Description

A floating display system control method, system, vehicle door and vehicle

[0001] The present application claims priority to Chinese application No. 2024108749267, filed on June 28, 2024, entitled "A floating display system control method, system, vehicle door and vehicle", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to, but is not limited to, the field of vehicle display, and particularly relates to a floating display system control method, system, vehicle door and vehicle. BACKGROUND

[0003] With the continuous development of display systems in vehicles, among them, the medium-free floating display technology is one of the development trends in the display field.

[0004] Currently, the medium-free floating display is prone to misoperation, which affects the user's experience. TECHNICAL SOLUTION

[0005] In a first aspect, the present application provides a floating display system control method, obtaining self-checking information; controlling the floating display system to project a floating image to a target area or issue a prompt information according to the self-checking information.

[0006] Implementing the above scheme, by judging the self-checking information of the floating display system, the possibility of misoperation of the floating display system is reduced, so as to ensure that the floating image presented by the floating display system is clear and complete, and the user has a good experience. For example, after the user turns on the floating display system, the user accidentally places other objects on the path through which the floating image projected by the floating display system passes. Through the above scheme, after determining that there is an obstruction on the path through which the floating image projected by the floating display system passes, a prompt signal is issued to the user, for example, by issuing a prompt sound, a prompt light, etc. The user can determine that there is an obstruction on the path according to the prompt signal, and the user can remove the obstruction to make the floating display system display a clear and complete floating image.

[0007] In a possible implementation manner of the first aspect, the method further comprises: in response to the self-checking information satisfying a target condition, controlling the floating display system to project a floating image to a target area.

[0008] In a possible implementation manner of the first aspect, the method further comprises: in response to the self-checking information not satisfying a target condition, issuing a prompt information, the prompt information being used to remind that the self-checking information does not satisfy the target condition.

[0009] In a possible implementation manner of the first aspect, the target condition comprises: there is no occlusion on a light transmission path, the light transmission path being a path of the floating display system projecting the floating image to the target area.

[0010] It can be understood that if there is an occlusion on the path through which the floating display system projects the floating image, the integrity and clarity of the floating image finally displayed by the floating display system will be affected, and therefore the condition that needs to be met by the self-checking information comprises that there is no occlusion on the path through which the floating display system projects the floating image.

[0011] Implementing the foregoing scheme can avoid the occlusion from causing the floating image to be incomplete and affecting the user experience.

[0012] In a possible implementation manner of the first aspect, the target condition further comprises: the height of the vehicle window glass being raised is greater than or equal to a preset height; and the floating display system is at least partially located on a side door of the vehicle.

[0013] Since when the floating display system needs to project the floating image to the target area through the side window glass of the vehicle, it is necessary to ensure that the side window glass of the vehicle meets certain height requirements, so as to facilitate complete reflection of light, therefore the condition that needs to be met by the self-checking information further comprises that the side window glass of the vehicle reaches the preset height.

[0014] In a possible implementation manner of the first aspect, before the self-checking information of the floating display system is acquired, the method further comprises: controlling a display device of the floating display system to be turned on.

[0015] Implementing the foregoing scheme can ensure the integrity and clarity of the floating image in the projection process of the floating display system, in the case that the floating display system is turned on and runs.

[0016] In a possible implementation manner of the first aspect, after the floating display system is controlled to project the floating image to the target area, the method further comprises: acquiring operation information of a user in the target area; and controlling the floating display system to display a floating image corresponding to the operation information according to the operation information.

[0017] In a possible implementation manner of the first aspect, the operation information comprises an operation position and an operation time, and before the floating image is controlled according to the operation information, the method further comprises: determining that the operation position is a valid position on the target area, and determining that the operation time is less than a preset time.

[0018] It can be understood that when the user operates the floating image of the floating display, the position of the operation can be a valid operation position (referring to a position that can actually trigger the content change of the floating image, such as the position of the application icon, the position of the on / off function option), or an invalid operation position (referring to a position that cannot trigger the content change of the floating image, such as the frame of the floating image, the blank area without application icons and function options, and the user's operation on the invalid operation position is usually a user's mistake), the duration of the operation can be a valid operation duration (such as 2 seconds), or an invalid operation duration (such as more than 2 seconds, more than 2 seconds is usually a user's mistake of directly touching the floating image without knowing), and the floating display system acquires the operation instruction of the user, judges whether the operation instruction is a valid operation instruction (referring to the operation instruction input by the user in the valid operation position and the valid operation duration), and only in the case that the operation instruction is a valid operation instruction, the picture is updated according to the operation instruction, so that the invalid operation instruction input by the user's mistake can be avoided to respond, and the user experience is optimized.

[0019] In a second aspect, the present application provides a floating display system, comprising: a display device configured to display view information; a reflection component configured to project the view information to a target area to form a floating image; and a self-checking device configured to detect whether the display device can project the view information to the target area to form the floating image through the reflection component.

[0020] In a possible implementation of the second aspect, the self-checking device is configured to control the display device to project the view information to the target area to form the floating image through the reflection component before acquiring the self-checking information of the floating display system.

[0021] In a possible implementation of the second aspect, the self-checking device is configured to control the display device to project the view information to the target area to form the floating image through the reflection component when the self-checking information meets a target condition.

[0022] In a possible implementation of the second aspect, the reflection component comprises a first reflection sub-component, a second reflection sub-component, and an optical element, and the first reflection sub-component, the optical element, and the second reflection sub-component are sequentially arranged in a path of the display device projecting the floating image to the target area.

[0023] In a possible implementation of the second aspect, the first reflection sub-component comprises a first mirror and a second mirror, the second reflection sub-component comprises a third mirror and a fourth mirror, and the first mirror, the second mirror, the optical element, the third mirror, and the fourth mirror are sequentially arranged in the path of the display device projecting the floating image to the target area.

[0024] In a possible implementation manner of the second aspect, the self-checking device is arranged between the third mirror and the fourth mirror, or arranged between the fourth mirror and the target area.

[0025] In a possible implementation manner of the second aspect, the fourth mirror is arranged on a side window of the vehicle.

[0026] In a possible implementation manner of the second aspect, the optical element is an equivalent negative refractive index slab lens.

[0027] In a possible implementation manner of the second aspect, the display device, the reflection assembly and the self-checking device are at least partially arranged inside a side door of the vehicle.

[0028] In a third aspect, the present application provides a vehicle door, wherein the vehicle door is configured with the floating display system in the second aspect and any possible implementation manner of the second aspect.

[0029] In a fourth aspect, the present application provides a vehicle, wherein the vehicle comprises the floating display system in the second aspect and any possible implementation manner of the second aspect, or the vehicle door in the third aspect. BRIEF DESCRIPTION OF DRAWINGS

[0039] Embodiments of the present application

[0040] The technical solutions related to the present application will be described clearly and completely in combination with the drawings. The embodiments described below are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0041] The terms "first", "second", and the like in the specification and claims of the present application and the above drawings are used to distinguish different objects, not to describe a specific order. In addition, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps is not limited to the listed steps, but can optionally include steps not listed, or can optionally include other steps inherent to the process, method, product or device.

[0042] It should be noted that the terms of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" in the present application are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0043] Floating display is a technology for generating images in the air based on the principle of light field reconstruction, which uses a flat lens to re-converge divergent light rays in the air to form an image, and the converged image does not need to be carried by a medium. At the same time, the floating display technology can also realize direct interaction between people and floating images by combining with interactive technology. Here, the floating image is the image of the floating display.

[0044] With the continuous development of intelligent cockpit systems in vehicles, the requirements of vehicle display technology are constantly updated. Among them, the floating display technology without medium is one of the development trends in the field of vehicle display.

[0045] Currently, the most commonly used floating display method without medium is to load a folding floating display system on the backrest of the front row seat of the vehicle. When displaying the floating image, this floating display system is prone to misoperation, for example, after the user opens and uses the floating display system, the user may place hands or other objects on the path through which the floating image projected by the floating display system will pass, resulting in incomplete or unclear floating images, thereby affecting the user's experience.

[0046] In view of the problems in the floating display method, the application provides a floating display system control method. The floating display system is located in a side door of a vehicle. The floating display system control method specifically comprises: obtaining self-checking information of the floating display system, and determining whether the self-checking information meets the condition for the floating display system to perform floating display; in the case where it is determined that the self-checking information does not meet the condition for the floating display system to perform floating display, sending prompt information to a user, the prompt information being used to remind the user that the self-checking information does not meet the condition for the floating display system to perform floating display. By determining whether the self-checking information of the floating display system meets the condition for the floating display system to perform floating display, the method can reduce the possibility of false operation of the floating display system, thereby ensuring the picture integrity and clarity of the floating image presented by the floating display system. The application provides a floating display system control method and system, a vehicle door and a vehicle. By determining whether the self-checking information of the floating display system meets the condition for the floating display system to perform floating display, the floating display system control method can reduce the possibility of false operation of the floating display system, thereby ensuring the picture integrity and clarity of the floating image presented by the floating display system.

[0047] The floating display system control method provided by the application will be described in detail below in combination with FIG. 1. Referring to FIG. 1, which is a flowchart of the floating display system control method provided by the application, as shown in FIG. 1, the floating display system control method comprises:

[0048] In S101, the computing device obtains self-checking information.

[0049] The self-checking information comprises:

[0050] whether there is an occlusion on the light transmission path and the height of the side window glass of the vehicle, wherein the light transmission path is the path of the floating display system for projecting a floating image to a target area, that is, the path through which the light emitted by the display device in the floating display system passes to finally form the floating image.

[0051] The process in which the computing device obtains the self-checking information can be performed before or after the floating display system displays the floating image. Here, the computing device obtains the self-checking information of the floating display system before the floating display system displays the floating image, so as to ensure that the start of the floating display system is not affected, thereby ensuring the service life of the floating display system; the computing device obtains the self-checking information of the floating display system after the floating display system displays the floating image, so as to ensure that the floating image displayed by the floating display system remains complete and clear during use, thereby providing better user experience.

[0052] The computing device can obtain the above self-checking information through devices in the vehicle, for example, the computing device can obtain the height of the side window glass of the vehicle through a window controller on the vehicle, and the computing device can use a camera to determine whether there is an obstruction in the light transmission path.

[0053] In a possible embodiment, the computing device can detect whether there is an obstruction in the light transmission path through an obstruction self-checking device.

[0054] Please refer to FIG. 2, which is a structural schematic diagram of an obstruction self-checking device provided by the present application. As shown in FIG. 2, the obstruction self-checking device 200 includes a light emitter 201, a half-mirror 202, and a reflected light receiver 203, wherein the light emitter 201 is configured to emit light, the half-mirror 202 is configured to transmit and reflect light, and the reflected light receiver 203 is configured to receive light.

[0055] The working principle of the above obstruction self-checking device 200 includes: placing the half-mirror 202 at a suitable angle so that the light passing through the half-mirror 202 can pass through the above light transmission path; placing the light emitter 201 on one side of the half-mirror 202 and placing the reflected light receiver 203 on the other side of the half-mirror 202; the computing device controls the light emitter 201 to emit light to the half-mirror 202, and the light reaches the half-mirror 202. Due to the characteristics of the half-mirror 202 (half of the incident light is reflected, and half of the incident light is transmitted), part of the light directly transmits through the half-mirror 202, and the light passing through the half-mirror 202 will pass through the above light transmission path. Therefore, when there is an obstruction in the light transmission path, the light passing through the half-mirror 202 will directly contact the obstruction and reflect back. The reflected light reaches the half-mirror 202 again. Due to the characteristics of the half-mirror 202, part of the reflected light is reflected. Since the positions of the half-mirror 202 and the light emitter 201 are fixed, the direction of the reflected light after being reflected by the half-mirror 202 is determined. By placing the reflected light receiver 203 at the direction position in advance, when the reflected light receiver 203 can receive the light emitted by the light emitter 201, it indicates that there is an obstruction in the light transmission path. When the reflected light receiver 203 cannot receive the light emitted by the light emitter 201, it indicates that there is no obstruction in the light transmission path.

[0056] In a possible embodiment, the computing device is further configured to set a threshold of times of finding the existence of the occlusion in the light transmission path within a certain time period, and terminate the current floating display when the times of finding the existence of the occlusion in the light transmission path within the certain time period reaches the threshold. Since the computing device gives a prompt when detecting the existence of the occlusion in the light transmission path, the user can determine the existence of the occlusion in the light transmission path according to the prompt. If the computing device repeatedly detects the existence of the occlusion in the light transmission path, it indicates that the user is most likely not in the vehicle, and the floating display is not needed, so the computing device can turn off the floating display system to save power.

[0057] By setting the threshold of times of finding the existence of the occlusion in the light transmission path within a certain time period, it can be ensured that the computing device and the floating display system do not waste too many resources when the user is not in the vehicle or the prompt function of the computing device fails.

[0058] In S102, the computing device determines whether the self-check information meets a target condition. If the self-check information meets the target condition, the floating display system is controlled to project a floating image in the target area. If the self-check information does not meet the condition for the floating display system to perform floating display, a prompt information is given.

[0059] The target condition is a condition for the floating display system to project a floating image in the target area, and includes:

[0060] Whether there is an occlusion in the light transmission path and whether the side window glass of the vehicle reaches a preset height, wherein the light transmission path is a path for the floating display system to project a floating image in the target area, i.e., a path through which light emitted by a display device in the floating display system passes to finally form a floating image.

[0061] The side window glass of the vehicle reaches the preset height, so that the side window glass of the vehicle can have the function of a mirror, wherein the preset height is the lowest height for the floating display system to project a floating image in the target area through the side window glass of the vehicle. Since the floating display system provided by the present application can be arranged in the side door of the vehicle, the side window glass of the vehicle can be used as a part of the floating display system, thereby reducing the occupation of the floating display system on the internal space of the vehicle. When the floating display system displays a floating image through the side window glass of the vehicle, it is necessary to ensure that the side window glass of the vehicle reaches the preset height, so that the side window glass of the vehicle can have the function of a mirror.

[0062] The computing device determines whether the self-checking information meets the condition for the levitation display system to perform levitation display, for example, the computing device determines whether there is an obstruction in the light transmission path, and in a case where there is an obstruction in the light transmission path, it is determined that the self-checking information does not meet the condition for the levitation display system to perform levitation display; in a case where there is no obstruction in the light transmission path, it is determined that the self-checking information meets the condition for the levitation display system to perform levitation display, and the computing device determines whether the height of the side window glass of the vehicle reaches a preset height, and in a case where the height of the side window glass of the vehicle reaches the preset height, it is determined that the self-checking information meets the condition for the levitation display system to perform levitation display; in a case where the height of the side window glass of the vehicle does not reach the preset height, it is determined that the self-checking information does not meet the condition for the levitation display system to perform levitation display.

[0063] It should be understood that the computing device controls the levitation display system to display the levitation image in the target area only when the self-checking information meets the condition, that is, the computing device controls the levitation display system to display the levitation image in the target area only in a case where there is no obstruction in the light transmission path and the height of the side window glass of the vehicle reaches the preset height, and in a case where the self-checking information does not meet the condition for the levitation display system to perform levitation display, the computing device sends a prompt signal to the user, for example, by sending a prompt sound, a prompt light, etc., and the user can determine that there is an obstruction in the path according to the prompt signal, and the user can remove the obstruction to make the levitation display system display a clear and complete levitation image.

[0064] In a possible embodiment, the computing device controls the levitation display system to display the levitation image in the target area, including: after the levitation display system is turned on, the display device in the levitation display system emits light outward as a light source; the outward emitted light is reflected by the reflector (a certain number of reflectors are arranged around the display device in advance) to the optical element; the outward emitted light of the display device is finally formed into a levitation image in the target area after passing through the optical element or being reflected by the reflector again.

[0065] The optical element can be an equivalent negative refractive index slab lens for converging light passing through the optical element to form a levitation image.

[0066] The display device is used to display an original image corresponding to the levitation image.

[0067] The process of projecting the floating image in the target area by the floating display system is described below in combination with FIG. 3. FIG. 3 is a schematic diagram of light reflection of a floating image according to the present application. As shown in FIG. 3, the floating display system includes a display device 301, a mirror group 302, a side window glass 303 of a vehicle, an optical element 304, a mirror 305, and a side door 306 of the vehicle. The light from a certain point on the display device 301 is reflected by the mirror group 302 and finally reaches the optical element 304. After passing through the optical element 304, the light from the certain point converges in front of the optical element 304 and is reflected by the mirror 305 to the light convergence position (i.e., the target area). Each point on the display device 301 is presented in the target area by the method shown in FIG. 3, and finally a floating image is formed in the target area.

[0068] The display device 301, the mirror group 302, the optical element 304, and the mirror 305 in FIG. 3 can be installed inside the side door 306 of the vehicle, i.e., inside the door corresponding to the side window glass of the vehicle. It should be understood that when the display device 301 and the mirror are installed inside the side door 306 of the vehicle, an opening needs to be provided at the top of the side door 306 so that the light from the display device 301 can be reflected by the mirror 305 to the target area.

[0069] It should be understood that the floating display system in FIG. 3 includes four mirrors and one optical element, and the mirrors and the optical element are arranged in the order of mirror, mirror, optical element, mirror, and mirror according to the path of the light from the display device 301 to the target area. The number and arrangement of the mirrors and the optical element are only examples provided by the present application. In actual situations, more or fewer mirrors and optical elements can be used, and the arrangement of the mirrors and the optical element can also be changed. For example, five mirrors and one optical element can be used, and the mirrors and the optical element can be arranged in the order of mirror, mirror, mirror, mirror, mirror, optical element, and mirror.

[0070] In a possible embodiment, the mirror 305 through which the light passes before the floating image is formed in FIG. 3 is the side window glass of the vehicle, i.e., the side window glass of the vehicle is used as a mirror. In this way, the number of optical elements in the floating display system can be reduced, and the space occupied by the floating display system in the vehicle can be reduced.

[0071] When the above-mentioned mirror 305 is fused with the side window glass of the vehicle as a piece of glass, the side window glass of the vehicle itself is used for the user to observe the outside through the window and for ventilation, but after the side window glass of the vehicle is used to display the floating image, in order to ensure the stability of the floating image, the side window glass cannot be moved in principle, and at this time the side window glass cannot realize the above-mentioned ventilation and observation of the outside. In order to retain the basic function of the side window glass of the vehicle, the side window glass of the vehicle can be divided into a movable part and a fixed part, and the structure of the side window glass can be referred to Figure 4, which is a structural schematic diagram of a side window glass provided by the present application. As shown in Figure 4, the side window glass of the vehicle includes a fixed part and a movable part. After the side window glass of the vehicle is divided into a movable part and a fixed part, the display device in the above-mentioned computing device can display the floating image through the movable part of the side window glass, or display the floating image through the fixed part of the side window glass. When the display device displays the floating image through the movable part of the side window glass, the movable part of the side window glass cannot be moved, and the fixed part of the side window glass does not participate in displaying the floating image, so the user can observe the outside through the fixed part of the side window glass. Similarly, when the display device displays the floating image through the fixed part of the side window glass, the movable part of the side window glass does not participate in displaying the floating image, so the user can observe the outside through the movable part of the side window glass, or open the movable part of the side window glass to realize the function of ventilation.

[0072] In a possible embodiment, the floating display system further includes an atmosphere lamp, and the computing device gives feedback to the user in the form of flashing of the atmosphere lamp when it is determined that the self-checking information does not meet the condition for the floating display system to perform floating display, so that the user obtains information that there may be an occlusion on the light transmission path, or the height of the side window of the vehicle may not be high enough. By giving feedback to the user through the atmosphere lamp in the vehicle, the user's experience can be improved, and when the user turns on the floating display system, the appearance of the floating image can also be emphasized by continuously enhancing the color and brightness of the atmosphere lamp, so that the user realizes that the floating display system has been turned on. Similarly, when the user turns off the floating display system, the closing of the floating display system can be emphasized by continuously weakening the color and brightness of the atmosphere lamp until the color and brightness of the atmosphere lamp completely disappear, so that the user realizes that the floating display system is about to be turned off.

[0073] S103: The computing device obtains operation information of the user.

[0074] The operation information can be a touch track of the user on the floating image, that is, when the user wants to switch the content displayed by the floating image, the user can touch a corresponding area on the floating image to inform the computing device to update the floating image to a corresponding interface. Please refer to FIG. 5, which is a schematic diagram of a user operating a floating image according to the present application. As shown in FIG. 5, the floating image includes a display of weather, date, news, and three buttons of a vehicle function manual, music playing, and e-book browsing. When the user wants to know the function and use scenario of a specific button, the user touches a corresponding area of the button on the floating image. After the computing device detects the operation information of the user, the computing device updates the floating image according to the operation information. For example, assuming that the user wants to view the vehicle function manual, the user can touch a corresponding position of the button of the vehicle function manual on the floating image (as shown in FIG. 5) to inform the computing device to update the content of the floating image to a display of the vehicle function manual. After the computing device determines that the operation information is input on the floating image, the computing device updates the content of the floating image to a display of the vehicle function manual. The operation information includes an operation position and an operation time, the operation position refers to a position touched by the user on the floating image, and the operation time refers to a time during which the user touches the position.

[0075] In a possible embodiment, the computing device determines whether the operation information is input on the floating image by an optical sensor, which can be arranged inside the side door 306 of the vehicle. The optical sensor detects whether the operation information is input on the floating image by infrared rays. After the optical sensor detects the operation information, the optical sensor sends the operation information to the computing device.

[0076] S104: The computing device determines whether the operation information is valid. If the operation information is valid, the computing device controls the floating display system to project a floating image corresponding to the operation information to the target area. If the operation information is not valid, the computing device does not process the floating image.

[0077] After the computing device obtains the operation information, the computing device first determines whether the operation information is valid input. If the operation information is valid input, the computing device determines the content to be displayed by the floating image according to the operation position of the operation information and the control logic of the computing device, and displays the content by the display device and the optical element.

[0078] The computing device determines whether the operation information is valid input in the following manners: 1) determining whether the operation time of the operation information is greater than a preset time. When the operation time of the operation information is greater than the preset time, it is determined that the input of the operation information is invalid. When the operation time of the operation information is less than or equal to the preset time, it is determined that the input of the operation information is valid. 2) determining whether the operation position of the operation information is a valid position. When the operation position of the operation information is a valid position, it is determined that the input of the operation information is valid. When the operation position of the operation information is an invalid position, it is determined that the input of the operation information is invalid.

[0079] When the input time of the operation information is long, it indicates that the input is not intended by the user. For example, when the user accidentally places a hand on a certain position on the floating image, the operation time of the operation information is relatively long.

[0080] When the operation position of the operation information is not a valid position, it indicates that the input does not conform to the operation rules of the interface. For example, when the floating image currently displays a plurality of options including a music option, a video option, and a map option, if the user touches a region other than the three option regions, the computing device determines that the operation position of the operation information is an invalid position.

[0081] The computing device determines that the operation information is valid input only when the operation time of the operation information does not exceed the preset time and the operation position of the operation information is a valid position. By determining the operation time and the operation position of the operation information, the possibility of user misoperation can be reduced to some extent, thereby improving the user experience.

[0082] In a possible embodiment, after displaying the floating image, the computing device further detects whether there is an occlusion in the light transmission path between the display device and the floating display interface of the optical element during the existence of the floating image, to ensure the integrity of the floating image. The process of how the computing device detects whether there is an occlusion in the light transmission path between the display device and the floating display interface of the optical element is described above in relation to S101, and will not be described again here.

[0083] By implementing the above method, the floating display system is arranged in the side door of the vehicle, and the floating image is projected on the target region through the optical element and the mirror. The user's demand for browsing related information can be met. In addition, since the floating display system is arranged in the side door of the vehicle, the floating display system can also reduce the occupation of the internal space of the vehicle, thereby ensuring the user experience. In the above solution, the possibility of misoperation of the floating display system is reduced by determining whether the self-check information of the floating display system meets the condition for the floating display of the floating display system, thereby further improving the user experience.

[0084] In one possible embodiment, the above-mentioned computing device is also part of the aerial display system, and the aerial display imaging method provided by the present application is introduced in the structure of a specific aerial display system. In this embodiment, the domain control is used instead of the above-mentioned computing device. Please refer to FIG. 6, which is a schematic diagram of the structure of an aerial display system provided by the present application. As shown in FIG. 6, the aerial display system includes a domain control, a display device, a window controller, a touch sensor, a side window glass of a vehicle, a shielding self-checking device, and a prompt device, wherein:

[0085] The domain control is the control center of the aerial display system, and is used to receive an opening instruction from a user and to interact with the display device, the window controller, the touch sensor, the shielding self-checking device, and the atmosphere lamp in the aerial display system.

[0086] The display device is used to display the original image of the aerial image. After the display device receives the display instruction from the domain control, the original image displayed by the display device is displayed on the target area through the side window glass of the vehicle.

[0087] The window controller is used to control the height of the side window of the vehicle according to the lifting instruction from the domain control.

[0088] The touch sensor is used to detect whether there is an input of operation information on the aerial image after the aerial image appears, and to send the detected operation information to the domain control.

[0089] The side window glass of the vehicle is integrated with a mirror. The process of how the original image displayed by the display device reaches the target area to form the aerial image is described in the above-mentioned related content in FIG. 3, and will not be described again here.

[0090] The shielding self-checking device is used to detect whether there is an obstruction in the light transmission path between the display device and the aerial image, and to send the information about the existence of the obstruction to the domain control.

[0091] The prompt device includes an atmosphere lamp and a sound, and is used to remind the user that there is an obstruction in the light transmission path between the display device and the aerial image or that the aerial image changes.

[0092] When the aerial display system is used to perform aerial display imaging, the control interaction logic between the components of the aerial display system includes the following steps 1-6.

[0093] Step 1: The user opens the aerial display system.

[0094] When the user needs to use the aerial display function, the user can send an opening instruction to the domain control in the aerial display system through an external device (for example, an external switch and a central control screen).

[0095] After the domain control receives the start instruction, the floating display system starts to start and executes step 2.

[0096] Step 2, the floating display system detects whether there is an obstruction in the light transmission path between the display device and the floating image.

[0097] The obstruction self-checking device detects whether there is an obstruction in the light transmission path between the display device and the floating image after the floating display system starts, and sends the information that there is an obstruction to the domain control. After the domain control receives the information that there is an obstruction, the domain control sends a start instruction to the prompt device (ambient light and sound) to remind the user that there is an obstruction in the light transmission path between the display device and the floating image. After the domain control receives the information that there is an obstruction for a certain period of time, the domain control terminates the display of the floating image and shuts down the floating display system.

[0098] The above description of how the obstruction self-checking device detects whether there is an obstruction in the light transmission path between the display device and the floating image can be referred to the related description in the above-mentioned FIG. 2, which will not be described in detail here.

[0099] After the domain control determines that there is no obstruction in the light transmission path between the display device and the floating image, the floating display system executes step 3.

[0100] Step 3, the floating display system controls the side window glass of the vehicle to rise to a preset height.

[0101] The domain control sends a lifting instruction to the window controller, and the window controller first judges whether the height of the current vehicle window meets the display requirements of the floating image after receiving the lifting instruction. If the height of the vehicle window does not meet the display requirements of the floating image, the window controller controls the vehicle window to rise to a preset height and sends the information that the height of the vehicle window has met the display requirements of the floating image to the domain control. If the height of the vehicle window has met the display requirements of the floating image, the window controller sends the information that the height of the vehicle window has met the display requirements of the floating image to the domain control.

[0102] After the domain control receives the information that the height of the vehicle window has met the display requirements of the floating image, the floating display system executes step 4.

[0103] Step 4, the floating display system displays the floating image through the side window glass of the vehicle.

[0104] The domain control sends a display instruction to the display device, and the display device displays the floating image to the target area through the side window glass of the vehicle after receiving the display instruction.

[0105] The above description about how the display device displays the levitation image to the target area through the side window glass of the vehicle can be referred to the description of the related part in the above Figure 3, and will not be described here.

[0106] Step 5, the levitation display system detects whether there is operation information on the levitation image.

[0107] The touch sensor detects whether there is operation information input on the levitation image after the levitation image is displayed, and sends the operation information to the domain control in the case that there is operation information input.

[0108] The domain control judges whether the operation information meets the preset rule after receiving the operation information, and the levitation display system performs step 6 in the case that it is determined that the operation information meets the preset rule.

[0109] The above domain control judging whether the operation information meets the preset rule includes whether the operation time of the operation information meets the preset rule and whether the operation position of the operation information meets the preset rule. The detailed description about whether the operation information meets the preset rule can be referred to the related content in the above Figure 1, and will not be described here.

[0110] Step 6, the levitation display system updates the content of the levitation image according to the operation information.

[0111] The domain control determines the content of the levitation image according to the operation information, and sends a new display instruction to the display device, and the display device updates the content of the levitation image according to the new display instruction.

[0112] In the above levitation display system, the display device displays the levitation image to the target area through the optical element arranged on the side door of the vehicle, which can meet the demand of the rear-row user to browse related information, and in the above scheme, whether there is an occlusion on the light transmission path between the display device and the levitation image is judged through the occlusion self-checking device, which can reduce the possibility of misoperation of the levitation display system, so as to ensure the integrity and clarity of the levitation image.
