Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.
In general, during daytime driving, a driver generally selects to wear sunglasses or block light by using a light blocking plate in order to prevent sunlight from directly irradiating the eyes and affecting the sight line. However, wearing sunglasses, once in a dark light environment such as at night and in a tunnel, a driver has no habit of wearing sunglasses, and wearing sunglasses may rather hinder normal driving of the driver. Secondly, when the sunglasses are worn manually under the condition of light irradiation, the potential safety hazard in the driving process can be increased.
The control method of the vehicle shade device of the embodiment of the application comprises the following steps:
01: detecting sun ray information;
02: and under the condition that the driver is determined to be in a direct sunlight state according to the sunlight information, generating a color change signal to control the shading device to change the color.
The present application further provides a vehicle comprising a memory and a processor. The storage is stored with a computer program, and the processor is used for detecting the sun ray information; and the color changing signal is used for generating a color changing signal to control the shading device to change the color under the condition that the driver is determined to be in the direct sunlight state according to the sunlight information.
Specifically, the shade device may be a front windshield of the vehicle, or a variable color light transmission device installed at a position between the driver and the windshield, the variable color light transmission device shielding the face of the driver. The shading device may also be a wearable device, such as variable colour glasses.
Referring to fig. 2, in some embodiments, a whole or part of the windshield may be formed as a shade or the shade may be installed between the driver and the windshield. In other embodiments, the shade may be glasses or a mask. Wherein the light screening device may be made of electrochromic glass. The electrochromic glass can generate a stable and reversible color change phenomenon under the condition of an external electric field, and can be adjusted to different levels of light transmittance under the action of different voltages. For example, after the electrochromic glass receives a color-changing signal sent by a vehicle, the electrochromic glass is changed from transparent to dark color, and the light transmittance is reduced to shield the sun.
Referring to fig. 3, the sunlight information may include the intensity of the sunlight and the distance between the sun and the equipment on the vehicle. Such as the distance of the sun from the camera of the vehicle's rearview mirror and the distance of the sun from the driver monitoring system. Wherein the driver monitoring system may be mounted on the steering wheel or on the a-pillar of the vehicle.
It is understood that after determining the current geographic location information of the vehicle, the current season, and the current time, the distance between the sun and the vehicle device may also be determined, and the distance may be obtained by querying the relevant platform or application. Because the sun is far from the vehicle equipment, the distance between the sun and the different equipment on the vehicle can be made approximately equal. For example, the distance of the sun from the trinocular camera at the vehicle interior mirror and the distance of the sun from the driver monitoring system may be considered to be equal. The intensity of the solar ray can be obtained by a device with a light sensor, such as a sunlight sensor or a camera on the vehicle.
The distance between the devices of the vehicle is fixedly measurable. For example, a trinocular camera at the interior rearview mirror and a driver monitoring system fix the rear available measuring instrument to acquire the distance between the two. The distance between the devices in the vehicle can be calibrated before the vehicle leaves a factory, and is prestored in a memory of the vehicle for calling when in use.
The driver monitoring system can identify the positions of the eyes of the driver and can measure the distance and the angle between the positions of the eyes and the equipment on the vehicle. For example, the driver monitoring system may measure the distance of the eye position from the driver monitoring system, and the angle of the eye and the trinocular camera at the driver monitoring system and the interior rearview mirror. Thereby calculating the angle between the three-eye camera at the position of the sun and the inner rearview mirror and the position of the eyes of the driver.
The driver is in the direct sunlight state means that sunlight rays directly irradiate the eyes of the driver, and understandably, when the eyes of the driver are directly irradiated by the sunlight, the hidden danger of driving safety can be caused because the driver cannot see the road condition clearly.
Referring to fig. 2-4, in one example, when a driver drives a vehicle during the day, the distance between the sun and the trinocular camera at the inside rearview mirror of the vehicle and the distance between the sun and the driver monitoring system may be determined, respectively, in combination with information about the current geographical location of the vehicle, the current season, and the current time. Then, the distance between the three-eye camera at the position of the inner rearview mirror and the driver monitoring system which is prestored is called. Then, the vehicle controls the driver monitoring system to recognize the positions of the human eyes, determines the distance between the positions of the human eyes and the driver monitoring system, and the angles between the driver monitoring system and the trinocular camera and the human eyes at the position of the inner rearview mirror. And finally, calculating the angle of an included angle delta formed by the sun, a trinocular camera at the inner rearview mirror and the positions of the eyes of the driver through the acquired distance and angle, when the delta is smaller than or equal to a preset angle threshold value, such as 180 degrees, the vehicle determines that the driver is in a direct sunlight state, generates a color change signal and sends the color change signal to the shading device, and the shading device changes the color to shade the sunlight after receiving the signal. When the angle δ is larger than a preset angle threshold, it can be considered that the driver is not in the direct sunlight state for the moment, and the shading device keeps the current state unchanged.
The preset angle threshold may be set according to actual conditions and subjective feelings of the user, and is not limited herein.
In this way, the control method of the vehicle shade device and the vehicle according to the embodiment of the present application determine the irradiation state of the solar ray according to the solar ray information, thereby determining whether the driver is directly irradiated by the solar ray. And under the condition that the solar rays directly irradiate the eyes of the driver, the shading device is controlled to change the color of the driver so as to shade the solar rays. The driver can clearly see the road environment when driving in the daytime, and meanwhile, the potential safety hazard possibly caused by manually adjusting the shading device in the driving process is effectively avoided.
Referring to FIG. 5, in some embodiments, the solar ray information includes intensity information and angle information, and step 02 includes
020: and under the condition that the intensity value of the solar ray is greater than the intensity value threshold value, generating a color change signal and sending the color change signal to the shading device to control the shading device to change the color under the condition that the driver is in a direct sunlight state according to the angle information of the solar ray.
In some embodiments, the processor is configured to generate a color change signal and send the color change signal to the shade device to control the shade device to change color if the driver is determined to be in a direct sunlight state according to the angle information of the solar rays when the intensity value of the solar rays is greater than the intensity value threshold.
Specifically, the intensity value of the solar ray intensity may be detected by a sun sensor or a camera disposed on the vehicle. When the intensity value of the solar light is greater than the preset intensity threshold value, the intensity of the solar light is considered to stimulate the eyes of the driver and prevent the driver from driving the vehicle. Under the condition, the angle of an included angle delta formed by the sun, a trinocular camera at the position of the inner rearview mirror and the positions of the eyes of the driver is further detected, when the delta is smaller than or equal to a preset angle threshold value, the driver can be considered to be in a direct sunlight state, the vehicle generates a color change signal and sends the color change signal to the shading device, and the shading device changes the color after receiving the signal and shades the sunlight.
It should be understood that the trinocular camera is generally installed at the inside rear-view mirror, i.e. the center of the windshield, when the vehicle leaves the factory, and the distance between the trinocular camera and other parts in the vehicle is also easy to measure, so that the trinocular camera is used as a positioning point to facilitate relevant calculation. In other embodiments, any point along the windshield may be used as a calculated positioning point, which is not limited herein.
The preset intensity threshold may be set according to an actual demand or a subjective feeling of a driver, for example, 700lux, 800lux, 900lux, and the like, and is not limited herein.
In this way, the sunlight information includes the intensity information and the angle information of the sunlight, and when the intensity value of the sunlight is detected to be higher than the threshold value of the intensity value, the sunlight intensity can be considered to stimulate the eyes of the driver and prevent the driver from driving the vehicle. In this case, it is determined whether the driver is in a direct sunlight state based on the angle information of the solar ray with the vehicle apparatus. And under the condition of being in a direct sunlight state, controlling the shading device to change color.

In some embodiments, the processor is configured to obtain a first distance from the sun to a first camera of the vehicle, the first camera mounted at an interior rearview mirror of the vehicle; and for obtaining a second distance from the sun to a driver monitoring system of the vehicle; the first camera is used for acquiring a first distance from the driver monitoring system to the first camera; and the first camera is used for determining a first angle formed by the first camera, the sun and the driver monitoring system according to the first distance, the second distance and the third distance.
Referring to fig. 7, to determine the angle of the included angle δ formed by the sun, the trinocular camera at the inside rear-view mirror and the position of the eyes of the driver. The first angle, that is, the angle of the included angle β formed by the trinocular camera at the interior rear view mirror and the sun and the driver monitoring system, and the third angle, that is, the angle of the included angle γ formed by the trinocular camera at the interior rear view mirror and the human eyes and the monitoring system, may be calculated first. The angle of β and the angle of γ are then added to obtain the angle of δ. The position relationship among the sun, the devices on the vehicle, and the positions of the human eyes is simplified into a schematic diagram as shown in fig. 7, where the positions of the human eyes are point a, the sun is point D, the trinocular camera mounted on the inside rear view mirror of the vehicle is point B, and the driver monitoring system is point C, and as described above, the first distance, that is, the distance BD from the sun D to the trinocular camera B on the inside rear view mirror, and the second distance, that is, the distance CD from the sun D to the driver monitoring system C can be determined from the relevant platform or application program according to the information such as the current geographical position information, the current season, and the current time of the vehicle. The third distance, i.e. the distance BC from the trinocular camera B at the interior mirror to the driver monitoring system C, can be determined by the driver monitoring system. Further, under the condition that the distances of the BD, the CD and the BC are known, the angle of the beta can be calculated according to the cosine law. The specific formula is as follows:
therefore, the angle of the included angle formed by the first camera, the sun and the driver monitoring system is determined through the first distance from the sun to the first camera of the vehicle interior rearview mirror, the second distance from the sun to the driver monitoring system and the third distance from the first camera to the driver monitoring system, and the angle is used for judging the irradiation state of sunlight.
Referring to fig. 8, in some embodiments, step 020 includes:
0205: acquiring a fourth distance from eyes of the driver to the driver monitoring system;
0206: acquiring a second angle formed by the driver monitoring system, the first camera and the human eyes;
0207: and determining a fifth distance from the human eyes to the first camera according to the third distance, the fourth distance and the second angle.
In some embodiments, the processor is configured to obtain a fourth distance from the eyes of the driver to the driver monitoring system; the first camera is used for acquiring a first angle formed by the driver monitoring system and the human eyes; and the second distance determining unit is used for determining a fifth distance from the human eye to the first camera according to the third distance, the fourth distance and the second angle.

The second angle, that is, the angle of the included angle θ formed by the driver monitoring system C and the trinocular camera B and the human eye a at the position of the vehicle interior rearview mirror, can be determined by the driver monitoring system. Further, under the condition that the AC distance, the angle θ and the BC distance are known, the distance AB can be calculated according to the cosine law, and the specific formula is as follows:
therefore, the fifth distance from the human eyes to the first camera can be determined by acquiring the fourth distance from the human eyes of the driver to the driver monitoring system, the third distance from the driver monitoring system to the first camera and the second angle of the included angle formed by the driver monitoring system, the first camera and the human eyes, and the distance is used for judging the irradiation state of sunlight.

0208: and determining a third angle formed by the first camera, the human eyes and the monitoring system according to the third distance, the fourth distance and the fifth distance.
In some embodiments, the processor is configured to determine a third angle formed by the first camera with the human eye and the monitoring system according to the third distance, the fourth distance, and the fifth distance.
Referring to fig. 7, specifically, under the condition that the AB distance, the AC distance, and the BC distance are known, a third angle, that is, an angle of an included angle γ formed by the trinocular camera B at the inside rear view mirror, the human eye a, and the driver monitoring system C, can be obtained according to the cosine law, and the specific formula is as follows:
therefore, a third angle of an included angle formed by the first camera, the human eyes and the driver monitoring system can be determined through a third distance from the driver monitoring system to the first camera, a fourth distance from the human eyes to the driver monitoring system and a fifth distance from the human eyes to the first camera, and the angle is used for judging the irradiation state of sunlight.
Referring to fig. 10, in some embodiments, step 020 includes:
0209: in the case where the sum of the first angle and the third angle is less than or equal to the angle threshold value, it is determined that the driver is in the direct sunlight state.
In some embodiments, the processor is configured to determine that the driver is in direct sunlight if the sum of the first angle and the third angle is less than or equal to an angle threshold.
Specifically, the angle of the included angle β formed by the trinocular camera B at the interior rear view mirror and the sun D and the driver monitoring system C and the angle of the included angle γ formed by the trinocular camera B at the interior rear view mirror and the human eye a and the driver monitoring system C are added together to obtain the angle of the included angle δ formed by the sun D and the trinocular camera B at the interior rear view mirror and the human eye a, namely:
δ＝β+γ
when the delta is smaller than or equal to the preset angle threshold value, the eyes of the driver can be determined to be directly irradiated by the sunlight rays.
Thus, the sum of the first angle and the third angle can be used for judging the irradiation state of sunlight on human eyes. When the sum of the first angle and the third angle is less than or equal to the angle threshold, it may be determined that the eyes of the driver are directly illuminated by sunlight.
Referring to fig. 11, in some embodiments, step 02 includes:

Specifically, the shading device of the embodiment of the present application is a color-variable wearable device, and the color-variable wearable device may be glasses, a mask, or the like. The color-changeable wearable device is connected with the vehicle in a communication mode such as Bluetooth. When the vehicle determines that the sunlight shines directly on the eyes of the driver according to the information of the sunlight, the vehicle generates a color change signal and sends the color change signal to the color-changeable wearing device, and the shading part of the color-changeable wearing device changes from light color to dark color.
In this way, the shading device can be a color-variable wearable device in communication connection with the vehicle, and when the driver is determined to be in direct sunlight, the generated color-variable signal is sent to the wearable device, and the wearable device changes color to shade the sunlight after receiving the signal.
