Specifically, the display light is emitted by the optical machine of the HUD display device, and is projected on the windshield through the corresponding optical lens to produce a corresponding virtual image, which forms an enhanced display effect with the real world outside the windshield. However, the interface configuration in the projection area of ​​the HUD display device is pre-designed, and the size and position of each display element are relatively fixed.

[0054] According to the above description, the optional implementation mode supports the user to set the display elements in the preview interface equivalently, so as to make up for the fact that the projected virtual image cannot be directly adjusted by the input method of dragging.

[0078] The present application will be described in detail below in conjunction with the accompanying drawings, but the content of the description is merely some examples recorded in the present application and does not limit the present application. Changes in structure, method, function, etc. made by ordinary technicians in this field based on these examples are included in the protection scope of the present application.

[0079] It should be noted that the same reference numerals or marks may be used in different examples, but these do not represent an absolute connection in structure or function. In addition, the "first", "second", etc. mentioned in each example are only for the convenience of description, and do not represent an absolute distinction in structure or function, nor can they be understood as indicating or implying the relative importance or the number of corresponding objects. Unless otherwise specified, the "at least one" that may be involved in the description refers to one or more, and "more than one" refers to two or more.

[0080] In addition, when expressing a feature, the character " / " can indicate that there is an or relationship between the front and back associated objects. For example, head-up display / head-up display can be expressed as head-up display or head-up display. When expressing an operation, the character " / " can indicate that there is a division relationship between the front and back associated objects. For example, the magnification M=L / P can be expressed as L (virtual image size) divided by P (image source size). Moreover, the "and / or" in different examples is only to describe the association relationship between the front and back associated objects. This association relationship can include three situations. For example, a concave mirror and / or a convex mirror can be expressed as the existence of a concave mirror alone, the existence of a convex mirror alone, and the existence of both a concave mirror and a convex mirror.

[0081] HUD projection display mainly uses the optical reflection principle to reflect the imaging light to be displayed through a transparent surface into the viewer's eyes. The human eye can see the virtual image information in the opposite direction of the light. Correspondingly, the transparent surface can be the windshield of the vehicle, and the windshield can be used as a display screen to display the navigation instructions of the vehicle, the vehicle's driving speed, etc. Figure 1As shown, the HUD display device may include at least an optical machine 1, a first reflector 2, a second reflector 3, etc., wherein the optical machine 1 includes a backlight source and an image source (not shown), the backlight source is used to provide illumination light and adjust the brightness of the illumination light according to control, for example, the backlight source may be an LED (Light Emitting Diode), a laser, etc. Under the illumination light provided by the backlight source, the image source adjusts the corresponding display content according to control and projects the display light from the surface of the image source, for example, the image source may be an LCD (Liquid Crystal Display), a DMD (Digital Micromirror Devices), a MEMS (Micro-Electro-Mechanical System) micromirror, a LCOS (Liquid Crystal on Silicon), etc. The first reflector 2 and the second reflector 3 can project the display light projected by the optical machine 1 onto the windshield 4, so as to customize the optical path in a smaller space and meet different projection display requirements. The first reflector 2 and the second reflector 3 can be set as a concave mirror, a convex mirror, a concave lens, a convex lens, etc. according to the requirements of optical planning, and the surface shape of the lens can adopt a free-form surface. Optionally, at least one of the first reflector 2 and the second reflector 3 can also be adjusted to a certain degree of angle, so as to change the projection position of the display light on the windshield 4 to meet the needs of viewers of different heights. The display light of the optical machine 1 is finally reflected on the windshield 4 of the vehicle to form a virtual image 5. When the human eye 6 observes the virtual image 5 facing the windshield 4, it can feel a certain sense of depth, just like watching a real object at a specific distance outside the windshield. The virtual image 5 can be the navigation instruction content, vehicle speed, etc. as described above. It should be added that, according to the characteristics of different optical machines, the HUD display device can also be provided with a diffuser. In some examples, the HUD display device can also include Fresnel lenses, waveguide optical devices, diffractive optical devices, holographic optical devices, tapered optical fibers, etc.

[0082] As mentioned above, the virtual image formed by the HUD display device projecting on a transparent surface such as a vehicle windshield is generally viewed from the outside of the vehicle windshield. Figure 2As shown, the specific form of expression is a projection area 50 that can carry various display elements. The projection area 50 is facing the road ahead and can also form a fitting relationship with the road to display corresponding enhanced display elements. The content in the projection area 50 can be determined by the display light projected by the optical machine, and can be specifically realized by configuring the image source display content in the optical machine. Accordingly, the range of the projection area 50 is related to the display surface range of the image source. It should be noted that the display light emitted from the image source display surface will produce certain distortion after being transmitted by the optical system, that is, the display shape in the projection area will have a certain change from the display shape on the image source display surface. In order to ensure that the content viewed by the human eye in the projection area is in a normal state, it is necessary to pre-correct the corresponding content on the image source display surface to offset the distortion in optical transmission. In this example, the projection area 50 is configured with display elements 51, 52, and 53. Display element 51 may be the speed limit information of the current road, display element 52 may be the speed information of the current vehicle, and display element 53 may be the gear information of the current vehicle. Such information may be used as auxiliary information for the driver to drive the vehicle, thereby reducing the frequency of the driver lowering his head to check the instrument panel or the central control screen, mobile phone, etc. However, display elements 51, 52, and 53 are subject to the limitation that the HUD display device can only project and display. The position and size of each display element in the projection area 50 are designed in advance and are fixed once they leave the factory. This results in that the specific information arrangement cannot meet the aesthetic needs of each user. For example, some users think that display element 51 is too large, and some users think that the gear information corresponding to display element 53 is not needed, and the flexibility is poor.

[0083] In some examples, in order to increase the flexibility of display element configuration, such as Figure 3 As shown, the projection area 50 is divided finely, that is, the projection area is divided into a number of small units by a plurality of standard grids 501 arranged in a horizontal and vertical array. Each small unit can be a square, which not only determines the size of the small unit, but also determines its position in the projection area 50 by the horizontal and vertical sequence. Figure 4 As shown, the side length of a single standard grid 501 is determined according to the minimum resolution unit of the human eye 6, that is, the minimum horizontal distance and vertical distance that the human eye 6 can distinguish are used as the side length of the standard grid 501, so as to avoid the side length of the standard grid 501 being too small and unable to be distinguished by the human eye, and too large resulting in insufficient adjustment precision, thus compressing the adjustment space. Figure 5As shown, the arrangement of display elements in the projection area 50 depends on the arrangement of the standard grids 501, so that display elements of different shapes and sizes can be formed by combining any number of adjacent standard grids 501. Taking display element 52 as an example, display element 52 occupies 21 (3*7) standard grids 501, which is an integer multiple of the standard grid 501, and is displayed from bottom to top against the bottom surface, and from left to right starting from the 13th standard grid 501 in the horizontal direction. This method is first easier to locate, and can also be fine-tuned in the horizontal and vertical directions according to the step size of the smallest standard grid 501. More importantly, the size of all display elements is limited by the number of standard grids 501, which is more standardized and easier to plan multiple display elements in a unified manner. At the same time, the standard grid 501 is the smallest unit that can be distinguished by the human eye, so it is possible to accurately determine the position where the human eye's line of sight stays, and count the length of time the human eye watches a specific display element, serving the analysis and prediction of user usage habits and other aspects. Accordingly, in order to adjust the size of the display element 52, the control can be achieved through the buttons connected to the HUD display device, such as the increase button, the decrease button, the left button, the right button, the up button and the down button set on the steering wheel, etc., optionally, these buttons can also be virtual buttons on the vehicle-mounted central control screen. In some examples, in response to the user pressing the increase button or the decrease button, the number of standard grids 501 occupied by the display element can be changed, thereby changing the size of the display element, such as the increase button corresponding to the triggering display element to reduce the occupation of a standard grid 501 in the horizontal and vertical directions. In response to the user pressing the left button or the right button, the position of the display element can be adjusted in the horizontal direction, such as moving a column of standard grids 501 to the left or right in the projection area 50, respectively. In response to the user pressing the up button or the down button, the position of the display element can be adjusted in the vertical direction, such as moving a row of standard grids 501 up or down in the projection area 50, respectively. Optionally, the above-mentioned multiple buttons can also reuse a single button, and use the different trigger actions of the button to bind its adjustment function, thereby reducing the number of buttons set.

[0084] The HUD display device can also support adding element buttons and deleting element buttons, such as Figure 6As shown, in response to the user pressing the add element button, a display element 51 can be added to the projection area 50 on the basis of the display element 52, so as to meet the diverse needs of the user. The added display element 51 occupies 9 standard grids 501, which is also an integer multiple of the standard grid 501, and is displayed from bottom to top against the bottom surface, and starts to be displayed from the 9th standard grid 501 horizontally from left to right. It can also be adjusted in response to the user pressing the increase button, the reduction button, the left move button, the right move button, the up move button and the down move button. Accordingly, in order to support the adjustment of different display elements, the adjustment of different display elements can also be supported by switching the objects of adjustment. At the same time, if any display element is the current adjustment object, in response to the user pressing the delete element button, the corresponding display element will also be deleted from the projection area 50. In some examples, the display element 51 and the display element 52 are positioned by the standard grid 501, and each of them occupies an integer multiple of the standard grid 501 according to the size of the design. Furthermore, there will be no overlap between display element 51 and display element 52, that is, display element 51 and display element 52 will not occupy the same standard grid 501. Optionally, when the user triggers the addition of a display element and there is another display element at the default position or adjusts the position of a display element to be closer to another display element, the display element will be adaptively adjusted according to the occupancy of the corresponding standard grid 501, for example Figure 6 When a column of standard grids 501 occupied by the right side of the display element 51 overlaps with a column of standard grids 501 occupied by the left side of the display element 52, the display element 51 will automatically move one column of standard grids 501 to the left in the horizontal direction or the display element 52 will automatically move one column of standard grids 501 to the right in the horizontal direction. Optionally, the process of adaptive adjustment can also be presented in the form of animation, for example, the movement between the display element 51 and the display element 52 can simulate the change in movement speed under the repulsive force between the two. It should be noted that in the normal projection process in the projection area 50, that is, during the driving process of the vehicle, the lines constituting the standard grid 501 will not be directly displayed in the projection area to avoid interfering with the driver's line of sight. Optionally, the standard grid 501 in the projection area 50 can be automatically displayed when the user manipulates the above-mentioned buttons to configure the display elements, and after the configuration is completed, it can support automatic hiding.

[0085] In some examples, the HUD display device may receive the user's configuration of the display elements by means of other input devices in the vehicle, such as Figure 7As shown, you can use the vehicle-mounted central control screen. The vehicle-mounted central control screen has a touch screen. The advantage of the touch screen is that the area for input operations is the same as the area for information display, so the corresponding drag operation can be implemented. In this example, the vehicle-mounted central control screen 10 and the HUD display device, as important display components in the cockpit domain, can communicate with each other. The touch screen display of the vehicle-mounted central control screen 10 is divided into two parts, namely the preview interface 11 and the operation interface 12. The user can directly drag the display elements on the preview interface 11 to realize the configuration of the display elements in the projection area. The corresponding standard grid 101 will be displayed in the preview interface 11 as a reference for the positioning of the display elements, and the operation interface 12 may include several display elements to be configured (not shown in the figure). The configuration linkage between the vehicle-mounted central control screen 10 and the HUD display device will be described in detail below. As shown Figure 8 As shown, the HUD display device can also receive the user's configuration of the display elements with the help of a mobile terminal 20 such as a mobile phone. In this example, the mobile terminal 20 can be paired with the HUD display device or the cockpit domain through a wireless method such as Bluetooth or WiFi. For example, when a user carrying a mobile terminal 20 enters a vehicle, the vehicle will automatically connect to a nearby mobile terminal 20 after it is started. In this way, the mobile terminal 20 can interact with the HUD display device and obtain the configuration instructions entered by the user from the mobile terminal. In this example, when the user opens the HUD display device app or the vehicle app in the mobile terminal 20 to enter the projection setting interface, it will automatically connect to the HUD display device and be in configuration mode. The interface of the mobile terminal 20 can display two parts on the left and right. One part is a preview interface 21. The user can directly drag the display elements on the preview interface 21 to configure the display elements in the projection area. The corresponding standard grid 201 will be displayed in the preview interface 21 as a reference for the positioning of the display elements. The other part is an operation interface 22, which can be used to carry a number of display elements to be configured (not shown in the figure). Figure 7 The examples are similar.

[0086] Accordingly, for the touch screen including the preview interface and the operation interface, the information distribution in the projection area corresponding to the HUD display device can proportionally replicate the information distribution in the preview interface under the premise of connection, and the information distribution in the preview interface comes from the user's configuration input. Fig. 9As shown, taking the display elements in the projection area 50 configured on the vehicle-mounted central control screen 10 as an example, the display elements in the preview interface 11 will be correspondingly presented in the projection area 50. For example, the middle bottom of the preview interface 11 is configured with a display element 52, and the display element 52 will also be projected in the middle bottom of the projection area 50. Among them, the size and position of the display elements in the projection area 50 are proportional to the corresponding display elements configured in the preview interface 11, which can provide users with a very smooth setting experience. Users can directly adjust and judge the beauty of their distribution in the preview interface 11. After the setting is completed, they can also watch the actual effect in the projection area 50, so as to determine the corresponding optimization strategy and implement fine-tuning in the corresponding direction in the preview interface 11. Optionally, the user's adjustment on the preview interface 11 will be synchronized in real time in the projection area 50, and the user can immediately view the presentation effect of each step of the adjustment in the projection area 50 during the adjustment process. It can also be that the final adjustment result of the user on the preview interface 11 is triggered to take effect in the projection area 50 by submission, reducing the pressure of frequent rendering of the HUD display device. Several second standard grids 101 are displayed in the preview interface 11. The second standard grids 101 constitute the entire range of the preview interface 11 corresponding to the projection area 50. Correspondingly, the projection area 50 is divided into several minimum units by the first standard grid. In this example, the first standard grid is not directly displayed in the projection area 50. Specifically, the first standard grid in the projection area 50 corresponds to the second standard grid 101 in the preview interface 11 one by one, and the number and position sequence are consistent, so that each position in the projection area 50 corresponds to each position in the preview interface 11 one by one. The ratio between the first standard grid and the second standard grid 101 is determined according to the limiting relationship between the projection area 50 and the preview interface 11. This is because the range size of the preview interface 11 is related to the display space of the touch screen, and is not necessarily the same as the projection range of the projection area 50. The first standard grid can use the minimum resolution unit under the visual limit of the human eye, and the size of the second standard grid 101 is determined according to the first standard grid. Accordingly, if the range of the preview interface 11 is larger than the projection area 50, the single second standard grid 101 will be larger than the single first standard grid; if the range of the preview interface 11 is smaller than the projection area 50, the single second standard grid 101 will be smaller than the single first standard grid; if the range of the preview interface 11 is the same as the projection area 50, the single second standard grid 101 will be the same size as the single first standard grid, so that the content configured in the preview interface 11 and the content displayed in the projection area 50 can be synchronized.When a specific display element occupies a specific multiple of the second standard grid 101 in the preview interface 11, it will correspondingly occupy the same multiple of the first standard grid in the projection area 50. When counting the time the user views the specific display element, it is only necessary to directly add up the time the user's gaze stays on the corresponding first standard grid of the specific multiple.

[0087] exist Fig. 9 In the example, the operation interface 12 includes several display elements to be configured, such as display element 51, display element 53 and display element 54. Each display element realizes different functional displays. These display elements can be added to the preview interface 11, and in order to adapt to the second standard grid 101 in the preview interface 11, all display elements adopt a square design. Optionally, the corners of the square design can be rounded to improve the aesthetics. Optionally, different display elements can have a default size in the operation interface 12. The default size can be the recommended size for the display element to be configured in the preview interface 11, so different display elements are presented in different sizes in the operation interface 12. Fig.10As shown, when it is necessary to add the display element 51 to the preview interface 11, so as to achieve the effect of projecting the display element 51 in the projection area 50, the finger can be directly used to drag it. Specifically, when the user presses and holds the display element 51 in the operation interface 12, the display element 51 enters a draggable state. As the finger is dragged, the display element 51 will also move along with the position where the finger and the touch screen are in contact with each other, so that the display element 51 can be dragged from the operation interface 12 to the preview interface 11. When the display element 51 is completely in the preview interface 11, the finger leaving the touch screen will trigger the display element 51 to be fixed near the finger release position, and it is based on the second standard grid 101 around the release position, and it occupies a corresponding integer multiple of the second standard grid 101, and the specific multiple is determined by the configured display element size. Accordingly, when the released display element 51 is not aligned with any second standard grid 101 in the preview interface 11, fine adjustment will be performed to align the square edge of the display element 51 with the line of the corresponding second standard grid 101, preferably aligned with the closest grid line, to ensure that it is positioned exactly on the second standard grid 101 arranged in integers, and the entire automatic fine adjustment process is subject to the positioning constraint of the second standard grid 101. Further, when the released display element 51 conflicts with the display element 52 on the right, that is, the display element 51 and the display element 52 occupy at least one same second standard grid 101 in the preview interface 11, the position of the display element 51 or the display element 52 will be automatically fine-tuned to stagger the two. For example, the rightmost column of the second standard grid 101 occupied by the display element 51 overlaps with the leftmost column of the second standard grid 101 occupied by the display element 52, which will inevitably affect the viewing effect. The display element 51 will automatically shift two columns of the second standard grid 101 to the left to an adjacent position, so that there is a certain gap between the two. Optionally, the fine-tuned positioning is automatically adjusted according to the predefined number of occupied grids.

[0088] In some examples, when the display element 51 is relatively fixed in the preview interface 11, for example, it is not the final position, but the fifth position where it stays in the middle, the trend of further manual adjustment of the display element 51 can be observed according to the effect after fixation. Correspondingly, the user can also press the display element 51 with a finger, that is, activate the draggable state of the display element 51 in the fifth position. As the finger moves in the preview interface 11, the display element 51 will still move with it. The user can move it to the first position on the left side of the display element 52 by observation. When the finger is released again, the display element 51 will adaptively occupy the second standard grid 101 corresponding to the integer multiple of the first position around. As described above, the display element not only supports the position configuration in the preview interface 11, but also supports the configuration of the size of the display element itself. In some examples, the size setting of the display element can be adjusted before dragging the display element, that is, it can be adjusted in the operation interface 12, or it can be adjusted in the preview interface 11 after dragging the display element. Adjusting the size of the display element can be performed by selecting a specific display element operation, and it is realized by sliding or clicking a specific size adjustment button or slider on the touch screen. In more examples, for display elements on the preview interface 11 or the operation interface 12, you can also click on the location of the display element to trigger the display element to switch between optional sizes, and switch the size once each click until it switches to the size required by the user. After switching the size in the preview interface 11, if there is a conflict with other surrounding display elements, the position will be automatically adjusted to avoid adjacent display elements. If the distribution of the display elements in the original position after the size adjustment is not coordinated and affects the appearance, the user can further use the dragging method in the above example to re-move the position.

[0089] In some examples, such as Fig.11As shown, for the previously configured display elements that do not need to be projected in the projection area 50, specific display elements can also be operated directly in the preview interface 11. Taking the display element 52 as an example, the user does not want to see the vehicle speed information in the projection area 50, and wants to make room for displaying other required information. Accordingly, the user can press and hold the display element 52 with a finger in the preview interface 11. As mentioned above, the display element 52 enters the draggable state again. At this time, the display element 52 can be dragged to the operation interface 12 with a finger until it is completely dragged onto the operation interface 12. At this time, release the finger, and the display element 52 will move from the preview interface 11 to the operation interface 12. The display element 52 can be placed at the position where the finger is released, or the display element 52 is at the default position in the operation interface 12. Based on the corresponding synchronization relationship, since the display element 52 in the preview interface 11 is removed, the display element 52 in the projection area 50 will also be deleted synchronously. Optionally, the display element 52 dragged to the operation interface 12 will also automatically restore to the default size for listing. Furthermore, other display elements may be added to the original position of the display element 52 in the preview interface 11 , and specifically, the required display elements may be dragged from the operation interface 12 .

[0090] In some examples, such as Fig.12 As shown, the first block 510 and the second block 530 can also be simultaneously delineated in the projection area 50 and the preview interface 11. Fig.12The dividing line between the first block and the second block in the preview interface 11 is not shown in the figure. The positions of the first block and the second block between the projection area 50 and the preview interface 11 correspond to each other one by one. The difference in the block range between the two can refer to the above example and is also determined according to the contraction relationship between the projection area 50 and the preview interface 11. In this example, the display element to be configured can also be dragged to the corresponding position of the preview interface 11 in response to the user's drag operation, but when the display element is dragged to the corresponding position of the preview interface 11 and is in the first block or the second block, the size and / or position of the display element will be automatically configured, and the automatically configured display element will also be reflected in the first block 510 or the second block 530 corresponding to the projection area 50. Specifically, the display element in the first block will be automatically configured to the first size, for example, the display element 51 will be automatically adjusted to the first size after being dragged to the first block of the preview interface 11, and the display element in the second block will be automatically configured to the second size, for example, the display element 53 will be automatically adjusted to the second size after being dragged to the second block of the preview interface 11. At the same time, the display elements in the first block can also be arranged according to the first preset rule according to the number of display elements in the block, for example, in the first block, the display elements 51 are arranged from right to left in a right-aligned manner, and the display elements in the second block can also be arranged according to the second preset rule according to the number of display elements in the block, for example, in the second block, the display elements 53 are arranged from left to right and from top to bottom in a left-aligned manner, and the arrangement in the projection area 50 will also synchronize with the arrangement in the preview interface 11, reducing the user's fine-tuning intervention, making the configuration faster and more convenient, and the arrangement rules are more unified, which can reduce space waste. In some examples, when the display elements are dragged to the first area or the second block of the preview interface 11, they will be set to the same size, but the arrangement rules of the display elements in different blocks are different, for example, in the first block, the display elements are arranged from right to left, and in the second block, the display elements are arranged from left to right. In some examples, in addition to the display elements configured in different blocks being arranged according to the preset rules corresponding to the different blocks, the sizes of the display elements are not strongly associated with the different blocks. Instead, referring to the above examples, they can be configured according to the default size of the original display elements in the operation interface 12, or they can be configured according to the size after the user sets the size, that is, the first position of the first display element after being dragged is in the first block, and the first display element is arranged in the first block according to the size of the display element and the first preset rule; the first position of the first display element after being dragged is in the second block, and the first display element is arranged in the second block according to the size of the display element and the second preset rule.

[0091] It should be noted that the configuration of all display elements in the preview interface 11 can be reflected in the projection area 50 in real time. For example, each completed operation will trigger synchronization to the projection area 50, so that the user can gradually view the final configuration effect in the projection area 50 and make corresponding adjustments at any time. Figure 9-12 , the operation performed by the user on the touch screen, such as dragging the display element in the operation interface to the preview interface, does not immediately take effect in the projection area in response to each step of the operation, that is, the projection area will not immediately display the display element dragged to the preview interface. Instead, after the user completes the configuration of all display elements in the preview interface, it is triggered by certain effective conditions, such as pressing the submit button on the touch screen, or the user does not operate for more than a specific time range, and then the configuration results in the preview interface will be uniformly synchronized to the projection area, and the information distribution in the projection area is consistent with the configuration distribution in the preview interface. In a specific example, for the synchronization of the configuration results in the preview interface to the projection area, it is the touch screen and the HUD display device that communicate and interact, and display them synchronously on the image source display surface in proportion according to the size relationship between the image source display surface and the projection area and the preview interface, respectively. The display light emitted by the image source display surface is finally reflected by the windshield to form a virtual image that can be viewed by the human eye in the projection area. Furthermore, the display screen on the image source display surface will also be pre-corrected based on the configuration results of the preview interface. The pre-correction can ensure that the display elements projected in the projection area are in a normal shape and are not affected by the distortion of optical transmission.

[0092] When the HUD display device implementing the display configuration method in the above example is applied to a vehicle, the information distribution efficiency in the projection area can be optimized, and information can be displayed on demand, thereby improving the human-computer interaction experience. Fig.13 As shown, the HUD display device integrated in the vehicle can be powered and data by the vehicle computer 92, or the HUD display device itself can provide power and generate data. The HUD display device can specifically include a processor 91, an Ethernet interface 901, a CAN (Controller Area Network) interface 902, a power management module 903, a running memory 904, a storage memory 905, a temperature detection 906, a motor 907, a backlight source 908, an image source 909, a positioning module 910, a radar 911, a camera 912, etc. It should be noted that Fig.13 The modules listed in the description are merely exemplary and do not constitute any limitation. In some examples, the HUD display device may further include other modules. In addition, the above modules may be implemented in one or more hardware in different examples, or a single module may be implemented by a combination of multiple hardware.

[0093] The processor 91 serves as the control center of the HUD display device, and includes one or more processing units of any type, including but not limited to a microcontroller, a microcontroller, a DSP (Digital Signal Processor) or any combination thereof. The processor 91 is used to generate operation control signals according to a computer program, realize the control of other modules, and cooperate with corresponding modules to process the acquired or inherent data, instructions, etc.

[0094] The Ethernet interface 901 is a network data connection port for local area network communication, which defines a series of software and hardware standards. Multiple electronic devices can be connected together through the Ethernet interface 901. In this example, the processor 91 can exchange information with the vehicle computer 92 through the Ethernet interface 901, such as sending data to the vehicle computer 92 or receiving data sent by the vehicle computer 92.

[0095] The CAN interface 902 is a network data connection port of the controller area network, which provides a standard bus for the control system and embedded industrial control inside the car, and realizes the communication interaction between the control nodes. In this example, the processor 91 can also exchange information with the vehicle computer 92 through the CAN interface 902. Optionally, the processor 91 can also connect to other external devices through the CAN interface 902. In some examples, the processor 91 can also be provided with a GPIO (General-purpose input / output) interface to improve the compatibility of peripheral connections.

[0096] The power management module 903 is connected to the vehicle computer 92 and can receive the power provided by the vehicle computer 92 to provide a regulated power supply for each module of the HUD display device, thereby ensuring that the processor 91 and each module operate under normal voltage supply and avoid damage due to overvoltage.

[0097] The running memory 904 is used to store computer programs executed by the processor 91, temporarily stored calculation data, data exchanged with the storage memory, etc. The running memory 904 can be a memory such as SDRAM (Synchronous Dynamic Random-access Memory).

[0098] The storage memory 905 is used to store resources such as display content related to the HUD display device, and long-term storage of running programs and data, etc. The storage memory 905 can be a memory such as Flash (flash memory). In some examples, the processor 91 can also provide an interface to access an external memory.

[0099] Temperature detection 906 is used to detect the temperature inside the HUD display device, and may specifically include several temperature sensors. Since the resistance value of the temperature sensor changes with the change of temperature, the processor 91 can determine the resistance value of the temperature sensor at the corresponding temperature according to the voltage change between each temperature sensor and the voltage divider resistor under a fixed power supply voltage, thereby reversely deducing the temperature at the location of the temperature sensor. In some examples, the processor 91 can control several temperature sensors through the GPIO interface, and several temperature sensors can be set at different locations inside the HUD display device. The processor 91 can use time-sharing detection to obtain the temperature values ​​fed back by several temperature sensors respectively.

[0100] Motor 907 is used to drive the optical lens in the HUD display device to rotate under the control of processor 91, so as to achieve the change of the corresponding optical path. For example, when the backflow of sunlight causes the temperature rise on the surface of the image source, the motor can be used to drive the optical lens to prevent the external sunlight from reaching the surface of the image source. In some examples, the processor 91 can also drive the fan provided on the HUD display device through motor 907 to increase the speed of air exchange between the inside and outside of the HUD display device to achieve heat dissipation. Specifically, the motor 907 is connected to the processor 91 through a motor driver chip, and the motor driver chip provides high-performance power output for the motor 907, and can also communicate and control with the processor 91 through interfaces such as SPI (Serial Peripheral Interface).

[0101] The backlight source 908 is used to provide illumination light and adjust the brightness of the illumination light according to the control of the processor 91, so as to adjust the projection display brightness of the entire HUD display device. The backlight source 908 cooperates with the image source 909 to realize the main function of optical machine projection display. The backlight source 908 can be an LED (Light Emitting Diode), a laser, etc. Specifically, the backlight source 908 is connected to the processor 91 through a backlight driver chip, and the backlight driver chip provides a driving voltage for the backlight source 908 and controls the brightness of the backlight source 908 under the pulse width signal output by the processor 91.

[0102] The image source 909 is used to display an image of corresponding content and project the display light corresponding to the image according to the control of the processor 91. The image source 909 can be an LCD (Liquid Crystal Display), a DMD (Digital Micromirror Devices), a MEMS (Micro-Electro-Mechanical System) micromirror, a LCOS (Liquid Crystal on silicon), etc.

[0103] The positioning module 910 is used to monitor the position of the HUD display device and the corresponding vehicle. The positioning module 910 can be a global navigation satellite system such as GPS (Global Positioning System) and Beidou Satellite Navigation System. By measuring the distance between the satellite and the receiver on the positioning module 910 at different positions, the corresponding position and orientation data are determined. In some examples, the positioning module 910 may also include an inertial navigation system, which is based on Newton's laws of mechanics. By measuring the acceleration of the positioning module 910 in the inertial reference system, integrating it over time, and transforming it into the navigation coordinate system, the speed, yaw angle, and position data in the navigation coordinate system are obtained. Optionally, the inertial navigation system can assist the global navigation satellite system to achieve more accurate positioning and provide the processor 91 with corresponding position information.

[0104] The radar 911 is used to determine the position of a target object through electromagnetic waves, and can usually determine the distance of the target object from the vehicle where the radar 911 is located.

[0105] Camera 912 includes a vehicle body camera and an in-vehicle camera, wherein the vehicle body camera is used to determine the position of the target object through visual recognition, and the vehicle body camera can be a monocular camera or a binocular camera. The biggest difference between a monocular camera and a binocular camera is that a binocular camera can capture images from two different perspectives, thereby obtaining distance information in three-dimensional space. The in-vehicle camera is used to identify the behavior status of the driver and passengers in the vehicle, including fatigue detection, distraction detection, expression recognition, gesture recognition, sight tracking, etc. In this example, the in-vehicle camera can also implement eye tracking.

[0106] In some examples, the positioning module 910, radar 911 and camera 912 can also be directly connected to the vehicle computer 92, and are not directly connected to the processor 91 of the HUD display device. For example, the vehicle computer 92 itself is integrated with a positioning module for position tracking and a radar and camera for automatic driving. The HUD display device can obtain the collected data of the positioning module, radar and camera in real time through communication with the vehicle computer 92.

[0107] In some examples, such as Fig.14As shown, the HUD display device implementing the above display configuration method may specifically include a processor 931, a memory 932, an input device 933 and an output device 934, wherein the input device 933 may include an operation button integrated on the steering wheel, etc., and the display device may receive input control instructions and data through the input device 933. The output device 934 may include an image source integrated on the display device, etc., and the display device may output corresponding instructions or data to the output device 934. In addition, a communication device for information interaction with a vehicle-mounted central control screen or a mobile terminal may also be included, which is used to receive user input configuration results sent by an external device. Further, the memory 932 stores a computer program running on the processor 931, and the processor 931 implements the display configuration method of the above example when executing the computer program. In some examples, a computer-readable storage medium stores a computer program, and the computer program implements the display configuration method of the above example when executed by the processor.

[0108] like Fig.15 As shown, the vehicle can be provided with the above-mentioned HUD display device. Specifically, the HUD display device is integrated inside the center console 10, such as in front of the steering wheel. The corresponding display light is projected onto the opposite vehicle windshield 4 through the projection window 102 of the HUD display device. The effect of the viewer observing the windshield 4 from the cockpit is that the virtual image in the front projection area 50 can be directly seen. Specifically, it can be a display element reflecting various functions, and these display elements can be actively configured by the user. In some examples, the vehicle can also distribute the program for obtaining the display configuration method in the above example through the computer-readable storage medium of the above example, so that the vehicle-mounted HUD display device can be conveniently updated and upgraded. It should be noted that the above-mentioned vehicle is not limited to a car as a means of transportation, but can also include a bus, a truck, an excavator, a motorcycle, a train, a high-speed rail, a ship, a yacht, an airplane, a spacecraft, etc. The projected windshield is not limited to the front windshield of the car, but can also be a transparent surface at other positions.

For the convenience of description, the above description is divided into various modules and described separately according to their functions. Of course, when implementing the present application, the functions of each module can be implemented in the same or more software and / or hardware.

[0110] Through the description of the above examples, those skilled in the art can clearly understand that the present application can be implemented by means of software plus a necessary general hardware platform. Based on this understanding, the technical solution involved in the present application can be essentially or partly contributed to the prior art in the form of a software product.

The software is stored in a memory, such as a volatile memory (such as a random access memory, etc.), a non-volatile memory (such as a read-only memory, a flash memory, etc.) or any combination thereof.

[0111] In summary, this application supports flexible configuration of display elements in the projection area corresponding to the HUD display device. It receives the user's display element adjustment operation through the touch screen linked to the HUD display device and provides real-time feedback on the user's adjustment effect. The HUD display device maps the user-configured display elements to the corresponding position of the projection area according to the association between the preview interface in the touch screen and the projection area. This application supports flexible configuration of the information distribution of the projection area, and the display elements can be adjusted on demand according to the user's preferences, which greatly improves the user's viewing experience.
