Description

Technical Field

[0001] The present application relates to the field of smart cockpits in vehicles, and more specifically, to a control method for a vehicle ceiling screen, a ceiling screen, a control device, and a vehicle in the field of vehicle control technology. Background Art

[0002] With the development of vehicle control technology, vehicles may be equipped with ceiling screens. In the prior art, when a ceiling screen is folded, if the user clicks the screen or places their hand on the screen, there is a risk of pinching the user.

[0003] Therefore, how to reduce the risk of users being pinched by ceiling screens and improve user experience is a problem that needs to be solved at present. Summary of the Invention

[0004] The present application provides a control method for a vehicle ceiling screen, a ceiling screen, a control device, and a vehicle. The method can reduce the risk of a user being pinched by the ceiling screen.

[0005] In a first aspect, a method for controlling a vehicle ceiling screen is provided, wherein the ceiling screen includes a first sub-frame, and the first sub-frame is configured with a first touch device with adjustable sensitivity. The method includes:

[0006] In response to a folding signal of the ceiling screen, obtaining a current angle of the ceiling screen, where the current angle refers to an angle between a display screen of the ceiling screen and a top of the vehicle;

[0007] Determine target sensitivity based on current angle;

[0008] The first touch device is controlled to operate at a target sensitivity, and an anti-pinch function of the ceiling screen is triggered when the first touch device detects a touch operation.

[0009] In an embodiment of the present application, since the target sensitivity of the first touch device with adjustable sensitivity is determined by the current angle between the display screen of the ceiling screen and the top of the vehicle, the working sensitivity of the first touch device can be adaptively adjusted for different angles; compared with the prior art, the touch device of the ceiling screen is arranged in the display screen area and is only used to detect display interaction operations, and cannot protect the ceiling screen from pinching the user during the folding process; the present solution sets a touch device at the frame of the ceiling screen, which can sense the user's touch operation during the folding process of the ceiling screen, thereby triggering the anti-pinch function in time when the user approaches, reducing the risk of the ceiling screen pinching the user. Furthermore, the touch device in this solution is a touch device with adjustable sensitivity. By obtaining the current angle between the display screen of the ceiling screen and the top of the vehicle, the working sensitivity of the touch device is dynamically adjusted according to the angle. Since the risk of pinching the ceiling screen is different at different angles, the smaller the angle, the greater the risk of the user being pinched. Therefore, this solution can dynamically adjust the sensitivity according to the current angle of the ceiling screen, and determine the sensitivity of the touch device based on the pinching risk at the current angle, which can reduce the risk of the user being pinched by the ceiling screen, thereby improving the user experience.

[0010] It should be understood that the display screen area refers to the area on the ceiling screen used for image display or video display; the sub-frame in the embodiment of the present application refers to the area of non-display structure surrounding the display screen, which does not have image display function and is not a touch interaction area in the traditional sense.

[0011] It should also be understood that the first frame may be a frame located at the bottom edge of the display screen. In conjunction with the first aspect, in some possible implementations, determining the target sensitivity based on the current angle includes:

[0012] When the current angle is greater than a first threshold, determining the first sensitivity as the target sensitivity;

[0013] When the current angle is greater than or equal to the second threshold and less than or equal to the first threshold, determining the second sensitivity as the target sensitivity;

[0014] When the current angle is less than the second threshold, determining the third sensitivity as the target sensitivity;

[0015] The first threshold is greater than the second threshold, the third sensitivity is higher than the second sensitivity, and the second sensitivity is higher than the first sensitivity.

[0016] In an embodiment of the present application, by setting multiple angle thresholds, when the current angle is greater than the first angle threshold, the first sensitivity is determined as the target sensitivity, so that when the risk of pinching the user is small, the first touch device is controlled to operate at low sensitivity, thereby avoiding false detection causing the ceiling screen to falsely trigger the anti-pinch function; when the current angle is greater than or equal to the second threshold and less than or equal to the first threshold, the first touch device is controlled to operate at medium sensitivity, thereby timely detecting the user's touch operation while avoiding false detection that affects the user's usage experience; when the current angle is less than the second threshold, the first touch device is controlled to operate at high sensitivity, thereby timely detecting the user's touch operation when the angle between the ceiling screen and the top is small, thereby preventing the user from being pinched; the above scheme can divide the folding angle of the ceiling screen into multiple intervals, match different sensitivities to the first touch device for different intervals, realize hierarchical control of sensitivity, take into account the accuracy of user touch operation recognition and the need to prevent false touches, reduce the risk of users being pinched by the ceiling screen, and improve user experience.

[0017] In combination with the first aspect and the above implementations, in some possible implementations, the ceiling screen includes a second sub-frame, the second sub-frame is configured with a second touch device, and the method further includes:

[0018] In response to the folding signal of the ceiling screen, the second touch device is controlled to operate.

[0019] In an embodiment of the present application, the ceiling screen includes a second sub-frame, which is equipped with a second touch device. In response to the folding signal of the ceiling screen, the second touch device is controlled to operate. On the basis of detecting the touch operation by the first touch device, the risk of the user being pinched by the ceiling screen can be further reduced, thereby improving the user experience.

[0020] In one implementation, the second touch control device may be a touch control device with a fixed sensitivity; or the second touch control device may be a second touch control device with an adjustable sensitivity.

[0021] In one implementation, the second touch device is a touch device located on the left and right borders of the display screen. In combination with the first aspect and the above implementation, in some possible implementations, the ceiling screen includes a second sub-frame connected to the first sub-frame, and the second sub-frame is configured with the second touch device. The method further includes:

[0022] determining a current state of the second touch device based on the current angle;

[0023] The current state is either a disabled state or an enabled state.

[0024] In an embodiment of the present application, the second touch device is determined to be in a disabled state or an enabled state based on the current angle, and the activation timing of the second touch device can be determined according to the current angle, thereby avoiding the false triggering of the anti-pinch function due to accidental touch, and reducing the risk of the ceiling screen pinching the user.

[0025] In combination with the first aspect and the above implementations, in some possible implementations, determining the current state of the second touch device based on the current angle includes:

[0026] When the current angle is greater than a first threshold, determining the disabled state as the current state of the second touch device;

[0027] When the current angle is less than or equal to the first threshold, the activated state is determined as the current state of the second touch device.

[0028] In an embodiment of the present application, the second touch device is disabled when the current angle is greater than the first threshold. Since it is usually difficult for the user to touch the edge area where the second touch device is located when the angle is large, keeping the second touch device in a disabled state at this time can reduce the false triggering of the anti-pinch function due to unexpected contact or accidental touch; the second touch device is started when the current angle is less than or equal to the first threshold. Since the ceiling screen is close to the folded position when the angle is small, the risk of the ceiling screen pinching the user's hand is greater. Therefore, when the current angle is less than or equal to the first threshold, the user's touch operation can be detected in time and the anti-pinch function is triggered, thereby reducing the risk of the user being pinched by the ceiling screen.

[0029] In a second aspect, a ceiling screen is provided, comprising:

[0030] The rotating shaft and the housing, and the housing and the rotating shaft are rotatably connected;

[0031] The ceiling screen has a display surface;

[0032] The housing includes a first sub-frame located on the display surface, and the first sub-frame is equipped with a first touch device with adjustable sensitivity.

[0033] In an embodiment of the present application, by rotatably connecting the shell of the ceiling screen with the rotating shaft, the ceiling screen can be folded or unfolded on the top of the vehicle, thereby improving the space utilization and convenience inside the vehicle cabin; the ceiling screen has a display surface, and since the first sub-frame of the display surface is configured with a first touch device with adjustable sensitivity, the ceiling screen can sense the user's touch operation during movement and be flexibly configured according to different scenarios, thereby reducing the risk of the ceiling screen pinching the user and improving the user experience.

[0034] In one implementation, the first sub-frame may refer to a frame located at the lower edge of the display surface.

[0035] It should be understood that the display screen area refers to the area on the ceiling screen used for image display or video display; the sub-frame in the embodiment of the present application refers to the area of non-display structure surrounding the display screen, which does not have image display function and is not a touch interaction area in the traditional sense.

[0038] In an embodiment of the present application, the first sub-frame of the ceiling screen is configured with a first touch device with adjustable sensitivity, and a second touch device; by configuring touch devices on multiple sub-frames, the ceiling screen can detect touch operations at the sub-frames, thereby reducing the risk of the ceiling screen pinching the user and improving the user experience.

[0039] It should be understood that the second sub-frame refers to the frame located at the left and right edges of the display surface.

[0040] In conjunction with the second aspect, in some possible implementations, the second touch device is disposed away from the vehicle roof.

[0041] In an embodiment of the present application, by designing the second touch device away from the roof, the second control device can be configured at a position where the risk of the ceiling screen pinching the user is higher, thereby setting the touch device in the corresponding area, reducing the risk of the ceiling screen pinching the user, and thus improving the user experience.

[0044] The processing module is used to determine the target sensitivity based on the current angle; control the first touch device to operate at the target sensitivity, and trigger the anti-pinch function of the ceiling screen when the first touch device detects a touch operation.

[0045] In combination with the third aspect, in certain implementations of the third aspect, the processing module is specifically used to: when the current angle is greater than a first threshold, determine the first sensitivity as the target sensitivity; when the current angle is greater than or equal to the second threshold and less than or equal to the first threshold, determine the second sensitivity as the target sensitivity; when the current angle is less than the second threshold, determine the third sensitivity as the target sensitivity; wherein, the first threshold is greater than the second threshold, the third sensitivity is higher than the second sensitivity, and the second sensitivity is higher than the first sensitivity.

[0058] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this 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 this application, "multiple" means two or more than two.

[0059] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0060] The vehicle can be equipped with a ceiling screen, such as Figure 1 As shown, Figure 1 It is a scene diagram of a vehicle provided in an embodiment of the present application; scene 100 may include 101, and 101 may be a ceiling screen.

[0061] The ceiling screen 101 can be an in-vehicle entertainment display device, which is usually connected to the roof frame through a mechanical structure. The connection between the ceiling screen 101 and the roof frame can be equipped with a rotating shaft to realize the folding or unfolding of the ceiling screen 101. When the screen is in the closed state, it is adsorbed on the roof and can be fixed to the roof interior surface by magnetic adsorption or mechanical locking device, so as not to affect the aesthetics of the whole vehicle and the space utilization efficiency; when the system receives the user's opening command, the ceiling screen can automatically flip to the unfolded state, showing a complete display area for the rear passengers to watch. When the ceiling screen 101 responds to the folding signal, the ceiling screen 101 begins to fold, such as Figure 1 As shown in (a), as the folding angle θ decreases, if it is detected that the user's hand is touching the ceiling screen, if no anti-pinch measures are taken at this time, there is a risk that the ceiling screen 101 will pinch the user's hand.

[0062] In the prior art, the ceiling screen can be Figure 1As shown in 101 in (b) of the figure, 102 is the screen display area of the ceiling-mounted screen. Touch detection of the user's hand is not performed, resulting in the risk of the ceiling-mounted screen pinching the user. Because the ceiling-mounted screen needs to complete mechanical movement during folding or unfolding, its edge may approach the passenger area during the movement path. Especially when the screen is folded close to the roof, if a passenger's finger (especially a child's small finger) accidentally places it on the edge of the screen, it is very easy to be pinched by the moving screen.

[0063] In view of this, an embodiment of the present application provides a control method for a vehicle ceiling screen, a ceiling screen, a control device, and a vehicle. In response to a folding signal of the ceiling screen, the current angle of the ceiling screen is obtained, where the current angle refers to the angle between the display screen of the ceiling screen and the top of the vehicle; based on the current angle, the target sensitivity is determined; the first touch device is controlled to operate at the target sensitivity, and the anti-pinch function of the ceiling screen is triggered when the first touch device detects a touch operation. Since this solution determines the target sensitivity based on the current angle, it is possible to adaptively adjust the working sensitivity of the first touch device for different angles; compared to the prior art, when the ceiling screen is folded, the ceiling screen uses a fixed sensitivity, which may lead to frequent false touches at large angles, and cannot detect the user in time when the angle is small, resulting in a greater risk of pinching the user; this solution can dynamically adjust the sensitivity according to the current angle of the ceiling screen, and determine the sensitivity of the touch device based on the pinching risk at the current angle, which can reduce the risk of the user being pinched by the ceiling screen, thereby improving the user experience.

[0064] It should be understood that in the embodiment of the present application, the ceiling screen includes a housing, a rotating shaft and a display screen, and the ceiling screen has a display surface; the housing includes a plurality of sub-frames located on the display surface, and the plurality of sub-frames are arranged around the display screen. Among them, the first sub-frame can be any one of the plurality of sub-frames. For example, the first sub-frame can be as follows Figure 2 203 shown in (a) of FIG. The second sub-frame may be one or more frames other than the first sub-frame in the plurality of sub-frames. For example, the second sub-frame may be as follows Figure 2 201 and 202 shown in (a) in FIG.

[0065] Figure 2 Schematic diagram of a ceiling screen display surface provided in an embodiment of the present application. Figure 2 As shown in (a), 200 is the display surface of the ceiling screen, 201, 202, 203 and 204 are frames located on the display surface, namely the left frame, right frame, bottom frame and top frame respectively; the display surface and the four frames are all located on the shell of the ceiling screen; the top frame is physically connected to the hinge of the ceiling screen.

[0066] Since the distance between the upper frame and the top of the vehicle is very close, the probability of the upper frame pinching the user when the ceiling screen is folded is extremely low. Therefore, touch devices can be configured at 201, 202 and 203 respectively to detect the user's fingers or other objects during the folding process of the ceiling screen, and to take anti-pinch function in time when the user's fingers or other objects are detected.

[0067] In one embodiment, if Figure 2 As shown in (b), 205 is the display surface of the ceiling screen. The display surface and four frames are all located on the shell of the ceiling screen; the upper frame is physically connected to the rotation axis of the ceiling screen.

[0068] Since the upper frame 209 and the areas of the left and right frames close to the top of the vehicle are very close to the top of the vehicle, the probability of the upper frame pinching the user when the ceiling screen is folded is extremely low. Therefore, touch devices can be configured at 206, 207 and 208 respectively to detect the user's fingers or other objects during the folding process of the ceiling screen, and to take anti-pinch functions in time when the user's fingers or other objects are detected.

[0069] The touch devices are arranged at positions 206 and 207 on the left and right frames away from the top of the vehicle, and the touch device is arranged at the middle position 208 of the lower frame, which can save material and energy loss while preventing the risk of pinching the user.

[0070] Optionally, the touch devices of the left and right frames can be configured over the entire length of the left and right frames, such as Figure 2 Alternatively, the touch devices of the left and right frames can also be arranged in the area of the left and right frames away from the roof, such as Figure 2 As shown in 206 and 207 in (b) of FIG. The touch device of the lower frame can be configured in the entire length area of the lower frame, such as Figure 2 Alternatively, the touch device of the lower frame can be configured in a partial area of the lower frame, such as Figure 2 As shown in 208 in (b).

[0071] Optionally, when the touch device is only configured in a partial area of the frame, it can be adjusted according to the structure inside the cabin, for example, it can be configured in the middle area or other areas of the frame.

[0072] The following combination Figure 3 A control method for a vehicle ceiling screen provided in an embodiment of the present application is described in detail.

[0073] Figure 3 This is a schematic flow chart of a control method for a vehicle ceiling screen provided in an embodiment of the present application. Figure 3As shown, the method 300 includes S310 to S330, and S310 to S330 are described in detail below.

[0074] For example, Figure 3 The method 300 shown may be executed by a vehicle; or, executed by a processor in a vehicle; or, executed by a chip mounted in a processor in a vehicle; or, executed by a software platform integrated in an electronic device.

[0075] S310 : Responding to a folding signal of the ceiling screen, obtaining a current angle of the ceiling screen.

[0076] In the embodiment of the present application, the ceiling screen includes a first sub-frame, which can be Figure 2 203 in (a) or can be Figure 2 208 in (b) of .

[0077] The current angle refers to the angle between the display screen of the ceiling screen and the top of the vehicle.

[0078] For example, the current angle is Figure 1 The folding angle θ in (a) is shown in FIG.

[0079] For example, if it is detected that the user has issued an instruction to close the ceiling screen, the ceiling screen is controlled to fold toward the top of the vehicle through the hinge, and the angle sensor configured on the hinge of the ceiling screen is used to detect the rotation angle of the hinge of the ceiling screen, and the angle between the display screen of the current ceiling screen and the top of the vehicle is determined based on the rotation angle of the hinge.

[0080] For example, it is detected that the user issues a voice command: close the ceiling screen; generate a folding signal for the ceiling screen, control the rotation axis of the ceiling screen to rotate, and fold the surface where the screen is located toward the top of the vehicle.

[0081] Optionally, when it is detected that the user issues an instruction to close the ceiling screen, a folding signal for the ceiling screen is generated; wherein, the instruction can be detected through voice recognition, text input or key detection.

[0082] S320: Determine target sensitivity based on the current angle.

[0083] In an embodiment of the present application, the target sensitivity of the touch device configured in the first sub-frame is determined based on the angle between the display screen of the ceiling screen and the top of the vehicle.

[0084] It should be understood that the first sub-frame can be Figure 2 203 in (a) of the above, or Figure 2 208 in (b) of .

[0085] In one implementation, the method includes:

[0086] When the current angle is greater than the first threshold, the first sensitivity is determined as the target sensitivity; when the current angle is greater than or equal to the second threshold and less than or equal to the first threshold, the second sensitivity is determined as the target sensitivity; when the current angle is less than the second threshold, the third sensitivity is determined as the target sensitivity.

[0087] Among them, the first threshold is greater than the second threshold, the first threshold can be set to 45 degrees, and the second threshold can be set to 25 degrees; the third sensitivity is higher than the second sensitivity, and the second sensitivity is higher than the first sensitivity.

[0088] For example, when the current angle is detected to be 50 degrees, it is greater than the first threshold, and the target sensitivity is determined to be level 2, and the touch device configured at the lower edge of the ceiling screen is controlled to operate at sensitivity level 2; when the current angle is detected to be 30 degrees, it is greater than the second threshold and less than the first threshold, and level 5 is determined as the target sensitivity, and the touch device configured at the lower edge of the ceiling screen is controlled to operate at sensitivity level 5; when the current angle is detected to be 20 degrees, it is less than the second threshold, and level 8 is determined as the target sensitivity, and the touch device configured at the lower edge of the ceiling screen is controlled to operate at sensitivity level 8.

[0089] It should be understood that the sensitivity range of the target touch device may include levels 0 to 10. The higher the sensitivity level, the more sensitive the touch device is and the larger the distance range that can be detected.

[0090] For example, when the current angle is detected to be greater than 45 degrees, level 2 is determined as the target sensitivity, and the touch devices configured on the bottom, left, and right edges of the ceiling screen are all controlled to operate at sensitivity level 2. When the current angle is detected to be 30 degrees, which is greater than the second threshold and less than the first threshold, level 5 is determined as the target sensitivity, and the touch devices configured on the bottom, left, and right edges of the ceiling screen are all controlled to operate at sensitivity level 5. When the current angle is detected to be 20 degrees, which is less than the second threshold, level 8 is determined as the target sensitivity, and the touch devices configured on the bottom, left, and right edges of the ceiling screen are all controlled to operate at sensitivity level 8.

[0091] It should be understood that the first threshold value is 45 degrees and the second threshold value is 25 degrees. Alternatively, the first threshold value may be 30 degrees, 40 degrees, 50 degrees, etc.; and the second threshold value may be 15 degrees, 20 degrees, 30 degrees, etc. This application does not impose any limitation on the specific values of the first and second threshold values.

[0092] Optionally, when determining the target sensitivity, when the current angle is greater than the first threshold, the first percentage value of the maximum sensitivity can be determined as the first sensitivity; when the current angle is greater than or equal to the second threshold and less than or equal to the first threshold, the second percentage value of the maximum sensitivity can be determined as the second sensitivity; when the current angle is less than the second threshold, the third percentage value of the maximum sensitivity can be determined as the third sensitivity.

[0093] For example, the first percentage value is 25%, the first sensitivity may refer to 25% of the maximum sensitivity, that is, the first sensitivity may indicate (low sensitivity); the second percentage value is 50%, the second sensitivity may refer to 50% of the maximum sensitivity, that is, the second sensitivity may indicate (medium sensitivity); the third percentage value is 75%, the third sensitivity may refer to 75% of the maximum sensitivity, that is, the third sensitivity may indicate (draft sensitivity).

[0094] Optionally, in an embodiment, when the sensitivity of the first touch device can be freely adjusted, the target sensitivity can be obtained according to the current angle.

[0095] In an embodiment of the present application, the sensitivity of the touch device can dynamically increase as the angle between the display screen and the roof decreases during the folding process of the ceiling screen.

[0096] For example, the target sensitivity may be inversely proportional to the current angle, for example, target sensitivity = k × current angle + b; where k and b are adjustable parameters, for example, k may be set to -0.5, and b may be set to 20. For example, when the current angle is 30 degrees, the calculated target sensitivity is level 5; when the current angle is 20 degrees, the calculated target sensitivity is level 10.

[0097] It should be understood that the above is an example to illustrate the relationship between target sensitivity and the current angle. The embodiment of the present application only limits the target sensitivity to be inversely proportional to the current angle, and does not limit how to determine the target sensitivity based on the current angle.

[0098] In the above implementation, by setting multiple angle thresholds, when the current angle is greater than the first angle threshold, the first sensitivity is determined as the target sensitivity. When the risk of pinching the user is small, the first touch device is controlled to operate at low sensitivity, thereby avoiding false detection and causing the ceiling screen to falsely trigger the anti-pinch function; when the current angle is greater than or equal to the second threshold and less than or equal to the first threshold, the first touch device is controlled to operate at medium sensitivity, thereby timely detecting the user's touch operation while avoiding false detection and affecting the user's usage experience; when the current angle is less than the second threshold, the first touch device is controlled to operate at high sensitivity, thereby timely detecting the user's touch operation when the angle between the ceiling screen and the top is small, thereby preventing the user from being pinched; the above scheme can divide the folding angle of the ceiling screen into multiple intervals, match different sensitivities to the first touch device for different intervals, realize graded control of sensitivity, take into account the accuracy of user touch operation recognition and the need to prevent false touches, reduce the risk of users being pinched by the ceiling screen, and improve user experience.

[0099] Optionally, in another implementation, the first touch device includes three devices with different touch sensitivities.

[0100] Exemplarily, the first touch device includes a first target touch device, a second target touch device, and a third target touch device. The sensitivity of the first target touch device is level 2, the sensitivity of the second target touch device is level 5, and the sensitivity of the third target touch device is level 8. Specifically, when it is detected that the current angle is 50 degrees, which is greater than a first threshold, the first target touch device is controlled to be in an active state, and the second and third target touch devices are in a disabled state; when it is detected that the current angle is 30 degrees, which is greater than the second threshold and less than the first threshold, the second target touch device is controlled to be in an active state, and the first and third target touch devices are in a disabled state; when it is detected that the current angle is 20 degrees, which is less than the second threshold, the third target touch device is controlled to be in an active state, and the second and first target touch devices are in a disabled state.

[0101] S330: Control the first touch device to operate at the target sensitivity, and detect that the touch operation triggers the anti-pinch function of the ceiling screen.

[0102] In an embodiment of the present application, the first touch device of the ceiling screen is controlled to operate at a target sensitivity, and if a touch operation is detected when the first touch device operates at the target sensitivity, the anti-pinch function of the ceiling screen is triggered.

[0103] Among them, the anti-pinch function can pause the folding of the ceiling screen and output a prompt message to remind the user that the ceiling screen is folding and not to place hands on the ceiling screen.

[0104] Optionally, the ceiling screen may have a vibration function, and when the anti-pinch function of the ceiling screen is triggered, the ceiling screen may turn on the vibration function.

[0105] For example, when it is detected that the current angle is 50 degrees, which is greater than the first threshold, level 2 is determined as the target sensitivity level, and the touch device configured at the lower edge of the ceiling screen is controlled to operate at sensitivity level 2; when the touch device at the lower edge is operating at sensitivity level 2, it is detected that the user's hand is detected within the sensitivity range. At this time, it is determined that a touch operation is detected, and the folding of the ceiling screen is stopped immediately, and a prompt message is output to prompt the user to stop touching the screen, and the ceiling screen is controlled to vibrate.

[0106] Optionally, the prompt information can be broadcast in the form of voice through the audio equipment configured in the vehicle to prompt the user to stop touching the screen.

[0107] In one implementation, the ceiling screen includes a second sub-frame, the second sub-frame is configured with a second touch device, and the above method further includes:

[0108] It should be understood that the second sub-frame can be Figure 2 201 and 202 in (a), or Figure 2 206 and 207 in (b).

[0109] In response to the folding signal of the ceiling screen, the second touch device is controlled to operate.

[0110] For example, in addition to the touch device at the bottom edge of the ceiling screen, second touch devices may be configured at the left and right edges. When a folding signal of the ceiling screen is detected, the second touch devices are controlled to operate with a fixed sensitivity value.

[0111] For example, in addition to the touch device at the bottom edge of the ceiling screen, second touch devices may be configured at the left and right edges. When a folding signal of the ceiling screen is detected, the second touch devices are controlled to operate at the target sensitivity value determined in S320.

[0112] Optionally, the touch device can be a capacitive touch detection device. When a user's finger or other object is detected near the touch area, the electric field distribution in the area is changed, causing the capacitance to change. The sensitivity of the touch device can be adjusted by setting the capacitance threshold to different values.

[0113] Alternatively, the touch device may be an infrared touch device. The touch device includes an array of sensors at the screen border that transmit or receive infrared light, forming an infrared grid. When a user's finger blocks the infrared beam, a touch operation is determined. A touch operation can be determined by detecting the location of the interrupted beam.

[0114] It should be understood that the present application does not limit the detection method of the touch device.

[0115] In the above implementation, the ceiling screen includes a second sub-frame, which is equipped with a second touch device. In response to the folding signal of the ceiling screen, the second touch device is controlled to operate. On the basis of detecting the touch operation by the first touch device, the risk of the user being pinched by the ceiling screen can be further reduced, thereby improving the user experience.

[0116] In one implementation, the ceiling screen includes a second sub-frame connected to the first sub-frame, the second sub-frame is configured with a second touch device, and further includes:

[0117] Based on the current angle, a current state of the second touch device is determined.

[0118] The current state is either disabled or enabled. The enabled state means the touch device is in an operational state. At this point, the touch device can monitor the user's touch behavior in real time and trigger corresponding logic when a touch operation is detected, such as triggering an anti-pinch function. The disabled state means the touch device is in an inoperative or off state. At this point, even if the user touches the corresponding area of the touch device, the operation will not be responded to, and the touch signal will not be collected or processed.

[0119] Exemplarily, when it is detected that the current angle is less than or equal to 45, it is determined that the second touch device is in the on state.

[0120] In the above implementation, the second touch device is determined to be in a disabled state or an enabled state based on the current angle, and the activation timing of the second touch device can be determined according to the current angle, thereby avoiding the false triggering of the anti-pinch function due to accidental touch, and reducing the risk of the ceiling screen pinching the user.

[0121] In one implementation, the method includes:

[0122] When the current angle is greater than the first threshold, the disabled state is determined as the current state of the second touch device; when the current angle is less than or equal to the first threshold, the enabled state is determined as the current state of the second touch device.

[0123] For example, when it is detected that the current angle is greater than 45 degrees, the second touch device configured on the left and right edges of the ceiling screen is in a disabled state, that is, no touch operation is detected at this time; when it is detected that the current angle is less than or equal to 45 degrees, the second touch device configured on the left and right edges of the ceiling screen is in an activated state, that is, touch operations are detected at this time.

[0124] In the above implementation, the second touch device is disabled when the current angle is greater than the first threshold. Since it is usually difficult for the user to touch the edge area where the second touch device is located when the angle is large, keeping the second touch device in a disabled state at this time can reduce the false triggering of the anti-pinch function due to unexpected contact or accidental touch; the second touch device is started when the current angle is less than or equal to the first threshold. Since the ceiling screen is close to the folded position when the angle is small, the risk of the ceiling screen pinching the user's hand is greater. Therefore, when the current angle is less than or equal to the first threshold, the user's touch operation can be detected in time and the anti-pinch function is triggered, thereby reducing the risk of the user being pinched by the ceiling screen. In the above embodiment, the target sensitivity of the first touch device with adjustable sensitivity is determined by the current angle between the display screen of the ceiling screen and the top of the vehicle, thereby enabling adaptive adjustment of the operating sensitivity of the first touch device for different angles. Compared to the prior art, the touch device of the ceiling screen is configured in the display area and is only used to detect display interaction operations, and cannot protect the ceiling screen from pinching the user during folding. In contrast, the present solution provides a touch device at the frame of the ceiling screen, which can sense the user's touch operation during the folding process of the ceiling screen, thereby promptly triggering the anti-pinch function when the user approaches, reducing the risk of the ceiling screen pinching the user. Furthermore, the touch device in the present solution is a touch device with adjustable sensitivity. By obtaining the current angle between the display screen of the ceiling screen and the top of the vehicle, the operating sensitivity of the touch device is dynamically adjusted according to the angle. Since the risk of pinching the user varies at different angles of the ceiling screen, the smaller the angle, the greater the risk of pinching the user. Therefore, the present solution can dynamically adjust the sensitivity according to the current angle of the ceiling screen, determine the sensitivity of the touch device based on the pinching risk at the current angle, and reduce the risk of the user being pinched by the ceiling screen, thereby improving the user experience.

[0125] The following combination Figure 4 Another method for controlling a vehicle ceiling screen provided in an embodiment of the present application is described in detail.

[0126] Figure 4 This is a schematic flow chart of another method for controlling a vehicle ceiling screen provided in an embodiment of the present application. Figure 4 As shown, the method 400 includes S401 to S406, and S401 to S406 are described in detail below.

[0127] For example, Figure 4 The illustrated method 400 may be executed by a vehicle; or, executed by a processor in a vehicle; or, executed by a chip mounted in a processor in a vehicle; or, executed by a software platform integrated in an electronic device.

[0128] S401 : In response to a folding signal of the ceiling screen, control the ceiling screen to fold.

[0129] For example, if it is detected that the user issues an instruction to close the ceiling screen, the ceiling screen is controlled to fold toward the top of the vehicle via the rotating shaft.

[0130] For example, it is detected that the user issues a voice command: close the ceiling screen; generate a folding signal for the ceiling screen, control the rotation axis of the ceiling screen to rotate, and fold the surface where the screen is located toward the top of the vehicle.

[0131] Optionally, when it is detected that the user issues an instruction to close the ceiling screen, a folding signal for the ceiling screen is generated; wherein, the instruction can be detected through voice recognition, text input or key detection.

[0132] Optionally, the implementation of S401 can be found in Figure 3 The relevant description in S310 is not repeated here.

[0133] S402: During the folding process of the ceiling screen, detecting the folding angle of the ceiling screen.

[0134] The folding angle refers to the angle between the display screen of the ceiling screen and the top of the vehicle.

[0135] In an embodiment of the present application, there may be a risk of pinching the user's fingers during the folding process of the ceiling screen; since the pinching risk is different at different folding angles, it is necessary to detect the folding angle of the ceiling screen to implement different anti-pinch strategies.

[0136] Exemplarily, the ceiling screen may be configured with an angle sensor for detecting the angle between the display screen of the ceiling screen and the top of the vehicle.

[0137] Optionally, an angle sensor may be disposed on the rotation shaft of the ceiling screen, capable of detecting the rotation angle of the rotation shaft. Based on the rotation angle of the rotation shaft, the angle between the display screen of the ceiling screen and the top of the vehicle may be determined.

[0138] Optionally, the implementation of S402 can be found in Figure 3 The relevant description in S310 is not repeated here.

[0139] S403: If it is detected that the folding angle is greater than 45 degrees, the touch device at the bottom edge of the ceiling screen is controlled to start with low sensitivity, and the left edge touch device and the right edge touch device remain turned off.

[0140] In an embodiment of the present application, when it is detected that the folding angle is greater than 45 degrees (the first threshold value), the risk of pinching the user is smaller because there is a larger space between the screen of the ceiling-mounted screen and the top of the vehicle. Moreover, among the lower edge, left edge and right edge, the risk of pinching the user on the lower edge is relatively greater than that on the left and right edges. Therefore, when the risk of pinching the user on the ceiling-mounted screen is smaller, only the touch device on the lower edge is controlled to start, and the touch devices on the left and right edges remain turned off.

[0141] For example, when it is detected that the folding angle of the ceiling screen is greater than 45 degrees, the touch device at the bottom edge of the ceiling screen is controlled to be turned on, and the sensitivity of the touch device at the bottom edge is adjusted to a low level, and the left edge touch device and the right edge touch device remain in the off state.

[0142] Optionally, when it is detected that the folding angle is greater than a first threshold, the touch device at the bottom edge of the ceiling screen is controlled to start with low sensitivity.

[0143] Optionally, the sensitivity of the touch device can be used to represent touch distance detection; the lower the sensitivity of the touch device, the closer the user's hand or other object needs to be to the touch device, or even directly in contact with the touch device to be recognized by the touch device.

[0144] Optionally, 45 degrees is an example of the first threshold in an embodiment of the present application, and the present application does not limit the angle value of the angle threshold.

[0145] Optionally, in one embodiment, if it is detected that the folding angle is greater than 45 degrees, the bottom edge touch device, the left edge touch device, and the right edge touch device of the ceiling screen are controlled to start with low sensitivity.

[0146] Optionally, in another embodiment, the first touch device includes three devices with different touch sensitivities.

[0147] Exemplarily, the first touch device includes a first target touch device, a second target touch device, and a third target touch device. The sensitivity of the first target touch device is level 2, the sensitivity of the second target touch device is level 5, and the sensitivity of the third target touch device is level 8. Specifically, if the folding angle is greater than 45 degrees, the first target touch device is controlled to be in an active state, and the second and third target touch devices are controlled to be in a disabled state.

[0148] Optionally, the implementation of S403 can be found in Figure 3 The relevant description in S320 will not be repeated here.

[0149] S404: If it is detected that the folding angle is greater than 25 degrees and less than or equal to 45 degrees, control the touch device at the bottom edge of the ceiling screen to operate at medium sensitivity, and activate the left edge touch device and the right edge touch device.

[0150] In an embodiment of the present application, when it is detected that the folding angle is greater than 25 degrees (the second threshold) and less than or equal to 45 degrees (the first threshold), since there is not much space between the screen of the ceiling-mounted screen and the top of the vehicle, there is a certain risk of pinching the user. Therefore, the edge touch device is controlled to operate with medium sensitivity, and the touch devices on the left and right edges are turned on.

[0151] For example, when it is detected that the folding angle of the ceiling screen is greater than 25 degrees and less than or equal to 45 degrees, the lower edge touch device of the ceiling screen is controlled to turn on, and the sensitivity of the lower edge touch device is adjusted to a medium level, and the left edge touch device and the right edge touch device remain in the closed state.

[0152] Optionally, in one embodiment, if it is detected that the folding angle is greater than 25 degrees and less than or equal to 45 degrees, the bottom edge touch device, the left edge touch device and the right edge touch device of the ceiling screen are controlled to start with medium sensitivity.

[0153] Optionally, in another embodiment, the first touch device includes three devices with different touch sensitivities.

[0154] Exemplarily, the first touch device includes a first target touch device, a second target touch device, and a third target touch device, the first target touch device has a sensitivity level of 2, the second target touch device has a sensitivity level of 5, and the third target touch device has a sensitivity level of 8. Specifically, if a folding angle is detected to be greater than 25 degrees and less than or equal to 45 degrees, the second target touch device is controlled to be in an active state, and the first target touch device and the third target touch device are controlled to be in a disabled state.

[0155] Optionally, the implementation of S404 can be found in Figure 3 The relevant description in S320 will not be repeated here.

[0156] S405: If it is detected that the folding angle is less than or equal to 25 degrees, control the touch device at the lower edge of the ceiling screen to operate with high sensitivity, and keep the touch device at the left edge and the touch device at the right edge operating.

[0157] In an embodiment of the present application, when it is detected that the folding angle is less than or equal to 25 degrees (the second threshold), since the space between the ceiling screen and the top of the vehicle is small at this time, the risk of pinching the user is greater. Therefore, the edge touch device is controlled to operate with high sensitivity, and the touch devices on the left and right edges are turned on.

[0158] For example, when it is detected that the folding angle of the ceiling screen is less than or equal to 25 degrees, the touch device at the bottom edge of the ceiling screen is controlled to be turned on, and the sensitivity of the touch device at the bottom edge is adjusted to a high level, while the left edge touch device and the right edge touch device remain in the off state.

[0159] Optionally, in one embodiment, if it is detected that the folding angle is less than or equal to 25 degrees, the bottom edge touch device, the left edge touch device and the right edge touch device of the ceiling screen are controlled to start with high sensitivity.

[0160] Optionally, in another embodiment, the first touch device includes three devices with different touch sensitivities.

[0161] Exemplarily, the first touch device includes a first target touch device, a second target touch device, and a third target touch device. The sensitivity of the first target touch device is level 2, the sensitivity of the second target touch device is level 5, and the sensitivity of the third target touch device is level 8. Specifically, if a folding angle is detected to be less than or equal to 25 degrees, the third target touch device is controlled to be in an active state, and the first target touch device and the second target touch device are controlled to be in a disabled state.

[0162] Optionally, the implementation of S405 can be found in Figure 3 The relevant description in S320 will not be repeated here.

[0163] S406: If a user touch operation on the edge is detected, the ceiling screen is controlled to enable an anti-pinch function.

[0164] In an embodiment of the present application, the first touch device of the ceiling screen is controlled to operate at a target sensitivity, and if a touch operation is detected when the first touch device operates at the target sensitivity, the anti-pinch function of the ceiling screen is triggered.

[0165] Among them, the anti-pinch function can pause the folding of the ceiling screen and output a prompt message to remind the user that the ceiling screen is folding and not to place hands on the ceiling screen.

[0166] Optionally, the ceiling screen may have a vibration function, and when the anti-pinch function of the ceiling screen is triggered, the ceiling screen may turn on the vibration function.

[0167] For example, when it is detected that the current angle is 50 degrees, which is greater than the first threshold, level 2 is determined as the target sensitivity, and the touch device configured at the lower edge of the ceiling screen is controlled to operate at sensitivity level 2; when the touch device at the lower edge is operating at sensitivity level 2, it is detected that the user's hand is detected within the sensitivity range. At this time, it is determined that a touch operation is detected, and the folding of the ceiling screen is immediately stopped, and a prompt message is output to prompt the user to stop touching the screen, and the ceiling screen is controlled to vibrate.

[0168] Optionally, the touch device can be a capacitive touch detection device. When a user's finger or other object is detected near the touch area, the electric field distribution in the area is changed, causing the capacitance to change. The sensitivity of the touch device can be adjusted by setting the capacitance threshold to different values.

[0169] Alternatively, the touch device may be an infrared touch device. The touch device includes an array of sensors at the screen border that transmit or receive infrared light, forming an infrared grid. When a user's finger blocks the infrared beam, a touch operation is determined. A touch operation can be determined by detecting the location of the interrupted beam.

[0170] It should be understood that the present application does not limit the detection method of the touch device.

[0171] Optionally, the implementation of S406 can be found in Figure 3 The relevant description in S330 will not be repeated here.

[0172] In the above embodiment, the target sensitivity of the first touch device with adjustable sensitivity is determined by the current angle between the display screen of the ceiling screen and the top of the vehicle, thereby enabling adaptive adjustment of the operating sensitivity of the first touch device for different angles. Compared to the prior art, the touch device of the ceiling screen is configured in the display area and is only used to detect display interaction operations, and cannot protect the ceiling screen from pinching the user during folding. In contrast, the present solution provides a touch device at the frame of the ceiling screen, which can sense the user's touch operation during the folding process of the ceiling screen, thereby promptly triggering the anti-pinch function when the user approaches, reducing the risk of the ceiling screen pinching the user. Furthermore, the touch device in the present solution is a touch device with adjustable sensitivity. By obtaining the current angle between the display screen of the ceiling screen and the top of the vehicle, the operating sensitivity of the touch device is dynamically adjusted according to the angle. Since the risk of pinching the user varies at different angles of the ceiling screen, the smaller the angle, the greater the risk of pinching the user. Therefore, the present solution can dynamically adjust the sensitivity according to the current angle of the ceiling screen, determine the sensitivity of the touch device based on the pinching risk at the current angle, and reduce the risk of the user being pinched by the ceiling screen, thereby improving the user experience.
