[0036] The implementation details of the technical solutions of the embodiments of the present application are elaborated in detail below:

[0037] First of all, it should be noted that the method for arranging the side windshield air outlets proposed in this application can be applied to the technical field of arranging side windshield defrosting and defogging air outlets of vehicles. For example, when the temperature difference between the inside and outside of the vehicle is large in winter, the side windshield glass of the vehicle often frosts and fogs, which affects the driver's ability to confirm the driving environment outside the vehicle by observing the outside rearview mirror. The current arrangement of side windshield defrosting and defogging air outlets cannot quickly defrost and defog the target side windshield area, seriously affecting the driving safety of the driver. Therefore, the accurate arrangement of the side windshield air outlets of the vehicle is particularly important.

[0038] According to one aspect of the embodiments of the present application, a method for arranging side windshield air outlets of a vehicle is provided. Figure 1 FIG. is a flowchart of a method for arranging side windshield air outlets of a vehicle shown according to an embodiment of the present application. Figure 6Schematic diagram of an automotive side windshield shown according to an embodiment of the present application. The method for arranging the air outlets of the automotive side windshield can be executed by a device with computing and processing capabilities. The method for arranging the air outlets of the automotive side windshield at least includes steps 110 to 150, which are introduced in detail as follows:

[0039] Please refer to Figure 1 and Figure 6 In step 110, at least one eye point region 20 is determined for the target driving population in the automotive three-dimensional coordinate system.

[0040] It should be emphasized that the automotive three-dimensional coordinate system is established based on the internationally common automotive coordinate system, with the midpoint of the front axle of the vehicle as the origin, the X-axis direction pointing to the rear of the vehicle, the Y-axis direction pointing to the co-pilot of the vehicle, and the Z-axis direction pointing to the roof of the vehicle.

[0041] In the present application, 5% to 95% of the population is taken as the target driving population, that is, people with extremely large differences in body shape characteristics are excluded, such as special people with a height of 2.5 meters. At least one eye point region 20 is determined in the automotive three-dimensional coordinate system, and the eye point region 20 is used to represent the eye position of the driver.

[0042] Please refer to Figure 7 , Figure 7 Schematic diagram of the target side windshield region shown according to an embodiment of the present application. In step 120, based on the relative position between the at least one eye point region 20 and any one automotive exterior rearview mirror 10, a target side windshield region 40 is determined on the automotive side windshield 30 corresponding to the any one automotive exterior rearview mirror 10.

[0043] In the present application, the light of the automotive exterior rearview mirror 10 enters the eye point region 20 through the corresponding target side windshield region 40. By connecting the automotive exterior rearview mirror 10 and the eye point region 20, the target side windshield region 40 can be determined on the automotive side windshield 30 corresponding to the automotive exterior rearview mirror 10.

[0044] In step 130, a first reference point is determined in the target side windshield region 40, and the first reference point serves as the air volume output point of the automotive side windshield air outlet.

[0045] In the present application, a first reference point is determined in the target side windshield region 40, and the first reference point serves as the air volume output point of the automotive side windshield air outlet. The air outlet of the automotive side windshield is relatively small with respect to the target side windshield region 40, and the air outlet of the automotive side windshield cannot directly blow to all regions of the target side windshield region 40 at the same time. By setting the first reference point, the air outlet of the automotive side windshield blows towards the first reference point, enabling the target side windshield region 40 to respond to the air volume of the automotive side windshield air outlet at the fastest speed, thereby quickly defrosting and defogging the target side windshield region 40.

[0046] Please refer toFigure 8 , Figure 8 It is a schematic diagram showing the layout range of the automotive side windshield air outlet according to an embodiment of the present application. In step 140, with the first reference point as the center of the sphere, a first spherical surface 50 and a second spherical surface 60 are respectively generated according to a first preset radius and a second preset radius, and the second preset radius is greater than the first preset radius.

[0047] In the present application, there is a minimum distance and a maximum distance between the automotive side windshield air outlet and the first reference point. With the first reference point as the center of the sphere, a first spherical surface 50 and a second spherical surface 60 are respectively generated according to a first preset radius and a second preset radius, and the layout range of the automotive side windshield air outlet is determined by the first spherical surface 50 and the second spherical surface 60. When the first reference point is in the target side windshield area 40 on the driver's side, the first preset radius can be 100 mm, and the second preset radius can be 300 mm. When the first reference point is in the target side windshield area 40 on the co-driver's side, the first preset radius can be 110 mm, and the second preset radius can be 380 mm.

[0048] In step 150, the automotive side windshield air outlet is arranged in the automotive interior area between the first spherical surface 50 and the second spherical surface 60.

[0049] In the present application, the layout range of the automotive side windshield air outlet is determined by the first spherical surface 50 and the second spherical surface 60, and the automotive side windshield air outlet needs to be in the automotive interior area, so that the layout position of the automotive side windshield air outlet can be confirmed.

[0050] In the present application, at least one eye point area 20 is determined for the target driving group in the automotive three-dimensional coordinate system, and the eye point area 20 is used to represent the position of the driver's eyes in the automotive three-dimensional coordinate system. The light of the outside rearview mirror needs to pass through the target side windshield area 40 to reach the eye point area 20. With the eye point area 20 and the outside rearview mirror, the target side windshield area 40 on the side windshield corresponding to the outside rearview mirror can be determined. The first reference point is determined based on the target side windshield area 40, the first reference point is used as the air volume output point of the automotive side windshield air outlet, with the first reference point as the center of the sphere, a first spherical surface 50 and a second spherical surface 60 are respectively generated according to a first preset radius and a second preset radius, and the automotive side windshield air outlet is arranged in the automotive interior area between the first spherical surface 50 and the second spherical surface 60. The wind blown out by the side windshield defrosting and defogging air outlet can directly blow to the first reference point in the target side windshield area 40, quickly defrost and defog the target side windshield area 40, provide a good driving environment for the driver, and improve the driving safety of the driver for the vehicle.

[0051] In one embodiment of the present application, in step 120, based on the relative position of the at least one eye point region 20 and any one of the vehicle exterior rearview mirrors 10, a target side windshield region 40 is determined on the vehicle side windshield 30 corresponding to the any one of the vehicle exterior rearview mirrors 10, which can be performed according to as Figure 2 shown steps.

[0052] Please refer to Figure 2 and Figure 6 , which is a detailed flowchart showing the determination of the target side windshield region 40 on the vehicle side windshield 30 corresponding to the any one of the vehicle exterior rearview mirrors 10 based on the relative position of the at least one eye point region 20 and the any one of the vehicle exterior rearview mirrors 10 according to an embodiment of the present application. Specifically, it includes steps 121 to step 122:

[0053] Step 121, for each target eye point region 20, based on the relative position of the target eye point region 20 and any one of the vehicle exterior rearview mirrors 10, a side windshield region is determined on the vehicle side windshield 30 corresponding to the any one of the vehicle exterior rearview mirrors 10, and the target eye point region 20 is any one of the at least one eye point region 20.

[0054] Step 122, determine the union of the side windshield regions corresponding to each eye point region 20 to obtain the target side windshield region 40.

[0055] In the present application, multiple target eye point regions 20 can be set according to requirements, and each target eye point region 20 can determine a side windshield region on the side windshield with the vehicle exterior rearview mirror 10. By determining the union of the side windshield regions corresponding to each target eye point region 20 through multiple target eye point regions 20, the target side windshield region 40 is obtained.

[0056] In one embodiment of the present application, the determination of the side windshield region on the vehicle side windshield 30 corresponding to the any one of the vehicle exterior rearview mirrors 10 based on the relative position of the target eye point region 20 and the any one of the vehicle exterior rearview mirrors 10 can be performed according to as Figure 3 shown steps.

[0057] Please refer to Figure 3 and Figure 7 , which is a detailed flowchart showing the determination of the side windshield region on the vehicle side windshield 30 corresponding to the any one of the vehicle exterior rearview mirrors 10 based on the relative position of the target eye point region 20 and the any one of the vehicle exterior rearview mirrors 10 according to an embodiment of the present application. Specifically, it includes steps 1211 to step 1212:

[0058] Step 1211, generate a barrel-shaped surface based on the boundary of the target eye point region 20 and the boundary of any one of the vehicle exterior rearview mirrors 10.

[0059] Step 1212: Determine the area where the barrel-shaped surface intersects with the vehicle side window 30 corresponding to any one of the vehicle exterior rearview mirrors 10 as the side window area.

[0060] In the present application, the boundary of the target eye point area 20 and the boundary of any one of the vehicle exterior rearview mirrors 10 generate a barrel-shaped surface. The barrel-shaped surface intersects with the vehicle side window 30 corresponding to the vehicle exterior rearview mirror 10, and the intersecting area is determined as the side window area. The light of the vehicle exterior rearview mirror 10 enters the target eye point area 20 through the side window area. As long as there is no frost or fog in the side window area, the driver can directly view the exterior rearview mirror through the side window area, thereby observing the external driving environment of the vehicle.

[0061] In an embodiment of the present application, to determine the first reference point in the target side window area, the following steps can be performed as Figure 4 shown.

[0062] Please refer to Figure 4 , which is a detailed flowchart for determining the first reference point in the target side window area shown according to an embodiment of the present application, specifically including steps 131 to 135:

[0063] Step 131: Determine the boundary point with the largest coordinate value on the X-axis of the vehicle three-dimensional coordinate system in the target side window area as the first boundary point, determine the boundary point with the smallest coordinate value on the X-axis of the vehicle three-dimensional coordinate system in the target side window area as the second boundary point, determine the boundary point with the largest coordinate value on the Z-axis of the vehicle three-dimensional coordinate system in the target side window area as the third boundary point, and determine the boundary point with the smallest coordinate value on the Z-axis of the vehicle three-dimensional coordinate system in the target side window area as the fourth boundary point.

[0064] Step 132: Determine the line connecting the first boundary point and the second boundary point as the first line, and determine the line connecting the third boundary point and the fourth boundary point as the second line.

[0065] Step 133: Determine the coordinate value on the X-axis of the vehicle three-dimensional coordinate system at the 1 / 3 position close to the second boundary point on the first line as the X-axis coordinate, and determine the coordinate value on the Z-axis of the vehicle three-dimensional coordinate system at the midpoint position on the second line as the Z-axis coordinate.

[0066] Step 134: Determine the point defined by the X-axis coordinate and the Z-axis coordinate in the X-Z plane of the vehicle three-dimensional coordinate system as the second reference point.

[0067] Step 135: Determine the projection point of the second reference point in the Y-axis direction of the automotive three-dimensional coordinate system within the target side windshield area as the first reference point.

[0068] In this application, the target side windshield area consists of a set of side windshield areas obtained from multiple eye point areas and the automotive exterior rearview mirror on the corresponding side windshield. For the target side windshield area, the boundary point with the maximum coordinate value on the X-axis of the automotive three-dimensional coordinate system is taken as the first boundary point, and the boundary point with the minimum coordinate value on the X-axis of the automotive three-dimensional coordinate system is taken as the second boundary point. The connection between the first boundary point and the second boundary point is determined as the first connection line. Take the coordinate value on the X-axis at the 1 / 3 position close to the second boundary point on the first connection line as the X-axis coordinate. Similarly, for the target side windshield area, the boundary point with the maximum coordinate value on the Y-axis of the automotive three-dimensional coordinate system is taken as the third boundary point, and the boundary point with the minimum coordinate value on the Z-axis of the automotive three-dimensional coordinate system is taken as the fourth boundary point. The connection line between the third boundary point and the fourth boundary point is determined as the second connection line. Take the coordinate value on the Z-axis at the central position on the second connection line as the Z-axis coordinate. According to the X-axis coordinate and the Z-axis coordinate, determine any point defined by the X-axis coordinate and the Z-axis coordinate on the X-Z plane of the automotive three-dimensional coordinate system as the second reference point, and then take the projection point obtained by projecting the second reference point in the Y-axis direction of the automotive three-dimensional coordinate system onto the target side windshield area as the first reference point. The first reference point is within the target side windshield area and is at the 1 / 3 position of the first connection line close to the second boundary point. Since the conventional placement position of the side windshield defrosting and defogging air outlet is close to the second boundary point, after the air volume blown out by the side windshield defrosting and defogging air outlet blows towards the first reference point, it can quickly spread to the target side windshield area, improving the efficiency of the side windshield defrosting and defogging air outlet in dispersing the frost and fog in the target side windshield area.

[0069] In an embodiment of this application, at least one of the at least one eye point area 20 includes the SAE eye ellipse area 22.

[0070] Please refer to Figure 6 and Figure 7, in the present application, the eye point region 20 at least includes the SAE eye ellipse region 22. The SAE eye ellipse is a statistical representation of the driver's eye position by the Society of Automotive Engineers. In this embodiment, the projection of the SAE eye ellipse on the driver's neutral plane parallel to the X-Z plane is taken as the SAE eye ellipse region 22. After verification, the difference between the SAE eye ellipse and the target side windshield region 40 obtained from the SAE eye ellipse region 22 of the present application is very small, but the SAE eye ellipse region 22 is more convenient to operate. The SAE eye ellipse region 22 can represent the eye point range of the general population. At the same time, the eye point region 20 can also include the mid-eye points 21 of drivers at each percentile. The percentile represents the percentage of people with a certain body size and smaller than this size among the total number of statistical objects. Taking the 5th percentile and the human height size as an example, it means that 5% of people have a height equal to or less than this size. The SAE eye ellipse region 22 can represent the population from 5% to 95%. Together with the mid-eye points 21 of drivers at each percentile generated by Ramsis, the combination of the two makes the eye point region 20 more accurate and in line with the design of the Asian population. Before generating the barrel-shaped surface with the mid-eye points 21 of drivers at each percentile and the outside rearview mirror, first, with the mid-eye points 21 of drivers at each percentile as the center, make a circle Y01 with a radius of 2 mm on a plane parallel to the X-Z plane, and then generate the barrel-shaped surface with the circle Y01 and the outside rearview mirror. The barrel-shaped surface generated by the circle Y01 and the outside rearview mirror intersects with the corresponding side windshield to obtain the side windshield region. The mid-eye points 21 of drivers at each percentile include the mid-eye points of 5% female drivers, the mid-eye points of male drivers with a height of 2 meters, etc.

[0071] In an embodiment of the present application, the automotive side windshield air outlet is arranged in the automotive interior region between the first spherical surface 50 and the second spherical surface 60, and can be executed according to the steps as Figure 5 shown.

[0072] Please refer to Figure 5 and Figure 8 , which is a detailed flowchart showing the arrangement of the automotive side windshield air outlet in the automotive interior region between the first spherical surface 50 and the second spherical surface 60 according to an embodiment of the present application, specifically including steps 151 to 153, including:

[0073] Step 151, determine a first plane parallel to the X-Y plane in the automotive three-dimensional coordinate system, and the first plane is tangent to the lower boundary of the SAE eye ellipse region 22.

[0074] Step 152, translate the first plane downward by a preset distance along the Z-axis direction in the automotive three-dimensional coordinate system to obtain a second plane 70.

[0075] Step 153, arrange the vehicle side windshield air outlet in the vehicle interior area below the second plane 70 and between the first spherical surface 50 and the second spherical surface 60.

[0076] In this application, with the SAE circular ellipse area as the boundary, determine the first plane parallel to the X-Y plane in the vehicle three-dimensional coordinate system and tangent to the lowest boundary of the SAE circular ellipse area. Translate the first plane downward (in the opposite direction of the Z-axis direction) along the Z-axis direction in the vehicle three-dimensional coordinate system by a preset distance. The preset distance is 100 mm to obtain the second plane 70. Finally, arrange the vehicle side windshield air outlet in the vehicle interior area below the second plane 70 and between the first spherical surface 50 and the second spherical surface 60. Since the driver's eyes are higher than the height of the vehicle exterior rearview mirror 10, the height of the vehicle side windshield air outlet is lower than the driver's eye height by a certain distance, so as not to affect the driver's observation of the exterior rearview mirror and improve the driving safety of the driver.

[0077] In an embodiment of this application, arranging the vehicle side windshield air outlet in the vehicle interior area below the second plane 70 and between the first spherical surface 50 and the second spherical surface 60 includes: arranging the vehicle side windshield air outlet on the surface of the A-pillar or the door trim or the instrument panel in the vehicle interior area below the second plane 70 and between the first spherical surface 50 and the second spherical surface 60.

[0078] In this application, the vehicle side windshield air outlet needs to be arranged on the vehicle entity, fixed by being set on the surface of the A-pillar or the door trim or the instrument panel. At the same time, ensure that there is no object blocking between the vehicle side windshield air outlet and the first reference point, which can effectively improve the air volume blown out by the vehicle side windshield air outlet to achieve a good defrosting and defogging effect on the side windshield.

[0079] In summary, in this application, with the goal as the orientation, establish the eye point area in the vehicle three-dimensional coordinate system, determine the target side windshield area based on the eye point area and the vehicle exterior rearview mirror, determine the first reference point in the target side windshield area, and the vehicle side windshield air outlet should face the first reference point to achieve the best defrosting and defogging effect. With the first reference point as the target orientation, determine the range where the vehicle side windshield air outlet can be arranged, so as to determine the arrangement position of the vehicle side windshield air outlet. It improves the accuracy of the arrangement of the vehicle side windshield air outlet, improves the clearing effect of the vehicle side windshield air outlet on the frost and fog on the side windshield, and enhances the driving safety of the driver.
