[0032] Figure 1 A schematic flow chart of a method for designing a foot space for rear passengers in a vehicle according to an embodiment of the present application is shown.
[0033] The method can be applied to a terminal device or a server, wherein the terminal device may include but is not limited to one or more of a smart phone, a tablet computer, a portable computer, and a desktop computer; the server may be a physical server or a cloud server.
[0034] Please refer to Figure 1 The method for designing the foot space for rear passengers of a vehicle at least includes steps S110 to S150, which are described in detail as follows (hereinafter, the method is described by taking the application of the method to a terminal device as an example, hereinafter referred to as "terminal"):
[0035] In step S110 , according to a design request for a rear passenger's foot space of a target vehicle type, an occupant human body model corresponding to the target vehicle type is determined.
[0036] In this embodiment, the target vehicle model may be a vehicle model specified by a designer. When the designer needs to design the footwell for the rear passengers, the designer may pre-specify a vehicle model as the target vehicle model, and then design the footwell for the rear passengers for the target vehicle model. It should be understood that the vehicle body structure data of different vehicle models may be the same or different, so the rear passenger footwell design data obtained by design may be the same or different.
[0037] In one example, an embodiment of the present application may provide a vehicle model selection interface, which may include several vehicle model options. Designers may browse vehicle models through the vehicle model selection interface and select one or more vehicle models as target vehicle models.
[0038] When the designer determines the target vehicle model in the vehicle model selection interface, a corresponding footwell design request can be generated according to the determined target vehicle model, and the footwell design request can include identification information of the target vehicle model. After receiving the footwell design request, the terminal can parse the footwell design request to extract the identification information of the target vehicle model.
[0039] Then, the terminal can determine the occupant human body model corresponding to the target vehicle model according to the identification information of the target vehicle model. In one example, a person skilled in the art can pre-set a correspondence table between vehicle models and occupant human body models, and the terminal can query the correspondence table according to the identification information of the target vehicle model, thereby determining the occupant human body model corresponding to the target vehicle model. It should be noted that the occupant human body models corresponding to different vehicle models can be the same or different. For example, most vehicle models can correspond to a universal occupant human body model, while a small number of vehicle models can correspond to another occupant human body model due to different applicable objects or different vehicle positioning.
[0040] It should be understood that each passenger mannequin should include the size information of each part of itself, so as to simulate the riding experience of real passengers on the target vehicle model. Taking the foot space design as an example, the passenger mannequin should include the size information of the width and length of the sole of the foot. In one example, the passenger mannequin can be a SAE dummy model.
[0041] Please continue to refer to Figure 1 In step S120, parameter information of the foot movable space corresponding to the occupant human body model is determined according to the foot size information of the occupant human body model.
[0042] In this embodiment, after determining the occupant human body model corresponding to the target vehicle model, the terminal can obtain the foot size information of the occupant human body model. It should be understood that when designing the foot space, in addition to providing space for the feet of the rear passengers, it is also necessary to provide space for their feet to move, such as extending the feet forward or retracting them. Therefore, the terminal can determine the parameter information of the foot movable space required by the occupant human body model based on the foot size information of the occupant human body model.
[0043] In step S130 , a corresponding footwell geometry is established according to the parameter information.
[0044] In this embodiment, after determining the parameter information of the foot movable space, the terminal may construct a corresponding foot space geometry, that is, the terminal may visualize the foot movable space and convert it from a parameter form to a spatial geometry form.
[0045] In step S140 , the foot well geometry is aligned with the occupant body model according to a predetermined rule.
[0046] In this embodiment, after the foot movable space is converted into the corresponding foot space geometry, the foot space geometry needs to be aligned with the occupant human body model on the target vehicle model, so that the designer can clearly know the specific position of the foot space geometry on the target vehicle model. Those skilled in the art can pre-set a predetermined rule based on prior experience to align the foot space geometry, and the terminal can read and align the foot space geometry with the occupant human body model according to the predetermined rule.
[0047] In one example, the predetermined rule may include at least one of the following:
[0048] Adjusting the distance between the bottom surface of the footwell geometric body and the bottom line of the foot of the occupant human body model to a predetermined distance, and the bottom line of the foot of the occupant human body model is located above the bottom surface of the footwell geometric body;
[0049] aligning a mid-line of symmetry of the footwell geometry with a heel point of the occupant human body model;
[0050] A heel line of the foot well geometry is aligned with a heel point of the occupant human body model.
[0051] In this embodiment, the terminal may first adjust the height of the footwell geometry, that is, adjust the distance between the bottom surface of the footwell geometry (i.e., the bottom surface of the foot) and the bottom line of the foot of the occupant human model to a predetermined distance (e.g., 6 mm, etc.), the predetermined distance being the distance in the vertical direction, and the bottom line of the foot of the occupant human model is located above the bottom surface of the footwell geometry. Figure 2As shown, the terminal can align the middle symmetry line of the footwell geometry and the heel line with the heel point of the occupant human body model.
[0052] By adjusting according to the above predetermined rules, the footwell geometry can be aligned with the feet of the occupant human body model on the target vehicle model to ensure the effectiveness of the subsequent vehicle body structure design.
[0053] Please continue to refer to Figure 1 In step S150, data information of the aligned foot well geometry is exported, and the data information is associated with the occupant body model to obtain target design data.
[0054] In this embodiment, after aligning the footwell geometry with the occupant human body model, the terminal can export the data information of the aligned footwell geometry, for example, it can export it as data in a predetermined format, and associate the exported data information with the occupant human body model, so as to obtain target design data. In one example, the terminal can associate the exported data information with the heel point of the occupant human body model, that is, establish an association relationship between the data information and the heel point position of the occupant human body model, to ensure that the footwell is accurately aligned with the actual position of the rear occupant's feet in subsequent simulations and tests, so as to more realistically reflect the foot position of the rear occupant when sitting.
[0055] It also helps maintain data consistency across different design phases and test environments, which is critical for cross-team collaboration and data sharing.
[0056] In some embodiments of the present application, the movable space for the foot includes a foot placement space and a foot expansion space;
[0057] Determining parameter information of the foot movable space corresponding to the occupant human body model according to the foot size information of the occupant human body model includes:
[0058] Determining corresponding parameter information of the foot placement space according to the foot size information of the occupant human body model;
[0059] According to the target vehicle model, querying a preset table of correspondence between the vehicle model and the variable value of the foot telescopic space, wherein the variable value of the foot telescopic space is used to represent the telescopic range of the heels of the rear passengers;
[0060] Determining parameter information of the foot expansion and contraction space corresponding to the passenger human body model according to the query result;
[0061] The parameter information of the foot movable space corresponding to the occupant human body model is determined according to the parameter information of the foot placement space and the parameter information of the foot retractable space.
[0062] In this embodiment, if Figure 2 and Figure 3 As shown, the foot movable space includes a foot placing space and a foot expansion space. The foot placing space is located in front of the foot expansion space. The foot placing space can be used to limit the maximum distance that the feet of the rear passengers can extend, and the foot expansion space can be used to limit the movable range of the heels of the rear passengers.
[0063] After determining the foot size information of the occupant body model, the terminal can determine the parameter information of the corresponding foot placement space. For example, the terminal can determine the length of the foot placement space based on the length of the sole of the foot, and the length can be slightly larger than the length of the sole (for example, the sole length plus a predetermined value for determination). The terminal can also determine the width of the foot placement space based on the width of the sole of the foot, and the width can be slightly larger than twice the width of the sole, and so on, thereby ensuring the rationality of the foot placement space setting.
[0064] Next, the terminal can query the pre-set table of correspondences between vehicle types and variable values of foot telescopic space according to the target vehicle type, wherein the variable value of foot telescopic space can be used to characterize the telescopic range of the heels of the rear passengers, that is, the variable value of foot telescopic space can be the length of the foot telescopic space. It should be understood that the body structures of different vehicle types may be the same or different, so the space available for foot movement in different vehicle types may also be different. Therefore, those skilled in the art can determine the table of correspondences between vehicle types and variable values of foot telescopic space according to prior experience, so as to query and use it when designing the foot space, thereby improving the efficiency of foot space design.
[0065] The terminal can determine the parameter information of the foot expansion space corresponding to the occupant human body model according to the query result, and then the terminal can determine the parameter information of the corresponding foot movable space according to the determined parameter information of the foot placement space and the parameter information of the foot expansion space, for example, the length of the foot placement space can be added to the length of the foot expansion space to obtain the length of the foot movable space, etc. In this way, the rationality of the determined parameter information of the foot movable space can be guaranteed.
[0066] Based on the foregoing embodiments, in some embodiments of the present application, after associating the data information with the occupant human body model to obtain target design data, the method further includes:
[0067] According to the received rear passenger foot space design request for the new target vehicle model, querying the corresponding relationship table between the vehicle model and the variable value of the foot telescopic space;
[0068] Determine, according to the query result, parameter information of the foot telescopic space corresponding to the new target vehicle model;
[0069] According to the parameter information of the foot telescopic space corresponding to the new target vehicle model, the historically generated target design data is updated to obtain the target design data corresponding to the new target vehicle model.
[0070] In this embodiment, when faced with a universal passenger body model, when designing the foot space for rear passengers of a new target vehicle model, the terminal can determine the identification information of the new target vehicle model based on the corresponding foot space design request, and query the correspondence table between the aforementioned vehicle model and the variable value of the foot telescopic space to determine the parameter information of the foot telescopic space corresponding to the new target vehicle model.
[0071] Then, the terminal can directly replace the parameter information of the foot expansion and contraction space in the historically generated target design data corresponding to the same occupant body model according to the newly determined parameter information of the foot expansion and contraction space, so as to update the historically generated target design data and obtain the design data corresponding to the new target vehicle model.
[0072] Therefore, there is no need to determine parameter information of the foot placement space, which improves the design efficiency of the foot space design and increases the scope of application of the foot space design method provided in the embodiment of the present application.
[0073] In other embodiments of the present application, determining parameter information of the foot movable space corresponding to the occupant human body model according to the foot size information of the occupant human body model includes:
[0074] The foot size information of the occupant body model and the target vehicle model are input into a pre-trained foot activity space determination model, so that the foot activity space determination model outputs parameter information of the foot activity space corresponding to the occupant body model, wherein the foot activity space determination model is trained by training data including foot space requirements corresponding to different vehicle models when carrying occupant body models of different sizes.
[0075] In this embodiment, a person skilled in the art may also pre-construct a foot activity space determination model and train it using corresponding training data, wherein the training data may include the corresponding foot space requirements when different vehicle models are equipped with passenger mannequins of different sizes. Thus, after training, the foot activity space determination model may output corresponding parameter information of the rear passenger's foot activity space according to the input passenger mannequin foot size information and vehicle model information. Thus, by constructing and training the foot activity space determination model, the design efficiency and rationality of the foot space design may be improved.
[0076] Based on the above embodiment, in one embodiment of the present application, the method further includes:
[0077] The foot activity space determination model is optimized according to feedback information from designers or rear passengers on the foot activity space.
[0078] That is to say, the terminal can also receive feedback information on the foot activity space proposed by designers after simulation or the actual riding experience of rear passengers, and then adjust the foot activity space determination model based on the feedback information to continuously optimize the model and improve the accuracy of the model output results.
[0079] In some embodiments of the present application, after associating the data information with the occupant human body model to obtain target design data, the method further includes:
[0080] In response to a request for viewing the target design data, obtaining vehicle body structure data corresponding to the target vehicle model;
[0081] The target design data is visualized based on the vehicle body structure data, wherein the visualization includes static and / or dynamic display of the feet of the occupant human model within a corresponding foot movable space in the vehicle body structure corresponding to the target vehicle model.
[0082] In this embodiment, the embodiment of the present application also provides a display interface. After receiving a designer's request to view the target design data, the terminal can obtain the body structure data corresponding to the target vehicle model, especially the rear body structure data.
[0083] Then, based on the vehicle body structure data, the terminal can model the target vehicle model and visualize the target design data, wherein the visualization display can include static display and / or dynamic display of the feet of the occupant human model in the corresponding foot movable space in the vehicle body structure corresponding to the target vehicle model. The static display can be the static state of the feet of the occupant human model at different positions in the foot movable space, and the dynamic display can be the motion state of the feet of the occupant human model in the foot movable space.
[0084] Therefore, designers can determine whether the designed foot space will interfere with the current structure of the target vehicle based on the visual display of the target design, so as to make adaptive improvements to the body structure of the target vehicle.
