Description

Technical Field

[0001] The present disclosure relates to the fields of intelligent transportation and automotive technologies, and particularly to a control device, a control method, a vehicle, an electronic device, a storage medium, and a program product. Background Art

[0002] The rearview mirror of a motor vehicle is an important component for a driver to obtain road conditions information behind the vehicle. When driving at night, if the vehicle behind turns on its high beams, the rearview mirror will produce strong reflected light, causing glare to the driver. Glare can lead to a delay in the driver's operation response, seriously affecting driving safety. In addition, strong light can also cause eye fatigue and affect the driver's health. Summary of the Invention

[0003] The present disclosure provides a control device, a control method, a vehicle, an electronic device, a storage medium, and a program product.

[0005] For example, the processor is further configured to: when the light transmittance of the window glass is the third light transmittance, obtain the light intensity of the interior rearview mirror acquired by a second sensor of the vehicle; when determining that the light intensity of the interior rearview mirror is less than a second illuminance threshold, control the light transmittance of the window glass to be adjusted from the third light transmittance to a fourth light transmittance, where the fourth light transmittance is greater than the third light transmittance; and when determining that the light intensity of the interior rearview mirror is greater than or equal to the second illuminance threshold, control the light transmittance of the window glass to remain the third light transmittance.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure. It should be noted that throughout the drawings, the same elements are denoted by the same or similar reference numerals. In the following description, some specific embodiments are for illustrative purposes only and should not be construed as any limitation to the present disclosure, but merely examples of the embodiments of the present disclosure. Conventional structures or configurations will be omitted when they may cause confusion in the understanding of the present disclosure. It should be noted that the shapes and sizes of the components in the drawings do not reflect the actual sizes and proportions, but only illustrate the content of the embodiments of the present disclosure.

[0048] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the ordinary meanings understood by those skilled in the art. The "first", "second" and similar terms used in the embodiments of the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components.

[0049] Figure 1A and Figure 1B is a schematic diagram of an application scenario of a control device according to an embodiment of the present disclosure.

[0050] As Figure 1A shown, in application scenario 100a, vehicle 101 is traveling in front of vehicle 102. Vehicles 101 and 102 can both be small vehicles, such as sedans and SUVs.

[0051] When driving at night, when the rear vehicle 102 turns on its high beams, a strong reflected light will be generated on the rearview mirror of the front vehicle 101.

[0052] As Figure 1B shown, in application scenario 100b, vehicle 101 is traveling in front of vehicle 103. Vehicle 101 can be a small vehicle, such as a sedan and an SUV. Vehicle 102 can be a large vehicle, such as a truck, a bus and an engineering vehicle.

[0053] Since the height of the headlights of vehicle 103 is similar to the height of vehicle 102, when driving at night, when the rear vehicle 103 turns on its low beams and high beams, strong reflected light will also be generated on the rearview mirror of the front vehicle 101.

[0054] The strong reflected light from the rearview mirror will cause the driver to be dazzled, thus affecting the driving safety of the driver of the front vehicle 101. The strong reflected light from the rearview mirror will also cause eye fatigue and affect the health of the driver.

[0055] Generally, the driver of the front vehicle 101 cannot take measures to remind the rear vehicle 102 to turn off its high beams. The driver can manually adjust the angle of the interior rearview mirror to weaken the intensity of the reflected light, but the weakening effect is average and requires the driver to be distracted for calibration, which affects driving safety.

[0056] For example, an automatic anti-glare rearview mirror is installed to prevent the driver from being dazzled. The automatic anti-glare rearview mirror can automatically adjust the reflectivity through a photosensitive element to reduce the impact of the reflected light on the driver. However, the ambient light around vehicle 101 will affect the photosensitive element, resulting in the photosensitive element being unable to accurately distinguish the on / off situation of the low beams and high beams of the rear vehicles 102 and 103.

[0057] The present disclosure provides a control device. The control vehicle can be installed on vehicle 101. By controlling the light transmittance of the vehicle window of vehicle 101, the reflection effect of the rearview mirror can be weakened, the adverse effect of the reflected light of the rearview mirror on the driver can be reduced, and driving safety can be improved.

[0058] Figure 2 It is a schematic diagram of the control device according to an embodiment of the present disclosure.

[0059] As Figure 2 shown, the control device 200 includes a processor 210.

[0060] In an embodiment of the present disclosure, the processor 210 obtains the external light intensity acquired by the first sensor of the vehicle. When it is determined that the external light intensity is greater than or equal to the first illuminance threshold, the processor 210 controls the light transmittance of the vehicle window glass to be adjusted from the first light transmittance to the second light transmittance, and the first light transmittance is greater than the second light transmittance.

[0061] In an embodiment of the present disclosure, the vehicle is the current vehicle where the control device 200 is located. The first sensor may be a light sensor and is installed on the current vehicle. The first sensor is used to obtain the light intensity irradiating on the vehicle. For example, the vehicle window glass may be the rear window glass of the current vehicle, and the first sensor may be installed on the rear window glass. The first sensor obtains the external light intensity of the light emitted by the high beam of the vehicle behind irradiating on the rear window glass of the current vehicle.

[0062] For example, the first sensor may be disposed on the outer surface of the rear window glass, and the first sensor can determine the external light intensity according to the light intensity outside the rear window glass. For example, the first sensor may also be disposed on the inner surface of the rear window glass, and the first sensor can calculate the external light intensity of the rear window glass according to the light intensity passing through the rear window glass (the internal ambient light of the vehicle) and the light transmittance of the rear window glass.

[0063] For example, the light intensity refers to the luminous flux of visible light received per unit area, simply referred to as illuminance. The external light intensity is the luminous flux of visible light received on the outer surface of the rear window glass. Based on the external light intensity, the illumination degree of the outer surface of the rear window glass can be determined.

[0064] For example, the first illuminance threshold may be 5000 lumens, 5500 lumens or 6000 lumens, etc. For example, the first light transmittance may be 90%, and the second light transmittance may be 80%. The present disclosure does not limit the values of the first illuminance threshold, the first light transmittance and the second light transmittance.

[0065] The processor 210 may determine whether the vehicle behind has turned on its high beams based on the external light intensity acquired by the first sensor. For example, when it is determined that the external light intensity is greater than or equal to 5000 lumens, the processor 210 determines that the light intensity emitted by the vehicle light of the vehicle behind has reached the light intensity of the high beams. To ensure the safety of the driver of the current vehicle, the processor 210 controls the light transmittance of the rear window glass of the current vehicle to be adjusted from 90% to 80%.

[0066] In the embodiment of the present disclosure, the first light transmittance may be the default light transmittance of the rear window glass of the current vehicle. For example, when the current vehicle is started, the light transmittance of the rear window glass is the first light transmittance. For example, when driving during the day, the light transmittance of the rear window glass is the first light transmittance.

[0067] When the light transmittance of the rear window glass is adjusted from the first light transmittance to the second light transmittance, the light transmittance of the rear window glass of the current vehicle decreases. Therefore, the light intensity of the light emitted by the vehicle behind weakens after passing through the rear window glass, and the intensity of the light reflected by the interior rearview mirror of the current vehicle also weakens accordingly, thereby preventing the light reflected by the interior rearview mirror from causing the driver to be dazzled due to the excessive light emitted by the vehicle behind.

[0068] In the embodiment of the present disclosure, the vehicle behind may perform a high beam - low beam switch to alert the current vehicle. To prevent the current vehicle from misinterpreting the high beam - low beam switch performed by the vehicle behind as a continuous high beam, the processor 210 determines whether the vehicle behind is continuously turning on the high beams or performing a high beam - low beam switch according to the duration for which the external light intensity is greater than or equal to the first illuminance threshold.

[0069] When it is determined that the duration for which the external light intensity is greater than or equal to the first illuminance threshold is greater than or equal to the first duration, the processor 210 controls the light transmittance of the window glass to be adjusted from the second light transmittance to the third light transmittance, where the second light transmittance is greater than the third light transmittance.

[0070] For example, the first duration may be 10 s, and the third light transmittance may be 70%. The present disclosure does not limit the values of the first duration and the third light transmittance.

[0071] For example, when it is determined that the duration for which the external light intensity is greater than or equal to 5000 lumens is greater than or equal to 10 s, the processor 210 determines that the vehicle behind is continuously turning on the high beams. To ensure the safety of the driver of the current vehicle, the processor 210 controls the light transmittance of the rear window glass of the current vehicle to be adjusted from 80% to 70%, thereby further reducing the light transmittance of the rear window glass of the current vehicle, and the intensity of the light reflected by the interior rearview mirror also weakens accordingly, reducing the possibility of the light reflected by the interior rearview mirror causing the driver to be dazzled.

[0072] In an embodiment of the present disclosure, when it is determined that the external light intensity is greater than or equal to the first illuminance threshold and the distance between the vehicle and the vehicle behind is less than the first distance threshold, the processor 210 also controls the light transmittance of the window glass to be adjusted from the second light transmittance to the third light transmittance.

[0073] For example, the distance between the current vehicle and the vehicle behind can be obtained by a radar sensor. The first distance threshold can be 50 meters. The present disclosure does not limit the value of the first distance threshold.

[0074] For example, when it is determined that the external light intensity is greater than or equal to 5000 lumens and the distance between the vehicle and the vehicle behind is less than 50 meters, the processor 210 determines that the distance between the vehicle behind and the current vehicle is too close. The high beam briefly turned on by the vehicle behind will also affect the driving safety of the driver. Therefore, the processor 210 controls the light transmittance of the rear window glass of the current vehicle to be adjusted from 80% to 70%, thereby further reducing the light transmittance of the rear window glass of the current vehicle, and the intensity of the light reflected by the interior rearview mirror is also correspondingly weakened, reducing the possibility of the light reflected by the interior rearview mirror causing dizziness to the driver.

[0075] For example, when the vehicle behind is a large vehicle, when the distance between the large vehicle and the current vehicle is too close, the low beam turned on by the large vehicle will also affect the driving safety of the driver. Therefore, the processor 210 controls the light transmittance of the rear window glass of the current vehicle to be adjusted from 80% to 70%, thereby further reducing the light transmittance of the rear window glass of the current vehicle, and the intensity of the light reflected by the interior rearview mirror is also correspondingly weakened, reducing the possibility of the light reflected by the interior rearview mirror causing dizziness to the driver.

[0076] In an embodiment of the present disclosure, for condition 1) the duration for which the external light intensity is greater than or equal to the first illuminance threshold is greater than or equal to the first duration, and condition 2) the external light intensity is greater than or equal to the first illuminance threshold and the distance between the vehicle and the vehicle behind is less than the first distance threshold, when it is determined that at least one of condition 1) and condition 2) is satisfied, the processor 210 may control the light transmittance of the window glass to be adjusted from the second light transmittance to the third light transmittance.

[0077] In an embodiment of the present disclosure, the vehicle behind can be a small vehicle or a large vehicle. When the vehicle behind is a small vehicle and the high beam of the vehicle behind is turned on, the first sensor of the current vehicle can detect an external light intensity exceeding the first illuminance threshold. When the vehicle behind is a large vehicle and the high beam and low beam of the vehicle behind are turned on, the first sensor of the current vehicle can detect an external light intensity exceeding the first illuminance threshold. For example, in a congested traffic condition, when the vehicle behind is in a state of closely following the current vehicle all the time, the distance between the vehicle behind and the current vehicle is relatively close. When the large vehicle turns on the low beam, the first sensor of the current vehicle can also detect an external light intensity exceeding the first illuminance threshold.

[0078] In the embodiments of the present disclosure, the window glass can be the rear window glass of the current vehicle, or can also be the side window glass and the roof window glass of the current vehicle.

[0079] For example, the current vehicle is a small sedan, and the rear vehicle is any vehicle with a body height higher than that of the current vehicle, such as an off-road vehicle, a truck, a bus, an engineering vehicle, etc. Since the headlights of the rear vehicle are relatively high, the light emitted by the headlights of the rear vehicle may irradiate on the side window glass and the roof window glass of the current vehicle. The light emitted by the rear vehicle will enter the current vehicle through the side window glass and the roof window glass, and part of the light will be reflected by the interior rearview mirror to the eyes of the driver, causing dizziness. Therefore, external light sensors can also be installed on the side window glass and the roof window glass, and the processor 210 controls the light transmittance of the side window glass and the light transmittance of the roof window glass based on the light intensity obtained by the external light sensors installed on the side window glass and the roof window glass.

[0080] The way the processor 210 controls the light transmittance of the side window glass and the light transmittance of the roof window glass is similar to the way of controlling the light transmittance of the rear window glass, and will not be elaborated here.

[0081] In the embodiments of the present disclosure, the processor 210 can also determine whether the rear vehicle is a large vehicle or a small vehicle according to the angle and height of the light emitted by the rear vehicle detected by the sensor. For example, when it is determined that the height of the light detected by the sensor is mostly higher than the preset height, the rear vehicle is considered a large vehicle. For example, when it is determined that the angle of the light detected by the sensor is mostly incident from above, the rear vehicle is considered a large vehicle.

[0082] In the embodiments of the present disclosure, the processor 210 can also determine whether the rear vehicle is a large vehicle or a small vehicle according to the image of the rear vehicle obtained by the camera. For example, the processor 210 can automatically identify whether the rear vehicle is a large vehicle or a small vehicle according to the obtained image of the rear vehicle, or can also calculate the height and width of the rear vehicle according to the obtained image of the rear vehicle, so as to determine whether the rear vehicle is a large vehicle or a small vehicle.

[0083] Through the embodiments of the present disclosure, the processor 210 controls the light transmittance of the window glass according to the external light intensity obtained by the first sensor, thereby avoiding the strong light reflected by the rearview mirror of the current vehicle caused by the rear vehicle turning on the high beam, avoiding affecting the driving safety of the driver of the current vehicle, and improving the comfort of the driver.

[0084] Figure 3 It is a schematic diagram of the principle of controlling the light transmittance according to the embodiments of the present disclosure.

[0085] Such as Figure 3As shown, the light emitted by the headlight 301 of the rear vehicle passes through the rear window glass 302 of the current vehicle and irradiates on the interior rearview mirror 303 of the current vehicle. When the light intensity of the headlight 301 of the rear vehicle is too high, the light reflected by the interior rearview mirror 303 will cause the driver to feel dizzy.

[0086] In the disclosed embodiment, the first sensor obtains the external light intensity of the light emitted by the headlight 301 of the rear vehicle irradiating on the exterior of the rear window glass 302. The processor of the control device obtains the external light intensity. When it is determined that the external light intensity is greater than or equal to the first illuminance threshold, the control device adjusts the light transmittance of the rear window glass 302 from the first light transmittance to the second light transmittance. When it is determined that the duration for which the external light intensity is greater than or equal to the first illuminance threshold is greater than or equal to the first duration, the processor controls the light transmittance of the rear window glass 302 to be adjusted from the second light transmittance to the third light transmittance.

[0087] In some embodiments, when the light transmittance of the rear window glass 302 is the third light transmittance, the processor of the control device obtains the light intensity of the interior rearview mirror acquired by the second sensor of the vehicle. When it is determined that the light intensity of the interior rearview mirror 303 is less than the second illuminance threshold, the processor controls the light transmittance of the rear window glass 302 to be adjusted from the third light transmittance to the fourth light transmittance, and the fourth light transmittance is greater than the third light transmittance. When it is determined that the light intensity of the interior rearview mirror 303 is greater than or equal to the second illuminance threshold, the processor controls the light transmittance of the rear window glass 302 to remain at the third light transmittance.

[0088] In the disclosed embodiment of the present disclosure, the second sensor may be a light sensor, which is installed on the interior rearview mirror 303 and is used to obtain the light intensity of the interior rearview mirror 303. The light intensity of the interior rearview mirror 303 is the light intensity of the light passing through the rear window glass 302 and irradiating on the interior rearview mirror 303.

[0089] For example, the second illuminance threshold may be 500 lumens. For example, the fourth light transmittance may be 75%. The present disclosure does not limit the values of the second illuminance threshold and the fourth light transmittance.

[0090] The processor may determine the brightness of the interior rearview mirror 303 based on the light intensity of the interior rearview mirror 303 acquired by the second sensor. When the light transmittance of the rear window glass 302 is the third light transmittance, the brightness of the interior rearview mirror 303 may be relatively low, resulting in the driver being unable to clearly observe the situation around the current vehicle through the interior rearview mirror 303. Therefore, the light transmittance of the rear window glass 302 can be adjusted accordingly to increase the brightness of the interior rearview mirror 303.

[0091] For example, when it is determined that the illumination intensity of the interior rearview mirror 303 is less than 500 lumens, the processor determines that the brightness of the interior rearview mirror 303 is low. To ensure that the driver of the current vehicle can clearly observe the situation around the current vehicle through the interior rearview mirror 303, the processor controls the light transmittance of the rear window glass of the current vehicle to be adjusted from 70% to 75%. When it is determined that the illumination intensity of the interior rearview mirror 303 is greater than or equal to 500 lumens, the processor determines that the brightness of the interior rearview mirror 303 is sufficient for the driver of the current vehicle to clearly observe the situation around the current vehicle through the interior rearview mirror 303, and the processor can keep the light transmittance of the rear window glass 302 of the current vehicle at 70%.

[0092] In the embodiments of the present disclosure, the fourth light transmittance can be adjusted according to the actual situation. For example, when the light transmittance of the rear window glass 302 is 75%, but the illumination intensity of the interior rearview mirror 303 is still less than 500 lumens, the processor can increase the light transmittance of the rear window glass 302 again so that the illumination intensity of the interior rearview mirror 303 reaches 500 lumens.

[0093] For example, the processor can increase the light transmittance of the rear window glass 302 multiple times with an adjustment amplitude of 2% so that the illumination intensity of the interior rearview mirror 303 reaches 500 lumens. For example, the processor can also calculate the target light transmittance according to the external illumination intensity obtained by the first sensor so that when the light transmittance of the rear window glass 302 is the target light transmittance, the illumination intensity of the interior rearview mirror 303 reaches 500 lumens.

[0094] In some embodiments, when it is determined that the external illumination intensity is greater than or equal to the first illumination threshold, the light transmittance of the rear window glass 302 is controlled to be adjusted from the first light transmittance to the second light transmittance. When it is determined after the first time period that the duration for which the external illumination intensity is greater than or equal to the first illumination threshold is greater than or equal to the second time period and less than the first time period, the light transmittance of the window glass 302 is controlled to remain the second light transmittance. When it is determined after the first time period that the duration for which the external illumination intensity is greater than or equal to the first illumination threshold is less than the second time period, the light transmittance of the window glass 302 is controlled to be adjusted from the second light transmittance to the first light transmittance.

[0095] For example, the first time period can be 10 s and the second time period can be 6 s. The present disclosure does not limit the numerical values of the first time period and the second time period.

[0096] For example, after 10 s, the processor controls the light transmittance of the window glass 302 according to the external light intensity within these 10 s. For example, when it is determined that the duration during which the external light intensity is greater than or equal to 5000 lumens is less than 10 s and greater than 6 s, the processor determines that the vehicle behind is performing a high beam - low beam switch, and the processor can control the light transmittance of the window glass 302 to remain at 80%. When it is determined that the duration during which the external light intensity is greater than or equal to 5000 lumens is less than 6 s, the processor determines that the vehicle behind has briefly turned on the high beam and then turned it off, and the processor can control the light transmittance of the window glass 302 to be adjusted from 80% to 90%.

[0097] Through the embodiments of the present disclosure, the processor adaptively adjusts the light transmittance of the window glass 302 according to the duration for which the external light intensity exceeds the first illuminance threshold, improving the driving safety of the driver.

[0098] In some embodiments, when the light transmittance of the window glass 302 is the third light transmittance, the processor can continue to adjust the light transmittance of the window glass 302 according to the external light intensity of the window glass 302.

[0099] In the embodiments of the present disclosure, when the light transmittance of the window glass 302 is the third light transmittance, the first sensor continues to obtain the external light intensity. When it is determined that the duration during which the external light intensity is greater than or equal to the first illuminance threshold is greater than or equal to the first duration, the processor controls the light transmittance of the window glass 302 to remain at the third light transmittance. When it is determined that the duration during which the external light intensity is greater than or equal to the first illuminance threshold is less than the first duration and greater than or equal to the second duration after the first duration, the processor controls the light transmittance of the window glass 302 to be adjusted from the third light transmittance to the second light transmittance. When it is determined that the duration during which the external light intensity is greater than or equal to the first illuminance threshold is less than the second duration after the first duration, the processor controls the light transmittance of the window glass 302 to be adjusted from the third light transmittance to the first light transmittance.

[0100] For example, when the light transmittance of the window glass 302 is 70%, if it is determined that the external light intensity is greater than or equal to 5000 lumens and the duration for which the external light intensity is greater than or equal to 5000 lumens is greater than or equal to 10 s, the processor controls the light transmittance of the window glass 302 to remain at 70%. If it is determined that the external light intensity is greater than or equal to 5000 lumens, the duration for which the external light intensity is greater than or equal to 5000 lumens is less than 10 s and greater than or equal to 6 s, the processor controls the light transmittance of the window glass 302 to be adjusted from 70% to 80%. If it is determined that the external light intensity is greater than or equal to 5000 lumens and the duration for which the external light intensity is greater than or equal to 5000 lumens is less than 6 s, the processor controls the light transmittance of the window glass 302 to be adjusted from 70% to the first light transmittance of 90%.

[0101] In some embodiments, when the light transmittance of the window glass 302 is the second light transmittance, the processor may adjust the light transmittance of the window glass 302 according to the difference between the light intensity of the inside rearview mirror 303 at the current moment and the light intensity at the previous moment.

[0102] In the embodiments of the present disclosure, when the light transmittance of the window glass 302 is the second light transmittance, the processor obtains the first light intensity and the second light intensity of the inside rearview mirror acquired by the second sensor at a preset time interval, and the first light intensity is obtained earlier than the second light intensity. If it is determined that the second light intensity is greater than the first light intensity, it is considered that the external light intensity of the window glass 302 increases, and the processor controls the light transmittance of the window glass to be adjusted from the second light transmittance to the third light transmittance. If it is determined that the second light intensity is less than or equal to the first light intensity, it is considered that the external light intensity of the window glass 302 decreases or remains unchanged, and the processor controls the light transmittance of the window glass to remain at the second light transmittance.

[0103] For example, the preset time interval may be 10 s. The present disclosure does not limit the value of the preset time interval.

[0104] For example, when the light transmittance of the window glass 302 is 80%, the processor obtains the first light intensity acquired by the second sensor at time T1 and the second light intensity acquired at time T2. The interval between time T1 and time T2 is 10 s. For example, time T1 is the starting time, and after 10 s, time T2 is reached. If it is determined that the second light intensity is greater than the first light intensity, the processor controls the light transmittance of the window glass to be adjusted from 80% to 70%. If it is determined that the second light intensity is less than or equal to the first light intensity, the light transmittance of the window glass is controlled to remain at 80%.

[0105] When the light transmittance of the window glass 302 is 70%, the processor adjusts the light transmittance of the window glass 302 based on the light intensity of the inside rearview mirror 303. Similar to the method described above, when it is determined that the light intensity of the inside rearview mirror 303 is less than 500 lumens, the processor controls the light transmittance of the rear window glass of the current vehicle to be adjusted from 70% to 75%. When it is determined that the light intensity of the inside rearview mirror 303 is greater than or equal to 500 lumens, the processor can keep the light transmittance of the rear window glass of the current vehicle at 70%.

[0106] In some embodiments, the processor can also control the light transmittance of the window glass 302 according to the external light intensity of the window glass 302 and the external ambient light intensity of the current vehicle. For example, the external ambient light intensity can be obtained by the third sensor of the current vehicle. The third sensor can be a light sensor installed at the headlight of the current vehicle for obtaining the light intensity of the headlight of the current vehicle.

[0107] In the embodiments of the present disclosure, when it is determined that the external light intensity is less than the first illuminance threshold, the processor obtains the external ambient light intensity and pre-adjusts the light transmittance of the window glass 302 based on the external ambient light intensity. When it is determined that the illuminance ratio between the external light intensity and the external ambient light intensity is greater than or equal to the ratio threshold, the light transmittance of the window glass 302 is controlled to be adjusted from the first light transmittance to the second light transmittance.

[0108] For example, the ratio threshold can be 5. The present disclosure does not limit the value of the preset time interval.

[0109] For example, when it is determined that the external light intensity is less than 5000 lumens, the processor obtains the external ambient light intensity and the external light intensity. When it is determined that the illuminance ratio between the external light intensity and the external ambient light intensity is greater than or equal to 5, and the external light intensity of the window glass 302 is greater than the external ambient light intensity of the current vehicle, the processor controls the light transmittance of the window glass 302 to be adjusted from 90% to 80%.

[0110] In the embodiments of the present disclosure, when it is determined that the external light intensity is less than the first illuminance threshold, the processor obtains the distance between the vehicle and the vehicle behind obtained by the fourth sensor of the vehicle. When it is determined that the vehicle distance is greater than the second vehicle distance threshold and the illuminance ratio is greater than or equal to the ratio threshold, the light transmittance of the window glass is controlled to be adjusted from the first light transmittance to the second light transmittance.

[0111] For example, the fourth sensor can be a radar sensor installed at the rear of the current vehicle for obtaining the distance between the current vehicle and the vehicle behind. For example, the second vehicle distance threshold can be 100 meters. The second vehicle distance threshold and the first vehicle distance threshold can be equal or not equal. The present disclosure does not limit the value of the second vehicle distance threshold.

[0112] For example, when it is determined that the external light intensity is less than 5000 lumens, the processor obtains the distance between the current vehicle and the vehicle behind. When it is determined that the vehicle distance is greater than 100 meters and the illuminance ratio is greater than or equal to 5, the light transmittance of the window glass 302 is adjusted from 90% to 80%.

[0113] For example, when the vehicle behind gradually approaches the current vehicle, the external light intensity will gradually increase. Therefore, in order to improve the safety and comfort of the driver and passengers of the current vehicle, when it is determined that the vehicle distance is greater than the second vehicle distance threshold and the illuminance ratio is greater than or equal to the ratio threshold, the processor can adjust the light transmittance of the window glass 302 in advance without waiting for the external light intensity to reach the first illuminance threshold.

[0114] For example, the vehicle behind can be a large vehicle. Since the light intensity of the large vehicle's lights is relatively large and the illumination area of the large vehicle's lights is relatively large, when the vehicle distance between the large vehicle and the current vehicle is relatively close, the processor can also adjust the light transmittance of the window glass 302 in advance without waiting for the external light intensity to reach the first illuminance threshold.

[0115] In the embodiments of the present disclosure, when the vehicle behind turns on the high beam and is far away from the current vehicle, as the distance between the two vehicles gradually decreases, the external light intensity will gradually increase. If the illuminance ratio is greater than or equal to the ratio threshold, the external light intensity may exceed the first illuminance threshold. Therefore, the processor can adjust the light transmittance of the window glass 302 in advance to improve the driving comfort of the driver.

[0116] If the illuminance ratio is less than the ratio threshold, as the distance between the two vehicles gradually decreases, the external light intensity may not necessarily exceed the first illuminance threshold. Therefore, there is no need to adjust the light transmittance of the window glass 302 in advance. When the external light intensity of the window glass 302 exceeds the first illuminance threshold, the processor then controls the light transmittance of the window glass 302 to be adjusted from the first light transmittance to the second light transmittance.

[0117] In some embodiments, when the light transmittance of the window glass is the third light transmittance, the processor of the control device can control the rearview camera of the vehicle to turn on.

[0118] For example, when the light transmittance of the window glass is the third light transmittance, the light transmittance of the rear window glass is relatively low. To prevent the too low light transmittance of the rear window glass from affecting the driver's understanding of the external road conditions, the processor can send a start signal to the rearview camera to turn on the rearview camera.

[0119] For example, the rearview camera can be installed at the rear of the current vehicle to detect the road condition information behind the current vehicle.

[0120] For example, when the light transmittance of the window glass is the third light transmittance, the processor of the control device can also control the front camera, left camera, and right camera of the vehicle to turn on. The front camera is installed at the front of the current vehicle and is used to detect the road conditions behind the current vehicle. The left camera and the right camera are respectively installed at the left rearview mirror and the right rearview mirror of the current vehicle and are used to detect the road conditions on both sides of the current vehicle.

[0121] For example, when the light transmittance of the window glass is the third light transmittance, the processor of the control device can also control the 360° panoramic camera of the vehicle, and the 360° panoramic camera includes a rear camera.

[0122] The camera can be used to obtain the road conditions around the current vehicle and display them on the display of the current vehicle to assist the driver in driving and improve driving safety.

[0123] For example, when it is determined that the light transmittance of the window glass is the first light transmittance or the second light transmittance, the processor does not send a start signal to the rearview camera to reduce the resource overhead of the rearview camera operation. When it is determined that the light transmittance of the window glass is the first light transmittance or the second light transmittance, the processor can send a start signal to the rearview camera according to other relevant factors. For example, when the distance between the current vehicle and the vehicle behind is relatively close, the processor can send a start signal to the rearview camera without the light transmittance of the window glass. For example, when it is determined that the weather environment is poor or the road conditions are poor, the processor can send a start signal to the rearview camera without the light transmittance of the window glass.

[0124] In some embodiments, when the preset conditions are met, the processor controls the first sensor to obtain the external light intensity and adjusts the light transmittance of the window glass 302 based on the external light intensity.

[0125] In the embodiments of the present disclosure, the preset conditions may include but are not limited to: the current time is later than within a preset time period range and the vehicle's headlights are turned on.

[0126] For example, the preset time period range can be from 17:00 to 6:00 the next day, and the present disclosure does not limit the value of the preset time period range. When it is determined that the current time is later than 17:00, the driving environment of the vehicle becomes dark, and the vehicle behind may turn on the high beam. The processor controls the first sensor to obtain the external light intensity and adjusts the light transmittance of the window glass 302 based on the external light intensity. For example, when it is determined that the current vehicle has its headlights on, the processor believes that the current driving environment is dark, and the vehicle behind may also turn on the high beam. The processor controls the first sensor to obtain the external light intensity and adjusts the light transmittance of the window glass 302 based on the external light intensity. This can prevent the processor from adjusting the light transmittance of the window glass 302 during the day when the vehicle's lights are off, reducing resource consumption. This can also prevent the sunlight with the light intensity greater than or equal to the first illuminance threshold from being obtained by the first sensor, which may cause the processor to mis-adjust the light transmittance of the window glass 302.

[0127] Figure 4 It is a schematic diagram of a vehicle display according to an embodiment of the present disclosure.

[0128] As Figure 4 shown, the display 400 includes a main display 401 and a secondary display 402.

[0129] In an embodiment of the present disclosure, the display 400 can be a central control display of the current vehicle, and the display 400 can display a navigation screen and a road condition screen.

[0130] In an embodiment of the present disclosure, when it is determined that the rearview camera is turned on, the processor of the control device displays the road condition image obtained by the rearview camera on the vehicle's display 400. For example, the road condition image can be displayed on the main display 401.

[0131] In an embodiment of the present disclosure, when it is determined that the rearview camera is turned on and the display is currently showing a navigation screen, the navigation screen and the road condition image are displayed in a split screen on the display.

[0132] For example, the navigation screen can be displayed on the main display 401, and the road condition image can be displayed on the secondary display 402, thereby realizing the split screen display of the navigation screen and the road condition screen.

[0133] In an embodiment of the present disclosure, by using the rearview camera to obtain road condition information and synchronously display the road condition screen and the navigation screen, it can ensure the normal display of the navigation screen, assist the driver in driving, and improve driving safety.
