Description

Technical Field

[0001] This disclosure relates to a system and method for controlling the headlights of a vehicle, and more specifically to a system for controlling the headlights of a vehicle and a method for controlling the shadow area of ​​the headlights. Background Technology

[0002] Typically, a vehicle includes lights that serve two purposes: illumination for easily identifying objects positioned around the vehicle while driving at night, and signaling to other vehicles or road users to indicate the vehicle's status. For example, headlights, taillights, and fog lights are used for illumination, while turn signals, taillights, and brake lights are used for signaling.

[0003] When driving at night or in tunnels with low light intensity, drivers can safely navigate by identifying the areas in front of and behind the vehicle using light emitted from the light source used in the vehicle's headlights or taillights. In this case, the vehicle's lights include optical elements and multiple reflective surfaces to properly disperse, polarize, or focus the light emitted from the light source to change the direction of travel of the refracted light forward.

[0004] Recently, the demand for safe driving has been increasing. For example, when a vehicle is driving at night with its headlights on, drivers of oncoming or preceding vehicles may experience glare, increasing the likelihood of an accident. Ideally, this would ensure the driver's own visibility while minimizing obstruction of the visibility of drivers of oncoming or preceding vehicles.

[0005] It should be understood that the above-described matters in the related art are merely for the purpose of facilitating an understanding of the background of this disclosure and should not be considered as prior art known to those skilled in the art. Summary of the Invention

[0006] Therefore, this disclosure provides a system and method for controlling the headlights of a vehicle, which prevents glare to the driver of the vehicle in front by forming a shadow area relative to the vehicle in front and by correcting the position of the shadow area relative to the vehicle in front to form a shadow area at a precise position.

[0007] According to one aspect of this disclosure, a system for controlling headlights of a vehicle may be provided. The system includes: a lamp unit comprising a plurality of light sources and configured to form a shadow area in a light-emitting region by adjusting the position to which light is emitted and the light intensity of each light source; an information collector configured to acquire an image of the front side based on a driving direction; and a controller configured to receive information acquired by the information collector regarding a vehicle ahead and information regarding the shadow area formed by the lamp unit, and to control the lamp unit to perform shadow area aiming correction to position the vehicle ahead at the center side of the shadow area when the vehicle ahead is not positioned at the center side of the shadow area.

[0008] The information collector can check whether each of the left and right sides of the headlights or taillights of the vehicle in front is on, and if at least one of the left and right sides of the headlights or taillights of the vehicle in front is not on, the controller may not perform aiming correction of the shadow area based on the shadow area and the position of the vehicle in front.

[0009] When the communication device determines that the road in the direction of travel is a straight road with a predetermined distance or greater, the controller can perform aiming correction of the shadow area based on the shadow area and the position of the vehicle in front.

[0010] The system may also include a driving status information unit configured to identify the driving status of the vehicle. The controller can receive information about the steering wheel angle and the vehicle height from the driving status information unit and can perform aiming correction of the shadow area based on the position of the shadow area and the vehicle in front when it is determined that the vehicle is driving in a straight line and on a flat road.

[0011] The information collector can acquire images of the front side based on the driving direction and classify the vehicles in front as leading vehicles or oncoming vehicles. When it receives information indicating that both leading vehicles and oncoming vehicles are present, the controller can perform aiming correction of the shadow area based on the position of the shadow area and the vehicle in front by prioritizing the leading vehicles.

[0012] The information collector can identify the opposite ends of the vehicle ahead and the opposite ends of the shadow area, and the controller can determine whether the distance between the opposite ends of the shadow area and the distance between the opposite ends of the vehicle ahead match each other.

[0013] The controller can compare the side distance between one end of the shadow area and one end of the vehicle in front, and the remaining side distance between the remaining end of the shadow area and the remaining end of the vehicle in front, and can control the light unit to make the side distance and the remaining side distance the same when they are different from each other.

[0014] The controller can check whether the vehicle in front is located on the center side of the shadow zone, and can perform aiming correction of the shadow zone when the distance to the vehicle in front is determined by the information collector to be equal to or greater than the pre-stored set distance.

[0015] On the other hand, a method for controlling the headlights of a vehicle includes: emitting light to form a shadow area relative to a vehicle in front in a light emitting area; acquiring an image of the front side based on the direction of travel, collecting information about the vehicle in front, and checking the shadow area; determining whether the vehicle in front is located on the center side of the shadow area within the shadow area; and when the vehicle in front is not located on the center side of the shadow area within the shadow area, correcting the position of the shadow area to position the vehicle in front on the center side of the shadow area.

[0016] The method may further include determining whether the vehicle is traveling in a straight line and identifying the vehicle's driving state based on information about the steering wheel angle and information about the vehicle's height to determine whether the vehicle is traveling on a flat road. Determining whether the vehicle ahead is located on the center side of the shaded area may include determining whether the vehicle ahead is located on the center side of the shaded area when it is determined that the vehicle is traveling in a straight line and on a flat road.

[0017] Acquiring an image may include classifying and identifying a vehicle ahead as a preceding vehicle or an oncoming vehicle, and determining whether a vehicle ahead is located in the center of a shadow area may include checking whether a vehicle ahead is located in the center of a shadow area by prioritizing the preceding vehicle when information indicating that both preceding and oncoming vehicles are present.

[0018] Acquiring an image may include identifying the opposite ends of a vehicle ahead and the opposite ends of a shadow area, and determining whether a vehicle ahead is located on the center side of a shadow area may include determining whether the distance between the opposite ends of the shadow area and the distance between the opposite ends of the vehicle ahead match each other.

[0019] Determining whether the vehicle ahead is located in the center of the shadow area may include comparing the lateral distance between one end of the shadow area and one end of the vehicle ahead, and the lateral distance between the remaining end of the shadow area and the remaining end of the vehicle ahead, and the position correction may include adjusting the position of the shadow area to make the lateral distance and the remaining lateral distance the same when the lateral distance and the remaining lateral distance are different from each other.

[0022] Figure 4 and Figure 5 This is a flowchart of a method for controlling a vehicle's headlights. Detailed Implementation

[0023] Reference will now be made in detail to systems and methods for controlling vehicle headlights according to exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings.

[0024] Figure 1 This is a diagram illustrating the configuration of a system for controlling vehicle headlights in some forms of this disclosure. Figure 2 and Figure 3 It is used for explanation Figure 1 The diagram shown is of a system used to control the headlights of a vehicle. Figure 4 and Figure 5 This is a flowchart of a method for controlling a vehicle's headlights.

[0025] like Figure 1 As shown, a system for controlling a vehicle's headlights according to this disclosure may include: a lamp unit 100, which includes a plurality of light sources and is configured to form a shadow area in a light emission region by adjusting the position of light emission and the light intensity of each light source; an information collector 200, configured to acquire an image of the front side based on the driving direction; and a controller 300, configured to receive information about the vehicle ahead and information about the shadow area formed by the lamp unit 100 acquired by the information collector 200, and to control the lamp unit 100 to perform shadow area aiming correction to position the vehicle ahead on the center side of the shadow area when the vehicle ahead is not located on the center side of the shadow area.

[0026] Here, the lamp unit 100 may include an adaptive driven beam (ADB) headlamp, and a shadow area may be formed in the light emission region by adjusting the position to which light is emitted from each light source or the amount of light emitted from each light source. That is, the lamp unit 100 may achieve the shadow area by a rotation method that drives a rotary actuator or by a matrix method that turns the light sources on or off.

[0027] The information collector 200 may include a camera sensor to acquire images of the front side based on the direction of travel and to identify the position of light based on the acquired images. That is, the information collector 200 can acquire images of the front side based on the direction of travel to identify vehicles ahead based on the position of light from the taillights of preceding vehicles or the headlights of oncoming vehicles. The information collector 200 can also identify shadow areas formed by the lamp unit 100 based on brightness, contrast, color temperature, sharpness, etc.

[0028] The controller 300 can receive information about the vehicle ahead and information about the shadow area formed by the lamp unit 100, acquired by the information collector 200. Here, the controller 300 can check whether the vehicle ahead is located on the center side of the shadow area, and can determine that the shadow area formed by the lamp unit 100 is not properly aimed if the vehicle ahead is not located on the center side of the shadow area. Therefore, the controller 300 can control the lamp unit 100 to perform shadow area aiming correction to position the vehicle ahead on the center side of the shadow area, thereby forming a shadow area at a precise position within the vehicle ahead.

[0029] Therefore, the controller 300 can accurately locate the shadow area formed by the lamp unit 100 in the vehicle in front, thereby improving the accuracy of the shadow area formation and preventing the driver of the vehicle in front from being glared.

[0030] The information collector 200 can check whether each of the left and right sides of the headlights or taillights of the vehicle in front is turned on, and if at least one of the left and right sides of the headlights or taillights of the vehicle in front is not turned on, the controller 300 may not perform aiming correction of the shadow area based on the position of the shadow area and the position of the vehicle in front.

[0031] In this way, the information collector 200 can check whether the left and right sides of the headlights or taillights of the vehicle ahead are on, thereby determining whether the camera sensor is operating normally and accurately identifying the vehicle ahead. That is, as... Figure 2 As shown, when the information collector 200 determines that at least one of the left and right sides of the headlights or taillights of the vehicle ahead is not turned on, the controller 300 may determine that the camera sensor is malfunctioning or there is no vehicle ahead, and may not perform aiming correction of the shadow area based on the shadow area and the position of the vehicle ahead.

[0032] Thus, when the information collector 200 determines that the left and right sides of the headlights or taillights of the vehicle ahead are turned on, the controller 300 can determine that the camera is not abnormal and can perform aiming correction of the shadow area on another vehicle ahead.

[0033] When the communication device determines that the road in the direction of travel is a straight road with a predetermined distance or greater, the controller 300 can perform shadow area aiming correction based on the shadow area and the position of the vehicle ahead. Here, the communication device can be a navigation device, and when the communication device receives information indicating that the road in the direction of travel is a straight road with a predetermined distance or greater, the controller 300 can perform shadow area aiming correction based on the shadow area and the position of the vehicle ahead. When the road is sloping or curved, the left and right sides of the headlights or taillights of the vehicle ahead may change, or positions different from the initial design of the corresponding vehicle may be detected as open sides, and therefore the position of the shadow area in the vehicle ahead may not be accurately determined. This leads to an error regarding the position of the shadow area during shadow area aiming correction, and therefore, when it is determined that the road in the direction of travel is a straight road with a predetermined distance or greater, the controller 300 can perform shadow area aiming correction based on the shadow area and the position of the vehicle ahead.

[0034] The system for controlling the headlights of a vehicle may also include a driving status information unit 400 for identifying the driving status of the vehicle, and the controller 300 may receive information from the driving status information unit 400 about the driving status of the vehicle depending on the steering wheel angle and the height of the vehicle, and when it is determined that the vehicle is driving in a straight line and whether the vehicle is driving on a flat road, the controller 300 may perform aiming correction of the shadow area based on the shadow area and the position of the vehicle in front.

[0035] In other words, the controller 300 can determine whether the vehicle is traveling in a straight line and whether it is traveling on a flat road based on information about the steering wheel angle and the vehicle's height. Here, when the vehicle is traveling in a straight line, since the steering angle changes by 0°, and when the vehicle is traveling on a road without a slope, since the vehicle's height does not change, the controller 300 can accurately correct the position of the vehicle in front, which forms the shadow area, by performing shadow area aiming correction based on the shadow area and the position of the vehicle in front. Furthermore, when the position of the headlights or taillights of the vehicle in front is maintained for a predetermined time or longer as detected by the information collector 200, the controller 300 can perform shadow area aiming correction based on the position of the shadow area and the position of the vehicle in front.

[0036] Thus, when the conditions for straight-line driving, driving on a flat road, and the position of the vehicle ahead are met, the controller 300 can accurately correct and set the position of the shadow area formed relative to the vehicle ahead by performing aiming correction of the shadow area of ​​the lamp unit 100.

[0037] The information collector 200 can acquire images of the front side based on the driving direction and classify the vehicles in front as leading vehicles or oncoming vehicles. When it receives information indicating that both leading vehicles and oncoming vehicles are present, the controller 300 can perform aiming correction of the shadow area by prioritizing leading vehicles that are taller than oncoming vehicles and based on the position of the shadow area and the position of the vehicles in front.

[0038] When the information collector 200 detects the simultaneous presence of a leading vehicle and an oncoming vehicle, the controller 300 can prioritize processing the leading vehicle and perform shadow area aiming correction based on the positions of the shadow area and the vehicle ahead. Compared to oncoming vehicles, the camera sensor has a superior ability to identify leading vehicles. That is, in the case of oncoming vehicles, the vehicle and the oncoming vehicle are close to each other, thus increasing the relative speed compared to the leading vehicle and potentially reducing the camera sensor's recognition capability. Therefore, when the information collector 200 detects the simultaneous presence of a leading vehicle and an oncoming vehicle, the controller 300 can prioritize processing the leading vehicle to perform shadow area aiming correction.

[0039] The aiming correction in the shadow area will be described in detail below.

[0040] The information collector 200 can identify the opposite ends of the vehicle ahead and the opposite ends of the shadow area, and the controller 300 can determine whether the distance between the opposite ends of the shadow area matches the distance between the opposite ends of the vehicle ahead.

[0041] In other words, the information collector 200 can identify the opposite end of a vehicle ahead by the left and right sides of the headlights or taillights of the vehicle ahead, and can identify the opposite end of the shadow area by brightness, contrast, color temperature, etc.

[0042] In this way, the controller 300 can compare the opposite end of the shadow area input through the information collector 200 with the opposite end of the vehicle in front, and can perform shadow area aiming correction by controlling the lamp unit 100 so that the opposite end of the shadow area and the opposite end of the vehicle in front are the same. Thus, the lamp unit 100 can perform shadow area aiming correction by making the opposite end of the shadow area and the opposite end of the vehicle in front the same, and therefore the shadow area can be formed at the precise position of the vehicle in front.

[0043] When the information collector 200 determines that the distance to the vehicle ahead is equal to or greater than a pre-stored set distance, the controller 300 can check whether the vehicle ahead is located on the center side of the shadow area within the shadow zone and can perform shadow zone aiming correction. According to this disclosure, when the vehicle is relatively far from the vehicle ahead, the formation of the shadow zone can be highly effective, while when the vehicle and the vehicle ahead are too close and the position of the vehicle ahead changes relatively significantly, the accuracy of shadow zone aiming correction may decrease. Therefore, when the information collector 200 identifies that the distance to the vehicle ahead is equal to or greater than a pre-stored set distance, the controller 300 can check whether the vehicle ahead is located on the center side of the shadow area within the shadow zone and can perform shadow zone aiming correction.

[0044] Specifically, the controller 300 can compare the distance C1 between one side of the shadow area A1 and the one side of the vehicle in front B1, and the distance C2 between the other side of the shadow area A2 and the other side of the vehicle in front B2. When the distance C1 and the distance C2 are different from each other, the controller can control the lamp unit 100 to make the distance C1 and the distance C2 the same.

[0045] For example, such as Figure 3 As shown, when the information collector 200 checks that the distance C1 on one side of the shadow area is 4m and the distance C2 on the other side is 2m, the controller 300 can control the lamp unit 100 to change the position of the shadow area to the other side. In other words, when the position of the shadow area is changed to the other side by up to 1m by aiming and correcting the shadow area of ​​the lamp unit 100, the distances C1 on one side and C2 on the other side can match each other, and can be 3m.

[0046] In this way, the controller 300 can identify the distance between the opposite ends of the shadow area and the distance between the opposite ends of the vehicle in front, and can control the lamp unit 100 by calculating to make these distances the same as each other, and thus can form a shadow area at a precise position relative to the vehicle in front by performing the aiming correction of the shadow area of ​​the lamp unit 100.

[0047] like Figure 4 and Figure 5 As shown, the method for controlling the headlights of a vehicle according to the present disclosure may include: emitting light to form a shadow area relative to a vehicle in front in the light emission area (S100); acquiring an image of the front side based on the driving direction, collecting information about the vehicle in front, and checking the shadow area (S200); determining whether the vehicle in front is located on the center side of the shadow area within the shadow area (S300); and when the vehicle in front is not located on the center side of the shadow area within the shadow area, correcting the position of the shadow area to position the vehicle in front on the center side of the shadow area (S400).

[0048] In other words, according to this disclosure, it is possible to identify whether the vehicle ahead is located on the center side of the shadow area, and when the vehicle ahead is not located on the center side of the shadow area, the position of the shadow area can be adjusted to position the vehicle ahead on the center side of the shadow area. Here, the position of the shadow area can be adjusted by a rotation method using a rotary actuator of the driving lamp unit 100 or by a matrix method of turning the light source on or off. Therefore, according to this disclosure, the position of the shadow area can be accurately formed relative to the vehicle ahead, thereby improving the accuracy of shadow area formation and preventing glare to the driver of the vehicle ahead.

[0049] The method may also include identifying the vehicle's driving state based on information about the steering wheel's angle and information about the vehicle's height to determine whether the vehicle is driving in a straight line and whether it is driving on a flat road (S500), and determining whether the vehicle ahead is located on the center side of the shaded area may include determining whether the vehicle ahead is located on the center side of the shaded area when it is determined that the vehicle is driving in a straight line and on a flat road (S300).

[0050] In other words, determining whether the vehicle is traveling in a straight line and on a flat road (S500) can include determining this based on information about the steering wheel angle and the vehicle's height. Determining whether the vehicle ahead is located on the center side of the shaded area (S300) can include determining whether the vehicle ahead is located on the center side of the shaded area when it is determined that the vehicle is traveling in a straight line and on a flat road. Determining whether the vehicle ahead is located on the center side of the shaded area (S300) can also include checking whether the headlights or taillights of the vehicle ahead remain in their predetermined position for a predetermined time or longer.

[0051] Thus, according to this disclosure, when the conditions for the vehicle to travel in a straight line, the conditions for the vehicle to travel on a flat road, and the conditions related to the position of the vehicle in front are all met, the vehicle in front is identified as being located on the center side of the shadow area by determining whether the vehicle in front is located on the center side of the shadow area (S300), and the position of the shadow area can be adjusted by correcting the position of the shadow area (S400) so that the vehicle in front is positioned on the center side of the shadow area.

[0052] Collecting information about vehicles ahead (S200) may include classifying the vehicles ahead and determining them as either preceding vehicles or oncoming vehicles. Determining whether a vehicle ahead is located at the center of a shadow area within a shadow zone (S300) may include, when receiving information indicating the presence of both preceding and oncoming vehicles, prioritizing the preceding vehicles to identify whether the vehicle ahead is located at the center of a shadow area within a shadow zone. In other words, when checking for the simultaneous presence of preceding and oncoming vehicles by collecting information about vehicles ahead (S200), determining whether a vehicle ahead is located at the center of a shadow area within a shadow zone can be performed by prioritizing preceding vehicles, whose recognition capability by the camera sensor is superior to that of oncoming vehicles (S300). Thus, by prioritizing preceding vehicles, whose recognition capability by the camera sensor is superior to that of oncoming vehicles, determining whether a vehicle ahead is located at the center of a shadow area within a shadow zone (S300) can be performed, and therefore the position of the vehicle ahead within the shadow zone can be accurately identified, thereby improving the accuracy of the location of the shadow area.

[0053] Collecting information about the vehicle ahead (S200) may include identifying the opposite end of the vehicle ahead and the opposite side of the shadow area, and determining whether the vehicle ahead is located on the center side of the shadow area within the shadow area (S300) may include determining whether the distance between the opposite ends of the shadow area and the distance between the opposite ends of the vehicle ahead match each other.

[0054] Specifically, determining whether the vehicle ahead is located on the center side of the shadow area (S300) may include comparing the distance between one side of the shadow area and one side of the vehicle ahead with the distance between the other side of the shadow area and the other side of the vehicle ahead, and correcting the position of the shadow area (S400) may include adjusting the position of the shadow area to make the distance between the one side and the other side the same when the one side distance and the other side distance are different from each other.

[0055] In other words, determining whether the vehicle ahead is located on the center side of the shadow area within the shadow area (S300) may include comparing the distance between opposite sides of the shadow area on one side with the distance between opposite sides of the vehicle ahead on the other side, and correcting the position of the shadow area (S400) may include correcting the position of the shadow area so that the distance between opposite sides of the shadow area on one side with the distance between opposite sides of the vehicle ahead on the other side are the same. Here, determining whether the vehicle ahead is located on the center side of the shadow area within the shadow area (S300) may include checking whether the vehicle ahead is located on the center side of the shadow area within the shadow area when it is determined that the distance to the vehicle ahead is equal to or greater than a pre-stored set distance.

[0056] Thus, according to this disclosure, the distance between opposite ends of the shadow area and the distance between opposite ends of the vehicle in front can be identified, and the position of forming the shadow area can be adjusted by calculations that make these distances the same, and thus the shadow area can be formed at a precise position relative to the vehicle in front.

[0057] In other words, the control method according to this disclosure may include forming a shadow area in the light emission area regarding a vehicle ahead (S10) and checking information about the vehicle ahead and the shadow area (S20). In this case, the operation of checking the lights of the vehicle ahead can be performed and determining whether the vehicle ahead is in a normal state, whether the vehicle is traveling on a flat road, and whether the vehicle is traveling on a straight road (S30), and when all of these conditions are met, the position of the vehicle ahead within the shadow area can be identified (S40).

[0058] Here, when the vehicle in front is not positioned in the center of the shadow area, the position of the shadow area can be adjusted and the vehicle in front can be positioned in the center of the shadow area (S41 and S50).

[0059] The system and method for controlling the headlights of a vehicle, as configured as described above, can prevent glare to the driver of the vehicle in front by forming a shadow area relative to the vehicle in front, and can form a shadow area at a precise location by correcting the position of the shadow area relative to the vehicle in front.

[0060] The system and method for controlling the headlights of a vehicle, as configured as described above, can prevent glare to the driver of the vehicle in front by forming a shadow area relative to the vehicle in front, and can form a shadow area at a precise location by correcting the position of the shadow area relative to the vehicle in front.

[0061] Although the preferred embodiments of this disclosure are disclosed for illustrative purposes, those skilled in the art will understand that various modifications, additions and substitutions are possible without departing from the scope and spirit of this disclosure as disclosed in the appended claims.
