[0021] The vehicle window is generally transparent to light. When the light penetrates the vehicle window and irradiates into the vehicle, the temperature in the vehicle will rise, thereby affecting the comfort in the vehicle.

[0022] Currently, the light intensity entering the vehicle is generally adjusted by manually operating the sunshade or adjusting the light transmittance of the vehicle window glass to alleviate the influence of light on the temperature in the vehicle. However, this adjustment method requires the driver to operate in the process of driving, which increases the risk of driving. At the same time, this manual adjustment completely depends on the active operation of the user, which is inconvenient to use.

[0023] To solve the above problems, the embodiments of the present application provide a vehicle window adjustment method, device, equipment, vehicle and computer program product, which can automatically determine the target vehicle window to be adjusted based on the light energy generated by the irradiation of the environment light on the interior of the vehicle, and automatically adjust the light transmittance of the target vehicle window, without the need for manual operation of the user, which is more convenient.

[0024] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0025] The embodiments of the present application provide a vehicle window adjustment method. The method can be executed by an electronic device, which can be any device with data and instruction processing functions, such as notebook computers, tablet computers, desktop computers, mobile devices, car device, etc. various types of user terminals or any combination of two or more of these electronic devices, or a server. Referring to Figure 1 The method includes: S101, determining the light energy generated by the irradiation of the environment light on the interior of the vehicle.

[0026] The above light energy refers to the energy carried by light as an electromagnetic wave, which is related to the intensity, irradiation area and irradiation time of light. After the environmental light penetrates the vehicle window and irradiates into the vehicle interior, it will generate light energy in the vehicle interior, causing the temperature in the vehicle interior to rise.

[0027] The ambient light refers to all visible light acting on the vehicle in the surrounding environment outside the vehicle, including natural light sources such as sunlight, and artificial light sources such as street lamps and lights of other vehicles. In a specific embodiment, the sunlight has the most significant impact on the light energy in the vehicle interior, and the sunlight is taken as the ambient light in the embodiment.

[0028] In the embodiment of the present application, the light energy generated by the illumination of the environment in the vehicle interior is determined first.

[0029] In some embodiments, a light sensor can be installed in the vehicle, the light intensity is measured by the light sensor, and then the product of the light intensity and the light area is calculated, and the product of the light intensity and the light area is taken as the light energy generated by the illumination of the environment in the vehicle interior.

[0030] The light sensor can be uniformly arranged on the surface of the vehicle window glass or in the vehicle interior, the light intensity at different positions in the vehicle is directly measured by the light sensor, and the light energy generated by the illumination of the environment in the vehicle interior is more accurately identified by comprehensive analysis of the data of the multiple light sensors. For example, the average of the light intensities detected by the multiple light sensors can be calculated as the light intensity in the vehicle interior, and then the product of the light intensity in the vehicle interior and the light area is calculated, and the product of the light intensity in the vehicle interior and the light area is taken as the light energy generated by the illumination of the environment in the vehicle interior.

[0031] S102, if the detected light energy is in the preset energy range, a target window is determined from the windows of the vehicle according to the illumination angle of the ambient light, and the light transmittance of the target window is adjusted.

[0032] The detected light energy is compared with the preset energy range, and if the detected light energy is in the preset energy range, it indicates that the light energy generated by the illumination of the environment in the vehicle interior is too large, resulting in too high temperature in the vehicle, or the light energy generated by the illumination of the environment in the vehicle interior is too small, resulting in too low temperature in the vehicle, affecting the comfort of the people in the vehicle interior, and the light transmittance of the target window needs to be adjusted according to the illumination angle of the ambient light.

[0033] The target window refers to the window through which the ambient light enters.

[0034] In some embodiments, the ambient light in the daytime refers to sunlight. For example, when a vehicle is driving eastward along an east-west road at 10 o'clock in the morning, the sun is located at the east side of the sky, and the sunlight will directly penetrate the left side window of the vehicle to enter the vehicle. In this case, the left side window is the window through which the ambient light enters, i.e., the target window. For another example, when the vehicle is driving northward along a north-south road at 6 o'clock in the afternoon, the sun is located at the west side of the sky and is in a slanting state, and the sunlight will penetrate the right side window and the rear windshield of the vehicle to enter the vehicle. In this case, the right side window and the rear windshield jointly constitute the target window.

[0035] In yet some embodiments, in the absence of sunlight at night, the ambient light can include the night road lighting. For example, when the vehicle is driving along a city road at night, the street lamp on the right side of the road continuously emits light, and the light will penetrate the right side window of the vehicle to enter the vehicle. In this case, the right side window is the target window.

[0036] Generally, if the light energy generated by the illumination of the interior of the vehicle by the ambient light is too large to cause the temperature in the vehicle to be too high, it is necessary to reduce the light energy in the interior of the vehicle to reduce the temperature in the interior of the vehicle. An effective approach is to determine the target window from the windows of the vehicle according to the illumination angle of the ambient light, wherein the target window includes the window through which the ambient light enters, and to reduce the light transmittance of the target window to reduce the ambient light entering the interior of the vehicle through the target window, thereby achieving the purpose of reducing the light energy generated by the illumination of the interior of the vehicle by the ambient light, and finally reducing the temperature in the interior of the vehicle. At the same time, the light transmittance of the other windows of the vehicle except the target window is not adjusted, and the external scattered light can enter the interior of the vehicle through the other windows, thereby avoiding affecting the lighting effect of the vehicle to the greatest extent under the premise of reducing the temperature in the interior of the vehicle.

[0037] For example, if the light energy generated by the illumination of the interior of the vehicle by the ambient light is too large to cause the temperature in the vehicle to be too high, and it is determined that the window on the driver's side is the window through which the ambient light enters, the light transmittance of the window on the driver's side can be reduced to block the ambient light, thereby reducing the light energy generated by the illumination of the interior of the vehicle by the ambient light and reducing the temperature in the interior of the vehicle.

[0038] Generally, if the light energy generated by the illumination of the interior of the vehicle by the ambient light is too small to cause the temperature in the vehicle to be too low, it is necessary to increase the light energy in the interior of the vehicle to increase the temperature in the interior of the vehicle. An effective approach is to determine the target window from the windows of the vehicle according to the illumination angle of the ambient light, wherein the target window includes the window through which the ambient light enters, and to increase the light transmittance of the target window to increase the ambient light entering the interior of the vehicle through the target window, thereby achieving the purpose of increasing the light energy generated by the illumination of the interior of the vehicle by the ambient light, and finally increasing the temperature in the interior of the vehicle.

[0039] It should be noted that in this case, the target window can include other windows in addition to the window through which the ambient light enters, and the transmittance of all windows of the vehicle is increased to rapidly increase the ambient light entering the vehicle interior through the target window, and then rapidly increase the temperature of the vehicle interior.

[0040] For example, if the light energy generated by the illumination of the interior of the vehicle by the ambient light is too small to cause the temperature of the vehicle interior to be too low, and it is determined that the window on the driver's side is the window through which the ambient light enters, the light transmittance of the window on the driver's side can be increased to transmit the ambient light, thereby increasing the light energy generated by the illumination of the interior of the vehicle by the ambient light, and increasing the temperature of the vehicle interior. In this case, the light transmittance of other windows can also be increased at the same time to rapidly increase the temperature of the vehicle interior.

[0041] The above-mentioned preset energy range can be set according to actual conditions, and the embodiment is not limited.

[0042] It should be noted that the window of the embodiment includes an electrochromic glass or other glass with adjustable light transmittance. After generating the instruction for adjusting the light transmittance of the window, the driving circuit of the window can be controlled to change the light transmittance of the window glass.

[0043] In the above embodiment, the light energy generated by the illumination of the interior of the vehicle by the ambient light can be determined, and in the case where the light energy is detected to be within the preset energy range, the target window is determined from the windows of the vehicle according to the illumination angle of the ambient light, and the light transmittance of the target window is adjusted. By such a setting, the target window that needs to be adjusted can be automatically determined based on the light energy generated by the illumination of the interior of the vehicle by the ambient light, and the light transmittance of the target window is automatically adjusted, thereby adjusting the intensity of the light entering the vehicle interior, and relieving the influence of the light on the temperature of the vehicle interior. This process does not require manual operation by the user, and is more convenient.

[0044] In an optional embodiment, the step of the above embodiment of detecting that the light energy is within the preset energy range, determining the target window from the windows of the vehicle according to the illumination angle of the ambient light, and adjusting the light transmittance of the target window can specifically include the following steps: If it is detected that the light energy is greater than the first preset energy threshold, the target window is determined from the windows of the vehicle according to the illumination angle of the ambient light, and the light transmittance of the target window is reduced.

[0045] Specifically, if the detected light energy is greater than the first preset energy threshold, it indicates that the light energy generated by the interior of the vehicle being irradiated by the ambient light is too large, resulting in the temperature inside the vehicle being too high, and the target window is determined from the windows of the vehicle according to the irradiation angle of the ambient light, wherein the target window includes the window through which the ambient light enters, and the light transmittance of the target window is reduced to reduce the ambient light entering the interior of the vehicle through the target window, thereby achieving the purpose of reducing the light energy generated by the interior of the vehicle being irradiated by the ambient light, and finally reducing the temperature inside the vehicle.

[0046] The first preset energy threshold described above can be set according to actual conditions, and the embodiment is not limited.

[0047] In the above embodiment, the light transmittance of the window through which the ambient light enters can be automatically reduced when it is detected that the light energy is greater than the first preset energy threshold, thereby achieving the purpose of reducing the temperature inside the vehicle, without the need for manual operation by the user, and the convenience is stronger.

[0048] At the same time, the light transmittance of the other windows of the vehicle other than the target window is not adjusted, and the external scattered light can still enter the interior of the vehicle through the other windows, thereby avoiding the influence on the lighting effect of the vehicle to the greatest extent under the premise of reducing the temperature inside the vehicle.

[0049] In an optional embodiment, if the light energy is detected to be within the preset energy range in the steps of the above embodiment, the target window is determined from the windows of the vehicle according to the irradiation angle of the ambient light, and the light transmittance of the target window is adjusted, which can specifically include the following steps: If the detected light energy is less than the second preset energy threshold, the target window is determined from the windows of the vehicle according to the irradiation angle of the ambient light, and the light transmittance of the target window is increased.

[0050] Specifically, if the detected light energy is less than the second preset energy threshold, it indicates that the light energy generated by the interior of the vehicle being irradiated by the ambient light is too small, resulting in the temperature inside the vehicle being too low, and the target window is determined from the windows of the vehicle according to the irradiation angle of the ambient light, wherein the target window includes the window through which the ambient light enters, and the light transmittance of the target window is increased to increase the ambient light entering the interior of the vehicle through the target window, thereby achieving the purpose of increasing the light energy generated by the interior of the vehicle being irradiated by the ambient light, and finally increasing the temperature inside the vehicle.

[0051] In addition, in the case where the detected light energy is less than the second preset energy threshold, in some embodiments, the target window can include other windows in addition to the window through which the ambient light enters, and the transmittance of all the windows of the vehicle is increased to quickly increase the ambient light entering the interior of the vehicle through the target window, thereby quickly increasing the temperature inside the vehicle.

[0052] The second preset energy threshold can be set according to actual conditions, and the embodiment is not limited. It should be noted that the second preset energy threshold is less than or equal to the first preset energy threshold.

[0053] In the above embodiment, when the detected illumination energy is less than the second preset energy threshold, the light transmittance of the vehicle window through which the ambient light enters can be automatically increased to achieve the purpose of raising the temperature inside the vehicle, without the need for manual operation by the user, and the convenience is stronger.

[0054] In the above embodiment, a plurality of light sensors are installed to detect the illumination intensity, and the illumination energy generated by the ambient light irradiating the interior of the vehicle is calculated based on the detected illumination intensity. Although this method can reduce the dependence on mathematical models, it increases the hardware cost and system complexity, and requires real-time processing and analysis of a large amount of sensor data, which is difficult to process. To reduce the hardware cost and system complexity, the embodiment of the present application provides another way to determine the illumination energy generated by the ambient light irradiating the interior of the vehicle. The ambient light includes sunlight, and specifically includes the following steps: Determine the sun position parameter; the sun position parameter includes at least one of the elevation angle and the azimuth angle; Calculate the illumination energy generated by the ambient light irradiating the interior of the vehicle according to the sun position parameter and the vehicle window parameter; the vehicle window parameter includes at least one of the vehicle window area and the vehicle window glass light transmittance.

[0055] The above-mentioned sun position parameter includes at least one of the elevation angle and the azimuth angle. The sun elevation angle refers to the angle between the sunray and the ground plane of the observation point, and the sun azimuth angle refers to the angle between the projection of the sunray on the ground plane of the observation point and the north direction of the point.

[0056] In a specific embodiment, the sun position parameter includes the elevation angle and the azimuth angle. The elevation angle and the azimuth angle can be obtained by accessing an online astronomical data service platform. The astronomical data service platform refers to a platform that provides real-time sun elevation angle and azimuth angle data at different times around the world.

[0057] Specifically, the latitude and longitude and time information of the vehicle can be sent to the astronomical data service platform through the network function of the vehicle, and the corresponding sun angle data can be returned by the astronomical data service platform. This method can reduce the computational burden of related devices in the vehicle.

[0058] Then, the illumination energy generated by the environmental light irradiating the interior of the vehicle is calculated according to the solar position parameter and the vehicle window parameter. The vehicle window parameter includes at least one of a vehicle window area and a vehicle window glass light transmittance. In a specific embodiment, the vehicle window parameter includes the vehicle window area and the vehicle window glass light transmittance. The vehicle window area can be pre-stored in the vehicle information database, and the vehicle window glass light transmittance is provided by a glass manufacturer and stored in the vehicle information database.

[0059] In a specific embodiment, the illumination energy generated by the environmental light irradiating the interior of the vehicle can be calculated according to the solar position parameter and the vehicle window parameter based on the following steps: The solar position parameter and the vehicle window parameter are input into a pre-trained illumination energy detection network model or a pre-defined function relationship between the illumination energy and the solar position parameter and the vehicle window parameter to obtain the illumination energy generated by the environmental light irradiating the interior of the vehicle.

[0060] The solar altitude angle and the solar azimuth angle determine the angle between the sunlight and the vehicle window, and further affect the intensity of the illumination energy in the interior of the vehicle. Generally, the greater the solar altitude angle, the closer the light irradiates vertically, and the stronger the illumination energy per unit area. The solar azimuth angle determines the direction of the light, and the illumination degree in different positions of the vehicle is different under different solar azimuth angles. By establishing a mathematical model of the illumination energy and the solar altitude angle, the solar azimuth angle, and the vehicle window area and glass material, the illumination energy generated by the environmental light irradiating the interior of the vehicle can be calculated.

[0061] In some embodiments, the illumination energy detection network model can be pre-trained. Specifically, the solar position parameter and the vehicle window parameter under different solar angles, weather conditions, and vehicle window positions can be obtained as training samples, and the illumination energy corresponding to each training sample is measured as a training label. When training the illumination energy detection network model, the training samples are input into the illumination energy detection network model to obtain the prediction result output by the illumination energy detection network model. By comparing the prediction result and the corresponding training label, the loss of the illumination energy detection network model is calculated. The parameters of the illumination energy detection network model are adjusted to reduce the loss of the illumination energy detection network model as the target. Then, the above training process is repeated until the illumination energy detection network model meets the training requirements.

[0062] The illumination energy detection network model can use any network model as a basic model for training, and the present embodiment is not limited thereto.

[0063] The solar position parameter and the vehicle window parameter are input into the pre-trained illumination energy detection network model to obtain the detection result output by the illumination energy detection network model, i.e., the illumination energy generated by the environmental light irradiating the interior of the vehicle.

[0064] This method can adapt to complex and variable actual situations and improve the accuracy of light energy recognition, but it requires a large amount of data for training, and the training and updating of the model requires certain computing resources and time.

[0065] In some other embodiments, a function relationship between the light energy and the solar position parameters and the vehicle window parameters can be predefined. For example, the function relationship can be expressed as: E=f(h,A,S,k) In the above formula, E represents the light energy, h represents the solar altitude angle, A represents the solar azimuth angle, S represents the vehicle window area, and k represents the glass light transmission coefficient. f is a function relationship between the light energy and the solar position parameters and the vehicle window parameters, which can be obtained through experiments or theoretical derivation, and is not limited in the present embodiment.

[0066] The solar position parameters and the vehicle window parameters are input into the above function relationship to obtain the light energy.

[0067] In addition, in order to improve the accuracy of the calculation, a light sensor can be installed at a proper position of the vehicle to detect the actual light intensity in real time, and the detection data can be used to calibrate and correct the light energy intensity calculated by the light energy detection network model or the above function relationship, and the detection data can also be used to modify the light energy detection network model or the above function relationship to improve the reliability of the light energy detection network model or the above function relationship.

[0068] In the above embodiments, the light energy generated by the environmental light irradiation in the interior of the vehicle can be calculated according to the solar position parameters and the vehicle window parameters, without the need to install a large number of light sensors, thereby reducing the hardware cost and system complexity.

[0069] In the steps of the above embodiments, the latitude and longitude and time information of the vehicle are sent to an astronomical data service platform through the network function of the vehicle to obtain the solar position parameters fed back by the astronomical data service platform, but this way requires the vehicle to have stable network connection, and there may be data delay and privacy security problems.

[0070] Based on this, another embodiment of the present application provides another way to determine the solar position parameters, and the specific steps include: Obtaining the latitude and longitude of the current location of the vehicle and the current time; and determining the solar position parameters according to the latitude and longitude and the current time.

[0071] Specifically, the global positioning system or other positioning module of the vehicle acquires the latitude and longitude information of the location where the vehicle is located in real time. At the same time, the clock module of the vehicle provides the accurate current time. According to astronomical principles, the solar altitude angle and the solar azimuth angle are related to the latitude and longitude of the vehicle location, time, and parameters such as the solar declination angle and the solar hour angle.

[0072] The solar declination angle and the solar hour angle can be calculated first, the solar altitude angle can be calculated according to the solar hour angle, the solar declination angle, and the latitude of the vehicle location, and the solar azimuth angle can be calculated according to the solar declination angle, the solar altitude angle, and the latitude of the vehicle location. The specific calculation formulas are as follows: The calculation formula of the solar declination angle is: δ represents the solar declination angle, N is the accumulated day, that is, the number of days calculated from January 1.

[0073] The calculation formula of the solar hour angle is: τ = 15 (S 12) + λ ω τ represents the solar hour angle, S represents the local mean solar time, ω represents the time difference, and λ represents the longitude of the vehicle location.

[0074] The calculation formula of the solar altitude angle is: sinh = sin φ sin δ + cos φ cos δ cos τ h represents the solar altitude angle, and φ represents the latitude of the vehicle location.

[0075] The calculation formula of the solar azimuth angle is: A represents the solar azimuth angle.

[0076] In the above embodiment, the solar position parameters can be calculated, which does not depend on the network connection of the vehicle and avoids possible data delay and privacy security problems.

[0077] In addition, the existing solar angle calculation formula is relatively complex and has a large amount of calculation. Some simplified algorithms can be researched and used to approximately calculate the solar altitude angle and the solar azimuth angle. For example, in some application scenarios, some secondary factors can be ignored, and a simplified trigonometric function relationship can be used to calculate the solar angle. Although the calculation accuracy of this method may be reduced, the calculation speed can be significantly improved, and the performance requirements of the vehicle-mounted calculation unit can be reduced. However, when using a simplified algorithm, the calculation error of different regions and different seasons needs to be fully evaluated and calibrated to ensure that the actual application requirements of the present embodiment are met.

[0078] In one specific embodiment, the illumination energy generated by the illumination of the interior of the vehicle by the ambient light refers to the illumination energy generated by the illumination of the front-row position of the interior of the vehicle by the ambient light, and the target window is determined from the driver-side window and the front passenger-side window of the front row of the vehicle when determining the target window.

[0079] For example, the illumination energy generated by the illumination of the front row of the vehicle by the ambient light is calculated according to the sun position parameter and the window parameter of the front-row window of the vehicle; if the illumination energy is greater than a first preset energy threshold, the target window is determined from the front-row window of the vehicle according to the illumination angle of the ambient light, and the light transmittance of the target window is reduced. If the illumination energy is less than a second preset energy threshold, the target window is determined from the front-row window of the vehicle according to the illumination angle of the ambient light, and the light transmittance of the target window is increased.

[0080] Corresponding to the foregoing application function implementation method embodiments, the present application also provides a window adjusting device, an electronic device, a vehicle, a computer readable storage medium, a computer program product, and corresponding embodiments.

[0081] Figure 2 FIG. 1 is a structural schematic diagram of a window adjusting device according to an embodiment of the present application.

[0082] Referring to Figure 2 The device comprises: A first determination module 100 configured to determine the illumination energy generated by the illumination of the interior of the vehicle by the ambient light.
