[0031] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides a vehicle lighting control method based on external environment perception, which is used to solve the problem in the prior art that reflections formed by light sources inside the vehicle affect the driving safety of the vehicle.

[0033] See also Figure 1 , Figure 1 This is a first flow chart of a vehicle lighting control method based on external environment perception provided by an embodiment of the present invention.

[0034] S100, obtaining vehicle information, and calculating the horizontal position of the driving position according to the vehicle information; obtaining the first position of each first ambient light sensor, and calculating the distance between each first ambient light sensor and the horizontal position of the driving position according to the first position, to obtain a plurality of first intervals; substituting the first horizontality and each first interval into a driving position brightness model, wherein the driving position brightness model is specifically:

[0035]

[0036] in, is the brightness of the driving position, E n and E m are the brightness of the nth and mth first ambient light sensors, respectively, x n is the distance between the nth first ambient light sensor and the horizontal position of the driving position, y nm is the distance between the light sources corresponding to the nth and mth first ambient light sensors and the horizontal position of the driving position, a is the number of first ambient light sensors, and α is the external light correction parameter;

[0037] It should be noted that the first ambient light sensor is installed on the outside of the front windshield of the vehicle, or close to the inside of the glass facing outward, for sensing the external ambient light of the vehicle; there are multiple first ambient light sensors, which are arranged for installation. In this embodiment, only the impact of the horizontal direction difference of light on the driving position is considered, and the impact of the vertical direction difference of light is ignored. The position of each first ambient light sensor can be calculated during installation, and the first position can be obtained by only measuring the distance between the sensor and the edges of the front windshield on both sides. The ambient light sensor is a photoelectric sensor, which converts the light intensity into an electrical signal for analysis. The rain sensor commonly installed on the vehicle can be used as the first ambient light sensor, and the rain sensor can judge the size of the rain by the light scattering situation;

[0038] The vehicle information is specifically the model parameters of the vehicle, and the width of the front windshield of the vehicle and the left and right steering conditions of the vehicle can be obtained. According to the left steering or right steering condition of the vehicle, the position of the driver when observing the road conditions at the driving seat can be calculated in combination with the width of the front windshield. The main and co-driver seats of the vehicle are generally symmetrically arranged, and the driver is in the middle of the driving seat. Therefore, the horizontal position of the driving seat can be set at a position of 1 / 4 or 3 / 4 below the width of the front windshield, and then the distance between the sensor and the horizontal position of the driving seat is calculated according to the first position of each first ambient light sensor to obtain the first spacing;

[0039] The brightness of light as it travels is inversely proportional to the square of the distance it travels, see Figure 2, the solid line in the figure represents the front windshield, and the hollow circle intersecting the three dotted lines is the location of the simulated light source. The brightness values ​​detected at every two first ambient light sensors can calculate a light source located directly in front of the driver's seat, which is equivalent to the light source irradiating the front windshield, and the distance between the light source directly in front of the driver's seat and the front windshield is obtained according to the driver's seat brightness model; there is an error in the light source calculated by each group of first ambient light sensors, so after traversing all simulated light sources and taking the average value, the actual brightness of the driver's seat can be obtained under the current external environment perceived lighting conditions; the first ambient light sensor is generally installed close to the front windshield, and its detection light is directional, and the main detection light direction is perpendicular to the windshield surface, while the front windshield is generally tilted, and the main ambient light during vehicle driving is street lights. Or diffusely reflected light from above other vehicles. There is less light directly hitting the front windshield on the road. The direct light is mainly from the headlights of oncoming vehicles. In this case, the brightness of the direct light is obvious in the driver's field of vision, and the reflection of the glass produced by the lights inside the car has little effect on the driver's judgment of the road conditions. Therefore, it is not considered, and the light component of the direct light in the inclined direction; a driving seat brightness model can be established based on the situation of sensors installed on the vehicle for real-time data monitoring in subsequent steps; when the first ambient light sensor is set on the outside of the glass, the external light correction parameters can be set according to the glass material or the film on the outside of the glass. When the first ambient light sensor is set on the inside of the glass, the external light correction parameters can be set according to the film on the inside of the glass. The glass material and the film will weaken the light, and the correction parameters are generally less than 1.

[0040] S200, real-time monitoring of the brightness of each first ambient light sensor and the second ambient light sensor, substituting the brightness value of each first ambient light sensor into the driving position brightness model to obtain the driving position brightness; substituting the driving position brightness and the second ambient light sensor brightness into the brightness difference calculation model, if the model is satisfied, obtaining the brightness difference in the brightness difference calculation model, and reducing the absolute value of the brightness difference of the interior light brightness, the brightness difference calculation model is specifically:

[0041]

[0042] Among them, ΔE is the brightness difference, β is the internal lighting correction parameter, E0 is the interior brightness of the vehicle, and E is the safety brightness difference.

[0043] It should be noted that the second ambient light sensor is installed on the inside of the front windshield of the vehicle to detect the lighting conditions inside the vehicle. The second ambient light sensor can be set on the top of the vehicle, which can reduce the interference error of the second ambient light sensor inside the vehicle detecting the light outside the vehicle. The light inside the vehicle is generally generated by the ambient light, the vehicle system display and the interior lighting. The light emitted by these light sources is diffuse reflection. In the case of diffuse reflection, the brightness of the light imaged on the front windshield is regarded as consistent with the brightness of the light received by the top of the vehicle.

[0044] During vehicle driving, the first ambient light sensor and the second ambient light sensor are used to monitor the brightness value in real time. After substituting the brightness values ​​of each first ambient light sensor into the driving position brightness model, the driving position brightness obtained is the brightness of the outside environment seen by the driver through the front windshield, and the interior brightness of the vehicle monitored by the second ambient light sensor is corrected by the internal lighting correction parameter to obtain the brightness of the reflection inside the vehicle seen by the driver on the front windshield. The internal lighting correction parameter can be set according to the film condition inside the front windshield. When driving at night, the brightness of the diffuse reflection of the external ambient light of the vehicle into the vehicle can be ignored; the brightness difference after subtracting the two brightness values ​​is the perception value used by the driver to distinguish the imaging, that is, the driver will distinguish whether the image on the front windshield is inside or outside the vehicle according to the clarity or brightness of the imaging, so the safety The full brightness difference is set according to the minimum brightness difference perceived by the human eye, that is, the minimum brightness at which the human eye can distinguish the difference between the reflection inside the car and the image outside the car, or the difference is increased according to safety requirements. If the brightness difference calculated by the brightness difference calculation model is less than zero, it means that the light inside the current vehicle environment is brighter. The reflection imaging at the front windshield will cause the driver to need to distinguish whether it is the inside or outside environment based on the actual shape and object of the imaging, affecting the vehicle driving safety. At this time, it is necessary to control the vehicle lights. The internal light sources of the vehicle are connected to the Internet of Vehicles. When it is recognized that the lights need to be controlled, the brightness of the internal light sources of the vehicle can be reduced according to the size of the brightness difference, such as turning off the ambient light, reducing the brightness of the screen display and lighting inside the car, so as to improve driving safety and the driver's driving experience.

[0045] In this embodiment, the brightness of the external light received at the driving position is analyzed by the brightness detected by multiple first ambient light sensors, and the external brightness is compared with the internal brightness monitored by the second ambient light sensor. When the brightness difference is less than the safety brightness difference, it is judged that the interior of the vehicle is brighter and the reflection will affect the driver's observation of the road condition. Then, the vehicle lights are adjusted according to the brightness difference, thereby ensuring the safety of the vehicle and a good driving experience for the driver.

[0046] The above is a detailed description of the first embodiment of the vehicle lighting control method based on external environment perception provided by the present application. The following is a detailed description of the second embodiment of the vehicle lighting control method based on external environment perception provided by the present application.

[0047] In this embodiment, a vehicle lighting control method based on external environment perception is further provided. In the aforementioned step S200, after the real-time monitoring of the brightness of each of the first ambient light sensors and the second ambient light sensors, it also includes: obtaining the brightness of the third ambient light sensor, subtracting the brightness of the third ambient light sensor with a preset ratio parameter from the brightness of the second ambient light sensor, and correcting the brightness of the second ambient light sensor.

[0048] It should be noted that the third ambient light sensor is arranged at the top edge of the vehicle, close to the inside of the vehicle's side windshield, and directed toward the outside of the glass. It is used to detect the influence of external ambient light from the vehicle's side windshield on the second ambient light sensor in the vehicle. Because the vehicle's side windshield is basically set vertically, the external ambient light interference monitored by the third ambient light sensor is generally horizontal light, which directly affects the second ambient light sensor and has little effect on the imaging of the light source in the vehicle on the front windshield. Therefore, the brightness of the external ambient light interference monitored by the third ambient light sensor can be subtracted from the brightness monitored by the second ambient light sensor according to the preset proportional parameter, which can increase the calculation accuracy of the brightness difference in the above steps; the specific preset proportional parameter can be set according to the light coherent superposition formula, or an empirical value can be used.

[0049] Furthermore, in the aforementioned step S200, after the real-time monitoring of the brightness of each first ambient light sensor and the second ambient light sensor, it also includes: if the average brightness of each first ambient light sensor is greater than the brightness threshold, sending a vehicle interior light release command to the Internet of Vehicles and turning off the second ambient light sensor; when the vehicle is driving during the day or in a well-lit environment, the brightness difference of the interior light source is much greater than zero even when the brightness is adjusted to the maximum value, or the diffuse reflection of the external ambient light through the glass in the car is sufficient for the identification and movement of the people in the car, there is no need to control the interior light brightness in the Internet of Vehicles, and no matter how the interior light is adjusted, it will not affect the observation of the driver in the driving seat. The second ambient light sensor can be turned off, and the second ambient light sensor can be turned on when the average brightness of each first ambient light sensor is less than the brightness threshold; the brightness threshold is set according to the second link light sensor detection value when the brightness of the interior light source of the vehicle is set to the maximum plus the safety brightness difference.
