Description

[0045] The method provided by the embodiment of the present application obtains the position information of the imaging interference area and the imaging display area on the window glass by acquiring the eye ellipse position information, the rearview mirror position information, and the center control screen position information, and considers the background brightness information and the imaging brightness information of the imaging display area of the window glass.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0047] Please refer to Figure 1 , which is a schematic flow chart of a method for adjusting a center control screen provided by an embodiment of the present application, and specifically may include:

[0048] S110. Obtain the position information of the imaging interference area on the window glass according to the eye ellipse position information, the rearview mirror position information, and the center control screen position information;

[0049] Exemplarily, as Figure 2 shown in the schematic diagram of the imaging principle of the center control screen on the window glass, when the driver needs to observe the road conditions information behind, the driver needs to observe the image behind the vehicle through the rearview mirror through the window glass. The center control screen of the vehicle will also form a projection on the window glass. When the projection of the center control screen on the window glass coincides with the window perspective area when the human eye observes the rearview mirror image, the projection of the center control screen is likely to affect the driver's observation of the image behind, bringing risks to the driver's driving behavior.

[0050] In an embodiment of the present application, by obtaining the eye ellipse position information, rearview mirror position information, and center console screen position information of the driver, the perspective area of the rearview mirror image on the window glass when the driver observes the rearview mirror is determined based on the above three position information, that is, the position information of the above imaging interference area. That is to say, when the projection area of the center console screen on the window glass overlaps with the imaging interference area, it may affect the normal driving of the driver.

[0051] It should be noted that the center console screen position information includes the position and angle of the center console screen, and the rearview mirror position information also includes the position and angle of the rearview mirror. The concept of the eye ellipse was proposed with the development of the engineering capabilities of the automotive industry. It was developed by automotive engineers to ensure that most automotive drivers have good vision characteristics. The eye ellipse refers to the statistical distribution pattern of the eye positions of occupants of different body sizes sitting in the vehicle in a normal posture. The specific determination method will not be elaborated here.

[0052] S120. Obtain the position information of the imaging display area on the above window glass based on the above eye ellipse position information and the above center console screen position information;

[0053] Exemplarily, the projection area of the image of the center console screen on the window glass is obtained through the eye ellipse position information and the position information of the center console screen, that is, the position information of the imaging display area.

[0054] S130. Obtain the background brightness information and imaging brightness information of the above window glass imaging display area;

[0055] Exemplarily, whether the projected image of the center console screen affects the driver's normal viewing of the rearview mirror is not only related to the display area position and the interference area position, but also related to the background brightness information (i.e., the window reflection brightness) and the imaging brightness information (i.e., the continuity of the screen projected on the window) in the imaging display area of the projected image. Therefore, in this embodiment, the background brightness and imaging brightness information of the window glass imaging display area are obtained to evaluate the influence of the brightness on the driver.

[0056] S140. Generate a center console screen control instruction through the above imaging interference area position information, the above imaging display area position information, the above background brightness information, and the above imaging brightness information;

[0057] Exemplarily, a center console screen control instruction is generated according to the above-obtained position information, imaging display area position information, background brightness information, and imaging brightness information. The above center console screen control instruction can comprehensively consider the projection position and projection image brightness intensity of the center console screen, and make adjustments to the center console screen in terms of position and brightness to reduce the influence of the center console screen projection on the driver's viewing of the rearview mirror. It can be understood that the control instruction can be a center console screen position and angle control instruction, or a center console screen brightness control instruction.

[0058] S150. Adjust the central control screen based on the above central control screen control instruction.

[0059] Exemplarily, control the position, angle, and brightness of the central control screen according to the generated central control screen control instruction above. It can be understood that the position and angle of the central control screen can be realized by a mechanical structure fixedly connected to the central control screen.

[0060] In summary, the method provided by the embodiment of the present application obtains the position information of the imaging interference area and the imaging display area on the window glass by acquiring the eye ellipse position information, the rearview mirror position information, and the central control screen position information, and considers the background brightness information and the imaging brightness information of the imaging display area of the window glass. Based on the above position information and brightness information, adjust the position and brightness of the central control screen, reduce the influence of the projection of the central control screen on the window glass on the driver's observation of the rearview mirror image, and improve driving safety.

[0061] In some examples, generating the central control screen control instruction through the above imaging interference area position information, the above imaging display area position information, the above background brightness information, and the above imaging brightness information includes:

[0062] Obtain the imaging coincidence degree according to the above imaging interference area position information and the above imaging display area position information;

[0063] Obtain the visual contrast based on the above background brightness information and the above imaging brightness information;

[0064] Generate the above central control screen control instruction through the above imaging coincidence degree and the above visual contrast.

[0065] Exemplarily, obtain the imaging coincidence degree according to the interference area position information and the imaging display area position information. The imaging coincidence degree is used to characterize the interference degree of affecting the driver's observation of the rearview mirror image. The coincidence degree is the proportion of the projection of the imaging area in the interference area. The higher the coincidence degree, the more serious the interference area is affected by the projection of the central control screen. A possible method for determining the coincidence degree is as follows: First, determine the imaging display area, select feature points on the central control screen. The feature points can be the four corner positions of the central control screen, or other points, such as Figure 3 As shown, select any point A on the central control display screen, the eye ellipse E, and any point B at the imaging position. Make the normal line of the side window glass passing through point B, and the included angle between the light ray and the normal line is θ. Make the perpendicular line from A to this normal line intersect at C, with a distance of m, and the perpendicular line from E to this normal line intersect at D (in the plane of ABE), with a distance of n. The distance between points C and D is q. Let the distance between C and B be x, and obtain the information of point B by calculating x, so as to determine the position of imaging B. From Equation (1) and Equation (2), X can be determined:

[0066] From triangle ABC,

[0067]

[0068] From triangle BDE,

[0069]

[0070] According to the above method, the position information of the imaging display area of the entire central control screen on the side window glass can be obtained. Based on the imaging display area position information and the imaging interference area position information, the imaging coincidence degree can be obtained.

[0071] Visual contrast is used to judge the relationship between the imaging brightness and the background brightness. The larger the visual contrast, the clearer the imaging. In this application, the larger the visual contrast, the greater the impact of the projected image of the central control screen on the window glass on the driver's observation of the rearview mirror image. A possible visual contrast C is determined by Equation (3):

[0072]

[0073] In the formula: ΔL represents the difference between the background brightness and the imaging brightness; L b is the background brightness; L t is the imaging brightness.

[0074] According to the above image coincidence degree and visual contrast, control the position and brightness of the central control screen to avoid the projection of the central control screen on the window glass from affecting the driver's acquisition of traffic information behind the vehicle.

[0075] In summary, in the embodiment of this application, the imaging coincidence degree is obtained through the above imaging interference area position information and the above imaging display area position information, and the visual contrast is obtained according to the above background brightness information and the above imaging brightness information. The above central control screen control instruction is generated through the above imaging coincidence degree and the above visual contrast, so that the control instruction can be quantified, and the position and brightness of the central control screen can be accurately controlled.

[0076] In some examples, the above generation of the above central control screen control instruction through the above imaging coincidence degree and the above visual contrast includes:

[0077] In the case where the above imaging coincidence degree is less than or equal to the preset coincidence degree, generate a central control screen position control instruction according to the above imaging coincidence degree;

[0078] Take the above central control screen position control instruction as the above central control screen control instruction.

[0079] Exemplarily, a developer or user can preset a preset coincidence degree in advance. The preset coincidence degree can be determined according to the adjustment ability of the position of the central control screen. The adjustment ability of the central control screen position can be the maximum displacement of the central control screen adjustment, or the maximum angle of the central control screen adjustment, or the result of comprehensively considering the maximum displacement and the maximum angle. When the imaging coincidence degree is less than or equal to the preset coincidence degree, it means that by adjusting the position or angle of the central control screen, the imaging display area can be completely outside the imaging interference area, that is, by adjusting the position or angle, the influence of the projection imaging of the central control screen on the driver's view of the rearview mirror can be eliminated.

[0080] In summary, the method provided by the embodiment of the present application presets a preset coincidence degree according to the adjustment ability of the central control screen position. When the imaging coincidence degree is less than or equal to the preset coincidence degree, it is considered that at this time, by only adjusting the position of the central control screen, the influence of the projection imaging of the central control screen on the driver's view of the rearview mirror can be eliminated. At this time, a central control screen position control instruction is generated according to the imaging coincidence degree, and the above central control screen position control instruction is used as the above central control screen control instruction, so that the central control screen control method is more convenient.

[0081] In some examples, generating the central control screen control instruction by the imaging coincidence degree and the visual contrast includes:

[0082] When the imaging coincidence degree is greater than the preset coincidence degree, a central control screen brightness control instruction is generated according to the visual contrast;

[0083] The central control screen brightness control instruction is used as the central control screen control instruction.

[0084] Exemplarily, when the imaging coincidence degree is greater than the preset coincidence degree, it is considered that adjusting the position of the central control screen cannot make the imaging display area completely outside the imaging interference area. At this time, a central control screen brightness control instruction is generated according to the visual contrast, and the brightness of the central control screen is adjusted according to the central control screen brightness control instruction, so as to reduce the imaging contrast and weaken the influence of the projection image of the central control screen on the driver.

[0085] In summary, the method provided by the embodiment of the present application judges the effect of the central control screen position adjustment by comparing the imaging coincidence degree and the preset coincidence degree. When the imaging coincidence degree is greater than the preset coincidence degree, it is judged that the influence of the projection image on the driver cannot be completely eliminated by adjusting the position of the central control screen. At this time, a central control screen brightness control instruction is generated through the contrast to control the screen brightness, and the influence of the projection image of the central control screen on the driver is weakened by adjusting the screen brightness. This method can flexibly switch the control scheme according to the adjustment ability of the central control screen position, and the control scheme is more intelligent.

[0086] In some examples, generating a center control screen brightness control instruction based on the above visual contrast includes:

[0087] When the above visual contrast is greater than the above contrast adjustment threshold, generating a center control screen brightness control instruction based on the above visual contrast.

[0088] Exemplarily, by comparing the magnitudes of the visual contrast and the contrast adjustment threshold, it can be used to determine whether the current projected image can truly affect the driver's view of the rearview mirror. When the visual contrast is greater than the above contrast adjustment threshold, it is considered that the current projected image will affect the driver, generating a center control screen brightness control instruction based on the visual contrast, and using this center control screen brightness control instruction to control the brightness of the center control screen, eliminating the impact on the driver caused by the projection of the center control screen on the window glass.

[0089] In summary, for the method provided in the embodiments of the present application, by comparing the magnitudes of the visual contrast and the contrast adjustment threshold, it is determined whether the projection of the center control screen on the window glass can truly affect the driver. If there is no impact, there is no need to adjust. If there is indeed an impact, then a center control screen brightness control instruction is generated based on the visual contrast to control the brightness of the center control screen, making the control method more intelligent.

[0090] In some examples, the above method includes:

[0091] Obtaining the ambient light intensity;

[0092] Determining a contrast adjustment threshold according to the above ambient light intensity.

[0093] Exemplarily, by comparing the magnitudes of the visual contrast and the contrast adjustment threshold, it can be used to determine whether the current projected image can truly affect the driver's view of the rearview mirror. However, under different lighting conditions, the contrast adjustment threshold can change. In one possible method for determining the contrast threshold, the lighting condition is obtained according to the light intensity, and the lighting condition is divided into day and night. Among them, the day is further divided into standard day conditions and direct sunlight during the day. As shown in Table 1, the contrast adjustment threshold under standard day conditions is 0.67, the contrast adjustment threshold under direct sunlight during the day is 0.5, and the contrast threshold under night conditions is 0.8. When the visual contrast is less than or equal to the contrast adjustment threshold, the projected image will not affect the driver's view of the rearview mirror, and no adjustment is required.

[0094]

[0095]

[0096] Table 1

[0097] In summary, the method proposed in the embodiment of the present application adjusts the contrast adjustment threshold according to the light intensity, so that the brightness adjustment of the central control screen can meet the requirements of the current light intensity, making the control method more targeted and flexible.

[0098] In some examples, the above method further includes:

[0099] Obtaining the adjustment margin information of the central control screen according to the above central control screen position information;

[0100] The above generating the central control screen control instruction through the above imaging coincidence degree and the above visual contrast includes:

[0101] Generating the central control screen control instruction through the above imaging coincidence degree, the above visual contrast and the above adjustment margin of the central control screen.

[0102] Exemplarily, the adjustment margin of the central control screen is obtained through the central control screen position information. For example, the position adjustment range of the central control screen is -10 to 10 cm, and the current position is +5 cm. Then the positive adjustment margin is 5 cm, and the negative adjustment margin is 15 cm. The adjustment direction and distance of the central control screen are judged according to the imaging coincidence degree. When the adjustment distance exceeds the adjustment margin, for example, it is necessary to adjust forward by 7 cm, but the current adjustment margin is 5 cm in the positive direction, and the image display area cannot be moved outside the imaging interference area by adjusting the screen position. At this time, the central control screen brightness adjustment instruction can be generated through the visual contrast, and the brightness of the central control screen is adjusted through the central control screen brightness adjustment instruction to eliminate the influence of the projection of the central control screen on the window on the driver.

[0103] In summary, the method provided in the embodiment of the present application also takes into account the adjustment margin of the central control screen at the current position, and comprehensively controls the central control screen according to the adjustment margin, imaging coincidence degree and visual contrast, making the control method more intelligent and more in line with the actual situation.
