Abstract
Description
Technical Field
[0001] This application relates to the field of automotive intelligent electronics, and in particular to a head-up display device and a vehicle. Background Technology
[0002] A rearview mirror is an important device used to reflect the situation behind, to the side, and below a car, thereby ensuring safe driving. Through the rearview mirror, the driver can constantly observe the driving conditions and road conditions outside the vehicle, thus reducing the possibility of danger.
[0003] The existing rearview mirrors are mainly divided into traditional rearview mirrors and electronic rearview mirrors. Compared with traditional rearview mirrors, electronic rearview mirrors solve the problem of blind spots in the field of vision caused by the limitations of traditional rearview mirrors due to factors such as mirror curvature, size, and angle. They capture images through cameras and monitors and then display them in real time on the in-vehicle display, providing the driver with a better rear view. This method not only has a wider field of view, but also clearer images.
[0004] Currently, the displays used to show images from electronic rearview mirrors in vehicles are typically located in the same position as the mirrors within the driver's cabin. However, this setup still requires drivers to frequently turn their heads to see the images from the electronic rearview mirrors during normal driving, making it difficult for them to focus on the road ahead and consequently reducing driving safety.

[0019] Optionally, the first reflector is located between the two third reflectors, and the two opposite sides of the first reflector are respectively connected to one side of the two third reflectors.
[0020] Optionally, the reflecting surfaces of the two third mirrors in the two second reflecting groups are arranged to intersect, and the reflecting surface of each third mirror is arranged to intersect with the reflecting surface of the first mirror;

[0039] Augmented Reality-Head-Up Display (AR-HUD) is an automotive vision-assisted safety driving system. This system projects important information needed by the driver onto the windshield of the car through the optical path of the AR-HUD, integrating the displayed information with the surrounding real scene, so that the driver can directly obtain real-time road condition information and vehicle-related information on the windshield.
[0040] Existing vehicles are often equipped with AR-HUDs and paired electronic rearview mirrors. To facilitate wiring connections and driver habits, the electronic rearview mirrors typically have two internal displays positioned opposite each other on the inside of the door. However, this arrangement requires the driver to not only look down but also turn their head left and right to see the content displayed on the internal displays. This is extremely detrimental to driving safety, especially for vehicles equipped with AR-HUDs. When looking down or turning their head left and right, drivers can easily miss the AR-HUD displays and actual road conditions, leading to driving hazards.
[0041] Based on this, this application proposes a head-up display device that can directly project the content captured by the electronic rearview mirror onto the windshield, making the driver's vision clearer while driving. At the same time, the driver can observe the information in the rearview mirror without having to turn their head left or right or look down, allowing the driver to focus their attention more, increasing the safety factor while driving, and reducing the probability of the driver causing dangerous accidents while driving.
[0042] This application provides a head-up display device, which can be an AR-HUD. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the structure of a head-up display device provided in this application. The head-up display device 00 can be installed in the cockpit of a vehicle, and the head-up display device 00 may include: a first display module 10, a second display module 20, and a reflector group 30.
[0043] The first display module 10 in the head-up display device 00 is used to collect image information for vehicle-assisted driving and, based on the image information, emits a first beam of light to the reflector group 30. Here, the image information for vehicle-assisted driving may include: vehicle speed information, road information acquired during vehicle operation, and vehicle-related assisted driving information such as remaining fuel or battery power. The specific settings for the assisted driving image information can be configured according to actual usage requirements, and this application does not impose any restrictions on this.
[0044] For example, the vehicle's control system can generate vehicle-related driver assistance image information, and the vehicle's control system can send this driver assistance image information to the first display module 10 in the head-up display device 00, so that the first display module 10 can acquire this driver assistance image information. In this case, please refer to... Figure 2 , Figure 2 This is an optical path diagram of a first beam provided in an embodiment of this application. The first display module 10 can emit the first beam to the reflector group 30 based on the acquired image information of assisted driving. Here, the first beam is an image beam containing images of assisted driving.
[0045] The second display module 20 in the head-up display device 00 is used to acquire rearview mirror image information collected by the vehicle's electronic rearview mirror, and to emit a second beam of light to the reflector group 30 based on the rearview mirror image information. Here, the rearview mirror image information includes real-time road condition information, external driving information, and visual image information collected by other electronic exterior rearview mirrors. The specific settings of the visual image information can be configured according to actual usage requirements, and this application does not impose any restrictions on this.
[0046] For example, the electronic rearview mirror in the vehicle can collect rearview mirror image information, and the rearview mirror image information collected by the electronic rearview mirror can be directly sent to the second display module 20 in the head-up display device 00, or the rearview mirror image information can be forwarded to the second display module 20 in the head-up display device 00 through the vehicle's control system, so that the second display module 20 can obtain this rearview mirror image information. In this case, please refer to Figure 3 , Figure 3 This is an optical path diagram of a second beam provided in an embodiment of this application. The second display module 10 can emit a second beam to the reflector group 30 based on the acquired rearview mirror image information. Here, the second beam is an image beam containing rearview mirror image information.
[0047] The reflector group 30 in the head-up display device 00 is used to project the first beam and the second beam onto the windshield 01 of the vehicle.
[0048] The first virtual image projected onto the windshield 01 by the first beam does not overlap with the second virtual image projected onto the windshield 01 by the second beam. Thus, while driving, the driver can simultaneously view both the first and second virtual images on the windshield 40. The driver can obtain vehicle-related driver assistance information through the first virtual image and the rearview mirror image captured by the electronic rearview mirror through the second virtual image.
[0049] In summary, the head-up display device provided in this application includes a first display module, a second display module, and a reflector group. The first display module converts vehicle-related assisted driving image information into a first light beam, and the second display module converts rearview image information collected by the electronic rearview mirror into a second light beam. The reflector group projects the first and second light beams onto the vehicle's windshield. This allows the driver to simultaneously view both a first virtual image projected by the first light beam and a second virtual image projected by the second light beam on the windshield while driving. The driver can obtain vehicle-related assisted driving images through the first virtual image and the rearview mirror image collected by the electronic rearview mirror through the second virtual image. Thus, the driver can observe the rearview mirror image without significant left or right head movements while driving, allowing for greater focus and increasing driving safety, thereby effectively reducing the probability of dangerous accidents.
[0050] In this embodiment, the vehicle has two electronic rearview mirrors: one mounted on the left side and one mounted on the right side. The left-side mirror captures an image of the vehicle's left rear, while the right-side mirror captures an image of the vehicle's right rear.
[0051] Correspondingly, such as Figure 1 and Figure 2 As shown, the head-up display device 00 also has two second display modules 20, and each of the two second display modules 20 corresponds one-to-one with the two electronic rearview mirrors. Each second display module 20 is used to acquire the rearview mirror image information collected by the corresponding electronic rearview mirror and emit a corresponding second beam to the reflector group 30, so that the two second virtual image images formed by the two second beams projected on the windshield 01 do not overlap. The first display module 10 can be located between the two second display modules 20.
[0052] In this configuration, while driving, the driver can simultaneously view two second virtual images on the windshield 40. One second virtual image shows the left rear of the vehicle, and the other shows the right rear. Thus, the head-up display 00 provides a more realistic view of the vehicle's condition, further reducing the likelihood of accidents caused by a lack of road awareness.
[0053] It should be noted that by placing the first display module 10 between the two second display modules 20, the compactness of the distribution of various components in the head-up display device 00 can be improved, thereby reducing the size of the head-up display device 00 and making the head-up display device 00 occupy less space in the cockpit.
[0054] In this embodiment, the first display module 10 and the two second display modules 20 can each be three independent displays. In other possible implementations, the first display module 10 and the second display modules 20 can also be integrated into a single display, that is, the first display module 10 and the second display module 20 are the same display. It is understood that this display can include a first display area and two second display areas located on either side of the first display area. The first display area is used to emit a first beam containing assisted driving information, and the second display areas are used to emit a second beam containing virtual image information. Therefore, the portion of this display containing the first display area is the first display module, and the portion containing the second display areas is the second display module.
[0055] It should be noted that, compared to setting up two displays, integrating the first display module 10 and the second display module 20 into a single display setup can further improve the compactness of the internal component arrangement of the head-up display device 00, thereby reducing the size of the head-up display device 00. This allows the head-up display device 00 to be placed in a compact cockpit, reducing the possibility of affecting the driver's normal driving operations.
[0056] Optionally, please refer to Figure 4 , Figure 4 This is a schematic diagram of the planar structure of a windshield provided in this application. The windshield 01 includes a first observation surface facing the cockpit side. The first observation surface includes a first region A1 and two second regions A2. The first region A1 is used to receive a first beam of light to form a first virtual image. The two second regions A2 correspond one-to-one with two second beams of light. Each second region A2 is used to receive the corresponding second beam of light to form a corresponding second virtual image. The first region A1 is located between the two second regions A2.
[0057] For example, the two second regions A2 can be located on either side of the first region A1, so that... Figure 3Taking the windshield 01 shown as an example, the two second areas A2 can be located on the upper and lower sides of the first area A1, respectively. In one embodiment of this application, the virtual image information collected by the rearview mirror on the left side of the vehicle can be projected onto the second area A2 above the first area A1 through a second beam of light, and the virtual image information collected by the rearview mirror on the right side of the vehicle can be projected onto the second area A2 below the first area A1 through another second beam of light. The specific settings can be configured according to actual usage needs; it is sufficient that the driver can distinguish between the two rearview mirrors in different positions.
[0058] In other possible implementations, the second region A2 can be located on the left and right sides of the first region A1, in other words, as... Figure 4 As shown, the virtual image information collected by the rearview mirror on the left side of the vehicle can be projected through a second beam to the second area A2 located to the left of the first area A1, and the virtual image information collected by the rearview mirror on the right side of the vehicle can be projected through another second beam to the second area A2 located to the right of the first area A1. This conforms to the driver's driving habits, thereby distinguishing and observing the images displayed by different rearview mirrors in a timely manner, thus reducing the possibility of driving dangers caused by the driver's inability to distinguish the corresponding rearview mirrors.
[0059] Please refer to it again. Figure 4 Optionally, the outer contour of the windshield includes a first side S1 and a second side S2 arranged opposite to each other, and a third side S3 and a fourth side S4 arranged opposite to each other. Both the third side S3 and the fourth side S4 are located between the first side S1 and the second side S2, with the first side S1 being closer to the top of the vehicle than the second side S2. One of the two second regions A2 is located in the corner area formed between the first side S1 and the third side S3, and the other second region A2 is located in the corner area formed between the first side S1 and the fourth side S4. This design, on the one hand, reduces the need for the driver to look down while driving by placing the second regions A2 on either side of the first region A1, and on the other hand, allows the driver to use their peripheral vision to observe the image displayed in the rearview mirror, which is more in line with the driver's driving habits.
[0060] It should be noted that, in one embodiment of this application, since the first display module 10 is located between the two second display modules 20, by setting the two second regions A2 in the two corner regions near the top of the vehicle, on the one hand, the complexity of the optical path can be reduced, thereby reducing the possibility of different beams interfering with each other. On the other hand, the arrangement of the reflector group 30 can be made more compact, thereby reducing the size of the head-up display device. By setting the two second regions A2 in the two corner regions near the top of the vehicle, the possibility of the driver looking down while driving is reduced, which helps to improve the driver's driving safety.
[0061] Please see Figure 5 , Figure 5 This is a schematic diagram of a mirror assembly provided in this application. The mirror assembly 30 may include: a first reflection group 310 and two second reflection groups 320. Please refer to... Figure 6 , Figure 6 This is another optical path diagram of the first beam provided in an embodiment of this application. The first reflection group 310 in the reflector group 30 is used to project the first beam onto the first region A1. Please refer to... Figure 7 , Figure 7 This is another optical path diagram of the second beam provided in the embodiment of this application. The two second reflection groups 320 correspond one-to-one with the two second regions A2. Each second reflection group 320 is used to project the corresponding second beam onto the corresponding second region A2.
[0062] It should be noted that by setting two second reflection groups 320 and one first reflection group 310, it can be ensured that the first beam and the second beam are accurately projected into the corresponding areas. Compared with setting only one reflector group, setting two reflector groups can reduce the complexity of the optical path and reduce the possibility of mutual interference between beams.
[0063] Optionally, such as Figures 5 to 7 As shown, the first reflective group 310 in the reflector group 30 includes a first reflector 3110 and a second reflector 3120 disposed opposite to each other. The reflective surface of the first reflector 3110 faces both the light-emitting side of the first display module 10 and the reflective surface of the second reflector 3120. The reflective surface of the second reflector 3120 faces the first region A1. Each second reflective group 320 in the reflector group 30 includes a third reflector 3210 and a fourth reflector 3220 disposed opposite to each other. The reflective surface of the third reflector 3210 faces both the light-emitting side of the corresponding second display module 20 and the reflective surface of the fourth reflector 3220. The reflective surface of the fourth reflector 3220 faces the first region A1 of the corresponding second reflective group 320.
[0064] For example, please refer to again Figure 6 and Figure 7 For ease of understanding, Figure 6 and Figure 7 The first region A1 and the second region A2 in the windshield 01 are represented by dashed boxes. In some embodiments, the first region A1 and the second region A2 are defined by rectangular frames. This is only for ease of understanding and does not represent the actual situation of the first region A1 and the second region A2. In fact, the shape and size of the first region A1 and the second region A2 are not fixed and can be set according to the actual use. This application will not elaborate on this.
[0065] For example, please refer to again Figure 6 The light path of the first beam is represented by a dotted line with a direction. After the first beam is emitted by the first display module 10, it is first reflected by the reflective surface of the first reflector 3110 to the reflective surface of the second reflector 3120, and then reflected by the reflective surface of the second reflector 3120 to the first area A1 set on the windshield 01, thereby completing the virtual image display of the conventional AR-HUD display module.
[0066] Please refer to it again. Figure 7 , Figure 7 The directional dotted line in the image represents the optical path of the second beam. After being emitted by the second display module 20, the second beam is first reflected by the reflective surface of the third reflector 3210 to the reflective surface of the fourth reflector 3220, and then reflected by the reflective surface of the fourth reflector 3220 to the first area A1 set on the windshield 01, thus completing the virtual image display part of the electronic rearview mirror. Figure 6 The optical path diagram of the second beam emitted by the second display module 20 on the right side is quite similar, and will not be described in detail here.
[0067] It should be noted that the above-mentioned first reflection group 310 and second reflection group 320 can accurately project the light beams emitted by the first display module 10 and the second display module 20 onto the corresponding area of the windshield 01, thereby reducing the possibility of overlap between the virtual images formed by the first light beam and the second light beam on the windshield 01.
[0068] Please refer to it again. Figure 5 Optionally, the first reflector 3110 is located between the two third reflectors 3210, and the opposite sides of the first reflector 3110 are respectively connected to one side of the two third reflectors 3210. It should be noted that by connecting the two sides of the second reflector 3120 to the third reflectors 3210 respectively, the reflector assembly 30 is arranged more compactly, thereby reducing the size of the head-up display device 00 and helping to reduce situations where it is difficult to install the head-up display device 00 due to limited cockpit space.
[0069] Please refer to it again. Figure 5 Optionally, the reflecting surfaces of the two third reflectors 3210 in the two second reflector groups 320 are arranged to intersect, and the reflecting surface of each third reflector 3210 is arranged to intersect with the reflecting surface of the first reflector 3110, wherein the two fourth reflectors 3220 in the two second reflector groups 320 are arranged separately from the first reflector 3110.
[0070] In one embodiment of this application, it can be as follows Figure 5 As shown, the first reflector 3110 is arranged parallel to the windshield 01, while the fourth reflector 3220 is not arranged parallel to the windshield 01. This allows the second beam to be accurately projected onto the two upper corners of the windshield 01. It is understood that this embodiment only shows one achievable embodiment, and the actual configuration can be adjusted according to the usage. It is only necessary to ensure that the second beam can be accurately projected onto the corresponding area of the windshield 01. This application will not elaborate on this.
[0071] It should be noted that by separating the two fourth reflectors 3220 and the first reflector 3110, and then setting the third reflector 3210 and the first reflector 3110 to intersect, the accuracy of the reflector group 30 during reflection is increased, and the possibility of overlap between the virtual images formed by the first beam and the second beam on the windshield 01 is reduced.
[0072] In summary, the head-up display device provided in this application includes a first display module, a second display module, and a reflector group. The first display module converts vehicle-related assisted driving image information into a first light beam, and the second display module converts rearview image information collected by the electronic rearview mirror into a second light beam. The reflector group projects the first and second light beams onto the vehicle's windshield. This allows the driver to simultaneously view both a first virtual image projected by the first light beam and a second virtual image projected by the second light beam on the windshield while driving. The driver can obtain vehicle-related assisted driving images through the first virtual image and the rearview mirror image collected by the electronic rearview mirror through the second virtual image. Thus, the driver can observe the rearview mirror image without significant left or right head movements while driving, allowing for greater focus and increasing driving safety, thereby effectively reducing the probability of dangerous accidents.
[0073] This application also provides a vehicle, including a cockpit and a head-up display device 00 installed in the cockpit. The vehicle includes commercial vehicles, electric vehicles, and other intelligent vehicles equipped with electronic rearview mirrors.
[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
