Description

Technical Field

[0001] This invention relates to an integrated head-up display device that can integrate a panoramic head-up display device and a windshield head-up display device together. Background Technology

[0002] With the development of related technologies, the application of head-up displays (HUDs) in vehicles has gradually become more widespread. Common HUDs include panoramic HUDs (P-HUDs) and windshield HUDs (W-HUDs).

[0003] A panoramic head-up display (P-HUD) projects an image onto a black silkscreened area below the windshield in front of the driver. For P-HUDs, the projection area is relatively small and its position is relatively fixed, resulting in a limited amount of information that can be projected. However, because the projection area is black, the image projected by a P-HUD has high contrast, making it less likely for the driver to miss the information projected. Based on these characteristics, P-HUDs are suitable for projecting information that is highly relevant to vehicle driving and requires a small display area.

[0004] A windshield head-up display (W-HUD) projects an image onto a transparent glass area in the upper part of the windshield in front of the driver. W-HUDs offer a relatively large projection area and flexible positioning, allowing for the projection of a significant amount of information. However, due to the transparent glass surface, the image contrast is relatively low, making it susceptible to ambient light fluctuations, potentially causing the driver to miss information projected by the W-HUD. Based on these characteristics, W-HUDs are best suited for projecting information that is less relevant to driving and requires a large display area.

[0005] In other words, P-HUD and W-HUD are suitable for projecting different types of information. However, according to existing technology, installing both P-HUD and W-HUD in a vehicle would result in a large space requirement and high cost.

[0006] Therefore, there is a need to propose a head-up display device that can simultaneously realize the functions of P-HUD and W-HUD, and has a compact structure and low cost.

[0007] The information contained in the background section of this invention is only intended to enhance the understanding of the general background of this invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

Figure 2 To illustrate another perspective view of an integrated head-up display device according to an exemplary embodiment of the present invention, Figure 3 To illustrate yet another perspective view of an integrated head-up display device according to an exemplary embodiment of the present invention, Figure 4 This is a schematic diagram illustrating the display effect of an integrated head-up display device according to an exemplary embodiment of the present invention. Figure 5 A perspective view of the housing of an integrated head-up display device according to an exemplary embodiment of the present invention is shown. Figure 6 This diagram illustrates the configuration of an integrated head-up display device according to an exemplary embodiment of the present invention.

[0034] Figures 1 to 3 A perspective view of an integrated head-up display device according to an exemplary embodiment of the present invention is shown.

[0035] like Figures 1 to 3 As shown, an integrated head-up display device according to an exemplary embodiment of the present invention may include: a display 10, a first reflector 20, a second reflector 30, and a third reflector 40.

[0036] In an exemplary embodiment, the display 10 may be a display device for projecting images. As an example, the display 10 may include: a thin-film transistor (TFT) display, a liquid crystal display (LCD), a digital light processing (DLP) display, a liquid crystal on silicon (LCOS) display, etc. The display 10 may include: a first display area 11 and a second display area 12, wherein the first display area 11 may be used to project a first image, and the second display area 12 may be used to project a second image different from the first image.

[0037] The first display area 11 can be positioned in front of the second display area 12. Here, the front-rear direction refers to the front-rear direction relative to the vehicle. That is, the first display area 11 can be closer to the windshield, and the second display area 12 can be closer to the driver.

[0038] The display 10 can be tilted toward the windshield. Specifically, the display 10 can be set at a first predetermined angle relative to the vertical direction (i.e., the angle between the display plane of the display 10 and the vertical direction can be the first predetermined angle) so that the first image projected from the first display area 11 of the display 10 can be directly incident on the windshield 50.

[0039] Here, the vertical direction refers to the height direction of the vehicle. Preferably, the first predetermined angle can be in the range of approximately 60° to 70°.

[0040] The first reflector 20 can be a plane reflector. The first reflector 20 can be disposed between the first display area 11 and the second display area 12 of the display 10. The first reflector 20 can be tilted towards the second display area 12. Specifically, the first reflector 20 can be disposed relative to the display 10 at a second predetermined angle (i.e., the angle between the plane containing the first reflector 20 and the vertical direction can be a second predetermined angle), so that the second image projected from the second display area 12 of the display 10 can be incident on the first reflector 20 and reflected by the second reflector 30. For example, the second predetermined angle can be in the range of approximately 55° to 65°.

[0041] The second reflector 30 can be a plane reflector. The second reflector 30 can be positioned behind the second display area 12. The second reflector 30 can be tilted towards the second display area 12. Specifically, the second reflector 30 can be positioned at a third predetermined angle relative to the vertical direction, so that the second image reflected by the first reflector 20 can be incident on the second reflector 30 and reflected by the third reflector 40. For example, the third predetermined angle can be in the range of approximately 2° to 8° (i.e., the angle between the plane containing the third reflector 40 and the vertical direction can be the third predetermined angle).

[0042] The third reflecting mirror 40 can be a curved reflecting mirror. As an example, the third reflecting mirror 40 can be a freeform reflecting mirror. The third reflecting mirror 40 can be positioned between the first reflecting mirror 20 and the second reflecting mirror 30, and at a position lower than the first reflecting mirror 20 and the second reflecting mirror 30. The third reflecting mirror 40 can be tilted towards the second reflecting mirror 30. Specifically, the third reflecting mirror 40 can be configured such that the second image reflected by the second reflecting mirror 30 can be incident on the third reflecting mirror 40 and reflected towards the second projection area 52.

[0043] Furthermore, the third reflecting mirror 40 may have a predetermined magnification so that the second image reflected by the third reflecting mirror 40 can be magnified by a predetermined factor. For example, the predetermined factor may be approximately 2 to 6 times.

[0044] Furthermore, the integrated head-up display device according to an exemplary embodiment of the present invention may include, for example: Figure 4 The windshield 50 shown can be the front windshield of a vehicle. The windshield 50 may include a first projection area 51 and a second projection area 52.

[0045] The first projection area 51 can be a black silkscreen area. The first image projected from the first display area 11 can be directly incident on the first projection area 51. Thus, the same display effect as a P-HUD can be achieved through the first display area 11 and the first projection area 51.

[0046] The second projection area 52 can be a portion of the windshield 50 located above the first projection area 51. The second image reflected by the third reflector 40 can be incident on the second projection area 52. Thus, the same display effect as a W-HUD can be achieved through the second display area 12, the first reflector 20, the second reflector 30, the third reflector 40, and the second projection area 52.

[0047] Since the first image is directly projected onto the first projection area 51 of the windshield 50, while the second image is magnified by the third reflector 40 and projected onto the second projection area 52 of the windshield 50, the area of ​​the first display area 11 used to display the first image can be larger than the area of ​​the second display area 12 used to display the second image.

[0048] The first image projected onto the first projection area 51 may include first information related to vehicle driving. The second image projected onto the second projection area 52 may include second information related to vehicle driving. The first information may be of higher importance than the second information.

[0049] Since the first projection area 51 is a black silkscreen area, the first image is less affected by the brightness of the external environment and has a high contrast. Therefore, the first image can be used to display first information of high importance. Conversely, since the second projection area 52 is transparent glass, the second image may be easily affected by the brightness of the external environment and has a low contrast. Therefore, the second image can be used to display second information of lower importance.

[0050] As an example, the first information may include: vehicle instrument information (e.g., information related to vehicle speed, engine speed, electric motor speed, driving range, remaining fuel, malfunction indicator lights, status indicator lights, etc.), notification information related to autonomous driving (e.g., information related to emergency notifications for dangerous situations, Highway Driving Assist (HDA) warning indicators, Lane Departure Warning (LDW) indicators, Lane Keeping Assist (LKA) warning indicators, etc.), and notification information related to the autonomous driving setting status (e.g., messages related to autonomous driving assistance function preparation prompts, automatic steering assistance prompts, following distance prompts, driving status prompts, autonomous driving following distance, etc.).

[0051] As an example, the second information may include information that needs to be combined with real road conditions, such as navigation information, road information ahead, distance to the vehicle in front, pedestrian notification, lane keeping assist notification, forward collision warning, etc.

[0052] In addition, such as Figure 3 As shown, the integrated head-up display device according to an exemplary embodiment of the present invention may further include an axis 41 and a drive device 42.

[0053] Shaft 41 can be disposed on the third reflector 40. As an example, shaft 41 can be disposed in the middle of the third reflector 40 so that the third reflector 40 can rotate about shaft 41.

[0054] The drive unit 42 can be connected to the shaft 41 to rotate the shaft 41. As an example, the drive unit 42 can be a motor. When the drive unit 42 is running, it rotates the shaft 41, causing the third reflector 40 to rotate about the shaft 41. This allows the position of the second image reflected by the third reflector 40 incident on the second projection area 52 to be changed.

[0055] In addition, such as Figure 2 , Figure 5 and Figure 6 As shown, the integrated head-up display device according to an exemplary embodiment of the present invention may further include: a first light source 61, a second light source 62, a first heat sink 63, and a second heat sink 64.

[0056] Since the first display area 11 and the second display area 12 of the display 10 are used to display different images, light sources can be provided for the first display area 11 and the second display area 12 respectively. The first light source 61 can be located below the first display area 11 of the display 10. The first light source 61 can be used to illuminate the first display area 11 of the display 10. The second light source 62 can be located below the second display area 12 of the display 10. The second light source 62 can be used to illuminate the second display area 12 of the display 10.

[0057] Since the second image is more susceptible to the brightness of the external environment than the first image, the brightness of the second light source 62 used for the second image can be set to be higher than the brightness of the first light source 61 used for the first image.

[0058] As an example, the first light source 61 and the second light source 62 can be light-emitting diodes (LEDs). To ensure the luminous efficiency of the light sources, heat sinks can be provided for the first light source 61 and the second light source 62 respectively. The first heat sink 63 can be located below the first light source 61. The first heat sink 63 can be used to dissipate heat from the first light source 61. The second heat sink 64 can be located below the second light source 62. The second heat sink 64 can be used to dissipate heat from the second light source 62.

[0059] Furthermore, the integrated head-up display device according to an exemplary embodiment of the present invention may further include a housing 70. The housing 70 may have an internal space for accommodating the display 10, the first reflector 20, the second reflector 30, the third reflector 40, the first light source 61, and the second light source 62. A first heat sink 63 and a second heat sink 64 may be disposed outside the housing 70 and attached to the housing 70.

[0060] The housing 70 may include a first window 71 and a second window 72. A first image projected from the first display area 11 of the display 10 can exit through the first window 71. A second image projected from the second display area 12 of the display 10 can exit through the second window 72. Since the projection area of ​​the second image (second projection area 52) is higher than the projection area of ​​the first image (first projection area 51), the first window 71 and the second window 72 may have a height difference, and the second window 72 may be positioned higher than the first window 71.

[0061] In addition, such as Figure 6 As shown, the integrated head-up display device according to an exemplary embodiment of the present invention may further include a controller 80. The controller 80 may be configured to control a first display area 11 and a second display area 12 of the display 10 to display a first image and a second image. Furthermore, the controller 80 may be configured to control a first light source 61 and a second light source 62 to illuminate the first display area 11 and the second display area 12.

[0062] In addition, the controller 80 can be configured to adjust the projection position of the first image on the first projection area 51 and adjust the projection position (especially the projection height) of the second image on the second projection area 52.

[0063] Because drivers have different heights and builds, the projection positions of the first and second images are also different for each driver. Therefore, the projection positions of the first and second images are adjustable.

[0064] The controller 80 can be configured to adjust the projection position of the first image on the first projection area 51 of the windshield 50 by adjusting the position of the first image on the first display area 11 of the display 10. Furthermore, the controller 80 can be configured to control the drive unit 42 to rotate the shaft 41, thereby adjusting the projection position of the second image on the second projection area 52 of the windshield 50. For vehicles with seat memory function (IMF), the controller 80 can record the projection positions of the first and second images corresponding to each driver.

[0065] Specifically, since the first image is directly projected onto the first projection area 51 of the windshield 50, the projection position of the first image on the first projection area 51 of the windshield 50 (e.g., vertical and horizontal position) can be adjusted by adjusting the position of the first image on the first display area 11 of the display 10.

[0066] However, for the second image, since the area of ​​the second display area 12 used to display the second image is small, the margin available for adjusting the position of the second image on the second display area 12 of the display 10 is not large. More importantly, since the second image is projected onto the second projection area 52 of the windshield 50 only after multiple reflections by multiple mirrors (especially the reflection by the third mirror 40, which is a curved mirror), even a slight adjustment to the position of the second image on the second display area 12 of the display 10 may have a significant impact on the projection position of the second image on the second projection area 52 of the windshield 50, and may even cause image distortion.

[0067] Therefore, for the second image, the projection position of the second image on the second projection area 52 of the windshield 50 is mainly adjusted by changing the angle of the third reflector 40. Specifically, the controller 80 can be configured to control the drive device 42 to rotate the shaft 41, thereby rotating the third reflector 40 around the shaft 41, and thus changing the angle of the third reflector 40 relative to the second projection area 52. This adjusts the projection position (e.g., vertical position) of the second image on the second projection area 52 of the windshield 50.

[0068] Figure 7 This diagram illustrates the optical path of an integrated head-up display device according to an exemplary embodiment of the present invention. Point E may represent the position of the driver's eyes, the first position M1 may represent the position of the virtual image ultimately formed by the first image, and the second position M2 may represent the position of the virtual image ultimately formed by the second image.

[0069] like Figure 7 As shown, the first beam B1 of the first image projected from the first display area 11 of the display 10 can directly enter the first projection area 51 of the windshield 50 in a forward and upward direction. From the driver's perspective, the virtual image of the projected first image is formed at a first position M1 in front of the windshield 50.

[0070] The second beam B2 projected from the second display area 12 of the display 10 onto the first reflector 20 positioned between the first display area 11 and the second display area 12, can be incident forward and upward, and reflected by the first reflector 20. The second beam B2 reflected by the first reflector 20 can be incident backward and upward onto the second reflector 30 positioned above and behind the first reflector 20, and reflected by the second reflector 30. The second beam B2 reflected by the second reflector 30 can be incident forward and downward onto the third reflector 40 positioned between the first reflector 20 and the second reflector 30. The second beam B2 can be magnified by the third reflector 40 by a predetermined factor while being reflected by the third reflector 40. The magnified second beam B2 can be incident forward and upward onto the second projection area 52 of the windshield 50. From the driver's perspective, the virtual image of the projected second image is formed at a second position M2 in front of the windshield 50.

[0071] The existing P-HUD and W-HUD are set up separately. The P-HUD includes a display for showing images, and the W-HUD also includes a display for showing images. This configuration not only takes up a lot of space, but also increases the cost due to the use of two displays.

[0072] The integrated head-up display device according to an exemplary embodiment of the present invention can integrate P-HUD and W-HUD together, thereby realizing the functions of P-HUD and W-HUD, and has a compact structure and low cost.

[0073] The foregoing description of specific exemplary embodiments of the invention is for illustrative and descriptive purposes. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed, and it will be apparent that many modifications and variations can be made in light of the foregoing teachings.
