Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a display method, device, vehicle, electronic equipment and storage medium. Background Art

[0002] The head-up display (HUD) can project various information and images onto the windshield in front of the driver, allowing the driver to obtain information such as vehicle speed, navigation, safety tips, entertainment and life information without having to look down at the dashboard or the car screen. This can not only improve driving safety, but also increase driving pleasure.

[0003] The field of view (FOV) of the head-up display determines the coverage of its imaging screen, and thus determines the display information presented. The larger the field of view of the head-up display, the larger the coverage of the imaging screen, and the more display information can be displayed. However, the larger the field of view of the head-up display, the more difficult its process is. During design, if the display of road information meets the requirement of not blocking the road surface, the lateral FOV needs to be set wider, which is difficult to meet with existing processes. Therefore, existing head-up displays usually give priority to presenting the most important information on the head-up display while maintaining the existing FOV, and less important information is displayed. When users need to view less important information, they need to manually control it to be displayed, which still affects the driving safety of the vehicle. Summary of the invention

[0051] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0052] Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in a variety of ways with substantially any suitable detailed structure.

[0053] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0054] Figure 1 The imaging principle diagram of the head-up display is shown in FIG. Figure 1As shown, the image source (head-up display 200) can emit imaging light to the imaging area of ​​the windshield 100. The imaging light is reflected by the imaging area of ​​the windshield 100 and then propagates to the eye box area, so that the user can see the imaging picture (for example, a virtual image) through the imaging area.

[0055] The eye box area refers to the area where the eyes of an observer (such as a driver, passenger and / or other user) are located and can observe the image formed by the head-up display. The observer can see the formed image at different positions of the eyes in the eye box area.

[0056] Figure 2 A flow chart showing a display method according to an embodiment of the present disclosure is shown; Figure 3 and Figure 4 FIG. 2 shows a schematic diagram of displaying the first information and the second information of an embodiment of the present disclosure. Figures 2 to 4 As shown, the embodiment of the present disclosure provides a display method, including:

[0057] S101: Displaying first information on a first head-up display; and

[0058] S102: Displaying second information on a second head-up display, wherein the first head-up display is an AR-HUD, the second head-up display is a non-AR-HUD, and a second imaging screen of the second head-up display is located below a first imaging screen of the first head-up display.

[0059] The first head-up display is an AR-HUD (Augmented Reality Head Up Display), which can superimpose the display information in the virtual image formed by the reflection of the windshield with the real scene in front of the vehicle, for example, the display information is enhanced to fit the actual road, and provide the driver with clearer and more intuitive information guidance. The display information of the first head-up display may include information related to vehicle driving, such as instrument information, safety auxiliary prompt information, ADAS information, and navigation information, and may also include entertainment life information (such as video call information, weather, etc.) and other information unrelated to vehicle driving. In this embodiment, the display information of the first head-up display can be divided into two categories of information, namely, information unrelated to road fitting (such as instrument information such as vehicle speed, entertainment life information) and information related to road fitting (such as navigation information), according to whether it fits the real scene (such as the road). Information unrelated to the road, that is, this type of information does not need to be fused with the real scene (or called superposition) through augmented reality technology when displayed; information related to the road, that is, this type of information needs to be fused with the real scene (or called superposition) through augmented reality technology when displayed.

[0060] The second head-up display is a non-AR-HUD (non-augmented reality head-up display), for example, it may be a P-HUD (Panoramic HUD, panoramic head-up display).

[0061] The display information of the second head-up display can also include instrument information, safety assistance prompt information, ADAS information, navigation information, and entertainment life information.

[0062] Since the first head-up display has a wider field of view than other head-up displays and can display more information, the first head-up display is used as the main display, and the first image formed by its imaging is the main image, and the second head-up display is used as the auxiliary display, and the second image formed by its imaging is the auxiliary image. The second image is located below the first image, which means that the second information is located below the first information, so that the user can view the second information located below the first information while viewing the first information, that is, different display information can be presented simultaneously through different head-up displays, and more information can be displayed, which is convenient for users to view. At the same time, the first head-up display can achieve an enhanced display effect of the displayed information, thereby improving the user's visual experience.

[0063] The second imaging screen of the second head-up display is located below the first imaging screen of the first head-up display. For example, part or all of the second imaging screen is located below the first imaging screen (for example, directly below, lower left, or lower right), part of the second imaging screen is located at the lower left of the first imaging screen, part of the second imaging screen is located directly below the first imaging screen, and the rest of the second imaging screen is located directly below the first imaging screen, etc.

[0064] In particular, since the information related to road conformity in the first head-up display is usually displayed on the upper part of the windshield, while the information unrelated to road conformity is displayed on the lower part of the windshield, the second imaging screen is projected above the vehicle's dashboard (IP platform) to display the second information above the vehicle's dashboard, thereby expanding the information display space in front of the driver without affecting the user's viewing of information related to road conformity, thereby ensuring the user's visual experience.

[0065] In this embodiment, the first information and the second information may be different. For example, the first information is the display information in front of the vehicle, and the second information is the electronic rearview mirror information (including rearview mirror image and rearview mirror prompt information), so that the user can view the road conditions in front and behind the vehicle at the same time.

[0066] The first information and the second information may also be partially the same. For example, the first information is point of interest (POI) information, and the second information is magnified information of the point of interest information. When the first head-up display displays too much information, the point of interest information is displayed in the second head-up display for easy viewing.

[0067] The display method provided by the embodiment of the present disclosure displays the first information on the first head-up display and the second information on the second head-up display, wherein the first head-up display is an AR-HUD, the second head-up display is a non-AR-HUD, and the second imaging screen of the second head-up display is located below the first imaging screen of the first head-up display. The first head-up display and the second head-up display can be used to display more and more comprehensive information, thereby improving driving safety and ensuring the user's visual experience.

[0068] In some embodiments, before executing step S102, displaying the second information on the second head-up display, the method further includes:

[0069] S201: Determine whether the second information is information of a preset type, wherein the preset type of information includes at least one of electronic rearview mirror (Camera Monitor System, CMS for short) information, multimedia interaction information, detailed information of points of interest, and map information;

[0070] S202: If yes, display the second information on the second head-up display.

[0071] In this embodiment, the second information can be displayed on the second head-up display according to its type. For example, when the second information is electronic rearview mirror information, it can be displayed on the second head-up display so that the user can view the environmental information behind the vehicle and determine whether there is a reversing blind spot, etc. At this time, the first information displayed on the first head-up display can be used to view the environmental information in front of the vehicle and determine whether there are pedestrians or other vehicles passing in front of the vehicle to achieve safe reversing.

[0072] When the second information is multimedia interactive information such as music playback, video calls, etc., the multimedia interactive information can be directly displayed on the second head-up display, making it convenient for users to look directly in front of the vehicle to view lyrics or make video calls, etc., without having to lower their heads to look at the car screen or mobile phone, thereby improving the multimedia experience during driving or riding and further improving the driver's driving safety.

[0073] In addition, in this embodiment, the first information and the second information are displayed on the first head-up display and the second head-up display respectively according to their types, which can avoid the second information being displayed on the first display blocking the first information currently displayed on the first display and affecting driving safety.

[0074] Optionally, the multimedia interactive information can also be the image information of the rear seats. In this case, the front-seat users (including the driver and the front passenger) can look directly in front of the vehicle and view the information of special passengers such as rear-seat child passengers or deaf-mute passengers through the image information of the rear seats displayed on the second head-up display, interact with special passengers, improve the interactive experience, and avoid safety accidents. For example, when a deaf-mute passenger needs to get off the vehicle, the vehicle can be stopped in time through the gesture of the deaf-mute passenger displayed in the second head-up display, without the driver turning his head to check, thus maintaining the driver's driving safety; for another example, the image of the child can be viewed in time through the second head-up display, and prompts can be given in time when the child accidentally eats food, thus avoiding safety accidents caused by the child being unable to open his mouth due to accidental ingestion.

[0075] In this embodiment, Figure 3 and Figure 4 As shown, the first head-up display corresponds to the first imaging area 1001 on the windshield, and the second head-up display corresponds to the second imaging area 1002 on the windshield. The image light emitted by the first head-up display is incident on the first imaging area 1001, and the image light emitted by the second head-up display is incident on the second imaging area 1002. The first imaging area 1001 is located above the second imaging area 1002.

[0076] according to Figure 1 The imaging principle of the head-up display shown in the figure is that the head-up display 200 needs to project the emitted image light into the corresponding imaging area on the windshield 100 to form the corresponding imaging picture, so that the user can view the imaging picture in the imaging area. Therefore, in this embodiment, the windshield is divided into a first imaging area 1001 corresponding to the first head-up display and a second imaging area 1002 corresponding to the second head-up display, and in order to make the first imaging picture of the first head-up display located above the second imaging picture of the second head-up display, the first imaging area is set above the second imaging area. The first imaging area occupies most of the imaging area of ​​the windshield.

[0077] Optionally, the first imaging area and the second imaging area may not overlap at all, so that the first imaging screen and the second imaging screen viewed by the user do not overlap. The first imaging area and the second imaging area may also overlap partially, so that the lower part of the first imaging screen and the upper part of the second imaging screen overlap to a certain extent, so that when the size of the windshield is limited, the second information 302 is moved up so that the second information 302 is within the user's better line of sight, and there is no need to lean forward to view the second information 302 located below the first imaging screen near the dashboard. For example, Figure 4As shown, when the first information displayed in the lower part of the first imaging area is the instrument information 3011, the first imaging area 1001 can be partially overlapped with the second imaging area 1002 (there is an overlapping area 1003 between the two imaging areas), so that the second information 302 is displayed on the left and right sides of the instrument information 3011, which is convenient for users to view and does not affect the display of other information in the first information (such as navigation information 3012 that fits the road) in the first head-up display.

[0078] In some embodiments, Figure 3 and Figure 4 As shown, the second imaging screen at least includes a first display area and a second display area located on the left and right sides of the first imaging screen. In step S202, displaying the second information on the second head-up display includes:

[0079] S301: displaying the second information in the first display area and / or the second display area; and / or

[0080] S302: According to the display priority of the second information and the display priority of the information currently displayed in the first display area and the second display area, replace the information currently displayed in the first display area and / or the second display area with the second information.

[0081] In this embodiment, a first display area 401 and a second display area 402 for displaying the second information 302 can be set on the left and right sides of the first imaging screen, respectively corresponding to the driver's seat and the co-pilot seat, so as to facilitate the driver and the co-pilot passenger to view the second information 302.

[0082] For example, the first CMS information (for example, the CMS information collected by the left electronic rearview mirror) can be displayed in the first display area 401 on the left side of the first imaging screen (corresponding to the driver's seat), and the second CMS information (for example, the CMS information collected by the right electronic rearview mirror) can be displayed in the second display area 402 on the right side of the first imaging screen (corresponding to the co-pilot seat), so as to facilitate the viewing of the CMS information collected by the left and right electronic rearview mirrors.

[0083] When the passenger in the front passenger seat makes a video call, the video call information may be displayed only in the second display area 402, which facilitates the front passenger seat to make the video call while avoiding the video call information being displayed in the first display area to distract the driver and improve driving safety.

[0084] In other embodiments, when the display priority of the second information is higher than the display priority of the information currently displayed in the first display area and the second display area, for example, the second information is CMS information, and the display priority of the information currently displayed in the first display area and the second display area is weather information and other information with lower priority, the CMS information can be replaced and displayed in the first display area 401 or the second display area 402. For example, the CMS information can be replaced and displayed in the first display area 401, while the weather information can be retained and displayed in the second display area 402, so as to meet the different viewing needs of users.

[0085] When both first display area 401 and second display area 402 have high-priority second information, the low-priority information currently displayed in first display area 401 and second display area 402 may be hidden, and then the second information may be displayed in first display area 401 and second display area 402 instead.

[0086] It is understandable that the vehicle virtual assistant, weather, time and other information can be used as low-priority default information and always displayed in the first display area 401 and / or the second display area 402 of the second head-up display, and CMS information (information required for turning or reversing), video call information and the like can be used as high-priority second information and displayed in the first display area 401 and / or the second display area 402 of the second head-up display after the rearview mirror system is started or the video call is triggered, that is, the second information is temporary information displayed according to actual needs during the driving process of the vehicle, and is displayed in the first display area 401 and / or the second display area 402 for a short time (or for a period of time). The above-mentioned CMS information can also be used as permanent display information and displayed in the first display area 401 and / or the second display area 402 for a long time after the vehicle is started.

[0087] In some embodiments, Figure 3 As shown, the second imaging screen of the second head-up display further includes a third display area 403 located below the first imaging screen, and the third display area 403 is located between the first display area 401 and the second display area 402. In step S202, displaying the second information on the second head-up display includes:

[0088] S401: Displaying the second information in the third display area 403; and / or

[0089] S402: Switching the second information from the third display area 403 to the first display area 401 and / or the second display area 402 for display.

[0090] In this embodiment, the display area (imaging area) corresponding to the second imaging screen can be divided into three display areas: left, middle, and right, to display different second information respectively to meet different display requirements. For example, CMS information can be displayed in the first display area 401 and the second display area 402 on the left and right sides, and the vehicle instrument information 3011 can be displayed in the third display area 403 in the middle (at this time, the instrument information 3011 is displayed in the third display area 403 as the second information 302). For another example, when the second information is map information, since the intersection information is usually displayed in the center of the first imaging area in the first information displayed on the first head-up display, the map information associated with the above intersection information can be displayed in the third display area 403 located in the middle position to match the first information, so as to facilitate the user to view. At the same time, when necessary, for example, when the distance to the intersection is close, the map information displayed in the third display area 403 can be switched to the first display area 401 and / or the second display area 402 through step S402, which is convenient for users to view the road conditions at the intersection and to understand the map information corresponding to the intersection, thereby improving the user's HUD usage experience.

[0091] In a specific embodiment, the second information is electronic rearview mirror information, and in step S202, displaying the second information on the second head-up display includes:

[0092] S501: Acquire the electronic rearview mirror signal of the vehicle;

[0093] S502: after detecting that the turn signal of the vehicle is turned on, displaying corresponding electronic rearview mirror information in the first display area and / or the second display area according to the electronic rearview mirror signal; or

[0094] S503: Acquire the positioning signal of the vehicle;

[0095] S504: When it is detected according to the positioning signal that the vehicle is approaching a turning intersection, corresponding electronic rearview mirror information is displayed in the first display area and / or the second display area according to the electronic rearview mirror signal.

[0096] In this embodiment, the display of the second information can be triggered by detecting the current state of the vehicle, that is, triggered by interaction with the vehicle control system (for example, the vehicle control system VCU). The controller of the second head-up display can obtain the electronic rearview mirror signal sent by the vehicle control system in real time. When it is detected that the turn signal is on, the electronic rearview mirror information collected by the rearview mirror camera is displayed in the first display area 401 and / or the second display area 402, so that the user can view the road condition information behind the vehicle conveniently.

[0097] In some other embodiments, the controller of the second head-up display can also obtain the real-time positioning signal of the vehicle through the vehicle control system that communicates with the vehicle navigation system when the vehicle navigation system is turned on, and determine whether the vehicle is traveling to a position close to a turning intersection. If so, based on the electronic rearview mirror signal obtained in step S501, the corresponding electronic rearview mirror information is displayed in advance in the first display area 401 and / or the second display area 402, so as to facilitate the user to observe the road conditions in time when turning.

[0098] In a specific implementation, the display of the second information can also be triggered by interaction with the vehicle system. For example, when the user chooses to answer a video call on the vehicle system or makes a video call, the video call screen can be projected and displayed in the first display area 401 and / or the second display area 402, providing a viewing space that is closer to the driver's line of sight and does not block the road surface.

[0099] In some embodiments, the first information is brief information of the point of interest, and the second information is detailed information of the point of interest. In step S202, displaying the second information on the second head-up display includes:

[0100] S601: Based on an operation on first information displayed on the first head-up display, display the second information in the first display area and / or the second display area.

[0101] In this embodiment, the display of the second information can be triggered based on the display of the first information, that is, triggered by interaction with the first head-up display. The point of interest information displayed on the first head-up display is brief information of the point of interest such as the POI icon and name. At this time, the user can perform corresponding selection operations on the point of interest. After receiving the selection operation signal, the controller of the second head-up display can display the detailed information of the point of interest in the first display area 401 and / or the second display area 402, so that the user can understand the point of interest in more detail, and can effectively avoid the problem of insufficient display content of the first head-up display. In particular, when the detailed information of the point of interest is displayed, it can be continuously displayed for a preset time so that the passenger in the front passenger seat or the rear passenger can view the information. For example, when the point of interest is a shopping mall, the passenger in the front passenger seat or the rear passenger can find the restaurant or brand in it according to the detailed information of the shopping mall, so as to facilitate the subsequent quick arrival at the restaurant or brand store after arriving at the shopping mall.
