All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] This invention provides a display screen arrangement method that effectively solves the problem of floating display screen imaging affecting driving safety. During the automotive development and design process, once the hard points of the exterior styling (e.g., the windshield position, steering wheel position, etc.) and the driver's human body hard points are determined, based on their positional relationship, and using a reversible optical path approach, starting from the eye ellipse limit position, passing through the upper boundary of the first visual area, and reflecting off the windshield, a light propagation path is constructed. Simultaneously, by combining the visible area of ​​the steering wheel and the hand operation space requirements, the target area for display screen arrangement that meets human-machine interface requirements can be quickly determined.

[0051] Combination Figure 1 The flowchart shown illustrates a display screen arrangement method provided in this embodiment, which may specifically include steps 101 to 102:

[0052] Step 101: Obtain the position of the vehicle's windshield, steering wheel, and the driver's hard points;

[0053] In this embodiment, when developing and designing the vehicle, the placement of the display screen needs to consider the reflection of light from the windshield. Therefore, this solution requires taking the windshield position into account when arranging the display screen. Additionally, the steering wheel position and the driver's hard points also need to be considered. These data can be used as input conditions when arranging the display screen.

[0054] In this case, the positions of the windshield and steering wheel have already been determined when considering the layout of the display screen. The driver in step 101 and... Figure 2 , Figure 3 The driver is a human body model used for display screen placement. The human body model can be used to determine the hard points of the human body, which refer to the hard points of human body size. In this embodiment, these mainly refer to the foot pedal point, heel point, and hip point (i.e., H point).

[0055] Step 102: Determine the target area for the display screen based on the position of the windshield, the position of the steering wheel, and the driver's hard points; wherein, when the display screen is placed in the target area, the light reflected from the windshield will not fall into the driver's field of vision.

[0056] After obtaining the position of the windshield, the position of the steering wheel, and the driver's hard points, the area for arranging the display screen can be constrained based on the above data, thus defining the area for arranging the display screen, which is the target area.

[0057] The display screens, positioned within the target area, are designed with the steering wheel location in mind, ensuring their placement does not obstruct steering wheel operation. Furthermore, even after reflection from the windshield, the screen's light will not enter the driver's eyes, preventing glare.

[0058] In one alternative implementation, the step of determining the target area for the display screen arrangement may include:

[0059] Determine the driver's eye ellipse based on the driver's hard points and the position of the steering wheel;

[0060] Determine the first visual zone on the windshield based on the position of the windshield and the ellipse of the driver's eye;

[0061] Determine the visible area of ​​the steering wheel based on its position and the driver's eye ellipse.

[0062] The target area for display screen placement is determined based on the first viewing area, the steering wheel viewing area, and the driver's eye ellipse.

[0063] In practice, considering the varying sizes of drivers and the different eye positions they occupy when seated in a normal driving posture, a statistical study of driver gaze distribution revealed that the gaze distribution pattern of vehicle drivers is elliptical, also known as the eye ellipse.

[0064] The eye ellipse is a statistical representation of "driver's eye position," and there is no particularly clear correlation between height and eye position. Furthermore, statistically speaking, the inclination angle of the eye ellipse is not necessarily the same for men and women, nor does it necessarily follow the same normal distribution. Therefore, the eye ellipses for men and women should be processed separately to obtain male and female eye ellipses. However, for engineering convenience, a mixed approach is often used to process the eye ellipse based on male and female eye points.

[0065] The position of the eye ellipse is limited by the hard points of the human body and the position of the steering wheel. Therefore, after determining the hard points of the human body and the position of the steering wheel, the driver's eye ellipse can be determined based on the content of the SAE J941 standard. Specifically, the driver's pedal point, heel point, and hip point (also called H point) can be determined based on the hard points of the human body; and the driver's eye ellipse can be determined based on the SAE J941 standard using the pedal point, heel point, hip point, and steering wheel position.

[0066] In addition, combined Figure 3As shown, after determining the driver's eye ellipse, the first viewing area and the driver's core field of vision on the windshield can be further determined based on the position of the windshield. The core field of vision is located within the first viewing area. The first viewing area is the area through which the driver observes the road conditions ahead through the windshield, while the core field of vision is the driver's primary field of vision for observing the road conditions ahead. Specific methods for determining the first viewing area and the driver's core field of vision can be found in the relevant content of GB11555. In this embodiment, when considering the display screen arrangement, the first viewing area is mainly used as a constraint; more precisely, the upper boundary of the first viewing area is used for constraint.

[0067] By combining the position of the steering wheel with the ellipse of the eye, the visible area of ​​the steering wheel can be determined, such as... Figure 3 As shown. The steering wheel mainly consists of an outer frame and a central hub. The outer frame has a certain thickness; the part closer to the outer ring can be called the upper rim of the steering wheel, and the part closer to the inner ring can be called the lower rim. The upper boundary of the central hub can be combined with... Figure 3 The two-dimensional schematic diagram shown refers to the boundary of the center hub near the roof as the upper boundary of the center hub.

[0068] In one alternative implementation, the step of determining the visible area of ​​the steering wheel based on the steering wheel position and the driver's eye ellipse may include:

[0069] Determine the lower boundary of the upper rim of the steering wheel and the upper boundary of the center hub based on the position of the steering wheel;

[0070] The visible area of ​​the steering wheel is defined by the lower boundary of the upper rim of the steering wheel, the upper boundary of the center hub, and the ellipse of the driver's eye.

[0071] In this embodiment, the position of the steering wheel is determined before the display screen is arranged. Figure 2 For reference, the lower boundary of the steering wheel rim refers to the boundary of the upper part of the steering wheel outer frame located in the inner ring layer. Draw the first tangent line from the lower boundary of the steering wheel rim to the upper part of the eye ellipse.

[0072] The upper boundary of the center hub refers to the upper edge of the center hub of the steering wheel. Draw a second tangent from the upper boundary of the center hub towards the lower part of the eye ellipse. The area defined by the first tangent and the second tangent is the visible area of ​​the steering wheel. Objects within the visible area of ​​the steering wheel, viewed from the position of the eye ellipse, will not have their line of sight obstructed by the steering wheel; all areas within the visible area can be seen.

[0073] After defining the visible area of ​​the steering wheel, the target area for the display screen can be determined based on the visible area of ​​the steering wheel, the first visual zone, and the driver's eye ellipse. The specific steps include:

[0074] Determine the upper boundary of the first field of view;

[0075] Based on the upper boundary of the first visual zone and the driver's eye ellipse, determine the lower limit of the light propagation path of the eye ellipse;

[0076] Based on the lower limit of the light propagation path of the eye ellipse, the visible area of ​​the steering wheel is defined, and the target area for the display screen is determined.

[0077] In this embodiment, the first viewing area is located at the windshield. Once the position of the windshield, the position of the steering wheel, and the hard points of the human body are determined, the first viewing area can be determined, as shown in the reference... Figure 2 A two-dimensional schematic diagram. The boundary near the roof is the upper boundary of the first field of view, and the boundary near the hood is the lower boundary of the first field of view.

[0078] Draw a third tangent from the upper boundary of the first visual zone to the lower part of the eye ellipse. Then, using the windshield as a reflective surface, draw the reflection tangent of this third tangent. The third tangent and the reflection tangent constitute the light propagation path of the lower limit of the eye ellipse and the first visual zone. It is easy to understand that the reflection tangent is equivalent to dividing the visible area of ​​the steering wheel. Furthermore, the target area can be defined based on the steering wheel operation boundary, thus obtaining the final target area.

[0079] Specifically, combining Figure 2 As shown, in the shadow area near the steering wheel to the right of the reflection tangent, if there is a light source in this area, the light reflected from the windshield will not reach the eye ellipse.

[0080] Correspondingly, in the steering wheel's visible area to the left of the reflection tangent, if there is a light source in that area, the light reflected through the windshield may reach the eye ellipse. The eye ellipse represents the possible location of the driver's eye point; if the display screen is placed in this area, the light emitted by the screen, reflected by the windshield, may enter the driver's eyes, causing glare. Therefore, Figure 2 The shadowed area in the image is the target area, which is defined by the lower limit of the light propagation path of the eye ellipse to define the visible area of ​​the steering wheel and determine the target area for the display screen.

[0081] As described above, once the display screen is positioned in the target area, the light emitted by the screen will not cause glare to the driver after being reflected by the windshield. This avoids repeated adjustments during later engineering and design phases, thereby shortening the vehicle development cycle. Although the target area solves the glare problem, a precise and suitable location has not yet been determined. Therefore, this embodiment considers the optimal imaging angle of the display screen and uses preset viewing distances and preset viewing angles to further adjust the position of the display screen in the target area. The adjustment steps may include:

[0082] Determine the first center point of the eye ellipse and the second center point of the display screen;

[0083] Adjust the distance between the first center point and the second center point according to the preset viewing distance;

[0084] Adjust the angle between the line connecting the first center point and the second center point and the display screen according to the preset viewing angle.

[0085] Among them, combined Figure 4 As shown, the center points mentioned in the steps are all references to the two-dimensional schematic diagram. The first center point refers to the center position of the eye ellipse, which can be used as a reference eye point. The second center point refers to the center position of the display screen. The preset viewing distance is a preset viewing distance value. In this embodiment, the preset viewing distance can be set in the range of 380mm-760mm. Viewing distance refers to the distance from the eye point to the display screen. In this embodiment, it can be considered as the distance from the first center point to the second center point, that is, the length of the line connecting the first center point and the second center point. The preset viewing angle is a preset angle value. The viewing angle refers to the angle between the line connecting the eye point to the second center point of the display screen and the display screen. In this embodiment, the preset viewing angle can be set in the range of 90°±10°. When adjusting the display screen viewing distance, the distance from the first center point to the second center point is compared with the preset viewing distance. If the distance from the first center point to the second center point is greater than the preset viewing distance, the display screen is moved towards the driver to make the distance from the first center point to the second center point closer to the preset viewing distance. If the distance from the first center point to the second center point is less than the preset viewing distance, the display screen is moved away from the driver to make the distance from the first center point to the second center point closer to the preset viewing distance. When adjusting the screen viewing angle, refer to Figure 4 The angle between the line connecting the first center point and the second center point and the display screen is set as the display screen viewing angle. The display screen viewing angle is compared with the preset viewing angle. If the display screen viewing angle is greater than the preset viewing angle, the display screen is rotated around a line perpendicular to the center point. Figure 4 Rotate the screen clockwise until the viewing angle matches the preset viewing angle. If the viewing angle is smaller than the preset viewing angle, rotate the screen around a direction perpendicular to the plane. Figure 4 Rotate counterclockwise in the plane until the screen viewing angle is equal to the preset viewing angle.

[0086] The adjusted display screen is positioned so that its distance from the center of the eye ellipse is equal to the preset viewing distance, and the angle between the display screen and the line connecting the first and second center points is equal to the preset viewing angle. The display screen is positioned at the most suitable observation point for the driver. When the driver is driving, the light from the display screen will not cause glare, and the appropriate distance and angle will enhance the driving experience.

[0087] In summary, the display screen arrangement device provided in this specification obtains the position of the vehicle's windshield, the position of the steering wheel, and the driver's hard point; based on these factors, a target area for display screen arrangement is determined; wherein, when the display screen is arranged within the target area, the light reflected from the windshield will not fall into the driver's field of vision. Thus, the problem of driver glare caused by reflected light from the display screen on the windshield can be avoided in the early design stages, improving driving safety, shortening the vehicle development cycle, and saving design change costs.
