[0079] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0080] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0081] Currently, in the vehicle design process, comfort analysis is typically conducted to consider factors such as user comfort and convenience during vehicle use. However, current comfort analyses often focus on the passenger compartment, while checks on the trunk often emphasize whether there is a risk of bumping one's head in the trunk and whether the tailgate design meets the requirements for human accessibility, without analyzing the trunk's interior accordingly. Consequently, parts and buttons installed in the trunk may not meet the requirements for operational comfort.

[0082] In this application, to determine the installable area for buttons in the trunk, the body model parameters of the human model are adjusted according to the button type to obtain multiple first model information. Combining this first model information with the structural information of the vehicle trunk, the comfortable operating area corresponding to the button of that operation type when installed in the vehicle trunk is determined, thus providing a reference for the subsequent design of button positions in the vehicle trunk.

[0083] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0084] Figure 1 A flowchart illustrating a method for determining a trunk operating comfort zone provided in this application embodiment is shown below. Figure 1 As shown, the method includes the following steps:

[0085] S101. Obtain the structural information of the vehicle's trunk and the standard model information of the human body model; wherein, the structural information is used to indicate the position information of each structure in the trunk; and the standard model information is used to indicate the body model parameters of the human body model.

[0086] For example, the structural information of the trunk in this application is used to characterize the positional information of the corresponding structure inside the vehicle trunk, that is, to characterize the internal structure of the vehicle trunk. Furthermore, the human body model is a simulation model constructed based on the human body, and the body model parameters of the human body model are specifically used to characterize the body model parameters. It should be noted that in this embodiment, standard model information for one human body model can be obtained, or standard model information corresponding to multiple human body models can be obtained. This embodiment does not impose a specific limit on the number of human body models obtained. For example, standard model information corresponding to at least one male human body model and at least one female human body model can be obtained, so that the comfort zone for button operation can be determined subsequently.

[0087] S102. Based on the operation type of the button to be tested on the vehicle's trunk, adjust the body model parameters in the standard model information to obtain multiple first model information; wherein, the first model information is used to indicate the adjusted body model parameters.

[0088] For example, in this embodiment, the hand shape and the shape of the rest of the body of the user when controlling the button will be different for different operation types of buttons. Therefore, in this embodiment, in order to ensure the accuracy of the operation comfort zone determination, the body model parameters in the obtained standard model information will be adjusted according to the operation type of the button to be tested set in the vehicle trunk, so as to obtain multiple first model information.

[0089] It should be noted that in this embodiment, during the adjustment of the standard model information, in addition to adjusting the hand model parameters in the model parameter information so that the adjusted hand model parameters are suitable for the operation type corresponding to the button under test, it is also necessary to consider the adjustment of other body parts in the body model parameters. For example, adjusting the distance between the feet when standing, the shape parameters of the arms, and the shape parameters of the back, etc., in order to obtain multiple different first model information. It should also be noted that in the process of adjusting the body model parameters of the above-mentioned human body model, human comfort needs to be considered. That is, the body model parameters corresponding to the first model information obtained after adjustment are the parameters corresponding to the human body in a comfortable state, so as to simulate the real comfortable posture of a real user when performing button control operation.

[0090] S103. Based on the first model information and the trunk structure information, determine the operating comfort zone of the button to be tested; wherein, the operating comfort zone is the installable area of ​​the button to be tested on the trunk of the vehicle.

[0091] For example, in this embodiment, after obtaining multiple first model information, the final operating comfort zone of the button to be tested can be simulated by combining the multiple first model information and the structural information of the trunk.

[0092] Specifically, by combining the first model information and the structural information of the vehicle trunk, the accessible position information in the vehicle trunk corresponding to the body model parameters represented by the first model information can be determined. Then, based on the accessible position information corresponding to each of the multiple first model information, the final operating comfort zone can be determined. For example, the aforementioned accessible position information can be used as the farthest position of the human hand that can be touched under the first model information. Then, the surface obtained by fitting multiple position information is used as the farthest surface that the user can touch in a comfortable state, thereby dividing the operating comfort zone corresponding to the trunk.

[0093] In one example, when there are multiple human models determined in step S101, the corresponding operating comfort zone for each human model can be determined through steps S102 and S103. Then, the intersection of the multiple operating comfort zones can be used as the final determined operating comfort zone of the button to be tested, so that the final operating comfort zone is applicable to users of various body types.

[0094] It is understood that in this embodiment, the body model parameters in the standard model information are adjusted by combining the operation type of the buttons in the vehicle trunk, so that the user posture represented by the adjusted first model information is a posture suitable for operating the aforementioned button operation type. Furthermore, the operation comfort zone finally fitted in this embodiment is applicable to multiple buttons under this operation type, eliminating the need for different operation comfort zone detections for each button. This ensures that the final operation comfort zone is applicable not only to the button under test but also to other buttons under this operation type, thereby providing a reference for button design and improving the convenience and comfort of button operation in the trunk.

[0095] Figure 2 A flowchart illustrating another method for determining the trunk operating comfort zone provided in this application embodiment is shown below. Figure 2 As shown, the method includes the following steps:

[0096] S201. Obtain the structural information of the vehicle's trunk and the standard model information of the human body model; wherein, the structural information is used to indicate the position information of each structure in the trunk; and the standard model information is used to indicate the body model parameters of the human body model.

[0097] In one example, the body model parameters include: a first angle, a second angle, and hand shape parameters; wherein, the first angle represents the curvature of the waist; the second angle represents the angle between the arm and the torso; and the hand shape parameters represent the shape of the human body model's hand.

[0098] For example, in this embodiment, the body model parameters in the standard model information may include hand shape parameters, which are parameters characterizing the hand shape in the human body model. Furthermore, the first angle in the body model parameters represents the degree of curvature of the waist in the human body model, and the second angle in the body model parameters represents the angle between the arm and torso in the human body model. When subsequently adjusting the standard model information of the human body model, the above-mentioned parameters in the body model parameters can be adjusted to simulate a real user's button operation in the trunk, thereby determining the final comfortable operating zone corresponding to the button.

[0099] In one example, the structural information of the vehicle's trunk and the vehicle's sales range information are obtained; wherein, the sales range information represents at least one of the vehicle's corresponding sales region and target sales object; based on the sales range information, the standard model information of the human body model is determined.

[0100] For example, in this embodiment, when obtaining the standard model information of the human body model, the sales range information of the vehicle can be combined to select the human body model that matches the current vehicle from multiple human body models.

[0101] The vehicle sales scope can include the sales region corresponding to the vehicle. It is understandable that there will be some differences in the average overall body size across different regions. Therefore, when obtaining standard human body model information, the appropriate standard human body model information can be selected based on the vehicle's sales region.

[0102] Furthermore, the vehicle's sales scope information can also include information that characterizes the target sales audience for the subsequent vehicle, i.e., the primary user group the vehicle is intended for. For example, it could be primarily targeted at different groups such as the elderly, men, or women. Based on the target sales audience, the model parameters of the final selected anthropomorphic model are determined.

[0103] It is understandable that in this embodiment, the human body model that matches the current vehicle is selected by combining the sales range information corresponding to the vehicle, so as to improve the comfort of subsequent users operating the buttons in the trunk.

[0104] It should be noted that in practical applications, there is a difference between the structural information of the vehicle's trunk and the vehicle's load, i.e., the structural information corresponding to different loads. For example, the distance between the platform on which the vehicle's trunk is located and the ground reference plane corresponding to the vehicle when the vehicle is empty is greater than the distance when the vehicle is fully loaded. When obtaining the structural information of the vehicle's trunk, it can also be determined in conjunction with the application scenario of the button. For example, if the button to be tested can only be controlled under certain load conditions in the vehicle, the structural information corresponding to the corresponding load can be selected to determine the subsequent operating comfort zone. If the control trigger of the button to be tested is unrelated to the vehicle's load, the structural information corresponding to the vehicle's empty state can be selected to determine the operating comfort zone. Therefore, the above-mentioned method of obtaining structural information helps to improve the accuracy of subsequent operating comfort zone determination.

[0105] S202. If the operation type of the button to be tested is determined to be stretching, the hand shape parameter in the standard model information is adjusted to the first shape parameter to obtain the second model information; wherein, the first shape parameter is the shape parameter of the index finger of the human body model in a bent state; the second model information includes: the first shape parameter, the first included angle in the standard model information, and the second included angle in the standard model information.

[0106] For example, in this embodiment, when it is determined that the operation type of the button to be tested is a stretching type, the hand shape parameters in the standard model information can be adjusted according to the hand change shape corresponding to the user controlling the stretching type button. In this embodiment, when adjusting the hand shape parameters, the index finger of the hand in the human body model is controlled to be in a bent state, that is, the hand shape parameters are adjusted to the first shape parameters, so that the operating comfort zone can be determined according to the area that can be reached after the index finger is bent.

[0107] S203. Adjust the first angle and the second angle in the second model information to obtain multiple first model information, wherein the first model information is used to indicate the adjusted body model parameters.

[0108] For example, after adjusting the hand shape parameters in the standard model information to the first shape parameters, the first included angle and the second included angle in the obtained second model information are further adjusted.

[0109] For example, in practical applications, multiple comfortable waist bending angles (i.e., the corresponding values ​​of the first included angle) and multiple comfortable angle values ​​between the arms and torso (i.e., the values ​​of the second included angle) can be randomly selected. The values ​​of the first included angle and the second included angle are then randomly combined and used as the values ​​of the first included angle and the second included angle in the adjusted first model information.

[0110] It is understood that, in this embodiment, specifically for the control button of the stretching operation type, the second model information can be obtained by first adjusting the hand shape parameter to the first shape parameter, and then by traversing the values ​​of the first and second included angles in multiple combinations to obtain multiple sets of first model information, so as to accurately determine the installable area of ​​the button of the stretching operation type in the trunk of the vehicle.

[0111] In one example, step S203 can be achieved through the following steps: determining a first set of values ​​corresponding to the first included angle; wherein the first set of values ​​includes multiple different first values; determining a second set of values ​​corresponding to the second included angle under the first value; wherein the second set of values ​​includes multiple different second values; the maximum values ​​in the first and second set of values ​​are negatively correlated; the maximum value is the largest value among the second values ​​contained in the second set of values; and obtaining multiple sets of first model information based on the second model information, the first set of values, and the second set of values.

[0112] For example, in this embodiment, when adjusting the first angle and the second angle in the second model parameters, a first set of values ​​corresponding to the first angle is first determined. Furthermore, each first value in the first set of values ​​corresponds to its own second set of values. The second set of values ​​includes the range of values ​​for the second angle corresponding to the first angle at that first value. It should be noted that in this embodiment, the value corresponding to the first angle is a possible value for the degree of lumbar flexion when the human body is in a bent-over state, and in a comfortable bent-over state. It should also be noted that in this embodiment, the first angle specifically refers to the angle between the torso in an upright state and when the torso is in a bent-over state. Furthermore, in this embodiment, the second value corresponding to the second angle is different under different first values. Specifically, it can be understood that as the curvature of the human waist increases, that is, as the value of the first angle increases, the range of human vision moves downward. At this time, from the perspective of operational comfort, the maximum value of the angle between the line where the arm is located and the line where the human torso is located (i.e., the second angle) also decreases. That is, the maximum value in the first and second value sets of the first angle is negatively correlated.

[0113] Furthermore, by setting the first set of values ​​and the second set of values ​​corresponding to each first value in the first set of values, the comfort of human operation is fully considered, thereby avoiding the problem of inaccurate determination of the operating comfort zone when the second set of values ​​corresponding to each first value is exactly the same.

[0114] S204. If the operation type of the button to be tested is determined to be a press type, then adjust the hand shape parameter in the standard model information to the second shape parameter to obtain the third model information; wherein, the second shape parameter is the shape parameter of the index finger of the hand in a straight state; wherein, the first shape parameter is the shape parameter of the index finger of the human body model in a bent state; the second model information includes: the second shape parameter, the first included angle in the standard model information, and the second included angle in the standard model information.

[0115] For example, after step S201, when it is determined that the operation type of the button to be tested in the vehicle's trunk is a press type, since press type buttons are usually triggered by a human finger in a straight state, the hand shape parameters in the standard model information can be adjusted to the shape parameters of the index finger in a straight state, thereby obtaining the adjusted third model information. It should be noted that in this embodiment, only the hand shape parameters in the standard model information are adjusted; the remaining information contained in the third model information is still retained as the corresponding parameters in the standard model information.

[0116] S205. Adjust the first and second included angles in the third model information to obtain multiple first model information.

[0117] For example, the specific principle of step S205 can be found in step S203, and will not be repeated here.

[0118] It is understandable that in this embodiment, for press-type operation buttons, the hand shape parameters in the standard model information are adjusted to the parameters of the index finger in a straight state to simulate the control of press-type operation buttons in real scenarios, so that the button operation comfort zone can be determined based on the position of the index finger under different first and second angles.

[0119] S206. If the operation type of the button to be tested is determined to be rotation type, adjust the hand shape parameter in the standard model information to the third shape parameter to obtain the fourth model information; wherein, the third shape parameter is the shape parameter of the index finger and thumb in a bent state; the fourth model information includes: the third shape parameter, the first included angle in the standard model information, and the second included angle in the standard model information.

[0120] For example, in this embodiment, after step S201, for the rotation type button to be tested, the hand shape parameters in the standard model information are adjusted at the same time to adjust the bending state between the index finger and thumb, so as to use the hand shape indicated by the third shape parameter to simulate the real hand shape corresponding to the user operating the rotation type button.

[0121] S207. Adjust the first and second included angles in the fourth model information to obtain multiple first model information.

[0122] For example, the specific principle of step S207 can be found in step S203, and will not be repeated here.

[0123] S208. Under the preset coordinate system, control the structural information of the trunk and the information of the first model to be located on the same ground reference plane; and control the distance between the leg parameters in the first model information and the rear cover parameters in the structural information of the trunk to be less than a preset value.

[0124] For example, in this embodiment, the acquired structural information and the first model information are set in the same preset coordinate system. Furthermore, to further determine the operating comfort zone corresponding to the buttons in the trunk, the trunk model indicated by the trunk's structural information and the human body model indicated by the first model information are set on the same ground reference plane. That is, the plane corresponding to the lowest point of the vehicle's wheels in the trunk's structural information and the human body standing plane represented in the first model information are set on the same plane. Then, the human body model indicated by the first model information needs to be moved to the trunk model indicated by the vehicle's trunk's structural information. That is, the distance between the leg parameters in the first model information and the rear cover parameters in the trunk's structural information needs to be less than a preset value so that the legs of the human body model fit snugly against the trunk's rear cover. It should be noted that the leg parameters in this embodiment can be parameters corresponding to any one or more points of the human leg portion represented by the first model information. Similarly, the rear cover parameters of the trunk are parameters corresponding to one or more points of the rear cover portion of the vehicle's trunk.

[0125] S209. Determine the position information of the hand corresponding to the first model information.

[0126] For example, after adjusting the relative positions between the first model information and the structural information in step S208, the position information of the hand corresponding to the first model information can be further determined. It should be noted that the position information of the hand here can be the specific coordinate values ​​of the hand morphology parameters represented by the first model information in a preset coordinate system. For instance, when the first model information includes a first hand morphology parameter, the position information of the bending point of the index finger in the preset coordinate system can be determined as the hand position information.

[0127] S210. Based on the hand position information corresponding to each first model information, a touchable surface is obtained by fitting.

[0128] For example, after determining the hand position information corresponding to each of the first model information, a surface can be obtained by fitting multiple position information, and this surface can be used as the farthest surface that the human body can reach within a comfortable range. It should be noted that the method of fitting a surface from multiple points can refer to the fitting methods in related technologies, and no specific limitation is made in this embodiment.

[0129] In one example, the position information of the hand is grouped according to the first included angle in each first model information to obtain at least one group set; wherein, the group set includes the position information of at least one hand, and the first included angle of the first model information corresponding to the position information of the hand in the same group set is the same; the first included angle represents the waist curvature; the fitting curve corresponding to the group set is determined; wherein, the fitting curve is obtained by fitting the position information of the hand contained in the group set; the touchable surface is determined according to the fitting curve.

[0130] For example, in this embodiment, when fitting the tactile surface, the obtained position information of multiple hands can first be grouped. That is, the hand position information corresponding to the first model information with the same first included angle is divided into the same group, and the fitting curve corresponding to each group is fitted according to the position information contained in each group. That is, for each waist curvature, a fitting curve is determined to characterize the position that the human hand can touch at that curvature angle. Then, the final tactile surface is obtained by further fitting the multiple fitting curves.

[0131] It is understood that in this embodiment, the method of first fitting the fitting curves at each waist bending angle to determine the tangible surface is adopted so that when it is necessary to add the values ​​of the first or second included angle for fitting later, the original fitting curve can be retained or updated, thereby improving the fitting efficiency of the tangible surface.

[0132] S211. Based on the tactile curved surface and the structural information of the trunk, determine the operating comfort zone of the button to be tested; wherein, the operating comfort zone is the installable area of ​​the button to be tested on the trunk of the vehicle.

[0133] For example, after the tactile surface is fitted, the tactile surface is used as the farthest surface, and based on the farthest surface, the trunk area represented in the structural information of the trunk is divided to obtain the operating comfort zone of the button to be tested.

[0134] It is understood that in this embodiment, after unifying the first model information and structural information under the same preset coordinate system, the relative position between the first model information and structural information is set to simulate the real scenario of a human body close to the trunk to perform corresponding control operations in a real environment, so as to accurately determine the operating comfort zone of the button to be tested.
