Referring to fig. 1-3, fig. 1 illustrates a method for adjusting a sun visor of a vehicle according to the present disclosure. The vehicle 100 is provided with a vehicle sun visor 10 fixed to a vehicle body 20, the vehicle sun visor 10 includes a controller 103, a sun visor 101 for blocking incident light, and an adjusting mechanism 102 for adjusting the sun visor 101, the adjusting mechanism 102 is in communication connection with the controller 103, the method is applied to the controller 103, and the method includes:
step S1: detecting whether the current illumination intensity exceeds an illumination intensity threshold value.
For example, the manner of detecting whether the current illumination intensity exceeds the illumination intensity threshold value may be to provide an illumination sensor at the front windshield 30 of the vehicle 100, and the illumination sensor is in communication connection with the controller 103. By setting the illumination intensity threshold of the illumination sensor, when the illumination sensor receives that the intensity of light entering the vehicle 100 through the front windshield 30 exceeds the illumination intensity threshold, the illumination sensor generates a corresponding sensing signal and sends the generated sensing signal to the controller 103, so that the controller 103 determines that the current illumination intensity exceeds the illumination intensity threshold. The illumination intensity threshold can be set according to needs, such as 600lx-1000 lx.
Step S2: and if the current illumination intensity exceeds the illumination intensity threshold value, acquiring light source direction information and driver head position information.
When the current illumination intensity exceeds the illumination intensity threshold, the controller 103 acquires light source direction information and driver head position information through other sensing devices provided in the vehicle 100.
In some embodiments, the acquiring light source direction information includes:
acquiring the incident angle of incident light;
and acquiring the light source direction information according to the incident angle.
The controller 103 is provided with a corresponding relationship of the incident angle α of the light source direction information, and the corresponding light source direction information can be calculated by acquiring the corresponding light incident angle α, so that the light source direction of the incident light is known according to the light source direction information, wherein the incident angle α of the light can be acquired by a solar altitude angle and a solar azimuth angle measuring device arranged on the vehicle 100.
For example, the angle of incidence α of the light rays cos γ cos ═ cos ∈ where h is the solar altitude, ε is the solar azimuth, γ -180- α. the solar altitude h, the solar azimuth e, may be obtained by one or more solar altitude and solar azimuth measurement devices mounted on the vehicle.
In some embodiments, the obtaining the head position information of the driver includes:
identifying the driver's head;
sending a ranging signal to the head of the driver;
acquiring a reflected ranging signal, wherein the reflected ranging signal is a ranging signal reflected by the head of the driver;
calculating a time difference between transmitting the ranging signal and receiving the reflected ranging signal;
and acquiring the head position information of the driver according to the time difference.
Illustratively, a camera device and a distance measuring device are arranged in the vehicle 100, and the controller 103 acquires image information of the driver through the camera device and recognizes the head of the driver from the image of the driver through an image recognition technology.
After recognizing the head of the driver, the controller 103 controls the distance measuring device to send a distance measuring signal to the head of the driver, and the distance measuring device calculates a time difference between the sending of the distance measuring signal and the receiving of the reflected distance measuring signal after receiving the reflected distance measuring signal reflected back after the distance measuring signal is irradiated to the head of the driver, so as to calculate the head position information of the driver, namely the position coordinate of the head of the driver under the space coordinate system, according to the sending direction of the distance measuring signal, the propagation speed of the distance measuring signal in a corresponding medium and the used time. The distance measuring signal may be an infrared signal or an ultrasonic signal, that is, the distance measuring device may be an infrared distance measuring device or an ultrasonic distance measuring device.
Step S3: and generating a driving signal according to the light source direction information and the head position information of the driver to drive the adjusting mechanism to adjust the sunshade baffle to shield incident light.
In some embodiments, the adjusting mechanism 102 includes a telescopic rod 1022 connected to the sunshade 101 and a rotating shaft 1021 connected to the telescopic rod 1022, and the generating a driving signal according to the light source direction information and the driver head position information to drive the adjusting mechanism 102 to adjust the sunshade 101 includes:
generating a driving signal according to the light source direction information and the driver head position information to drive the telescopic rod 1022 to stretch and contract and the rotating shaft 1021 to rotate so as to adjust the relative position and posture of the sunshade baffle 101 and the driver.
As shown in fig. 3, the controller 103 generates a driving signal according to the head position information of the driver to drive the telescopic rod 1022 to extend and retract so as to control the relative position between the sun visor 101 and the head of the driver, so that the sun visor 101 can block incident light for the driver.
As shown in fig. 4, the expansion and contraction direction of the expansion link 1022 is parallel to the front windshield 30.
When the telescopic rod 1022 is extended, the sunshade baffle 101 can be moved towards the head of a driver, so that the sunshade baffle 101 can shield incident light for the driver, when the telescopic rod 1022 is retracted, the sunshade baffle 101 can be moved towards the direction far away from the head of the driver, so that the sunshade baffle 101 is not required to shield the incident light for the driver, and the telescopic length H of the telescopic rod 1022 is set to meet the requirement, namely H & ltL & gtsin (90- β).
Wherein, L is the distance between flexible initial point A of telescopic link 1022 and the driver's head, and β is the contained angle that the flexible direction of telescopic link 1022 and the flexible initial point A of telescopic link 1022 and driver's head coordinate point are connected.
Knowing the coordinate of the initial expansion point a of the expansion link 1022 and the expansion direction of the expansion link 1022, the expansion length of the expansion link 1022 can be calculated only by calculating the coordinate point corresponding to the head position of the driver, i.e., the coordinate of point B.
Further, a driving signal is generated according to the light source direction information to drive the rotating shaft 1021 to rotate, so as to adjust the direction of the sunshade 101, that is, adjust the posture of the sunshade 101 relative to the head of the driver, thereby ensuring that the sunshade 101 shields incident light at a better angle, and providing a better driving environment for the driver.
For example, if the incident angle of the incident light is perpendicular to the sunshade 101, the sunshade 101 has the best effect of shielding the incident light, and the light incident angle is obtained by obtaining the light source direction, and the deflection angle of the sunshade 101 is adjusted according to the light source direction so that the sunshade 101 is perpendicular to the incident light.
In some embodiments, the method for adjusting a sun visor of a vehicle further includes:
and if the current illumination intensity exceeds the illumination intensity threshold value, the transparency of the sunshade baffle is adjusted according to the current illumination intensity.
Illustratively, an electrochromic material is disposed within the sunshade 101, and the controller 103 may change the transparency of the sunshade 101 by changing the electric field of the sunshade 101. When the illumination intensity exceeds a preset illumination intensity threshold, the controller 103 controls the electric field in the sunshade baffle 101 to change along with the change of the illumination intensity, so that the sunshade baffle 101 adjusts the transparency of the sunshade baffle 101 along with the illumination intensity to ensure that the light intensity penetrating through the sunshade baffle 101 is in a range without affecting the visual field of human eyes. If the highest value of the eye comfortable illumination intensity is that the illumination intensity of x incident light is y and the transparency of the sunshade baffle 101 is z, x is more than or equal to y x z, namely z is less than or equal to x/y.
In some embodiments, the method for adjusting a sun visor of a vehicle further includes:
if the current illumination intensity does not exceed the illumination intensity threshold, recording the duration time that the current illumination intensity does not exceed the illumination intensity threshold;
and if the duration time exceeds a time threshold, controlling the sunshade baffle to reset.
Illustratively, when the light sensor detects that the light intensity is smaller than the threshold value, the light sensor no longer sends a message to the controller 103, and the controller 103 sends a reset command to the adjusting mechanism 102 if the controller does not receive the message within a preset duration time, so as to restore the adjusting mechanism 101 to the initial state, wherein the duration time may be set as required, such as 10s, 15 s.
