[0025] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0026] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of vehicles.

[0027] Research has found that ceiling screens have traditionally relied mainly on their own mechanical anti-pinch triggering method. The current mechanical anti-pinch (anti-pinch can be understood as pausing the ceiling screen) requires pressing with great force for about two seconds. The current stops after the current changes, and the MCU sends a signal to the cockpit indicating that it is in an anti-pinch state. However, this method has great limitations, such as insufficient response, limited coverage of scenarios, etc. It is unable to monitor the situation in the car in real time, and there is a potential risk of pinching.

[0028] Based on this, the embodiment of the present application provides a vehicle-mounted ceiling screen control method and a vehicle. In response to the ceiling screen closing signal, the initial screen angle of the vehicle-mounted ceiling screen is determined, and the initial screen angle is the angle between the vehicle-mounted ceiling screen and the top of the vehicle when the ceiling screen closing signal is triggered; according to the initial screen angle of the vehicle-mounted ceiling screen, the target screen angle stage of the current position of the vehicle-mounted ceiling screen is determined; according to the display mechanism corresponding to the target screen angle stage, the display content of the vehicle-mounted ceiling screen is controlled; according to the anti-pinch mechanism corresponding to the target screen angle stage, the action mode of the vehicle-mounted ceiling screen during the closing process is controlled. Through the present application, the target screen angle stage is determined for the initial screen angle of the vehicle-mounted ceiling screen, and intelligent anti-pinch is implemented according to the display mechanism and anti-pinch mechanism corresponding to the target screen angle stage, thereby improving the safety of the anti-pinch function.

[0029] In this application, the anti-pinch control is performed by the cockpit host, and the sensors and cameras transmit the collected data to the MCU host. The MCU host sends the collected data to the cockpit host and is controlled by the cockpit host. After the cockpit host performs anti-pinch control, the control signal is sent to the MCU host, which is sent by the MCU host to the vehicle-mounted ceiling screen for action.

[0030] See also Figure 1 , Figure 1This is one of the flow charts of the vehicle-mounted ceiling screen control method provided in the embodiment of the present application. Figure 1 As shown in , the vehicle-mounted ceiling screen control method provided by the embodiment of the present application includes:

[0031] S101 . In response to a ceiling screen closing signal, determine an initial screen angle of the vehicle-mounted ceiling screen.

[0032] The initial screen angle is the angle between the vehicle-mounted ceiling screen and the top of the vehicle when the ceiling screen closing signal is triggered.

[0033] The vehicle ceiling screen is set at the first preset position on the top of the vehicle, which is used to provide display content to the rear passengers in the cabin. One side of the vehicle ceiling screen is rotatably connected to the top of the vehicle so that the vehicle ceiling screen can be fixed at the second preset position. Here, the first preset position is the initial installation position of the vehicle ceiling screen, which is used to provide display content to the rear passengers; and the second preset position is another fixed position set by the rotation function of the screen to meet different viewing needs or optimize the viewing experience. This design increases the flexibility and practicality of the vehicle ceiling screen, allowing it to better adapt to different riding environments and passenger needs.

[0034] For example, one side of the vehicle-mounted ceiling screen is not fixed, but is connected to the top of the vehicle. This design allows the vehicle-mounted ceiling screen to be adjusted to different angles relative to the top of the vehicle after receiving instructions to meet the viewing needs of passengers or to fold and close the screen.

[0035] Among them, the ceiling screen closing signal can be triggered by passengers through voice, icons, buttons, etc., that is: the central control screen inside the vehicle, the button at the bottom of the vehicle ceiling screen, and the voice assistant trigger, which is intended to indicate that the vehicle ceiling screen enters the closed state. Once this signal is received, the initial screen angle of the vehicle ceiling screen must be determined first. This angle is the actual angle between the vehicle ceiling screen and the top of the vehicle when the ceiling screen closing signal is triggered. This step provides basic data for the subsequent determination of the movement path and required power of the vehicle ceiling screen.

[0036] In order to accurately obtain the initial screen angle, the vehicle may be equipped with high-precision sensors or cameras to monitor the position and angle of the vehicle-mounted ceiling screen in real time. These devices can quickly capture and process relevant data to ensure that the system can respond to the shutdown signal quickly and accurately.

[0037] After receiving the ceiling screen closing signal transmitted by the MCU host, the cockpit host records the current screen angle θ and turns on the anti-pinch intelligent monitoring.

[0038] S102: Determine a target screen angle stage of a current position of the vehicle-mounted ceiling screen according to an initial screen angle of the vehicle-mounted ceiling screen.

[0039] Here, for the vehicle-mounted ceiling screen, multiple screen angle stages are pre-set, wherein the multiple screen angle stages include the first stage, the second stage and the third stage, the first stage, the second stage and the third stage are all semi-open and semi-closed intervals, the lower limit value of the first stage is the upper limit value of the second stage, and the lower limit value of the second stage is the upper limit value of the third stage.

[0040] There are many types of ceiling screens with structural parts. Taking the maximum opening and closing angle of 110° as an example, when closing at a uniform speed, the overall time required is 7 seconds.

[0041] Specifically, in response to the usage scenarios and functional requirements of the vehicle ceiling screen, we have pre-set multiple screen angle stages, which exist in the form of half-open and half-closed intervals to ensure the continuity and accuracy of the screen angle. These stages include the first stage (90°<θ≤110°), the second stage (45°<θ≤90°) and the third stage (0°<θ≤45°). The upper and lower limits of each stage are connected to each other to form a complete screen angle range. Here, θ is the initial screen angle of the vehicle ceiling screen.

[0042] See also Figure 2 , Figure 2 This is a schematic diagram of the structure of the first stage of the current position of the vehicle-mounted ceiling screen provided in the embodiment of the present application. Figure 2 As shown in , when the initial screen angle exceeds 90° and continues to increase to 110°, taking 110° as an example, it enters the first stage.

[0043] The first stage represents the maximum open state of the screen, which may be used to display videos in full screen or other content that requires a large display area. At this stage, the screen's visible area and interactivity have reached their maximum values. At this stage, the ceiling screen will display the currently playing content. If the user has normal operations on the interface on the car's ceiling screen, the operation is allowed to execute.

[0044] See also Figure 3 , Figure 3 This is a schematic diagram of the structure of the second stage of the current position of the vehicle ceiling screen provided in the embodiment of the present application. Figure 3 As shown in , when the initial screen angle reaches 45° and continues to increase to 90°, taking 90° as an example, it enters the second stage.

[0045] The second stage represents the state where the screen is further opened, which may be used to display more information or perform more complex interactions. At this stage, the user may see more icons, buttons, or text content.

[0046] See also Figure 4 , Figure 4This is a schematic diagram of the structure of the third stage of the current position of the vehicle ceiling screen provided in the embodiment of the present application. Figure 4 As shown in , taking 45° as an example, the initial screen angle range of the third stage is from 0° to 45°.

[0047] This range represents the state from almost completely off to slightly open. At this stage, the screen may only show some basic information or no content at all, depending on the design of the screen and the settings of the system.

[0048] S103: Control the display content of the vehicle-mounted ceiling screen according to the display mechanism corresponding to the target screen angle stage.

[0049] In the first embodiment, there are different display mechanisms for each target screen angle stage.

[0050] The target screen angle stage includes a first stage, wherein the display content corresponding to the vehicle ceiling screen in the first stage is controlled in the following manner:

[0051] When it is detected that the vehicle-mounted ceiling screen is in the first stage, the interface content displayed on the screen when the vehicle-mounted ceiling screen is in the closing process in the first stage continues to be displayed.

[0052] In the first embodiment, the display mechanism of the vehicle ceiling screen is carefully designed to adapt to different screen angle stages, thereby providing a more personalized and optimized user experience. For each target screen angle stage, especially the first stage, the system adopts a specific display control strategy.

[0053] When the car ceiling screen is detected to be in the first stage, that is, the screen opening angle is between 90° and 110°, this stage is generally regarded as the maximum opening state of the screen, suitable for full-screen display content. However, at a certain moment in the first stage, if the system receives a command to close the screen, the car ceiling screen will begin to enter the closing process.

[0054] At this stage, in order to ensure the continuity and smoothness of the user experience, the content on the screen will not be cleared or switched immediately. Instead, it will continue to display the interface content originally displayed on the screen during the closing process of the car ceiling screen, which means that even if the screen is gradually closing, the user can still see the content previously displayed in full screen until the screen is completely closed or reaches the next screen angle stage.

[0055] This display mechanism is designed to take into account the user's visual experience and information acquisition needs during the closing process of the car ceiling screen. It avoids the sudden switching or disappearance of the screen content during the closing process, thereby reducing the user's visual interference and discomfort. At the same time, this also provides users with more time to read or process the information on the screen, especially at the last moment when the screen is about to be completely closed.

[0056] This display mechanism in the first embodiment not only improves the usability and user experience of the vehicle-mounted ceiling screen, but also demonstrates a deep attention to details and user experience. By adopting different display control strategies at different screen angle stages, it can better adapt to user needs and preferences, thereby providing a more personalized and optimized in-vehicle entertainment and information display experience.

[0057] In the second embodiment, the target screen angle stage includes a second stage, wherein the display content corresponding to the vehicle ceiling screen in the second stage is controlled in the following manner:

[0058] When it is detected that the vehicle ceiling screen is in the second stage, a top layer is added and the task stack is stored in the background. The top layer is used to represent the text content displayed on the screen when the vehicle ceiling screen is in the second stage of closing. The task stack is used to represent the objects storing the interface content displayed on the vehicle ceiling screen.

[0059] For example, when the car ceiling screen is in the second stage, the top-level layer TopLayer is added. If the ceiling screen is not the launcher interface at this time, the cockpit host will actively move the task stack to the background, and TopLayer will display a Chinese text prompt that the ceiling screen is being closed.

[0060] Here, when it is detected that the vehicle-mounted ceiling screen is about to enter the second stage (i.e. a specific stage in the closing process), a layer is automatically added to the top of the screen. The main function of this top layer is to display some prompt text content, such as "The ceiling screen is closing, please wait", etc., to inform passengers or drivers of the current screen status changes.

[0061] The task stack is a stack structure used to store the current and previous interface content objects displayed on the vehicle ceiling screen. Each interface content object may contain interface layout information, display data, user interaction status, etc. When the vehicle ceiling screen enters the second stage, all interface content objects in the current task stack are stored in a certain storage area in the background (such as memory, database or file system, etc.) in sequence, so that these interface contents can be restored when needed.

[0062] If the vehicle-mounted ceiling screen triggers the anti-pinch mechanism, the task stack is read from the background storage area, and the interface content is restored on the vehicle-mounted ceiling screen in sequence according to the stack.

[0063] In this step, after the task stack is stored in the background, some resources related to the current screen content (such as images, audio, etc.) can be appropriately released to reduce the burden on memory and processor. At the same time, the stored task stack can also be compressed and optimized to reduce the use of storage space.

[0064] In summary, the display mechanism of the second stage of the vehicle-mounted ceiling screen in the target screen angle stage in the second embodiment realizes the ability to handle the screen closing process and restore the interface content by adding the top layer and task stack storage to the background. This mechanism not only improves the smoothness and continuity of the user experience, but also ensures the effective use of resources and the orderly management.

[0065] In the third embodiment, the target screen angle stage includes a third stage, wherein the display content corresponding to the vehicle ceiling screen in the third stage is controlled in the following manner:

[0066] When it is detected that the vehicle-mounted ceiling screen is in the third stage, the task stack is stored in the background, and the light source behind the vehicle-mounted ceiling screen is turned off, so that the screen of the vehicle-mounted ceiling screen becomes dark until it is black.

[0067] Here, when it is detected that the vehicle ceiling screen has entered the third stage (ie, the last stage before the screen is about to be completely turned off or enters a low-power standby state), the storage operation of the task stack will be immediately triggered.

[0068] The task stack stores objects of the current and previous display interface contents, which may contain layout information, display data, user interaction status, etc. In the third stage, the entire task stack will be serialized and stored in the background persistent storage medium (such as hard disk, flash memory, etc.) to ensure that the previous interface state can be restored when the vehicle ceiling screen is reactivated. In order to improve storage efficiency, a compression algorithm may be used to compress the task stack to reduce the use of storage space. At the same time, the storage process will be optimized to reduce the impact on performance.

[0069] The light source behind the car ceiling screen is usually composed of components such as a backlight module or an LED light strip. In the third stage, the system will send a shutdown command to these light sources to make them gradually turn off or turn off immediately. In order to improve the user experience, a gradient effect may be designed to gradually reduce the screen brightness until it is completely turned off. This can be achieved by adjusting the brightness control signal of the backlight module or the current of the LED light strip. While turning off the light source, other circuit modules related to the screen display (such as drive circuit, signal processing circuit, etc.) will also be turned off to reduce the overall power consumption of the car ceiling screen.

[0070] In the third stage, the screen brightness of the vehicle ceiling screen is gradually reduced until it reaches a black screen state. This can be achieved by adjusting the brightness control parameters of the display driver. When the screen brightness drops to the lowest point, the vehicle ceiling screen will enter a black screen state. At this time, the pixels on the screen will no longer emit light, and the entire screen will appear pitch black. In the black screen state, the vehicle ceiling screen will usually enter a low-power standby mode. At this time, the system only retains the necessary power management and wake-up functions to wait for the user's next operation or wake-up signal.

[0071] In summary, the display mechanism of the third stage of the vehicle-mounted ceiling screen in the target screen angle stage in the third embodiment achieves fine control and low power consumption design of the screen shutoff process by means of task stack storage, light source extinguishing, and screen dimming until the screen turns black. This mechanism not only improves the continuity and smoothness of the user experience, but also ensures the low power consumption and reliability of the vehicle-mounted ceiling screen when it is in the off state.

[0072] S104, controlling the action mode of the vehicle-mounted ceiling screen during the closing process according to the anti-pinch mechanism corresponding to the target screen angle stage.

[0073] Specifically, the anti-pinch mechanism includes a contact anti-pinch mechanism and a non-contact anti-pinch mechanism, wherein the anti-pinch mechanism corresponding to the vehicle-mounted ceiling screen being at the target screen angle stage is controlled in the following manner:

[0074] When it is detected that the vehicle ceiling screen is touched by a preset number of fingers while moving from the current position to the closed position, the contact anti-pinch mechanism is triggered to control the vehicle ceiling screen to stop the closing operation and restore the current screen angle of the vehicle ceiling screen to the initial screen angle;

[0075] Among them, the touch screen sensor of the vehicle-mounted ceiling screen monitors the touch conditions on the screen surface in real time. When a preset number of fingers are detected touching the screen while the screen is moving from the current position to the closed position, the contact anti-pinch mechanism is immediately triggered. Here, the preset number can be 3, 4 or 5, which can be set according to actual needs and is not specifically limited here.

[0076] If the user uses three, four, or five fingers to touch the screen, the cockpit host triggers the anti-pinch mechanism through QNX, stops closing the ceiling screen, and restores the screen to the initial angle.

[0077] Here, QNX is a real-time operating system (RTOS), the full name of which is QNX Neutrino Real-Time Operating System. In the smart cockpit system, QNX can actively trigger the anti-pinch function, stop closing the ceiling screen, and restore it to the previous angle. This is achieved through QNX's real-time, multi-tasking capabilities and modular design. When a potential risk of pinching is detected, QNX can respond quickly and take corresponding preventive measures to ensure the safety of passengers.

[0078] Once the contact anti-pinch mechanism is triggered, a stop signal is immediately sent to the driving mechanism of the vehicle-mounted ceiling screen, causing it to stop the current closing operation and restore the current screen angle of the vehicle-mounted ceiling screen to the initial screen angle (i.e. the angle between the vehicle-mounted ceiling screen and the top of the vehicle when the ceiling screen closing signal is received). This operation can be achieved by adjusting the motion parameters of the driving mechanism to ensure that the screen returns to its initial position smoothly and quickly.

[0079] For example, after the contact anti-pinch mechanism is triggered, the user may be prompted by sound, light or screen display to inform them that the screen has stopped closing and returned to its initial position. The vehicle-mounted ceiling screen can also be reopened by touching the preset number of fingers as mentioned above. If no operation is performed after the anti-pinch mechanism is triggered, the cockpit host will continue to perform the closing operation after a preset time period after detecting that there are no foreign objects on the closing trajectory. Preferably, the preset time period can be 3 seconds.

[0080] When the controller and / or sensor detects that there is a foreign object on the moving track of the vehicle-mounted ceiling screen when it moves from the current position to the closed position, the non-contact anti-pinch mechanism is triggered to control the vehicle-mounted ceiling screen to stop the closing operation.

[0081] In an optional embodiment, a controller and / or sensors (such as infrared sensors, ultrasonic sensors, etc.) are used to monitor in real time whether there are foreign objects on the moving trajectory of the vehicle-mounted ceiling screen when it moves from the current position to the closed position. These sensors can be installed around or inside the screen to cover the entire moving trajectory.

[0082] When the controller and / or sensor detects the presence of foreign objects on the moving track, the non-contact anti-pinch mechanism is immediately triggered, and a stop signal is sent to the driving mechanism of the vehicle-mounted ceiling screen to stop the closing operation.

[0083] To ensure safety, a safety distance threshold may be set. When the distance between the foreign object detected by the sensor and the screen is less than this threshold, the non-contact anti-pinch mechanism will be triggered. This can avoid frequent screen shutdown operations due to false alarms, affecting the user experience.

[0084] After the non-contact anti-pinch mechanism is triggered, the corresponding exception handling logic needs to be designed. For example, if the foreign object is removed but the screen still cannot continue to close (perhaps due to other faults), it may be necessary to send a warning signal to the user or enter a fault handling mode.

[0085] When both contact and non-contact anti-pinch mechanisms are configured, their priorities need to be set. Generally speaking, the contact anti-pinch mechanism has a higher priority because it directly reflects the user's direct intervention, continuously monitors the status changes of the vehicle-mounted ceiling screen, and provides feedback to the user or other parts of the system when necessary, including screen position, anti-pinch mechanism status, abnormal information, etc.

[0086] If there is foreign object or external force triggering the ceiling screen anti-pinch system, the ceiling screen will stop closing. After the cockpit host detects through the in-car camera and sensor that there is no foreign object on the ceiling screen closing trajectory, it will automatically execute the ceiling screen closing logic.

[0087] Preferably, when it is detected that a hand is pressed or stuck between the vehicle-mounted ceiling screen and the top of the vehicle, the current will change. After the hardware carried by the structural component itself detects the change in current, the mechanical structure will stop and close directly without transmitting a signal to the MCU host, thereby ensuring the safety of passengers.

[0088] In summary, through contact and non-contact anti-pinch mechanisms, the risk of pinching can be effectively avoided during the closing process of the vehicle-mounted ceiling screen, while improving the user experience and system safety. These measures not only help protect the user's physical health, but also enhance the user's trust and satisfaction with the vehicle-mounted ceiling screen.

[0089] Specifically, after detecting that the current screen angle of the vehicle-mounted ceiling screen reaches a preset angle, the structural components of the vehicle-mounted ceiling screen are controlled to be locked, and the task stack stored in the background is cleared.

[0090] After the screen reaches 0 degrees, the structural parts are automatically locked. After the smart cockpit detects that the ceiling screen is closed, it will stop refreshing the surfaceflinger of the ceiling screen display to reduce performance overhead.

[0091] Among them, during the closing process of the vehicle-mounted ceiling screen, the current screen angle of the screen is monitored in real time. When it is detected that the current angle of the screen reaches the preset locking angle (such as 0° close to full closure), the locking mechanism is triggered.

[0092] Once the locking mechanism is triggered, a locking command is sent to the structural parts of the vehicle-mounted ceiling screen (such as locks, brackets, etc.). After receiving the command, the structural parts will execute the locking action to ensure that the screen is firmly fixed in the closed position to prevent the screen from accidentally opening due to vibration or external force.

[0093] When the car-mounted ceiling screen is fully closed, that is, the screen angle reaches 0 degrees, the structural parts will automatically lock to ensure that the screen is in a fully closed and stable state, enhancing the reliability and safety of the screen closing.

[0094] When the structure is locked, the task stack previously stored in the background is cleared. The task stack may contain information such as the display content before the screen is turned off and the user interaction status. The task stack is cleared to release system resources and avoid unnecessary memory usage. Before clearing the task stack, check whether there are any unfinished important tasks or user operations that need to be saved to ensure data integrity and security.

[0095] In addition, the cockpit host continuously monitors the status of the vehicle's ceiling screen, including whether it has been closed and whether it is in a stable state. Once it detects that the ceiling screen has been closed and the structural parts have been locked, the smart cockpit system will stop refreshing the surfaceflinger of the ceiling screen display. Surfaceflinger is the component responsible for graphics synthesis and display in the Android system. Stopping its refresh can reduce the load on the CPU and GPU, thereby reducing the system's performance overhead and power consumption. Through this optimization measure, the cockpit host can improve the overall performance and energy efficiency of the system while ensuring user experience.

[0096] Preferably, the angle monitoring and control process during the closing process of the vehicle-mounted ceiling screen is as follows:

[0097] See also Figure 5 , Figure 5 This is a second flow chart of the vehicle-mounted ceiling screen control method provided in the embodiment of the present application. Figure 5 As shown in , the vehicle-mounted ceiling screen control method provided by the embodiment of the present application includes:

[0098] S201, when the vehicle-mounted ceiling screen moves from the current position to the closed position, monitoring the current screen angle of the vehicle-mounted ceiling screen during the movement;

[0099] Here, in the process of the vehicle-mounted ceiling screen moving from the current position to the closed position, the current angle of the screen is monitored in real time to ensure that it is closed smoothly according to the predetermined trajectory and speed, and the angle change of the screen is monitored by angle sensors (such as gyroscopes, rotary encoders, etc.) or image recognition technology. These sensors or technologies can provide high-precision angle data to help the system accurately judge the position and status of the screen, and record the monitored current screen angle data in real time to facilitate subsequent judgment and control of angle switching.

[0100] S202, determining whether the current screen angle and the initial screen angle are in the same screen angle stage;

[0101] Here, the difference between the current screen angle and the initial screen angle (i.e., the angle when the screen starts to close) is compared to determine whether an angle switch is required for the convenience of management and control. If the current screen angle and the initial screen angle are both in the same screen angle stage, it means that the screen did not cross to a new angle stage during the closing process, so no angle switch is required. On the contrary, if the two are not in the same stage, corresponding control is required based on the display mechanism and anti-pinch mechanism after the angle switch.

[0102] S203: If it is detected that the current screen angle and the initial screen angle are both in the same screen angle stage, no angle switching is performed, and control is continued according to the display mechanism and the anti-pinch mechanism corresponding to the target screen angle stage in which the initial screen angle is located;

[0103] In this case, continue to control the closing operation of the vehicle-mounted ceiling screen according to the current closing speed and trajectory until the screen is completely closed or reaches the next predetermined angle stage. Although the angle is not switched, it is still necessary to continuously monitor the safety status of the screen closing process, such as whether there are foreign objects obstructing, whether the user's stop command is received, etc.

[0104] S204. If it is detected that the current screen angle and the initial screen angle are not at the same screen angle stage, the angle is switched, and the vehicle-mounted ceiling screen is controlled according to the display mechanism and anti-pinch mechanism after the angle switching, and the initial screen angle is greater than the current screen angle.

[0105] Here, before switching the angle, some preparation work needs to be done, such as adjusting the motion parameters of the driving mechanism, updating the display content, etc. According to the new screen angle stage, the display content, brightness, contrast and other parameters of the vehicle-mounted ceiling screen need to be adjusted to ensure that users can get a good visual experience at different angles. During the angle switching process, special attention should be paid to the operation of the anti-pinch mechanism. If the screen may contact the user or an obstacle during the switching process, the closing operation should be stopped immediately and corresponding safety measures should be taken.

[0106] In this step, it is pointed out that the initial screen angle is greater than the current screen angle, which means that the screen is moving from the open state to the closed state. The control strategy needs to be adjusted according to this change to ensure that the screen is closed smoothly and safely.

[0107] In summary, through the monitoring and control process, the current screen angle can be accurately judged and corresponding control strategies can be adopted during the closing process of the vehicle-mounted ceiling screen, thereby ensuring the safety of the user and the stable operation of the system.

[0108] The vehicle-mounted ceiling screen control method and vehicle provided in the embodiments of the present application determine the initial screen angle of the vehicle-mounted ceiling screen in response to the ceiling screen closing signal, where the initial screen angle is the angle between the vehicle-mounted ceiling screen and the top of the vehicle when the ceiling screen closing signal is triggered; determine the target screen angle stage where the current position of the vehicle-mounted ceiling screen is located according to the initial screen angle of the vehicle-mounted ceiling screen; control the display content of the vehicle-mounted ceiling screen according to the display mechanism corresponding to the target screen angle stage; and control the action mode of the vehicle-mounted ceiling screen during the closing process according to the anti-pinch mechanism corresponding to the target screen angle stage. The present application determines the target screen angle stage for the initial screen angle of the vehicle-mounted ceiling screen, and implements intelligent anti-pinch according to the display mechanism and anti-pinch mechanism corresponding to the target screen angle stage, thereby improving the safety of the anti-pinch function.

It can intelligently monitor anti-pinch and greatly improve the diversity and experience of the anti-pinch function. It is safer and more comfortable. The screen status and anti-pinch status of the ceiling screen are determined through user instructions and intelligent monitoring. While simple operation, it can also better present the content of the ceiling screen at different angles.

[0110] The cockpit host of the present application executes the intelligent monitoring program for anti-pinch of the ceiling screen, controls the layer display of the vehicle-mounted ceiling screen and controls the anti-pinch execution status at each screen angle stage. The cockpit host processes the External peripheral screen display of the vehicle-mounted ceiling screen, and the camera, sensor and vehicle-mounted ceiling screen signal transmission is realized between the cockpit host and the MCU host. The cockpit host drives the MCU host to perform anti-pinch operations on the ceiling screen. The vehicle-mounted ceiling screen transmits the signal that the screen on the vehicle-mounted ceiling screen is triggered to the MCU host, receives the electrical signal processed by the MCU host, and takes action according to the electrical signal.

[0112] The MCU host 602 determines the initial screen angle of the vehicle-mounted ceiling screen 603 in response to the ceiling screen closing signal, and the initial screen angle is the angle between the vehicle-mounted ceiling screen 603 and the top of the vehicle when the ceiling screen closing signal is triggered;

[0113] The cockpit host 601 determines the target screen angle stage of the current position of the vehicle-mounted ceiling screen 603 according to the initial screen angle of the vehicle-mounted ceiling screen 603;

[0114] The cockpit host 601 controls the display content of the vehicle-mounted ceiling screen 603 according to the display mechanism corresponding to the target screen angle stage;

[0115] The cockpit host 601 controls the action mode of the vehicle-mounted ceiling screen 603 during the closing process according to the anti-pinch mechanism corresponding to the target screen angle stage.
