When sunlight irradiates to eyes of a driver, the driving experience of the driver can be greatly reduced due to the influence on the visual state of the driver, in order to enable the driver to obtain better driving experience, a shading device 20 for shading the sunlight is generally arranged in a vehicle, such as a sun visor, when the sunlight irradiates to the eyes of the driver, the driver can shift the sun visor to change the position of the sun visor, so that the sun visor can shade the sunlight irradiating to the eyes of the driver, so as to obtain better visual state, but the sun visor can also shade the visual field of the driver, so that the visual field range of the driver is narrowed, so that the driver can pack the sun visor in order to obtain better visual field range, for example, when the sunlight can irradiate to the eyes of the driver and can not irradiate to the eyes of the driver, when the sunlight can irradiate to the eyes of the driver, the driver can select to adjust the sun visor to shade the sunlight to obtain better visual state, and when the sunlight can not irradiate to the eyes of the driver, the driver can pack the sun visor in order to obtain better visual field of view range, so that the driver can always need to take the visual state and the range of the sun visor into consideration in the process of the driver, and there are tedious factors of adjusting the driver.

Aiming at the problems in the related art, the embodiment of the application provides an adjusting method of the shading device 20, which realizes automatic adjustment of the shading device according to the irradiation condition of sunlight, does not need manual adjustment of a driver, and reduces the operation steps of the driver. According to the embodiment, a target elevation angle and a target relative azimuth angle range which are suitable for the positions of the eyes of a driver can be obtained in advance according to the relative relation between the eyes of the driver and a vehicle window, the target elevation angle indicates the maximum solar elevation angle which can irradiate the eyes of the driver, if the solar elevation angle exceeds the target elevation angle, the maximum solar elevation angle cannot irradiate the eyes of the driver, and if the solar elevation angle is lower than the target elevation angle, the maximum solar elevation angle can irradiate the eyes; the target relative azimuth angle range indicates that sunlight in the range can irradiate the eyes of the driver, so that the accuracy of the detection process of whether the subsequent sunlight irradiates the eyes is improved. Furthermore, in the actual driving process, the range of the solar altitude angle and the target relative azimuth angle can be determined by utilizing the time information, the vehicle position information, the vehicle orientation information and the like, and under the condition that the solar altitude angle is smaller than the target altitude angle and the relative azimuth angle is in the range of the target relative azimuth angle, the sunlight is determined to possibly irradiate the eyes of the driver, so that the vehicle carries out the automatic shading device 20 process. In the process of automatically adjusting the shading device 20 of the vehicle, the relative relationship between the eyes of the driver and the windows of the vehicle is used as a standard for adjustment, so the adjusting mode in the embodiment has the real-time effect through the time information and the targeted effect through the relative relationship between the eyes of the driver and the windows of the vehicle, and the effect of adaptively adjusting the shading device 20 at different times for different drivers is achieved.

In some embodiments, the shade device 20 adjustment method may be applied to a vehicle, executed by a processor 10 (e.g., ECU, electronic control unit) in the vehicle. Referring to fig. 1, fig. 1 is a system for adjusting a shade device 20 according to an embodiment of the present disclosure, where the shade device 20 is installed in a vehicle, and the system includes a shade device 20, a processor 10, a memory 30, and executable instructions stored in the memory 30 and executable on the processor 10; wherein, the processor 10 may execute executable instructions for instructing the adjusting method of the shading device 20 provided by the embodiment of the present application; the processor 10 executes the executable instructions and adjusts the shade device 20 such that the shade device 20 shades the sun from the eyes of the driver, thereby improving the driving experience of the driver.

Of course, in addition to the above components, other components may be included, such as, but not limited to, a satellite positioning module (for determining longitude and latitude information of the vehicle), a light sensor 50 (for detecting illumination intensity of sunlight), a navigation planning module (for providing a navigation planned route, a predicted driving time information, a driving direction of the vehicle during driving, and the like), a communication module (for communicating with an external device, such as obtaining a current specific date and time from the external device), a driving motor for driving the light shielding device 20, and the like, which may be specifically set according to an actual application scenario, and the embodiment does not limit the present invention in any way.

The following provides an exemplary explanation of the adjustment method of the light blocking device 20 according to the embodiment of the present application: referring to fig. 2, fig. 2 is a schematic flowchart illustrating an adjusting method of the light shielding device 20 according to an embodiment of the present disclosure. The method is applied to a vehicle, and is optionally executed by a processor 10 in a shading device 20 adjusting system installed in the vehicle, wherein the vehicle comprises a vehicle window arranged in front of a driving position and a shading device 20 corresponding to the vehicle window, and the method comprises the following steps:

in step S101, a solar altitude and a solar azimuth are determined using the time information and the vehicle position information.

In step S102, a relative azimuth angle of the sun and the vehicle is determined according to the vehicle orientation information and the sun azimuth angle.

In step S103, a predetermined target elevation angle and a target relative azimuth angle range are obtained; the target elevation angle and the target relative azimuth angle range are determined according to the relative relation between the eyes of the driver and the vehicle window; the target elevation angle and the target relative azimuth angle range are used to indicate sunlight that can shine to the eyes of the driver.

In step S104, if the solar altitude is smaller than the target altitude and the relative azimuth is within the target relative azimuth range, the shading device 20 is adjusted.

The embodiment can determine the target elevation angle and the target relative azimuth angle range in advance according to the relative relation between the eyes of the driver and the vehicle window, namely, the target elevation angle and the target relative azimuth angle range are suitable for the positions of the eyes of the driver, so that the accuracy of the detection process of whether the subsequent sunlight irradiates the eyes or not is improved. Furthermore, in the actual driving process, the range of the solar altitude angle and the target relative azimuth angle can be determined by utilizing time information, vehicle position information, vehicle orientation information and the like, and under the condition that the solar altitude angle is smaller than the target altitude angle and the relative azimuth angle is in the range of the target relative azimuth angle, the sunlight is determined to possibly irradiate the eyes of a driver, so that the automatic adjustment sun-shading device of the vehicle is realized, the manual adjustment of the driver is not needed, and the operation steps of the driver are reduced.

For example, steps S101 to S104 may be performed in response to a user instruction, such as a user triggering the sun visor automatic adjustment control, and the vehicle performs steps S101 to S104 in response to a triggering operation of the user. For example, steps S101 to S104 may be automatically performed when it is detected that the current environment has sunlight irradiation, so as to provide the driver with an accurate adjustment of the shade device 20 to shade the sunlight irradiating the eyes of the driver based on whether the sunlight irradiation is performed.

In some embodiments, the solar angle and solar azimuth are described herein: referring to fig. 3, the solar altitude refers to an angle between the incident direction of sunlight at a certain location on the earth and the ground plane. When the solar altitude angle is 90 degrees, the solar radiation intensity is maximum; the greater the sun is inclined to the ground (i.e., the smaller the solar altitude), the less the intensity of the solar radiation. The solar altitude angles of all places on the morning and evening line are 0 degrees, which indicates that day and night alternation is going on; the sun height in each place on the diurnal hemisphere is greater than 0 degrees, which indicates daytime; the sun's height is less than 0 deg. in each place over the night hemisphere, indicating a dark night. The solar altitude varies with the time of the locality and the declination of the sun. The solar declination (equal to the latitude of a solar direct point) is represented by delta, the geographical latitude of an observation place is represented by phi (the solar declination and the geographical latitude are positive for north latitude and negative for south latitude), the local time (time angle) is represented by t, the solar altitude angle is represented by h, and then the calculation formula of the solar altitude angle is provided:

wherein the calculation mode of the solar declination follows an international general calculation method. That is, with the time and geographic location determined, the solar altitude at a location at a point in time may be determined.

Solar azimuth is the angle of the sun in azimuth, which is generally defined as the angle measured clockwise from north along the horizon. The azimuth is calculated from the true north direction of the target (the same as the north direction of the central meridian within the same geographical division/zone), i.e., 0 degrees. The value range is 0-360 degrees, and the calculation rotation mode is as follows: the target object is taken as an axis, the north direction of the target object is taken as a starting point, the target object rotates for a circle in the clockwise direction, and the azimuth angle is gradually increased to 360 degrees. Therefore, the solar azimuth angle is generally an angle measured in a clockwise direction with the north direction of the target object as the starting direction and the incident direction of the solar light as the ending direction. The solar azimuth angle is determined according to the solar altitude angle, the time angle of calculation time, the solar declination and the geographical latitude, and the calculation mode of the solar azimuth angle follows an international general calculation method.

Considering that different positions of eyes of different drivers exist, the sunlight rays which can be irradiated to the eyes of the drivers are different when the different drivers drive the vehicle, so that the vehicle needs to determine a target elevation angle and a target relative azimuth angle range which can be irradiated to the eyes of the drivers before adjusting the shading device 20, and then the sunlight can be judged to be irradiated to the eyes through the target elevation angle and the target relative azimuth angle range; the target altitude angle is used for indicating the maximum sun altitude angle capable of irradiating the eyes of the driver, the maximum sun altitude angle cannot irradiate the eyes of the driver when the target altitude angle exceeds the angle, and the maximum sun altitude angle can irradiate the eyes of the driver when the target altitude angle is lower than the angle; the target relative azimuth angle range is used for indicating the sun azimuth angle capable of irradiating the eyes of the driver, that is, the eyes of the driver can be irradiated as long as the sun azimuth angle is within the target relative azimuth angle range. Therefore, the target elevation angle and the target relative azimuth angle range are used as a basis for judging that sunlight can irradiate the eyes, and the target elevation angle and the target relative azimuth angle range are determined according to the relative relation between the eyes of a driver and the vehicle window, so that the target elevation angle and the target relative azimuth angle range can be determined only by acquiring the positions of the eyes of the driver in advance.

There are many ways to determine the eye position information, such as calculating the position of the driver's eyes based on the depth image captured by the depth camera 40, or calculating the position of the driver's eyes based on the driver's height and height ratio information, or other ways to calculate the position of the driver's eyes.

In a possible implementation manner, the position of the eyes of the driver is determined by calculation based on the height information and the height ratio information of the driver, the height information of the driver needs to be determined in advance, the predetermined height information of the driver can be height information of a fixed driver input to the vehicle in advance, or a plurality of pieces of driver information input to the vehicle in advance, and the current driver is selected before the driver gets on the vehicle to enable the vehicle to determine to obtain the corresponding height information of the driver, or other manners capable of enabling the vehicle to obtain the height information of the driver can be adopted; after the vehicle acquires the height information of the driver, determining the height of the upper body of the driver in a sitting posture state according to the proportional information corresponding to different heights; the proportion information corresponding to different heights can be proportion information which is input in advance and is suitable for a driver of the vehicle, or can be determined according to the conditions such as region information, crowd information and the like, for example, when the vehicle mainly runs in Europe, the proportion information can be judged according to the proportion information of the whole heights in the Europe region, and similarly, the proportion information can also be judged according to the proportion information of the whole heights of the crowd of taxi drivers when the vehicle is a taxi; after the vehicle acquires the height information of the driver and the proportional information corresponding to different heights, the upper half height of the driver in a sitting posture state can be calculated, and the position of the eyes of the driver can be determined according to the position information of the driver seat and the upper half height because the driver sits on the driver seat with the upper half body. In the process of calculating and determining the positions of the eyes of the driver according to the height information and the height proportion information of the driver, the position information of the driver seat is required to be determined in consideration of the fact that the position information of the driver seat is different due to the actual adjustment condition of the user.

Illustratively, the vehicle includes a first drive motor for adjusting a driver seat position; wherein the first drive motor is a power device for adjusting the driver's seat, so that a position after the driver's seat is currently adjusted can be determined based on drive information of the first drive motor, initial position information for the driver's seat is obtained based on the vehicle model, so that position information of the driver's seat can be determined based on the initial position information of the driver's seat and the drive information of the first drive motor; the initial position information indicates position information of the driver seat which is not adjusted by the first driving motor, the current position information of the driver seat can be determined by combining the driving information of the first driving motor on the basis of the initial position information, and the eye position of the driver can be determined by combining the position information of the driver seat and the height information of the driver under the condition that the position of the driver seat is determined.

In another possible implementation, the position of the eyes of the driver is determined by calculation based on a depth map captured by a depth camera 40, and the vehicle includes the depth camera 40; for example, the depth camera 40 may be installed at a position facing the driver seat, and the depth image collected by the depth camera 40 includes the eyes of the driver and at least part of the in-vehicle components; the vehicle interior parts are fixed parts in the vehicle, such as seats, roofs or pillars and the like; wherein the depth Camera 40 can be a TOF (TOF Camera full resolution depth Camera) or other 3D imaging Camera, and a depth image including the driver and the in-vehicle component is captured by the depth Camera 40, and then the relative position relationship between the eyes of the driver and the in-vehicle component is determined by using the depth image; since the positional information of the in-vehicle components is not changed and can be determined according to parameters such as the model of the vehicle, the position of the eyes of the driver can be determined based on the depth image and the positional information of the in-vehicle components, and determining the position of the eyes of the driver by the depth camera 40 realizes improvement of the accuracy of determination of the position of the eyes of the driver, thereby improving the accuracy of adjustment of the shade device 20.

It should be noted that the position information of the present disclosure may be each coordinate information in a coordinate system, and the coordinate system may be a coordinate system that is unified by a vehicle and is constructed by using a certain point on the ground as an origin, and may also be a coordinate system built in the depth camera 40 or other coordinate systems such as world coordinates and the like, and it should be understood that the position information may also be identified by other manners besides the coordinate system, which is not limited in this embodiment.

After determining the driver eye position, a target elevation angle and a target relative azimuth angle range may be determined based on a relative relationship between the driver eyes and the vehicle window.

In one possible implementation, to determine a target elevation angle, the vehicle obtains a height difference of the driver's eyes from an upper edge of the window and a first horizontal distance of the upper edge of the window from the driver's eyes; the upper edge of the vehicle window is contacted with the vehicle roof; the window is the automobile interior spare of vehicle, consequently can obtain the position information of window according to the parameter of vehicle type, therefore the position information of window and the position information of driver's eyes have all been confirmed, then can confirm the difference in height of driver's eyes and the upper edge of window based on the position information of driver's eyes and the position information of window this moment to and the first horizontal distance of the upper edge of window and driver's eyes, according to the difference in height with the first horizontal distance carries out the operation of inverse trigonometric function, confirms the target angle.

For example, the upper edge of the window in this embodiment indicates the upper edge of the window directly above the eyes of the driver, please refer to fig. 4, d1 in fig. 4 is the height difference between the eyes of the driver and the upper edge of the window, d2 is the first horizontal distance between the upper edge of the window and the eyes of the driver, so the height difference and the first horizontal distance form a right triangle, and since the sun height angle is within the angle of arctan (d 1/d 2), the sun height angle can be irradiated to the eyes of the driver, so the formula Hmax = arctan (d 1/d 2), where Hmax represents the target height angle; it should be noted that the arctan function in this embodiment is only exemplary, and other inverse trigonometric functions may also be selected, and the distance between the eyes of the driver and other vehicle interior components may be obtained according to different inverse trigonometric functions to perform calculation, and other various functions may also be selected, and the corresponding distance parameter may be obtained adaptively, which is not limited in this embodiment.

For a common car body, three types of upright posts are arranged, namely a front post (A post), a middle post (B post) and a rear post (C post) from front to back, and for a car, the upright posts play a role of a door frame besides a supporting role; the vehicle window in the present disclosure refers to a front windshield as an example, and vehicle windows at other positions are similar according to specific situations. Since the front windshield is a main visual field of the driver and the driver's eye line needs to be kept oriented toward the front windshield, the driver's eyes may be irradiated with sunlight when the vehicle is irradiated with sunlight through the front windshield, and therefore, it is necessary to determine whether the driver's eyes are irradiated with solar light energy before controlling the shade device 20, and it is necessary to clarify the positions of the driver's eyes.

To determine a target relative azimuth range, the vehicle obtains a distance of the driver's eyes to the window, a second horizontal distance of the driver's eyes to a junction of the window and one of the vehicle a-pillars, and a third horizontal distance of the driver's eyes to a junction of the window and another of the vehicle a-pillars; and performing inverse trigonometric function operation according to the distance and the second horizontal distance, and performing inverse trigonometric function operation according to the distance and the third horizontal distance, and determining an upper limit and a lower limit in the relative azimuth range of the target. Illustratively, the inverse trigonometric function is an arctangent function.

In one example, referring to fig. 5A, fig. 5A is a top view of a vehicle, in a plane p where the eyes of the driver are located, the plane p intersects the window, so that the distance from the eyes of the driver to the window, i.e., the length of a perpendicular line between the eyes of the driver and the intersection of the plane p and the window, the distance d4 from the eyes of the driver to the window, and a second horizontal distance d3 from the eyes of the driver to the junction of the window and one of the a pillars of the vehicle; it can be seen that the distance d4 and the second horizontal distance d3 may form a right triangle, and the included angle α 1= actan (d 4/d 3) -90 ° may be calculated according to an inverse trigonometric function, where the included angle α 1 is used to indicate a range of azimuth angles of the sun limited to the left side of the driver's eyes and capable of irradiating the driver's eyes.

In another example, referring to fig. 5B, fig. 5B is a top view of a vehicle, in a plane p where the driver's eyes are located, a distance d4 from the driver's eyes to the window, and a third horizontal distance d5 from the driver's eyes to the junction of the window and another vehicle a-pillar; it can be seen that the distance d4 and the third horizontal distance d5 may form a right triangle, and an included angle α 2= actan (d 5/d 4) may be calculated according to an inverse trigonometric function, where the included angle α 2 is used to indicate a range of azimuth angles of the sun limited to the left side of the eyes of the driver, and capable of irradiating the eyes of the driver.

Further, referring to fig. 5A-5B, it is considered that when sunlight is irradiated from the left side of the vehicle head, the right eye of the driver is irradiated first; when the sun shines from the right side of the head of the vehicle, the left eye of the driver is shined first, wherein the left side and the right side correspond to the alpha 1 and the alpha 2; therefore, in order to improve the accuracy of the target relative azimuth angle range, the driver's eyes may be further distinguished from the left eye and the right eye to make a determination, that is, one of the vehicle a pillars in the process of determining α 1 may be a vehicle a pillar in the left front with respect to the driver, a distance d4 from the driver's right eye to the window, and a second horizontal distance d3 from the driver's right eye to the junction of the window and the vehicle a pillar in the left front, and α 1 is determined; in the determination α 2, the other vehicle a-pillar is the vehicle a-pillar at the front right with respect to the driver, the distance d4 from the left eye of the driver to the window, and the third horizontal distance d5 from the left eye of the driver to the joint of the vehicle a-pillar at the front right make the determination α 2, so that the accuracy of judging whether sunlight irradiates the eyes of the driver, that is, the accuracy of adjusting the shade device 20 is improved.

After the target elevation angle and the target relative azimuth angle corresponding to the eyes of the driver are determined, the shading device 20 adjustment procedure can then be performed by means of the target elevation angle and the target relative azimuth angle.

In one possible embodiment, the vehicle is equipped with a light sensor 50, and the light sensor 50 is used for detecting the illumination intensity of sunlight. Before the vehicle executes the steps S101-S104, whether the position of the vehicle has the sun is determined according to the illumination intensity detected by the light sensor 50, and the vehicle executes the steps S101-S104 under the condition that the light sensor 50 detects the existence of the sun; if no sunlight is detected at the light sensor 50, the steps S101 to S104 do not need to be executed, thereby contributing to saving of computational resources.

In another possible implementation, the vehicle has a networking function, the vehicle can acquire weather information of the position where the vehicle is located from a preset weather platform, and if the weather information is sunny, the vehicle executes the steps S101 to S104; if the weather information is cloudy, the steps S101-S104 are not required to be executed, thereby being beneficial to saving the operation resources.

In step 101, the vehicle may obtain current time information and current vehicle position information (e.g., longitude and latitude of the vehicle position) from relevant sensors (e.g., clock, satellite positioning module) in the vehicle, and then determine a solar altitude and a solar azimuth by using the time information and the vehicle position information in combination with the solar declination.

In some embodiments, considering that the slope influences the solar altitude in addition to the time information and the vehicle position information, when the vehicle runs in an environment with a slope, in the process of determining the solar altitude, the slope needs to be added for compensation, specifically, the solar altitude is subtracted from the solar altitude of the flat ground by a slope angle, wherein the slope angle is positive when the vehicle runs on an uphill slope and negative when the vehicle runs on a downhill slope, so that slope compensation is performed on the solar altitude in the uphill slope and the downhill slope, and an effect that when the solar altitude is compared and judged with a target altitude, an error due to the slope cannot occur is achieved.

Wherein the non-flat corresponding slope is determined according to at least one of the following information: the motion data collected by the inertial measurement unit of the vehicle, the ground inclination information identified from the image collected by the camera of the vehicle, the navigation information of the vehicle, or other ways in which the grade of the vehicle may be determined may be provided. The determination may also be made in other ways in the related art, and the present embodiment does not set any limitation to this.

In one example, the sun azimuth is the angle by which the sun is offset with respect to true north, and the relative azimuth of the sun to the vehicle is the angle by which the sun is offset with respect to the vehicle; the above α 1 and α 2 are used as the upper limit and the lower limit in the target relative azimuth range, that is, α 1 and α 2 are relative azimuths, so that the sun azimuth and the vehicle azimuth need to be obtained first, and the relative azimuth of the sun and the vehicle needs to be determined by calculation, so as to determine whether the relative azimuth falls between α 1 and α 2.

In determining the relative azimuth of the sun and the vehicle according to the vehicle orientation information and the sun azimuth in step S102, the orientation information is determined according to at least one of the following information: the vehicle is according to the running direction information of the navigation track, the azimuth information measured by a compass in the vehicle, or the steering information fed back by an electric power steering system in the vehicle. In one example, referring to fig. 5C, the vehicle may determine the heading information of the vehicle according to the angle between the driving direction of the vehicle and the north direction indicated in the navigation interface. For example, the heading information of the vehicle may be regarded as the heading information of the vehicle, and in one example, the heading information of the vehicle is expressed by a heading angle, for example, the heading information of the vehicle may determine that the vehicle head faces in a right-west direction, and the vehicle azimuth is-90 °; the process in determining the azimuth is therefore: firstly, acquiring a sun azimuth, then acquiring a vehicle azimuth according to the orientation information of the vehicle, and subtracting the vehicle azimuth from the sun azimuth to obtain a relative azimuth of the vehicle; for example, the vehicle is oriented in the straight west direction with the sun at 90 ° azimuth, the vehicle at-90 ° azimuth, and the vehicle at 90 ° - (-90 °) =180 ° relative azimuth.

In one example, the azimuth angle toward the north-plus direction is 0 °, the clockwise direction is a positive angle, and the counterclockwise direction is a negative angle. Referring to fig. 5D (N in fig. 5D indicates a true north direction), taking the window as an example, if the relative azimuth angle of the window is BS, the sun azimuth angle is a, and the azimuth angle of the window is B, then there is a relative azimuth angle BS = a-B.

After the relative azimuth angle is determined, the vehicle executes the step S103 to obtain a predetermined target elevation angle and a predetermined target relative azimuth angle range; that is, a predetermined target altitude Hmax and a target relative azimuth angle range (α 1 to α 2) are obtained, and then it is determined whether the solar altitude angle is smaller than the target altitude angle and the relative azimuth angle is within the target relative azimuth angle range, if the solar altitude angle is not smaller than the target altitude angle and the relative azimuth angle is not within the target relative azimuth angle range, the vehicle does not need to execute a step of adjusting the light shielding device 20; if the solar altitude is smaller than the target altitude and the relative azimuth is within the target relative azimuth range, the vehicle executes a step of adjusting the shade device 20; the following table 1 may be referred to as a basis for determining whether or not the adjustment of the shade device 20 is required.

TABLE 1

The shade device 20 of the present disclosure may include multiple shades 20 with different adjustment depending on the shade device 20.

In some embodiments, the shade device 20 includes a visor and a second drive motor for driving the visor; one end of the sun shield is fixed on the roof, the other end of the sun shield can rotate towards the direction of the window along the roof, so that sunlight rays injected from the window are shielded, and the rotation process is driven based on the second driving motor. Determining incident light capable of irradiating to a target position by the vehicle according to the positions of the eyes of the driver and the solar altitude; the target position is a position below the eyes of the driver; the closer the target position is to the eyes of the driver, the better, because the closer the target position is to the eyes of the driver, the sunlight irradiating the eyes of the driver can be shielded by the light shielding device 20, and the maximum visual field direction can be improved for the driver, but because the driver often moves slightly during driving or an error exists during determining the position of the eyes of the driver, the target position needs to be determined at a position below the eyes of the driver, and even if the error exists, the sunlight at the position of the eyes of the driver can be effectively shielded; referring to fig. 6, determining a target position of the sun visor according to an intersection point of the incident light and the movement track of the sun visor; driving the second drive motor to adjust the visor to the target position. The rotating track of the shading plate is rotated to the vehicle window from the vehicle roof, so that the visual field range of a driver, which is shaded by the shading plate, is gradually enlarged in the rotating process, the sun shield is adjusted to the position where the moving track of the sun shield is intersected with incident light for the first time, and the effect of keeping the driver in a larger visual field range while shading the incident light can be realized.

Since the setting of the target position is for eliminating an error in determining the driver's eye position, the distance between the target position and the driver's eye position may be set smaller when the error in determining the driver's eye position is smaller in order to keep the driver's visual field wide, and vice versa. Illustratively, the target location is less than 6 centimeters from the eyes of the driver.

In some embodiments, as can be seen from the above description, the position of the driver's eyes can be determined in two ways, one based on the height information of the driver and the other based on the depth image captured by the depth camera 40.

Because in the process of determining the eye position of the driver based on the height information of the driver, the height of the upper half of the body of the driver in a sitting posture, which is estimated by the proportional information corresponding to different heights, has a certain error, if the position information of the driver is estimated based on the height information of the driver, the target position needs to be arranged below the eye position of the driver, so that the error is counteracted to ensure that the incident light shielding the target position can ensure the incident light covering the eye position of the driver; when the distance between the positions of the eyes of the driver is determined based on the depth image, the position of the eyes of the driver determined in the mode is more accurate because the depth image is determined by the relative relation between the parts in the vehicle and the eyes of the driver, the error is smaller, and the target position can be arranged at the position closer to the position of the eyes of the driver.

That is, the distance between the target position and the driver's eye position determined based on the driver's height information is greater than the distance between the target position and the driver's eye position determined based on the depth image, for example, the distance between the target position and the driver's eye position determined based on the driver's height information is 5cm, and the distance between the target position and the driver's eye position determined based on the depth image is 3cm, so that the driver maintains the effect of a larger field of view while blocking incident light.

In other embodiments, referring to fig. 7, the shading device 20 includes a glass capable of changing light transmittance, which is disposed on the vehicle window, and includes a plurality of independently controlled regions divided in a horizontal direction; the shape and size of each region may be set as the case may be, for example, rectangular, circular, crescent, etc. The vehicle determines incident light capable of irradiating a target position according to the position of eyes of a driver and the solar angle; the target position is a position below the eyes of the driver; and according to the intersection point of the incident ray and the glass, reducing the light transmittance of one or more target areas between the intersection point and the roof, wherein the lower the light transmittance of the glass is, the stronger the light shielding capacity of the glass is, and vice versa. So as to play the effect of sheltering from the sunlight through the luminousness that changes glass, furthermore, can also carry out the luminousness of adaptation formula change glass in combination with the sunlight intensity that light sensor 50 gathered, for example, adjust the luminousness of glass to lower degree (for example, luminousness is 0% -10%) under the strong condition of sunlight to shelter from strong light, can adjust the luminousness of glass to moderate (for example, luminousness is 50% -60%) under the weak condition of sunlight, when having realized sheltering from the sunlight, still provide the effect of better field of vision scope for the driver.

It should be noted that the glass capable of changing light transmittance in the present disclosure may be disposed on the original window of the vehicle, and the two are mounted in a superposed manner; the whole vehicle window can be made of glass with changeable light transmittance.

In some embodiments, the vehicle may adjust the light shielding device 20 in real time according to the current sun illumination condition, and the time information in step S101 refers to the current time, and the vehicle position information refers to the current vehicle position. Further, when the sun altitude changes during the traveling of the vehicle, steps S101 to S104 are executed again.

For example, the vehicle may determine the solar altitude and the solar azimuth according to the current time and the current vehicle position in response to the change of the solar altitude, so that the vehicle may determine the solar altitude and the solar azimuth in time to adjust the shade device 20 when the light irradiated to the inside of the vehicle is changed.

In other embodiments, to further reduce the probability of sunlight striking the eyes of the driver, the vehicle may perform predictive adjustment, for example, the time information in step S101 may be a time indicating a preset time period from the current time, and the vehicle position information indicates a vehicle position after the preset time period determined according to the navigation trajectory of the vehicle and the planned vehicle speed. The preset time length can be set according to specific situations, such as 20s, 30s and the like; in the embodiment, the time information and the vehicle position after the preset time from the current time are acquired, whether the eyes of the driver are irradiated by the sunlight after the preset time is judged, and then the sun shield is controlled to play a role in eliminating the judgment process and the time difference caused by the time for adjusting the light shielding device 20, so that the eyes of the driver are not irradiated by the sunlight at any time; the mode of driving the sun shield can be determined according to the situation, and the position of the sun shield can be in the target position after the preset time.

For example, for the adjustment of the sun visor by the predictive adjustment process, the vehicle may drive the second drive motor after a preset time period to adjust the sun visor to the target position in a case where the sunlight may strike the eyes of the driver after the preset time period is determined.

For example, for the adjustment of the sun visor by the predictive adjustment process, in the case that the vehicle irradiates the eyes of the driver after the predetermined period of time, the rotation speed of the second driving motor may be determined according to the difference between the current position of the sun visor and the target position and the predetermined period of time, and the second driving motor may be driven from the current time according to the rotation speed so that the sun visor is adjusted to the target position after the predetermined period of time; the shading device 20 is gradually adjusted, so that the adjusting process of the shading device 20 is smoother, and the shading device 20 can continuously shade the changed sunlight based on the sunlight change in the form process, and the effect of improving the experience of a driver is realized.

For example, for the adjustment of the sunshade glass by the predictive adjustment process, the vehicle may predetermine an incident light ray that can be irradiated to the target location after a preset time period, and further determine an intersection point of the incident light ray and the glass, and then decrease the light transmittance of one or more target regions between the intersection point and the roof after the preset time period, the lower the light transmittance of the glass the greater its ability to block the light ray, and vice versa.

It should be understood that the solutions described in the above embodiments may be combined without conflict, and are not exemplified in the embodiments of the present disclosure.
