Abstract
Description
Technical Field
[0001] The present invention relates to the field of vehicle-mounted equipment control, and in particular to a control method and device for a vehicle-mounted display device and a vehicle-mounted display system. Background Art
[0002] With the development and maturity of the automobile industry, the driver-centric design concept has been proposed. Under the guidance of this design concept, the comfort and driving experience of automobiles are getting better and better. For example, under the guidance of this design concept, the Head Up Display (HUD) system has been introduced into automobile design.
[0003] The head-up display system is also called the "head-up display system". Generally, it projects the relevant information of the vehicle onto the optical imaging system in front of the driver's field of vision through an image generation unit, so that the driver can read important driving information such as speed and navigation without looking down at the dashboard. Compared with the traditional dashboard, the HUD system reduces the frequency of the driver lowering his head and turning his head, improving driving safety.
[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present invention and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because these solutions are described in the background technology section of the present invention. Summary of the invention
[0005] In the prior art, when designing the styling of a car, the position and height of the display interface of the HUD system is usually determined based on the line of sight of most users. After purchasing a car, consumers manually adjust the HUD system according to their own line of sight and habits.
[0006] The inventors found that a car is usually equipped with a dashboard. In order to facilitate reading of the information displayed by the HUD system and the information on the dashboard, the display interface of the HUD system can be adjusted to a position adjacent to the display interface of the dashboard during design. For example, the display interface of the HUD system can be adjusted above the display interface of the dashboard. However, when the user's line of sight changes, sometimes the display interface of the dashboard will block part of the information on the display interface of the HUD system, affecting the user's acquisition of driving information. Sometimes there is a large gap between the display interface of the HUD system and the display interface of the dashboard, resulting in a poor user experience. In order to avoid blocking information or creating a gap, the height of the HUD system needs to be manually adjusted, and manual adjustment of the HUD system takes a long time and has low accuracy. In addition, after the user's line of sight changes, when observing the dashboard, problems such as glare, visual fatigue, and reduced reading accuracy may occur, which reduces the driving experience.

[0054] With reference to the accompanying drawings, the above and other features of the present invention will become apparent through the following description. In the description and the accompanying drawings, specific embodiments of the present invention are specifically disclosed, which show some embodiments in which the principles of the present invention can be adopted, and it should be understood that the present invention is not limited to the described embodiments, but includes all modifications and equivalents falling within the scope of the attached claims.
[0055] The control method and device of the vehicle-mounted display device and the vehicle-mounted display system according to the embodiments of the present invention are described below with reference to the accompanying drawings.
[0056] Example 1
[0057] Embodiment 1 of the present invention provides a method for controlling a vehicle-mounted display device. The vehicle-mounted display device, for example, includes two display devices, namely, a first display device and a second display device. Figure 1 FIG. 1 is a flow chart of a control method of a vehicle-mounted display device according to Embodiment 1 of the present invention. Figure 1 As shown, the control method 100 includes:
[0058] Step 101, collecting the user's sight direction;
[0059] Step 102, determining the sight point according to the sight direction and the relative position relationship between the display interface of the first display device and / or the second display device and the user;
[0060] Step 103, when the line of sight is located within a predetermined area in the display interface of the first display device and / or the second display device, adjust the position and / or angle of the display interface of the first display device and / or the second display device in space so that the display interface of the first display device and the display interface of the second display device are continuous when observed from the line of sight.
[0061] Thus, the display interfaces of the two display devices are adjusted according to the user's line of sight, so that the two display interfaces are continuous when observed from the user's line of sight. Therefore, it is convenient for the user to obtain driving information and reduce visual fatigue.
[0062] In step 101, the user's line of sight direction can be collected based on the user's facial image. For example, the collected facial image is analyzed based on a neural network model to obtain the user's line of sight direction and head posture, and the line of sight direction is obtained based on the line of sight direction and head posture. Other methods can also be used to collect the user's line of sight direction. For details, reference can be made to related technologies. The embodiments of this application do not limit the implementation method of how to collect the user's line of sight direction.
[0063] In addition, in an embodiment of the present invention, the user may be a driver in a driving position, and thus, the display interface may be adjusted according to the driver's line of sight, so that it is convenient for the driver to obtain driving-related information. However, the embodiment of the present invention is not limited thereto, and the user may also be other personnel in the vehicle, thereby facilitating other personnel in the vehicle to obtain driving information. The control method of an embodiment of the present invention is described below by taking the adjustment of the display interface according to the driver's line of sight as an example, but those skilled in the art should understand that the control method of an embodiment of the present invention is also applicable to adjusting the display interface according to the line of sight of other personnel in the vehicle.
[0064] Figure 2 It is a schematic diagram of determining the sight point according to Embodiment 1 of the present invention.
[0065] like Figure 2 As shown, the display interface 201 of the first display device 10 is located below the display interface 202 of the second display device 20, and the line of sight directions of the driver D are represented by E1, E2, and E3. For example, the line of sight direction E1 is toward the display interface 201, the line of sight direction E2 is toward the display interface 202, and the line of sight direction E3 is toward the boundary between the display interface 201 and the display interface 202.
[0066] In step 102, the sight point P1 of the driver D can be calculated according to the sight direction E1, the distance S1 from the driver D to the display interface 201 and other parameters; or the sight point P2 of the driver D can be calculated according to the sight direction E2, the distance S2 from the driver D to the display interface 202 and other parameters; or the sight point of the sight direction E3 can be calculated according to the sight direction E3, the distance S1 from the driver D to the display interface 201, the distance S2 from the driver D to the display interface 202 and other parameters, and the sight point may be located on the display interface 201 or on the display interface 202. In addition, in the embodiment of the present invention, for the convenience of explanation, the relative position relationship between the display interface and the user is explained by taking the distance between the display interface and the user as an example, but the embodiment of the present invention is not limited thereto, and the relative position relationship between the display interface and the user may include the distance between the display interface and the user, and may also include the height difference between the display interface and the user's eyes, which is not limited in the embodiment of the present invention.
[0067] In the embodiment of the present invention, the sight point is not limited to a point, but can also be a visible area, for example, an area in the field of vision where effective information can be received after the human eye focuses. The determination of this area can refer to the relevant technology, and the embodiment of the present invention does not limit this. In addition, when the sight point is a visible area, for example, it can be determined whether the sight point falls on the area by judging the ratio of the overlapping area between the visible area and a region to the area of the visible area and the size of the threshold. For example, if the overlapping area between the visible area of the sight point and a certain area accounts for more than 50% of the area of the visible area, it means that the sight point is located in the area. For example, the overlapping area between the visible area of the sight point and the display interface of the display device is judged. When the overlapping area accounts for more than 50% of the area of the visible area, it is considered that the sight point is located on the display interface. In addition, the threshold can be 70% or other ratios, and the embodiment of the present invention does not limit this. In addition, other methods can also be used to determine the position of the sight point, and the embodiment of the present invention does not limit this.
[0068] in addition, Figure 2 The first display device 10 and the second display device 20 are only schematic diagrams. The display interface 201 of the first display device 10 can be formed as one body with the main body of the first display device 10, or can be formed as a separate body. The display interface 202 of the second display device 20 can be formed as one body with the main body of the second display device 20, or can be formed as a separate body. For example, the first display device 10 can be an instrument panel, and the second display device 20 can be a head-up display device. The first display device 10 and the second display device 20 can also be other vehicle-mounted display devices, which is not limited in the embodiments of the present invention.
[0069] The above description is made by taking the display interface 201 and the display interface 202 as an example of being distributed vertically, but the embodiment of the present invention is not limited thereto, and the display interface 201 and the display interface 202 may also be distributed horizontally. The following description is made by taking the display interface 201 and the display interface 202 as an example of being distributed vertically to describe various implementations of the embodiment of the present invention, but those skilled in the art should understand that various implementations of the embodiment of the present invention are also applicable to the case where the display interface 201 and the display interface 202 are distributed horizontally.
[0070] Figure 3 is a schematic diagram for explaining the predetermined area of Embodiment 1 of the present invention, Figure 3 The diagram shows a situation where the display interface 201 and the display interface 202 are vertically distributed as viewed from the user's perspective.
[0071] In some embodiments, the predetermined area includes an area within a first predetermined height from an upper edge in the display interface of the first display device, and / or an area within a second predetermined height from a lower edge in the display interface of the second display device.
[0072] like Figure 3 As shown in (a), the predetermined area may include, for example, an area A1 within a predetermined height H1 from the upper edge in the display interface 201 of the first display device, or may include an area A2 within a predetermined height H2 from the lower edge in the display interface 202 of the second display device. When the line of sight is located in area A1 or area A2, it is considered that the line of sight is located in the predetermined area. The size of H1 and H2 can be arbitrary, for example, it can be determined according to the size of the two display interfaces, or it can be customized by the user, and the embodiment of the present application is not limited to this. The user's line of sight falls within the predetermined area, indicating that the user is interested in the display information within the predetermined area. Since the predetermined area is located near the junction of the two display interfaces, it is easy to be blocked by the display interfaces when the user's line of sight changes slightly. Therefore, when the user's line of sight falls within the predetermined area, by adjusting the position and / or angle of at least one of the two display interfaces in space, it is convenient for the user to obtain the information of interest.
[0073] In the embodiment of the present invention, the so-called “two display interfaces are continuous when observed from the line of sight” means that when the two display interfaces are observed from the line of sight, the adjacent edges of the two display interfaces are overlapped but not overlapped. In other words, the adjacent edges of the two display interfaces are connected. Figure 3 As shown in (b), when observed from the user's perspective, the lower edge of the display interface 202 is connected to the upper edge of the display interface 201, that is, when observed from the line of sight, the display interface 202 and the display interface 201 are continuous.
[0074] In the case where the two display interfaces are continuous, the predetermined area may also be an area near the overlapping edge m of the two display interfaces, for example, Figure 3 As shown in (b), the height of the upper edge of the predetermined area A from the overlapping edge m is H4, and the height of the lower edge of the predetermined area A from the overlapping edge a is H3. The sizes of H3 and H4 can be arbitrary, for example, they can be determined according to the sizes of the two display interfaces, or they can be customized by the user. In addition, the width of the predetermined area A can also be arbitrary, for example, they can be determined according to the sizes of the two display interfaces, or they can be customized by the user. The embodiments of the present application are not limited to this. In addition, when the two display interfaces are distributed horizontally, the predetermined area can be an area within a predetermined width from the edges of the left and right sides of the two display interfaces. The implementation method is similar to the implementation method when the two display interfaces are distributed vertically, and will not be described one by one here.
[0075] In the embodiment of the present invention, the predetermined area may also include an area on the display interface of the two display devices where specific content is displayed, and the specific content is, for example, content with continuity. For example, the predetermined area includes an area on the display interface of the first display device where continuous content is displayed and / or an area on the display interface of the second display device where continuous content is displayed.
[0076] In actual scenarios, the information that needs to be prompted can be displayed in the display interface in the form of text or in the form of pictures. Sometimes, when the text information is large or the size of the picture information is large, displaying it only through one display interface may make the text or picture small or blurry, which is not conducive to users obtaining the information.
[0077] The control method of the embodiment of the present invention can enable two display interfaces to display content with continuity, for example, Figure 3 As shown in (a), continuous content can be displayed on display interface 201 and display interface 202 according to the user's reading habits, for example, displaying according to the reading habit from top to bottom. In addition, for a horizontally distributed display interface, for example, it can be displayed according to the reading habit from left to right. In addition, one or more pictures can be displayed on display interface 201 and display interface 202. In addition, part of a navigation interface or other interface can be displayed on display interface 201, and another part can be displayed on display interface 202, etc. The embodiment of the present invention does not limit this.
[0078] In the embodiment of the present invention, when the user's sight point falls within the predetermined area, the position and / or angle of the display interface of the first display device and / or the second display device in space are adjusted so that the two display interfaces are continuous when observed from the sight direction. This makes it convenient for the user to obtain continuity information.
[0079] In this way, by limiting the predetermined area, the position and / or angle of the display interface of the first display device and / or the second display device in space can be adjusted more accurately based on the user's line of sight, which is beneficial to improving the user's driving experience.
[0080] In an embodiment of the present invention, in step 103, the position and / or angle of the display interface of the display device in space is adjusted. For example, the direction parallel to the direction of travel of the vehicle is referred to as the "front-rear direction", the direction parallel to the vertical direction is referred to as the "up-down direction", and the direction perpendicular to the front-rear direction and the up-down direction is referred to as the "left-right direction". The position of the display interface in space includes the position in the front-rear direction, the height in the up-down direction, and the position in the left-right direction. The angles of the display interface in space include spatial angles such as the pitch angle relative to the front-rear direction. In the absence of ambiguity, for the convenience of explanation, the position and / or angle of the display interface in space is sometimes referred to as the spatial posture of the display interface, unless otherwise specified.
[0081] Figure 4 is another flow chart of the control method of the vehicle-mounted display device of embodiment 1 of the present invention, Figure 4 An implementation of step 103 is described.
[0082] like Figure 4 As shown, step 103 may include:
[0083] Step 1031: adjusting the position and / or angle of the display interface of the first display device in space according to the sight line direction and the relative position relationship between the display interface of the first display device and the user;
[0084] Step 1032: Adjust the position and / or angle of the display interface of the second display device in space according to the line of sight direction, the relative position relationship between the display interface of the second display device and the user, and the position and / or angle of the display interface of the first display device in space, so that when observed from the line of sight direction, the display interface of the first display device and the display interface of the second display device are continuous.
[0085] For example, Figure 2As shown, assuming that the user's line of sight direction is the direction shown by E3, the spatial posture of the display interface 201 can be adjusted first according to the user's line of sight direction E3 and the distance S1 between the display interface 201 and the user (for example, the driver D). The first display device 10 is, for example, an instrument panel, and the instrument panel can be driven to move and / or rotate by a driving mechanism, thereby adjusting the spatial posture of the display interface of the instrument panel; then, the spatial posture of the display interface 202 is adjusted according to the line of sight direction E3, the distance S2 between the display interface 202 and the driver D, and the spatial posture of the display interface 201. The second display device 20 is, for example, a projection display device, and the projection position and angle can be adjusted by adjusting the optical imaging system in the second display device 20, thereby adjusting the spatial posture of the display interface 202. For specific methods of adjusting the spatial posture of the display interface of the display device, reference can be made to the relevant technology, which will not be described one by one here.
[0086] Figure 5 is another flow chart of the control method of the vehicle-mounted display device of embodiment 1 of the present invention, Figure 5 Another implementation of step 103 is described.
[0087] like Figure 5 As shown, step 103 may include:
[0088] Step 1031': adjusting the position and / or angle of the display interface of the second display device in space according to the sight line direction and the relative position relationship between the display interface of the second display device and the user;
[0089] Step 1032': Adjust the position and / or angle of the display interface of the first display device in space according to the line of sight direction, the relative position relationship between the display interface of the first display device and the user, and the position and / or angle of the display interface of the second display device in space, so that when observed from the line of sight direction, the display interface of the first display device and the display interface of the second display device are continuous.
[0090] For example, Figure 1 As shown, assuming that the user's line of sight direction is the direction shown by E3, the spatial posture of the display interface 202 can be adjusted first according to the user's line of sight direction E3 and the distance S2 between the display interface 202 and the user (for example, the driver D), and then the spatial posture of the display interface 201 can be adjusted according to the line of sight direction E3, the distance S1 between the display interface 201 and the driver D, and the spatial posture of the display interface 202. The implementation method of adjusting the spatial posture of the display interface can be similar to the above implementation method, and can also refer to the relevant technology, which is not limited in the embodiment of the present invention.
[0091] In this way, by first adjusting the display interface of one display device to a posture suitable for user viewing, and then adjusting the display interface of another display device to a position continuous with the display interface of the one display device, the display interface posture adjustment can be easily achieved.
[0092] In addition, the two interfaces can also be adjusted in linkage at the same time.
[0093] Figure 6 is another flow chart of the control method of the vehicle-mounted display device of embodiment 1 of the present invention, Figure 6 Another implementation of step 103 is described.
[0094] like Figure 6 As shown, step 103 may include:
[0095] Step 1031": adjust the position and / or angle of the display interface of the first display device in space and the position and / or angle of the display interface of the second display device in space according to the line of sight direction, the relative position relationship between the display interface of the first display device and the user, and the relative position relationship between the display interface of the second display device and the user, so that when observed from the line of sight direction, the display interface of the first display device and the display interface of the second display device are continuous.
[0096] For example, Figure 1 As shown, assuming that the user's line of sight is the direction shown by E2, the line of sight E2, the distance S1 between the display interface 201 and the user (for example, the driver D), and the distance S2 between the display interface 202 and the user (for example, the driver D) can be determined to determine the distance that the upper edge of the display interface 201 moves upward when viewed from the line of sight E2, the pitch angle of the display interface 201 after the display interface 201 moves the distance suitable for the driver D to obtain the information on the display interface 201, and the distance that the lower edge of the display interface 202 moves upward. Then, the corresponding driving mechanism is driven according to the determined parameters to move the display interface 201 and the display interface 202 to a position where the display interface 201 and the display interface 202 are continuous when viewed from the line of sight E2. For specific methods of adjusting the spatial posture of the display interface of the display device, reference can be made to the relevant technology, which will not be described one by one here.
[0097] In this way, by simultaneously adjusting the positions and / or angles of the display interfaces of the two display devices in space, the user's need to obtain driving information can be quickly met, thereby improving the user's driving experience.
[0098] In some embodiments, Figure 1 As shown, the control method 100 may further include:
[0099] Step 104: When the line of sight is located within a predetermined area and the display content of the first display device and the display content of the second display device are continuous, adjust the position and / or angle of the display interface of the first display device and / or the second display device in space following the line of sight, so that the display interface of the first display device and the display interface of the second display device are continuous when observed from the line of sight.
[0100] In the embodiment of the present invention, the information to be prompted can be displayed in the display interface in the form of text or in the form of pictures. Sometimes, when the text information has a lot of content or the picture information is large in size, the text or picture may be small or blurred through one display interface, which is not conducive to the user obtaining the information. The embodiment of the present invention can facilitate the user to obtain the information by displaying continuous information on two display interfaces.
[0101] For example, Figure 3 As shown in (a), when the content in the display interface 201 is continuous with the content in the display interface 202, the information displayed in the area A2 and the information displayed in the area A1 need to be continuously read or acquired by the user, so that the user's line of sight may move along with the read information, and the two display interfaces may separate or overlap as the line of sight moves. Therefore, the user's line of sight direction can be periodically detected, and the two display interfaces can be adjusted at any time following the line of sight direction, so that no matter from which line of sight the two display interfaces are observed, they are continuous, and thus, the information displayed at the junction of the two display interfaces is also coherent.
[0102] In this way, by adjusting the position and / or angle of the two display interfaces in space according to the line of sight, the two display interfaces are always continuous when observed from the line of sight, which further facilitates users to obtain driving information and reduces visual fatigue.
[0103] In the embodiment of the present invention, step 103 may be replaced by step 104, or step 104 and step 103 may be implemented in combination, which is not limited in the embodiment of the present invention.
[0104] In some embodiments, Figure 1 As shown, the control method 100 may further include:
[0105] Step 105: When the duration that the line of sight is within the predetermined area exceeds a first threshold, adjust the position and / or angle of the display interface of the first display device and / or the second display device in space so that the display interface of the first display device and the display interface of the second display device are continuous when observed from the line of sight.
[0106] In actual application scenarios, users sometimes need to temporarily turn their sight to the side to observe the road conditions, and then turn their sight back to the front to observe the road conditions. They may need to turn back and forth multiple times. If the display interface is adjusted every time the sight is turned, it will increase energy consumption and may also distract the user's attention. Therefore, the duration of the user's fixed sight direction can be detected, and after detecting that the sight direction is fixed, the position and / or angle of the display interface in space can be adjusted.
[0107] In this way, by detecting the duration that the line of sight is within the predetermined area, the position and / or angle of the display interface in space is adjusted after detecting that the duration exceeds a threshold, which helps to reduce energy consumption, help users concentrate, and improve driving safety.
[0108] In the embodiment of the present invention, step 105 may replace step 103, or step 105 may be implemented in combination with step 103. In addition, steps 103 to 105 may replace or be combined with each other, which is not limited in the embodiment of the present invention.
[0109] It can be seen from the above embodiments that by adjusting the display interfaces of the two display devices according to the user's line of sight, the two display interfaces are continuous when observed from the user's line of sight. Therefore, it is convenient for the user to obtain driving information and reduce visual fatigue.
[0110] Furthermore, by first adjusting the display interface of one display device to a posture suitable for user viewing, and then adjusting the display interface of another display device to a position continuous with the display interface of the one display device, the adjustment of the display interface posture can be easily achieved.
[0111] Furthermore, by simultaneously adjusting the positions and / or angles of the display interfaces of the two display devices in space, the needs of users can be quickly met, thereby improving the driving experience of users.
[0112] Furthermore, by adjusting the position and / or angle of the two display interfaces in space according to the line of sight, the two display interfaces are always continuous when observed from the line of sight, which further facilitates users to obtain driving information and reduces visual fatigue.
[0113] Furthermore, by detecting the duration that the line of sight is within the predetermined area, the position and / or angle of the display interface in space is adjusted after detecting that the duration exceeds a threshold, which helps to reduce energy consumption, help users concentrate, and improve driving safety.
[0114] Furthermore, by limiting the predetermined area, the position and / or angle of the display interface of the first display device and / or the second display device in space can be adjusted more accurately based on the user's line of sight, which is beneficial to improving the user's driving experience.
