in traditional simulation modeling software, when modeling a component of type two, there is an inherent angular deviation between the resulting usable component and the actual vehicle component. This is because traditional simulation modeling software cannot simulate a certain tilt angle when the usable component is tilted relative to the vehicle coordinate system, resulting in the modeled usable component being perpendicular to the vehicle coordinate system. In other words, there will be a certain angular deviation between the usable component and the actual vehicle component; that is, the tilt angle needs to be determined.

[0046] It is understandable that for different types, brands, and models of vehicles, when the part to be modeled is a second part type, the tilt angle of the part to be modeled in reality can be determined through the corresponding vehicle configuration information, and the tilt angle to be determined for the corresponding part to be used can be determined based on the tilt angle of the part to be modeled.

[0047] Based on this, when modeling a component of the second component type, such as a cooling system or radiator assembly in a target vehicle, this technical solution can find the corresponding tilt angle to be determined in the vehicle configuration information based on the component identifier corresponding to the component to be modeled. After modeling the component of the second component type, the angle of the component to be used is adjusted based on the tilt angle to be determined, resulting in a component to be used with the same tilt angle as the component to be modeled. For example, if the tilt angle of the component to be modeled is 5° clockwise, then the tilt angle to be determined for the corresponding component to be used is adjusted to be 5° clockwise.

[0048] S130. Based on the component association relationship between at least one component to be used, construct a target vehicle cabin model corresponding to the target vehicle cabin.

[0049] In this technical solution, the component association mainly refers to the relative positional relationship between each component to be used. Optionally, based on the component association between at least one component to be used, a target vehicle cabin model corresponding to the target vehicle cabin is constructed, including: determining the actual vehicle cabin components corresponding to at least one component to be used, and determining the relative positional information between each actual vehicle cabin component; determining the component association between at least one component to be used based on the relative positional information, so as to construct the target vehicle cabin model based on target modeling software.

[0050] Specifically, corresponding components to be used are constructed for each component to be modeled, and the target vehicle's engine compartment is constructed based on these components. To ensure that the modeled target vehicle engine compartment is closer to the actual vehicle engine compartment, the relative position information between the corresponding components to be used needs to be determined based on the relative positional relationships between the components in the actual vehicle engine compartment.

[0051] For example, the target vehicle's engine compartment includes three components to be modeled. The components to be used in the vehicle coordinate system for each component are determined, and their corresponding coordinate positions are extracted. Furthermore, based on the coordinate positions of each component in the vehicle coordinate system, the relative positional relationships between these three components can be obtained, i.e., the component association relationships between them, so as to construct a target vehicle engine compartment model based on target modeling software.

[0052] The advantage of this setup is that, after determining the relative position information between each component to be used, even when any coordinate system other than the whole vehicle coordinate system is opened, the relative position information between the components to be used corresponding to each component to be modeled in the target vehicle's engine compartment remains unchanged, which improves modeling efficiency. At the same time, it makes the transformation of the target vehicle's engine compartment under different coordinate systems easier, without the need for repeated modeling. In other words, while accurately modeling each component to be used, it shortens the modeling process time and improves modeling efficiency.

[0053] The technical solution of this invention, by determining at least one component to be modeled in the engine compartment of a target vehicle and the component type corresponding to each component, and by inputting the corresponding component parameters in the editing control of the target editing interface, can extract the corresponding component to be modeled from the engine compartment of the target vehicle, and determine the component type corresponding to each component to be modeled based on the vehicle configuration information of the target vehicle. Further, based on the modeling method corresponding to the component type, the corresponding component to be modeled is modeled to obtain the component to be used. For the component to be modeled of the first component type, the simulation modeling software can model the component to be modeled by its center point and boundary points to obtain the corresponding component to be used. For the component to be modeled of the second component type, in order to make the modeled component to be used closer to the component to be modeled in the actual engine compartment, the tilt angle corresponding to the component to be used needs to be adjusted to obtain a component to be used with the same tilt angle as the corresponding component to be modeled. Based on this, based on the component association relationship between at least one component to be used, a target vehicle engine compartment model corresponding to the target vehicle engine compartment is constructed, so that the corresponding target vehicle engine compartment model can be directly retrieved in different coordinate systems without needing to perform multiple modeling in different coordinate systems. This solution addresses the issues of inaccurate modeling results or excessive modeling time when modeling vehicle engine compartments using existing simulation modeling software, achieving the effect of improving modeling efficiency while accurately modeling each vehicle component.

[0054] Example 2

[0055] Figure 2 The flowchart of a vehicle engine compartment modeling method provided in Embodiment 2 of the present invention includes, optionally, obtaining a three-dimensional file corresponding to the target vehicle before determining at least one component to be modeled in the target vehicle engine compartment and determining the component type of each component to be modeled; determining the region to be processed in the three-dimensional file based on at least one boundary parameter; and extracting the target vehicle engine compartment corresponding to the region to be processed from the three-dimensional file.

[0056] like Figure 2 As shown, the method includes:

[0057] S210, Determine the engine compartment of the target vehicle.

[0058] In practical applications, before identifying at least one component to be modeled in the engine compartment of the target vehicle and determining the component type of each component to be modeled, the process also includes acquiring a 3D file to be processed corresponding to the target vehicle; and determining and extracting the processing area in the 3D file based on at least one boundary parameter.

[0059] The 3D file to be processed can be understood as the full-vehicle 3D file corresponding to the target vehicle. The area to be processed can be understood as the engine compartment of the target vehicle.

[0060] Specifically, the 3D file corresponding to the target vehicle is imported into modeling software, such as CERO software, and the processing area in the 3D file is extracted by setting at least one boundary parameter corresponding to the engine compartment of the target vehicle, so as to extract the 3D file corresponding to the engine compartment of the target vehicle from the 3D file.

[0061] For example, in the 3D file to be processed, the closed area formed by the area below the cab floor, above the bottom surface, inside the wheels on both sides of the vehicle, the front bulkhead, and the obstructions that the vehicle's air vents can reach is taken as the target vehicle's engine compartment, and the area to be processed corresponding to the target vehicle's engine compartment is extracted from the 3D file to be processed according to the corresponding boundary parameters.

[0062] S220. Determine at least one component to be modeled in the engine compartment of the target vehicle, and the component type corresponding to each component to be modeled.

[0063] S230. Based on the modeling method corresponding to the component type, perform modeling processing on the corresponding component to be modeled to obtain the component to be used.

[0064] S240. Based on the component association relationship between at least one component to be used, construct a target vehicle cabin model corresponding to the target vehicle cabin.

[0065] Based on this, in order to ensure the accuracy of the target vehicle cabin model, the target vehicle cabin model is converted into a 3D file to be verified, and the target 3D file corresponding to the target vehicle cabin is retrieved; it is determined whether the 3D file to be verified matches the target 3D file; if yes, the modeling result of the target vehicle cabin model is determined to be qualified; if no, the modeling result of the target vehicle cabin model is determined to be unqualified, and the target vehicle cabin is remodeled.

[0066] The 3D file to be verified can be understood as the 3D file corresponding to the engine compartment model of the target vehicle. The target 3D file can be understood as the 3D file used to verify the engine compartment model of the target vehicle.

[0067] Specifically, the 3D file to be verified is verified based on the target 3D file. If the 3D file to be verified matches the target 3D file, the target vehicle engine compartment model is determined to be qualified; otherwise, the target vehicle engine compartment model is determined to be unqualified.

[0068] For example, for a component of the first component type in the target vehicle's engine compartment, if the 3D file to be verified corresponding to the component to be used is consistent with the target 3D file, then the component to be used is determined to be successfully modeled. For a component of the second component type, if the angular deviation between the 3D file to be verified corresponding to the component to be used and the target 3D file is within a preset angular deviation range, then the component to be used is determined to be successfully modeled. When all the components to be used corresponding to the components to be modeled in the target vehicle's engine compartment are successfully modeled, and the relative position information between each component to be used is consistent with the relative position information between the corresponding components to be modeled, then the target vehicle engine compartment model is determined to be successful.

[0069] The technical solution of this invention, by determining at least one component to be modeled in the engine compartment of a target vehicle and the component type corresponding to each component, and by inputting the corresponding component parameters in the editing control of the target editing interface, can extract the corresponding component to be modeled from the engine compartment of the target vehicle, and determine the component type corresponding to each component to be modeled based on the vehicle configuration information of the target vehicle. Further, based on the modeling method corresponding to the component type, the corresponding component to be modeled is modeled to obtain the component to be used. For the component to be modeled of the first component type, the simulation modeling software can model the component to be modeled by its center point and boundary points to obtain the corresponding component to be used. For the component to be modeled of the second component type, in order to make the modeled component to be used closer to the component to be modeled in the actual engine compartment, the tilt angle corresponding to the component to be used needs to be adjusted to obtain a component to be used with the same tilt angle as the corresponding component to be modeled. Based on this, based on the component association relationship between at least one component to be used, a target vehicle engine compartment model corresponding to the target vehicle engine compartment is constructed, so that the corresponding target vehicle engine compartment model can be directly retrieved in different coordinate systems without needing to perform multiple modeling in different coordinate systems. This solution addresses the issues of inaccurate modeling results or excessive modeling time when modeling vehicle engine compartments using existing simulation modeling software, achieving the effect of improving modeling efficiency while accurately modeling each vehicle component.

Figure 3 As shown, the device includes: a component type determination module 310, a component to be used determination module 320, and a cabin model determination module 330.

[0072] The component type determination module 310 is used to determine at least one component to be modeled in the engine compartment of the target vehicle, and the component type corresponding to each component to be modeled; the component type includes a first component type that does not have an angular deviation from the actual vehicle engine compartment component, or a second component type that has an angular deviation from the actual vehicle engine compartment component.

[0073] The component determination module 320 is used to perform modeling processing on the corresponding component to be modeled based on the modeling method corresponding to the component type, so as to obtain the component to be used.

[0074] The cabin model determination module 330 is used to construct a target vehicle cabin model corresponding to the target vehicle cabin based on the component association relationship between at least one component to be used.

[0075] The technical solution of this invention, by determining at least one component to be modeled in the engine compartment of a target vehicle and the component type corresponding to each component, and by inputting the corresponding component parameters in the editing control of the target editing interface, can extract the corresponding component to be modeled from the engine compartment of the target vehicle, and determine the component type corresponding to each component to be modeled based on the vehicle configuration information of the target vehicle.
