[0002] As the level of automobile intelligence continues to improve, vehicles are usually equipped with screens. However, the car screen will cause side window imaging problems under certain lighting conditions, that is, the car screen will be reflected on the window (side window) next to the driver to form a virtual image, which may interfere with the driver's field of vision and affect driving safety.

[0003] Therefore, when there is a virtual image of the screen in the car window, how to reduce the interference of the virtual image on the driver's field of vision and improve driving safety has become an urgent problem to be solved. Summary of the invention

[0004] The present application provides a method for controlling a vehicle screen, a device for controlling a vehicle screen, and a vehicle. The method can reduce the interference of a virtual image of the screen on the driver's field of vision when there is a virtual image of the screen in the vehicle window, thereby improving driving safety.

[0005] In a first aspect, a method for controlling a vehicle screen is provided, the method comprising:

[0006] When a target virtual image exists on a target window of a vehicle, a risk level of interference of the target virtual image on a driver's target field of view is determined; based on the target virtual image, a target screen in the vehicle is determined; based on the risk level, target configuration parameters of the target screen are determined; based on the target configuration parameters, display of the target screen is controlled.

[0007] In an embodiment of the present application, by detecting the target virtual image on the target window of the vehicle, the risk level of interference of the virtual image on the driver's field of view can be evaluated, and the configuration parameters of the target screen can be determined according to the risk level, and the target screen can be controlled for display based on the target configuration parameters; in the above scheme, since the target configuration parameters are determined based on the risk level, different target configuration parameters can be determined for situations with different risk levels, and the configuration parameters can be flexibly formulated, so that when the risk level is low, the configuration parameters of the screen can be kept small to avoid interference to users who are watching the screen; the configuration parameters of the screen can be adjusted when the risk level is high to reduce the impact of the screen on the driver's field of view, thereby improving driving safety; since the target screen is controlled for display based on the target configuration parameters, the adverse effects of the virtual image on the driver's field of view can be weakened, making the driver's field of view clearer, thereby improving driving experience and safety.

[0008] In conjunction with the first aspect, in some possible implementations, determining target configuration parameters of a target screen based on the risk level includes:

[0010] In an embodiment of the present application, when the risk level is less than a preset risk level, the current display configuration of the target screen is maintained, so that the adjustment of the display configuration of the screen can avoid causing visual interference to occupants in the vehicle when the virtual image does not affect the driver's field of view; when the risk level is greater than or equal to the preset risk level, the virtual image has interfered with the driver's field of view. Adjusting the screen-off ratio or brightness parameters of the target screen can reduce the interference of the virtual image corresponding to the target screen on the driver's field of view.

[0013] In an embodiment of the present application, the determination of the target configuration parameters is related to the type of content currently displayed on the screen, and the target configuration parameters can be adjusted according to scene requirements to improve the user experience; or the user is allowed to make selections within a preset configuration parameter range, providing a flexible parameter selection method that can meet user needs for personalized settings and improve the user experience.

[0014] In combination with the first aspect and the above implementation manner, in some possible implementation manners, when the target configuration parameter is determined based on the user's selection operation of the configuration parameter in the preset configuration parameter range, the method further includes:

[0015] Output predicted risk information corresponding to the configuration parameters of the selected operation; the predicted risk information is used to indicate the risk of interference of the driver's target field of view by the virtual image predicted to be generated on the target window when the target screen is displayed with the configuration parameters of the selected operation; based on the target configuration parameters, control the display of the target screen, including: responding to a user operation on the predicted risk prompt information, and controlling the display of the target screen based on the configuration parameters of the selected operation.

[0016] In an embodiment of the present application, when a configuration parameter is selected within the preset configuration parameter range, the predicted risk information corresponding to the configuration parameter is output, which can remind the user of the risk situation when the currently selected configuration parameter is displayed, which is conducive to the user to adjust the selection of configuration parameters, and control the screen display based on the configuration parameters confirmed by the user, thereby improving driving safety.

[0017] In combination with the first aspect and the above implementations, in some possible implementations, the present invention further includes:

[0019] In an embodiment of the present application, the screen whose display content is consistent with the virtual image content in each screen is determined as the target screen, so that the target screen corresponding to the target virtual image can be accurately determined; the target screen is determined based on the position of the target virtual image and the position of each screen in the vehicle, so that the target screen corresponding to the target virtual image can be accurately determined; since the target screen is accurately determined, it is possible to avoid mistakenly adjusting other screens and affecting the experience of people in the car.

[0020] In combination with the first aspect and the above implementations, in some possible implementations, controlling the target screen display based on the target configuration parameters includes:

[0021] When a target virtual image is detected on a target window, the target screen display is controlled based on the target configuration parameters; or, when a target virtual image is detected on a target window, a prompt message is output; in response to a user's confirmation operation on the prompt message, the target screen display is controlled based on the target configuration parameters; wherein the prompt message is used to prompt the user whether to adjust the configuration parameters of the target screen; the confirmation operation is the user's confirmation to display with the target configuration parameters; or, when it is detected that the driver's head moves in the direction of the target window, the target screen display is controlled based on the target configuration parameters.

[0022] In an embodiment of the present application, when a virtual image is detected on a target window, the target screen is controlled to display with the target configuration parameters, and can automatically adjust when a virtual image is detected on the target window to ensure that the driver's field of view remains clear, reduce the potential impact of the virtual image on driving safety, and improve driving safety; or, when a virtual image is detected on the target window, a prompt message is output and based on the user's confirmation operation on the prompt message, the configuration parameters confirmed by the user are displayed, and the user can be provided with flexible configuration parameter selections to meet user needs, while improving the user experience and reducing the interference of the virtual image on the driver's field of view, thereby improving driving safety; or, when it is detected that the driver's head is moving in the direction of the target window, the target screen is controlled to display the target configuration parameters, which can ensure the timeliness of the adjustment of the screen's configuration parameters and improve driving safety.

[0025] In an embodiment of the present application, by obtaining the position of the driver's head and the position of the target object, the driver's target field of view can be accurately predicted; since the driver's target field of view can be accurately predicted, the risk of virtual image interference with the driver's field of view can be more accurately evaluated, providing a reliable basis for adjusting the screen configuration parameters.

[0028] In the embodiment of the present application, by calculating the overlapping area between the target virtual image and the driver's target field of view, the degree of interference of the virtual image on the driver's field of view can be quantified. According to the size of the overlapping area, the system divides the risk level into three levels, corresponding to different adjustment strategies; since different adjustment strategies are set for different interference levels, the adjustment of the screen configuration parameters can be controlled more accurately, ensuring that appropriate measures are taken at different risk levels to reduce interference with the driver's field of view.

[0045] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0046] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0047] With the rapid development of vehicle intelligent technology, in-vehicle screens have gradually become an important part of the vehicle cockpit, which can be used to display entertainment information and navigation information. However, in the prior art, when the vehicle is driving, virtual images may be generated on the window due to the screen display content. These virtual images may interfere with the driver's field of vision, especially when the driver is observing the road conditions. The overlap of the virtual image and the driver's field of vision may cause visual confusion and affect driving safety. Figure 1 As shown, Figure 1 A scene diagram of a vehicle provided in an embodiment of the present application; the vehicle 100 includes a central control screen 100, a right rearview mirror 120 and a virtual image 130; the central control screen 100 forms a virtual image 130 on the right side window of the co-pilot, blocking the driver's field of view of the right rearview mirror 120, which makes it impossible for the driver to observe the condition of the vehicle on the right side, which may lead to wrong judgment and affect driving safety.

[0048] In view of this, this solution provides a method for controlling a vehicle screen, which detects the target virtual image on the target window, evaluates its risk level of interference with the driver's target field of view, and adjusts the configuration parameters of the target screen according to the risk level. First, determine the risk level of interference of the target virtual image with the driver's field of view, and then determine the target configuration parameters of the target screen (such as screen off ratio or brightness parameters) based on the risk level, and control the target screen display based on the target configuration parameters; adjust the target screen display to ensure that the driver's field of view remains clear, reduce the impact of the virtual image on driving safety, and improve driving experience and safety.

[0049] Combine the following Figure 2 A method for controlling a vehicle screen provided in an embodiment of the present application is described in detail.

[0050] Figure 2 is a schematic flow chart of a method for controlling a vehicle screen provided in an embodiment of the present application. Figure 2 As shown, the method 200 includes S210 to S240, and S210 to S240 are described in detail below.

[0051] For example, Figure 2 The control method 200 of the vehicle screen shown can be executed by the vehicle; or, executed by a processor in the vehicle; or, executed by a chip installed in the processor of the vehicle.

[0052] S210: When a target virtual image exists on a target window of the vehicle, determine a risk level of interference of the target virtual image on the driver's target field of vision.

[0053] The target objects may include rearview mirrors and front windshields.

[0054] For example, when the target object is the left rearview mirror, the driver's target field of view is used to represent the observation area when the driver looks at the left rearview mirror through the left window. When the target object is the central control screen, the driver's target field of view is the observation area when the driver looks at the central control screen. In one implementation, the above method includes:

[0055] Based on the target virtual image and the driver's target field of view, the overlapping area is determined; when the overlapping area is equal to zero, the risk level is determined to be the first risk level; when the overlapping area is greater than zero and less than a preset area threshold, the risk level is determined to be the second risk level; when the overlapping area is greater than or equal to the preset area threshold, the risk level is determined to be the third risk level.

[0056] In an embodiment of the present application, the overlapping area between the target virtual image and the driver's target field of view is determined, and the risk level is determined based on the size of the overlapping area.

[0057] Exemplarily, the target field of view when the driver looks at the left rearview mirror can be predicted based on the curved surface parameters of the window glass on the left side of the driver, the parameters of the human eye point and the position of the left rearview mirror. The target field of view can be area A on the window glass on the left side of the driver; area B on the window glass on the left side of the driver where the target virtual image is located can be determined based on the target virtual image, the position of the driver's eye point and the curved surface parameters of the window glass on the left side of the driver; determine whether there is an overlapping area between area A and area B. If there is no overlapping area, it is determined to be a first risk level (low risk). At this time, the target virtual image is imaged on the window glass on the left side of the driver, but does not affect the driver's gaze at the left rearview mirror; if there is an overlapping area, and the overlapping area is less than a preset area threshold, it is determined to be a second risk level (medium risk). At this time, the target virtual image blocks the driver's field of view when looking at the left rearview mirror, but the imaging area is small; if there is an overlapping area, and the overlapping area is greater than or equal to the preset area threshold, it is determined to be a third risk level (high risk). At this time, the target virtual image blocks the driver's field of view when looking at the left rearview mirror, and the imaging area is large. The surface parameters may include the shape, size, thickness, refractive index, transmittance, curvature and other parameters of the glass.

[0058] It should be understood that the intersection between the imaging area of ​​the target virtual image on the target window and the area of ​​the driver's target field of view on the target window is the overlapping area, the overlapping area is the area of ​​the overlapping area, and the overlapping area is less than or equal to the two-dimensional area of ​​the area of ​​the driver's target field of view on the target window.

[0059] In the above scheme, by calculating the overlapping area between the target virtual image and the driver's target field of view, the degree of interference of the virtual image on the driver's field of view can be quantified. According to the size of the overlapping area, the system divides the risk level into three levels, corresponding to different adjustment strategies; since different adjustment strategies are set for different interference levels, the adjustment of screen configuration parameters can be controlled more accurately, ensuring that appropriate measures are taken at different risk levels to reduce interference with the driver's field of view.

[0060] In one implementation, the method further includes:

[0061] The head position of the driver and the position of the target object in the cockpit are obtained; based on the position of the target object and the head position, the driver's target field of view is determined.

[0062] In an embodiment of the present application, the driver's target field of view may be determined based on the driver's head position and the position of the target object.

[0063] Optionally, the driver's target visual field area may be determined based on the driver's eye point position and the position of the target object.

[0064] Exemplarily, the eye position of the driver and the position of the target object are determined, and based on the eye position, the position of the target object and the curved surface parameters of the glass, the target field of view when the driver is looking at the target object can be determined.

[0065] It should be noted that the driver's target field of view is the field of view of the current driver when he or she is looking at the target object. Different eye positions need to be determined for drivers of different heights, and the field of view is determined based on the current driver's eye position.

[0066] In the above scheme, by obtaining the position of the driver's head and the position of the target object, the driver's target field of view can be accurately predicted; since the driver's target field of view can be accurately predicted, the risk of virtual image interference with the driver's field of view can be more accurately evaluated, providing a reliable basis for adjusting the screen configuration parameters.

[0067] S220: Determine a target screen in the vehicle based on the target virtual image.

[0068] In one implementation, the method further includes:

[0069] Obtaining the virtual image content of the target virtual image, the position of the target virtual image, the display content of each screen in the vehicle and the position of each screen; determining the target screen in the vehicle based on the target virtual image, including: determining the screen whose display content in each screen is consistent with the virtual image content as the target screen; or determining the target screen based on the position of the target virtual image and the positions of each screen in the vehicle.

[0070] In an embodiment of the present application, the screen in the vehicle with the same content as the target virtual image can be determined as the target screen according to the content of the target virtual image; or the target screen can be determined based on the imaging position of the target virtual image and the positions of each screen in the vehicle.

[0071] Exemplarily, the virtual image content can be obtained through a camera configured in the vehicle, and the display content of each screen can be obtained through the vehicle media system or camera, and compared with the virtual image content, and the screen whose display content is consistent with the virtual image content is determined as the target screen.

[0072] Exemplarily, the target screen causing the virtual image may be determined based on the positions of the various screens in the cockpit, the light intensity and the light angle in the current environment, and the position of the virtual image.

[0073] In one embodiment, if the display contents of multiple screens of the vehicle are consistent with the virtual image contents, the target screen causing the virtual image can be determined based on the positions of the screens in the cockpit, the light intensity and light angle in the current environment, and the position of the virtual image.

[0074] In the above scheme, the screen whose display content is consistent with the virtual image content in each screen is determined as the target screen, so that the target screen corresponding to the target virtual image can be accurately determined; the target screen is determined based on the position of the target virtual image and the position of each screen in the vehicle, so that the target screen corresponding to the target virtual image can be accurately determined; since the target screen is accurately determined, it is possible to avoid mistakenly adjusting other screens and affecting the experience of people in the car.

[0075] S230: Determine target configuration parameters of the target screen based on the risk level.

[0076] In one implementation, it includes:

[0077] If the risk level is less than the preset risk level, the current configuration parameters of the target screen are determined as the target configuration parameters; if the risk level is greater than or equal to the preset risk level, the target configuration parameters are determined based on the risk level.

[0078] Among them, the target configuration parameters include the screen-off ratio or the brightness parameter, and the screen-off ratio is used to indicate the ratio of the area of ​​the screen-off region in the target screen to the area of ​​the target screen; since the virtual image formed on the window is larger when the screen display area is larger, the screen-off ratio is positively correlated with the risk level, and the higher the risk level, the greater the screen-off ratio of the screen, and thus the imaging area of ​​the target virtual image on the window becomes smaller; since the brightness parameter is high, the intensity of the light reflected on the window will be greater, making the virtual image more interfering with the driver's field of vision, and therefore the brightness parameter is negatively correlated with the risk level, and the higher the risk level, the lower the brightness parameter of the screen, and thus the interference of the target virtual image on the window with the driver's field of vision can be reduced.

[0079] It should be understood that in the embodiments of the present application, three risk levels are set: risk level 1 corresponds to the first risk level, risk level 2 corresponds to the second risk level, and risk level 3 corresponds to the third risk level; the above is only an example of the risk level, and the specific risk level can be set differently by professional and technical personnel according to specific circumstances. This is only an exemplary description, and the present application does not impose any limitation on this.

[0080] It should be noted that the value of the risk level is positively correlated with the degree of occlusion of the target's field of view by the virtual image.

[0081] Exemplarily, the preset risk level can be set to 2. If the current risk level is detected to be 1 (i.e., at the first risk level), the current configuration parameters of the target screen are determined as the target configuration parameters, that is, the configuration parameters of the target screen are not adjusted; if the current risk level is detected to be greater than or equal to 2 (i.e., at the second risk level or the third risk level), the target configuration parameters are determined based on the current risk level.

[0082] In the above scheme, when the risk level is less than the preset risk level, the current display configuration of the target screen is maintained, so that the visual interference to the occupants of the vehicle caused by adjusting the display configuration of the screen can be avoided when the virtual image does not affect the driver's field of view; when the risk level is greater than or equal to the preset risk level, the virtual image has interfered with the driver's field of view. Adjusting the screen-off ratio or brightness parameters of the target screen can reduce the interference of the virtual image corresponding to the target screen on the driver's field of view.

[0083] In one implementation, it includes:

[0084] The configuration parameters corresponding to the risk level are determined as target configuration parameters; or, based on the risk level, a preset configuration parameter range is determined; and the configuration parameters selected by the user for operation within the preset configuration parameter range are determined as target configuration parameters.

[0085] The configuration parameter corresponding to the risk level is related to the content type of the current displayed content on the target screen.

[0086] Exemplarily, a mapping relationship between risk levels and configuration parameters may be preset, and the target configuration parameters may be determined according to the current risk level and the mapping relationship between the risk level and the configuration parameters.

[0087] Table 1

[0088] Risk Level 1 2 3 Screen off ratio 0％ 20％ 30％ Brightness parameters 100 70 40

[0089] Exemplarily, when the configuration parameter is the screen-off ratio, when the risk level is 1, the virtual image of the target screen on the car window does not interfere with the driver's field of view, and can be displayed with the original configuration parameters, that is, the screen-off ratio is 0; when the risk level is 2, the virtual image interferes with the driver's field of view, but the occlusion area is not large, and the target screen needs to be turned off by turning off 20% of the entire screen display area; when the risk level is 3, the virtual image interferes with the driver's field of view, and the occlusion area is large, and the target screen needs to be turned off by turning off 30% of the entire screen display area.

[0090] It should be noted that the configuration parameters corresponding to the risk level are related to the content type of the current displayed content on the target screen.

[0091] Exemplarily, when the configuration parameter is the screen-off ratio, if the current display content of the target screen is auditory content (for example, car radio or music, etc.), the target configuration parameter corresponding to the risk level 2 can be 30%, and the target configuration parameter corresponding to the risk level 3 can be 40%; if the current display content of the target screen is ordinary visual content (for example, movies), the target configuration parameter corresponding to the risk level 2 can be 20%, and the target configuration parameter corresponding to the risk level 3 can be 30%; if the current display content of the target screen is high-definition visual content (for example, high-definition map) or content that affects driving safety (for example, alarm information or navigation information, etc.), the target configuration parameter corresponding to the risk level 2 can be 10%, and the target configuration parameter corresponding to the risk level 3 can be 20%.

[0092] In an embodiment of the present application, the screen-off ratio may be achieved by turning off some of the light emitting diodes (LEDs) of the screen.

[0093] For example, Figure 3 As shown in (a), the screen interface 301 is the display interface of the target screen before adjustment, and all LEDs in the backlight area of ​​the target screen are lit; if the screen off ratio is determined to be 20% based on the risk level; the default display screen middle area is 80%, such as Figure 6 As shown in (a) in .

[0094] In one embodiment, if a virtual image is detected on the vehicle window, a function activation interface is displayed, such as Figure 3 As shown in (b) in FIG. 3 ; if it is detected that the user selects the cancel control 303, the function activation interface is exited, the current configuration parameters of the target screen are maintained, and no adjustment is made; if it is detected that the user selects the confirm control 302, the risk level is determined, and the target configuration parameters are obtained based on the risk level, and the selection interface is displayed, such as Figure 3 As shown in (c); if it is detected that the user selects the custom control 304, the custom interface is displayed, such as Figure 3 As shown in (d) in the figure; if the user selects the confirmation control 305, the target screen is displayed with the target configuration parameters; if it is detected that the user selects the cancel control 306, the interface is exited, the current configuration parameters of the target screen are maintained, and no adjustment is made.

[0095] For example, if it is detected that the user selects the right control 309, the screen off ratio is 50%, such as Figure 3 As shown in (e) in the figure, the target screen is controlled to display with this parameter, and the display effect is as follows Figure 3 As shown in (f) in FIG. 3 , area 301 is an area in the backlight area of ​​the target screen where the LED is in a lit state; area 311 is an area in the backlight area of ​​the target screen where the LED is in an off state.

[0096] Optional, Figure 3 The function activation interface shown in (b) can also be Figure 5 (a) in the replacement; if a virtual image is detected on the car window, the output is as follows Figure 5 The function activation interface shown in (a) in the figure, Figure 5 In the function activation interface shown in (a), the target configuration parameters are previewed to display the effect presented in the recommended manner, wherein area 501 can be an area in which the LED in the backlight area of ​​the target screen is in a lit state; area 502 can be an area in which the LED in the backlight area of ​​the target screen is in an unlit state.

[0097] Optionally, if it is detected that the user selects the confirmation control 302, the risk level is determined, and the target configuration parameters are obtained based on the risk level, the target screen is controlled to be displayed with the target configuration parameters, and the selection interface is output, such as Figure 5 As shown in (a); the display area 501 can be a preview state of the area in the backlight area of ​​the target screen where the LED is in the lit state (can be presented in blue); the off-screen area 502 is a preview state of the area in the backlight area of ​​the target screen where the LED is in the off state (can be presented in purple).

[0098] It should be noted that the above-mentioned control selection operation can be a click operation of the user on the screen, or it can be a selection operation of the control through voice; this application does not impose any limitation on this.

[0099] The above configuration parameter is taken as an example of the screen off ratio. The configuration parameter can also be a brightness parameter, which is not limited in this application. Optionally, when the screen off ratio is 20%, only 80% of the original screen display area is displayed, and the 80% area only displays the display content at the corresponding position, that is, when the screen off ratio is 20%, the display content of the extinguished part is not displayed; or, the display content is scaled, and the 80% area displays all the display content.

[0100] In one embodiment, the configuration parameters for the operation selected by the user within a preset configuration parameter range are used to determine the target configuration parameters.

[0101] For example, Figure 3 As shown in (c) of FIG. 3 , if it is detected that the user selects the custom control 304, the custom interface is displayed, such as Figure 3 As shown in (d) in the figure, the custom interface includes a screen-off ratio progress bar 310, a middle control 307, a left control 308, and a right control 309. A preset configuration parameter range may be provided to the user for selection within the preset configuration parameter range, and the configuration parameter selected by the user is determined as the target configuration parameter.

[0102] In one embodiment, if it is detected that the user selects the display position, it is detected that the user selects the middle control 307, the screen off ratio is 20%, and the target screen is controlled to display with this parameter, and the display effect is as follows: Figure 6 As shown in (a); if it is detected that the user selects the left control 308, the screen off ratio is 50%, and the target screen is controlled to display with this parameter, and the display effect is as follows Figure 6 As shown in (b); if it is detected that the user selects the right control 309, the screen off ratio is 50%, and the target screen is controlled to display with this parameter, and the display effect is as follows Figure 6 As shown in (c) in the figure, the area 601 may be an area in the backlight area of ​​the target screen where the LED is in a lit state; and the area 602 may be an area in the backlight area of ​​the target screen where the LED is in an unlit state.

[0103] In one embodiment, if it is detected that the user selects the display position, it is detected that the user selects the middle control 307, the brightness parameter is 50, and the target screen is controlled to display with this parameter, and the display effect is as follows: Figure 6 As shown in (a); if it is detected that the user selects the left control 308, the brightness parameter is 50, and the target screen is controlled to display with this parameter, the display effect is as follows Figure 6 As shown in (b); if it is detected that the user selects the right control 309, the brightness parameter is 50, and the target screen is controlled to display with this parameter, the display effect is as follows Figure 6 As shown in (c) of FIG. 8 , area 601 may be an area where the brightness parameter of the target screen is 100; and area 602 may be an area where the brightness parameter of the target screen is 50.

[0104] It should be noted that the brightness parameter can also be understood as a percentage value of the original LED luminous intensity; for example, assuming that the LED luminous intensity of the original target screen is 100%, the target configuration parameter is determined to be 50 based on the risk level (the brightness parameter is 50), and when the target screen is controlled based on the target configuration parameter, the LED luminous intensity of the target screen is controlled to be 50%.

[0105] In one embodiment, if a virtual image is detected on the vehicle window, a function activation interface is displayed, such as Figure 3 As shown in (b) in FIG. 3 ; if it is detected that the user selects the cancel control 303, the function activation interface is exited, the current configuration parameters of the target screen are maintained, and no adjustment is made; if it is detected that the user selects the confirm control 302, the risk level is determined, and the target configuration parameters are obtained based on the risk level, and the selection interface is displayed, such as Figure 3 As shown in (c); if it is detected that the user selects the custom control 304, the custom interface is displayed, such as Figure 4As shown in (a); if the user selects the confirmation control 305, the target screen is displayed with the target configuration parameters; if it is detected that the user selects the cancel control 306, the interface is exited, the current configuration parameters of the target screen are maintained, and no adjustment is made.

[0106] For example, if it is detected that the user selects the right control 309, the screen off ratio is 50%, the brightness parameter is 50, and the target screen is controlled to display with the parameters, the display effect is as follows: Figure 4 As shown in (c) in the figure, region 402 is a region where the LED in the backlight region of the target screen is off; region 403 is a region where the luminous intensity of the LED in the backlight region of the target screen is 50% of the maximum luminous intensity.

[0107] It should be noted that when providing the user with a preset configuration parameter range, the preset configuration parameter range can be determined based on the current risk level and the type of content currently displayed on the target screen. When the configuration parameter is the screen off ratio, the upper limit of the preset configuration parameter range is proportional to the risk level; when the configuration parameter is the brightness parameter, the upper limit of the preset configuration parameter range is inversely proportional to the risk level.

[0108] In the above scheme, the determination of the target configuration parameters is related to the current display content type of the screen. The target configuration parameters can be adjusted according to the scene requirements to improve the user experience; or the user is allowed to choose within the preset configuration parameter range, providing a flexible parameter selection method, which can meet user needs for personalized settings and improve the user experience.

[0109] In one implementation, the method further includes:

[0110] Output predicted risk information corresponding to the configuration parameters of the selection operation; the predicted risk information is used to indicate the risk of interference of the driver's target field of view by the virtual image predicted to be generated on the target window when the target screen is displayed with the configuration parameters of the selection operation; based on the target configuration parameters, control the display of the target screen, including: responding to the user operation on the predicted risk prompt information, and before the driver looks at the target object, controlling the display of the target screen based on the configuration parameters of the selection operation.

[0111] In one embodiment, Figure 3 The custom interface shown in (d) can also be Figure 5 Replace (b) in .

[0112] For example, if it is detected that the user selects to determine the target configuration parameter within the preset configuration parameter range, that is, it is detected that the user selects the custom control 304, the predicted risk information can be output, such as Figure 5As shown in (b) in the figure; the user sets the screen configuration parameters in the custom area, such as adjusting the screen off ratio or brightness parameters; intelligent prediction is performed based on the configuration parameters adjusted by the user in the custom area, the risk situation of the target screen after displaying with the configuration parameters is simulated, and an intelligent prediction result 503 (i.e., predicted risk information) is generated, and a suggestion 504 is generated based on the intelligent prediction result 503.

[0113] In one embodiment, after it is detected that the user has adjusted the configuration parameters in the custom interface, if no operation is detected within a preset time (eg, 3 seconds), the target screen display is controlled using the configuration parameters adjusted by the user.

[0114] In another embodiment, after it is detected that the user adjusts the configuration parameters in the custom interface, no operation is detected within a first preset time period, and a confirmation interface is displayed to confirm whether to control the target screen display with the adjusted configuration parameters. If it is detected that the user confirms to control the target screen display with the adjusted configuration parameters, the target screen display is controlled with the configuration parameters adjusted by the user; if it is detected that the user cancels controlling the target screen display with the adjusted configuration parameters, the target screen is not controlled; if it is detected that the user has no operation within the preset time period, the target screen display is controlled with the configuration parameters adjusted by the user.

[0115] In the above scheme, when a configuration parameter is selected within the preset configuration parameter range, the predicted risk information corresponding to the configuration parameter is output, which can remind the user of the risk situation when the currently selected configuration parameter is displayed, which is conducive to the user to adjust the selection of configuration parameters, so that before the driver looks at the target object, the screen display is controlled based on the configuration parameters confirmed by the user, thereby improving driving safety.

[0116] S140. Control the target screen display based on the target configuration parameters.

[0117] In one implementation, it includes:

[0118] When a target virtual image is detected on a target window, the target screen display is controlled based on the target configuration parameters; or, when a target virtual image is detected on a target window, a prompt message is output; in response to a user's confirmation operation on the prompt message, the target screen display is controlled based on the target configuration parameters; the confirmation operation is the user's confirmation to display with the target configuration parameters; or, when it is detected that the driver's head moves in the direction of the target window, the target screen display is controlled based on the target configuration parameters.

[0119] The prompt information is used to prompt the user whether to adjust the configuration parameters of the target screen; the target window can be the front windshield, the driver's left window and the co-pilot's right window.

[0120] As a preferred embodiment provided in the embodiments of the present application, the target screen can be controlled to display based on the target configuration parameters before the driver looks at the target object, thereby avoiding the virtual image from blocking the field of view and ensuring that the driver's field of view always remains clear, thereby reducing the potential impact of the virtual image on driving safety and improving driving safety.

[0121] In the embodiments provided in the present application, when it is detected that the driver is looking at the target object, or after it is detected that the driver is looking at the target object, the target screen can be controlled to display based on the target configuration parameters, which can weaken the adverse effects of the virtual image on the driver's field of view, making the driver's field of view clearer, thereby improving driving safety.

[0122] In one embodiment, when it is detected that a virtual image caused by a screen in the vehicle exists on a target vehicle window, the target screen is controlled to be displayed with target configuration parameters.

[0123] Exemplarily, a virtual image is detected on the target vehicle window, the risk level caused by the virtual image is determined to be 2, and the current display content of the target screen is of ordinary visual type, the target configuration parameter (screen off ratio) is determined to be 20%, and the target screen is controlled to display with a screen off ratio of 20%.

[0124] In one embodiment, when a virtual image caused by a screen in a vehicle is detected on a target window, a prompt message is output, which is used to prompt the user that the screen in the vehicle generates side window imaging, causing driving risks, and prompt the user to adjust the configuration parameters of the screen; if it is detected that the user has no operation within a preset time, the target screen is not adjusted; if it is detected that the user selects the confirmation control 302, the risk level is determined, and the target configuration parameters are obtained based on the risk level, the target screen is controlled to display with the target configuration parameters, and the selection information is output, such as Figure 5 As shown in (a) in .

[0125] In one embodiment, if it is detected that the driver's head moves toward the direction of the target window, the target screen is controlled to display with the target configuration parameters.

[0126] Exemplarily, the target window is the driver's left window, the target object is the left rearview mirror, the central control screen forms a virtual image on the left window, and blocks the driver's field of view of the left rearview mirror; the risk level is determined based on the blocked area, and the target configuration parameters are determined based on the risk level; if it is detected that the driver's head turns to the left exceeding a preset angle threshold (for example, 10°), the screen-off ratio of the central control screen is adjusted to 20%.

[0127] In one embodiment, when it is detected that the vehicle is in a driving state, if it is detected that a virtual image caused by a screen inside the vehicle exists on a target window, the target screen is controlled to display with target configuration parameters.

[0128] Exemplarily, the driving status may be one or more of the following: the vehicle's gear is not in the parking gear, the vehicle's current speed exceeds a preset speed threshold, the vehicle's current acceleration exceeds a preset acceleration threshold, and the vehicle's handbrake is in a non-braking state (or the electronic handbrake system is in an inactive state).

[0129] In one embodiment, when it is detected that the vehicle is in a powered-on state, if it is detected that there is a virtual image on the target window caused by the screen in the vehicle, the target screen is controlled to display with the target configuration parameters. In the above scheme, when it is detected that there is a virtual image on the target window, the target screen is controlled to display with the target configuration parameters, which can automatically adjust when the virtual image is detected on the target window to ensure that the driver's field of vision remains clear, reduce the potential impact of the virtual image on driving safety, and improve driving safety; or, when it is detected that there is a virtual image on the target window, a prompt message is output and based on the user's confirmation operation of the prompt message, the configuration parameters confirmed by the user are displayed, which can provide users with flexible configuration parameter selection, meet user needs, and reduce the interference of the virtual image on the driver's field of vision while improving the user experience, thereby improving driving safety; or, when it is detected that the driver's head moves in the direction of the target window, the target screen is controlled to display the target configuration parameters, which can ensure the timeliness of the adjustment of the screen's configuration parameters and improve driving safety.

[0130] In the above embodiment, by detecting the target virtual image on the target window of the vehicle, the risk level of interference of the virtual image on the driver's field of view can be evaluated, and the configuration parameters of the target screen can be determined according to the risk level, and the target screen can be controlled for display based on the target configuration parameters; in the above scheme, since the target configuration parameters are determined based on the risk level, different target configuration parameters can be determined for situations with different risk levels, and the configuration parameters can be flexibly formulated, so that when the risk level is low, the configuration parameters of the screen can be kept small to avoid interference to users who are watching the screen; when the risk level is high, the configuration parameters of the screen can be adjusted to reduce the impact of the screen on the driver's field of view, thereby improving driving safety; since the target screen is controlled for display based on the target configuration parameters, the adverse impact of the virtual image on the driver's field of view can be weakened, making the driver's field of view clearer, thereby improving driving experience and safety.

[0131] Combine the following Figure 7 Another method for controlling a vehicle screen provided in an embodiment of the present application is illustrated by way of example.

[0132] Figure 7 FIG. 1 is a schematic flow chart of another method for controlling a vehicle screen provided in an embodiment of the present application. Figure 7As shown, the method 700 includes S710 to S760, and S710 to S760 are described in detail below.

[0133] For example, Figure 7 The vehicle screen control method 700 shown may be executed by the vehicle; or, executed by a processor in the vehicle; or, executed by a chip mounted in the processor of the vehicle.

[0134] S710: When there is a virtual image on the left side window of the driver, obtain the driver's head position and the left rearview mirror position, and determine the risk level of the virtual image interfering with the driver's target field of view.

[0135] Exemplarily, the target field of view when the driver looks at the left rearview mirror can be predicted based on the curved surface parameters of the driver's left window glass, the parameters of the human eye point and the position of the left rearview mirror. The target field of view can be area A on the driver's left window glass; area B on the driver's left window glass where the target virtual image is located can be determined based on the target virtual image, the driver's eye point position and the curved surface parameters of the driver's left window glass; determine whether there is an overlapping area between area A and area B. If there is no overlapping area, it is determined to be a first risk level (low risk). At this time, the target virtual image is imaged on the driver's left window glass, but does not affect the driver's gaze at the left rearview mirror; if there is an overlapping area, and the overlapping area is less than a preset area threshold, it is determined to be a second risk level (medium risk). At this time, the target virtual image blocks the driver's field of view when looking at the left rearview mirror, but the imaging area is small; if there is an overlapping area, and the overlapping area is greater than or equal to the preset area threshold, it is determined to be a third risk level (high risk). At this time, the target virtual image blocks the driver's field of view when looking at the left rearview mirror, and the imaging area is large.

[0136] Optionally, the driver's target field of view may be determined based on the driver's eye position and the position of the left rearview mirror.

[0137] Optionally, the implementation of S710 can refer to Figure 2 The relevant description of the implementation method in S210 will not be repeated here.

[0138] S720: Acquire the virtual image content, virtual image position, and display content and position of each screen in the vehicle, and determine the target screen.

[0139] In an embodiment of the present application, the screen in the vehicle that is consistent with the virtual image content may be determined as the target screen according to the virtual image content; or the target screen may be determined based on the imaging position of the virtual image and the positions of each screen in the vehicle.

[0140] Optionally, the implementation of S720 can be found in Figure 2 The relevant description of the implementation method in S220 will not be repeated here.

[0141] S730, determine whether the risk level is less than the preset risk level; if so, execute S750; if not, execute S740.

[0142] In an embodiment of the present application, it is determined whether the risk level is less than the preset risk level. If the risk level is less than the preset risk level, the virtual image does not interfere with the driver's field of view. At this time, the parameters of the target screen are not adjusted, the current configuration parameters are determined as the target configuration parameters, and S750 is executed; if the risk level is greater than or equal to the preset risk level, the virtual image interferes with the driver's field of view. At this time, it is necessary to adjust the parameters of the target screen, determine the configuration parameters corresponding to the risk level as the target configuration parameters, and execute S740.

[0143] Optionally, the implementation of S730 can be found in Figure 2 The relevant description of the implementation method in S230 will not be repeated here.

[0144] S740: Determine the configuration parameters corresponding to the risk level as target configuration parameters.

[0145] Exemplarily, a mapping relationship between risk level and configuration parameters can be preset, and the target configuration parameters can be determined according to the mapping relationship between the current risk level, risk level and configuration parameters. As shown in Table 1, when the risk level is 2, the virtual image interferes with the driver's field of view, but the occlusion area is not large, and the target screen needs to be turned off to extinguish 20% of the entire screen display area; when the risk level is 3, the virtual image interferes with the driver's field of view, and the occlusion area is large, and the target screen needs to be turned off to extinguish 30% of the entire screen display area.

[0146] For example, Figure 3 As shown in (c) in FIG. 3 , if it is detected that the user selects the custom control 304, a preset configuration parameter range may be provided to the user for the user to select within the preset configuration parameter range, such as Figure 3 As shown in (e) in FIG. 5 , the configuration parameters selected by the user are determined as the target configuration parameters.

[0147] For example, if it is detected that the user selects to determine the target configuration parameter within the preset configuration parameter range, that is, it is detected that the user selects the custom control 304, the predicted risk information can be output, such as Figure 5 As shown in (b) in the figure; the user sets the screen configuration parameters in the custom area, such as adjusting the screen off ratio or brightness parameters; intelligent prediction is performed based on the configuration parameters adjusted by the user in the custom area, the risk situation of the target screen after displaying with the configuration parameters is simulated, and an intelligent prediction result 503 (i.e., predicted risk information) is generated, and a suggestion 504 is generated based on the intelligent prediction result 503.

[0148] Optionally, the implementation of S740 can be found in Figure 2 The relevant description of the implementation method in S230 will not be repeated here.

[0149] S750: Determine the current configuration parameters as the target configuration parameters.

[0150] Optionally, the implementation of S750 can be found in Figure 2 The relevant description of the implementation method in S230 will not be repeated here.

[0151] S760. Control the target screen display based on the target configuration parameters.

[0152] In another embodiment, when a virtual image caused by a screen in the vehicle is detected on the left side window of the driver, a prompt message is output, which is used to prompt the user that the screen in the vehicle has generated side window imaging, causing driving risks, and prompt the user to adjust the configuration parameters of the screen; if it is detected that the user has no operation within a preset time, the target screen is not adjusted; if it is detected that the user selects the confirmation control 302, the risk level is determined, and the target configuration parameters are obtained based on the risk level, the target screen is controlled to display with the target configuration parameters, and the selection information is output, such as Figure 5 As shown in (a) in .

[0153] In another embodiment, when it is detected that the driver's head moves toward the direction of the driver's left window, the target screen is controlled to display with the target configuration parameters.

[0154] Optionally, the implementation of S760 can be found in Figure 2 The relevant description of the implementation method in S240 will not be repeated here.

[0155] In the above embodiment, by detecting the target virtual image on the target window of the vehicle, the risk level of interference of the virtual image on the driver's field of view can be evaluated, and the configuration parameters of the target screen can be determined according to the risk level, and the target screen can be controlled for display based on the target configuration parameters; in the above scheme, since the target configuration parameters are determined based on the risk level, different target configuration parameters can be determined for situations with different risk levels, and the configuration parameters can be flexibly formulated, so that when the risk level is low, the configuration parameters of the screen can be kept small to avoid interference to users who are watching the screen; when the risk level is high, the configuration parameters of the screen can be adjusted to reduce the impact of the screen on the driver's field of view, thereby improving driving safety; since the target screen is controlled for display based on the target configuration parameters, the adverse impact of the virtual image on the driver's field of view can be weakened, making the driver's field of view clearer, thereby improving driving experience and safety.
