DETAILED DESCRIPTION

[0022] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0023] Vehicle height directly affects energy consumption and range performance by influencing factors such as weight and wind resistance. Current vehicle height design relies on a layer-by-layer derivation of dimensions, starting from the ground line and sequentially drawing structures such as the battery, floor, carpet, passenger space, and roof to finally determine the vehicle height line. This process requires manual drawing and adjustment, cannot directly generate complete cross-sections, and does not support parametric modification, resulting in low design efficiency and long iteration cycles. Although related technologies have proposed methods for deriving vehicle height, they still rely on theoretical calculations to verify the rationality of the driver's sitting posture, and cannot directly generate editable vehicle height cross-sections in design software, nor do they have parameter adjustment functions, making it difficult to achieve efficient and rapid design response.

[0024] Therefore, while taking into account the rationality of the internal space layout and design efficiency of electric vehicles, this application provides a method for generating vehicle height information of electric vehicles. By embedding a knowledge engineering module in the electronic device, it automatically associates hard point data in response to user input features and supports interactive adjustment of parameter size features. It triggers the call of vehicle height design drawing software to automatically generate vehicle height information including internal space dimensions. This achieves rapid generation of editable sections while avoiding the problems of low design efficiency and long iteration cycle caused by layer-by-layer derivation, manual drawing and lack of parameter adjustment.

[0025] The following description, with reference to the accompanying drawings, outlines a method, apparatus, electronic device, and medium for generating vehicle height information for electric vehicles according to embodiments of this application. Addressing the issues mentioned in the background art where the vehicle height of electric vehicles requires layer-by-layer derivation and manual drawing, making it impossible to directly generate cross-sections and lacking parameter adjustment support, resulting in low design efficiency, this application provides a method for generating vehicle height information for electric vehicles. This method, based on an embedded knowledge engineering module in an electronic device, automatically associates hard-point data in response to user input features. It also supports adjusting parameter size features in the interactive interface and triggering the invocation of vehicle height design drawing software, automatically generating vehicle height information including internal space dimensions. This avoids the low design efficiency caused by layer-by-layer derivation, manual drawing, and lack of parameter adjustment support, significantly shortening the design cycle and improving design efficiency. Therefore, it solves the problems of low design efficiency caused by the layer-by-layer derivation and manual drawing of vehicle height in related technologies, which prevent direct generation of cross-sections and lack of parameter adjustment support.

[0026] Specifically, Figure 1 This application provides an embodiment of an electric vehicle height information generation method. Flowchart of the method.

[0027] like Figure 1 As shown, the method for generating vehicle height information for this electric vehicle includes the following steps: In step S101, the interactive interface of the electronic device is triggered in response to the user's interactive action.

[0028] It is understandable that an interactive interface refers to the human-computer interaction interface between a user and an electronic device for inputting and outputting information. It can be used to display data and receive user operation instructions.

[0029] In some embodiments, the interactive interface is divided into a first interface area, a second interface area, and a third interface area. The first interface area displays function buttons, and when a function button is triggered, the corresponding content of the function button is displayed in the second interface area. The third interface area displays operation buttons.

[0030] It is understandable that function buttons refer to user interface controls used to trigger specific function modules or page switching; operation buttons refer to controls used to execute specific operation commands; dividing the interactive interface into three areas achieves clear partitioning and collaborative linkage of interface functions, improving the intuitiveness of user operation and interaction efficiency.

[0031] In some embodiments, the function buttons include at least one of a definition button, an input button, a meta input button, a parameter button, a document button, a property button, an output button, and a type button. When the input button is triggered, the second interface area displays an internal component list and a component input list. The internal component list includes user characteristics, and the component input list includes hard point data. The operation buttons include at least one of a modify button, a confirm button, and a cancel button.

[0032] Understandably, the meta-input button is used to trigger the loading of preset feature sets or logical relationship data required for parametric design; the internal component list lists the internal structural features related to the derivation of the vehicle height, including user features, and is used to assist in design input; the component input list lists hard point data items that need to be specified by the user (such as unloaded ground line, wheel center position, etc.) and serves as the baseline input for the vehicle height parametric derivation process; the edit button is used to re-edit the entered user features or hard point data, such as the change / update component button, add button, remove button, replace button, reorder button, etc.

[0033] Specifically, such as Figure 2As shown, the interactive interface is divided into three functional areas: The first interface area has horizontally arranged function buttons for definition, input, parameters, documents, attributes, output, type, and meta-input, used to activate different configuration dimensions; the second interface area dynamically responds to button triggers, such as displaying an internal component list (including user features) and a component input list (including hard point data) when the input button is activated, presenting the target output features and parameter size features in real time and supporting adjustment; the third interface area has operation buttons, which allow users to trigger the embedded knowledge engineering module, thereby calling the vehicle height design drawing software, which automatically generates vehicle height information with internal space dimensions based on hard point data, target output features, or parameter size features, achieving efficient and integrated vehicle height parameterization derivation. At the same time, the intuitive interface layout significantly reduces the user's operating threshold.

[0034] For example, after a user clicks the input button in the first interface area, the second interface area displays an internal component list and a component input list. The internal component list contains some user characteristics, and the component input list contains some hard data items. After the user selects the corresponding item and enters the data, they can use the edit button in the third interface area to re-edit the selected content, or submit the input through the confirmation button to enter the parameter adjustment stage.

[0035] In step S102, user characteristics are input into the interactive interface of the electronic device, hard point data of the electric vehicle are automatically selected based on the user characteristics, target output characteristics and parameter size characteristics are displayed in the interactive interface, and the parameter size characteristics can be adjusted in the interactive interface.

[0036] Among them, user characteristics refer to the reference positions or structural elements related to the passenger space inside the electric vehicle; hard point data refers to the immutable geometric reference elements in the vehicle design; target output characteristics refer to the vehicle height derivation results that need to be generated according to project requirements; and parameter size characteristics refer to the design variables that can be set or adjusted by the user.

[0037] In some embodiments, user features include at least one of the following: roof position, battery, floor sheet metal, carpet, second-row human body, battery surface, floor surface, carpet position, R-point position, battery position, floor position, carpet compression amount, carpet compression surface, roof and vehicle height line, and at least one of the following hard point data: unloaded ground line, unloaded front wheel center, unloaded rear wheel center and ZX plane.

[0038] Understandably, the headliner location refers to its specific position relative to other parts of the vehicle body, affecting passenger headroom; the battery location refers to the battery's installation position within the vehicle body, directly impacting the overall weight distribution and center of gravity; the floor sheet metal refers to the metal sheet of the vehicle floor, involving floor thickness and the gap between it and the battery; the second-row occupants refer to the position of passengers in the second-row seats and their relationship to the vehicle's interior structure, involving ergonomic design; the battery surface refers to the specific location of the battery surface, similar to the battery location but focusing more on the design interface of the battery pack; the floor surface refers to the specific location of the floor surface, used to determine the interior space height; the carpet location refers to the specific location of the carpet within the vehicle, requiring consideration of its relative relationship to the floor and other interior components; the R-point location refers to the seating reference point of the car seat, which in the anatomical model is the hinge point between the torso and the thigh. At the junction of the seat back and seat cushion; carpet compression is the degree to which the carpet is compressed when a passenger sits on the seat, affecting the actual usable vertical space; carpet compression surface is the surface position of the carpet under compression, further refining the concept of carpet position; vehicle height line is the line connecting the ground to the highest point of the roof, a key parameter for measuring the overall vehicle height; unloaded ground line is the baseline line between the ground and the vehicle body when the vehicle is unloaded; unloaded front / rear wheel centers are the specific positions of the front and rear wheel centers when the vehicle is unloaded, used to determine the basic attitude of the vehicle; the ZX plane refers to the longitudinal symmetry reference plane in the vehicle coordinate system, composed of the vehicle's X-axis (forward direction) and Z-axis (vertical direction), used to define the design benchmark for the vehicle's left and right symmetrical structure, and as a reference plane for geometric alignment and hard point data matching during the derivation of vehicle height parameters.

[0039] It should be noted that the battery position is defined based on the unloaded ground line and the unloaded ground clearance; the floor data is defined based on the floor thickness and the gap between the floor and the battery; the carpet data is set based on the carpet thickness; the second-row occupants are set based on the carpet compression and the second-row seat height; the roof data is set based on the second-row headroom and the roof thickness; and the vehicle height line is set based on the roof fixing gap and the roof / skylight thickness.

[0040] Among them, unloaded ground clearance refers to the vertical distance between the lowest point of the chassis and the ground when the vehicle is unloaded; floor thickness refers to the vertical dimension of the vehicle's floor structure itself; floor-to-battery clearance refers to the installation or safety clearance reserved between the lower surface of the vehicle floor and the upper surface of the battery pack; carpet thickness refers to the physical thickness of the carpet material laid on the floor; second-row seat height refers to the height of the second-row seat reference point (R point) relative to the floor or reference surface; second-row headroom refers to the vertical distance from the top of the second-row occupants' heads to the inner surface of the headliner; headliner thickness refers to the vertical dimension of the vehicle's headliner interior structure itself; headliner fixing clearance refers to the fixing clearance reserved between the headliner and the vehicle body structure for installation or sealing; and roof / panorama thickness refers to the vertical dimension of the outer roof panel or panoramic glass structure.

[0041] Specifically, such as Figure 3 As shown, point R is located at the junction of the seat back and the seat cushion, and its vertical height is determined by the thickness of the floor, the thickness of the carpet, and the amount of compression. Based on the location of point R and the setting of the second-row seat height, a human sitting posture model is constructed to check the head and legroom and ensure seating comfort.

[0042] In some embodiments, the target output features are determined based on the data that the project requires to be represented. The target output features include elements, the output name of the elements, and the type. The elements include at least one of the following: ceiling location, battery, floor sheet metal, carpet, R-point location, second-row human body, and vehicle height line. The data that the project requires to be represented includes at least one of the following: battery location, floor data, carpet data, second-row human body, ceiling data, and vehicle height line.

[0043] In step S103, when the knowledge engineering module is triggered by the operation button on the interactive interface, the vehicle height design drawing software is invoked. The vehicle height design drawing software performs the following operation: generating vehicle height information based on at least one of the hard point data, target output features, and parameter size features.

[0044] In some embodiments, generating vehicle height information based on at least one of hard point data, target output features, and parameter size features includes: importing hard point data and parametrically designing a vehicle height line model; selecting hard point data according to the prompts in the parametrically designed vehicle height line model; inputting component features corresponding to the hard point data according to the project requirements of the electric vehicle, and outputting target output features according to user features and parameter size features; extracting the R-point position from the target output features; and if the R-point position in the target output features meets the project requirements, then outputting the vehicle height information from the target output features.

[0045] Among them, the parametric design vehicle height line model refers to a reusable design template built on the vehicle height dimension chain, which includes hard point correlation and parameter-driven logic. It can be instantiated in vehicle height design drawing software and used to automatically generate vehicle height sections. Component features refer to quantifiable structural parameters related to vehicle height design, which are used to drive the parametric design vehicle height line model to generate target output features.

[0046] For example, during the generation of vehicle height information, the position of point R in the target output features is calculated and extracted based on the input parameters. If the position of point R meets the design specifications set by the project, subsequent operations are performed to generate complete vehicle height information including vehicle height lines and dimension annotations. If the position of point R does not meet the project requirements, the vehicle height information output is not triggered, and the user needs to return to adjust the parameters and run the process again.

[0047] In some embodiments, vehicle height information includes vehicle height lines, dimensions, and labeling information, and component features include at least one of the following: unloaded ground clearance, battery height, floor-to-battery clearance, floor thickness, carpet thickness, and second-row seat height.

[0048] Battery height refers to the total thickness or vertical dimension of the electric vehicle's power battery pack in its installed state.

[0049] Specifically, such as Figure 4 As shown, the entire process encompasses the automated generation of vehicle height information based on parameter input, mainly including: importing the unloaded ground line, unloaded front wheel center, unloaded rear wheel center, and ZX plane; importing the template by instantiating it through document insertion; selecting the corresponding geometric elements as prompted and confirming consistent orientation; inputting parameters such as unloaded ground clearance, battery height, floor-to-battery clearance, floor thickness, carpet thickness, and second-row seat height; generating the vehicle height line and adding dimension annotations. This reduces the workload of manual drawing and adjustment of each item and improves design efficiency and accuracy.

[0050] For example, when importing the unloaded ground line, unloaded front wheel center, unloaded rear wheel center, and ZX plane as references, a template is instantiated by inserting a document and named chegao.CATPart. The following steps are performed: check if the direction of the above inputs matches the direction indicated in the template. After confirming the direction matches, key parameters are then input: unloaded ground clearance 180mm, battery height 140mm, floor-to-battery clearance 35mm, floor thickness 3mm, carpet thickness 5mm, and second-row seat height 650mm. Based on these parameters, the R-point position is calculated and verified. Once the requirements are met, the vehicle height line is automatically generated, dimensions are added, and complete vehicle height information is output.

[0051] The method for generating vehicle height information for electric vehicles proposed in this application, based on an embedded knowledge engineering module in the electronic device, automatically associates hard point data with user input features, and supports adjusting parameter size features in the interactive interface to trigger the invocation of vehicle height design drawing software, automatically generating vehicle height information including internal space dimensions. This avoids the problem of low design efficiency caused by layer-by-layer derivation, manual drawing, and lack of parameter adjustment support, significantly shortening the design cycle and improving design efficiency. Therefore, it solves the problems of low design efficiency caused by the need for layer-by-layer derivation and manual drawing of electric vehicle height in related technologies, the inability to directly generate cross-sections, and the lack of support for parameter adjustment.

[0052] Next, referring to the accompanying drawings, an electric vehicle height information generation device according to an embodiment of this application is described.

[0054] like Figure 5 As shown, the vehicle height information generation device 10 for the electric vehicle includes: a response module 100, an input module 200, and a generation module 300.

[0056] In some embodiments, the interactive interface is divided into a first interface area, a second interface area, and a third interface area. The first interface area displays function buttons, and when a function button is triggered, the corresponding content of the function button is displayed in the second interface area.

[0059] In some embodiments, the target output features are determined based on the data that the project requires to be represented. The target output features include elements, the output name of the elements, and the type. The elements include at least one of the following: ceiling location, battery, floor sheet metal, carpet, R-point location, second-row human body, and vehicle height line. The data that the project requires to be represented includes at least one of the following: battery location, floor data, carpet data, second-row human body, ceiling data, and vehicle height line.

[0060] In some embodiments, the generation module is used to: import hard point data and parametrically designed vehicle height line model; select hard point data according to the prompts of the parametrically designed vehicle height line model; input the component features corresponding to the hard point data according to the project requirements of electric vehicles; output target output features according to user features and parameter size features; extract the R-point position in the target output features; if the R-point position in the target output features meets the project requirements, output the vehicle height information in the target output features.

[0061] In some embodiments, vehicle height information includes vehicle height lines, dimensions, and labeling information, and component features include at least one of the following: unloaded ground clearance, battery height, floor-to-battery clearance, floor thickness, carpet thickness, and second-row seat height.

[0062] It should be noted that the foregoing explanation of the method for generating vehicle height information of electric vehicles also applies to the vehicle height information generation device of electric vehicles in this embodiment, and will not be repeated here.

[0063] The electric vehicle height information generation device proposed in this application, based on an embedded knowledge engineering module in the electronic device, automatically associates hard point data with user input features, and supports adjusting parameter size features in the interactive interface to trigger the invocation of vehicle height design drawing software, automatically generating vehicle height information including internal space dimensions. This avoids the problem of low design efficiency caused by layer-by-layer derivation, manual drawing, and lack of parameter adjustment support, significantly shortening the design cycle and improving design efficiency. Therefore, it solves the problems of low design efficiency caused by the need for layer-by-layer derivation and manual drawing of electric vehicle height in related technologies, the inability to directly generate cross-sections, and the lack of support for parameter adjustment.

[0066] Furthermore, electronic devices also include: Communication interface 603 is used for communication between memory 601 and processor 602.

[0069] If the memory 601, processor 602, and communication interface 603 are implemented independently, then the communication interface 603, memory 601, and processor 602 can be interconnected via a bus to complete communication between them.
