[0003] Motor vehicle rearview mirrors are crucial for drivers to obtain information about road conditions behind them. When driving at night, if the vehicle behind you uses its high beams, the rearview mirror will produce strong reflected light, which can dazzle the driver. This dazzle can delay the driver's reaction time, seriously compromising driving safety. Furthermore, strong light can cause eye fatigue and affect the driver's health. Summary of the Invention

[0004] The present disclosure provides a control device, a control method, a vehicle, an electronic device, a storage medium, and a program product.

[0005] According to a first aspect, the present disclosure provides a control device, including: a processor, configured to: obtain the external light intensity obtained by a first sensor of a vehicle; when it is determined that the external light intensity is greater than or equal to a first illuminance threshold, control the transmittance of the vehicle's window glass to be adjusted from a first transmittance to a second transmittance, where the first transmittance is greater than the second transmittance; and when it is determined that the duration of the external light intensity being greater than or equal to the first illuminance threshold is greater than or equal to a first duration, or 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 following vehicle is less than a first distance threshold, control the transmittance of the vehicle window glass to be adjusted from the second transmittance to a third transmittance, where the second transmittance is greater than the third transmittance.

[0006] For example, the processor is also configured to: when the transmittance of the vehicle window glass is a third transmittance, obtain 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 is less than the second illumination threshold, control the transmittance of the vehicle window glass to be adjusted from the third transmittance to a fourth transmittance, the fourth transmittance being greater than the third transmittance; and when it is determined that the light intensity of the interior rearview mirror is greater than or equal to the second illumination threshold, control the transmittance of the vehicle window glass to remain at the third transmittance.

[0007] For example, the processor is also configured to: when it is determined after the first time period that the duration of the external light intensity being greater than or equal to the first illuminance threshold is greater than or equal to the second time period and less than the first time period, control the transmittance of the vehicle window glass to remain at the second transmittance; and when it is determined after the first time period that the duration of the external light intensity being greater than or equal to the first illuminance threshold is less than the second time period, control the transmittance of the vehicle window glass to be adjusted from the second transmittance to the first transmittance.

[0048] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of them. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. It should be noted that throughout the drawings, the same elements are represented by the same or similar figure marks. In the following description, some specific embodiments are only for descriptive purposes and should not be understood as any limitation to the present disclosure, but are only 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 figures do not reflect the actual size and proportion, but only illustrate the contents of the embodiments of the present disclosure.

[0049] Unless otherwise defined, technical or scientific terms used in the embodiments of the present disclosure shall have the same general meaning as those skilled in the art. The terms "first," "second," and similar terms used in the embodiments of the present disclosure do not denote any order, quantity, or importance, but are merely used to distinguish different components.

[0050] 1A and 1B are schematic diagrams of application scenarios of a control device according to an embodiment of the present disclosure.

[0051] As shown in Figure 1A, in an application scenario 100a, a vehicle 101 is traveling in front of a vehicle 102. Both the vehicle 101 and the vehicle 102 may be small vehicles, such as a sedan and an off-road vehicle.

[0052] When driving at night, when the rear vehicle 102 turns on its high beam, the rearview mirror of the front vehicle 101 will produce strong reflected light.

[0053] As shown in FIG1B , in application scenario 100b, vehicle 101 is traveling in front of vehicle 103. Vehicle 101 may be a small vehicle, such as a sedan or SUV, while vehicle 102 may be a large vehicle, such as a truck, bus, or construction vehicle.

[0054] Since the height of the headlights of vehicle 103 is similar to that of vehicle 102 , when driving at night, when the rear vehicle 103 turns on the low beam and high beam, the rearview mirror of the front vehicle 101 will also produce strong reflected light.

[0055] The strong light reflected by the rearview mirror may cause dazzle to the driver, thereby affecting the driving safety of the driver of the front vehicle 101. The strong light reflected by the rearview mirror may also cause eye fatigue and affect the health of the driver.

[0056] Usually, the driver of the front vehicle 101 cannot take measures to remind the rear vehicle 102 to turn off the high beam. The driver can manually adjust the angle of the rearview mirror to reduce the intensity of the reflected light, but the reduction effect is general and requires the driver to be distracted to calibrate, affecting driving safety.

[0057] For example, an automatic anti-glare rearview mirror is installed to prevent glare for the driver. The automatic anti-glare rearview mirror can automatically adjust the reflectivity through the photosensitive element to reduce the impact of reflected light on the driver. However, the ambient light around the vehicle 101 affects the photosensitive element, resulting in the photosensitive element being unable to accurately distinguish whether the low beam and high beam of the rear vehicles 102 and 103 are on.

[0058] The present disclosure provides a control device that can be installed on a vehicle 101 and controls the light transmittance of the vehicle's windows to reduce the reflection effect of the rearview mirror, thereby alleviating the adverse effects of the rearview mirror's reflected light on the driver and improving driving safety.

[0059] FIG2 is a schematic diagram of a control device according to an embodiment of the present disclosure.

[0060] As shown in FIG. 2 , the control device 200 includes a processor 210 .

[0061] In an embodiment of the present disclosure, processor 210 obtains external light intensity obtained by a first sensor of the vehicle. If it is determined that the external light intensity is greater than or equal to a first illumination threshold, processor 210 controls the light transmittance of the vehicle's window glass to be adjusted from a first light transmittance to a second light transmittance, where the first light transmittance is greater than the second light transmittance.

[0062] In the disclosed embodiment, the vehicle is the current vehicle in which the control device 200 is located. The first sensor may be a light sensor mounted on the current vehicle. The first sensor is configured to obtain the intensity of light incident on the vehicle. For example, the vehicle window may be the rear window of the current vehicle, and the first sensor may be mounted on the rear window. The first sensor obtains the intensity of external light incident on the rear window of the current vehicle, caused by the high beam of a vehicle behind.

[0063] For example, the first sensor may be disposed on the outer surface of the rear window glass, and the first sensor may determine the external light intensity based on 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 may calculate the external light intensity of the rear window glass based on the light intensity (interior ambient light of the vehicle) transmitted through the rear window glass and the light transmittance of the rear window glass.

[0064] For example, light intensity refers to the luminous flux of visible light received per unit area, also known as illuminance. External light intensity is the luminous flux of visible light received by the outer surface of the rear window. Based on the external light intensity, the degree of illumination of the outer surface of the rear window can be determined.

[0065] For example, the first illumination 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 illumination threshold, the first light transmittance, and the second light transmittance.

[0066] Processor 210 can determine whether the rear vehicle's high beams are engaged based on the external light intensity detected by the first sensor. For example, if the external light intensity is determined to be greater than or equal to 5,000 lumens, processor 210 determines that the light intensity emitted by the rear vehicle's headlights has reached the high beam intensity. To ensure the safety of the current vehicle's driver, processor 210 controls the light transmittance of the current vehicle's rear window glass to be adjusted from 90% to 80%.

[0067] In the disclosed embodiment, the first transmittance may be the default transmittance of the rear window glass of the current vehicle. For example, when the current vehicle is started, the transmittance of the rear window glass is the first transmittance. For example, when the vehicle is driving during the day, the transmittance of the rear window glass is the first transmittance.

[0068] 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 intensity of the light emitted by the rear vehicle is weakened after passing through the rear window, and the intensity of the light reflected by the interior rearview mirror of the current vehicle is also weakened accordingly, thereby preventing the light emitted by the rear vehicle from being too strong and causing dizziness to the driver due to the light reflected from the interior rearview mirror.

[0069] In the disclosed embodiment, a following vehicle may perform a high-beam-to-low-beam switch to alert the current vehicle. To prevent the current vehicle from mistaking the high-beam-to-low-beam switch performed by the following vehicle as a continuous high beam, the processor 210 determines whether the following vehicle is continuously using high beams or performing a high-beam-to-low-beam switch based on the duration of time during which the external light intensity is greater than or equal to the first illumination threshold.

[0070] When it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold is greater than or equal to the first duration, the processor 210 controls the transmittance of the vehicle window glass to be adjusted from the second transmittance to the third transmittance, and the second transmittance is greater than the third transmittance.

[0071] For example, the first duration may be 10 seconds, 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.

[0072] For example, if the external light intensity is greater than or equal to 5000 lumens and the duration is greater than or equal to 10 seconds, processor 210 determines that the rear vehicle is continuously using its high beams. To ensure the safety of the current vehicle's driver, processor 210 controls the transmittance of the current vehicle's rear window to be adjusted from 80% to 70%, thereby further reducing the transmittance of the current vehicle's rear window. This also reduces the intensity of the light reflected from the rearview mirror, thereby reducing the possibility of the light reflected from the rearview mirror causing dizziness to the driver.

[0073] In the embodiment of the present disclosure, when it is determined that the external light intensity is greater than or equal to the first illumination threshold and the distance between the vehicle and the following vehicle is less than the first distance threshold, the processor 210 also controls the transmittance of the vehicle window glass to be adjusted from the second transmittance to the third transmittance.

[0074] 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.

[0075] For example, if the external light intensity is determined to be greater than or equal to 5000 lumens and the distance between the vehicle and the following vehicle is less than 50 meters, processor 210 determines that the following vehicle is too close to the current vehicle. The short-lived high beams of the following vehicle can also affect the driver's driving safety. Therefore, processor 210 controls the transmittance of the current vehicle's rear window to be adjusted from 80% to 70%, thereby further reducing the transmittance of the current vehicle's rear window. The intensity of the light reflected from the rearview mirror is also reduced accordingly, reducing the possibility of the reflected light from the rearview mirror causing dizziness to the driver.

[0076] For example, if the vehicle behind is a large vehicle and the distance between the current vehicle and the large vehicle and the low beam headlights of the large vehicle is too close, the driver's driving safety may be affected. Therefore, the processor 210 controls the light transmittance of the rear window of the current vehicle to be adjusted from 80% to 70%, thereby further reducing the light transmittance of the rear window of the current vehicle and the intensity of the light reflected by the rearview mirror. This reduces the possibility of the light reflected by the rearview mirror causing dizziness to the driver.

[0077] In the embodiment of the present disclosure, for condition 1) the duration of the external light intensity being greater than or equal to the first illumination threshold being greater than or equal to the first duration and condition 2) the external light intensity being greater than or equal to the first illumination threshold and the distance between the vehicle and the following vehicle being less than the first distance threshold, upon determining that at least one of condition 1) and condition 2) is met, the processor 210 may control the transmittance of the vehicle window glass to be adjusted from the second transmittance to the third transmittance.

[0078] In the disclosed embodiment, the rear vehicle may be a small vehicle or a large vehicle. When the rear vehicle is a small vehicle, the rear vehicle turns on the high beam, and the first sensor of the current vehicle can detect an external light intensity exceeding the first illumination threshold. When the rear vehicle is a large vehicle, the rear vehicle turns on the high beam and the low beam, and the first sensor of the current vehicle can detect an external light intensity exceeding the first illumination threshold. For example, in a congested road condition, the rear vehicle is in a state of always following the current vehicle, and the distance between the rear vehicle 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 illumination threshold.

[0079] In the embodiment of the present disclosure, the vehicle window glass may be the rear window glass of the current vehicle, or may be the side window glass and the roof window glass of the current vehicle.

[0080] For example, the current vehicle is a small sedan, and the rear vehicle is an off-road vehicle, truck, bus, engineering vehicle, or any other vehicle with a body height higher than the current vehicle. Since the headlights of the rear vehicle are higher, the light emitted by the headlights of the rear vehicle may shine on the side windows and roof window of the current vehicle. The light from the rear vehicle will be absorbed into the current vehicle through the side windows and roof window, so that part of the light will be reflected to the driver's eyes through the rearview mirror, causing dizziness. Therefore, external light sensors can also be installed on the side windows and roof window. The processor 210 controls the light transmittance of the side windows and the light transmittance of the roof window based on the light intensity obtained by the external light sensors installed on the side windows and roof window.

[0081] The way in which 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 in which the processor 210 controls the light transmittance of the rear window glass, and will not be repeated here.

[0082] In the disclosed embodiment, the processor 210 may also determine whether the rear vehicle is a large vehicle or a small vehicle based on the angle and height of the light emitted by the rear vehicle detected by the sensor. For example, if the height of the light detected by the sensor is mostly above a preset height, the rear vehicle is considered to be a large vehicle. For example, if the angle of the light detected by the sensor is mostly from a top-down perspective, the rear vehicle is considered to be a large vehicle.

[0083] In the disclosed embodiment, the processor 210 may also determine whether the rear vehicle is a large vehicle or a small vehicle based on the image of the rear vehicle captured by the camera. For example, the processor 210 may automatically identify whether the rear vehicle is a large vehicle or a small vehicle based on the captured image of the rear vehicle, or may calculate the height and width of the rear vehicle based on the captured image of the rear vehicle to determine whether the rear vehicle is a large vehicle or a small vehicle.

[0084] Through the embodiment of the present disclosure, the processor 210 controls the light transmittance of the vehicle window glass according to the external light intensity obtained by the first sensor, thereby preventing the rearview mirror of the current vehicle from reflecting strong light when the rear vehicle turns on the high beam, avoiding affecting the driving safety of the driver of the current vehicle, and providing driver comfort.

[0085] FIG3 is a schematic diagram showing the principle of controlling light transmittance according to an embodiment of the present disclosure.

[0086] As shown in Figure 3, the light emitted by the headlights 301 of the rear vehicle passes through the rear window glass 302 of the current vehicle and shines on the interior rearview mirror 303 of the current vehicle. When the light intensity emitted by the headlights 301 of the rear vehicle is too strong, the light reflected by the interior rearview mirror 303 may cause dizziness to the driver.

[0087] In the disclosed embodiment, a first sensor obtains the external light intensity of light emitted by a rear vehicle's headlight 301 and irradiates the rear window glass 302. The processor of the control device obtains the external light intensity and, upon determining that the external light intensity is greater than or equal to a first illumination threshold, controls the light transmittance of the rear window glass 302 to be adjusted from a first light transmittance to a second light transmittance. Upon determining that the duration of the external light intensity being greater than or equal to the first illumination threshold is greater than or equal to a first duration, the processor controls the light transmittance of the rear window glass 302 to be adjusted from the second light transmittance to a third light transmittance.

[0088] In some embodiments, when the light transmittance of rear window glass 302 is a third light transmittance, the processor of the control device obtains the light intensity of the interior rearview mirror captured by the vehicle's second sensor. If it is determined that the light intensity of interior rearview mirror 303 is less than a second illumination threshold, the processor controls the light transmittance of rear window glass 302 to adjust from the third light transmittance to a fourth light transmittance, where the fourth light transmittance is greater than the third light transmittance. If it is determined that the light intensity of interior rearview mirror 303 is greater than or equal to the second illumination threshold, the processor controls the light transmittance of rear window glass 302 to remain at the third light transmittance.

[0089] In the embodiment of the present disclosure, the second sensor may be a light sensor, which is mounted 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 the interior rearview mirror 303.

[0090] For example, the second illumination 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 illumination threshold and the fourth light transmittance.

[0091] The processor can determine the brightness of the interior rearview mirror 303 based on the light intensity of the interior rearview mirror 303 obtained 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 low, resulting in the driver being unable to clearly observe the current situation around the 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.

[0092] For example, if the illumination intensity of the interior rearview mirror 303 is determined to be 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 surroundings of 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%. If the illumination intensity of the interior rearview mirror 303 is determined to be 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 surroundings of the current vehicle through the interior rearview mirror 303, and the processor may maintain the light transmittance of the rear window glass 302 of the current vehicle at 70%.

[0093] In the disclosed embodiment, the fourth light transmittance can be adjusted based on actual conditions. For example, when the light transmittance of the rear window 302 is 75%, but the light intensity of the rearview mirror 303 is still less than 500 lumens, the processor can further increase the light transmittance of the rear window 302 so that the light intensity of the rearview mirror 303 reaches 500 lumens.

[0094] For example, the processor may increase the light transmittance of the rear window glass 302 multiple times in 2% increments, so that the light intensity of the interior rearview mirror 303 reaches 500 lumens. For example, the processor may also calculate a target light transmittance based on the external light intensity obtained by the first sensor, so that when the light transmittance of the rear window glass 302 reaches the target light transmittance, the light intensity of the interior rearview mirror 303 reaches 500 lumens.

[0095] In some embodiments, if the external light intensity is determined to be greater than or equal to a 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. If, after a first duration, it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold is greater than or equal to a second duration and less than the first duration, the light transmittance of the vehicle window glass 302 is controlled to remain at the second light transmittance. If, after the first duration, it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold is less than the second duration, the light transmittance of the vehicle window glass 302 is controlled to be adjusted from the second light transmittance to the first light transmittance.

[0096] For example, the first duration may be 10 seconds, and the second duration may be 6 seconds. The present disclosure does not limit the values ​​of the first duration and the second duration.

[0097] For example, after 10 seconds, the processor controls the light transmittance of vehicle window glass 302 based on the external light intensity during those 10 seconds. For example, if the duration of the external light intensity being greater than or equal to 5000 lumens is less than 10 seconds and greater than 6 seconds, the processor determines that the vehicle behind is switching from high beam to low beam, and the processor may control the light transmittance of vehicle window glass 302 to remain at 80%. If the duration of the external light intensity being greater than or equal to 5000 lumens is less than 6 seconds, the processor determines that the vehicle behind briefly activated its high beam and then subsequently turned it off, and the processor may control the light transmittance of vehicle window glass 302 to adjust from 80% to 90%.

[0098] Through the embodiment of the present disclosure, the processor adaptively adjusts the light transmittance of the vehicle window glass 302 according to the duration that the external light intensity exceeds the first illumination threshold, thereby improving the driving safety of the driver.

[0099] In some embodiments, when the light transmittance of the vehicle window glass 302 is the third light transmittance, the processor may continue to adjust the light transmittance of the vehicle window glass 302 according to the external light intensity of the vehicle window glass 302 .

[0100] In an embodiment of the present disclosure, when the light transmittance of the vehicle window glass 302 is the third light transmittance, the first sensor continues to acquire the external light intensity. If it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold is greater than or equal to a first duration, the processor controls the light transmittance of the vehicle window glass 302 to remain at the third light transmittance. If, after the first duration, it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold is less than the first duration and greater than or equal to a second duration, the processor controls the light transmittance of the vehicle window glass 302 to adjust from the third light transmittance to the second light transmittance. If, after the first duration, it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold is less than the second duration, the processor controls the light transmittance of the vehicle window glass 302 to adjust from the third light transmittance to the first light transmittance.

[0101] For example, if the light transmittance of vehicle window glass 302 is 70%, and if it is determined that the external light intensity is greater than or equal to 5000 lumens and the duration of the external light intensity being greater than or equal to 5000 lumens is greater than or equal to 10 seconds, the processor controls the light transmittance of vehicle window glass 302 to remain at 70%. If it is determined that the external light intensity is greater than or equal to 5000 lumens and the duration of the external light intensity being greater than or equal to 5000 lumens is less than 10 seconds and greater than or equal to 6 seconds, the processor controls the light transmittance of vehicle 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 of the external light intensity being greater than or equal to 5000 lumens is less than 6 seconds, the processor controls the light transmittance of vehicle window glass 302 to be adjusted from 70% to the first light transmittance of 90%.

[0102] In some embodiments, when the light transmittance of the vehicle window glass 302 is the second light transmittance, the processor can adjust the light transmittance of the vehicle window glass 302 according to the difference between the light intensity of the rearview mirror 303 at the current moment and the light intensity at the previous moment.

[0103] In the disclosed embodiment, when the light transmittance of vehicle window glass 302 is the second light transmittance, the processor obtains the first light intensity and the second light intensity of the interior rearview mirror captured by the second sensor at preset time intervals, with the first light intensity being 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 vehicle window glass 302 has increased, and the processor controls the light transmittance of the vehicle 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 vehicle window glass 302 has decreased or remained unchanged, and the processor controls the light transmittance of the vehicle window glass to remain at the second light transmittance.

[0104] For example, the preset time interval may be 10 seconds. The present disclosure does not limit the value of the preset time interval.

[0105] For example, if the transmittance of vehicle window glass 302 is 80%, the processor obtains the first light intensity captured by the second sensor at time T1 and the second light intensity captured at time T2. The interval between time T1 and time T2 is 10 seconds. For example, time T1 is the starting time, and after 10 seconds, time T2 is reached. If the second light intensity is determined to be greater than the first light intensity, the processor controls the transmittance of the vehicle window glass to adjust from 80% to 70%. If the second light intensity is determined to be less than or equal to the first light intensity, the transmittance of the vehicle window glass is controlled to remain at 80%.

[0106] When the light transmittance of vehicle window glass 302 is 70%, the processor adjusts the light transmittance of vehicle window glass 302 based on the light intensity of interior rearview mirror 303. Similar to the method described above, if the light intensity of interior rearview mirror 303 is determined to be less than 500 lumens, the processor controls the light transmittance of the vehicle's rear window glass to be adjusted from 70% to 75%. If the light intensity of interior rearview mirror 303 is determined to be greater than or equal to 500 lumens, the processor may maintain the light transmittance of the vehicle's rear window glass at 70%.

[0107] In some embodiments, the processor may further control the light transmittance of the vehicle window glass 302 based on the external light intensity of the vehicle window glass 302 and the external ambient light intensity of the current vehicle. For example, the external ambient light intensity may be obtained by a third sensor of the current vehicle. The third sensor may be a light sensor installed in the headlight of the current vehicle to obtain the light intensity of the headlight of the current vehicle.

[0108] In the embodiment of the present disclosure, if the external light intensity is determined to be less than a first illumination threshold, the processor obtains the external ambient light intensity and pre-adjusts the light transmittance of vehicle window glass 302 based on the external ambient light intensity. If the illumination ratio between the external light intensity and the external ambient light intensity is determined to be greater than or equal to the ratio threshold, the light transmittance of vehicle window glass 302 is controlled to be adjusted from the first light transmittance to the second light transmittance.

[0109] For example, the ratio threshold may be 5. The present disclosure does not limit the value of the preset time interval.

[0110] For example, if the external light intensity is determined to be less than 5000 lumens, the processor obtains the external ambient light intensity and the external light intensity. If the illuminance ratio between the external light intensity and the external ambient light intensity is determined to be greater than or equal to 5, the external light intensity of the vehicle window glass 302 is greater than the current vehicle external ambient light intensity, and the processor controls the light transmittance of the vehicle window glass 302 to be adjusted from 90% to 80%.

[0111] In the disclosed embodiment, if the external light intensity is determined to be less than a first illumination threshold, the processor obtains the distance between the vehicle and the vehicle behind it, as acquired by the fourth sensor of the vehicle. If the distance is determined to be greater than a second distance threshold and the illumination ratio is greater than or equal to the ratio threshold, the processor controls the light transmittance of the vehicle window glass to be adjusted from the first light transmittance to the second light transmittance.

[0112] For example, the fourth sensor may be a radar sensor mounted at the rear of the current vehicle, configured to obtain the distance between the current vehicle and the vehicle behind it. For example, the second vehicle distance threshold may be 100 meters. The second vehicle distance threshold may be equal to or different from the first vehicle distance threshold, and this disclosure does not limit the value of the second vehicle distance threshold.

[0113] For example, if the external light intensity is determined to be less than 5000 lumens, the processor obtains the distance between the current vehicle and the vehicle behind. If the distance is determined to be greater than 100 meters and the illumination ratio is greater than or equal to 5, the light transmittance of the window glass 302 is controlled to be adjusted from 90% to 80%.

[0114] For example, as a rear vehicle approaches the current vehicle, the external light intensity gradually increases. Therefore, to improve the safety and comfort of the current vehicle's driver and passengers, if 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 vehicle window glass 302 in advance, without waiting for the external light intensity to reach the first illuminance threshold.

[0115] For example, the vehicle behind may be a large vehicle. Since the light intensity of a large vehicle's headlights is greater and the illumination area of ​​the large vehicle's headlights is larger, when the distance between the large vehicle and the current vehicle is closer, the processor may also adjust the light transmittance of the vehicle window glass 302 in advance without waiting for the external light intensity to reach the first illumination threshold.

[0116] In the disclosed embodiment, when a following vehicle has its high beams on and is relatively far from the current vehicle, the external light intensity gradually increases as the distance between the two vehicles decreases. 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 vehicle window glass 302 in advance to improve driving comfort for the driver.

[0117] If the illuminance ratio is less than the ratio threshold, as the distance between the two vehicles gradually decreases, the external light intensity will not necessarily exceed the first illuminance threshold, so 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 controls the light transmittance of the window glass 302 to be adjusted from the first light transmittance to the second light transmittance.

[0118] In some embodiments, when the light transmittance of the vehicle window glass is a third light transmittance, the processor of the control device can control the rearview camera of the vehicle to turn on.

[0119] For example, when the transmittance of the vehicle window glass is the third transmittance, the transmittance of the rear window glass is low. To prevent the transmittance of the rear window glass from being too low and 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.

[0120] For example, a rearview camera may be installed at the rear of the current vehicle to detect road condition information behind the current vehicle.

[0121] For example, when the light transmittance of the vehicle window glass is a third light transmittance, the processor of the control device can also control the vehicle's front camera, left camera, and right camera to turn on. The front camera is installed at the front of the vehicle and is used to detect road conditions behind the vehicle. The left camera and right camera are installed in the left and right rearview mirrors of the vehicle, respectively, and are used to detect road conditions on both sides of the vehicle.

[0122] For example, when the light transmittance of the vehicle window glass is the third light transmittance, the processor of the control device can also control the vehicle's 360° panoramic camera, which includes a rear camera.

[0123] The camera can be used to obtain road condition information around the current vehicle and display it on the current vehicle's display to assist the driver and improve driving safety.

[0124] For example, if the light transmittance of the vehicle window glass is determined to be the first or second light transmittance, the processor does not send a start signal to the rearview camera, thereby reducing the resource overhead of the rearview camera operation. If the light transmittance of the vehicle window glass is determined to be the first or second light transmittance, the processor may send a start signal to the rearview camera based on other relevant factors. For example, if the distance between the current vehicle and the vehicle behind is close, the processor may send a start signal to the rearview camera without considering the light transmittance of the vehicle window glass. For example, if the weather conditions or road conditions are determined to be poor, the processor may send a start signal to the rearview camera without considering the light transmittance of the vehicle window glass.

[0125] In some embodiments, when a preset condition is met, the processor controls the first sensor to obtain the external light intensity and adjusts the light transmittance of the vehicle window glass 302 based on the external light intensity.

[0126] In the embodiment of the present disclosure, the preset conditions may include but are not limited to: the current time is later than the preset time period and the vehicle lights are turned on.

[0127] For example, the preset time period may be from 5:00 PM to 6:00 AM the following day. This disclosure does not limit the numerical value of the preset time period. If it is determined that the current time is later than 5:00 PM, the vehicle's driving environment has become darker, and the vehicle behind may have its high beams on. The processor controls the first sensor to obtain the external light intensity and adjusts the transmittance of the vehicle window glass 302 based on the external light intensity. For example, if it is determined that the current vehicle has its lights on, the processor believes that the current driving environment has become darker, and the vehicle behind may also have its high beams on. The processor controls the first sensor to obtain the external light intensity and adjusts the transmittance of the vehicle window glass 302 based on the external light intensity. This can prevent the processor from adjusting the transmittance of the vehicle window glass 302 during the day when the vehicle's lights are not on, reducing resource overhead. This can also prevent the processor from erroneously adjusting the transmittance of the vehicle window glass 302 when the light intensity obtained by the first sensor is greater than or equal to the first illumination threshold.

[0128] FIG4 is a schematic diagram of a vehicle display according to an embodiment of the present disclosure.

[0129] As shown in FIG. 4 , the display 400 includes a main display 401 and a sub-display 402 .

[0130] In the embodiment of the present disclosure, the display 400 may be a central control display of the current vehicle, and the display 400 may display a navigation screen and a road condition screen.

[0131] In the 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 acquired by the rearview camera on the vehicle display 400. For example, the road condition image can be displayed on the main display 401.

[0132] In an embodiment of the present disclosure, when it is determined that the rearview camera is turned on and the display currently displays a navigation picture, the navigation picture and the road condition image are controlled to be displayed on the display in split screen.

[0133] For example, the navigation screen can be displayed on the main display 401 and the road condition image can be displayed on the sub-display 402, thereby realizing split-screen display of the navigation screen and the road condition image.

[0134] In the disclosed embodiment, a rearview camera is used to obtain road condition information, and the road condition picture and the navigation picture are displayed synchronously, which can ensure that the navigation picture is displayed normally, assist the driver in driving, and improve driving safety.

[0170] The control device 704 includes a processor. The processor obtains external light intensity and, if it is determined that the external light intensity is greater than or equal to a first illumination threshold, controls the light transmittance of the vehicle window glass 703 to be adjusted from the first light transmittance to the second light transmittance. Furthermore, if it is determined that the duration during which the external light intensity is greater than or equal to the first illumination threshold is greater than or equal to a first duration, or if it is determined that the external light intensity is greater than or equal to the first illumination threshold and the distance between the vehicle and the following vehicle is less than a first distance threshold, controls the light transmittance of the vehicle window glass 703 to be adjusted from the second light transmittance to a third light transmittance.

[0171] In the embodiment of the present disclosure, if it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold after the first time period is greater than or equal to the second time period and less than the first time period, the processor controls the light transmittance of the vehicle window glass 702 to remain at the second light transmittance. If it is determined that the duration of the external light intensity being greater than or equal to the first illumination threshold after the first time period is less than the second time period, the processor controls the light transmittance of the vehicle window glass 702 to adjust from the second light transmittance to the first light transmittance.

The second sensor 806 obtains the light intensity of the interior rearview mirror 805.

[0178] In the embodiment of the present disclosure, when the light transmittance of vehicle window glass 802 is the third light transmittance, control device 804 obtains the light intensity of the interior rearview mirror. If it is determined that the light intensity of the interior rearview mirror is less than the second illumination threshold, control device 804 controls the light transmittance of vehicle window glass 802 to adjust from the third light transmittance to a fourth light transmittance, where the fourth light transmittance is greater than the third light transmittance. If it is determined that the light intensity of the interior rearview mirror is greater than or equal to the second illumination threshold, control device 804 controls the light transmittance of vehicle window glass 802 to remain at the third light transmittance.

[0179] In the disclosed embodiment, the second sensor 806 captures a first light intensity and a second light intensity from the interior rearview mirror 805 at preset time intervals, with the first light intensity being captured earlier than the second light intensity. When the transmittance of the vehicle window glass 802 is the second transmittance, the control device 804 captures the first light intensity and the second light intensity. If the second light intensity is determined to be greater than the first light intensity, the control device 804 controls the transmittance of the vehicle window glass 802 to adjust from the second transmittance to a third transmittance. If the second light intensity is determined to be less than or equal to the first light intensity, the control device 804 controls the transmittance of the vehicle window glass 802 to remain at the second transmittance.

[0180] In the disclosed embodiment, the third sensor 807 is disposed on the vehicle body 801. For example, the third sensor 807 can be disposed in the vehicle body 801 near the headlights. The third sensor 807 obtains the external ambient light intensity of the vehicle. If the external light intensity is determined to be less than a first illumination threshold, the control device 804 obtains the external ambient light intensity. If the illumination ratio between the external light intensity and the external ambient light intensity is determined to be greater than or equal to the ratio threshold, the control device 804 controls the light transmittance of the vehicle window glass 802 to adjust from the first light transmittance to the second light transmittance.

[0181] In the disclosed embodiment, fourth sensor 808 is disposed on vehicle body 801, for example, at the rear of vehicle body 801. Fourth sensor 808 detects the distance between the vehicle and the following vehicle. If the external light intensity is determined to be less than a first illumination threshold, control device 804 detects the distance. If the distance is greater than a second distance threshold and the illumination ratio is greater than or equal to the ratio threshold, control device 804 controls the light transmittance of window glass 802 to adjust from the first light transmittance to the second light transmittance.

[0182] In the embodiment of the present disclosure, rearview camera 809 is mounted on vehicle body 801. For example, rearview camera 809 may be mounted on the top of vehicle body 801. When the light transmittance of vehicle window glass 802 is the third light transmittance, control device 804 controls rearview camera 809 to turn on. When it is determined that the light transmittance of vehicle window glass 802 has been adjusted from the third light transmittance to the first light transmittance or the second light transmittance, control device 804 controls rearview camera 809 to turn on or off.

[0183] In the disclosed embodiment, a display 810 is mounted on the vehicle body 801. A rearview camera 809 captures images of road conditions. If the rearview camera is determined to be on, the control device 804 displays the images of road conditions on the display 810. If the rearview camera 809 is determined to be on and the display is currently displaying a navigation screen, the control device 804 controls the display to display the navigation screen and the road condition image separately.

[0184] In the embodiment of the present disclosure, if at least one of the following preset conditions is determined to be satisfied, the control device 804 controls the first sensor to obtain 803 the external light intensity.
