[0003] In the related art, the head-up display uses a reflector to reflect the image onto the windshield, or directly reflects the image onto the windshield, which has two problems: 1. As the size of the head-up display becomes larger and larger, the size of the imaging area of ​​the reflector and the windshield will also increase accordingly, and the process difficulty and cost of the reflector and the windshield will also increase; 2. The traditional head-up display uses curved mirrors and windshield reflection to magnify the virtual image, which will produce ghosting, and it is necessary to add a PVB wedge film to eliminate the ghosting, which will increase the difficulty of designing the optical path of the windshield and the head-up display.

[0039] The following illustrates some application scenarios of the present application.

[0040] Application scenario 1: Urban driving assistance. On busy city streets, drivers need to frequently pay attention to traffic lights, road signs and other vehicle dynamics. Using this vehicle-mounted head-up display device, important information such as navigation instructions and speed limits can be displayed directly in the driver's field of vision, thereby reducing the time the driver has to look down at the dashboard and improving driving safety.

[0041] Application scenario 2: Highway driving. On the highway, the driver needs to stay focused for a long time. At this time, the head-up display device can display information such as vehicle speed, lane departure warning, and front obstacle warning to help the driver better maintain a safe driving state.

[0042] Application scenario three: Driving in adverse weather conditions. In adverse weather conditions such as rain, snow, fog, etc., visibility is poor. At this time, the vehicle head-up display device can display information such as road conditions and visibility prompts to help drivers make safer driving decisions.

[0043] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0044] Figure 1 A schematic diagram of a vehicle-mounted head-up display device of the present application is shown.

[0045] In this application, if Figure 1 As shown, the vehicle-mounted head-up display device includes a windshield 006 and an image source component 001. The windshield 006 includes a waveguide layer 002. The waveguide layer 002 is provided with a first reflection texture 0021 and a second reflection texture 0022.

[0046] In the present application, the image source component 001 is used to generate a projection light beam of a picture to be displayed, and to project the projection light beam to the first reflection texture 0021, so that the projection light beam is incident on the waveguide layer 002 based on the first reflection texture 0021, and is fully reflected and propagated in the waveguide layer 002.

[0047] On this basis, the second reflection texture 0022 is used to emit the projection light beam that is fully reflected and propagated in the waveguide layer 002, and the emission direction is the direction of the driving position 005.

[0048] In this application, the windshield 006 is one of the core components of the vehicle head-up display device, responsible for guiding the light from the image source component 001 to the driver's field of vision, so that the driver can view the vehicle information without diverting his or her sight. Among them, the waveguide layer 002 is the core part of the windshield 006, which allows the light to be fully reflected and propagated inside through a specific design, and finally emitted from a preset position.

[0049] In the present application, the first reflection texture 0021 is a microstructure disposed on the waveguide layer 002, and is used to reflect the light beam emitted by the image source component 001 and guide it into the waveguide layer 002. The second reflection texture 0022 is another group of microstructures also disposed on the waveguide layer 002, and is used to reflect the light beam propagated by total reflection out of the waveguide layer 002, so that it is emitted toward the driver.

[0050] In the present application, the windshield 006 further includes a first protective layer 004 and a second protective layer 003 .

[0051] For example, the wind plate is a stacked design consisting of a first protective layer 004 , a waveguide sheet layer 002 , and a second protective layer 003 .

[0052] The first protective layer 004 and the second protective layer 003 are light-transmitting layers with a harderness higher than that of the waveguide layer 002 , and are used to protect the waveguide layer 002 from collision.

[0053] In the present application, the first protective layer 004 and the second protective layer 003 are provided to protect the waveguide layer 002 from external impact and wear, while also ensuring the transparency and durability of the overall structure.

[0054] As a feasible embodiment, the first protective layer 004 is located above the waveguide layer 002, and plays a direct protective role, and the second protective layer 003 is located below the waveguide layer 002, and also plays a protective role, and also helps to fix the position of the waveguide layer 002. For example, the first protective layer 004 and the second protective layer 003 should be selected to have sufficient hardness to prevent scratches and damages in daily use, while maintaining good light transmission performance.

[0055] For example, the image source assembly 001 can be disposed at the lower portion of the windshield 006 .

[0056] For example, Figure 2 As shown, the image source component 001 and the driving position 005 are located on the same side of the windshield 006. When the image source component 001 generates a projection beam of a picture to be displayed, the projection beam propagates in the order of the image source component 001, the first reflection texture 0021, the inside of the waveguide layer 002, the second reflection texture 0022, and the driving position 005.

[0057] For example, Figure 3 As shown, the image source component 001 and the driving position 005 are located on different sides of the windshield 006. When the image source component 001 generates a projection beam of a picture to be displayed, the projection beam propagates in the order of the image source component 001, the first reflection texture 0021, the inside of the waveguide layer 002, the second reflection texture 0022, and the driving position 005.

[0058] In the present application, the image source assembly 001 can be installed at the lower part of the windshield 006. This layout is conducive to utilizing the space inside the vehicle while reducing obstruction to the driver's field of vision.

[0059] For example, the image source component 001 can be disposed on the side of the wind shield 006. The following takes the image source component 001 disposed on the right side of the wind shield 006 as an example and explains it in conjunction with the drawings.

[0060] For example, Figure 4 As shown, the image source component 001 and the driving position 005 are located on the same side of the windshield 006. When the image source component 001 generates a projection beam of a picture to be displayed, the projection beam propagates in the order of the image source component 001, the first reflection texture 0021, the inside of the waveguide layer 002, the second reflection texture 0022, and the driving position 005.

[0061] For example, Figure 5 As shown, the image source component 001 and the driving position 005 are located on different sides of the windshield 006. When the image source component 001 generates a projection beam of a picture to be displayed, the projection beam propagates in the order of the image source component 001, the first reflection texture 0021, the inside of the waveguide layer 002, the second reflection texture 0022, and the driving position 005.

[0062] In the present application, in addition to installing the image source assembly 001 at the bottom of the windshield 006, another option is to install the image source assembly 001 on one side of the windshield 006, which can further optimize the use of the space inside the vehicle and may simplify the mechanical design of the device.

[0063] In the present application, if the image source component 001 and the driving position 005 are located on the same side of the windshield 006, it is necessary to ensure that the light is correctly transmitted to the driver's front line of sight through a specific angle and reflection mechanism. If the image source component 001 and the driver are located on different sides of the windshield 006, the light needs to undergo more reflections to reach the driver's line of sight, which may require a more complex optical design to achieve. Therefore, the image source component 001 and the driving position 005 are located on the same side of the windshield 006, which is regarded as a preferred setting mode of the present application.

[0064] In this application, the following requirements are imposed on the various components of the vehicle-mounted head-up display device. The waveguide layer 002 can be made of high-quality transparent materials to ensure good optical performance. The first reflection texture 0021 adopts a precise microstructure design to ensure that the light beam accurately enters the waveguide layer 002 for full reflection propagation. The second reflection texture 0022 also adopts a precise microstructure to ensure that the light beam is emitted at a suitable angle to the driver's line of sight. The protective layer needs to have a material with sufficient hardness and light transmittance to protect the waveguide layer 002 from damage and ensure that the display effect is not affected. The image source component 001 needs to have high resolution, fast response capability, and the ability to adapt to different lighting conditions.

[0065] The vehicle-mounted head-up display device of the present application realizes clear and stable image display through the unique waveguide layer 002 design and reflective texture. At the same time, by setting the image source component 001 at different positions of the windshield 006, it can be flexibly adjusted according to the specific needs and internal layout of the vehicle. In addition, the addition of the first protective layer 004 and the second protective layer 003 improves the overall durability and safety of the equipment, making the vehicle-mounted head-up display device more suitable for use in complex and changeable vehicle environments. While realizing the head-up display based on the vehicle-mounted windshield 006, the head-up display device has a smaller size and no ghosting compared to the existing reflector structure, which reduces the equipment cost and deployment cost of the vehicle-mounted head-up display device.

[0066] The present application also provides a vehicle based on the above-mentioned embodiments, which is used to load the vehicle-mounted head-up display device of any of the above-mentioned embodiments, including a windshield and an image source assembly, the windshield including a waveguide layer, and the waveguide layer is provided with a first reflective texture and a second reflective texture.

[0067] The present application also provides a method embodiment that is consistent with the above embodiment, which is used to control the vehicle of the above embodiment to perform display control on a vehicle-mounted head-up display device loaded on the vehicle.

[0068] The embodiment provided in this application is an embodiment of a vehicle control method.

[0069] Combine the following Figure 6 The embodiments of the present application are described in detail.

[0070] Figure 6 A flow chart of a vehicle control method of the present application is shown as follows: Figure 6 As shown, the process includes the following steps S601 and S602.

[0071] In step S601, in response to the vehicle being triggered to display an image based on the vehicle-mounted head-up display device, the image source component is controlled to generate a projection light beam of the image to be displayed.

[0072] In step S602, the image source component is controlled to project the projection light beam onto the first reflection texture, so that the projection light beam is incident on the waveguide layer based on the first reflection texture, and is totally reflected and propagated in the waveguide layer, so that the projection light beam that is totally reflected and propagated in the waveguide layer is emitted from the second reflection texture to the driving seat.

[0073] Through the vehicle control method provided by the present application, the display control of the vehicle head-up display device described in any of the above embodiments can be realized, which can quickly respond to the driver's needs, display necessary information in a timely manner, and improve driving safety. On this basis, the present application can display different information according to different driving conditions, such as navigation instructions, speed, warning information, etc., while reducing the driver's operation steps, and only a simple trigger action is needed to start the display function.

[0074] In addition, the present application can perform stable display. Even if the vehicle is traveling on a bumpy road, the displayed image will not be greatly affected because the propagation path of the light beam in the waveguide layer is fixed, thus ensuring the continuity of the information.

[0075] The present application adopts efficient optical transmission and utilizes the principle of total reflection to reduce the loss of light beams during transmission, thereby ensuring the brightness and clarity of the display. Through the internal reflection of the waveguide layer, the entire system can be made very compact, saving space inside the vehicle. Compared with the traditional vehicle-mounted head-up display device that uses a reflector for head-up display, the vehicle-mounted head-up display device of the present application can have a smaller size and does not have the problem of ghosting, and the hardware requirements and the cost of eliminating ghosting can be reduced.

[0076] Figure 7 A flow chart of another vehicle control method of the present application is shown. Figure 7 As shown, the process includes the following steps S701 and S702.

[0077] In step S701, in response to the vehicle being triggered to display an image based on the vehicle-mounted head-up display device, the image source component is controlled to generate a projection light beam of the image to be displayed.

[0078] In step S702, the image source component is controlled to project the projection light beam onto the first reflection texture, so that the projection light beam is incident on the waveguide layer based on the first reflection texture, and is totally reflected and propagated in the waveguide layer, so that the projection light beam that is totally reflected and propagated in the waveguide layer is emitted from the second reflection texture to the driving seat.

[0079] In step S703, in response to the vehicle being triggered to adjust the display orientation of the image display, the image source component is controlled to adjust the exit point of the projection light beam.

[0080] The method provided in the present application adjusts the incident angle by controlling the image source component to adjust the exit point of the projection light beam. When the projection light beam is incident along the first reflection texture and then exits along the second reflection texture, the final display orientation will also change accordingly, thereby achieving the effect of adjusting the display orientation.

[0081] This application allows drivers to adjust the display orientation according to their line of sight height and position preferences, which can adapt to drivers of different heights and sitting postures, ensuring that all users can clearly see the display information. At the same time, it can ensure that the display information is always in the best viewing position to avoid safety hazards caused by line of sight deviation.

[0082] The vehicle control method provided by the present application significantly improves the response speed, information transmission efficiency and personalized adaptability of the vehicle head-up display system through intelligent image source component control and efficient optical transmission mechanism. This method not only improves the driver's experience, but also enhances driving safety, especially in complex driving environments, and can better assist the driver in making correct decisions.

[0083] In practical applications, the method provided by the present application can be widely applied to various types of vehicles, from passenger cars to commercial vehicles and even special vehicles, all of which can benefit from it. In addition, with the development of autonomous driving technology, this head-up display system can further integrate the functions of advanced driver assistance systems (ADAS) to provide strong support for future intelligent transportation systems.

[0084] The present application also provides an apparatus embodiment that is consistent with the above embodiment, which is used to implement the method steps of the above embodiment. The explanation based on the same name meaning is the same as the above embodiment, and has the same technical effect as the above embodiment, which will not be repeated here.

[0085] like Figure 8 As shown, the present application provides a vehicle control device 800, including a monitoring unit 801 and a control unit 802

[0086] The monitoring unit 801 is used to monitor the control triggered by the vehicle.

[0087] The control unit 802 controls the image source component to generate a projection beam of the image to be displayed in response to the vehicle being triggered to display an image based on the vehicle head-up display device. And controls the image source component to project the projection beam to the first reflection texture, so that the projection beam is incident on the waveguide layer based on the first reflection texture, and is fully reflected and propagated in the waveguide layer. The projection beam fully reflected and propagated in the waveguide layer is emitted from the second reflection texture to the driving position.
