[0069] Embodiment 1

[0070] Figure 1 is a flowchart of a method for checking an automotive instrument panel cover based on the CATIA tool proposed in an embodiment of the present invention. As Figure 1 shown, the method includes:

[0071] S101, in response to a user's operation instruction for establishing elements, display the instrument screen surface, the inner surface of the instrument cover, the left eye ellipse, and / or the right eye ellipse;

[0072] It should be noted that there are various elements in the CATIA tool. The user can establish the corresponding display instrument screen surface and the inner surface of the instrument cover according to actual needs (such as according to design requirements, vehicle model requirements, etc.). In addition, in order to simulate the driver's line of sight, the left eye ellipse and / or the right eye ellipse are used to represent the driver's left eye and right eye. In the above steps, only the left eye ellipse can be established, or only the right eye ellipse can be established, or both the left eye ellipse and the right eye ellipse can be established simultaneously. For the simplicity of the steps, in the following embodiments, only the establishment of the left eye ellipse is taken as an example for illustration, where the left eye ellipse is the upper part of the 95% left eye ellipse.

[0073] S102, in response to a user's operation instruction for finding the reflected rays of the line of sight of the left eye ellipse and the right eye ellipse to the instrument screen surface, display the reflected rays;

[0074] It can be understood that after establishing the left eye ellipse, a tangent line of the left eye ellipse can be made starting from a point on the instrument screen surface. The tangent line of the left eye ellipse is used to represent the line of sight of the left eye ellipse to the instrument screen surface. Finally, the reflected ray of this line of sight on the instrument screen surface is found. Then, according to whether the intersection point of this reflected ray and the inner surface of the instrument cover is within the inner surface of the instrument cover, it is checked whether the inner surface of the instrument cover can block the reflection of surrounding objects.

[0075] S103, in response to a user's shear operation instruction, cause the inner surface of the instrument cover to shear the reflected rays to form reflected line segments;

[0076] That is to say, select the inner surface of the instrument cover and all the reflected rays, and use the shear operation instruction to retain the reflected line segments between the inner surface of the instrument cover and the instrument screen surface.

[0077] S104, in response to a user's first intersection operation instruction, obtain the entry points of the reflected line segments on the inner surface of the instrument cover;

[0078] That is to say, after obtaining the reflected line segments, the entry points of the reflected line segments on the inner surface of the instrument cover can be obtained in response to the first intersection operation instruction;

[0079] S105, according to the positions of the entry points, judge whether the inner surface of the instrument cover can block the reflection of surrounding objects to check the instrument cover.

[0080] Among them, when all the entry points are on the inner surface of the instrument cover, the inner surface of the instrument cover can block the reflection of surrounding objects. Otherwise, the inner surface of the instrument cover cannot block the reflection of surrounding objects.

[0081] That is to say, if the inner surface of the instrument cover can block the reflections of surrounding objects, then all the reflected light rays of the light entering the driver's eyes should be located within the inner surface of the instrument cover. If the inner surface of the instrument cover cannot block the reflections of surrounding objects, then some of the reflected light rays of the light entering the driver's eyes are located within the inner surface of the instrument cover, and some are located outside the inner surface of the instrument cover. At this time, it indicates that the driver's line of sight is affected and the parameters of the instrument cover need to be corrected in design.

[0082] Thus, through the CATIA tool, it is possible to check whether the instrument cover can effectively block the reflected light rays of surrounding objects, thereby avoiding the reflected light rays of surrounding objects from affecting the driver's line of sight. This method has strong visibility, simple steps, and high checking efficiency.

[0083] Since the left-eye ellipse established is an ellipsoid, there is no direct command in the CATIA tool to draw a tangent line from a point on the instrument screen surface to the ellipsoid. Thus, the following takes a specific embodiment to introduce how the line of sight entering the driver's eyes is obtained through the CATIA tool.

[0084] According to an embodiment of the present invention, the method step in S101 further includes:

[0085] In response to the user's operation instruction for establishing an element, a symmetry plane is displayed, wherein the left-eye ellipse and the right-eye ellipse are symmetric with respect to the symmetry plane;

[0086] As Figure 2 shown, step S102 includes:

[0087] S1021, in response to the user's second intersection operation instruction, display the first intersection line of the outer contour line of the left-eye ellipse and / or the outer contour line of the right-eye ellipse with a plane parallel to the symmetry plane;

[0088] Optionally, the plane parallel to the symmetry plane can be the central plane of the left-eye ellipse or the central plane of the right-eye ellipse.

[0089] Wherein, the first intersection line can be the intersection line of the outer contour line of the left-eye ellipse and the central plane of the left-eye ellipse, or the intersection line of the outer contour line of the right-eye ellipse and the central plane of the right-eye ellipse. The following takes the left-eye ellipse as an example for illustration, and the right-eye ellipse example refers to the left-eye ellipse example.

[0090] In the above embodiment, the central plane of the left-eye ellipse is obtained through the following steps: in response to the user's left translation operation instruction, translate the symmetry plane to the left by a first preset distance to obtain the central plane of the left-eye ellipse; the central plane of the right-eye ellipse is obtained through the following steps: in response to the user's right translation operation instruction, translate the symmetry plane to the right by a first preset distance to obtain the central plane of the right-eye ellipse;

[0091] Among them, the first preset distance is half of the center distance between the left eye ellipse and the right eye ellipse. Since the center distance between the left eye ellipse and the right eye ellipse is generally 65 mm, furthermore, the first preset distance is 32.5 mm.

[0092] After responding to the user's second intersection operation instruction, the first intersection line 203 where the outer contour line 201 of the left eye ellipse intersects the central plane 202 of the left eye ellipse can be obtained (as Figure 3 shown).

[0093] S1022, in response to the user's first projection operation instruction, display the first projection line 204 of the first intersection line 203 on the symmetric plane 200 (as Figure 3 shown);

[0094] S1023, in response to the user's third intersection operation instruction, display the second intersection line 206 between the symmetric plane 200 and the instrument screen plane 205 (as Figure 4 shown);

[0095] S1024, in response to the user's point copy operation instruction, display a plurality of points 207 on the second intersection line 206 (as Figure 5 shown);

[0096] S1025, in response to the user's operation instruction for the tangent of the curve, display a plurality of tangents 208 between the plurality of points 207 and the first projection line 204 (as Figure 6 shown);

[0097] It can be understood that after the first projection line 204 is in the symmetric plane and the plurality of points 207 are also in the same plane within the symmetric plane, the tangent from a certain point to the arc can be directly obtained through the tangent command.

[0098] S1026, in response to the user's fourth intersection operation instruction, display a plurality of intersection points 209 between the plurality of tangents 208 and the first projection line 204 (as Figure 6 shown);

[0099] S1027, in response to the user's second projection operation instruction, display the first projection points of the plurality of intersection points 209 on a plane parallel to the symmetric plane;

[0100] In the above embodiment, since the plane parallel to the symmetric plane is the central plane 202 of the left eye ellipse, thus, the first projection points 210 of the plurality of intersection points 209 on the central plane 202 of the left eye ellipse can be obtained. In another embodiment, the first projection points 211 of the plurality of intersection points 209 on the central plane 212 of the right eye ellipse can also be obtained (as Figure 7 shown).

[0101] S1028. In response to the user's point connection operation instruction, connect the first projection points (210 (left projection point), 211 (right projection point)) and a number of points 207 to obtain the left line of sight 213 from the left eye ellipse to the instrument screen surface 205, or the right line of sight 214 from the right eye ellipse to the instrument screen surface 205 (as Figure 8 shown).

[0102] It can be understood that after finding the tangent line 208 between the first projection line 204 located in the symmetry plane 200 and a number of points 207, a number of intersection points 209 between the first projection line 204 and the tangent line 208 can be found. Then, project the number of intersection points 209 onto the central plane 202 of the left eye ellipse, and the tangent point 210 on the first intersection line 203 intersecting with the central plane 202 of the left eye ellipse can be found. Or then project the number of intersection points 209 onto the central plane 212 of the right eye ellipse, and the tangent point 211 on the intersection line intersecting with the central plane 212 of the right eye ellipse can be found. Furthermore, connect a number of points 207 and each tangent point, and the tangent line 213 of the outer contour line intersecting with the central plane 202 of the left eye ellipse and the tangent line 214 of the outer contour line intersecting with the central plane 212 of the right eye ellipse can be obtained (as Figure 8 shown).

[0103] S1029. In response to the user's operation instruction to draw a normal line to the instrument screen surface 205 through a number of points, with the normal line as the symmetry line, display the reflected line 215 of the line of sight (as Figure 9 shown).

[0104] After obtaining the reflected line 215, in response to the user's shear operation instruction, the inner surface 216 of the instrument cover shears the reflected line to form a reflected line segment. In response to the user's first intersection operation instruction, the entry point 217 of the reflected line segment on the inner surface 216 of the instrument cover is obtained (as Figure 10 shown). Finally, it can be determined whether the design of the instrument cover meets the requirements by whether the entry points 217 are all on the inner surface 216 of the instrument cover (as Figure 11 shown. The fact that the entry points 217 are all within the inner surface 216 of the instrument cover indicates that the design meets the requirements).

[0105] In order to improve the accuracy of the verification and verify more reflected lines, in another embodiment, as Figure 12 shown, the plane parallel to the symmetry plane can also be other planes, which can be obtained through the following steps:

[0106] S201. In response to the user's extreme value seeking operation instruction, display the leftmost extreme point a and the rightmost extreme point b of the instrument screen surface 205 (as Figure 13 shown);

[0107] S202, in response to the user's parallel plane operation instruction, establish a first plane 301 parallel to the symmetry plane 200 through the leftmost pole a; establish a second plane 302 parallel to the symmetry plane 200 through the rightmost pole b (as Figure 13 shown);

[0108] S203, in response to the user's inter-plane operation instruction, establish a number of first equal division planes 303 between the first plane 301 and the symmetry plane 200, and establish a number of second equal division planes 304 between the second plane 302 and the symmetry plane 200.

[0109] After obtaining a number of first equal division planes 303 and second equal division planes 304, the line of sight and reflection line of each equal division plane can be obtained by taking the example of the central plane of the left eye ellipse as a reference.

[0110] It can be understood that, taking one of the equal division planes of the first equal division plane 303 as an example, first in response to the user's fifth intersection operation instruction, obtain the intersection line of this equal division plane and the outer contour line of the left eye ellipse, then in response to the user's third projection operation instruction, obtain the projection line of this intersection line on the symmetry plane 200, in response to the user's tangent operation instruction of the curve, obtain the tangents of several points on the intersection line of the symmetry plane 200 and the instrument screen plane and the projection line, in response to the user's sixth intersection operation instruction, obtain the intersection point of this tangent and the projection line, in response to the user's fourth projection operation instruction, project this intersection point onto the said equal division plane, connect several points on the intersection line of the symmetry plane 200 and the instrument screen plane and the projection tangent point on the equal division plane, and obtain the tangent of this equal division plane (i.e., the line of sight). Then in response to the user's plane normal operation instruction, obtain the normal of the instrument screen plane passing through several points on the intersection line of the symmetry plane 200 and the instrument screen plane, and take the normal as the symmetry line to obtain the symmetry line of the said tangent (i.e., the reflection line). After obtaining the reflection line, in response to the user's shearing operation instruction, make the inner surface 216 of the instrument cover shear the reflection line to form a reflected line segment, in response to the user's first intersection operation instruction, obtain the entry point 217 of the reflected line segment on the inner surface of the instrument cover (as Figure 15 shown), and finally it can be judged whether the design of the instrument cover meets the requirements by whether the entry points 217 are all on the inner surface 216 of the instrument cover.

[0111] Other equal division planes can be operated with reference to the above example. It is also possible to use the "Instantiate from Selection" of the "Super Copy" command, taking the above example as a template, using the instrument screen plane, symmetry plane, projection line, inner surface of the instrument cover and the plane to be obtained as input elements, and all the reflection lines and entry points corresponding to all the reflection points on all the planes can be obtained through super copy.

[0112] As Figure 15As shown, it is a schematic diagram where the incident points 217 are all within the inner surface 216 of the instrument cover, indicating that the parameter design of the instrument cover is reasonable. As Figure 16 As shown, it is a schematic diagram where part of the incident points 217 are outside the inner surface 216 of the instrument cover. It can be seen from the figure that part of the reflected rays 400 are located outside the inner surface of the instrument cover, indicating that the instrument cover cannot block this part of the reflected rays 400. It is verified that this part of the reflected rays 400 will affect the driver's line of sight.

[0113] In order to make the verification results more accurate, in another embodiment:

[0114] The outer contour line of the left eye ellipse is the outer contour line obtained by expanding the outer contour line of the left eye ellipse outward by a second preset distance; the outer contour line of the right eye ellipse is the outer contour line obtained by expanding the outer contour line of the right eye ellipse outward by a second preset distance.

[0115] Among them, the second preset distance can be 10 mm, or other values, and can be set according to the design parameters and requirements of the instrument cover itself.

[0116] That is to say, in the foregoing embodiment, the intersection line of each equidivision plane or the central plane of the left eye ellipse or the central plane of the right eye ellipse and the outer contour line of the corresponding eye ellipse can be the intersection line of the outer contour line that is 10 mm outward from the outer contour line of the corresponding eye ellipse. In this way, the range of the eye ellipse receiving reflected rays is expanded. If the design parameters of the inner surface of the instrument cover meet the requirements under the verification of the outer contour line of the eye ellipse (the general term for the left eye ellipse and the right eye ellipse), then they will definitely meet the requirements in other cases.

[0117] It should be noted that in order to ensure the accuracy of the verification results, in the above embodiment, several can be understood to include at least 20.

[0118] According to a specific embodiment of the present invention, the production premise: the verification of the interference of the instrument reflection on the driver's line of sight. The most unfavorable situation considered is when the driver is relatively tall (i.e., 95th percentile male). At this time, the driver's line of sight is emitted from the outer surface of the 95% eye ellipse.

[0119] Step 1. Prepare basic elements.

[0120] The basic elements used for verification by this tool are: the upper part of the 95% left eye ellipse, the symmetry plane of the left and right eye ellipses, the inner surface of the instrument cover, and the instrument screen surface, a total of 4 basic elements. The above 4 elements need to be processed for broken parameters.

[0121] (Eye ellipse *: The statistical distribution pattern of the eye positions of occupants of different body sizes sitting in the vehicle in a normal posture.)

[0122] Step 2. Set reflection points.

[0123] (1) As shown in Figure 13 , use the "extreme value" command to find the leftmost and rightmost poles of the instrument screen surface 205, and establish planes 301 and 302 parallel to the symmetry plane 200 through these poles.

[0124] (2) As shown in Figure 14 , use the "plane between planes" command to establish 15 equally spaced planes 303 (E1 to E 15 ) and 304 (E 16 to E 30 ) between the symmetry plane 200 and plane 301 and between the symmetry plane 200 and plane 302 respectively.

[0125] (3) As shown in Figure 3 , since the distance between the left and right eye ellipse centers is 65 mm and the left and right eye ellipses are symmetric about the center plane, the distance from the left eye ellipse center is found to be 65 mm / 2 = 32.5 mm. Shift the symmetry plane 200 32.5 mm to the left to obtain the center plane 202 of the left eye ellipse.

[0126] (4) To simulate the deviation of the actual position of the driver's eyes, shift the left eye ellipse 10 mm outward to obtain the expanded outer contour. Intersect the expanded outer contour with the center plane 202 of the left eye ellipse to obtain the outer contour line, and project the outer contour line onto the symmetry plane 200 to obtain the projection line.

[0127] Step 3. Find the line of sight reflection line of the symmetry plane 200.

[0128] (1) As shown in Figure 4 and Figure 5 , use the "intersection command" to obtain the intersection line 206 of the symmetry plane 200 and the instrument screen surface 205. Use the "point copy" command to obtain 30 evenly spaced points 207 (points K1 to K 30 ) on the intersection line 206.

[0129] (2) As shown in Figure 6 , respectively starting from the 30 points 207 (points K1 to K 30 ), use the "tangent of curve" mode in "line definition" to obtain the tangents 208 (L1 to L 30 ) of the 30 points 207 (points K1 to K 30 ) and the projection line 204, that is, the line of sight. Use the "intersection command" to obtain the intersection points 209 (M1 to M 30 ) of the tangent 208 and the projection line 204.

[0130] (3) As shown in Figure 7As shown in the figure, the symmetry plane 200 is offset 32.5 mm to the left and right sides respectively to obtain the left-eye ellipse center plane 202 and the right-eye ellipse center plane 212. The intersection point 209 (M1 to M 30 ) is projected onto the left-eye ellipse center plane 202 and the right-eye ellipse center plane 212 respectively, and the projection points 210 (N1 to N 30 ) and 211 (O1 to O 30 ) are obtained.

[0131] (4) As Figure 8 shown, the projection points 210 (N1 to N 30 ) and 211 (O1 to O 30 ) are connected to the 30 points 207 (points K1 to K 30 ) with corresponding serial numbers respectively (such as N1 and K1, O1 and K1, N2 and K2), and the straight lines 213 (P1 to P 30 ) and 214 (Q1 to Q 30 ) are obtained.

[0132] (5) Using the "normal of curve" command in "line definition", the normals R1 to R 30 of the instrument screen surface 205 passing through the 30 points 207 (points K1 to K 30 ) are obtained.

[0133] (6) As Figure 9 shown, using the "symmetry" command, with the normals R1 to R 30 as the reference curves, the symmetry lines of the straight lines 213 (P1 to P 30 ) and 214 (Q1 to Q 30 ) with respect to the normals R1 to R 30 are obtained, which are the reflection lines of the line of sight.

[0134] (7) As Figure 10 and Figure 11 shown, all the reflection lines are joined and cut by the inner surface 216 of the instrument cover to obtain the reflection line segments, and then the "intersection" command is performed on the line segments and the inner surface 216 of the instrument cover, and the entry points 217 of the line of sight on the inner surface of the instrument cover are obtained.

[0135] Step 4. Find the reflection lines corresponding to all the reflection points on all the planes (E1 to E 30 ).

[0136] Using the "instantiate from selection" of the "super copy" command, taking Step 3 as the template, with the symmetry plane 200, the instrument screen surface 205, the inner surface 216 of the instrument cover, the projection line and any one of the planes to be obtained (E1 to E 30 ) as the input elements, after 30 times of super copying, all the planes (E1 to E 30)The reflected rays and the incident points corresponding to all the reflection points above.

[0137] Step 5. By analyzing the distribution of the obtained reflected rays and reflection points, the line-of-sight verification result can be obtained.

[0138] As Figure 15 shown, when all the reflected rays are within the inner surface area of the instrument cover, it indicates that the inner surface of the instrument cover can effectively block the reflections of surrounding objects, and the result is OK.

[0139] As Figure 16 shown, when some of the reflected rays pass through the outside of the instrument cover, it indicates that the inner surface of the instrument cover cannot effectively block the reflections of some surrounding objects, and the result is NG.

[0140] Therefore, the verification method proposed in the embodiment of the present invention can be used for the field-of-view verification of instruments and instrument covers with different shapes and forms, which has promotional significance and fills the gap in the field-of-view verification tools for instruments and instrument covers: Using this method, the result can be obtained within half an hour, which can greatly reduce the working hours and improve the design efficiency. It overcomes the technical defects of the traditional method with low efficiency and large result deviation. And the obtained verification result is intuitive and easy to understand, which is convenient for designers to directly judge whether the designed parts meet the requirements. In addition, the verification method proposed in the embodiment of the present invention has the simulation of the line of sight. For specific reference, see the result examples in the attached Figure 15 and 16 , which are the simulation results of different line-of-sight emissions and reflected rays.
