Description

Technical Field

[0001] The present invention relates to an optical device for vehicles, and more specifically, to an optical device for vehicles capable of preventing abnormal sensing due to changes in the direction of travel of light entering from outside the vehicle. Background Technology

[0002] Vehicles typically provide people with the convenience of movement and time efficiency, but due to driver inattention, they can cause harm not only to the driver but also to those around them. Therefore, vehicles are equipped with various sensors, such as cameras or lidar, to detect hazards around the vehicle.

[0003] Optical sensors such as cameras or lidar can receive light reflected from objects around a vehicle to generate images of the vehicle's surroundings or sense the position or distance of objects around the vehicle. Based on the sensing results, they can inform the driver of dangerous situations, enabling the driver to respond quickly to dangerous situations.

[0004] At this time, before the light entering from outside the vehicle is received by the optical sensor, the optical sensor may change the direction of light travel depending on the setting position. If the direction of light travel changes, the accuracy of the sensing results of the optical sensor may decrease. Therefore, a solution is required that can correct for this if the direction of light travel changes before the light entering from outside the vehicle is received by the optical sensor. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an optical device for a vehicle that can correct the direction of light travel when the direction of light travels changes before receiving light entering from outside the vehicle.

[0006] The technical problems to be solved by the present invention are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned through the following description.

[0007] To address the aforementioned technical problem, an optical device for vehicles according to an embodiment of the present invention may include: an optical sensor module for sensing light traveling through a light transmission component; and a correction optical system having at least one optical component that refracts light traveling between the light transmission component and the optical sensor module in a direction different from the direction refracted by the light transmission component.

[0008] The optical sensor module may include at least one of a camera and a lidar.

[0009] The at least one optical component may be formed asymmetrically in at least one direction with reference to the optical axis of the optical sensor module.

[0010] One of the corrective optical system and the light transmission component can converge the transmitted light, while the other can diverge the transmitted light.

[0011] The corrective optical system can refract light in a direction opposite to that refracted by the light-transmitting component.

[0012] When the refractive power of the light transmission component changes due to deformation caused by ambient temperature, the correction optical system can compensate for the change in refractive power.

[0013] In the corrected optical system, at least one optical component can deform according to the ambient temperature to compensate for the changing refractive force.

[0014] In the corrective optical system, the position of at least one optical component can be adjusted according to the ambient temperature to compensate for the changing refractive force.

[0015] The position of the at least one optical component can be adjusted by at least one of linear movement and rotational movement.

[0016] In the corrective optical system, at least one optical component can be fixed to a fixed component that deforms according to the ambient temperature. When the fixed component deforms, the position of the at least one optical component can be adjusted to compensate for the changing refractive force.

[0017] The optical sensor module may further include: a light-emitting module that generates light toward the light-transmitting component, wherein the correction optical system can refract the light generated from the light-emitting module in a direction different from the direction refracted by the light-transmitting component.

[0018] The corrective optical system can refract light generated from the light-emitting module in a direction opposite to that refracted by the light-transmitting component.

[0019] The correction optical system can be divided into a region that refracts light that passes through the light transmission component and is directed toward the optical sensor module, and a region that refracts light generated from the light emission module toward the light transmission component.

[0020] The at least one optical component may include at least one of a lens, a mirror, and a prism.

[0021] The light transmission component and the correction optical system may have chromatic aberration patterns that are opposite to each other.

[0022] The corrected optical system can have a transmittance of more than 50% for the wavelengths of light entering from outside the vehicle that need to be sensed by the optical sensor module or for the wavelengths of light generated by the optical sensor module that need to be irradiated to the outside of the vehicle.

[0023] Other specific aspects of the invention are included in the detailed description and accompanying drawings.

[0024] The vehicle optical device according to the present invention as described above has one or more of the following effects.

[0025] It has the following effect: when the direction of light travels changes before the optical sensor module senses light entering from outside the vehicle, it corrects for this, thereby enabling accurate sensing.

[0026] Furthermore, it also has the following effect: even when the light generated by the optical sensor module senses light reflected from objects around the vehicle, it can correct for changes in the direction of travel of the light generated by the optical sensor module.

[0027] The effects of this invention are not limited to those mentioned above, and those skilled in the art can clearly understand other effects not mentioned through the description of the claims. Attached Figure Description

Throughout the specification, the same reference numerals denote the same constituent elements.

[0039] Hereinafter, the present invention will be described with reference to the accompanying drawings illustrating the optical device for a vehicle, through embodiments thereof.

[0040] Figure 1 This is a schematic diagram illustrating the configuration of a vehicle optical device according to an embodiment of the present invention.

[0041] Reference Figure 1 According to an embodiment of the present invention, the vehicle optical device 1 may include an optical sensor module 100 and a correction optical system 200.

[0042] In embodiments of the present invention, the vehicle optical device 1 can be used to receive light reflected from objects around the vehicle and convert it into image data, or to sense the position or distance of objects, etc., and sunlight or light generated from the vehicle optical device 1 of the present invention can be reflected from objects around the vehicle and received.

[0043] The optical sensor module 100 may include a light receiving sensor 110 and at least one optical element 120.

[0044] The light receiving sensor 110 can be understood as an image sensor such as a charge-coupled device (CCD), complementary metal-oxide semiconductor (CMOS), photodiode (PD), etc. At least one optical element 120 can direct light entering from the outside of the vehicle along an appropriate direction of travel, thereby enabling sensing by the light receiving sensor 110.

[0045] In an embodiment of the present invention, an example is given of using a plurality of lenses arranged along the optical axis Ax of the vehicle optical device 100 of the present invention as at least one optical element 120, but it is not limited thereto. At least one optical element 120 may use a variety of optical elements such as lenses, mirrors, prisms, etc., that can affect the direction of light travel.

[0046] At this time, since the optical sensor module 100 is usually designed under the condition that the light entering from the outside of the vehicle travels parallel to the optical axis Ax of the vehicle optical device 1 of the present invention, there is a possibility that the light travel direction may be abnormally sensed before the optical sensor module 100 receives the light due to external factors.

[0047] In an embodiment of the present invention, if the direction of light travels changes before the optical sensor module 100 receives light, the direction of light travels is corrected by the optical correction system 200, so that the optical sensor module 100 can perform normal sensing.

[0048] That is, when the optical sensor module 100 is located inside the vehicle or inside the external lamp, light entering from outside the vehicle may be refracted by the windshield or the cover lens of the external lamp, etc. In this case, the optical sensor module 100 may perform abnormal sensing. Therefore, in the embodiment of the present invention, when the direction of light travel is changed by the windshield or the cover lens, the direction of light travel is corrected by the correction optical system 200, so that the optical sensor module 100 can perform normal sensing.

[0049] Figure 2 This is a schematic diagram illustrating the direction of light travel received by a vehicle optical device according to an embodiment of the present invention.

[0050] Reference Figure 2 According to the embodiment of the present invention, the optical sensor module 100 is positioned such that the light transmission component 300, such as the windshield or cover lens, is located in front of the optical sensor module 100. This may result in the possibility that light entering from outside the vehicle is refracted. If the direction of light travel is not corrected by the correction optical system 200, the optical sensor module 100 may perform abnormal sensing.

[0051] That is, when there is no light transmission component 300 in front of the optical sensor module 100 to refract light entering from outside the vehicle, the light L1 entering from outside the vehicle travels parallel to the optical axis Ax of the optical sensor module 100 and is received. Conversely, when there is a light transmission component 300 in front of the optical sensor module 100, the light L1 entering from outside the vehicle is refracted and travels in parallel. In this case, there is a possibility that the optical sensor module 100 will perform abnormal sensing.

[0052] In an embodiment of the present invention, a correction optical system 200 is provided between the optical sensor module 100 and the light transmission component 300, so that the light L1 entering from the outside of the vehicle is refracted in a direction different from the direction refracted by the light transmission component 300. As a result, similar to the case where no light transmission component 300 is provided in front of the optical sensor module 100, the light is received in a direction that is parallel to the optical axis Ax of the optical sensor module 100 and travels towards the optical sensor module 100.

[0053] In an embodiment of the present invention, an example is given where the corrective optical system 200 refracts light in a direction opposite to that refracted by the light transmission component 300. However, this is only an example to help understand the present invention and is not limited thereto. The corrective optical system 200 can refract light entering from outside the vehicle in the same direction as the light transmission component 300 and with different refraction angles, depending on the position of the optical sensor module 100 or the shape of the light transmission component 300, so that the light travels parallel to the optical axis Ax of the optical sensor module 100.

[0054] Furthermore, in the embodiments of the present invention, the case in which the correction optical system 200 is constructed using a single lens and is equipped independently of the optical sensor module 100 is described as an example, but it is not limited thereto. The correction optical system 200 may include not only a lens, but also one or more optical components such as mirrors or prisms that can correct the direction of light travel. The correction optical system 200 may be integrated with the optical sensor module 100 or the light transmission component 300.

[0055] The integration of the correction optical system 200 with the optical sensor module 100 or the light transmission component 300 can include not only the case where they are manufactured as a single unit, but also the case where they are separately equipped and combined with each other in a manner without relative movement.

[0056] To improve sensing efficiency, the calibration optical system 200 can have a transmittance of more than 50% for wavelengths of light that need to be sensed by the optical sensor module 100 from outside the vehicle or wavelengths of light that need to be irradiated from outside the vehicle from the optical sensor module 100.

[0057] At this time, the reason why the correction optical system 200 has a transmittance of more than 50% for wavelengths that need to be irradiated to the outside of the vehicle is that, in the case of the vehicle optical device 1 of the present invention being used for applications such as lidar for sensing the position or distance of objects around the vehicle, the optical sensor module 100 can function to sense light entering from the outside of the vehicle while generating light for sensing objects around the vehicle.

[0058] One of the correction optical system 200 and the light transmission component 300 can be designed to converge the transmitted light, and the other can be designed to diverge the transmitted light, so that the light emitted from or received by the optical sensor module 100 travels in a manner parallel to the optical axis Ax of the optical sensor module 100.

[0059] Furthermore, the correction optical system 200 and the light transmission component 300 may have opposite chromatic aberration patterns to correct the chromatic aberration caused by wavelength differences when light emitted from or received by the optical sensor module 100 is transmitted through the correction optical system 200 and the light transmission component 300.

[0060] The aforementioned correction optical system 200 can be formed asymmetrically in at least one direction with the optical axis Ax of the optical sensor module 100 as a reference. This is because most of the light transmission components 300, such as windshields or cover lenses, have a shape that is a straight line, a curve, or a combination thereof with a predetermined tilt angle with respect to a direction perpendicular to the optical axis Ax of the optical sensor module 100, based on the vehicle body lines. However, it is not limited to this. The correction optical system 200 can also be formed symmetrically with respect to the optical axis Ax of the optical sensor module 100 based on the shape of the light transmission component 300.

[0061] At this point, the asymmetric formation of the correction optical system 200 can be understood as a difference in at least one of the size and curvature in at least one direction, with reference to the optical axis Ax of the optical sensor module 100.

[0062] Furthermore, the correction optical system 200 can be configured such that the incident angle of the light traveling between the optical sensor module 100 and the light transmission component 300 is below the critical angle of total internal reflection, in order to prevent noise from being generated due to the total internal reflection of the light by the correction optical system 200.

[0063] That is, if at least a portion of the light entering from outside the vehicle is totally reflected by the correction optical system 200 or at least a portion of the light generated from the optical sensor module 100 is totally reflected by the correction optical system 200, noise will be generated in the sensing result of the optical sensor module 100, which may lead to abnormal sensing. Therefore, the correction optical system 200 is configured such that the incident angle of the light entering from outside the vehicle and the incident angle of the light generated from the optical sensor module 100 are 45 degrees or less, thereby preventing noise from being generated due to total internal reflection.

[0064] Furthermore, to improve sensing efficiency, the optical sensor module 100 is preferably configured with a sensing range HFOV of 60 degrees or more in one direction, with the optical axis Ax as a reference. Therefore, in embodiments of the present invention, such as... Figure 3 As shown, when the distance between the optical sensor module 100 and the calibration optical system 200 is called L and the radius of the calibration optical system 200 is called H, it can be designed so that L / H≤0.577.

[0065] In the vehicle optical device 1 of the present invention as described above, when the refractive power of the light transmission component 300 changes due to deformation caused by the ambient temperature, the changed refractive power can be compensated.

[0066] That is, such as Figure 4 As shown, under conditions of rising ambient temperature, the light transmission component 300 may expand; conversely, as... Figure 5 As shown, when the ambient temperature drops, the light transmission component 300 may shrink. When the light transmission component 300 deforms according to the ambient temperature, the refractive power of the light transmission component 300 changes. Therefore, the change in refractive power is compensated by the correction optical system 200.

[0067] at this time, Figure 4 and Figure 5 The dashed line in the figure represents the light transmission component 300 before deformation according to the ambient temperature, and is used to show the difference between the light transmission component 300 before deformation according to the ambient temperature.

[0068] The following is for reference Figures 6 to 10 The description details how the optical system 200 compensates for the changes in refractive power of the light transmission component 300.

[0069] Figure 6An example of the following situation is that the correction optical system 200 is movably disposed on the track 410, and when the drive unit 500 is driven, the correction optical system 200 moves along the track 410 to adjust the position of the correction optical system 200, thereby compensating for the changing refractive force of the light transmission component 300.

[0070] Figure 7 Here is an example of a situation where the correction optical system 200 is disposed on the movable moving part 420, and when the driving part 500 is driven, the position of the correction optical system 200 is adjusted as the moving part 420 moves, thereby compensating for the changing refractive force of the light transmission part 300.

[0071] Figure 8 An example is as follows: the correction optical system 200 is movably disposed in the guide groove 431 formed in the rotating member 430, and the position of the correction optical system 200 is adjusted by means of the guide groove 431 when the rotating member 430 rotates.

[0072] That is, the rotating member 430 can be configured such that the guide groove 431 extends from one end to the other end in the direction of the rotation axis of the rotating member 430 while rotating around the rotation axis of the rotating member 430. Thus, when the rotating member 430 rotates, the correction optical system 200 can move between the two ends of the rotating member 430 to adjust its position.

[0073] Figure 9 and Figure 10 Here is an example of a situation where the correction optical system 200 is fixed to a fixed component 440, which, like the light transmission component 300, deforms according to the ambient temperature, and the position of the correction optical system 200 is determined according to... Figure 9 As shown, the fixed component 440 expands or, as the ambient temperature rises... Figure 10 As shown, the fixed component 440 is adjusted by shrinking as the ambient temperature decreases.

[0074] In the above Figures 6 to 10 The example described is the case where the position of the correction optical system 200 is adjusted by linear movement, but it is not limited to this. The position of the correction optical system 200 can be adjusted by linear movement, rotational movement or a combination thereof.

[0075] Furthermore, the structure used to adjust the position of the correction optical system 200 is not limited to the example described above, and various structures capable of adjusting the position of the correction optical system 200 according to the ambient temperature can be used.

[0076] In addition, in the above Figures 6 to 10The example given is the case where the position of the correction optical system 200 is adjusted to compensate for the change in refractive power of the light transmission component 300. However, it is not limited to this. The correction optical system 200 and the light transmission component 300 can also be made of a resin material that can deform according to the ambient temperature. When the light transmission component 300 expands or contracts, the correction optical system 200 can also expand or contract to compensate for the change in refractive power of the light transmission component 300.

[0077] In the above embodiments, the case in which the position of the correction optical system 200 is adjusted according to the ambient temperature or the correction optical system 200 is deformed to compensate for the change in refractive force due to the deformation of the light transmission component 300 is described, but it is not limited to this. When the ambient temperature is sensed by a temperature sensor to maintain a predetermined temperature range, the position of the correction optical system 200 can be fixed.

[0078] For example, when the ambient temperature is sensed by a temperature sensor and a heater or cooling fan is operated according to the sensed ambient temperature to keep the ambient temperature within a predetermined temperature range, the position of the correction optical system 200 can be fixed.

[0079] In the above embodiments, the vehicle optical device 1 of the present invention is described as an example of receiving light entering from outside the vehicle. However, it is not limited to this. When the vehicle optical device 1 of the present invention is used as a lidar or other device for sensing the position or distance of objects around the vehicle, it can be equipped with not only a light receiving function but also a light emitting function.

[0080] Figure 11 This is a schematic diagram illustrating the configuration of a vehicle optical device according to another embodiment of the present invention.

[0081] Reference Figure 11 Similar to the embodiments described above, the vehicle optical device 1 according to another embodiment of the present invention may include an optical sensor module 100 and a correction optical system 200.

[0082] In another embodiment of the present invention, the optical sensor module 100 may include not only a light receiving function, but also a light emitting function. For this purpose, in addition to the light receiving sensor 110 and at least one optical element 120, the optical sensor module 100 may also include a light emitting module 130.

[0083] For example, the light-emitting module 130 can generate light such as pulsed laser light, and the light generated by the light-emitting module 130 can be reflected from objects around the vehicle and received by the light receiving sensor 110.

[0084] At this time, the light generated from the light-emitting module 130 can also be refracted by the light transmission component 300 in the same way as the light entering from outside the vehicle, thus changing the direction of light travel. When the direction of light travel is changed by the light transmission component 300, the accuracy of the position or distance of objects around the vehicle is reduced, thereby increasing the possibility of a vehicle accident.

[0085] Therefore, in another embodiment of the present invention, the correction optical system 200 refracts the light generated from the light-emitting module 130 in a direction different from that refracted by the light-transmitting component 300, so that the light generated from the light-emitting module 130 travels parallel to the optical axis Ax of the vehicle optical device 1 of the present invention, thereby enabling accurate sensing of the position or distance of objects around the vehicle.

[0086] Therefore, the correction optical system 200 can be divided into a region A1 for correcting the direction of travel of light traveling toward the light receiving sensor 110 and a region A2 for correcting the direction of travel of light generated from the light emitting module 130. Thus, it is possible to correct the direction of travel of light received from the light receiving sensor 110 and the direction of travel of light generated from the light emitting module 130.

[0087] In another embodiment of the present invention, an example is given of correcting the direction of travel of light entering from outside the vehicle and the direction of travel of light generated from the light-emitting module 130 by a single correction optical system 200. However, it is not limited to this. In order to correct the direction of travel of light entering from outside the vehicle and the direction of travel of light generated from the light-emitting module 130, a correction optical system 200 may also be provided separately.

[0088] Figure 12 This is a schematic diagram showing the direction of travel of light emitted from a vehicle optical device according to another embodiment of the present invention.

[0089] Reference Figure 12 Light L2 generated from the light-emitting module 130 of the optical sensor module 100 according to another embodiment of the present invention can be refracted by the correction optical system 200 in a direction different from that of the light-transmitting component 300, and can travel parallel to the optical axis Ax of the vehicle optical device 1 according to the present invention.

[0090] At this time, Figure 12 In this case, the optical system 200 corrects the light generated from the light-emitting module 130 to be refracted in the opposite direction to the direction refracted by the light-transmitting component 300. However, it is not limited to this. The optical system 200 can make the light generated from the light-emitting module 130 refract in the same direction as the direction refracted by the light-transmitting component 300, and have different refraction angles, depending on the position of the vehicle optical device 1 of this disclosure.

[0091] As described above, in the vehicle optical device 1 of the present invention, when the direction of travel of light emitted from or received by the optical sensor module 100 is changed by the refraction of the light transmission member 300 located in front of the optical sensor module 100, the direction of travel of light is corrected by the correction optical system 200, thereby preventing abnormal sensing and significantly reducing the possibility of vehicle accidents.

[0092] Those skilled in the art will understand that the invention can be implemented in other specific forms without altering its technical concept or essential features. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of the invention is defined by the claims, not by the detailed description above, and all changes or modifications derived from the meaning, scope, and equivalents of the claims should be interpreted as included within the scope of the invention.
