Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a method, device, vehicle, and storage medium for controlling high beam headlights. Background Technology

[0002] With advancements in lighting technology, the advent of LEDs has enabled vehicle headlights to be smaller and more aesthetically pleasing. Furthermore, LEDs can be locally controlled via the vehicle's control signals, creating an adaptive high beam system. This system intelligently identifies vehicles ahead and activates or deactivates the high beams in the corresponding areas, preventing glare for drivers and achieving an anti-glare function.

[0003] In existing technologies, adaptive high beams, in order to ensure that the high beam system has an acceptable response speed under any circumstances, control the switching on and off of the high beams at the maximum speed required by the system. This results in drastic changes in the brightness of the lights, causing a strong flickering sensation for the driver and posing a safety hazard.

[0004] Therefore, the current adaptive high beam headlights have problems such as abrupt changes in light, strong flickering, and potential safety hazards. Summary of the Invention

[0005] This application provides a high beam control method, device, vehicle, and storage medium. By dynamically adjusting the brightness gradient duration of the high beam in the current vehicle based on the current vehicle's speed, the target vehicle's position, and the target vehicle's movement speed, it ensures the high beam's on / off response speed and provides a smooth light gradient effect, achieving an anti-glare function. This solves the problems of abrupt light changes, strong flashing light, and potential safety hazards, thereby improving the user's driving experience at night.

[0006] In a first aspect, this application provides a high beam control method for current vehicles, the method comprising:

[0007] Get the current vehicle's speed, and get the target vehicle's speed and position;

[0008] Based on the location of the target vehicle, determine the light speed response zone to which the target vehicle belongs in each of the current vehicle's preset light speed response zones, and obtain the target light speed response zone;

[0009] The duration of the brightness transition of the high beam of the current vehicle is determined based on the target light speed response zone, the speed of the current vehicle, and the speed of the target vehicle.

[0010] The brightness adjustment amount for each brightness update cycle is determined based on the current brightness gradient duration and brightness update cycle of the vehicle's high beams.

[0011] The brightness of the high beams is adjusted according to the brightness adjustment amount in each brightness update cycle.

[0012] The technical solution of this application is applied to the current vehicle, obtaining the speed of the current vehicle and the speed and position of the target vehicle; determining the target vehicle's position within each preset light speed response zone of the current vehicle based on the target vehicle's position, thus obtaining the target light speed response zone; determining the brightness gradient duration of the current vehicle's high beams based on the target light speed response zone, the current vehicle's speed, and the target vehicle's speed; determining the brightness adjustment amount for each brightness update cycle based on the brightness gradient duration and brightness update cycle of the current vehicle's high beams; and adjusting the brightness of the high beams according to the brightness adjustment amount for each brightness update cycle. In the above technical solution, the target vehicle's position relative to the current vehicle is first used to determine the target light speed response zone. Then, based on the target light speed response zone, the target vehicle's speed relative to the current vehicle, and the current vehicle's speed, the duration of the high beam brightness transition (e.g., the duration of gradual brightening or fading) is determined. Based on the high beam brightness transition duration and a pre-set brightness update cycle, the required brightness adjustment amount for the high beam in each update cycle is determined. Finally, the high beam brightness is controlled based on the determined brightness adjustment amount, such as increasing or decreasing the high beam brightness. This achieves an anti-glare function and provides a smooth light transition effect, reducing the abruptness and flicker of light changes, lowering the risk of traffic accidents caused by drastic brightness changes, and solving the problems of abrupt light changes, strong flickering, and safety hazards associated with light changes, thereby improving the user's driving experience at night. Simultaneously, the target vehicle's target light speed response zone is determined based on its position relative to the current vehicle. Then, the duration of the high beam brightness transition for the current vehicle is determined based on the target vehicle's target light speed response zone, its speed relative to the current vehicle, and the current vehicle's speed. This allows for real-time dynamic adjustment of the high beam's brightness transition duration based on the target vehicle's position, ensuring a fast high beam on / off response and reducing the risk of traffic accidents caused by untimely light switching. This application dynamically adjusts the high beam brightness transition duration of the current vehicle based on the current vehicle's speed, the target vehicle's position, and its speed, ensuring a fast high beam on / off response while providing a smooth light transition effect. This achieves anti-glare functionality, reduces the abruptness and flicker of light changes, and solves the problems of abrupt light changes, strong flashing, and potential safety hazards, thereby improving the driving experience for users at night.

[0013] Secondly, this application provides a high beam control device for use in current vehicles, the device comprising:

[0014] The acquisition module is used to acquire the current vehicle's speed and the target vehicle's speed and position.

[0015] The first determining module is used to determine the light speed response zone to which the target vehicle belongs in each preset light speed response zone of the current vehicle based on the location of the target vehicle, and obtain the target light speed response zone.

[0016] The second determining module is used to determine the brightness gradient duration of the high beam of the current vehicle based on the target light speed response zone, the speed of the current vehicle, and the speed of the target vehicle.

[0017] The third determining module is used to determine the brightness adjustment amount for each brightness update cycle based on the brightness gradient duration and brightness update cycle of the current vehicle's high beams.

[0018] The control module is used to adjust the brightness of the high beams according to the brightness adjustment amount in each brightness update cycle.

[0020] At least one processor; and

[0021] A memory that is communicatively connected to at least one processor; wherein,

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0037] It should be noted that the terms "first," "second," "target," and "original," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein. Furthermore, the terms "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0038] Figure 1 This is a flowchart illustrating a high beam control method provided in this application. This embodiment can be applied to vehicles equipped with adaptive high beam controllers, where the brightness of the high beams needs to be dynamically adjusted when a target vehicle appears ahead. The high beam control method provided in this embodiment can be executed by the high beam control device provided in this application, which can be implemented through software and / or hardware. In a specific embodiment, the high beam control device can be integrated into the vehicle.

[0039] In one specific embodiment, the vehicle structure may be as follows: Figure 2 As shown, Figure 2 The vehicle shown includes an adaptive high beam controller 210, a camera 220, a body controller 230, a left high beam headlight 240, and a right high beam headlight 250.

[0040] The camera 220 is connected to the adaptive high beam controller 210 via a controller area network (CAN) bus. It is used to collect the position of the target vehicle in front of the current vehicle and the speed information of the target vehicle's position changing in the camera 220. The collected position and speed information of the target vehicle is then transmitted to the adaptive high beam controller 210 via the CAN bus.

[0041] The vehicle body controller 230 is connected to the adaptive high beam controller 210 via a CAN bus to detect the current driving status information of the vehicle, which may include the current vehicle speed, the on / off status of the low beam headlights, the on / off status of the high beam headlights, the ignition status of the engine, and the ambient light intensity information. The detected current driving status information of the vehicle is transmitted to the adaptive high beam controller 210 via the CAN bus.

[0042] The adaptive high beam controller 210 is connected to the left high beam 240 and the right high beam 250 via a CAN bus. It is used to determine whether to turn the high beam on or off and the brightness information of the LED beads of the high beam based on the target vehicle's position and speed information transmitted by the camera 220 and the current vehicle driving status information transmitted by the body controller 230. The brightness information is then transmitted to the left high beam 240 and the right high beam 250 via the CAN bus to form the actual adaptive high beam output.

[0043] The left high beam 240 and the right high beam 250 are used to receive the brightness information of the LED beads transmitted by the adaptive high beam controller 210, and change the brightness of the LED beads according to the brightness information.

[0044] The following is combined with Figure 2 The vehicle shown is used to illustrate the high beam control method provided in this application. The implementing entity of this method can be the adaptive high beam controller of the current vehicle. (Continue to refer to...) Figure 1 The high beam control method in this embodiment may specifically include the following steps:

[0045] S110. Obtain the current vehicle's speed and the target vehicle's speed and position.

[0046] Specifically, the current vehicle's speed refers to its traveling speed. The target vehicle is the vehicle located in front of the current vehicle, and its speed is its moving speed relative to the current vehicle, not its traveling speed. The target vehicle's position is its position relative to the current vehicle.

[0047] In practice, the body controller uses a speed sensor to acquire the current vehicle speed, or the speed sensor detects the current vehicle speed and actively transmits the detected speed to the body controller via the CAN bus. After receiving the current vehicle speed, the body controller transmits it to the adaptive high beam controller via the CAN bus. Simultaneously, the adaptive high beam controller uses a camera to acquire the position of the target vehicle relative to the current vehicle and the speed information of the target vehicle's position changing within the camera's view. The speed sensor, used to detect vehicle speed, has functions such as controlling computer input signals to control engine idling speed, automatic transmission torque converter lock-up, automatic transmission shifting, engine cooling fan operation, and cruise control. These include, but are not limited to, magnetoelectric speed sensors, Hall effect speed sensors, and photoelectric speed sensors.

[0048] S120. Determine the target vehicle's location within each preset light speed response zone of the current vehicle based on its position, thus obtaining the target light speed response zone.

[0049] Specifically, the preset headlight speed response zone is a pre-set headlight speed response zone for the high beams in the current vehicle. The high beams have different brightness gradation speeds within different headlight speed response zones. Users can adjust and set this headlight speed response zone according to actual usage needs; this embodiment does not specifically limit this. For example, the preset headlight speed response zone may include a slow response zone, a medium response zone, and a fast response zone. The target headlight speed response zone is the headlight speed response zone of the high beams in the current vehicle to which the target vehicle belongs.

[0050] In practice, after acquiring the location of the target vehicle using a camera, the adaptive high beam controller obtains the pre-set preset high beam response zones. Then, based on the target vehicle's location, it determines the target high beam response zone to which the target vehicle belongs, i.e., the high beam response zone to which the target vehicle belongs among the various preset high beam response zones of the current vehicle. For example, based on the target vehicle's location, it determines the target vehicle's orientation information relative to the current vehicle. Then, based on the orientation information, it determines whether the target vehicle is in the preset high beam response zone of the left high beam or the preset high beam response zone of the current vehicle. Finally, it determines the high beam response zone to which the target vehicle belongs among the various preset high beam response zones of the current vehicle, i.e., the target high beam response zone.

[0051] S130. Determine the duration of the brightness transition of the high beam of the current vehicle based on the target light speed response zone, the speed of the current vehicle, and the speed of the target vehicle.

[0052] Specifically, the brightness gradient duration is the time required for the high beams in the current vehicle to be turned off (brightness value adjusted from 100% to 0%) or turned on (brightness value adjusted from 0% to 100%).

[0053] Optionally, in one possible implementation, such as Figure 3 The image shown is an example diagram of the high beam switching process provided in this application. Figure 3 The LED beads in the diagram are the high beam beads used in current vehicles. The color intensity of the LED beads in the diagram indicates their brightness value (the lighter the color, the brighter the bead): 100% indicates that the brightness value of the LED bead is 100%, meaning that the high beam is on at this time; 100% - ΔT fd This indicates that the brightness value of the LED chip decreased by ΔT. fd 100% - 2ΔT fd This indicates that the brightness value of the LED chip decreased by 2ΔT. fd 0% indicates that the high beams are in a transitional off state; 0% indicates that the brightness of the LED beads is 0%, indicating that the high beams have changed from the on state to the off state.

[0054] Alternatively, in another possible implementation, such as Figure 4 The image shown is an example diagram of the high beam activation process provided in this application. Figure 4 The LED beads in the diagram are the high beam beads used in current vehicles. The color intensity of the LED beads in the diagram indicates their brightness value (the lighter the color, the greater the brightness value): 0% indicates that the brightness value of the LED bead is 0%, meaning that the high beam is off; 0% + ΔT lt This indicates that the brightness value of the LED bulb increased by ΔT. lt 0% + 2ΔT lt This indicates that the brightness value of the LED bulb increased by 2ΔT. lt 100% indicates that the high beams are in a transitional on / off state; 100% indicates that the brightness of the LED bulbs is 100%, meaning that the high beams have switched from off to on.

[0055] In practice, after determining the target light speed response zone to which the target vehicle belongs, the adaptive high beam controller determines the brightness transition duration of the high beams in the current vehicle to be turned off (brightness value adjusted from 100% to 0%) or turned on (brightness value adjusted from 0% to 100%) based on the target light speed response zone, the current vehicle's speed, and the target vehicle's moving speed relative to the current vehicle.

[0056] S140. Determine the brightness adjustment amount for each brightness update cycle based on the current brightness gradient duration and brightness update cycle of the vehicle's high beams.

[0057] Specifically, the brightness update cycle is the time required for a pre-set CAN message to update the high beam LED brightness setting once. It represents the time needed to adjust the high beam brightness once. Users can adjust and set this brightness update cycle according to actual usage needs; this embodiment does not impose a specific limitation. For example, the brightness update cycle can be 5 seconds. The brightness adjustment amount is the increase or decrease in brightness value required by the high beam within each brightness update cycle.

[0058] In practice, after determining the brightness gradient duration of the current vehicle's high beams, the adaptive high beam controller obtains the pre-set brightness update cycle of the high beams. Then, based on the brightness gradient duration and the brightness update cycle, it determines the amount of brightness adjustment that the high beams need to make in each brightness update cycle, so as to adjust the brightness value of the high beams from 100% to 0% or from 0% to 100% within the specified brightness gradient duration.

[0059] For example, when the high beam needs to be switched from on to off, the adaptive high beam controller determines the amount of brightness adjustment that needs to be reduced in each brightness update cycle; when the high beam needs to be switched from off to on, the adaptive high beam controller determines the amount of brightness adjustment that needs to be increased in each brightness update cycle.

[0060] S150. Adjust the brightness of the high beams according to the brightness adjustment amount of each brightness update cycle.

[0061] In practice, after determining the required brightness adjustment amount for the high beams in the current vehicle within each brightness update cycle, the adaptive high beam controller sends control commands to the left and right high beams via the CAN bus based on the brightness adjustment amount. This adjusts the brightness of the left and right high beams within each brightness update cycle, allowing the high beams to smoothly turn off or on during the corresponding brightness transition duration. The control commands can be to increase or decrease the brightness by 20%.

[0062] For example, when the high beam needs to be switched from on to off and the brightness adjustment is 20%, the adaptive high beam controller controls the brightness values ​​of the left and right high beams to decrease by 20% in each brightness update cycle; when the high beam needs to be switched from off to on, the adaptive high beam controller controls the brightness values ​​of the left and right high beams to increase by 20% in each brightness update cycle.

[0063] The technical solution of this application embodiment is applied to the current vehicle, obtaining the speed of the current vehicle and the speed and position of the target vehicle; determining the target vehicle's light speed response zone in each preset light speed response zone of the current vehicle based on the target vehicle's position, thus obtaining the target light speed response zone; determining the brightness gradient duration of the current vehicle's high beams based on the target light speed response zone, the current vehicle's speed, and the target vehicle's speed; determining the brightness adjustment amount for each brightness update cycle based on the brightness gradient duration and brightness update cycle of the current vehicle's high beams; and adjusting the brightness of the high beams according to the brightness adjustment amount for each brightness update cycle. In the above technical solution, the target vehicle's position relative to the current vehicle is first used to determine the target light speed response zone. Then, based on the target light speed response zone, the target vehicle's speed relative to the current vehicle, and the current vehicle's speed, the duration of the high beam brightness transition (e.g., the duration of gradual brightening or fading) is determined. Based on the high beam brightness transition duration and a pre-set brightness update cycle, the required brightness adjustment amount for the high beam in each update cycle is determined. Finally, the high beam brightness is controlled based on the determined brightness adjustment amount, such as increasing or decreasing the high beam brightness. This achieves an anti-glare function and provides a smooth light transition effect, reducing the abruptness and flicker of light changes, lowering the risk of traffic accidents caused by drastic brightness changes, and solving the problems of abrupt light changes, strong flickering, and safety hazards associated with light changes, thereby improving the user's driving experience at night. Simultaneously, the target vehicle's target light speed response zone is determined based on its position relative to the current vehicle. Then, the duration of the high beam brightness transition for the current vehicle is determined based on the target vehicle's target light speed response zone, its speed relative to the current vehicle, and the current vehicle's speed. This allows for real-time dynamic adjustment of the high beam's brightness transition duration based on the target vehicle's position, ensuring a fast high beam on / off response and reducing the risk of traffic accidents caused by untimely light switching. This application dynamically adjusts the high beam brightness transition duration of the current vehicle based on the current vehicle's speed, the target vehicle's position, and its speed, ensuring a fast high beam on / off response while providing a smooth light transition effect. This achieves anti-glare functionality, reduces the abruptness and flicker of light changes, and solves the problems of abrupt light changes, strong flashing, and potential safety hazards, thereby improving the driving experience for users at night.

[0064] The following further describes a high beam control method provided by an embodiment of this application. Figure 5 This is another schematic flowchart of a high beam control method provided in this application. The embodiments of this application are specific modifications based on the above embodiments.

[0065] See Figure 5The method in this embodiment includes, but is not limited to, the following steps:

[0066] S210. Obtain the current vehicle's speed and the target vehicle's speed and position.

[0067] S211. Determine whether the target vehicle has entered or left the current vehicle's lighting control area based on the target vehicle's location.

[0068] The lighting control area is a merged area of ​​the various preset light speed response zones of the current vehicle.

[0069] Specifically, the lighting control area is the area illuminated by the high beams of the current vehicle, which is the merged area of ​​various preset light speed response zones. Optionally, in one possible implementation, such as Figure 6 The diagram shown is an example of the headlight speed response zone division provided in this application. The preset headlight speed response zone can be divided into three zones based on the current illumination angle of the vehicle's high beam: a slow response zone, a medium response zone, and a fast response zone. The left and right high beams each contain one of the three headlight speed response zones.

[0070] For example, based on the illumination angle of the left high beam, three preset light speed response zones are defined: when the illumination angle is within [-15°, -7°), the preset light speed response zone is a fast response zone; when the illumination angle is within [-7°, 0°), the preset light speed response zone is a medium response zone; and when the illumination angle is within [0°, 15°], the preset light speed response zone is a slow response zone. Similarly, based on the illumination angle of the right high beam, three preset light speed response zones are defined: when the illumination angle is within [-15°, 0°), the preset light speed response zone is a slow response zone; when the illumination angle is within [0°, 7°), the preset light speed response zone is a medium response zone; and when the illumination angle is within [7°, 15°], the preset light speed response zone is a fast response zone.

[0071] In its implementation, after obtaining the position of the target vehicle relative to the current vehicle, the adaptive high beam controller determines whether the target vehicle has entered or left the current vehicle's lighting control area based on its position. If the target vehicle enters or leaves the current vehicle's lighting control area, it indicates that the target vehicle entered the current vehicle's lighting control area from a distance (not located within the current vehicle's lighting control area), or the target vehicle left the current vehicle's lighting control area from within it. In this case, the current vehicle needs to change the on / off state of its high beams, and step S212 is executed. If the target vehicle does not enter or leave the current vehicle's lighting control area, it indicates that the target vehicle has never appeared within the current vehicle's lighting control area, i.e., it has neither entered nor left the area. In this case, the current vehicle does not need to change the on / off state of its high beams, and step S221 is executed.

[0072] S212. If the target vehicle enters or leaves the lighting control area, the target angle of the target vehicle relative to the current vehicle is determined based on the position of the target vehicle.

[0073] Specifically, the target angle is the angle between the position of the target vehicle and the current vehicle.

[0074] In practice, when the target vehicle enters or leaves the current vehicle's lighting control area based on its position, the current vehicle needs to change the on / off state of its high beams. Specifically, if the target vehicle enters the current vehicle's lighting control area, the adaptive high beam controller changes the high beams from on to off; if the target vehicle leaves the current vehicle's lighting control area, the adaptive high beam controller changes the high beams from off to on. At this time, the adaptive high beam controller determines the target angle of the target vehicle relative to the current vehicle based on its position.

[0075] For example, when the target angle is within [-15°, 15°], the target vehicle enters the current vehicle's lighting control area; when the target angle changes from being within [-15°, 15°] to not being within [-15°, 15°], the target vehicle leaves the current vehicle's lighting control area.

[0076] S213. Determine the target vehicle's light speed response zone in each preset light speed response zone of the current vehicle based on the target angle, and obtain the target light speed response zone.

[0077] In practice, after determining the target angle of the target vehicle, the adaptive high beam controller determines the target light speed response zone to which the target vehicle belongs based on the target angle, that is, the light speed response zone to which the target vehicle's position belongs in the current vehicle's light control area.

[0078] For example, the target vehicle's target headlight speed response zone is determined based on the target angle: when the target angle is within [-15°, -7°) of the left high beam, the target vehicle's target headlight speed response zone is the fast response zone of the left high beam; when the target angle is within [-7°, 0°) of the left high beam, the target vehicle's target headlight speed response zone is the medium response zone of the left high beam; when the target angle is within [0°, 15°] of the left high beam, the target vehicle's target headlight speed response zone is the medium response zone of the left high beam; when the target angle is within [0°, 15°] of the left high beam, the target headlight speed response zone is the medium response zone of the left high beam. The target vehicle's target headlight speed response zone should be designated as the slow response zone for the left high beam. When the target angle is within the range of [-15°, 0°] of the right high beam, the target headlight speed response zone for the target vehicle should be the slow response zone for the right high beam. When the target angle is within the range of [0°, 7°] of the right high beam, the target headlight speed response zone for the target vehicle should be the medium response zone for the right high beam. When the target angle is within the range of [7°, 15°] of the right high beam, the target headlight speed response zone for the target vehicle should be the fast response zone for the right high beam.

[0079] S214. Obtain the basic gradient duration corresponding to the target light speed response zone.

[0080] Specifically, the base gradient duration is a preset gradient duration. Different light speed response zones correspond to different base gradient durations. Users can adjust and set this base gradient duration according to actual usage needs. This embodiment does not impose specific limitations on this. Optionally, the base gradient duration of the slow response zone is longer than that of the medium response zone, and the base gradient duration of the medium response zone is longer than that of the fast response zone.

[0081] In practice, after determining the target light speed response zone to which the target vehicle belongs, the adaptive high beam controller obtains the pre-set basic transition duration corresponding to that target light speed response zone. For example, when the target light speed response zone is a slow response zone, the basic transition duration is 500 milliseconds; when the target light speed response zone is a medium response zone, the basic transition duration is 300 milliseconds; and when the target light speed response zone is a fast response zone, the basic transition duration is 200 milliseconds.

[0082] S215. Determine the first gradual change in the duration of the high beam based on the speed of the target vehicle.

[0083] Furthermore, the first gradual change in the high beam duration is determined based on the target vehicle's speed and the preset first proportional coefficient corresponding to the target light speed response zone.

[0084] Specifically, the preset first proportional coefficient is a pre-set proportional coefficient. Different light speed response zones correspond to different preset first proportional coefficients. Users can adjust and set the preset first proportional coefficient according to actual usage needs. This embodiment does not specifically limit this. For example, when the target light speed response zone is a slow response zone, the preset first proportional coefficient is 0.5; when the target light speed response zone is a medium response zone, the preset first proportional coefficient is 0.7; and when the target light speed response zone is a fast response zone, the preset first proportional coefficient is 0.8.

[0085] In specific implementation, after determining the target light speed response zone to which the target vehicle belongs based on the target vehicle's target angle, the adaptive high beam controller obtains a preset first proportional coefficient corresponding to the pre-set target light speed response zone, and then determines the first gradual change in the high beam duration of the current vehicle based on the target vehicle's speed and the preset first proportional coefficient. Optionally, the first gradual change in duration can be divided into the first gradual change in duration for turning off the high beam and the first gradual change in duration for turning on the high beam.

[0086] Optionally, the first gradual change in the high beam duration is determined based on the target vehicle's speed and a preset first proportional coefficient corresponding to the target light speed response zone, including:

[0087] ΔT fd_Tv =-K Tv *v T

[0088] ΔT lt_Tv =-K Tv *v T

[0089] Where, ΔT fd_Tv ΔT is the amount of change in the first gradual transition time when the high beams are turned off. lt_Tv K represents the initial gradual change in the duration of activating high beams. Tv v is the first preset proportional coefficient corresponding to the target light speed response zone. T The speed of the target vehicle.

[0090] S216. Determine the second gradual change in the duration of the high beam based on the current speed of the vehicle.

[0091] Furthermore, the second gradual change in the high beam duration is determined based on the current vehicle speed and the preset second proportional coefficient corresponding to the target light speed response zone.

[0092] Specifically, the preset second proportional coefficient is a pre-set proportional coefficient. Different preset second proportional coefficients correspond to different light speed response zones. Users can adjust and set the preset second proportional coefficient according to actual usage needs. This embodiment does not specifically limit this. For example, when the target light speed response zone is a slow response zone, the preset second proportional coefficient is 0.05; when the target light speed response zone is a medium response zone, the preset second proportional coefficient is 0.07; and when the target light speed response zone is a fast response zone, the preset second proportional coefficient is 0.1.

[0093] In specific implementation, after determining the target light speed response zone to which the target vehicle belongs based on the target vehicle's target angle, the adaptive high beam controller obtains a preset second proportional coefficient corresponding to the pre-set target light speed response zone, and then determines the second gradual change amount of the high beam duration for the current vehicle based on the current vehicle's speed and the preset second proportional coefficient. Optionally, the second gradual change amount can be divided into the second gradual change amount for turning off the high beam and the second gradual change amount for turning on the high beam.

[0094] Optionally, the second gradual change in the high beam duration is determined based on the current vehicle speed and the preset second proportional coefficient corresponding to the target light speed response zone, including:

[0095] ΔT fd_v =-K v *v

[0096] ΔT lt_v =-K v *v

[0097] Where, ΔT fd_v ΔT is the second gradual change in the duration of turning off the high beams. lt_v K is the second gradual change in the duration of activating high beams. v The second preset proportional coefficient is the target light speed response zone, and v is the current vehicle speed.

[0098] S217. Determine the brightness gradient duration of the high beam based on the basic gradient duration, the change in the first gradient duration, and the change in the second gradient duration.

[0099] Optionally, the brightness gradient duration can be divided into a brightness gradient duration when the high beams are off and a brightness gradient duration when the high beams are on, with the brightness gradient duration when the high beams are off being shorter than the brightness gradient duration when the high beams are on.

[0100] In practice, the adaptive high beam controller determines the brightness gradient duration required to turn the high beams on or off in the current vehicle based on the base gradient duration corresponding to the target light speed response zone to which the target vehicle belongs, the first gradient duration change, and the second gradient duration change of the current vehicle. In other words, the adaptive high beam controller calculates the sum of the base gradient duration, the first gradient duration change, and the second gradient duration change.

[0101] T fd =T fd_0 +ΔT fd_Tv +ΔT fd_v

[0102] T lt =T lt_0 +ΔT lt_Tv +ΔT lt_v

[0103] Among them, T fd To control the duration of the brightness transition when turning off high beams, T lt To adjust the brightness of the high beams over a gradual manner, T fd_0 The basic gradual transition duration for turning off high beams, T lt_0 The basic gradual duration for turning on high beams.

[0104] S218. Determine the number of times the high beam brightness is updated based on the current brightness gradient duration and brightness update cycle of the vehicle's high beam.

[0105] Specifically, the brightness update count is the number of adjustments required to adjust the brightness of the high beams so that the high beams are either turned off (brightness adjusted from 100% to 0%) or turned on (brightness adjusted from 0% to 100%) within the brightness gradient duration.

[0106] In practice, after determining the brightness transition duration of the high beams in the current vehicle, the adaptive high beam controller obtains the pre-set brightness update cycle of the high beams. Then, based on the brightness transition duration and the brightness update cycle, it determines the number of brightness updates for the high beams. That is, the number of brightness updates (denoted as n) is the ratio of the brightness transition duration to the brightness update cycle.

[0107]

[0108]

[0109] Where, n fd The number of brightness updates required to turn off high beams, n lt The number of brightness updates required to turn on the high beams, where τ is the brightness update cycle.

[0110] S219. Determine the brightness adjustment amount for each brightness update cycle based on the number of brightness updates and the preset total brightness value.

[0111] Specifically, the preset total brightness value is the pre-set total brightness value of the high beams. Users can adjust and set this preset total brightness value according to their actual usage needs; this embodiment does not impose specific limitations on it. For example, the preset total brightness value can be 100%.

[0112] In practice, after determining the number of brightness updates for the high beams in the current vehicle, the adaptive high beam controller obtains the preset total brightness value of the high beams. Then, based on the number of brightness updates and the preset total brightness value, it determines the amount of brightness adjustment required for the high beams in each brightness update cycle. That is, the brightness adjustment amount (ΔT) is the ratio of the preset total brightness value to the number of brightness updates.

[0113]

[0114]

[0115] Where, ΔT fd ΔT is the amount of brightness adjustment required to turn off the high beams in each brightness update cycle. lt The amount of brightness adjustment required to turn on the high beams in each brightness update cycle, where N is the preset total brightness value.

[0116] S220. Adjust the brightness of the high beams according to the brightness adjustment amount of each brightness update cycle.

[0117] For example, when a target vehicle enters the current vehicle's lighting control area and the brightness adjustment is 25%, the adaptive high beam controller controls the brightness values ​​of the left and right high beams to decrease by 25% in each brightness update cycle; when the target vehicle leaves the current vehicle's lighting control area and the brightness adjustment is 25%, the adaptive high beam controller controls the brightness values ​​of the left and right high beams to increase by 25% in each brightness update cycle.

[0118] S221. If the target vehicle does not enter or leave the lighting control area, the current vehicle will not operate the high beams.

[0119] In practice, when the target vehicle does not enter or leave the current vehicle's lighting control area, it means that the target vehicle has never appeared in the current vehicle's lighting control area, i.e., it has not entered or left the area. The current vehicle does not need to change the on / off state of the high beams. At this time, the current vehicle's adaptive high beam controller does not perform any operation on the high beams.

[0120] The technical solution provided in this embodiment involves an adaptive high beam controller determining whether a target vehicle has entered or left the current vehicle's lighting control area based on the target vehicle's position relative to the current vehicle. When the target vehicle enters or leaves the current vehicle's lighting control area, the target angle of the target vehicle is determined based on its position. Then, the target light speed response zone to which the target vehicle belongs is determined based on the target angle. Next, based on the target light speed response zone of the target vehicle, the speed of the target vehicle, and the speed of the current vehicle, the basic gradient duration, the first gradient duration change, and the second gradient duration change of the high beam in the current vehicle are determined. This determines the brightness gradient duration of the high beam. Finally, the brightness update frequency of the high beam is determined based on the brightness gradient duration, the brightness update cycle, and the preset total brightness value. The system calculates the brightness adjustment amount within each brightness update cycle and adjusts the brightness of the left and right high beams of the current vehicle via the CAN bus according to the brightness adjustment amount. This allows the high beams to be switched on or off within the brightness transition time, achieving an anti-glare function and smooth switching of the high beams on or off. It also ensures a fast response time for the high beams, reducing the risk of traffic accidents caused by drastic brightness changes and improving the user's nighttime driving experience. When the target vehicle does not enter or leave the current vehicle's lighting control area, no operation of the high beams is required, reducing the complexity of implementing the light transition effect and achieving a smoother light transition effect. This reduces additional operations and ensures that the lights provide good illumination for the user. Furthermore, different light speed response zones are defined based on the current vehicle's high beam illumination angle, allowing different reference transition times within each zone. The system also adjusts the brightness transition time of the high beams in real time based on the target vehicle's real-time relative position, further reducing the risk of traffic accidents caused by untimely light switching.

If the target vehicle enters or leaves the lighting control area, the module is triggered to determine the lighting speed response zone to which the target vehicle belongs in the current vehicle's various preset lighting speed response zones based on the target vehicle's position.

[0144] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the above-described division of functional modules is merely an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above. The specific working process of the functional modules described above can be referred to the corresponding process in the foregoing method embodiments, and will not be repeated here.

[0145] The device of this application is applied to a current vehicle to acquire the speed of the current vehicle and the speed and position of a target vehicle; it determines the target vehicle's position within each preset headlight speed response zone of the current vehicle based on the target vehicle's position, thus obtaining the target headlight speed response zone; it determines the brightness gradient duration of the current vehicle's high beams based on the target headlight speed response zone, the current vehicle's speed, and the target vehicle's speed; it determines the brightness adjustment amount for each brightness update cycle based on the brightness gradient duration and brightness update cycle of the current vehicle's high beams; and it adjusts the brightness of the high beams according to the brightness adjustment amount for each brightness update cycle. In the above technical solution, the target vehicle's position relative to the current vehicle is first used to determine the target light speed response zone. Then, based on the target light speed response zone, the target vehicle's speed relative to the current vehicle, and the current vehicle's speed, the duration of the high beam brightness transition (e.g., the duration of gradual brightening or fading) is determined. Based on the high beam brightness transition duration and a pre-set brightness update cycle, the required brightness adjustment amount for the high beam in each update cycle is determined. Finally, the high beam brightness is controlled based on the determined brightness adjustment amount, such as increasing or decreasing the high beam brightness. This achieves an anti-glare function and provides a smooth light transition effect, reducing the abruptness and flicker of light changes, lowering the risk of traffic accidents caused by drastic brightness changes, and solving the problems of abrupt light changes, strong flickering, and safety hazards associated with light changes, thereby improving the user's driving experience at night. Simultaneously, the target vehicle's target light speed response zone is determined based on its position relative to the current vehicle. Then, the duration of the high beam brightness transition for the current vehicle is determined based on the target vehicle's target light speed response zone, its speed relative to the current vehicle, and the current vehicle's speed. This allows for real-time dynamic adjustment of the high beam's brightness transition duration based on the target vehicle's position, ensuring a fast high beam on / off response and reducing the risk of traffic accidents caused by untimely light switching. This application dynamically adjusts the high beam brightness transition duration of the current vehicle based on the current vehicle's speed, the target vehicle's position, and its speed, ensuring a fast high beam on / off response while providing a smooth light transition effect. This achieves anti-glare functionality, reduces the abruptness and flicker of light changes, and solves the problems of abrupt light changes, strong flashing, and potential safety hazards, thereby improving the driving experience for users at night.
