The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The embodiment of the invention provides a display screen arrangement method which can well solve the problem that the imaging of a suspension type display screen affects driving safety. In the development and design process of the automobile, after the modeling exterior hard points (such as front windshield positions, steering wheel positions and the like) and the driver human body hard points are determined, according to the position relation of the modeling exterior hard points and the driver human body hard points, a light path reversible thought is adopted, the eye ellipse limiting position is taken as a starting point, a light propagation path is constructed through the upper boundary of a first visual area by reflection of the front windshield, and meanwhile, the visual area of the steering wheel and the operating space requirement of the steering wheel hand are combined, so that the target area of the display screen arrangement meeting the man-machine requirement can be rapidly determined.
With reference to the flowchart shown in fig. 1, the present embodiment provides a display screen arrangement method, which specifically may include steps 101 to 102:
step 101: acquiring the position of a front windshield of a vehicle, the position of a steering wheel and the hard spot of a human body of a driver;
in this embodiment, in developing a design of a vehicle, regarding the display screen position arrangement, it is necessary to consider the problem that the display screen light is reflected by the front windshield. Therefore, the position of the front windshield needs to be considered when the display screen is arranged. In addition, it is also necessary to combine the steering wheel position with the hard spot of the driver's body. These data may be used as input conditions when the display is arranged.
Wherein the position of the front windshield and the position of the steering wheel are already determined when the display arrangement is considered. The driver in step 101 and the driver described in fig. 2 and 3 is then a manikin for the display screen arrangement. The hard points of the human body, which are hard points of the human body size, are determined by the human body model, and in this embodiment, mainly refer to the pedal points, heel points, and crotch points (i.e., H points).
Step 102: determining a target area for display screen arrangement according to the position of the front windshield, the position of the steering wheel and the hard point of the human body of the driver; when the display screen is arranged in the target area, the reflected light rays of the display screen passing through the front windshield cannot fall into the field of view of a driver.
After the position of the front windshield, the position of the steering wheel and the hard spot of the human body of the driver are obtained, the area where the display screen is arranged can be restricted according to the data, and the area for arranging the display screen, namely the target area, is defined.
A display screen disposed within the target area, the location of the display screen not interfering with steering wheel operation, as steering wheel position is taken into account during the placement process. Meanwhile, even if the light rays of the display screen are reflected by the front windshield, the light rays can not enter eyes of a driver, and the driver can not generate a dazzling problem.
In an alternative embodiment, the step of determining the target area of the display screen arrangement may comprise:
determining an eye ellipse of the driver according to the hard points of the human body of the driver and the position of the steering wheel;
determining a first visual area on the front windshield according to the position of the front windshield and the eye ellipse of the driver;
determining a steering wheel visible area according to the position of the steering wheel and the eye ellipse of the driver;
a target area for the display screen arrangement is determined from the first viewing zone, the steering wheel viewing zone and the driver's eye ellipse.
In this case, considering that drivers have different sizes in reality, different drivers sit on the driving seat in a normal driving posture, and their eye positions are obviously different. By studying the viewpoint distribution law of the driver by using statistical viewpoints and methods, it is found that the viewpoint distribution pattern of the driver of the vehicle is elliptical, that is, eye ellipse (Eye ellipse).
An eye ellipse is a statistical representation of the "driver's eye position" and there is no particular clear correspondence between height and eye position. In addition, the inclination angles of the male and female eye ellipses are not necessarily the same in statistical sense, and the male and female eye ellipses are not necessarily consistent with the same normal distribution, and the male and female eye ellipses are required to be respectively processed to obtain the male and female eye ellipses. However, for the convenience of engineering use, eye ellipses are often treated by a mixed eye spot method for men and women.
And the location of the eye ellipse is limited by the hard spot of the body and the steering wheel location. Thus, after determining the hard spot of the body and the position of the steering wheel, the driver's eye ellipse can be determined based on the contents of the SAEJ941 standard. Specifically, the pedal, heel and crotch points (also called H points) of the driver can be determined from the hard points of the human body; based on the SAEj941 criteria, the driver's eye ellipse is determined based on the pedal, heel, crotch points, and steering wheel positions of the driver.
In addition, as shown in fig. 3, after the eye ellipse of the driver is determined, the first viewing area and the driver's core viewing area on the front windshield may be further determined according to the position of the front windshield. The core visual area is located inside the first visual area. The first view area is a view area for a driver to observe the front road condition through the front windshield, and the core view area is a main view area for the driver to observe the front road condition. The specific determination method of the first view region and the driver's core visual field region may refer to the relevant contents in GB 11555. The present embodiment is mainly constrained by the first viewing zone, and more precisely, by the upper boundary of the first viewing zone when considering the display screen arrangement.
By combining the steering wheel position with the eye ellipse, the steering wheel viewable area can be determined, as shown in fig. 3. The steering wheel mainly comprises a peripheral skeleton and a central hub. The peripheral armature has a thickness because it may be referred to as the upper steering wheel rim adjacent the outer ring layer and may be referred to as the lower steering wheel rim adjacent the inner ring layer. While the center hub upper boundary may be referred to as the center hub upper boundary in conjunction with the two-dimensional schematic diagram shown in fig. 3, the boundary of the center hub near the roof.
In an alternative embodiment, the step of determining the visual area of the steering wheel based on the position of the steering wheel and the driver's eye ellipse may comprise:
determining the lower boundary of the upper rim of the steering wheel and the upper boundary of the central hub according to the position of the steering wheel;
the steering wheel visible region is defined based on the upper rim lower boundary of the steering wheel, the center hub upper boundary, and the driver's eye ellipse.
Wherein the position of the steering wheel is determined before the display screen is arranged. In this embodiment, referring to the schematic diagram of fig. 2, the lower boundary of the upper rim of the steering wheel refers to the boundary of the upper portion of the outer wheel skeleton of the steering wheel, which is located at the inner ring layer. A first tangent line is drawn from the lower boundary of the upper rim of the steering wheel to the upper portion of the eye ellipse.
The center hub upper boundary refers to the steering wheel center hub upper boundary. A second tangent line is drawn from the upper boundary of the central hub to the lower portion of the eye ellipse. The area limited by the first tangent line and the second tangent line is the visual area of the steering wheel. The object located in the visual area of the steering wheel can be seen from all places in the visual area of the steering wheel, and the sight is not blocked by the steering wheel when the object is observed from the position of the eye ellipse.
After defining the visual area of the steering wheel, the target area for display screen arrangement can be determined according to the visual area of the steering wheel, the first visual area and the eye ellipse of the driver, and the specific steps include:
determining an upper boundary of the first view region;
determining a lower limit light propagation path of the eye ellipse according to the upper boundary of the first visual zone and the eye ellipse of the driver;
the target area for the display screen arrangement is determined by defining the steering wheel viewable area based on the lower limit ray propagation path of the eye ellipse.
In this embodiment, the first viewing zone is located at the front windshield. After the current windshield position, the steering wheel position and the hard spot of the human body are determined, the first visual area can be determined, and reference is made to the two-dimensional schematic diagram of fig. 2. The boundary near the roof serves as the upper boundary of the first visual area, and the boundary near the front hood serves as the lower boundary of the first visual area.
And then, using the front windshield as a reflecting surface to form a reflection tangent of the third tangent. The third tangent line and the reflection tangent line form a lower limit light propagation path of the eye ellipse and the first visual area. It will be appreciated that the reflection tangent line is equivalent to splitting the visible area of the steering wheel, and further, the target area can be defined according to the operation boundary of the steering wheel, so as to finally obtain the target area.
Specifically, as shown in fig. 2, if a light source is provided in a shadow area near the right side of the reflection tangent to the steering wheel, the light reflected by the front windshield does not reach the eye ellipse.
Accordingly, in the region of the steering wheel visible region to the left of the reflection tangent, if there is a light source in this region, it is possible for light reflected by the front windshield to reach into the eye ellipse. The oval eyes are the possible positions of the driver's eyes, and if the display screen is arranged in the area, the light generated by the display screen may enter the eyes of the driver after being reflected by the front windshield, so that the driver is dazzled. The shaded area in fig. 2 is thus the target area, i.e. the area of the direction viewing zone is delimited based on the lower limit ray propagation path of the eye ellipse, and the resulting target area for the display screen arrangement is determined.
From the foregoing, it can be seen that, after the display screen is disposed in the target area, the light generated by the display screen is reflected by the front windshield, which does not cause glare to the driver, and repeated adjustment during post engineering and shaping can be avoided, thereby shortening the vehicle development period. Although the target area solves the display screen glare problem, the exact proper position is not yet given in the end. Based on this, in this embodiment, from the view point of optimal imaging of the display screen, the position of the display screen in the target area is further adjusted by using the preset viewing distance and the preset viewing angle, and the adjusting step may include:
determining a first center point of the eye ellipse and a second center point of the display screen;
according to the preset viewing distance, adjusting the distance from the first center point to the second center point;
and adjusting the angle between the connecting line of the first center point and the second center point and the display screen according to the preset visual angle.
Wherein, in connection with the illustration of fig. 4, the center points mentioned in the steps are all referenced to a two-dimensional schematic. The first center point refers to the center position of the eye ellipse and 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, and in this embodiment, the preset viewing distance may be set in a range of 380mm-760 mm. The viewing distance refers to the distance from the eye point to the display screen, and in this embodiment, may 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 eyepoint to the second center point of the display screen and the display screen. In this embodiment, the preset viewing angle may be set in the range of 90 ° ± 10 °. When the visual distance of the display screen is adjusted, comparing the distance from the first center point to the second center point with the preset visual distance, and if the distance from the first center point to the second center point is larger than the preset visual distance, moving the display screen towards the direction of the driver so that the distance from the first center point to the second center point is close to the preset visual distance. If the distance from the first center point to the second center point is smaller than the preset viewing distance, the display screen is moved towards the direction away from the driver, so that the distance from the first center point to the second center point is close to the preset viewing distance. When the viewing angle of the display screen is adjusted, referring to fig. 4, the angle between the connection line of the first center point and the second center point and the display screen is set as the viewing angle of the display screen, the viewing angle of the display screen is compared with the preset viewing angle, and if the viewing angle of the display screen is larger than the preset viewing angle, the display screen is rotated clockwise around the direction vertical to the plane of fig. 4 until the viewing angle of the display screen is equal to the preset viewing angle. If the viewing angle of the display screen is smaller than the preset viewing angle, the display screen is rotated anticlockwise around the direction perpendicular to the plane of fig. 4 until the viewing angle of the display screen is equal to the preset viewing angle.
The distance between the adjusted display screen and the center point of the eye ellipse is equal to the preset viewing distance, and the angle between the display screen and the connecting line of the first center point and the second center point is equal to the preset viewing angle. The display screen is wholly in the most suitable position that the driver observed, and the driver when driving the vehicle, the light of display screen can not cause the influence of dazzling to the driver, and distance is moderate, the angle is suitable simultaneously, is favorable to promoting driving experience.
