[0038] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0039] Embodiment 1

[0040] The first embodiment of the present invention provides a universal design method for a vehicle cockpit, such as Figure 1 As shown, including:

[0041] S101, obtaining multiple groups of cockpit parameters of a vehicle cockpit, wherein each group of cockpit parameters includes a vehicle width parameter and a heel point height value, wherein the heel point height value is a height distance between a heel point of the vehicle driver and a point R in the cockpit;

[0042] S102, obtaining a plurality of design data of each of a plurality of components of the cockpit according to the plurality of groups of cockpit parameters, wherein the plurality of components include at least one of an accelerator pedal, a brake pedal, a door sill beam, and a steering wheel of the cockpit;

[0043] S103, determining the position data of each component according to the multiple design data of each component.

[0044] The universal vehicle cockpit design method of this embodiment is applied to terminal devices, such as personal computers, laptops or tablet computers, and is also specifically applied to the vehicle model design stage.

[0045] Next, combine Figure 1 The specific implementation steps of the universal design method for the vehicle cockpit provided by this embodiment are described in detail:

[0046] First, execute step S101 to obtain multiple groups of cockpit parameters of the vehicle cockpit, wherein each group of cockpit parameters includes a vehicle width parameter and a heel point height value, and the heel point height value is the height distance between the heel point of the vehicle driver and point R in the cockpit.

[0047] Specifically, first obtain multiple sets of cockpit parameters of the vehicle cockpit, each set of cockpit parameters in the multiple sets of cockpit parameters includes but is not limited to a vehicle width parameter, an R point ordinate value, and a heel point height value, the R point ordinate value is the ordinate value W20 of the R point of the vehicle in the vehicle coordinate system, and the heel point height value is the height distance between the heel point of the vehicle driver and the R point. Figure 2 As shown, point R and heel point are in the cockpit and both are on the bottom plane of the vehicle, and the heel point height value refers to the height distance H30 between the heel point and point R.

[0048] It also needs to be explained that a set of cockpit parameters represents a vehicle model.

[0049] Next, step S102 is executed to obtain multiple design data of each of the multiple components of the cockpit based on the multiple groups of cockpit parameters, wherein the multiple components include at least one of an accelerator pedal, a brake pedal, a door sill beam and a steering wheel of the cockpit.

[0050] Specifically, the process of obtaining multiple design data of each component is to obtain each design data of each component according to each set of cockpit parameters; after obtaining each design data of each component, multiple design data of each component are obtained. Taking the accelerator pedal and the brake pedal as an example, after obtaining N sets of cockpit parameters of the cockpit, one design data of the accelerator pedal is obtained according to each set of cockpit parameters, and one design data of the brake pedal is also obtained, wherein N is an integer greater than 1. Therefore, according to the N sets of cockpit parameters, N design data of the accelerator pedal are obtained, and N design data of the brake accelerator pedal are also obtained.

[0051] Since the multiple components include at least one of the accelerator pedal, brake pedal, sill beam and steering wheel of the cockpit, the preferred solution is that the multiple components include the accelerator pedal, brake pedal, sill beam and steering wheel of the cockpit. Taking the preferred solution as an example, the process of obtaining a design data of each component according to each set of cockpit parameters is explained.

[0052] The process of obtaining the design data of the accelerator pedal is to obtain the longitudinal distance Y1 between the accelerator pedal point and the R point according to the specified angle of the accelerator pedal point and the specified distance of the accelerator pedal point in each set of cockpit parameters.

[0053] The specified angle of the accelerator pedal point is the angle between the line between the projection point of the accelerator pedal point and the projection point of point R in the bottom plane of the vehicle and the straight line passing through point R and extending in the negative horizontal axis direction of the vehicle coordinate system. The specified distance of the accelerator pedal point is the distance between the projection point of the accelerator pedal point and the projection point of point R in the bottom plane of the vehicle. The longitudinal distance between the accelerator pedal point and point R is the distance between the accelerator pedal point and point R on the longitudinal axis of the vehicle coordinate system, and each design data of the accelerator pedal includes the longitudinal distance between the accelerator pedal point and point R.

[0054] Specifically, Figure 3 As shown, Figure 3 This is a top view from the roof to the bottom of the vehicle. Figure 3 middle, Figure 3 The R' point in the figure is the projection point of the R point in the cockpit onto the plane of the bottom of the vehicle, and the P1' point is the projection point of the accelerator pedal point P1 onto the plane of the bottom of the vehicle. The specified angle α of the accelerator pedal point is the angle between the line connecting the P1' point and the R' point and the straight line extending through the R point in the direction of the negative horizontal axis (-X axis) of the vehicle coordinate system, wherein the straight line extending through the R point in the direction of the negative horizontal axis (-X axis) of the vehicle coordinate system is also the straight line extending through the R' point in the direction of the negative horizontal axis (-X axis) of the vehicle coordinate system. The specified distance of the accelerator pedal point is the distance between the P1' point and the R' point, which is L1. The longitudinal distance Y1 between the accelerator pedal point and the R point is L1×sinα.

[0055] The process of obtaining the design data of the brake pedal is to obtain the longitudinal distance Y2 between the brake pedal point and the R point based on the specified angle of the brake pedal point and the specified distance of the accelerator pedal point in each set of cockpit parameters.

[0056] Among them, the specified angle of the brake pedal point is the angle between the line connecting the projection point of the brake pedal point and the projection point of point R in the bottom plane of the vehicle and the straight line passing through point R and extending in the negative horizontal axis direction of the vehicle coordinate system, the longitudinal distance between the brake pedal point and point R is the distance between the brake pedal point and point R on the longitudinal axis of the vehicle coordinate system, and each design data of the brake pedal includes the longitudinal distance between the brake pedal point and point R.

[0057] Specifically, Figure 4 As shown, Figure 4 This is a top view from the roof to the bottom of the vehicle. Figure 4 middle, Figure 4The R' point is the projection point of the R point in the cockpit onto the bottom plane of the vehicle, and the P2' point is the projection point of the brake pedal point P2 onto the bottom plane of the vehicle. The specified angle β of the brake pedal point is the angle between the line connecting the P2' point and the R' point and the straight line passing through the R point and extending in the direction of the negative horizontal axis (-X axis) of the vehicle coordinate system. The longitudinal distance Y2 between the brake pedal point and the R point is (L1-C)×sinβ, where C is the relationship constant between the accelerator pedal point and the brake pedal point. The specific value of C is set according to actual needs, and C is usually set to 30.

[0058] The process of obtaining the design data of the threshold beam is to obtain the longitudinal distance Y3 between the stop of the threshold beam and the point R according to the vehicle width parameter in each set of cockpit parameters. Each design data of the threshold beam includes the longitudinal distance between the stop of the threshold beam and the point R, and the longitudinal distance Y3 between the stop of the threshold beam and the point R is the distance between the stop of the threshold beam and the point R on the longitudinal axis of the vehicle coordinate system.

[0059] Specifically, the longitudinal distance between the stop of the sill beam and the point R is Y3=W / 2-150, wherein W is a vehicle width parameter and 150 is a constant value, which can be set according to actual needs.

[0060] The process of obtaining the design data of the steering wheel is to obtain the lateral distance X1 and the vertical distance Z1 between the center point of the steering wheel and the point R according to the heel point height value in each set of cockpit parameters, and measure the longitudinal distance Y4 between the center point of the steering wheel and the point R. Wherein, each design data of the steering wheel includes the lateral distance, longitudinal distance and vertical distance between the center point of the steering wheel and the point R, the lateral distance between the center point of the steering wheel and the point R is the distance between the center point of the steering wheel and the point R on the horizontal axis (X axis) of the vehicle coordinate system, the vertical distance between the center point of the steering wheel and the point R is the distance between the center point of the steering wheel and the point R on the vertical axis (Z axis) of the vehicle coordinate system, and the longitudinal distance between the center point of the steering wheel and the point R is the distance between the center point of the steering wheel and the point R on the vertical axis (Y axis) of the vehicle coordinate system.

[0061] Specifically, the lateral distance X1 between the center point of the steering wheel and the point R is: X1 = 0.0028 (H30) 2 - 1.5528 (H30) + 627, where H30 is the heel height value. The vertical distance Z1 between the center point of the steering wheel and the point R is: Z1 = -0.0009 (H30) 2 + 0.2451 (H30) + 391. The longitudinal distance Y4 between the center point of the steering wheel and the point R is directly measured, and preferably the center point of the steering wheel is aligned with the point R, that is, the ordinate value of the center point of the steering wheel in the vehicle coordinate system is consistent with the ordinate value YR of the point R in the vehicle coordinate system.

[0062] It should be noted that the units of parameters such as distance and height involved in this embodiment are all millimeters.

[0063] Then, step S103 is executed to determine the position data of each component according to the multiple design data of each component.

[0064] Specifically, for each component, if multiple design data of the component are all within a set threshold range of the component, the mean or median of the multiple design data of the component is used as the position data of each component.

[0065] In the specific implementation process, the setting threshold range of each component is different, and the setting threshold range of each component can be set according to actual needs. Usually, the setting threshold range of the accelerator pedal is 175mm±15mm, the setting threshold range of the brake pedal is 90mm±10mm, the setting threshold range of the threshold beam is set to (Y3-W20)-W20 result Y5 is located in [0, 15], and the setting threshold range of the vertical coordinate of the steering wheel in the vehicle coordinate system is YR±5mm.

[0066] Taking the accelerator pedal as an example, if 5 sets of cockpit parameters are obtained, a design data of the accelerator pedal is obtained according to each set of cockpit parameters. Then, according to the 5 sets of cockpit parameters, 5 design data of the accelerator pedal are obtained. If these 5 design data are all within the set threshold range of 175mm±15mm of the accelerator pedal, it means that these 5 vehicle models can share the same set of accelerator pedals, then the average value or median or the result value of other algorithms or one of them is taken for these 5 design data, and the average value or median or the result value of other algorithms or one of them is taken as the final position data of the accelerator pedal.

[0067] For each component, if only one of the multiple design data of the component is not within the set threshold range of the component, the first position data of the component is obtained based on the design data, and the second position data of the component is obtained based on the design data other than the design data in the multiple design data.

[0068] Taking the accelerator pedal as an example, if 5 sets of cockpit parameters are obtained, a design data of the accelerator pedal is obtained according to each set of cockpit parameters. Then, according to the 5 sets of cockpit parameters, 5 design data of the accelerator pedal are obtained, which are recorded as M1, M2, M3, M4 and M5 respectively. If only one design data (M2) among the 5 design data is not within the set threshold range of 175mm±15mm of the accelerator pedal, and the remaining 4 design data (M1, M3, M4 and M5) are all within the set threshold range of the accelerator pedal, it means that the vehicle model corresponding to M1, the vehicle model corresponding to M3, the vehicle model corresponding to M4 and the vehicle model corresponding to M5 can share the same set of accelerator pedals, and the vehicle model corresponding to M2 uses a separate set of accelerator pedals. Then, according to M2, the first position data of the accelerator pedal is obtained, and the first position data is M2, and the average value or median value or other algorithm is calculated by M1, M3, M4 and M5 to obtain the result value of the average value or median value or other algorithm, and then the average value or median value or other algorithm result value or one of them is selected as the second position data of the accelerator pedal.

[0069] For each component, if at least two of the multiple design data of the component are not within the set threshold range of the component, then according to the set clustering range of the component, the multiple design data of the component are clustered and analyzed to obtain multiple clustering results of the component, and according to each clustering result, a position data of the component is obtained, and after obtaining the position data of the component, multiple position data of the component are obtained. The clustering range is set according to actual needs, and the clustering algorithm for implementing the clustering analysis can also be set according to actual needs.

[0070] Taking the accelerator pedal as an example, if 5 sets of cockpit parameters are obtained, a design data of the accelerator pedal is obtained according to each set of cockpit parameters. Then, according to the 5 sets of cockpit parameters, 5 design data of the accelerator pedal are obtained, which are recorded as M1, M2, M3, M4 and M5 respectively. If 2 of the 5 design data (M2, M3) are not within the set threshold range of 175mm±15mm of the accelerator pedal, and the remaining 3 design data (M1, M4 and M5) are all within the set threshold range of the accelerator pedal, it means that the vehicle model corresponding to M1, the vehicle model corresponding to M4 and the vehicle model corresponding to M5 can share the same set of accelerator pedals, while the vehicle model corresponding to M2 and the vehicle model corresponding to M3 may each use a set of accelerator pedals separately, or the vehicle model corresponding to M2 and the vehicle model corresponding to M3 share a set of accelerator pedals. Then, according to the set threshold range, M1, M4 and M5 are clustered into one category, and according to M1, M4 and M5, a position data of the accelerator pedal is obtained. According to the set clustering range of the accelerator pedal, M2 and M3 are clustered. If M2 and M3 are grouped together, a position data of the accelerator pedal is obtained according to M2 and M3. If M2 and M3 are not grouped together, a position data of the accelerator pedal is obtained according to M2 (i.e., M2), and a position data of the accelerator pedal is obtained according to M3 (i.e., M3).

[0071] Alternatively, if two of the five design data (M2, M3) are not within the set threshold range of 175 mm ± 15 mm for the accelerator pedal, and the remaining three design data (M1, M4, and M5) are all within the set threshold range of the accelerator pedal, then cluster analysis is performed on M1-M5 according to the set cluster range of the accelerator pedal. The clustering result is that M1 and M5 are one group, and M2, M3, and M4 are one group. Based on M1 and M5, a position data of the accelerator pedal is obtained. Based on M2, M3, and M4, a position data of the accelerator pedal is obtained.

[0072] In addition, this embodiment further introduces in detail an implementation method for determining the position data of each component according to the multiple design data of each component:

[0073] Taking the accelerator pedal as an example, three sets of cockpit parameters are obtained, and the design data of three accelerator pedals are obtained, which are recorded as Q1, Q2 and Q3 respectively.

[0074] If Q1, Q2 and Q3 are all within the set threshold range of 175mm±15mm of the accelerator pedal, indicating that the vehicle model corresponding to Q1, the vehicle model corresponding to Q2 and the vehicle model corresponding to Q3 can share a set of accelerator pedals, then the average value or median value or other algorithm result value of Q1, Q2 and Q3 is taken, and the obtained average value or median value or other algorithm result value is used as the final position data of the accelerator pedal.

[0075] If only Q1 among Q1, Q2 and Q3 is not within the set threshold range of 175mm±15mm of the accelerator pedal, it means that the vehicle type corresponding to Q1 uses the accelerator pedal with the position data of Q1 alone, and the vehicle type corresponding to Q2 and the vehicle type corresponding to Q3 can share a set of accelerator pedals, then Q1 is used as the first position data of the accelerator pedal, and the average value or median value or the result value of other algorithms of Q2 and Q3 are taken, and the obtained average value or median value or the result value of other algorithms are taken as the second position data of the accelerator pedal.

[0076] If Q1 and Q2 among Q1, Q2 and Q3 are not located within the set threshold range of 175mm±15mm of the accelerator pedal, then Q1, Q2 and Q3 are clustered according to the set clustering range of the accelerator pedal to obtain multiple clustering results, and based on each clustering result, a position data of the accelerator pedal is obtained, and then multiple position data of the accelerator pedal are obtained.

[0077] The process of obtaining multiple position data of the accelerator pedal is to assume that Q1 is the maximum value among Q1, Q2 and Q3, and Q2 is the minimum value among Q1, Q2 and Q3. Q1 and Q2 are subtracted to obtain the difference Q', that is, Q' = Q1-Q2. Q1, Q2 and Q3 are also subjected to tolerance calculation to obtain the tolerance number G, and the tolerance number G of the accelerator pedal = 15mm.

[0078] If Q'>6 times the tolerance number (6G), that is, Q'>6×15=90, it means that the vehicle model corresponding to Q1, the vehicle model corresponding to Q2 and the vehicle model corresponding to Q3 cannot share a set of accelerator pedals, then the vehicle model corresponding to Q1 uses the accelerator pedal with position data of Q1 alone, the vehicle model corresponding to Q2 uses the accelerator pedal with position data of Q2 alone, and the vehicle model corresponding to Q3 uses the accelerator pedal with position data of Q3 alone.

[0079] If 4G=60≥Q'≥90, then obtain the difference Q4 between Q1 and Q2, the difference Q5 between Q1 and Q3, and the difference Q6 between Q2 and Q3. Among Q4, Q5 and Q6, whichever value is within the range of 2 times the tolerance (2G=30), then obtain the position data of the accelerator pedal according to the design data corresponding to the value. If Q4 is located in [0, 30], it means that the vehicle model corresponding to Q1 and the vehicle model corresponding to Q2 can share a set of accelerator pedals, and the vehicle model corresponding to Q3 uses the accelerator pedal with position data Q3 alone. Then, according to Q1 and Q2, obtain one position data of the accelerator pedal, and according to Q3, obtain another position data of the accelerator pedal.

[0080] One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0081] In this embodiment, a plurality of sets of cockpit parameters of the vehicle cockpit are first obtained, wherein each set of cockpit parameters includes a vehicle width parameter and a heel point height value, wherein the heel point height value is the height distance between the heel point of the vehicle driver and the R point in the cockpit. Then, according to the plurality of sets of cockpit parameters, a plurality of design data of each of the plurality of components of the cockpit are obtained, wherein the plurality of components include at least one of an accelerator pedal, a brake pedal, a sill beam and a steering wheel of the cockpit. Then, according to the plurality of design data of each component, the position data of each component is determined, so as to realize unified calculation and unified planning of the accelerator pedal, brake pedal, steering wheel position and sill width in the cockpit of all vehicle models in the early stage of vehicle development, avoid changes in vehicle design in the later stage, improve the efficiency of cockpit design, reduce the types of components, reduce the scope of changes, reduce the difficulty of workshop process, shorten the development cycle, save development costs, and improve the installation accuracy of the vehicle.
