[0002] With the rapid development of the automobile industry and the continuous growth of the number of cars, vehicle driving safety has become the focus of social attention. Under low visibility conditions such as night, fog, and rain, vehicle headlights are the main lighting tool, and the adjustment of their brightness has an important impact on driving safety.

[0003] At present, some vehicle drivers manually control the headlight switch, while other vehicles equipped with brightness sensors use the brightness sensors to provide information to automatically switch the vehicle headlights.

[0004] But no matter which one, it only controls the on and off of the headlights, but does not adjust the brightness of the headlights, and always maintains the maximum brightness output. Under good lighting conditions, if the headlights still maintain the maximum brightness output, it may cause a dazzling effect and affect the vision of other road users. In addition, headlights working at maximum brightness will consume more electricity, which will increase the energy consumption of the vehicle. Summary of the invention

[0005] In view of this, the present invention provides a light brightness adjustment method, device, system, equipment, storage medium and program product to solve the problem of maintaining maximum brightness output. Under good lighting conditions, if the headlights still maintain maximum brightness output, it may cause a dazzling effect and affect the vision of other road users. In addition, the headlights will consume more electricity when working at maximum brightness, which will increase the energy consumption of the vehicle.

[0006] In a first aspect, the present invention provides a method for adjusting light brightness, the method comprising: obtaining current environmental information of a vehicle; determining a target light brightness of the vehicle headlights based on the current environmental information of the vehicle; and adjusting the vehicle headlights from a current brightness to a target light brightness based on a preset adjustment mode.

[0007] The light brightness adjustment method provided in this embodiment can more accurately determine the required lighting level by sensing the vehicle's environmental information (such as light intensity, weather conditions, road conditions, etc.) in real time. In low visibility conditions such as night, fog or rain, appropriately increasing the headlight brightness can expand the driver's field of vision and improve the accuracy of road recognition, thereby effectively reducing traffic accidents caused by unclear vision.

[0008] In addition, adjusting the brightness of vehicle headlights based on different environmental information can effectively reduce energy consumption.

[0009] In an optional embodiment, the adjustment mode includes: a local adjustment mode and / or an overall lighting mode, and the vehicle headlights include multiple LED arrays; wherein, based on a preset adjustment mode, the vehicle headlights are adjusted from a current brightness to a target light brightness, including: when the adjustment mode is a local adjustment mode, based on the light brightness of the vehicle headlights, determining data information of the LEDs in the LED array; wherein the data information includes a target position and a target number; based on the target position and the target number, determining a target LED from multiple LED arrays, and adjusting the target LED from a current brightness to a target light brightness; when the adjustment mode is an overall lighting mode, based on the target light brightness of the vehicle headlights, adjusting multiple LED arrays from a current brightness to a target light brightness.

[0010] The light brightness adjustment method provided in this embodiment can be flexibly adjusted according to different road conditions and driving needs through the local adjustment mode. For example, when driving on a curve, the brightness of the LED on the inside of the curve can be increased to provide a better lighting effect for the curve.

[0014] The light brightness adjustment method provided in this embodiment allows the user to directly select the target mode through a confirmation operation. This strategy gives the user more control and personalized choices. The user can flexibly switch between the local adjustment mode and the overall lighting mode according to their needs and preferences, thereby improving the driving experience.

[0015] In addition, by properly selecting the adjustment mode, this strategy helps achieve the goal of energy saving and high efficiency. When full lighting is not required, selecting the local adjustment mode can reduce unnecessary power consumption; when high-brightness lighting is required, the overall lighting mode is used to ensure the lighting effect while avoiding the increase in energy consumption and shortened life caused by excessive work of a single LED.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] Based on relevant technologies, it can be known that with the rapid development of the automobile industry and the continuous growth of the number of cars, vehicle driving safety has become the focus of social attention. Under low visibility conditions such as night, fog, and rain, vehicle headlights are the main lighting tool, and the adjustment of their brightness has an important impact on driving safety.

[0030] With the rapid development of the automobile industry and the continuous growth of the number of cars, vehicle driving safety has become the focus of social attention. Under low visibility conditions such as night, fog, and rain, vehicle headlights are the main lighting tool, and the adjustment of their brightness has an important impact on driving safety.

[0031] At present, some vehicle drivers manually control the headlight switch, while other vehicles equipped with brightness sensors use the brightness sensors to provide information to automatically switch the vehicle headlights.

[0032] But no matter which one, it only controls the on and off of the headlights, but does not adjust the brightness of the headlights, and always maintains the maximum brightness output. Under good lighting conditions, if the headlights still maintain the maximum brightness output, it may cause a dazzling effect and affect the vision of other road users. In addition, headlights working at maximum brightness will consume more electricity, which will increase the energy consumption of the vehicle.

[0033] The present invention provides a method for adjusting the brightness of lights, which can more accurately determine the required lighting level by sensing the environmental information of the vehicle in real time (such as light intensity, weather conditions, road conditions, etc.). In low visibility conditions such as night, fog or rain, appropriately increasing the brightness of the headlights can expand the driver's field of vision and improve the accuracy of road recognition, thereby effectively reducing traffic accidents caused by unclear vision.

[0034] In addition, adjusting the brightness of vehicle headlights based on different environmental information can effectively reduce energy consumption.

[0035] The present invention provides a light brightness adjustment system, which includes: a sensor for acquiring current environmental information of a vehicle; a data source processor for determining the target light brightness of the vehicle headlights based on the current environmental information of the vehicle, and adjusting the vehicle headlights from the current brightness to the target light brightness based on a preset adjustment mode.

[0036] Combination Figure 1 As shown, the sensor may include a light sensor and a camera, wherein the light sensor and the camera obtain current environmental information of the vehicle, and the data source processor determines the target light brightness of the vehicle headlights based on the current environmental information of the vehicle, and adjusts the vehicle headlights from the current brightness to the target light brightness based on a preset adjustment mode.

[0037] According to an embodiment of the present invention, an embodiment of a method for adjusting light brightness is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0038] In this embodiment, a method for adjusting light brightness is provided, which can be used in the above-mentioned light brightness adjustment system. Figure 2 FIG. 1 is a flow chart of a method for adjusting light brightness according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0039] Step S101, obtaining the current environment information of the vehicle.

[0040] The current environmental information may be light intensity, weather conditions, time information, road type, traffic status, etc., which are not specifically limited here. Specifically, a variety of sensors built into the vehicle can be used for direct measurement. External data sources (such as weather APIs, traffic information platforms) can also be connected to obtain real-time data, which are not specifically limited here and can be implemented by those skilled in the art. For example: On a rainy night, the vehicle's light sensor detects that the light intensity is extremely low, and the GPS shows that it is currently located on the main road of the city, and the Internet of Vehicles data shows that the traffic flow on this section is large.

[0041] Preferably, in addition to obtaining the ambient light conditions of the vehicle through the illumination sensor as the basis for adjusting the brightness of the headlights, the brightness of the target in front of the vehicle can also be analyzed by the on-board forward camera to determine which areas of the LED in the LED array should be lit. For example: there are street lights on the road section where the vehicle is currently traveling, so the ambient light around the vehicle is relatively good, but the street lights suddenly disappear a few dozen meters ahead. Then, after the camera collects and analyzes the image, it can guide the control module to increase the brightness to ensure that the target in front can be seen clearly. Or the target in front is generally within the illumination range of the ambient light, and half is in the shadow. Through image analysis, the LED of the headlight can be controlled to be partially adjusted, and the brightness of the headlight part is increased so that the target in the shadow can be seen clearly, while the LED in the area where the headlight illuminates the target with better brightness can output a slightly lower brightness.

[0042] Step S102, determining the target light brightness of the vehicle headlights based on the current environment information of the vehicle.

[0043] The target light brightness can be used to characterize the brightness of the vehicle headlights adapted to the current environmental information. The target light brightness can be A, B, etc., which is not specifically limited here. Specifically, according to the environmental information collected in step S101, the headlight brightness that best suits the current environment is determined through a preset algorithm or logical judgment. For example, when the light is extremely weak and the road conditions are complex, it may be necessary to adjust the headlights to the highest brightness to increase visibility; on clear nights or on roads with street lights in the city, the brightness can be appropriately reduced to reduce interference with other road users. For example: On the above-mentioned rainy night, the system determines that the headlight brightness is the maximum brightness.

[0044] Step S103, based on a preset adjustment mode, adjusting the vehicle headlights from the current brightness to the target light brightness.

[0045] The adjustment mode can refer to the way of controlling the brightness change of the headlights. The adjustment mode can be a local adjustment mode, an overall lighting mode, etc., which are not specifically limited here. Specifically, once the target light brightness is determined, the headlights will be adjusted from the current brightness to the target brightness according to the preset adjustment mode. This helps to avoid sudden brightness changes causing discomfort to the driver and other road users.

[0046] The light brightness adjustment method provided in this embodiment can more accurately determine the required lighting level by sensing the vehicle's environmental information (such as light intensity, weather conditions, road conditions, etc.) in real time. In low visibility conditions such as night, fog or rain, appropriately increasing the headlight brightness can expand the driver's field of vision and improve the accuracy of road recognition, thereby effectively reducing traffic accidents caused by unclear vision.

[0047] In addition, adjusting the brightness of vehicle headlights based on different environmental information can effectively reduce energy consumption.

[0048] In an optional embodiment, the adjustment mode includes: a local adjustment mode and / or an overall lighting mode, and the vehicle headlight includes a plurality of light emitting diode arrays; wherein step S103 includes:

[0049] Step a1, when the adjustment mode is the local adjustment mode, the data information of the light emitting diodes in the light emitting diode array is determined based on the light brightness of the vehicle headlights; wherein the data information includes the target position and the target quantity.

[0050] In the local adjustment mode, the specific information of the light-emitting diodes (LEDs) that need to be activated is determined based on the current light brightness requirements of the vehicle headlights, including which LEDs need to be lit (target position) and how many LEDs need to be lit (target number). Specifically, one or more brightness thresholds can be set, and the number of LEDs that need to be lit is determined based on the comparison results between the current brightness of the vehicle headlights and the thresholds. The optimal number and position of LEDs can also be dynamically calculated through an algorithm based on real-time data such as ambient light, vehicle speed, and steering angle. No specific limitations are made here, and it can be implemented by those skilled in the art. The vehicle headlights need to slightly increase the brightness of the left area to cope with the lighting of the curve. It can be decided to light up the first 5 LEDs in the left LED array to improve the lighting effect of this area.

[0051] Specifically, the above step a1 includes:

[0052] Step a11, determining a target number of light emitting diodes in the light emitting diode array based on the light brightness of the vehicle headlights.

[0053] Based on the light brightness requirement of the vehicle headlights, the number of LEDs that need to be lit is calculated. Specifically, the headlight brightness requirement can be mapped to the number of LEDs. For example, a certain number of LEDs is added for each increase in brightness. The LED brightness superposition effect can also be taken into account, and a nonlinear function can be used to calculate the number of LEDs to achieve more precise brightness control, etc. This is not specifically limited here and can be implemented by those skilled in the art.

[0054] Step a12, determining the target position of the LEDs in the LED array based on the number of LEDs in the LED array and a preset tuning mode.

[0055] After determining the number of LEDs that need to be lit, the specific positions of these LEDs in the array are determined according to a preset tuning mode (such as uniform distribution, concentration in a specific area, etc.). Specifically, the LEDs can be evenly distributed in the array to achieve a wider range of lighting. It is also possible to concentrate the LEDs in a specific area according to lighting needs, such as concentrating on one side of the vehicle when lighting a curve. It is also possible to dynamically adjust the position of the LEDs according to the driving state of the vehicle (such as turning, accelerating, etc.), etc., which is not specifically limited here and can be implemented by those skilled in the art.

[0056] Step a2, determining a target LED from a plurality of LED arrays based on the target position and the target quantity, and adjusting the target LED from a current brightness to a target light brightness.

[0057] According to the target position and target number determined in step a1, a target LED is determined from multiple LED arrays; wherein the target LED is a LED that needs to be adjusted in brightness, and then the target LED is adjusted from the current brightness to the target light brightness. For example: the current brightness is 25%, the target light brightness is 50%, and the target LED is adjusted from the current brightness to the target light brightness by adjusting the target LED. Specifically, the light brightness can be adjusted by changing the duty cycle of the LED; the brightness can also be changed by directly controlling the current passing through the LED, etc., which is not specifically limited here and can be implemented by those skilled in the art.

[0058] Step a3, when the adjustment mode is the overall lighting mode, based on the target light brightness of the vehicle headlights, the plurality of light emitting diode arrays are adjusted from the current brightness to the target light brightness.

[0059] In the overall lighting mode, the local lighting needs are not considered, but the brightness of the entire LED array is uniformly adjusted to the target light brightness. Specifically, the brightness of all LEDs can be adjusted at the same time through a unified control signal; the LED array can also be divided into multiple areas, and the brightness of each area can be controlled separately, but in this mode, the brightness of all areas is set to the same, etc., which is not specifically limited here and can be implemented by those skilled in the art.

[0060] The light brightness adjustment method provided in this embodiment can be flexibly adjusted according to different road conditions and driving needs through the local adjustment mode. For example, when driving on a curve, the brightness of the LED on the inside of the curve can be increased to provide a better lighting effect for the curve. In the overall lighting mode, the driver does not need to manually adjust the brightness of each LED array. The system will automatically complete all adjustments, thereby simplifying the driving operation. In addition, the overall lighting mode can significantly improve the driver's field of vision under low visibility conditions and reduce the risk of traffic accidents caused by unclear vision.

[0061] In addition, by accurately calculating the number of LEDs required, it can be ensured that the headlights achieve the predetermined brightness requirements without wasting energy due to over-illumination or causing unnecessary glare to other road users.

[0062] In an optional embodiment, the above method further includes:

[0063] Step b1, in response to a confirmation operation of the target object, determining a target mode from the adjustment modes.

[0064] Specifically, the user confirms or selects a specific adjustment mode as the target mode through some means (such as buttons, touch screens, voice commands, etc.). The target object can be a driver, a passenger, or a system automation process.

[0065] Preferably, a dedicated button or knob is provided inside the vehicle, and the user can select different adjustment modes by rotating or pressing. Different adjustment mode options are displayed through the vehicle touch screen, and the user can confirm the selection by touching the icon or menu item on the screen. The vehicle supports a voice assistant function, and the user can select the adjustment mode through voice commands. In some cases, the system may automatically select the target mode according to the current environment, driving conditions or user habits.

[0066] In an optional embodiment, the above method further includes:

[0067] Step b2, detecting whether the target light brightness of the vehicle headlights is within a preset brightness range.

[0068] Detect whether the target brightness of the vehicle headlights set by the user or automatically calculated by the system is within a preset brightness range. This range may be set based on various factors such as safety standards, road regulations, driving environment, etc. Among them, the preset brightness range can be (10% to 50%), or (20% to 40%), etc.

[0069] Step b3: if the target light brightness of the vehicle headlight is within a preset brightness range, determining that the adjustment mode is a local adjustment mode.

[0070] If the system detects that the target light brightness of the vehicle headlights is within the preset brightness range, the system believes that the current lighting needs do not require a significant adjustment of the entire headlight array, so it selects the local adjustment mode and only fine-tunes some LEDs to meet the lighting needs of a specific area. For example: when driving on a highway at night, the user sets a lower target brightness to reduce the glare to other vehicles. The system detects that the brightness value is within the preset nighttime highway brightness range, so it determines to use the local adjustment mode and only fine-tune the LEDs at the edge of the headlights to increase the illumination range of the high beam.

[0071] Step b4: if the target light brightness of the vehicle headlights is not within the preset brightness range, determining that the adjustment mode is the overall lighting mode.

[0072] If the system detects that the target brightness of the vehicle's headlights is not within the preset brightness range, it means that the current lighting needs are special or extreme, and the entire headlight array needs to be significantly adjusted to meet the needs. Therefore, the system selects the overall lighting mode and uniformly adjusts all LEDs in the headlights to achieve the target brightness. When driving on rural roads at night, users set a higher target brightness in order to see obstacles and road conditions in the distance. The system detects that the brightness value exceeds the preset brightness range, so it determines to use the overall lighting mode to adjust all LEDs in the headlights to a higher brightness level to improve the lighting effect.

[0073] The light brightness adjustment method provided in this embodiment allows the user to directly select the target mode through a confirmation operation. This strategy gives the user more control and personalized choices. The user can flexibly switch between the local adjustment mode and the overall lighting mode according to their needs and preferences, thereby improving the driving experience.

[0074] In addition, by properly selecting the adjustment mode, this strategy helps achieve the goal of energy saving and high efficiency. When full lighting is not required, selecting the local adjustment mode can reduce unnecessary power consumption; when high-brightness lighting is required, the overall lighting mode is used to ensure the lighting effect while avoiding the increase in energy consumption and shortened life caused by excessive work of a single LED.

[0075] In an optional implementation, the above step a11 includes:

[0076] Step a111, obtaining the current number of light emitting diodes in the light emitting diode array.

[0077] Read or determine the number of LEDs currently in use in a light emitting diode (LED) array. This is usually accomplished through system configuration, hardware interfaces, or pre-stored data. The current number can be used to characterize the number of LEDs currently being illuminated.

[0078] Step a112, determining a first number of LEDs in the LED array based on the light brightness of the vehicle headlights; wherein the first number is the number of LEDs that need to be adjusted at the light brightness.

[0079] According to the brightness of the vehicle headlight, the number of LEDs required for lighting according to the current brightness can be determined. The first number is the number of LEDs that need to be adjusted at the brightness. For example, if the target brightness of the vehicle headlight is medium intensity, according to the brightness mapping table or algorithm calculation, 40 LEDs may need to be activated to achieve this brightness, then the first number is 40.

[0080] Step a113, determining a target quantity based on the difference between the first quantity and the current quantity.

[0081] If the first number is less than the current number, the target number is the first number itself; if the first number is greater than the current number, if the LED array cannot add more LEDs, then the brightness of the existing LEDs may need to be adjusted. If the first number is greater than the current number and it is not possible to add LEDs, the brightness of the current LEDs may be adjusted to a higher level to simulate the lighting effect of more LEDs.

[0082] For example, if the current number of LEDs is 64, and 40 LEDs (the first number) need to be activated to achieve the target brightness, the target number is actually 40, because there is no need to reduce the number of existing LEDs. However, if the first number is 80, and the current number of LEDs in the array is 64, 16 LEDs can be added for lighting.

[0083] Preferably, the vehicle's headlights are composed of 100 LED arrays. Under the current external brightness conditions, the brightness of 30 LEDs (30 LEDs scattered in the matrix surface) is appropriate. Under the next ambient brightness conditions, the total brightness of 35 LEDs is appropriate. Then the added 5 LEDs should also be evenly added in the LED matrix surface to avoid a sudden increase in brightness at a certain local point. And because the change in ambient brightness generally does not change suddenly, the increase or decrease in the number of LEDs lit for brightness adjustment is also gradually fine-tuned, and there should not be several abrupt gears, such as 30 LEDs are currently lit, and the next moment it immediately becomes 60 LEDs, causing a sudden change in brightness in the macro sense.

[0084] The light brightness adjustment method provided in this embodiment can flexibly adjust the number of light emitting diodes according to the actual light brightness requirements of the vehicle headlights. Whether it is necessary to increase the brightness to enhance the lighting effect, or to reduce the brightness to save energy or avoid glare, it can be achieved by adjusting the number of LEDs.

[0085] In this embodiment, a light brightness adjustment device is also provided, which is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made are omitted. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function.
