[0038] Figure 1 is a block diagram illustrating a vehicle according to an embodiment of the present disclosure.
[0039] Reference Figure 1 , a vehicle 1000 according to an embodiment of the present disclosure may include a light 1100 , a light controlling device 1200 , and a sensor 1300 .
[0040] The lamp 1100 may include a headlamp of the vehicle 1000. For example, the lamp 1100 may include a digital mirror device (DMD) or an LED array.
[0041] Sensor 1300 can measure the distance between the vehicle and the target object. For example, sensor 1300 can measure the distance between sensor 1300 and the ground. In an embodiment, sensor 1300 may include a sensor capable of measuring distance. For example, sensor 1300 may include at least one of an infrared sensor, an ultrasonic sensor, a time-of-flight (ToF) sensor, a radar sensor, and a lidar sensor.
[0042] In an embodiment, the sensor 1300 may include an infrared sensor (IR sensor), and the infrared sensor may include an LED (light-emitting component) that generates infrared and a light sensor (light-receiving component) that detects infrared, and may measure the distance between the target object and the infrared sensor based on a voltage that changes according to the amount of infrared light incident on the light-receiving component after the infrared light irradiated from the light-emitting component is reflected by the target object.
[0043] The light controlling device 1200 may acquire or receive distance information between the sensor 1300 and the ground from the sensor 1300. For example, the sensor 1300 may measure the distance between the ground and the sensor 1300 and may transmit the measured distance information to the light controlling device 1200.
[0044] The light control device 1200 may acquire or receive information about the sensor 1300. For example, the information about the sensor 1300 may include position information of the sensor 1300 and reference illumination angle information about the illumination angle of the sensor 1300 when the vehicle 1000 is horizontal to the ground. In an embodiment, the light control device 1200 may acquire or receive information about the sensor 1300 in advance before driving the vehicle 1000, or may acquire or receive information about the sensor 1300 from another device inside or outside the vehicle 1000.
[0045] The light control device 1200 can calculate the inclination of the vehicle 1000 based on the information obtained about the sensor 1300 and the distance information between the sensor 1300 and the ground. The light control device 1200 can generate a control signal for controlling the light 1100 of the vehicle 1000 based on the calculated inclination of the vehicle 1000. For example, when the vehicle 1000 tilts, since the light 1100 irradiates light in a direction different from the previously set irradiation angle, the light control device 1200 can generate a control signal for controlling the light 1100 based on the inclination of the vehicle 1000 to correct the irradiation angle of the light 1100.
[0046] The vehicle 1000 according to the embodiment of the present disclosure may allow the lamp 1100 to normally irradiate light through the operation of the light controlling apparatus 1200 even when the vehicle 1000 is tilted.
[0047] Figure 2 is a diagram illustrating a vehicle according to another embodiment of the present disclosure.
[0048] Reference Figure 2 , a vehicle 2000 according to another embodiment of the present disclosure may include a light 2100 , a light controlling device 2200 , and a sensor 2300 .
[0049] The lamp 2100 may include a first lamp 2110 and a second lamp 2120. For example, the first lamp 2110 may be a right headlamp of the vehicle 2000, and the second lamp 2120 may be a left headlamp of the vehicle 2000. In an embodiment, the first lamp 2110 and the second lamp 2120 may be actually connected to the vehicle 2000. Figure 1 The same as lamp 1100.
[0050] The sensor 2300 may include a first sensor 2310 and a second sensor 2320. For example, the first sensor 2310 may be coupled or attached to the first light 2110 of the vehicle 2000, and the second sensor 2320 may be coupled or attached to the second light 2120 of the vehicle 2000.
[0051] The first sensor 2310 and the second sensor 2320 may measure the distance between the first sensor 2310 and the ground and the distance between the second sensor 2320 and the ground, respectively, and may transmit the measured distance information to the light controlling device 2200. In an embodiment, the first sensor 2310 and the second sensor 2320 may be actually connected to the light controlling device 2200. Figure 1 The same as sensor 1300.
[0052] The light controlling device 2200 may calculate a first slope of the vehicle 2000 based on information about the first sensor 2310 and distance information between the ground and the first sensor 2310 measured from the first sensor 2310. The light controlling device 2200 may generate a first control signal for controlling the first light 2110 based on the first slope of the vehicle 2000.
[0053] The light controlling device 2200 may calculate a second slope of the vehicle 2000 based on information about the second sensor 2320 and distance information between the ground and the second sensor 2320 measured from the second sensor 2320. The light controlling device 2200 may generate a second control signal for controlling the second light 2120 based on the second slope of the vehicle 2000.
[0054] The light controlling device 2200 may individually correct the illumination angles of the first and second lamps 2110 and 2120 by generating the first and second control signals with respect to each of the first and second lamps 2110 and 2120 .
[0055] In embodiments, the first sensor 2310 can illuminate light in a direction different from the illumination angle of the first lamp 2110. For example, if the illumination angles of the first sensor 2310 and the first lamp 2110 are the same, and if the vehicle 2000 tilts and the first lamp 2110 is raised, the first sensor 2310 is also raised, and thus may not be able to measure the distance to the ground. Therefore, the first sensor 2310 may need to be configured to illuminate light in a direction different from the illumination angle of the first lamp 2110. In embodiments, the second sensor 2320 can illuminate light in a direction different from the illumination angle of the second lamp 2120. For example, if the illumination angles of the second sensor 2320 and the second lamp 2120 are the same, and if the vehicle 2000 tilts and the second lamp 2120 is raised, the second sensor 2320 is also raised, and thus may not be able to measure the distance to the ground. Therefore, the second sensor 2320 may need to be configured to illuminate light in a direction different from the illumination angle of the second lamp 2120.
[0056] Figure 3 is a block diagram illustrating a light controlling apparatus according to an embodiment of the present disclosure.
[0057] Reference Figure 3 The light controlling device 100 according to an embodiment of the present disclosure may include an information acquirer 110 and a controller 120. In an embodiment, the light controlling device 100 may actually be connected to Figure 1 The light control device 1200 and Figure 2 The light control device 2200 is the same.
[0058] The information acquirer 110 may acquire information about a sensor of the vehicle. For example, the sensor information may include position information of the sensor and reference illumination angle information regarding an illumination angle of the sensor when the vehicle is horizontal to the ground. In this case, the sensor position information may include information regarding the height at which the sensor is installed from the ground.
[0059] The information acquirer 110 may acquire distance information between the sensor and the ground from the sensor. For example, the information acquirer 110 may acquire distance information between the sensor and the ground measured by the sensor from the sensor. Depending on the embodiment, the distance between the sensor and the ground may be a value that varies depending on the inclination of the vehicle.
[0060] The controller 120 may calculate the vehicle's inclination based on the information obtained from the information acquirer 110. For example, the controller 120 may calculate the vehicle's inclination based on information about the sensor and information about the distance between the sensor and the ground. The controller 120 may calculate the sensor's illumination angle based on the sensor's position information and information about the distance between the sensor and the ground. Furthermore, the controller 120 may calculate the vehicle's inclination by comparing reference illumination angle information with the calculated sensor illumination angle.
[0061] Figure 4 is a diagram illustrating how the light controlling apparatus according to an embodiment of the present disclosure calculates the inclination of a vehicle.
[0062] Reference Figure 4 When weight is applied or pressed to the rear side of vehicle 210, the inclination of vehicle 210 may change. Controller 120 may acquire position information 230 of sensor 220 from information acquirer 110, and may acquire illumination direction information 240 or reference illumination angle information 250 of the sensor when vehicle 210 is horizontal to the ground. Furthermore, controller 120 may acquire distance information 260 between sensor 220 and the ground measured by sensor 220 from information acquirer 110. Controller 120 may calculate illumination angle 270 of sensor 220 based on distance information 260 between sensor 220 and the ground and position information 230 of sensor 220. For example, controller 120 may calculate illumination angle 270 of sensor 220 based on a trigonometric function.
[0063] The controller 120 may compare the calculated illumination angle 270 of the sensor 220 with the reference illumination angle information 250 regarding the illumination angle of the sensor 220 when the vehicle 210 is horizontal with the ground, and may calculate the inclination of the vehicle 210 based on the comparison result. For example, the controller 120 may calculate the difference between the calculated illumination angle 270 of the sensor 220 and the reference illumination angle information 250 regarding the illumination angle of the sensor 220 when the vehicle 210 is horizontal with the ground, and may determine that the calculated difference is the inclination of the vehicle 210. In an embodiment, the controller 120 may generate a control signal for controlling the lamp based on the calculated inclination of the vehicle 210.
[0064] Return to reference Figure 3 , the controller 120 may generate a control signal for controlling the lamp to correct the illumination angle of the lamp according to the calculated inclination of the vehicle. For example, the controller 120 may generate a control signal to adjust the illumination angle of the lamp according to the calculated inclination of the vehicle. In this case, since the illumination angle of the lamp is corrected by the same amount as the inclination of the vehicle, the lamp may be able to illuminate light in a direction consistent with the illumination direction when the vehicle is horizontal to the ground.
[0065] In an embodiment, the light may include a first light and a second light. For example, the first light may be a right light of the vehicle, and the second light may be a left light of the vehicle. Furthermore, the sensor may include a first sensor and a second sensor. For example, the first sensor may be coupled or attached to the first light, and the second sensor may be coupled or attached to the second light.
[0066] The information acquirer 110 may acquire information about the sensor and distance information between the sensor and the ground for each of the first sensor and the second sensor. For example, the information acquirer 110 may acquire information about the first sensor, distance information between the first sensor and the ground, information about the second sensor, and distance information between the second sensor and the ground.
[0067] The controller 120 may calculate the slope based on the information obtained by the information acquirer 110 and may generate a control signal for controlling each lamp. For example, the controller 120 may calculate a first slope based on information about the first sensor and information about the distance between the first sensor and the ground, and may calculate a second slope based on information about the second sensor and information about the distance between the second sensor and the ground.
[0068] The controller 120 may generate a first control signal and a second control signal for controlling each of the first lamp and the second lamp based on the calculated first slope and the second slope. For example, the controller 120 may generate a first control signal for controlling the first lamp based on the calculated first slope, and may generate a second control signal for controlling the second lamp based on the calculated second slope. As another example, since the controller 120 calculates the slope relative to each of the first lamp and the second lamp and generates a control signal, the controller 120 may generate a control signal that allows the first lamp and the second lamp to be adjusted differently, respectively. That is, when only the first lamp is raised due to an obstacle and the second lamp is in a normal state, the controller 120 may generate a first control signal for controlling only the first lamp to lower the illumination angle, and may generate a second control signal for controlling the second lamp to maintain the illumination angle.
[0069] In an embodiment, the illumination angle of the sensor may be different from the illumination angle of the lamp. For example, the illumination angle of the sensor may be set to be lower than the illumination angle of the lamp.
[0070] Figure 5 2 is a diagram illustrating a lamp and a sensor according to an embodiment of the present disclosure.
[0071] Reference Figure 5, the illumination direction 330 of the lamp 310 may be set to be different from the illumination direction 340 of the sensor 320. For example, when the illumination direction 330 of the lamp 310 and the illumination direction 340 of the sensor 320 are set to be the same, there may be a situation where the sensor 320 cannot measure the distance between the ground and the sensor 320, and in this case, the controller 120 may not be able to calculate the inclination of the vehicle. That is, when the illumination direction 340 of the sensor 320 is lower than the illumination direction 330 of the lamp 310, the controller 120 may calculate the inclination of the vehicle and may generate a control signal for controlling the illumination angle of the lamp based on the calculated inclination.
[0072] Figure 6 is a flowchart illustrating a method of operating a light control apparatus according to an embodiment of the present disclosure.
[0073] The operating method of the light control device 100 according to an embodiment of the present disclosure may include: acquiring distance information between the sensor and the ground from a sensor of the vehicle (S110); acquiring information about the sensor (S120); calculating the inclination of the vehicle based on the information about the sensor and the distance information between the sensor and the ground (S130); and generating a control signal for controlling the light of the vehicle based on the calculated inclination of the vehicle (S140). In an embodiment, the method of operating the light control device may be performed by Figure 3 The light control device 100 executes.
[0074] In S110 of acquiring distance information between the sensor and the ground from the vehicle's sensor, the information acquirer 110 may acquire distance information between the sensor and the ground from the vehicle's sensor. For example, the sensor may measure the distance between the sensor and the ground, and the information acquirer 110 may acquire the measured distance information.
[0075] In S120 of acquiring information about the sensor, the information acquirer 110 may acquire information about the sensor. For example, the information acquirer 110 may acquire information about the sensor in advance before driving the vehicle, or may acquire information about the sensor from another device inside or outside the vehicle. For example, the information about the sensor may include position information of the sensor and reference illumination angle information about the illumination angle of the sensor when the vehicle is horizontal to the ground.
[0076] In S130 of calculating the inclination of the vehicle based on the information about the sensor and the distance information between the sensor and the ground, the controller 120 may calculate the inclination of the vehicle based on the information about the sensor and the distance information between the sensor and the ground acquired from the information acquirer 110. For example, the controller 120 may calculate the inclination of the vehicle based on the distance information between the sensor and the ground, the position information of the sensor, and reference illumination angle information regarding the illumination angle of the sensor when the vehicle is horizontal to the ground.
[0077] In S140 of generating a control signal for controlling the vehicle lights based on the calculated vehicle inclination, the controller 120 may generate the control signal for controlling the vehicle lights based on the calculated vehicle inclination. For example, since the lights may be raised or lowered when the vehicle is tilted, the controller 120 may generate the control signal for controlling the lights to correct the degree to which the lights are raised or lowered.
[0078] Figure 7 and Figure 8 is a flowchart illustrating in more detail a method of operating a light control apparatus according to an embodiment of the present disclosure.
[0079] Reference Figure 7 , a method for operating the light control device 100 according to an embodiment of the present disclosure may include: calculating the illumination angle of the sensor based on position information of the sensor and distance information between the sensor and the ground (S210); calculating the inclination of the vehicle by comparing reference illumination angle information with the calculated illumination angle of the sensor (S220); and generating a control signal for controlling the light to correct the illumination angle of the light by the calculated inclination of the vehicle (S230).
[0080] In S210 of calculating the illumination angle of the sensor based on the position information of the sensor and the distance information between the sensor and the ground, the controller 120 may calculate the illumination angle of the sensor based on the position information of the sensor and the distance information between the sensor and the ground. For example, the controller 120 may calculate the ratio of the position information of the sensor to the distance information between the sensor and the ground, and may calculate the illumination angle of the sensor corresponding to the calculated ratio. As another example, the controller 120 may calculate the illumination angle of the sensor based on a trigonometric function. In an embodiment, S210 may include Figure 6 The S130.
[0081] In S220 of calculating the inclination of the vehicle by comparing the reference illumination angle information with the calculated illumination angle of the sensor, the controller 120 may compare the reference illumination angle information with the calculated illumination angle of the sensor to calculate the inclination of the vehicle. For example, the controller 120 may calculate the difference between the reference illumination angle information about the illumination angle of the sensor when the vehicle is horizontal to the ground and the calculated illumination angle of the sensor, and may determine that the calculated difference in illumination angle is the inclination of the vehicle. In an embodiment, S220 may include Figure 6 The S130.
[0082] In S230 of generating a control signal for controlling the lamp to correct the illumination angle of the lamp by the calculated inclination of the vehicle, the controller 120 may generate a control signal for controlling the lamp to correct the illumination angle of the lamp by the calculated inclination of the vehicle. For example, since there is a possibility that the lamp may be raised or lowered when the vehicle is tilted, the controller 120 may generate a control signal that allows the lamp to be raised or lowered by the inclination of the vehicle. In an embodiment, the control signal generated by the controller 120 may be transmitted to a device for controlling the operation of the lamp, and the device for controlling the operation of the lamp may move the lamp up and down in response to the control signal. In an embodiment, S230 may include Figure 6 S140.
[0083] Reference Figure 8 According to an embodiment of the present disclosure, the operating method of the light controlling device 100 may include calculating a first slope based on information about a first sensor and distance information between the first sensor and the ground (S310), calculating a second slope based on information about a second sensor and distance information between the second sensor and the ground (S320), and generating a first control signal and a second control signal for controlling a first light and a second light respectively based on the calculated first slope and second slope (S330).
[0084] In an embodiment, the light may include a first light and a second light, and the sensor may include a first sensor coupled or attached to the first light and a second sensor coupled or attached to the second light. For example, the first light may be a right headlight of the vehicle, and the second light may be a left headlight of the vehicle. That is, the information acquirer 110 may acquire information about the first sensor, distance information between the first sensor and the ground, information about the second sensor, and distance information between the second sensor and the ground ( Figure 6 S110 and S120).
[0085] In S310 of calculating the first slope based on the information about the first sensor and the distance information between the first sensor and the ground, the controller 120 may calculate the first slope based on the information about the first sensor and the distance information between the first sensor and the ground. For example, the controller 120 may calculate the illumination angle of the first sensor based on the position information of the first sensor and the distance information between the first sensor and the ground, and may calculate the first slope by comparing the illumination angle of the first sensor with the reference illumination angle information of the first sensor. In an embodiment, S310 may include Figure 6 The S130.
[0086] In S320 of calculating the second slope based on the information about the second sensor and the distance information between the second sensor and the ground, the controller 120 may calculate the second slope based on the information about the second sensor and the distance information between the second sensor and the ground. For example, the controller 120 may calculate the illumination angle of the second sensor based on the position information of the second sensor and the distance information between the second sensor and the ground, and may calculate the second slope by comparing the illumination angle of the second sensor with the reference illumination angle information of the second sensor. In an embodiment, S320 may include Figure 6 The S130.
[0087] In step S330 of generating a first control signal and a second control signal for controlling each of the first and second lamps based on the calculated first and second inclinations, the controller 120 may generate the first control signal for controlling the first lamp based on the calculated first inclination, and may generate the second control signal for controlling the second lamp based on the calculated second inclination. For example, since the illumination directions of the first and second lamps may be different depending on the respective inclinations, the controller 120 may separately generate the first control signal for controlling the first lamp and the second control signal for controlling the second lamp.
[0088] According to an embodiment of the present disclosure, the light controlling apparatus may calculate the inclination of the vehicle based on information about the sensor and information obtained from the sensor, and may generate a control signal for controlling the light to correct an illumination angle of the light based on the calculated inclination of the vehicle.
[0089] In addition, various effects recognized directly or indirectly through the document can be provided.
[0090] The above description merely illustrates the technical idea of the present disclosure, and a person skilled in the art to which the present disclosure pertains will be able to make various modifications and variations without departing from the essential characteristics of the present disclosure.
