Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
The combination meter is a display system for displaying the running state of the whole vehicle and generally comprises a speedometer, an engine tachometer, an oil meter, a water temperature meter, a barometer and a plurality of vehicle condition reminding or alarming signs. Therefore, the user can grasp the state operation of the vehicle by looking at the combination meter in the driving process of the vehicle.
Typically, the cluster is positioned in front of the steering wheel such that the user needs to look through the viewable area of the steering wheel. That is, the steering wheel may cause some obstruction to the view of the cluster. However, for users of different sizes, the range of shielding of the steering wheel is different, and therefore, there are the following technical difficulties in the vehicle development process: how to ensure that the position of the designed combination meter has universality so as to meet the visual field requirements of users with different body types.
In order to solve the problem that the design position of the combination instrument has universality in the vehicle development process, the invention discloses a method and a device for determining the display area of the combination instrument and a computer readable storage medium.
The method for determining the display area of the combination meter disclosed in the embodiment of the invention is exemplified below. Fig. 1 shows a flowchart of a method for determining a display area of a cluster, which is performed by a device for determining a display area of a cluster according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step 110: and acquiring first simulation data of the steering wheel, second simulation data of the eye ellipse of the user and third simulation data of the display surface of the combination instrument.
The method for determining the display area of the combination instrument disclosed by the invention can be realized based on vehicle design simulation software. For example, it may be implemented in software such as CAITA, UG, RAMSSIS, CAVA, OPTIS.
In the invention, the steering wheel refers to a corresponding simulated steering wheel in vehicle design simulation software, and the first simulation data of the steering wheel can comprise position information, angle information, size information and the like of the steering wheel.
An eye ellipse refers to a pattern of statistical distribution of eye positions of users (e.g., drivers) of different sizes when sitting in a vehicle in a normal posture.
Wherein the eye ellipses can be divided into different percentile eye ellipses. Wherein the percentile is determined by: drivers of different heights of sufficient cardinality sit in the appropriate riding position and record their eye point positions, where N% of the eye points fit to the envelope of the eyes, commonly known as N percentile eye ellipses. For example, 100 driver eyepoints of different heights, 95 of which are within the envelope of this eye ellipse, are referred to as 95 percent eye ellipses. For another example, 100 driver eyepoints of different heights, 99 of which are within the envelope of the eye ellipse, are referred to as 99 percentile eye ellipses.
The invention may employ a 90 percentile eye ellipse, a 95 percentile eye ellipse, or a 99 percentile eye ellipse, which may substantially cover eye positions of drivers of different heights.
Wherein the user eye ellipses may include two eye ellipses, a left eye ellipse (which may also be referred to as a first eye ellipse) and a right eye ellipse (which may also be referred to as a second eye ellipse). The left eye ellipse and the right eye ellipse each include a center eye point, and in the present invention, the simulation data corresponding to the center eye point of the left eye ellipse or the right eye ellipse may be referred to as center eye point simulation data.
The method is characterized by taking the whole of two eye ellipses as objects, and further comprising limit eyepoints, wherein simulation data corresponding to the limit eyepoints are called limit eyepoint simulation data. For example, an eye point located at the uppermost end of two eye ellipses is referred to as an upper limit eye point, an eye point located at the lowermost end of two eye ellipses is referred to as a lower limit eye point, an eye point located at the leftmost end of two eye ellipses is referred to as a left limit eye point, and an eye point located at the rightmost end of two eye ellipses is referred to as a right limit eye point. Correspondingly, the simulation data corresponding to the upper limit eyepoint is the upper limit eyepoint simulation data, the simulation data corresponding to the lower limit eyepoint is the lower limit eyepoint simulation data, the simulation data corresponding to the left limit eyepoint is the left limit eyepoint simulation data, and the simulation data corresponding to the right limit eyepoint is the right limit eyepoint simulation data.
The display surface of the combination meter is a surface where a display area of the combination meter is designed. The third analog data may include position information, angle information, size information, and the like of the display surface of the cluster.
The display area of the cluster is known on the surface of the cluster in the present invention, and the object is to determine the position of the display area of the design cluster on the surface.
If the steps are executed in the vehicle design simulation software, the simulated steering wheel, the user eye ellipse, and the combination meter display surface may be displayed in the display interface of the vehicle design simulation software after the first simulation data, the second simulation data, and the third simulation data are acquired. And the positions of the steering wheel, the eye ellipse of the user and the display surface of the combination instrument can meet the relative position relation.
For example, as shown in fig. 2, the simulated steering wheel 100, the user's eye ellipse 200, the cluster display surface 300, and the relative positions between the three may be displayed on a display interface of the vehicle design simulation software. Wherein the steering wheel 100 is located between the user's eye ellipse 200 and the cluster display surface 300.
Step 120: and determining a corresponding central visual field area of the visual area of the steering wheel on the display surface of the combined instrument based on the first simulation data, the third simulation data and the central eyepoint simulation data.
As shown in fig. 2, the visible area 101 of the steering wheel may be a hollowed-out area located at the upper portion of the steering wheel, the hollowed-out area being an area defined by a partial inner tangent line of the steering wheel and upper boundary lines of two spokes in the lateral direction. During actual driving, the user views the combination meter through the visible area 101 of the steering wheel.
As shown in fig. 2, the visual area 101 passing through the steering wheel is defined by using the center eyepoint 201 as the eye position of the user, and the area visible on the combination meter display surface 300, that is, the center visual field area 301 is defined.
Step 130: based on the center eyepoint simulation data, the at least one limit eyepoint simulation data, and the third simulation data, the center field of view 301 is translated to obtain at least one limit field of view corresponding to the at least one limit eyepoint simulation data, respectively.
Since the central visual field area 301 corresponds to the central eyepoint 201, the limit visual field area corresponding to each limit eyepoint can be determined based on such a correspondence relationship.
The present invention translates the predetermined center field of view region 301 such that the translated region corresponds to each of the extreme eyepoint simulation data, respectively. For example, as shown in fig. 3, the upper limit visual field area 302 corresponding to the upper limit visual field simulation data is obtained after shifting the predetermined central visual field area based on the upper limit visual field simulation data. For another example, the lower limit visual field area 303 corresponding to the lower limit visual field simulation data is obtained after shifting the predetermined central visual field area based on the lower limit visual field simulation data. For another example, the left-limit visual field area 304 corresponding to the left-limit eyepoint simulation data is obtained by shifting the predetermined center visual field area based on the left-limit eyepoint simulation data. For another example, the right-limit visual field area 305 corresponding to the right-limit visual field simulation data is obtained by shifting the predetermined center visual field area based on the right-limit visual field simulation data.
Thus, after the translation, the number of limited visual field areas corresponding to the limited eyepoint simulation data can be obtained. For example, as shown in fig. 3, four limited visual field areas, that is, an upper limited visual field area 302, a lower limited visual field area 303, a left limited visual field area 304, and a right limited visual field area 305 are obtained.
Step 140: the display area of the cluster is determined based on the center field of view area 301 and the at least one limit field of view area.
As shown in fig. 3, taking four limiting field areas, an upper limiting field area 302, a lower limiting field area 303, a left limiting field area 304, and a right limiting field area 305 as an example, one minimum field area (corresponding to the diagonal-fill area in fig. 3) can be determined based on the intersection of the center field area 301, the upper limiting field area 302, the lower limiting field area 303, the left limiting field area 304, and the right limiting field area 305. In this way, the minimum field of view area can meet the field of view requirements of different eyepoint locations, i.e., most users can see the minimum field of view area entirely through the viewable area 101 of the steering wheel.
Thus, the display area of the combination meter can be set at an arbitrary position within the minimum field of view area. If the area of the display area of the combination meter is larger than the area of the minimum visual field area, the display area of the combination meter may be made equal to exceed the boundary of the minimum visual field area with reference to the minimum visual field area.
In summary, the method for determining the display area of the combination instrument disclosed by the invention is based on the central eyepoint simulation data and at least one limit eyepoint simulation data of the eye ellipse, and the determined display area of the combination instrument can meet the visual field requirements of users with different body types, so that the design position of the combination instrument has universality. In addition, the invention firstly determines a central visual field area corresponding to the central eye point based on the central eye point simulation data of the eye ellipse, and then determines limit visual field areas corresponding to the limit eye points in a mode of translating the central visual field area, thus avoiding repeated calculation of the visual field areas and reducing the calculation amount.
Fig. 4 is a flowchart illustrating another embodiment of a method for determining a display area of a cluster meter according to the present invention, and referring to fig. 1, as shown in fig. 4, step 120 in fig. 1 may specifically include the following steps 1201-1203.
Step 1201: based on the first simulation data, a visible area of the steering wheel is determined.
The first simulation data includes data characterizing the position, angle, and size of the steering wheel 100. Thus, the visual area of the steering wheel can be extracted based on the first analog data.
As shown in fig. 2 and 5, a tangent line L may be first drawn through the upper limit eyepoint 202 Cutting and cutting Tangent line L Cutting and cutting Tangential to the inner tangent plane of steering wheel 100, resulting in a tangent point M. Then, a plane parallel to the steering wheel is made through the tangent point M, resulting in a steering plane 102. Further, on the steering plane 102, an area formed by the partial inner tangent of the steering wheel 100 and the upper boundary lines of the two lateral spokes is a visible area 101 of the steering wheel.
Step 1202: the projection scale is determined based on the viewable area of the steering wheel, the third simulation data, and the center eyepoint simulation data.
In one implementation, as shown in fig. 2, a first distance of the center eyepoint 201 from the visible region 101 of the steering wheel may be determined based on the visible region 101 of the steering wheel and the center eyepoint simulation data; and determining a second distance of the center eyepoint 201 from the cluster display surface 300 based on the third simulation data and the center eyepoint simulation data. In this way, the projection scale corresponding to projecting the visible region 101 of the steering wheel to the cluster display surface 300 can be determined based on the first distance and the second distance.
The projection scale may be a ratio of the first distance to the second distance, or the projection scale may be further determined by calculation based on a ratio of the first distance to the second distance, which is not limited in the present invention.

For example, as shown in fig. 2, the center eye point 201 corresponding to the left eye ellipse may be taken as a projection point, and the visible area 101 of the steering wheel may be projected onto the cluster display surface 300 according to the projection scaling, to obtain the center field of view area 301.
In one implementation, one sub-center field of view region may be determined based on the center eyepoint simulation data corresponding to the left eye ellipse and the center eyepoint simulation data corresponding to the right eye ellipse, respectively, and then a union of the two sub-center field of view regions may be determined as the center field of view region.
For convenience of description, the center-eye point simulation data corresponding to the left-eye ellipse is referred to herein as first center-eye point simulation data, and the center-eye point simulation data corresponding to the right-eye ellipse is referred to herein as second center-eye point simulation data.
Illustratively, as shown in fig. 6, the visual area 101 of the steering wheel is projected to the cluster display surface 300 based on the first center eyepoint simulation data and the projection scale, resulting in a first sub-center visual field area 3011. And based on the second central eyepoint simulation data and the projection scaling, projecting the visible area of the steering wheel to the display surface of the combined instrument to obtain a second sub-central visual field area 3012. Finally, the union of the first sub-center visual field area 3011 and the second sub-center visual field area 3012 is determined as the center visual field area 301.
In summary, the method for obtaining the central field of view 301 provided by the present invention may determine the visual area 101 of the steering wheel on the steering plane 102, and then project the visual area 101 of the steering wheel to the combined instrument display surface 300 by means of equal scaling, so as to obtain the central field of view 301 on the combined instrument display surface 300, thus, complex calculation is not required, and the method is simple.
Fig. 7 is a flowchart of another embodiment of a method for determining a display area of a cluster meter according to the present invention, and in conjunction with fig. 1, as shown in fig. 7, step 130 in fig. 1 may specifically include the following steps 1301-1303.
Step 1301: a reference intersection is determined based on the center eyepoint simulation data and the first feature point simulation data.
The first characteristic point simulation data may be point simulation data of any point on the steering wheel 100. For example, the first characteristic point simulation data may be point simulation data located between an inner tangential plane and an outer tangential plane of the steering wheel 100.
In one implementation, a central field of view line may be established based on the central eyepoint simulation data and the first feature point simulation data; then, a reference intersection is determined based on the central visual field line and the combination meter display surface.
Illustratively, as shown in FIG. 8, a central line of sight L is established through the central eyepoint 201 and the first feature point 103 1 Center visual field line L 1 The extending part intersects with the display surface of the combined instrument at a point which is a reference intersection point A.
The center eyepoint 201 is an eyepoint position corresponding to the center eyepoint simulation data, and the first feature point 103 is a feature point position corresponding to the first feature point simulation data.
Step 1302: at least one limit intersection is determined based on the first feature point simulation data and the at least one limit eyepoint simulation data, respectively.
Similarly, determining at least one limit intersection may be performed in the following manner: at least one limiting view line can be established based on the first feature point simulation data and the at least one limiting eyepoint simulation data; then, at least one limit intersection is determined based on the at least one limit view line and the combination meter display surface, respectively.
Illustratively, the limit eyepoint simulation data includes upper limit eyepoint simulation data, lower limit eyepoint simulation data, left limit eyepoint simulation data, right limit eyepoint simulation data. As shown in fig. 8, an upper limit visual field line L is established by the upper limit eye point 202 and the first feature point 103 2 Upper limit visual field line L 2 The extended display surface intersects the meter display surface 300 at a point which is the upper limit intersection B. A lower limit visual field line L is established by the lower limit eyepoint 203 and the first feature point 103 3 Lower limit visual field line L 3 The extended display surface intersects the meter display surface 300 at a point which is the lower limit intersection C.
Fig. 9 is a top view of fig. 8, and as shown in fig. 9, a left limiting visual field line L is established by the left limiting eyepoint 204 and the first feature point 103 4 Left limit visual field line L 4 The extended display surface intersects the combination meter display surface 300 at a point which is the left limit intersection point D. A left limit visual field line L is established by the right limit eyepoint 205 and the first feature point 103 5 Right limit line of sight L 5 The extended display surface intersects with the display surface 300 of the combination meter at a point which is a right limit intersection point E.
The reference intersection a, the upper limit intersection B, the lower limit intersection C, the left limit intersection D, and the right limit intersection E, which are formed by intersecting the combination meter display surface 300, are all located on the combination meter display surface 300.
Step 1303: and taking the reference intersection point A as a locating point, and translating the central visual field area 301 based on the reference intersection point A and each limit intersection point to obtain a limit visual field area corresponding to each limit intersection point.
Here, the central visual field area 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, that is, the central visual field area 301 corresponds to the reference intersection point a. Based on such correspondence, the limit visual field region corresponding to each limit intersection can be obtained as follows.
In one implementation, the translation may be performed with the reference intersection point a and the central field of view area 301 as a whole, and specifically, the reference intersection point a is used as a positioning point during the translation. For example, the reference intersection point a is positioned to the upper limit intersection point B, and then the center visual field area 301 is correspondingly shifted while the reference intersection point a is moved to the upper limit intersection point B, so that the upper limit visual field area 302 corresponding to the upper limit intersection point B is obtained. Similarly, the reference intersection point a is positioned to the lower limit intersection point C, and then the center visual field area 301 is correspondingly shifted while the reference intersection point a is moved to the lower limit intersection point C, so that the lower limit visual field area 303 corresponding to the lower limit intersection point C is obtained. By the same method, a left limited field of view 304 and a right limited field of view 305 may be obtained, which will not be described in detail herein.
In one implementation, the distance between the reference intersection point a and each limit intersection point may also be determined first; then, the center field of view region 301 is shifted by the corresponding distance, respectively, to obtain the corresponding limited field of view region. For example, the distance between the reference intersection a and the upper limit intersection B is S1, and thus the upper limit visual field 302 is obtained by shifting the center visual field upward by the distance S1. By the same method, the lower limit view region 303, the left limit view region 304, and the right limit view region 305 can be obtained, and will not be described here.
In summary, according to the method for obtaining the limited view field area provided by the invention, the intersection points corresponding to the central eye point and the limited eye point are determined on the display surface of the combination instrument, and then the limited view field area corresponding to each limited eye point is obtained by translating the central view field area based on the corresponding relation between the central eye point and the central view field area. Therefore, each limited visual field area can be determined only by translating the central visual field area, the method is simple, and complex calculation is not needed.
Fig. 10 is a flowchart of another embodiment of a method for determining a display area of a cluster, which may further correct the display area of the cluster determined in step 140. As shown in fig. 10, the method for determining the display area of the cluster may further include the following steps 150 to 180 in addition to the steps 110 to 140.
Step 150: upper boundary point simulation data of the airbag are acquired.
For a vehicle equipped with an airbag, the airbag is generally disposed between the steering wheel and the combination meter display surface, and near the underside of the steering wheel.
Illustratively, as shown in fig. 5, the airbag 400 is located between the steering wheel 100 and the cluster display surface 300, and a user can see a partial area of the airbag 400 through the visible area 101 of the steering wheel. In this way, the airbag 400 may also cause a certain shielding for the user to view the combination meter, so the display area of the combination meter determined in step 140 is further modified in the present invention, so as to eliminate the influence of the airbag 400 on the user to view the combination meter.
As shown in fig. 11, the upper boundary point 401 of the airbag refers to a point tangent to the upper boundary of the airbag 400 through the lower limit eyepoint 203.
Step 160: a first correction intersection is determined based on the second feature point simulation data and the upper limit eyepoint simulation data.
As shown in fig. 11, the second feature point 104 may be any point located on an inner tangential plane or an inscribed line of the steering wheel 100.
In one implementation, the first correction intersection point is determined by: as shown in fig. 11, an upper visual field line L is established based on the second feature point simulation data and the upper limit eyepoint simulation data 6 The method comprises the steps of carrying out a first treatment on the surface of the Then, an upper visual field line L 6 The extended display surface intersects the combination meter display surface 300 at a point which is the first correction intersection F.
Wherein the first correction intersection F is located on the cluster display surface 300.
It should be noted that, the method for obtaining the limited field of view provided in the present invention may be combined with the embodiment of step 130 shown in fig. 7. Correspondingly, the first feature point 103 may be any point located between the inner tangential surface and the outer tangential surface of the steering wheel 100, for example, the first feature point 103 is a center point located between the inner tangential surface and the outer tangential surface of the steering wheel 100. The first feature point 103 and the second feature point 104 may be located on the same radius of the steering wheel 100 or on an extension line of the same radius.
In this way, when the first feature point 103 is located between the inner tangential plane and the outer tangential plane of the steering wheel 100, the second feature point 104 is located on the inner tangential plane or the inner tangential plane 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 same radius extension line of the steering wheel 100, the display area of the combination meter may be determined by using the method shown in fig. 7, and then the display area of the combination meter may be further corrected by using steps 150 to 180 to determine the display area of the combination meter in step 140, so that the display area of the combination meter after correction may be more accurate.
Step 170: a second correction intersection is determined based on the upper boundary point simulation data and the lower limit eyepoint simulation data of the airbag.
In one implementation, the second correction intersection point is determined by: as shown in fig. 11, a lower visual field line L is established based on the upper boundary point simulation data and the lower limit eyepoint simulation data of the airbag 7 The method comprises the steps of carrying out a first treatment on the surface of the Then, an upper visual field line L 7 The extended display surface intersects the combination meter display surface 300 at a point which is the second correction intersection point G.
Wherein the second correction intersection G is located on the cluster display surface 300.
Step 180: the display area of the combination meter is corrected based on the first correction intersection F and the second correction intersection G.
As shown in fig. 12, based on the above step 160, a first corrected intersection F is obtained above the display area 306 of the cluster. Based on the above step 170, a second corrected intersection G is obtained below the display area 306 of the cluster.
In one implementation, based on the first correction intersection F and the second correction intersection G, the display area 306 of the cluster is corrected in the following manner:
firstly, translating a display area 306 of the combination instrument based on a first correction intersection F to obtain a first display area; the upper edge of the first display area intersects the first correction intersection F.
Illustratively, as shown in fig. 13, the display area 306 of the cluster is translated upward along the Y-axis until the upper edge of the display area 306 of the cluster intersects the first correction intersection F, resulting in a first display area 3061.
Adopting a similar method, and translating a display area of the combination instrument based on the second correction intersection G to obtain a second display area;
illustratively, as shown in fig. 13, the display area 306 of the cluster is translated downward along the Y-axis until the lower edge of the display area 306 of the cluster intersects the second correction intersection G, resulting in a second display area 3062.
Finally, the union of the first display area 3061, the second display area 3062, and the display area 306 of the combination meter before correction is determined as the display area of the combination meter after correction.
In summary, according to the method for determining the display area of the combination instrument provided by the invention, the upper boundary point simulation data and the second characteristic point simulation data of the safety air bag are introduced to correct the display area of the combination instrument, so that the display area of the combination instrument after correction is more accurate.
