[0038] See also Figure 1, which is a schematic diagram of a process of preventing vehicle light glare provided in an embodiment of the present application, and may specifically include:

[0039] S110: Detecting an external light source of the vehicle based on the light sensor to obtain a target luminous intensity of the external light source.

[0040] For example, the light sensor detects and analyzes the light sources in the external environment of the vehicle, and the final output result is the target luminous intensity of these external light sources. Luminous intensity is a physical quantity that describes the luminous ability of a light source in a specific direction, and the unit is candela (cd). Obtaining the target luminous intensity means that the light sensor converts the detected light information into a quantifiable luminous intensity value through its internal photoelectric conversion mechanism and signal processing algorithm. This value is the target luminous intensity.

[0041] S120. Determine a target transmittance corresponding to the target luminous intensity according to a preset corresponding relationship between the luminous intensity of the external light source and the transmittance of the windshield, wherein the luminous intensity and the transmittance are negatively correlated.

[0042] Exemplarily, based on the preset correspondence between the luminous intensity of the external light source and the transmittance of the windshield, the target transmittance corresponding to the target luminous intensity is determined. The luminous intensity and the transmittance are negatively correlated, which means that when the luminous intensity of the external light source increases, the transmittance of the windshield will decrease accordingly; conversely, when the luminous intensity of the external light source decreases, the transmittance of the windshield will increase. Specifically, when a target luminous intensity of an external light source is obtained, based on the preset correspondence between the luminous intensity of the external light source and the transmittance of the windshield, the target luminous intensity of the external light source obtained is matched with the corresponding target transmittance, wherein the greater the target luminous intensity, the lower the target transmittance matched thereto.

[0043] For example, in a strong light environment, in order to prevent excessive light from directly entering the car and affecting the driver's vision, the windshield needs a lower light transmittance; in a weak light environment, the windshield needs a higher light transmittance to ensure that the driver can see clearly outside the car.

[0044] S130: Adjust the light transmittance of the windshield to the target light transmittance.

[0045] For example, after obtaining the target transmittance corresponding to the target luminous intensity, in order to avoid excessive light interfering with the driver or too dark light limiting the driver's vision, the transmittance of the current vehicle windshield needs to be adjusted to the target transmittance.

[0046] Specifically, the car screen is specially equipped with an automatic adjustment switch and a manual adjustment switch for adjusting the light transmittance of the front windshield, which is convenient for the driver to control the light transmittance of the front windshield according to different needs. The automatic adjustment switch is a control button that realizes the automatic adjustment function of the light transmittance of the front windshield. When this switch is turned on, the target light intensity of the external light source is matched with the corresponding target light transmittance according to the preset correspondence between the light intensity of the external light source and the light transmittance of the windshield, and the light transmittance of the front windshield is automatically adjusted according to the target light transmittance to provide the most suitable driving visual environment. This automatic adjustment function is designed to provide convenience for drivers, so that they do not need to adjust the light transmittance frequently manually, ensuring safety and comfort during driving. The manual adjustment switch is to manually adjust the light transmittance of the windshield directly based on the target light transmittance in order not to affect the driver's travel after the automatic adjustment switch fails.

[0047] When the automatic adjustment switch is turned on, the manual adjustment switch becomes gray and unavailable, preventing the driver from accidentally operating the manual adjustment switch during the automatic adjustment mode, which would interfere with the normal operation of the automatic adjustment function. This design helps ensure the stability and reliability of the windshield glass transmittance adjustment system, providing the driver with a clear and comfortable driving field of view while avoiding potential safety risks caused by confusing operations.

[0048] In summary, the method for preventing vehicle light glare proposed in the embodiment of the present application determines the target transmittance corresponding to the target luminous intensity through a preset correspondence between the luminous intensity of the external light source and the transmittance of the windshield. The recognition accuracy is guaranteed, the external light source can be detected more accurately, and the transmittance requirements under different light intensities can be met, thereby avoiding severe visual interference to the driver in an instant.

[0049] In some examples, the steps before detecting the external light source of the vehicle based on the light sensor and obtaining the target luminous intensity of the external light source include:

[0050] When the vehicle is powered on, a self-test is performed on the automatic light transmittance adjustment function of the windshield to obtain a self-test result;

[0051] When the self-test result indicates that a fault exists, the fault light of the vehicle is controlled to light up and a voice announcement is made to prompt the driver to switch the windshield from the automatic light transmittance adjustment mode to the manual light transmittance adjustment mode.

[0052] For example, each time the vehicle is powered on, the windshield will perform a self-test. During this process, the light transmittance of the windshield will change in a specific way, gradually increasing from the initial 40% to 100%. Through this gradual change in light transmittance, the working conditions of the windshield light transmittance adjustment device under different light transmittance values ​​can be fully tested. When the light transmittance reaches 100%, the entire self-test process ends and the self-test results are obtained. The system will determine whether the windshield is operating normally based on the data and feedback information collected during this process.

[0053] If after the above self-check process, the self-check result is a fault, then the indicator light corresponding to the corresponding fault on the vehicle dashboard will light up to indicate the approximate location of the fault to the driver. At the same time, the voice prompt system will play a targeted prompt message to inform the driver that there is a fault in the windshield transmittance adjustment mechanism, and clearly remind the driver to turn off the automatic transmittance adjustment function and set the transmittance manually to ensure that in the event of failure of the automatic adjustment function, the driver can still adjust the windshield glass transmittance according to the actual situation to ensure driving comfort and safety.

[0054] In some examples, the external light sources include high beams and low beams of oncoming vehicles and vehicles traveling in the same direction as the vehicle.

[0055] Exemplarily, when a vehicle is driving, the external light sources it faces include the high beams and low beams of the oncoming vehicles and vehicles in the same direction. When driving at night, and the oncoming vehicle is approaching, the high beam or low beam of the oncoming vehicle will generate light. The high beam will directly hit the driver's eyes due to the high luminous intensity, causing glare and affecting the driver's driving vision, so it is an important external light source factor that needs to be considered. The low beam will also have an impact in certain scenes. These lights are part of the external light source for the vehicle; when driving at night, whether the vehicle in the same direction turns on the high beam or low beam, the light it emits will also affect the vehicle. For example, when the vehicle in the same direction in front turns on the high beam, the light will be reflected into the eyes of the driver of the vehicle through the road surface, rearview mirror, etc., interfering with his normal driving vision; and the low beam will also affect the driver's judgment of the road conditions ahead in some cases. These lights of vehicles of different types and directions will have different degrees of impact on the driver's vision under different road conditions and driving scenarios, and are external light factors that need to be focused on in the vehicle operation environment.

[0056] In some examples, the target light transmittance includes a first light transmittance, a second light transmittance, and a third light transmittance, the first light transmittance is greater than the second light transmittance, and the second light transmittance is greater than the third light transmittance;

[0057] The step of determining the target light transmittance corresponding to the target light intensity according to the preset corresponding relationship between the light intensity of the external light source and the light transmittance of the windshield glass comprises:

[0058] When the luminous intensity is less than a first preset threshold, the target transmittance is the first transmittance;

[0059] When the luminous intensity is greater than a first preset threshold and less than a second preset threshold, the target light transmittance is the second light transmittance;

[0060] When the luminous intensity is greater than a second preset threshold, the target transmittance is the third transmittance, and the second preset threshold is greater than the first preset threshold.

[0061] Exemplarily, when the luminous intensity of the detected external light source (such as the light of the oncoming vehicle or the same-direction vehicle) is low and is less than the pre-set first preset threshold, it means that the ambient light is relatively dark or under natural light conditions. In this case, in order to ensure that the driver can have a clear enough view to see the road and the surrounding environment, the windshield needs a higher light transmittance, so that more light can pass through the windshield into the car, so that the driver can better observe the external situation. Therefore, in this case, the target light transmittance of the windshield is set to the first light transmittance. Among them, the first preset threshold is 10000cd (lumens / cdela), the first light transmittance is 100%, and the first light transmittance is relatively high to ensure that enough light passes through the windshield into the car, so that the driver can clearly observe the road conditions.

[0062] When the luminous intensity of the external light source increases and exceeds the first preset threshold but has not reached the second preset threshold, the light intensity is at a medium level. At this time, the oncoming vehicle may have turned on the low beam, causing the luminous intensity of the external light source to increase. In order to avoid excessive light causing discomfort to the driver's eyes while ensuring that a certain amount of light enters the car, the target transmittance of the windshield will be adjusted to the second transmittance, where the second preset threshold is 14000cd (lumens / candela) and the second transmittance is 80%. Generally speaking, the second transmittance will be lower than the first transmittance to appropriately reduce the amount of light entering the car and maintain visual comfort and clarity. The second transmittance can block some of the strong light while allowing an appropriate amount of light to enter the car to maintain a good visual effect.

[0063] If the luminous intensity of the external light source is very high and greater than the second preset threshold, for example, the oncoming vehicle turns on the high beam and is close to the vehicle, in this case, the excessive light will seriously interfere with the driver's vision and even cause glare, affecting driving safety. In order to protect the driver's eyes and reduce the impact of glare, the target transmittance of the windshield will be set to the third transmittance, where the third transmittance is 50%. Usually, the third transmittance is the lowest of the three. By significantly reducing the transmittance, the strong light entering the car is reduced, ensuring that the driver can drive safely under relatively comfortable lighting conditions.

[0064] In some examples, the light sensor has a light-sensitive material that includes indium gallium arsenide.

[0065] Exemplarily, the photosensitive material in the optical sensor is the core part of the optical sensor to realize its function. It has the special property of responding to light, can absorb photons and generate electrical effects through internal physical mechanisms, thereby converting optical signals into electrical signals, which are then processed and used by subsequent circuits. The photosensitive material is specifically indium gallium arsenide. Indium gallium arsenide is a compound semiconductor material composed of elements such as indium (In), gallium (Ga), and arsenic (As). It has unique photoelectric properties, such as a high absorption coefficient and photoelectric conversion efficiency for light in a specific wavelength range, which makes the photosensitive material based on indium gallium arsenide perform well in detecting light within a specific spectral range, and can accurately sense light signals of different intensities, which provides strong support for optical sensors to achieve high-sensitivity and high-precision light detection functions, and is widely used in various fields that require accurate detection of light.

[0066] Indium gallium arsenide (InGaAs) has excellent optoelectronic properties in the near-infrared to mid-infrared band (0.9-2.6μm), and its sensitivity is higher than that of silicon and germanium in this band. Its band gap can be optimized by adjusting the ratio of indium (In) and gallium (Ga) to meet different application requirements. In addition, the light sensor made of InGaAs material has low dark current and fast response speed, which can realize the detection of high-speed light signals. It can also increase the contact area of ​​the light source that the light sensor can detect, and can cover a wider spatial range, so that the light sensor has a better reception effect on light from different directions, so as to achieve the purpose of more accurate detection data.

[0067] In some examples, the step of adjusting the light transmittance of the windshield to the target light transmittance includes:

[0068] In the case of manually adjusting the transmittance, obtaining a user's voice command, and adjusting the transmittance of the windshield to the target transmittance based on the voice command;

[0069] In the case of automatically adjusting the light transmittance, the light transmittance of the windshield is adjusted to the target light transmittance.

[0070] For example, after the automatic adjustment function of the windshield's light transmittance is self-checked, if the self-check result is a fault, the driver needs to switch the automatic adjustment of the light transmittance to the manual adjustment of the light transmittance. In the case of manual adjustment of the light transmittance, the light transmittance of the windshield can be adjusted by voice adjustment, such as issuing a voice command "Set the windshield transmittance to 80%", and the voice reply is "OK, the current glass transmittance is set to 80%". This avoids manual operation by the driver while driving the vehicle, which brings certain safety hazards. In the case of automatic adjustment of the light transmittance, after obtaining the target transmittance corresponding to the target luminous intensity, the light transmittance of the current vehicle's windshield is automatically adjusted to the target transmittance. No manual intervention by the user is required, and the entire process is completed automatically, aiming to provide the driver with a convenient and suitable driving environment.

[0071] In some examples, the step of performing a self-test on the automatic adjustment function of the light sensor and the windshield when the vehicle is powered on and obtaining the self-test result includes:

[0072] When the self-test result is that there is no fault, obtaining distance information between the vehicle and vehicles within a preset range;

[0073] When the distance information is less than a preset safety threshold and the vehicle speed has not decreased, the vehicle is controlled to decelerate until it stops.

[0074] For example, when the vehicle is powered on, it will first perform a self-check on the automatic adjustment function of the windshield and obtain the self-check result. This step is an important part of ensuring that the key functions of the vehicle are in normal working condition. Only when the self-check result shows that there is no fault, the vehicle will continue to perform subsequent operations. This is to ensure that in the subsequent process based on sensor data and function operation, no abnormal situation will occur due to potential faults in the early stage, ensuring the stability and reliability of the entire system.

[0075] After confirming that the self-test result is not a fault, the vehicle begins to obtain distance information from other vehicles within the preset range. This preset range is a reasonable area set according to the actual use scenario and safety requirements of the vehicle to determine the surrounding vehicles that need to be paid special attention to. Obtaining distance information usually relies on various sensors equipped on the vehicle, such as millimeter wave radar, ultrasonic sensor or camera, which can accurately measure the distance between the vehicle and surrounding vehicles.

[0076] After obtaining the distance information, the distance information will be compared with the preset safety threshold, while monitoring the vehicle's speed. The preset safety threshold is a distance value determined based on multiple factors such as vehicle driving characteristics and braking performance. It represents the minimum safety distance required for the vehicle to maintain safe driving under the current driving state.

[0077] When the distance information is less than the preset safety threshold and the vehicle's speed has not decreased, it means that the distance between the vehicle and the surrounding vehicles is very close, and no deceleration measures have been taken to increase the safety distance, and there is a risk of collision. In order to avoid possible collision accidents and ensure driving safety, the vehicle control system will automatically intervene and control the vehicle to decelerate until the vehicle stops completely. This automatic deceleration and parking control mechanism is an important part of the vehicle safety system. It can take proactive measures to reduce the risk and harm of collision when the driver fails to respond in time or operates improperly, thereby maximizing the safety of occupants and vehicles.

[0078] The data transmission scheme was adjusted from LIN-CAN to SOME / IP. LIN (Local Interconnect Network) and CAN (Controller Area Network) are commonly used communication protocols in vehicles. SOME / IP (Scalable service-Oriented Middleware over IP) is a service-oriented communication protocol based on IP, and Ethernet is a widely used high-speed local area network technology. The communication rate of Ethernet is much higher than that of CAN, which can increase the rate from recognition to execution, avoiding the whole process taking a long time, causing the driver to not be able to see the road ahead and causing traffic accidents. Using higher communication rates to optimize the response speed of vehicle systems, reduce potential safety risks, and meet the needs of modern smart cars for efficient and real-time data transmission.

[0079] In summary, this application retains the original state of the vehicle, does not require additional equipment, and does not block the driver's field of view. Supports voice adjustment to ensure driving safety. The transmittance can be flexibly adjusted from 50% to 100% to adapt to various light conditions. It has power-on self-check logic and will actively prompt when the system fails. When using related functions, the forward collision warning will be forced to turn on to ensure driving safety. In addition, we are constantly optimizing the detection light source, committed to shortening the detection time and improving the detection accuracy.

[0080] like Figure 2 As shown, the present application proposes a system for preventing vehicle light glare, the system comprising: a data detection module 21, a data determination module 22 and a data setting module 23;

[0081] The data detection module 21 is configured to: detect the external light source of the vehicle based on the light sensor to obtain the target luminous intensity of the external light source;

[0082] The data determination module 22 is configured to: determine the target light transmittance corresponding to the target light intensity according to a preset corresponding relationship between the light intensity of the external light source and the light transmittance of the windshield, wherein the light intensity and the light transmittance are negatively correlated;

[0083] The data setting module 23 is configured to adjust the light transmittance of the windshield to the target light transmittance.

[0084] In some examples, the steps before detecting the external light source of the vehicle based on the light sensor and obtaining the target luminous intensity of the external light source include:

[0085] When the vehicle is powered on, a self-test is performed on the automatic light transmittance adjustment function of the windshield to obtain a self-test result;

[0086] When the self-test result indicates that a fault exists, the fault light of the vehicle is controlled to light up and a voice announcement is made to prompt the driver to switch the windshield from the automatic light transmittance adjustment mode to the manual light transmittance adjustment mode.

[0087] In some examples, the external light source further includes high beams and low beams of vehicles on the opposite direction and vehicles in the same direction as the vehicle.

[0088] In some examples, the target light transmittance includes a first light transmittance, a second light transmittance, and a third light transmittance, the first light transmittance is greater than the second light transmittance, and the second light transmittance is greater than the third light transmittance;

[0089] The step of determining the target light transmittance corresponding to the target light intensity according to the preset corresponding relationship between the light intensity of the external light source and the light transmittance of the windshield glass comprises:

[0090] When the luminous intensity is less than a first preset threshold, the target transmittance is the first transmittance;

[0091] When the luminous intensity is greater than a first preset threshold and less than a second preset threshold, the target light transmittance is the second light transmittance;

[0092] When the luminous intensity is greater than a second preset threshold, the target transmittance is the third transmittance, and the second preset threshold is greater than the first preset threshold.

[0093] In some examples, the light sensor has a light-sensitive material that includes indium gallium arsenide.

[0094] In some examples, the step of adjusting the light transmittance of the windshield to the target light transmittance includes:

[0095] In the case of manually adjusting the transmittance, receiving a user instruction, and adjusting the transmittance of the windshield to the target transmittance based on the user instruction; or, in the case of automatically adjusting the transmittance, adjusting the transmittance of the windshield to the target transmittance.

[0096] In some examples, the step of performing a self-test on the automatic adjustment function of the light sensor and the windshield when the vehicle is powered on and obtaining the self-test result includes:

[0097] When the self-test result is that there is no fault, obtaining distance information between the vehicle and vehicles within a preset range;

[0098] When the distance information is less than a preset safety threshold and the vehicle speed has not decreased, the vehicle is controlled to decelerate until it stops.
