Description

Technical Field

[0001] The present specification relates to an imaging device for a vehicle, and more particularly, to a personalized infotainment device for a vehicle. Background Art

[0002] A vehicle is a device that moves in a direction desired by a user who rides in it. A typical example is an automobile.

[0003] On the other hand, in order to facilitate the users who use the vehicle, the trend is to install various sensors and electronic devices, etc. In particular, in order to facilitate the user's driving, the research of vehicle driver assistance system (ADAS: Advanced Driver Assistance System) is being actively carried out. In addition, the development of autonomous vehicles is being actively carried out.

[0004] On the other hand, the vehicle display that displays various driving information of the vehicle is located below the driver's front driving field of view, which affects driving safety, i.e., rubber necking. Therefore, recently, a vehicle imaging device that ensures driving safety by realizing an image on the windshield in front of the vehicle close to the driving field of view, such as a HUD (Head up display), can be installed in the vehicle.

[0005] In addition, it is necessary to implement an infotainment device for providing personal information and personal entertainment content in the front passenger seat or rear seat of the vehicle. Therefore, it is necessary to display driving-related information in the front area of ​​the driver's seat of the vehicle or to provide a vehicle imaging device for providing personal entertainment content in the front area of ​​the front passenger seat or rear seat of the vehicle.

[0006] Unlike the back seat, there is no personal entertainment display in the front passenger seat of the vehicle. There is no suitable space to install a display in the front passenger seat. In addition, for the sake of driving stability of the driver, there is a restriction that the image displayed on the entertainment device cannot enter the driver's field of vision, and there are some relevant laws and regulations related to it.

[0007] Therefore, it is necessary to propose a technology that appropriately configures a large-screen infotainment video device that can be used to provide personal entertainment and various information to the front passenger seat so that only the front passenger seat passenger can view it. Thus, it is expected that the front passenger seat passenger can enjoy various information and entertainment in the vehicle through a new large-screen video device for vehicles that does not exist in the prior art. Summary of the invention

[0008] Problems to be solved by the invention

[0009] The purpose of this specification is to provide a personalized infotainment device for a vehicle.

[0010] In addition, the present specification aims to provide an imaging device that can realize a personal infotainment display without the space problem of the front passenger seat of the vehicle and the driver's safety problem.

[0011] In addition, the purpose of this specification is to provide a method for appropriately configuring a large-screen infotainment video device that can provide personal entertainment and various information even in the front passenger seat so that only the passenger in the front passenger seat can view it.

[0012] In addition, the present specification aims to provide a personalized infotainment device for a vehicle that is small in size and invisible from a driver's seat.

[0125] The user interface device 200 can operate according to the control of the control unit 170 .

[0126] The object detection device 300 is a device for detecting an object located outside the vehicle 100 .

[0127] The object may be various objects related to the operation of the vehicle 100 .

[0128] On the other hand, the vehicle imaging device of this specification, in particular, the vehicle personalized infotainment device is described. In this regard, the vehicle display that displays various driving information of the vehicle is located below the front driving field of view of the driver, which affects the driving safety, i.e., rubber necking. Therefore, recently, a vehicle imaging device that ensures driving safety by realizing an image on the windshield in front of the vehicle near the driving field of view, such as a HUD (Head up display), can be installed in the vehicle.

[0129] In addition, it is necessary to implement an infotainment device for providing personal information and personal entertainment content in the front passenger seat or rear seat of the vehicle. Therefore, it is necessary to display driving-related information in the front area of ​​the driver's seat of the vehicle or to provide a vehicle imaging device for providing personal entertainment content in the front area of ​​the front passenger seat or rear seat of the vehicle.

[0130] Unlike the back seat, there is no personal entertainment display in the front passenger seat of the vehicle. There is no suitable space to install a display in the front passenger seat. In addition, for the sake of driving stability of the driver, there is a restriction that the image displayed on the entertainment device cannot enter the driver's field of vision, and there are some relevant laws and regulations related to it.

[0131] Therefore, it is necessary to propose a technology that appropriately configures a large-screen infotainment video device that can be used to provide personal entertainment and various information to the front passenger seat so that only the front passenger seat passenger can view it. Thus, it is expected that the front passenger seat passenger can enjoy various information and entertainment in the vehicle through a new large-screen video device for vehicles that does not exist in the prior art.

[0132] In this regard, the purpose of this specification is to provide a personalized infotainment device for a vehicle. In addition, the purpose of this specification is to provide an image device that can realize a personal infotainment display without the space problem of the front passenger seat of the vehicle and the driver's safety problem. In addition, the purpose of this specification is to provide a method for appropriately configuring a large-screen infotainment image device that can also be used to access personal entertainment and various information in the front passenger seat so that only the passenger in the front passenger seat can view it.

[0133] In addition, the purpose of this specification is to provide a personalized vehicle infotainment device that is small and invisible from the driver's seat. The subject of the present invention is not limited to the above-mentioned subject, and those skilled in the art can clearly understand other unmentioned subjects through the following description.

[0134] With reference to the accompanying drawings, the vehicle imaging device of the present specification, especially the vehicle personalized infotainment device, for achieving the aforementioned purpose is described in detail. In this regard, Figure 6a This diagram shows a configuration in which a screen having a predetermined ratio is formed in a specific area of ​​the front glass of a vehicle. Figure 6b Indicates that it is used to implement Figure 6a A vehicle imaging device having a screen of a predetermined ratio is configured inside a dashboard of a vehicle.

[0135] on the other hand, Figure 7a and Figure 7b express Figure 6b The image forming device and a plurality of internal components of the vehicle imaging device are arranged inside a cover. Figure 8a express Figure 7a In the vehicle imaging device, an image forming device is arranged in the front area of ​​the screen panel. Figure 8b express Figure 7a In the vehicle imaging device, an image forming device is arranged in the front area of ​​the screen panel.

[0136] Reference Figure 6a , an image having a width Wa in one axis direction and a length La in another axis direction may be displayed in a specific area 251R of the windshield of the vehicle. The image may be displayed in a specific area of ​​the windshield of the front passenger seat in the vehicle. The image displayed in the specific area of ​​the windshield of the front passenger seat may be displayed such that the width Wa in one axis direction is greater than the length La in the other axis direction.

[0137] Reference Figures 6a to 7bThe vehicle imaging device 1000 of the present specification can be implemented by a personalized infotainment display (PID) for a user sitting in the front passenger seat of the vehicle. The personalized infotainment display (PID) can be implemented by a large screen having a specified width or a specified length or more for the passenger seat. The personalized infotainment display (PID) can provide entertainment content and internet browsing functions, and the entertainment content provides content such as movies / sports / music. The personalized infotainment display (PID) can provide driving assistance functions such as navigation. The personalized infotainment display (PID) can provide document browsing & editing and mobile connecting functions.

[0138] Reference Figures 6a to 7b , the vehicle imaging device 1000 may include a cover 1010, an image forming device (Picture Generation Unit, PGU) 1100, a screen panel 1200 and a mirror 1300. The vehicle imaging device 1000 may be arranged in the interior area of ​​the vehicle, avoiding the vehicle's internal structures such as the glove box, air conditioning device, and airbag. The vertical height hv from the lower end of the image forming device (PGU) 1100 to the end of the cover 1010 may be achieved within a prescribed range of about 100 mm, but is not limited thereto. The width W1 of the screen panel 1200 in one axial direction may be achieved within a range of about 280 to 420 mm, but is not limited thereto. The length L1 of the screen panel 1200 in another axial direction may be achieved within a range of about 360 to 540 mm, but is not limited thereto.

[0139] Reference Figure 7a The image forming unit (PGU) 1100 arranged along one axis direction may be implemented by a front surface structure. The PGU 1100 may be arranged to be separated from one end or the other end of the screen panel 1200. Light emitted from the PGU 1100 may be reflected from the mirror 1300 on the upper portion of the PGU 1100 and the screen panel 1200.

[0140] Reference Figure 7b, the image forming unit (PGU) 1100 arranged along another axis direction may be implemented by a side surface structure. The PGU 1100 may be arranged to be separated from the side end, that is, the left end or the right end, of the screen panel 1200. The light emitted from the PGU 1100 may be reflected from the mirror 1300 on the side of the PGU 1100 and the screen panel 1200.

[0141] The cover 1010 may form the appearance of a dashboard of the vehicle and be disposed at the front passenger seat of the vehicle. The image forming device (PGU: Picture Generation Unit) 1100 may be disposed inside the dashboard. The image forming device 1100 forms light in an upward direction or to one side, so that an image can be displayed in a specific area within the field of vision of the user sitting in the front passenger seat.

[0142] A mirror 1300 may be disposed between the image forming device and the cover. The mirror 1300 may reflect light formed by the image forming device 1100 toward an upper direction or one side. The light reflected by the mirror 1300 is reflected from the screen panel 1200, so that an image may be displayed in a specific area 251R of the windshield of the vehicle. The mirror 1300 may be formed of a short-focus mirror, but is not limited thereto.

[0143] A screen panel 1200 may be disposed between the image forming device 1100 and the mirror 1300. The screen panel 1200 may reflect the light reflected by the mirror 1300 and allow an image generated by the reflected light to pass through the cover 1010. The screen panel 1200 and the mirror 1300 may be designed so that the image generated by the image forming device 1100 can be imaged on the screen panel 1200 even within a short projection distance of a prescribed distance or less through the mirror 1300. The image projected at the short projection distance may be formed to be reflected from the screen panel 1200 designed at an angle so as to be visible only to the passenger in the front passenger seat.

[0144] An image generated by light reflected from the screen panel 1200 may be displayed in a specific area 251R of the windshield of the front passenger seat. The image displayed in the specific area 251R of the windshield of the front passenger seat may be displayed such that a width Wa in one axial direction is greater than a length La in another axial direction. One end of the image displayed in the specific area 251R of the windshield of the front passenger seat may be set to be beyond the field of vision of the vehicle driver.

[0145] In order to avoid the internal structures of the vehicle such as the glove box, air conditioner, and airbag, the vehicle imaging device 1000 can be applied with a special screen panel and a short-focus mirror designed to be thin and small. An operation panel can be arranged on the right door armrest of the front passenger seat so that the front passenger seat passenger can easily operate the vehicle imaging device 1000. The display of the image displayed in the specific area 251R of the windshield of the front passenger seat and the playback of the content can be performed by the operation panel arranged on the front passenger seat.

[0146] The width Wa and length La of the image displayed in the specific area 251R of the windshield of the passenger seat may be related to the first width W1 and length L1 of the screen panel 1200. In this regard, the screen panel 1200 may form a first width W1 along one axis direction and a first length L1 along another axis direction inside the instrument panel. The ratio of the first width W1 and the first length L1 of the screen panel 1200 may be formed as a first ratio. The ratio of the width Wa and the length La of the image displayed on the windshield may be formed as a second ratio.

[0147] The upper end of the image displayed on the windshield of the passenger seat may be arranged below the center line of the windshield. The first ratio of the first width W1 and the first length L1 of the screen panel 1200 may be set to be greater than 5:1. Thus, the second ratio of the width Wa and the length La of the image displayed on the windshield may also be set to be greater than 5:1.

[0148] On the other hand, the cover 1010 of the vehicle imaging device 1000 of the present specification may include: a transmission area (or transparent area) that transmits a light signal including an image; and an opaque area (or opaque area) in which a plurality of internal components are arranged. Figure 7a and Figure 7b , the cover 1010 may include an opaque area 1010a and a transparent area 1010b.

[0149] Reference Figures 6a to 7b , the opaque area 1010a may be formed in one side area and / or the other side area corresponding to the area where the image forming device 1100 and the mirror 1300 are configured. The transparent area 1010b may be formed corresponding to the area where the screen panel 1200 is configured. The opaque area 1010a may be formed to surround the transparent area 1010b. The image formed by reflection from the screen panel 1200 may be displayed in a specific area 251R of the windshield of the passenger seat through the transparent area 1010b of the cover 1010.

[0150] On the other hand, the image forming device (PGU) 1100 of the vehicle imaging device 1000 of the present specification may be implemented by a front PGU structure spaced apart from one end of the screen panel 1200 or a rear PGU structure spaced apart from the other end. Figures 6a to 8a The image forming device 1100 may be formed by a front PGU structure that is spaced apart from one end of the screen panel 1120 and disposed adjacent to a user sitting in a passenger seat. Thus, one end of the screen panel 1120 may be formed at a distance closer to the passenger seat than the other end.

[0151] The light reflected by the mirror 1300 and the screen panel 1200 can be reflected to different areas of the windshield at multiple reflection angles different from each other. Thus, an image can be formed within the field of vision of a user or passenger sitting in the front passenger seat. The different areas of the windshield may include an area from a first position P1 adjacent to one end of the screen panel 1120 to a second position P2 adjacent to the other end. The length from the first position P1 to the second position P2 forming the different areas of the windshield can correspond to the length La of the other axial direction of the specific area 251R of the windshield. The vertical distance between the cover 1010 and the screen panel 1200 can be formed so that the vertical distance at the other end of the screen panel 1120 is shorter than the vertical distance at the end of one side.

[0152] Reference Figure 6a and Figure 8b The image forming device 1100 may be formed by a rear PGU structure that is spaced from the other end of the screen panel 1120 and arranged at a distance far from the user sitting in the passenger seat. Thus, the other end of the screen panel 1120 may be formed at a distance farther from the passenger seat than the one end.

[0153] The light reflected by the mirror 1300 and the screen panel 1200 can be reflected to different areas of the windshield at multiple reflection angles different from each other. Thus, an image can be formed within the field of vision of a user or passenger sitting in the front passenger seat. The different areas of the windshield may include an area from a first position P1 adjacent to one end of the screen panel 1120 to a second position P2 adjacent to the other end. The length from the first position P1 to the second position P2 forming the different areas of the windshield can correspond to the length La in the other axial direction of the specific area 251R of the windshield. The vertical distance between the cover 1010 and the screen panel 1200 can be formed so that the vertical distance at the other end of the screen panel 1120 is farther than the vertical distance at one end.

[0154] Reference Figures 6a to 8a In the front PGU structure, the mirror 1300 can be formed into a curved shape or a flat shape. Figure 6b to Figure 7b One side of the mirror 1300 adjacent to one end of the screen panel 1200, on which the light formed by the image forming device 1100 is incident, may be formed in a curved shape. The mirror 1300 formed in a curved shape may be tilted toward the screen panel 1200 at a predetermined angle with respect to the vertical axis. The screen panel 1200 may be formed in an inclined structure in which one end is arranged at a lower position than the other end on the vertical axis.

[0155] Reference Figure 8a One side of the mirror 1300 adjacent to one end of the screen panel 1200, on which the light formed by the image forming device 1100 is incident, may be formed in a flat shape. The mirror 1300 formed in a flat shape may be tilted toward the screen panel 1200 at a predetermined angle with respect to the vertical axis. The screen panel 1200 may be formed so that one end and the other end are formed at the same position on the vertical axis and are arranged horizontally.

[0156] Reference Figure 8b One side of the mirror 1300 adjacent to the other end of the screen panel 1200, on which the light formed by the image forming device 1100 is incident, may be formed in a flat shape. The mirror 1300 formed in a flat shape may be tilted at a predetermined angle toward the screen panel 1200 with the vertical axis as a reference. The screen panel 1200 may be formed in an inclined structure in which one end is arranged at an upper position than the other end on the vertical axis.

[0157] Reference Figures 6a to 8b The field of view (FoV), image size, and volume of the vehicle imaging device 1000 of the present specification may be as shown in Table 1. In this regard, low / mid / high may represent low / mid / high of the image size or may represent low / mid / high of the volume of the vehicle imaging device.

[0161] On the other hand, the image forming unit (PGU) of the vehicle imaging device of the present specification may be formed by a structure arranged in a horizontal direction on one side of the screen panel. Fig. 9 The structure of a vehicle imaging device is shown in which an image forming device is horizontally arranged on one side of a screen panel.

[0162] Reference Fig. 9 , the vehicle imaging device 1000 may include a cover 1010, an image forming device 1100, a screen panel 1200, a mirror 1300, and a second mirror 1320. The second mirror 1320 may be disposed in a side area of ​​an upper portion of the screen panel 1200. The image forming device 1100 may be disposed in a side area of ​​a lower portion of the screen panel 1200. The second mirror 1320 may be disposed at a distance farther from an end of the screen panel 1200 than the mirror 1300. Light output from the image forming device 1100 may be reflected from the mirror 1300 and the second mirror 1320. Referring to Figure 6a and Fig. 9 , the light reflected from the second mirror 1320 may be reflected again from the screen panel 1200 and incident on the specific area 251R of the windshield, so that an image may be displayed in the specific area 251R.

[0163] On the other hand, the resolution of the image provided by the vehicle imaging device can be set to 854x480, 1280x720 or 1920x1080, but is not limited thereto. An image with a resolution of 854x480 can be implemented by FWXGA (Full Wide Xtended Graphics Array). An image with a resolution of 1280x720 can be implemented by HD (High Density). An image with a resolution of 1920x1080 can be implemented by FHD (Full High Density).

[0164] On the other hand, in the vehicle imaging device of the present specification, the screen panel may be composed of a plurality of layers. Fig.10a The screen panel of the vehicle imaging device of this specification is composed of a plurality of layers. Figures 7a to 10a (a), in the reflective layer 1210 of the screen panel 1200, the plurality of patterns 1212 may be arranged separately. The plurality of patterns 1212 of the reflective layer 1210 may constitute a part of an ellipse formed in one axis and another axis direction. The plurality of patterns 1212 of the reflective layer 1210 may be arranged separately along another axis direction.

[0165] Reference Figures 7a to 10a (b), the screen panel 1200 may include a reflective layer 1210 and a diffusion layer 1220. The reflective layer 1210 is formed as a Fresnel structure, which may also be referred to as a Fresnel layer. The plurality of patterns formed in the reflective layer 1210 in another axial direction may be arranged spaced apart along one axial direction. The diffusion layer 1220 may be arranged on one side of the reflective layer 1210. The back side of the diffusion layer 1220 may be attached to one side of the reflective layer 1210.

[0166] Fig.10b This is a diagram showing the Fresnel structure of the reflective layer of the screen panel of this specification. Fig.10b (a) shows a cross-sectional view of the reflective layer 1210 of the screen panel. Fig.10b (a), the reflective layer 1210 of the screen panel may be formed to a specified depth Dp. The reflective layer 1210 may include a first pattern 1211 in the first region 1210-R1 and a second pattern 1212 in the second region 1210-R2. The first pattern 1211 may be formed as a metal pattern to reflect light. The second pattern 1212 may be formed as a metal pattern or a non-metal pattern.

[0167] Reference Figures 7a to 8b as well as Fig.10b, light incident from the mirror 1300 toward a desired direction can be reflected from the first pattern 1211. On the contrary, light incident from another undesired direction can be absorbed by the second pattern 1212 formed as a non-metallic pattern. Therefore, light incident from another undesired direction is not reflected from the reflective layer 1210 of the screen panel, thereby being able to improve the quality of an image displayed on the windshield.

[0168] In the first region 1210-R1, the reflective layer 1210 may be formed into a first pattern 1211 having a first slope angle. In the second region 1210-R2, the reflective layer 1210 may be formed into a second pattern 1212 having a second slope angle greater than the first slope angle. The reflective layer 1210 may be formed into a structure in which the first pattern 1211 of the first region 1210-R1 and the second pattern 1212 of the second region 1210-R2 are repeated. Figure 7a , Fig.10a as well as Fig.10b The plurality of patterns may be configured such that as a vertical distance from the screen panel 1200 to the cover 1010 gradually decreases, a separation distance between the plurality of patterns 1211 and 1212 of the reflective layer 1210 decreases.

[0169] The first pattern 1211 may be formed in a prescribed straight line or parabola shape.

[0170] Fig.10b (b) shows the elliptical structures of the upper and lower surfaces of the reflective layer 1210 of the screen panel and the second pattern 1212 on the side. Fig.10b (b), the first boundary region 1211b formed on the upper surface of the reflective layer 1210 may be referred to as a peak structure. The first boundary region 1211b may be formed as an elliptical structure. The first boundary region 1211b formed by the elliptical structure may be formed as a peak structure. p 2 x 2 +a p 2 y 2 -a p 2 b p 2 =0. In this regard, a p is the x value at y=0 of the peak, b p is the y value at x=0 of the peak. The third metal pattern 1213 formed on the lower surface may be referred to as a valley structure. The second boundary region 1212b may also be formed as an elliptical structure. The second boundary region 1212b formed by the elliptical structure may be formed as b v 2 x2 +a v 2 y 2 -a v 2 b v 2 =0. In this regard, a v is the x value at y=0 in the valley, b v is the y value at x=0 in the valley.

[0171] Reference Figures 6a to 10b , the reflective layer 1210 may be formed with a plurality of patterns 1211 to reflect the light formed in the image forming device 1100. The cross section of the plurality of patterns 1211 may be in the shape of a straight line or a parabola, and the front side may be formed in an elliptical shape. The diffusion layer 1220 may be disposed on one side of the reflective layer 1210, and the light reflected from the reflective layer 1210 may be diffused within a specified angle range based on the vertical direction of the cover 1010. As the vertical distance from the screen panel 1200 to the cover 1010 decreases, the lengths L1a, L1b, and L1c of the plurality of patterns 1211 of the reflective layer 1210 in one axis direction decrease to form the plurality of patterns 1211. As the vertical distance from the screen panel 1200 to the cover 1010 decreases, the first inclination angle of the plurality of patterns 1211 of the reflective layer 1210 increases.

[0172] The reflective layer 1210 may include a plurality of first patterns 1211 and a plurality of second patterns 1212. The plurality of first patterns 1211 may be formed in a straight line or parabola shape having a first inclination angle in cross section and an elliptical shape in front to reflect light. A plurality of second patterns 1212 may be arranged between the plurality of first patterns 1211. The plurality of second patterns 1212 may be formed in a straight line or parabola shape having a second inclination angle greater than the first inclination angle of the plurality of first patterns 1211. The length of the plurality of first patterns 1211 of the reflective layer 1210 of one side area of ​​the image forming device 1100 is formed to be longer than the length of the plurality of first patterns 1211 of the reflective layer 1210 of the other side area.

[0194] pass Fig.14a and Fig.14b The screen panel 1200 is offset to one side, so that a tall eye-box can be achieved. Fig.14a and Fig.14b By shifting the screen panel 1200 to the other side, a short eye-box can be achieved. Fig.14a and Fig.14b The screen panel 1200 is configured in a normal position to achieve a normal eye-box.

[0195] On the other hand, the reflective layer of the screen panel of the vehicle imaging device of the present specification can reflect the light forming the image and the sunlight. Fig.15a This diagram shows the structure in which the light that forms an image and sunlight are reflected from the screen panel and directed toward the user's field of view. Fig.15b This diagram shows the area formed by sunlight reflected according to the incident angle of the sun. Fig.15c This is a diagram showing an area formed by light that forms an image in the vehicle imaging device of this specification.

[0196] Reference Fig.15a , the light forming the image can be reflected from the mirror 1300 and the screen panel 1200 in the image forming unit (PGU) 1100, and reflected from the windshield of the vehicle through the cover 1010, thereby traveling toward the visual field of the user sitting in the front passenger seat. Thus, the user sitting in the front passenger seat can recognize the image reflected from a specific area of ​​the windshield of the vehicle. Thus, a personalized infotainment display for a vehicle can be realized.

[0197] The sunlight may be reflected from the screen panel 1100 through the windshield and cover 1010 of the vehicle, and the reflected sunlight may travel to a position higher than the user's field of view through the cover 1010. As the incident angle of the sunlight decreases, the sunlight may be reflected from the screen panel 1100 through the windshield and cover 1010 of the vehicle, and the reflected sunlight may travel from the end of the cover 1010 to the user's field of view.

[0198] The reflected sunlight can travel from the end of the cover 1010 to the user's field of view, referring to Figure 7a and Figure 7b , the end of the cover 1010 may be formed by an opaque area 1010a to block sunlight. Figure 7a , Figure 7b and Fig.15a As the incident angle of sunlight decreases, the sunlight may be reflected from the screen panel 1100 through the windshield and cover 1010 of the vehicle, and the reflected sunlight may be blocked in the opaque region 1010a. Thus, as the incident angle of sunlight decreases, the sunlight is reflected from the screen panel 1100 through the windshield and cover 1010 of the vehicle, and is blocked in the opaque region 1010a of the cover 1010. Therefore, the problem that it is difficult to recognize an image in a specific region of the windshield with the naked eye from the user's field of vision position due to an external light source such as sunlight can be solved.

[0199] Reference Figure 6a Figure 10 Fig.15a and Fig.15b , the light can be reflected by the reflective layer 1210 of the screen panel 1200, so that an image is displayed in a specific area 251R of the windshield of the passenger seat. In this regard, the reflected light can be formed in the field of vision of the user sitting in the passenger seat and outside the field of vision of the driver sitting in the driver's seat.

[0200] In this regard, due to Fig.15b The light reflected from the windshield of the vehicle represented by the dashed line is as follows: Figure 6a In that way, an image can be displayed in a specific area 251R of the windshield. Fig.15b By using the light reflected from the windshield of the vehicle indicated by the solid line, a panoramic view can be formed within the field of vision of the user sitting in the front passenger seat. Thus, the image displayed by the reflected light in the specific area 251R of the windshield of the front passenger seat is formed only in the field of vision of the user sitting in the front passenger seat. Therefore, the image displayed in the specific area 251R of the windshield of the front passenger seat is formed outside the field of vision of the driver sitting in the driver's seat, thereby improving driver safety.

[0201] Reference Figure 6a Figure 10 Figures 15a to 15c , the vehicle imaging device 1000 can be set in the passenger seat of the vehicle, and the vehicle imaging device 1000 can have a screen panel 1200. In this regard, the vehicle imaging device 1000 buried in the storage box of the passenger seat can be provided with a screen panel 1200. A personalized infotainment display can be realized by the vehicle imaging device buried in the storage box of the passenger seat. In addition, an additional vehicle imaging device can be buried in the storage box of the driver's seat. An additional screen panel 1200b can be provided in the vehicle imaging device set in the driver's seat. The image formed by the vehicle imaging device set in the driver's seat can be composed of a plurality of driving-related screens. The screen size composed of a plurality of driving-related screens can be realized by a widescreen display (wide display) having a large aspect ratio with a width greater than a specified ratio of a length.

[0202] Reference Figure 6a Figure 10 Figures 15a to 15c , the reflective layer 1210 of the screen panel 1200 of the vehicle imaging device can reflect the light that forms the image and reflect the sunlight. When the sun is incident at a first angle, the sunlight reflected by the reflective layer 1210 can be incident and reflected at a first angle from a first position Wp1 of the windshield with the horizontal axis as a reference. The sunlight reflected from the first position Wp1 of the windshield at an angle less than the critical angle can travel into the field of vision of the driver sitting in the driver's seat. Therefore, even if the sunlight reflected at an angle less than the critical angle travels into the field of vision of the driver, it does not hinder driving, and may help driving because it illuminates the surrounding environment.

[0203] When the sun is incident at a second angle greater than the first angle, the sunlight reflected by the reflective layer 1210 is incident at the second angle from the second position Wp2 of the windshield with reference to the horizontal axis. The sunlight incident at the second angle from the second position of the windshield can pass through the windshield or be reflected from the second position Wp2 and travel to the area between the driver and the passenger seat. Therefore, the sunlight reflected at an angle greater than the critical angle does not travel to the driver's field of vision, thereby preventing obstruction to driving.

[0204] The personalized infotainment device for a vehicle of the present specification has been described above. The technical effects of the personalized infotainment device for a vehicle of the present specification can be summarized as follows, but are not limited thereto.

[0205] The technical features of the personalized infotainment device for a vehicle of this specification can be summarized as follows.

[0206] According to the present specification, a large-screen infotainment image is realized through the windshield by using a structure that is embedded rather than protruding from the passenger seat, thereby providing a large-screen image device for the passenger seat of a vehicle.

[0207] In addition, according to the present specification, the virtual image optical system is used to remove elements that may hinder driving and can only be recognized by the passenger in the front passenger seat, thereby promoting safe driving by the driver.

[0208] In addition, according to the present specification, by using an Ultra Short Throw (UST) projection device and a special screen, a personalized infotainment display can be realized in a limited space inside a vehicle with a thin and small volume.

[0209] In addition, according to the present specification, a personalized infotainment device for a vehicle can be provided without using a glove box, an air bag, an air conditioning component, etc. inside a dashboard of a passenger seat of a vehicle.

[0210] The effects of the present specification are not limited to the effects mentioned above, and those skilled in the art can clearly understand other effects not mentioned through the description of the claims.

[0211] The present invention described above can be implemented by a computer-readable code in a medium storing a program.
