[0002] While driving, users can view relevant status information through the instrument cluster to monitor the vehicle's condition.

Detailed Implementation

[0046] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0047] The instrument cluster is a display system used to show the overall operating status of the vehicle. It typically includes a speedometer, engine tachometer, fuel gauge, coolant temperature gauge, air pressure gauge, and various vehicle status alerts or warning symbols. Therefore, users can monitor the vehicle's operating status by checking the instrument cluster while driving.

[0048] Typically, the instrument cluster is positioned in front of the steering wheel, requiring the user to view it through the steering wheel's visible area. In other words, the steering wheel obstructs the view of the instrument cluster to some extent. However, the degree of obstruction varies for users of different body types. Therefore, the following technical challenge exists during vehicle development: how to ensure that the designed instrument cluster position is universally applicable to meet the viewing requirements of users of different body types.

[0049] To address the issue of ensuring the universality of instrument cluster design locations during vehicle development, this invention discloses a method, apparatus, and computer-readable storage medium for determining the display area of ​​an instrument cluster.

[0050] The following is an exemplary description of the method for determining the display area of ​​the instrument cluster disclosed in the embodiments of the present invention. Figure 1 A flowchart illustrating a method for determining the display area of ​​a combination instrument cluster according to an embodiment of the present invention is shown. This method is executed by a device for determining the display area of ​​the combination instrument cluster. Figure 1 As shown, the method includes the following steps:

[0051] Step 110: Obtain the first simulated data of the steering wheel, the second simulated data of the user's eye ellipse, and the third simulated data of the instrument cluster display.

[0052] The method for determining the display area of ​​the instrument cluster disclosed in this invention can be implemented using vehicle design simulation software. For example, it can be implemented in software such as CAITA, UG, RAMSSIS, CAVA, and OPTIS.

[0053] In this invention, the steering wheel refers to the simulated steering wheel in the vehicle design simulation software. The first simulation data of the steering wheel may include the position information, angle information, and size information of the steering wheel.

[0054] The eye ellipse refers to the statistical distribution of eye positions of users of different body types (such as drivers) when they are sitting in a car in a normal posture.

[0055] The eye ellipse can be divided into different percentile eye ellipses. The percentile is determined as follows: A sufficient number of drivers of different heights are seated in suitable driving positions, and their eye point positions are recorded. The eye points of N% of these drivers fit the eye envelope, commonly known as the N-percentile eye ellipse. For example, if 95 out of 100 drivers of different heights have their eye points within this eye ellipse's envelope, it is called the 95th percentile eye ellipse. Similarly, if 99 out of 100 drivers of different heights have their eye points within this eye ellipse's envelope, it is called the 99th percentile eye ellipse.

[0056] The present invention can use a 90th percentile eye ellipse, a 95th percentile eye ellipse, or a 99th percentile eye ellipse, which can basically cover the eye position of drivers of different heights.

[0057] The user's eye ellipse may include two eye ellipses: a left eye ellipse (also known as the first eye ellipse) and a right eye ellipse (also known as the second eye ellipse). Both the left and right eye ellipses include a central eye point. In this invention, the simulated data corresponding to the central eye point of either the left or right eye ellipse can be referred to as the central eye point simulated data.

[0058] Taking the two eye ellipses as a whole, the simulation data also includes the limiting eye points. The simulation data corresponding to these limiting eye points is called the limiting eye point simulation data. For example, the eye point at the uppermost point of the two eye ellipses is called the upper limiting eye point, the eye point at the lowermost point is called the lower limiting eye point, the eye point at the leftmost point is called the left limiting eye point, and the eye point at the rightmost point is called the right limiting eye point. Correspondingly, the simulation data corresponding to the upper limiting eye point is called the upper limiting eye point simulation data, the simulation data corresponding to the lower limiting eye point is called the lower limiting eye point simulation data, the simulation data corresponding to the left limiting eye point is called the left limiting eye point simulation data, and the simulation data corresponding to the right limiting eye point is called the right limiting eye point simulation data.

[0059] The instrument cluster display surface refers to the surface on which the display area of ​​the instrument cluster is located. Third-party simulation data may include the position, angle, and dimensions of the instrument cluster display surface.

[0060] It should be noted that the surface where the display area of ​​the instrument cluster is located is known in this invention, and the goal is to determine the location of the display area of ​​the instrument cluster on this surface.

[0061] It should also be noted that if the above steps are performed in vehicle design simulation software, after obtaining the first, second, and third simulation data, the simulated steering wheel, user eye ellipse, and instrument cluster display can be displayed on the display interface of the vehicle design simulation software. Furthermore, the relative positions of the steering wheel, user eye ellipse, and instrument cluster display can be ensured to satisfy certain positional relationships.

[0062] For example, such as Figure 2 As shown, the simulated steering wheel 100, user eye ellipse 200, and instrument cluster display surface 300, along with their relative positions, can be displayed on the vehicle design simulation software's interface. The steering wheel 100 is positioned between the user eye ellipse 200 and the instrument cluster display surface 300.

[0063] Step 120: Based on the first simulation data, the third simulation data, and the center eye point simulation data, determine the center field of view area corresponding to the visible area of ​​the steering wheel on the instrument cluster display surface.

[0064] like Figure 2 As shown, the visible area 101 of the steering wheel can be a hollowed-out area located at the top of the steering wheel, which is enclosed by a portion of the steering wheel's inner tangent and the upper boundary lines of the two lateral spokes. During actual driving, the user views the instrument cluster through the visible area 101 of the steering wheel.

[0065] like Figure 2 As shown, with the central eye point 201 as the user's eye position, the visible area 101 through the steering wheel is determined, and the area that can be seen on the instrument cluster display surface 300 is the central field of vision area 301.

[0066] Step 130: Based on the central eyepoint simulation data, at least one extreme eyepoint simulation data, and the third simulation data, the central visual field region 301 is translated to obtain at least one extreme visual field region corresponding to at least one extreme eyepoint simulation data.

[0067] The central visual field region 301 corresponds to the central eye point 201. Therefore, based on this correspondence, the limiting visual field region corresponding to each limiting eye point can be determined.

[0068] This invention translates a pre-determined central visual field region 301, so that the translated region corresponds to the simulation data of each extreme eye point. For example, as... Figure 3 As shown, based on the upper limit eyepoint simulation data, after shifting a pre-determined central visual field region, the upper limit visual field region 302 corresponding to the upper limit eyepoint simulation data is obtained. For example, based on the lower limit eyepoint simulation data, after shifting a pre-determined central visual field region, the lower limit visual field region 303 corresponding to the lower limit eyepoint simulation data is obtained. For example, based on the left limit eyepoint simulation data, after shifting a pre-determined central visual field region, the left limit visual field region 304 corresponding to the left limit eyepoint simulation data is obtained. For example, based on the right limit eyepoint simulation data, after shifting a pre-determined central visual field region, the right limit visual field region 305 corresponding to the right limit eyepoint simulation data is obtained.

[0069] In this way, after translation, we can obtain the number of limiting field-of-view regions corresponding to the limiting eyepoint simulation data. For example, such as Figure 3 As shown, four limiting visual fields are obtained, namely the upper limiting visual field region 302, the lower limiting visual field region 303, the left limiting visual field region 304, and the right limiting visual field region 305.

[0070] Step 140: Determine the display area of ​​the instrument cluster based on the central field of view 301 and at least one extreme field of view area.

[0071] like Figure 3 As shown, taking the four limiting visual field regions—upper limiting visual field region 302, lower limiting visual field region 303, left limiting visual field region 304, and right limiting visual field region 305—as an example, a minimum visual field region (corresponding to) can be determined based on the intersection of the central visual field region 301, upper limiting visual field region 302, lower limiting visual field region 303, left limiting visual field region 304, and right limiting visual field region 305. Figure 3 (The area filled with diagonal lines). In this way, the minimum field of vision area can meet the vision requirements of different eye positions, that is, most users can see the minimum field of vision area completely through the visible area 101 of the steering wheel.

[0072] In this way, the display area of ​​the instrument cluster can be set at any position within the minimum field of view. If the area of ​​the instrument cluster's display area is larger than the area of ​​the minimum field of view, the display area of ​​the instrument cluster can be made to extend evenly beyond the boundary of the minimum field of view, based on the aforementioned minimum field of view.

[0073] In summary, the method for determining the display area of ​​a combination instrument panel disclosed in this invention, based on simulated data of the central eye point of the eye ellipse and simulated data of at least one extreme eye point, determines the display area of ​​the combination instrument panel, which can meet the field of vision requirements of users of different body types, making the design position of the combination instrument panel universal. Furthermore, this invention first determines a central field of vision region corresponding to the central eye point based on the simulated data of the central eye point of the eye ellipse, and then determines the extreme field of vision regions corresponding to each extreme eye point by translating the central field of vision region. This avoids repeated calculations of the field of vision region, thereby reducing the computational load.

[0074] Figure 4 A flowchart of another embodiment of a method for determining the display area of ​​a combination instrument provided by the present invention is shown, in conjunction with... Figure 1 ,like Figure 4 As shown, Figure 1 Step 120 may specifically include the following steps 1201-1203.

[0075] Step 1201: Based on the first simulation data, determine the visible area of ​​the steering wheel.

[0076] The first simulation data includes data characterizing the position, angle, and size of the steering wheel 100. Therefore, the visible area of ​​the steering wheel can be extracted based on the first simulation data.

[0077] Combination Figure 2 and Figure 5 As shown, a tangent line L can be drawn first through the upper limit eye point 202. 切 Tangent L 切 Tangent to the inner surface of the steering wheel 100, the tangent point M is obtained. Then, through the tangent point M, a plane parallel to the steering wheel is drawn to obtain the steering plane 102. Furthermore, on the steering plane 102, the area enclosed by a portion of the inner tangent of the steering wheel 100 and the upper boundary lines of the two lateral spokes is the visible area 101 of the steering wheel.

[0078] Step 1202: Determine the projection scaling ratio based on the visible area of ​​the steering wheel, the third simulation data, and the center eye point simulation data.

[0079] In one possible implementation, such as Figure 2 As shown, a first distance from the center eye point 201 to the visible area 101 of the steering wheel can be determined based on the visible area 101 of the steering wheel and the simulated data of the center eye point; and a second distance from the center eye point 201 to the instrument cluster display surface 300 can be determined based on the third simulated data and the simulated data of the center eye point. Thus, based on the first and second distances, the projection scaling ratio corresponding to projecting the visible area 101 of the steering wheel onto the instrument cluster display surface 300 can be determined.

[0080] The projection scaling ratio can be the ratio of the first distance to the second distance, or it can be further calculated and determined based on the ratio of the first distance to the second distance. This invention does not limit this.

[0081] Step 1203: Based on the projection scaling ratio, project the visible area of ​​the steering wheel onto the instrument cluster display surface to obtain the central field of view area.

[0082] In one possible implementation, the central visual field region 301 can be determined based on the projection scaling ratio and the simulated central eye point data corresponding to the left eye ellipse, or the simulated central eye point data corresponding to the right eye ellipse.

[0083] For example, such as Figure 2 As shown, the center eye point 201 corresponding to the left eye ellipse can be used as the projection point. According to the projection scaling ratio, the visible area 101 of the steering wheel can be projected onto the instrument cluster display surface 300 to obtain the central field of view area 301.

[0084] In one possible approach, a sub-central visual field region can be determined based on the simulated central eye point data corresponding to the left eye ellipse and the simulated central eye point data corresponding to the right eye ellipse, respectively. Then, the union of the two sub-central visual field regions is determined as the central visual field region.

[0085] For ease of description, the simulated data of the center eye point corresponding to the left eye ellipse is referred to as the first center eye point simulation data, and the simulated data of the center eye point corresponding to the right eye ellipse is referred to as the second center eye point simulation data.

[0086] For example, such as Figure 6 As shown, based on the first center eye point simulation data and the projection scaling ratio, the visible area 101 of the steering wheel is projected onto the instrument cluster display surface 300 to obtain the first sub-center field of view area 3011. Based on the second center eye point simulation data and the projection scaling ratio, the visible area of ​​the steering wheel is projected onto the instrument cluster display surface to obtain the second sub-center field of view area 3012. Finally, the union of the first sub-center field of view area 3011 and the second sub-center field of view area 3012 is determined as the center field of view area 301.

[0087] In summary, the method for obtaining the central field of view region 301 provided by the present invention can first determine the visible area 101 of the steering wheel on the steering plane 102, and then project the visible area 101 of the steering wheel onto the instrument cluster display surface 300 by means of proportional scaling, thereby obtaining the central field of view region 301 on the instrument cluster display surface 300. In this way, no complicated calculations are required and the method is simple.

[0088] Figure 7 A flowchart of another embodiment of a method for determining the display area of ​​a combination instrument provided by the present invention is shown, in conjunction with... Figure 1 ,like Figure 7 As shown, Figure 1 Step 130 may specifically include the following steps 1301-1303.

[0089] Step 1301: Determine the reference intersection point based on the simulation data of the central eye point and the simulation data of the first feature point.

[0090] The first feature point simulation data can be point simulation data located at any point on the steering wheel 100. For example, the first feature point simulation data can be point simulation data located between the inner and outer tangent surfaces of the steering wheel 100.

[0091] In one feasible approach, a central field of view can be established first based on the simulated data of the central eye point and the simulated data of the first feature point; then, a reference intersection point can be determined based on the central field of view and the display surface of the instrument cluster.

[0092] For example, such as Figure 8 As shown, a central field of view L1 is established through the central eye point 201 and the first feature point 103. After the central field of view L1 is extended, it intersects with the instrument panel display surface at a point, which is the reference intersection point A.

[0093] Here, the central eye point 201 refers to the eye point position corresponding to the central eye point simulation data, and the first feature point 103 refers to the feature point position corresponding to the first feature point simulation data.

[0094] Step 1302: Based on the simulation data of the first feature point and the simulation data of at least one extreme eye point, determine at least one extreme intersection point respectively.

[0095] Similarly, determining at least one extreme intersection point can be done in the following way: first, establish at least one extreme field of view line based on the simulation data of the first feature point and the simulation data of at least one extreme eye point; then, determine at least one extreme intersection point based on the at least one extreme field of view line and the display surface of the instrument cluster.

[0096] For example, consider extreme eyepoint simulation data including upper extreme eyepoint simulation data, lower extreme eyepoint simulation data, left extreme eyepoint simulation data, and right extreme eyepoint simulation data. Figure 8 As shown, an upper limit field of view L2 is established through the upper limit eye point 202 and the first feature point 103. The upper limit field of view L2 extends and intersects the instrument cluster display surface 300 at a point, which is the upper limit intersection point B. A lower limit field of view L3 is established through the lower limit eye point 203 and the first feature point 103. The lower limit field of view L3 extends and intersects the instrument cluster display surface 300 at a point, which is the lower limit intersection point C.

[0097] Figure 9 for Figure 8 Top view, such as Figure 9 As shown, a left limit field of view L4 is established through the left limit eye point 204 and the first feature point 103. The left limit field of view L4 extends and intersects the instrument cluster display surface 300 at a point, which is the left limit intersection point D. A left limit field of view L5 is established through the right limit eye point 205 and the first feature point 103. The right limit field of view L5 extends and intersects the instrument cluster display surface 300 at a point, which is the right limit intersection point E.

[0098] It should be noted that the reference intersection point A, upper limit intersection point B, lower limit intersection point C, left limit intersection point D, and right limit intersection point E formed by the intersection with the instrument cluster display surface 300 are all located on the instrument cluster display surface 300.

[0099] Step 1303: Using the reference intersection point A as the positioning point, based on the reference intersection point A and each extreme intersection point, translate the central field of view region 301 to obtain the extreme field of view region corresponding to each extreme intersection point.

[0100] It should be noted that the central field of view region 301 is determined based on the central eye point 201, and the reference intersection point A is also determined based on the central eye point 201. In other words, the central field of view region 301 corresponds to the reference intersection point A. Based on this correspondence, the limiting field of view region corresponding to each limiting intersection point can be obtained in the following way.

[0101] In one possible implementation, the reference intersection point A and the central field of view region 301 can be translated as a whole. Specifically, during the translation, the reference intersection point A is used as the positioning point. For example, the reference intersection point A is positioned to the upper limit intersection point B. Then, as the reference intersection point A moves to the upper limit intersection point B, the central field of view region 301 is translated accordingly, thus obtaining the upper limit field of view region 302 corresponding to the upper limit intersection point B. Similarly, the reference intersection point A is positioned to the lower limit intersection point C. Then, as the reference intersection point A moves to the lower limit intersection point C, the central field of view region 301 is translated accordingly, thus obtaining the lower limit field of view region 303 corresponding to the lower limit intersection point C. Using the same method, the left limit field of view region 304 and the right limit field of view region 305 can be obtained, which will not be elaborated here.

[0102] In one possible implementation, the distances between the reference intersection point A and each extreme intersection point can be determined first. Then, the central field of view region 301 can be translated according to the corresponding distances to obtain the corresponding extreme field of view regions. For example, if the distance between the reference intersection point A and the upper extreme intersection point B is S1, then translating the central field of view region upwards by a distance of S1 yields the upper extreme field of view region 302. Using the same method, the lower extreme field of view region 303, the left extreme field of view region 304, and the right extreme field of view region 305 can be obtained, which will not be elaborated here.

[0103] In summary, the method for obtaining the limiting field of view area provided by this invention involves determining the intersection points corresponding to the central eye point and the limiting eye points on the instrument cluster display surface, and then, based on the correspondence between the central eye point and the central field of view area, shifting the central field of view area to obtain the limiting field of view area corresponding to each limiting eye point. In this way, each limiting field of view area can be determined simply by shifting the central field of view area; the method is simple and does not require complex calculations.

[0104] Figure 10 A flowchart of another embodiment of a method for determining the display area of ​​a combination instrument cluster provided by the present invention is shown. This method can further modify step 140, which determines the display area of ​​the combination instrument cluster. Figure 10 As shown, the method for determining the display area of ​​the instrument cluster may include steps 150-180 in addition to the steps 110-140 described above.

[0105] Step 150: Obtain simulation data of the upper boundary point of the airbag.

[0106] For vehicles equipped with airbags, the airbags are generally located between the steering wheel and the instrument cluster display surface, and near the lower side of the steering wheel.

[0107] For example, such as Figure 5 As shown, the airbag 400 is located between the steering wheel 100 and the instrument cluster display surface 300. The user can see a portion of the airbag 400 through the visible area 101 of the steering wheel. Thus, the airbag 400 may also obstruct the user's view of the instrument cluster. Therefore, this invention further modifies the instrument cluster display area determined in step 140 to eliminate the obstruction caused by the airbag 400.

[0108] like Figure 11 As shown, the upper boundary point 401 of the airbag refers to the point that is tangent to the upper boundary of the airbag 400 through the lower limit eye point 203.

[0109] Step 160: Determine the first corrected intersection point based on the simulation data of the second feature point and the simulation data of the upper limit eye point.

[0110] like Figure 11 As shown, the second feature point 104 can be any point located on the inner tangent surface or inner tangent line of the steering wheel 100.

[0111] In one feasible approach, the first modified intersection point can be determined in the following manner: (e.g.) Figure 11 As shown, firstly, based on the simulation data of the second feature point and the simulation data of the upper limit eye point, the upper field of view line L6 is established; then, after the upper field of view line L6 is extended, it intersects with the instrument panel display surface 300 at a point, which is the first corrected intersection point F.

[0112] The first corrected intersection point F is located on the instrument cluster display surface 300.

[0113] It should be noted that the method for obtaining the limiting field of view provided by this invention can be combined with... Figure 7 The specific implementation of step 130 is shown below. Correspondingly, the first feature point 103 can be any point located between the inner and outer tangent surfaces of the steering wheel 100. For example, the first feature point 103 can be the center point located between the inner and outer tangent surfaces of the steering wheel 100. The first feature point 103 and the second feature point 104 can be located on the same radius of the steering wheel 100 or on an extension of the same radius.

[0114] Thus, when the first feature point 103 is located between the inner and outer tangent surfaces of the steering wheel 100, and the second feature point 104 is located on the inner tangent surface or inner tangent line of the steering wheel 100, and the first feature point 103 and the second feature point 104 are located on the same radius or the extension line of the same radius of the steering wheel 100, it is possible to first adopt... Figure 7 The method shown determines the display area of ​​the instrument cluster, and then steps 150 to 180 are used to further correct the display area of ​​the instrument cluster determined in step 140, so that the corrected display area of ​​the instrument cluster can be more accurate.

[0115] Step 170: Based on the simulation data of the upper boundary point and the lower limit eye point of the airbag, determine the second corrected intersection point.

[0116] In one feasible approach, the second modified intersection point can be determined in the following manner: (e.g.) Figure 11 As shown, firstly, based on the simulation data of the upper boundary point of the airbag and the simulation data of the lower limit eye point, the lower field of view line L7 is established; then, after the upper field of view line L7 is extended, it intersects with the instrument cluster display surface 300 at a point, which is the second corrected intersection point G.

[0117] The second corrected intersection point G is located on the instrument cluster display surface 300.

[0118] Step 180: Based on the first correction intersection point F and the second correction intersection point G, correct the display area of ​​the instrument cluster.

[0119] like Figure 12 As shown, based on step 160 above, a first corrected intersection point F is obtained above the display area 306 of the instrument cluster. Based on step 170 above, a second corrected intersection point G is obtained below the display area 306 of the instrument cluster.

[0120] In one possible implementation, the display area 306 of the instrument cluster is corrected based on the first corrected intersection point F and the second corrected intersection point G, which can be achieved in the following way:

[0121] First, based on the first corrected intersection point F, the display area 306 of the instrument cluster is translated to obtain the first display area; the upper edge of the first display area intersects with the first corrected intersection point F.

[0122] For example, such as Figure 13 As shown, the display area 306 of the instrument cluster is translated upward along the Y-axis until the upper edge of the display area 306 of the instrument cluster intersects with the first correction intersection point F, thus obtaining the first display area 3061.

[0123] Using a similar method, based on the second corrected intersection point G, the display area of ​​the instrument cluster is translated to obtain the second display area;

[0124] For example, such as Figure 13 As shown, the display area 306 of the instrument cluster is translated downward along the Y-axis until the lower edge of the display area 306 of the instrument cluster intersects with the second correction intersection point G, thus obtaining the second display area 3062.

[0125] Finally, the union of the first display area 3061, the second display area 3062, and the display area 306 of the original instrument cluster is determined as the display area of ​​the corrected instrument cluster.

[0126] In summary, the method for determining the display area of ​​the instrument cluster provided by this invention introduces simulated data of the upper boundary point of the airbag and simulated data of the second feature point to correct the display area of ​​the instrument cluster, making the corrected display area of ​​the instrument cluster more accurate.
