Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle terminal, and in particular to a light shielding device adjusting method and system, a vehicle and a storage medium. BACKGROUND

[0002] With the progress of science and technology and the development of society, the number of cars continues to increase, and cars have become a common means of transportation for people.

[0003] In order to prevent the influence of sunlight during driving, sun visors are usually arranged above the driver's seat and the front passenger's seat, and sunshades and other light shielding devices are arranged on other windows (such as left and right windows, sunroofs, rear windows, etc.). In reality, some vehicle passengers (such as old people, children or people unfamiliar with vehicles) do not have the ability to adjust the light in the vehicle. In the case that the rear passengers cannot clearly express or give necessary feedback, the front passengers cannot accurately know the light conditions of the rear passengers. If the front passengers assist in adjusting, they need to look back and confirm visually to know whether the light shielding device has been adjusted to the appropriate position, which is easy to cause driving distraction and driving danger. Moreover, users usually do not know what adjustment effect can be achieved by different adjustment amounts of the adjusting device, and it may take multiple adjustment processes to achieve the ideal adjustment effect if the user directly adjusts the light shielding device, which is relatively cumbersome to operate.

[0065] The example embodiments will now be described in detail with reference to the drawings. When the description is made with reference to the drawings, the same numbers on different drawings represent the same or similar elements. These embodiments described in the example embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0066] The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the present application and the appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0067] It should be understood that, although the terms first, second, third, etc. can be used herein to describe various information, these terms are not intended to denote a particular order or hierarchy. These terms are used only to distinguish one from another. For example, a first information can be termed a second information, and, similarly, a second information can be termed a first information, without departing from the scope of the present application. As used herein, the term "if' can be interpreted to mean "when" or "responsive to the determination" or "in response to the determination" depending on the context.

[0068] In the related art, in order to prevent the influence of sunlight during driving, a sun visor is usually arranged above the driver's seat and the front passenger's seat, and a sunshade curtain or other light shielding device is arranged on other windows (such as left and right windows, a sunroof, a rear window, etc.). The control buttons of the light shielding device are usually arranged at two positions, for example, for a sunshade curtain, one control button is arranged near the corresponding window of the sunshade curtain so that the passenger near the window can control it, and the other control button is arranged near the driver so that the driver can control it.

[0069] In reality, some vehicle passengers (such as old people, children or people unfamiliar with vehicles) do not have the ability to adjust the light in the vehicle. In the case that the rear passengers cannot give necessary feedback, the front passengers cannot accurately know the light conditions of the rear passengers. If the front passengers assist in adjusting, for example, the driver adjusts the sunshade curtain using the control button arranged near the driver, and directly adjusts the sunshade area of the sunshade curtain to the maximum, it will affect the viewing needs of the rear passengers and reduce the riding experience. In the case that the rear passengers cannot give necessary feedback, the driver needs to look back and confirm whether the sunshade curtain has been adjusted to the appropriate position, but this can easily cause driving distraction and driving danger. Moreover, users are usually not clear about what adjustment effect can be achieved by different adjustment amounts of the light shielding device, and if the user directly adjusts the light shielding device, it may take several adjustment processes to achieve the ideal adjustment effect, which is relatively cumbersome to operate.

[0070] To solve the problems in the related art, the embodiments of the present application provide a light shielding device adjustment method applied to a vehicle. The vehicle can determine the irradiation range of sunlight in the vehicle through the light transmission area, and display an in-vehicle light image according to the irradiation range on the interactive interface of the vehicle. The in-vehicle light image includes an actual light area irradiated by sunlight in the vehicle. Therefore, the front passengers can clearly understand the sunlight distribution in the vehicle through the in-vehicle light image, and perform related adjustment operations based on the in-vehicle light image. Moreover, the user input information can directly indicate which places in the vehicle are irradiated by sunlight and which places are not irradiated by sunlight, and then the vehicle can obtain the expected light area in the vehicle indicated by the user input information, and automatically adjust the light shielding device according to the difference between the actual light area and the expected light area.

[0071] In some embodiments, the light shielding device adjustment method can be applied to a vehicle, such as being executed by a processor (such as an electronic control unit, ECU) in the vehicle. For example, please refer to Figure 1 , Figure 1The sunshade device adjusting system provided by the embodiment of the present application is installed on a vehicle, and a vehicle window of the vehicle forms a light-transmitting area. The system comprises at least one sunshade device 10 corresponding to at least one vehicle window of the vehicle, a vehicle-mounted display 20, a memory 30, a processor 40, and executable instructions stored on the memory 30 and executable on the processor 40; wherein the processor 40 can execute the executable instructions for indicating the sunshade device adjusting method provided by the embodiment of the present application to adjust the sunshade device; and the vehicle-mounted display 20 is used to provide an interactive interface and display an indoor light image so that a user can clearly know the sunlight distribution in the vehicle and take corresponding sunshade measures.

[0072] Of course, in addition to the above-mentioned components, other components can also be included, such as a satellite positioning module (for determining the latitude and longitude information of the vehicle), a light sensor (for detecting the light intensity of sunlight), a navigation planning module (such as providing a navigation planning route, predicted driving time information, driving direction in vehicle driving, etc.), a communication module (for communicating with external devices, such as obtaining the current specific date, time, etc. from external devices), and / or a microphone (for collecting voice input information of the user), etc. The specific settings can be made according to the actual application scenario, and the embodiment does not make any limitation thereto.

[0073] Next, the sunshade device adjusting method provided by the embodiment of the present application is exemplarily described. Figure 2 Figure 2 A flowchart of a sunshade device adjusting method provided by the embodiment of the present application is shown. The method is applied to a vehicle, and optionally, the method is executed by a processor in a sunshade device adjusting system installed in the vehicle. At least one vehicle window of the vehicle is provided with a sunshade device, and the vehicle window forms a light-transmitting area; for example, the left and right vehicle windows or the rear vehicle window of the vehicle are provided with sunshades. The method comprises:

[0074] In step S101, the irradiation range of sunlight in the vehicle through the light-transmitting area is determined, and an indoor light image is displayed on the interactive interface of the vehicle according to the irradiation range, wherein the indoor light image comprises an actual light area in the vehicle irradiated by sunlight.

[0075] In step S102, in response to the displayed indoor light image, an expected light area in the vehicle indicated by user input information is obtained.

[0076] In step S103, the sunshade device is adjusted according to the difference between the actual light area and the expected light area.

[0077] ​In this embodiment, the front row person can clearly understand the sunlight distribution in the vehicle through the in-vehicle light image, and based on the in-vehicle light image, the front row person can perform related adjustment operation without looking back to confirm, so as to accurately adjust the light shielding device. The user only needs to indicate the desired light condition in the vehicle (i.e., which place wants to be illuminated by sunlight and which place does not want to be illuminated by sunlight), without needing to pay attention to the specific adjustment amount of the sunshade device. The vehicle finely adjusts the light shielding device according to the difference between the actual light area and the desired light area, realizes a fine adjustment process, reduces the user operation steps, and is beneficial to improve the operation experience of the user and the adjustment effect of the light shielding device.

[0078] For example, step S101 can be executed under the instruction of the user, such as the user triggering the light display control. The vehicle executes step S101 in response to the user's triggering operation of the light display control. For example, step S101 can be automatically executed when it is detected that the area of the light transmission region changes, so as to display the in-vehicle light condition after the area of the light transmission region changes, so as to let the user clearly understand the actual sunlight distribution in the vehicle.

[0079] In some embodiments, the vehicle includes a plurality of windows. The car window is an important part of the entire vehicle body, and is designed to meet the needs of lighting, ventilation and field of view of the driver and passengers. The car window includes front and rear windows, left and right side windows, and top windows. At least one window of the vehicle is provided with a light shielding device, such as a sunshade curtain or a glass capable of changing the light transmittance corresponding to the side window and / or the top window of the vehicle.

[0080] The car window forms a light transmission region. For example, when the car window is provided with a light shielding device, the vehicle can determine the area of the light transmission region formed by the car window according to the area of the car window and the area of the light shielding region formed by the light shielding device. The area of the light shielding region and the area of the light transmission region are negatively correlated, that is, the larger the area of the light shielding region, the smaller the area of the light transmission region, and vice versa. The area of the light transmission region is different, and the in-vehicle light condition is also different.

[0081] In addition, there can be some windows in the vehicle without a light shielding device, so the range of the in-vehicle light irradiated by the sun through the light transmission region of these windows cannot be adjusted. Or, the area of the light shielding device provided on some windows is not large enough (such as a sunshade provided on the front window only for shielding part of the light of the sun passing through the front window so that the sunlight cannot irradiate the driver's eyes), and in the case that the light shielding region formed by the sunshade has been adjusted to the maximum, the sunlight that can still enter from the light transmission region of the front window cannot be adjusted.

[0082] In some embodiments, the vehicle further comprises a light sensor for detecting the intensity of sunlight. When performing step S101, the vehicle first determines whether there is sunlight at the location of the vehicle according to the intensity of sunlight detected by the light sensor. If the light sensor detects sunlight, the vehicle determines the irradiation range of sunlight in the vehicle through the light-transmitting region and displays an indoor light image on the interactive interface of the vehicle according to the irradiation range. If the light sensor detects no sunlight, the vehicle does not need to determine the indoor light information at the location of the vehicle, and can output a prompt information of no indoor light on the interactive interface, thereby saving computational resources.

[0083] In other embodiments, the vehicle has a networking function. When performing step S101, the vehicle can first obtain weather information at the location of the vehicle from a preset weather platform. If the weather information indicates sunny weather, the vehicle determines the irradiation range of sunlight in the vehicle through the light-transmitting region. If the weather information indicates cloudy weather, the vehicle does not need to determine the indoor light information at the location of the vehicle, and can output a prompt information of no indoor light on the interactive interface, thereby saving computational resources.

[0084] In some embodiments, when the light sensor detects sunlight or the weather information obtained from the preset weather platform indicates sunny weather, the vehicle needs to determine the irradiation range of sunlight in the vehicle through the light-transmitting region. Here, two implementation manners for determining the irradiation range are exemplarily provided. One is to calculate the irradiation range of sunlight in the vehicle according to the solar elevation angle, the solar azimuth angle and the like. The other is to determine the irradiation range of sunlight in the vehicle according to the image collected by the camera in the vehicle. Different implementation manners can be selected according to the situation of the obstacles around the vehicle that affect sunlight, so as to balance between improving accuracy and reducing power consumption.

[0085] In some embodiments, the vehicle is provided with at least one detection sensor (such as a camera, a laser radar or a millimeter wave radar, etc.) for perceiving the environment. The vehicle can determine whether there is an obstacle that blocks sunlight by the data collected by the detection sensor. In one example, the vehicle can calculate the solar elevation angle by using time information and vehicle location information, and then determine the solar azimuth angle. Then, the vehicle determines whether there is an obstacle higher than the vehicle in the range of the solar azimuth angle according to the data collected by the detection sensor. If there is an obstacle higher than the vehicle, it is determined that there is an obstacle that blocks sunlight around the vehicle.

[0086] In a possible implementation, the vehicle interior is further provided with at least one camera, which is configured to capture a panoramic image of the entire space in the vehicle. In the case where there are obstacles around the vehicle that block sunlight, the vehicle acquires the panoramic image captured by the at least one camera, and determines the irradiation range of sunlight in the vehicle that passes through the light-transmitting region according to the brightness and color of the panoramic image. In this embodiment, the light distribution in the vehicle is determined by the panoramic image captured by the camera in the case where there are obstacles around the vehicle that block sunlight, which helps to improve the accuracy of the determination of the irradiation range and eliminate the interference of the obstacles that block sunlight.

[0087] In another possible implementation, in the case where there are no obstacles around the vehicle that block sunlight, the vehicle can determine the solar altitude angle and the solar azimuth angle by using time information and vehicle position information; then determine the relative azimuth angle of the sun and the vehicle window according to the orientation information of the vehicle, the solar azimuth angle, and the position of the vehicle window in the vehicle; and further determine the irradiation range of sunlight in the vehicle that passes through the light-transmitting region according to the area of the light-transmitting region corresponding to the vehicle window, the solar altitude angle, and the relative azimuth angle. In this embodiment, the sunlight irradiation range in the vehicle is directly calculated according to the solar altitude angle, the solar azimuth angle, and other information without the camera, which helps to reduce power consumption.

[0088] Here, the solar altitude angle and the solar azimuth angle are described. Please refer to Figure 3 The solar altitude angle refers to the angle between the direction of sunlight and the horizontal plane at a certain location on the earth. When the solar altitude angle is 90°, the solar radiation intensity is the largest. The greater the degree of the sun's oblique incidence on the ground (that is, the smaller the solar altitude angle), the smaller the solar radiation intensity. The solar altitude angle at each location on the morning and evening lines is 0°, which indicates that the location is experiencing day and night alternation. The solar altitude at each location on the day hemisphere is greater than 0°, which indicates day. The solar altitude at each location on the night hemisphere is less than 0°, which indicates night. The solar altitude angle changes with the local time and the solar declination. The solar declination (equal to the solar subsolar point latitude) is denoted by δ, the geographic latitude of the observation site is denoted by φ (the solar declination and the geographic latitude are both positive for northern latitude and negative for southern latitude), the local time (hour angle) is denoted by t, and the solar altitude angle is denoted by h, and the calculation formula of the solar altitude angle is: That is to say, the solar altitude angle at a certain location at a certain time point can be determined when the time and the geographic position are determined.

[0089] ​The solar azimuth angle is the angle of the sun in the azimuth, which is usually defined as the angle measured along the horizon from the north clockwise. The azimuth angle is taken as the north direction of the target object (the same as the north direction of the central meridian in the same geographical division / zone) as the starting direction, i.e. 0 degree. The value range is 0-360 degrees, and the calculation rotation mode is: taking the target object as the axis, taking the north direction of the target object as the starting point, and rotating clockwise for one circle, the azimuth angle gradually increases to 360°. Therefore, the solar azimuth angle is generally measured as the angle from the north direction of the target object as the starting direction to the incident direction of the sunlight as the ending direction in the clockwise direction. The solar azimuth angle is determined according to the solar altitude angle, the time angle of the calculation time, the solar declination and the geographical latitude, and the calculation mode of the solar azimuth angle follows the international general calculation method.

[0090] For example, the vehicle can obtain the current time information and the current vehicle position information (such as the latitude and longitude of the location where the vehicle is located) from the related sensors (such as the clock and the satellite positioning module) in the vehicle, and then determine the solar altitude angle and the solar azimuth angle by using the time information and the vehicle position information in combination with the solar declination.

[0091] Then, the vehicle can determine the azimuth angle of the window according to the orientation information of the vehicle and the position of the window in the vehicle, and further determine the relative azimuth angle between the sun and the window according to the azimuth angle of the window and the solar azimuth angle. The azimuth angle of the window refers to the angle of the window in the azimuth, such as the angle between the window and the north direction. It can be understood that other directions can also be taken as the reference basis, and the present embodiment does not make any limitation in this regard.

[0092] For example, the orientation information of the vehicle can be determined according to at least one of the following information: the driving direction of the vehicle according to the navigation track, the azimuth information measured by the compass in the vehicle, or the steering information fed back by the electric power steering system in the vehicle; of course, it can also be determined in other ways, and the present embodiment does not make any limitation in this regard. The orientation information indicates the angle of the vehicle in the azimuth, such as the angle between the vehicle head and the north direction. In one example, please refer to Figure 4 , the vehicle can determine the orientation information of the vehicle according to the angle between the driving direction of the vehicle indicated in the navigation interface and the north direction.

[0093] For example, please refer to Figure 5 , the azimuth angles of the front window and the top window are equal to the orientation information, and the azimuth angles of the left and right windows and the rear window are obtained by processing the orientation information according to the relative positions between the windows and the front window. In one example, the azimuth angle of the north direction is 0°, the clockwise direction is positive, and the counterclockwise direction is negative. Please refer to Figure 5, assuming that the azimuth angle of the front window and the top window is B, the azimuth angle of the right window is C, the azimuth angle of the rear window is D, and the azimuth angle of the left window is E. Taking the preset four-face shape of the vehicle as an example, it is B = the heading information; C = B + 90°; D = B + 180°; and E = B + 270°. Those skilled in the art can understand that the conversion relationship of the azimuth angles of the different windows is only for example, and the specific conversion relationship can be changed according to the vehicle model, which is not limited in the embodiment; the conversion relationship can be calibrated by the vehicle before leaving the factory and stored in the vehicle, or obtained by the vehicle from the server of the vehicle through over-the-air upgrade. Please refer to Figure 6 Figure 6 N in the formula (1) represents the north direction), and taking the front window as an example, assuming that the relative azimuth angle of the front window is BS, the azimuth angle of the sun is A, and the azimuth angle of the front window is B, it is BS = A - B. Among them, for the front, rear, left and right four windows, when the relative azimuth angle is between -90° and 90°, the sunlight can pass through the light transmission area of the window and enter, and when it exceeds this range, the sunlight cannot enter. For the light transmission area of the top window, as long as there is sunlight, it can enter the vehicle.

[0094] Finally, the vehicle can determine the irradiation range of the sunlight in the vehicle through at least one of the light transmission areas of the windows according to the area of the light transmission area, the sun elevation angle and the relative azimuth angle. Among them, for the window, the irradiation range of the sun in the vehicle is the projection range of the light transmission area formed by the window in the vehicle, and the area of the light transmission area, the sun elevation angle and / or the relative azimuth angle are different, and the projection range of the light transmission area in the vehicle is also different.

[0095] In one example, taking one of the windows as an example, please refer to Figure 7 , assuming that the relative azimuth angle of the left window is ES, the sun elevation angle is h, the projection direction is determined according to the sun elevation angle and the relative azimuth angle, and the light transmission area of the left window is projected into the vehicle according to the projection direction, then the irradiation range of the sunlight in the vehicle through the light transmission area of the left window can be obtained, wherein the area of the irradiation range is related to the area of the light transmission area and the projection direction. Figure 7 Z-axis in the formula (2) represents the direction perpendicular to the ground, Y-axis represents the azimuth of the light transmission area of the left window, and X-axis represents the direction perpendicular to the azimuth of the light transmission area of the left window.

[0096] In some embodiments, after the vehicle determines the irradiation range of the sunlight in the vehicle through the light transmission area formed by the window on the vehicle according to the above implementation manner, the vehicle can display the interior lighting image in the vehicle according to the irradiation range and in combination with the internal structure of the vehicle on the interactive interface of the vehicle, please refer to Figure 8 ​The in-vehicle light illumination image includes an actual light illumination area in the vehicle that is illuminated by sunlight, thereby providing intuitive reference for the user.

[0097] For example, the in-vehicle light illumination image indicates components in the vehicle that are within the illumination range. The components in the vehicle include, but are not limited to, a seat, a door, a seat cushion, a handle, a steering wheel, an instrument panel, a center console, a carpet, and the like. In one example, referring to the in-vehicle light illumination image shown in Figure 8 The sun is shown to illuminate from the left rear side. The in-vehicle light illumination image shows that the sun illuminates a portion of the seat and a portion of the door, so that the user can clearly understand the sunlight distribution of the vehicle and make reference for the light shielding decision.

[0098] For example, the vehicle further includes a light sensor. When the in-vehicle light illumination image is displayed, the brightness of the actual light illumination area in the in-vehicle light illumination image can be determined according to the light intensity detected by the light sensor. For example, the brightness of the actual light illumination area is positively correlated with the light intensity detected by the light sensor. The stronger the light intensity, the brighter the light illumination area, thereby providing more reference information for the user to assist the user in making a light shielding decision.

[0099] In some embodiments, based on the in-vehicle light illumination image displayed on the interactive interface, the user can adjust the light shielding device according to the in-vehicle light illumination image. Further, to simplify the operation steps of the user and improve the operation experience of the user, the user can input the desired light illumination area according to the actual needs (i.e., the user only needs to input which part of the vehicle is illuminated by sunlight and which part of the vehicle is not illuminated by sunlight), and then the vehicle can obtain the desired light illumination area in the vehicle indicated by the user input information in response to the displayed in-vehicle light illumination image. For example, the user input information includes voice input information and / or operation information for adjusting the actual light illumination area. Then, the vehicle adjusts the light shielding device according to the difference between the actual light illumination area and the desired light illumination area, thereby accurately and finely adjusting the light shielding device according to the desired adjustment effect. In one example, referring to Figure 9 and Figure 10 , Figure 9 The in-vehicle light illumination image including the actual light illumination area and the in-vehicle desired light illumination image including the desired light illumination area are shown. The vehicle adjusts the light shielding area of the light shielding device from the effect shown in (1) to the effect shown in (2) according to the difference between the actual light illumination area and the desired light illumination area in Figure 9 Figure 10

[0100] ​​In one possible implementation, taking the example in which the user input information includes operation information for adjusting the actual illumination area, an adjustment control is also displayed on the interactive interface, and the adjustment control is superimposed on the interior lighting image. The adjustment control indicates the dividing line between the shading area formed by the shading device and the translucent area. The adjustment control is used to change the area of ​​the actual illumination area, thereby changing the area of ​​the shading area and the translucent area, and the area changes of the two are negatively correlated.

[0101] For an example, see Figure 11 , taking the top window as an example, Figure 11 (2) in (1) is the interior lighting image of the vehicle at a certain solar altitude angle and a certain relative azimuth angle. The entire dotted frame in (2) is the projection range of the roof window in the vehicle. The gray dotted frame portion is the illumination range of the sun through the light-transmitting area of ​​the roof window in the vehicle (i.e., the actual illumination area). The white dotted frame portion is the projection range of the shading area formed by the shading device of the roof window in the vehicle. The dividing line between the shading area formed by the shading device and the light-transmitting area is projected into the vehicle, i.e., the dividing line between the gray dotted frame portion and the white dotted frame portion. For example, please refer to Figure 11 The adjustment control includes an adjustment line, which indicates the display position of the boundary line between the shading area formed by the shading device and the light-transmitting area in the interior lighting image (i.e. Figure 11 The adjustment line can change its position under the operation of the user, thereby changing the area of ​​the actual illumination area.

[0102] like Figure 11 As shown, Figure 11 (2) in the figure shows arrows in two directions, one in the upper and one in the lower direction, near the adjustment line (for providing adjustment prompts to the user). The arrows in the upper and lower directions indicate that the adjustment line can be moved up and down. When the user moves the adjustment line up, the actual illuminated area is reduced, that is, the shading area formed by the shading device is increased while the light-transmitting area of ​​the top window is reduced; when the user moves the adjustment line down, the actual illuminated area is increased, that is, the shading area formed by the shading device is decreased while the light-transmitting area of ​​the top window is increased.

[0103] The vehicle can determine a position of a desired boundary line between the light-shielded area and the light-transmitted area formed by the light-shielding device according to the desired light-illumination area indicated by the adjusted adjustment control, and then adjust the light-shielding device according to a position difference between the position of the actual boundary line corresponding to the actual light-illumination area and the position of the desired boundary line. For example, the vehicle can determine an actual size of the desired light-transmitted area by back projection according to the desired light-illumination area indicated by the adjusted adjustment control, the solar altitude angle, and the relative azimuth angle (between the sun and the vehicle window), and then calculate the position of the desired boundary line between the light-shielded area and the desired light-transmitted area formed by the light-shielding device. In this embodiment, the user can adjust the adjustment control according to actual needs to determine the desired light-illumination area, and then the vehicle can adjust the light-shielding device according to the user's desired adjustment effect. The user does not need to know the specific adjustment amount of the light-shielding device, which is beneficial to simplify the adjustment steps. The vehicle automatically implements a fine adjustment process according to the user's desired adjustment effect, and improves the adjustment accuracy.

[0104] For example, the light-shielding device includes a sunshade curtain and a driving motor for driving the sunshade curtain. The vehicle can determine a target driving amount of the driving motor according to the position difference between the position of the actual boundary line corresponding to the actual light-illumination area and the position of the desired boundary line, and drive the driving motor using the target driving amount to drive the sunshade curtain connected to the driving motor to the position of the desired boundary line.

[0105] For example, the light-shielding device includes a glass with variable light transmission rate arranged on the vehicle window, and the glass includes a plurality of independently controlled glass areas. The vehicle can determine a target glass area between the position of the actual boundary line corresponding to the actual light-illumination area and the position of the desired boundary line, and reduce the light transmission rate of the target glass area. The lower the light transmission rate of the glass, the stronger the ability to block light, and the higher the light transmission rate, the weaker the ability to block light. In this embodiment, the target glass area is reduced to block sunlight.

[0106] For example, after the user operates the adjustment line, the vehicle can display a desired light-illumination image in the vehicle in real time on the interactive interface according to the position of the adjusted adjustment line, and the desired light-illumination image includes the desired light-illumination area, such as (2) in Figure 9

[0107] ​In another possible implementation, taking the input information as an example, the vehicle includes a microphone, and after the vehicle displays the in-vehicle light image on the interactive interface, the vehicle can start the microphone to collect voice input information of the user, and then perform voice recognition on the voice input information to obtain a voice recognition result. According to the irradiation of each seat area in the vehicle indicated by the voice recognition result, the desired light area in the vehicle is determined, so that the vehicle can adjust the light shielding device according to the difference between the actual light area and the desired light area. In one example, the voice input information includes, but is not limited to, "the rear row is not irradiated by sunlight, or the left rear row is not irradiated by sunlight, or the left rear row seat is irradiated by 20% of sunlight", so that the vehicle can determine the desired light area according to the voice recognition result of the voice input information.

[0108] Exemplarily, in the case that the light shielding area formed by the light shielding device is adjusted to the maximum, if the desired light area cannot still be met, prompt information that the light shielding device cannot continue to adjust is output, and the light shielding device remains in the current adjustment state (that is, the light shielding area formed by the light shielding device is adjusted to the maximum). The prompt information can be visual information and / or auditory information.

[0109] Exemplarily, the light shielding device includes a sunshade curtain and a driving motor for driving the sunshade curtain. The vehicle can determine a target driving amount of the driving motor according to the difference between the actual light area and the desired light area, and drive the driving motor using the target driving amount.

[0110] Exemplarily, the light shielding device includes glass with variable light transmittance arranged on the vehicle window, and the glass includes a plurality of independently controlled glass areas. The vehicle can determine a target glass area to be adjusted according to the difference between the actual light area and the desired light area, and reduce the light transmittance of the target glass area. The lower the light transmittance of the glass, the stronger the ability of the glass to shield light, and the higher the light transmittance, the weaker the ability of the glass to shield light. The embodiment plays a role in shielding sunlight by reducing the light transmittance of the target glass area.
