[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. The figure numbers in the present application are only used to distinguish various steps in the solutions, and are not used to limit the execution order of the various steps, and the specific execution order is subject to the description in the specification.

[0031] The vehicle roof-mounted screen is a screen hung in a fixed position in the middle of the roof of a vehicle, providing value-added services for users to meet the diversified needs of different users.

[0032] The interaction between the vehicle and the user terminal device is also an essential function of the vehicle, and becomes increasingly important and rich. Users can communicate with the vehicle roof-mounted screen through the terminal device, for example, projecting the screen interface of the terminal device onto the vehicle roof-mounted screen to play.

[0033] In recent years, the Near Field Communication (NFC) touch function has been widely used in various screens or terminal devices such as mobile phones, and information flow can be realized by only NFC touch. Although the NFC function is convenient for information interaction, the vehicle roof-mounted screen is currently hung in a fixed position on the roof and is relatively high and far away, so it is not convenient for users to realize the NFC function, especially for users in different positions in the vehicle.

[0034] How to facilitate users to use the NFC function of the vehicle roof-mounted screen and simplify the cumbersome steps of user operation of the vehicle roof-mounted screen is a technical problem to be solved at present.

[0035] To solve the problems in the prior art, the application provides a vehicle-mounted ceiling screen control scheme. In view of the problem that the user's operation of the vehicle-mounted ceiling screen is complicated, the near field communication function of the vehicle-mounted ceiling screen and the near field communication function of the user terminal device are combined to control the vehicle-mounted ceiling screen to interact with the user terminal device. Specifically, first, in response to a target request operation of the user, the position of the user terminal device is detected, and the target request operation is used to request to turn on the near field communication function of the vehicle-mounted ceiling screen. Then, based on the detected position of the terminal device, the vehicle-mounted ceiling screen is controlled to move towards the direction close to the terminal device, so that the terminal device and the vehicle-mounted ceiling screen perform near field communication. In this way, based on the request of the user, the near field communication function of the vehicle-mounted ceiling screen can be turned on to realize connection with the user terminal device. The near field communication distance range is small, and the stability of the connection can be ensured when reaching the near field communication distance range, and the signal is not easy to interrupt. Moreover, the position of the terminal device used by the user to perform near field communication with the vehicle-mounted ceiling screen is automatically identified, and the vehicle-mounted ceiling screen is controlled to move close to the terminal device, so that the automatic adaptive and rapid response of "screen finding terminal device" is realized. The distance between the vehicle-mounted ceiling screen and the user terminal device can quickly and accurately reach the near field communication distance range, the near field communication demand is met, the need for manual intervention of the user is reduced, the convenience and efficiency of the user using the near field communication function of the vehicle-mounted ceiling screen are significantly improved, the use experience of the near field communication function is improved, the intelligentization and man-machine interaction friendliness of the in-vehicle interaction are enhanced, and the multifunctionality and comfort of the vehicle are ensured.

[0036] Specifically, the vehicle-mounted ceiling screen control scheme embodiment of the application includes a vehicle-mounted ceiling screen control method and a vehicle and a readable storage medium, and each embodiment will be described in detail below.

[0037] One embodiment of the application provides a vehicle-mounted ceiling screen control method applied to a vehicle controller, Figure 1 FIG. 1 is a flowchart of a vehicle-mounted ceiling screen control method according to an embodiment of the application.

[0038] As shown in FIG. 1, the method of this embodiment includes the following steps S102 to S104. Figure 1

[0039] Step S102, in response to a target request operation of the user, the position of the user terminal device is detected, and the target request operation is used to request to turn on the near field communication function of the vehicle-mounted ceiling screen.

[0040] The vehicle controller executing the method can process various requests of the user, and the user can be any user in the corresponding vehicle. For the application scenario of the vehicle-mounted ceiling screen control, the user is usually a passenger in the back row of the vehicle. The vehicle-mounted ceiling screen is hung in the middle fixed position of the roof of the vehicle to provide value-added services for the corresponding user and meet the diversified needs of different users. ​

[0041] The user sends a target request operation for requesting to open the near field communication function of the vehicle roof screen, and the vehicle controller triggers detection of the position of the user terminal device after receiving the target request operation.

[0042] According to the scheme provided in the above embodiment, in step S102, the position of the user terminal device is detected in response to the target request operation of the user, including: in response to the target request operation initiated by the user through voice, the posture of the user is recognized through the image collected by the vehicle camera; and when the posture of the user holding an object is recognized, the position of the terminal device is determined.

[0043] In this embodiment, the user actively proposes to open the near field communication function of the vehicle roof screen through voice, for example, NFC touch-on-touch demand. The vehicle controller monitors the requests of each user in the vehicle, collects the voice instructions issued by each user through the vehicle sound sensor, for example, a microphone, and detects the target request operation of the user for triggering the near field communication function of the vehicle roof screen through voice recognition.

[0044] For example, the vehicle controller can include a voice recognition unit for recognizing the target request operation output by the user voice, and serving as a prerequisite for starting to control the roof screen.

[0045] The user provides the target request operation for requesting to open the near field communication function of the vehicle roof screen through voice, which is more convenient than manual request of the user, and the demand of the user is discovered in time through voice recognition, improving the timeliness of system response. The voice recognition triggers the accurate start of the near field communication function of the vehicle roof screen through accurate recognition of the user's instruction, reduces misoperation, improves the efficiency of system response, and thus improves the convenience of user operation.

[0046] After receiving the target request operation of the user, detection of the position of the user terminal device is started. The user requests to open the near field communication function of the vehicle roof screen, which means that the user needs to perform corresponding near field communication between his terminal device and the vehicle roof screen. The near field communication requires close contact between the terminal device and the vehicle roof screen, so the terminal device of the user needs to be exposed in the vehicle space, for example, the user holds the terminal device and holds it up to a certain height. At this time, the position of the user terminal device needs to be detected first.

[0047] In this embodiment, the corresponding image can be collected through the vehicle camera of the vehicle, for example, the in-vehicle camera, and the posture of the user is recognized through the image recognition unit of the vehicle controller to determine whether the terminal device has been held up by the user. The user has various postures, and if the posture of the user holding or holding up an object is recognized, the position of the terminal device is determined based on the position of the corresponding object.

[0048] When the user outputs a request to open the near field communication function of the vehicle ceiling suction screen through voice, the position of the user can be determined in combination with the monitored pickup area, and the position of the terminal device of the user can be detected in combination with the recognized posture of the user in the pickup area.

[0049] In step S104, based on the detected position of the terminal device, the vehicle ceiling suction screen is controlled to move towards the direction close to the terminal device, so that the terminal device and the vehicle ceiling suction screen perform near field communication.

[0050] The position of the user's handheld terminal device detected in real time is a three-dimensional space position, including corresponding x-axis coordinates, y-axis coordinates and z-axis coordinates. Taking the driving direction of the vehicle as a reference, the y-axis corresponds to the front-rear direction of the vehicle driving, the x-axis corresponds to the left-right direction of the vehicle driving, and the z-axis corresponds to the up-down direction of the vehicle driving.

[0051] If the position of the user's terminal device is detected, the vehicle ceiling suction screen can be controlled to move towards the direction close to the position of the terminal device to perform near field communication close to the terminal device. The distance between the vehicle ceiling suction screen and the terminal device is controlled to meet the user's near field communication requirements, such as being within the near field communication distance range of the near field communication function.

[0052] Based on the above-mentioned embodiments, in one specific embodiment, optionally, in step S104, the vehicle ceiling suction screen can move along a target direction, the target direction including at least one of a first direction, a second direction and a third direction, the first direction corresponding to the front-rear direction of the vehicle driving, the second direction corresponding to the left-right direction of the vehicle driving, and the third direction corresponding to the up-down direction of the vehicle driving; based on the detected position of the terminal device, the vehicle ceiling suction screen is controlled to move towards the direction close to the terminal device, including: based on the position of the terminal device and the position of the vehicle ceiling suction screen, determining the distance between the vehicle ceiling suction screen and the terminal device, the distance including a first distance along the first direction, a second distance along the second direction and a third distance along the third direction; based on the distance and the corresponding near field communication distance range of the near field communication function, the vehicle ceiling suction screen is controlled to move close to the terminal device along the target direction.

[0053] In this embodiment, the vehicle ceiling suction screen can move along at least one of the first direction, the second direction and the third direction. Here, the first direction includes forward movement and backward movement, the second direction includes left movement and right movement, and the third direction includes upward movement and downward movement.

[0054] In one embodiment, if the vehicle ceiling screen is movable in a first direction (also referred to as a front-rear direction), based on the detected position of the terminal device, when the vehicle ceiling screen is controlled to move towards the terminal device, first, based on the position of the terminal device and the position of the vehicle ceiling screen, the distance between the terminal device and the vehicle ceiling screen is determined. If the first distance in the first direction exceeds the near field communication distance range, the vehicle ceiling screen is controlled to move towards the terminal device in the first direction based on the first distance until the first distance is within the near field communication distance range.

[0055] Similarly, for embodiments in which the vehicle ceiling screen is movable in a second direction (also referred to as a left-right direction) and / or a third direction (also referred to as an up-down direction), the steps described above for movement in the first direction can be referred to. Ultimately, the vehicle ceiling screen is caused to move towards the terminal device in the corresponding direction until the distance between the terminal device and the vehicle ceiling screen is within the near field communication distance range.

[0056] By determining the direction in which the vehicle ceiling screen should move towards the terminal device based on the distance between the vehicle ceiling screen and the terminal device, and controlling the vehicle ceiling screen to move towards the terminal device in the corresponding direction, the vehicle ceiling screen can be quickly and accurately moved to a distance within which near field communication with the terminal device can be achieved, thereby improving the efficiency of near field communication between the two.

[0057] Further, when the vehicle ceiling screen is controlled to move towards the terminal device in the target direction, if the distance by which the vehicle ceiling screen moves in the corresponding direction reaches the preset maximum distance in the corresponding direction, but the distance between the vehicle ceiling screen and the terminal device is still not within the near field communication distance range.

[0058] In one embodiment, the method further comprises: based on the distance and the near field communication distance range corresponding to the near field communication function, controlling the seat on which the user is seated to move towards the vehicle ceiling screen in the target direction, so that the terminal device moves towards the vehicle ceiling screen in the target direction.

[0059] In this embodiment, if the target distance between the vehicle ceiling screen and the terminal device exceeds the near field communication distance range after the vehicle ceiling screen has moved in the corresponding direction by the preset maximum distance, the target distance including at least one of the first distance, the second distance, and the third distance, the seat on which the user is seated is controlled to move relative to the vehicle ceiling screen in the corresponding direction based on the target distance until the corresponding distance is within the near field communication distance range.

[0060] After detecting the position of the user terminal device through step S102, the distance between the position of the terminal device and the position of the vehicle ceiling suction screen corresponding to the three-dimensional space, i.e., the first distance corresponding to the first direction, the second distance corresponding to the second direction, and the third distance corresponding to the third direction between the two, can be determined based on the position of the terminal device and the position of the vehicle ceiling suction screen.

[0061] In this embodiment, after the user requests to turn on the near field communication function of the vehicle ceiling suction screen, in order to ensure that the terminal device and the vehicle ceiling suction screen can successfully perform near field communication, it is necessary to ensure that the distance between the position of the terminal device and the position of the vehicle ceiling suction screen corresponding to the three-dimensional space meets the near field communication requirement, i.e., the near field communication distance required for normal near field communication.

[0062] Generally, the near field communication distance range is, for example, between 0-10 centimeters, and 10 centimeters is the maximum distance of the near field communication distance range. If the maximum distance is exceeded, near field communication between two devices with near field communication function cannot be realized. Therefore, the distance between the terminal device and the vehicle ceiling suction screen should be within the near field communication distance range, i.e., near field communication can be successfully realized.

[0063] Since the user's terminal device and the vehicle ceiling suction screen can be in different horizontal planes or vertical planes, the three-dimensional straight-line distance between the two should be at least less than or equal to 10 centimeters. Based on the near field communication distance range, under the assumption that the position of the user's terminal device is unchanged, it can be determined that under the premise that the user's terminal device and the vehicle ceiling suction screen can normally perform near field communication, the distances corresponding to the first direction, the second direction, and the third direction between the two are within the corresponding near field communication distance range. When the distances in the three directions are within the corresponding near field communication distance range, the three-dimensional straight-line distance between the terminal device and the vehicle ceiling suction screen is at least less than or equal to 10 centimeters.

[0064] In this embodiment, the vehicle ceiling suction screen can move corresponding to the target direction. If the distance between the current position of the vehicle ceiling suction screen and the current position of the terminal device corresponding to the target direction exceeds the corresponding near field communication distance range, the vehicle ceiling suction screen needs to be controlled to move to a position that meets the near field communication requirement along the target direction.

[0065] Correspondingly, if the distance between the current position of the vehicle ceiling suction screen and the current position of the terminal device corresponding to the target direction is within the corresponding near field communication distance range, i.e., the current position of the vehicle ceiling suction screen meets the near field communication requirement, the vehicle ceiling suction screen does not need to be controlled to move to the terminal device along the target direction.

[0066] In other embodiments, in order to improve the success rate of near field communication between the vehicle ceiling suction screen and the terminal device, the closer the distance between the two, the relatively higher the success rate, the current position of the vehicle ceiling suction screen can also be controlled to move correspondingly to shorten the near field communication distance between the two.

[0067] In the premise that the first distance between the vehicle-mounted ceiling screen and the terminal device meets the near field communication requirement by moving the vehicle-mounted ceiling screen along the first direction to approach the terminal device, it is further needed to judge whether the second distance and the third distance between the vehicle-mounted ceiling screen and the terminal device meet the corresponding near field communication requirement, i.e. whether the comprehensive three-dimensional distance between the vehicle-mounted ceiling screen and the terminal device meets the near field communication requirement of the farthest 10 centimeters.

[0068] If the first distance does not meet the near field communication distance range corresponding to the near field communication requirement, and the second distance and the third distance both meet the near field communication distance range corresponding to the near field communication requirement, then by moving the vehicle-mounted ceiling screen to the appropriate position only through the front and back movement, the near field communication between the vehicle-mounted ceiling screen and the terminal device can be successfully realized.

[0069] If the first distance does not meet the near field communication distance range corresponding to the near field communication requirement, and the second distance and the third distance also do not meet the near field communication distance range corresponding to the near field communication requirement, then by moving the vehicle-mounted ceiling screen to the appropriate position through the left and right movement and the up and down movement, the near field communication between the vehicle-mounted ceiling screen and the terminal device can be successfully realized.

[0070] If the vehicle-mounted ceiling screen moves to the corresponding preset maximum distance along the target direction, there is still a distance between the vehicle-mounted ceiling screen and the terminal device that does not meet the near field communication distance range corresponding to the near field communication requirement. At this time, the seat on which the user sits can be further controlled in linkage to move along the target direction to the vehicle-mounted ceiling screen based on the current distance between the vehicle-mounted ceiling screen and the terminal device, until the corresponding distance is located within the near field communication distance range that meets the corresponding near field communication requirement.

[0071] The seat supports moving adjustment along the front and back direction, the up and down direction and the left and right direction, whereby according to the first distance between the terminal device and the vehicle-mounted ceiling screen along the front and back direction, it is judged whether the seat needs to be controlled in linkage to be raised or lowered to realize the adjustment of the first distance to meet the corresponding near field communication requirement. Similarly, according to the second distance between the terminal device and the vehicle-mounted ceiling screen along the up and down direction, it is judged whether the seat needs to be controlled in linkage to be raised or lowered to realize the adjustment of the second distance to meet the corresponding near field communication requirement. Similarly, according to the third distance between the terminal device and the vehicle-mounted ceiling screen along the left and right direction, it is judged whether the seat needs to be controlled in linkage to be moved left or right to realize the adjustment of the third distance to meet the corresponding near field communication requirement. Until the corresponding distances between the terminal device and the vehicle-mounted ceiling screen after adjustment are all located within the near field communication distance range corresponding to the near field communication requirement.

[0072] In this embodiment, according to the detection result of the terminal device position, in combination with the current position of the vehicle-mounted ceiling screen and the current position of the seat occupied by the user, the vehicle-mounted ceiling screen can be automatically controlled to move in the front-rear direction in the roof space, and the seat can be automatically controlled to move in the front-rear direction, the left-right direction and / or the up-down direction, so that the corresponding distance between the position of the terminal device and the position of the vehicle-mounted ceiling screen after moving meets the near field communication requirement.

[0073] Here, the seat can automatically move forward and backward, raise, lower or move left and right according to the front-rear distance, up-down distance and left-right distance between the vehicle-mounted ceiling screen and the terminal device, to assist in meeting the position requirement of the near field communication touch function between the vehicle-mounted ceiling screen and the terminal device.

[0074] If the position of the user's terminal device changes with the user's hand holding, the position of the user's terminal device can be monitored in real time during the process of controlling the vehicle-mounted ceiling screen to approach the terminal device, and the distance between the vehicle-mounted ceiling screen and the terminal device can be adjusted in real time. And according to the adjusted distance, the vehicle-mounted ceiling screen is controlled to approach the terminal device until the near field communication requirement is met, or according to the adjusted distance, the vehicle-mounted ceiling screen is controlled to approach the terminal device, and the user seat is controlled to move relative to the vehicle-mounted ceiling screen until the near field communication requirement is met.

[0075] By monitoring the three-dimensional space position of the user's hand-held terminal device in real time, the vehicle-mounted ceiling screen can adaptively move according to the real-time position of the terminal device, so as to accurately match the target distance that meets the near field communication requirement. In addition, the seat linkage can effectively compensate for the differences in front-rear longitudinal position, up-down height position and left-right lateral position caused by different user heights and hand-held terminal devices, realize coordinated adjustment in the front-rear, up-down and left-right directions, and ensure effective reach of the near field communication function. The linked seat solves the problem of insufficient space adjustment caused by the limited movement of the vehicle-mounted ceiling screen in the front-rear, up-down and left-right directions, makes up for the defect that the movable ceiling screen can only move a preset maximum distance, optimizes the distance required for the near field communication touch function in the three-dimensional space, and finally enhances the success rate of the near field communication touch function between the terminal device and the vehicle-mounted ceiling screen.

[0076] In addition, when the maximum amplitude of the seat adjustment cannot meet the requirements in the front-rear, up-down and / or left-right directions, the user can be prompted to manually adjust the position of the terminal device. By sending a prompt to manually adjust the position of the terminal device, as a supplementary solution when the seat linkage distance is insufficient, the user is guided to actively cooperate with the adjustment, further improving the success rate of the near field communication operation and improving the system compatibility and fault tolerance.

[0077] The purpose is to minimize manual intervention by the user, and only need to manually take out the terminal device, the vehicle-mounted ceiling screen can be automatically approached to the terminal device and the NFC touch function can be automatically realized.

[0078] Therefore, by the combination and coordinated control of the movement of the vehicle roof suction screen along the target direction, the movement of the user seat along the target direction, and the manual movement of the terminal device, a quick, convenient, and comfortable NFC touch experience in the vehicle is ultimately achieved.

[0079] In one embodiment, the application is described based on the detected position of the terminal device, and the vehicle roof suction screen is controlled to move close to the terminal device in the front-rear direction, the left-right direction, and the up-down direction.

[0080] Specifically, the distance between the vehicle roof suction screen and the terminal device is determined based on the position of the terminal device and the position of the vehicle roof suction screen. If the target distance among the first distance, the second distance, and the third distance exceeds the near field communication distance range, the vehicle roof suction screen is controlled to move towards the terminal device along the corresponding direction based on the target distance until the target distance is within the near field communication distance range.

[0081] In this embodiment, the x-axis coordinate, the y-axis coordinate, and the z-axis coordinate of the vehicle roof suction screen can be changed in the three-dimensional space, i.e., the vehicle roof suction screen can move in the front-rear direction, the up-down direction, and the left-right direction within a certain range of the roof space. The vehicle roof suction screen can move in the front, rear, left, right, up, and down directions within the roof space based on the slide rails arranged in the front-rear direction, the slide rails arranged in the up-down direction, and the slide rails arranged in the front-rear and left-right directions.

[0082] After detecting the position of the user terminal device through step S102, the distance between the position of the terminal device and the position of the vehicle roof suction screen in the corresponding three-dimensional space can be first determined based on the position of the terminal device and the position of the vehicle roof suction screen, i.e., the first distance in the front-rear direction, the second distance in the left-right direction, and the third distance in the up-down direction.

[0083] In this embodiment, after the user requests to turn on the near field communication function of the vehicle roof suction screen, to ensure that the terminal device and the vehicle roof suction screen can smoothly perform near field communication, the distance between the position of the terminal device and the position of the vehicle roof suction screen in the corresponding three-dimensional space needs to meet the near field communication requirement, i.e., the near field communication distance required for normal near field communication.

[0084] If the first distance corresponding to the current position of the vehicle roof suction screen and the current position of the terminal device exceeds the corresponding near field communication distance range, the vehicle roof suction screen needs to be controlled to move in the front-rear direction to a position that meets the near field communication requirement. Specifically, as long as the first distance does not meet the near field communication requirement, the vehicle roof suction screen needs to be controlled to move towards the terminal device in the front-rear direction, so that the first distance falls within the corresponding near field communication distance range, regardless of whether the terminal device is in front of or behind the vehicle roof suction screen.

[0085] Correspondingly, if the first distance calculated according to the current position of the vehicle-mounted ceiling screen and the current position of the terminal device is located in the corresponding near field communication distance range, that is, the current position of the vehicle-mounted ceiling screen meets the near field communication requirement, the vehicle-mounted ceiling screen does not need to be controlled to move towards the terminal device in the front-rear direction.

[0086] Under the premise that the vehicle-mounted ceiling screen is moved to approach the terminal device in the front-rear direction, so that the first distance between the vehicle-mounted ceiling screen and the terminal device meets the near field communication requirement, it is further needed to judge whether the second distance and the third distance between the vehicle-mounted ceiling screen and the terminal device meet the corresponding near field communication requirement. If the second distance calculated according to the current position of the vehicle-mounted ceiling screen and the current position of the terminal device exceeds the corresponding near field communication distance range, the vehicle-mounted ceiling screen needs to be controlled to move towards the position meeting the near field communication requirement in the left-right direction. Specifically, as long as the second distance does not meet the near field communication requirement, the vehicle-mounted ceiling screen needs to be controlled to approach the terminal device in the left-right direction, so that the second distance falls within the corresponding near field communication distance range, regardless of whether the terminal device is on the left side or the right side of the vehicle-mounted ceiling screen.

[0087] Correspondingly, if the second distance calculated according to the current position of the vehicle-mounted ceiling screen and the current position of the terminal device is located in the corresponding near field communication distance range, that is, the current position of the vehicle-mounted ceiling screen meets the near field communication requirement, the vehicle-mounted ceiling screen does not need to be controlled to move towards the terminal device in the left-right direction.

[0088] Under the premise that the vehicle-mounted ceiling screen is moved to approach the terminal device in the front-rear direction, so that the first distance and the third distance between the vehicle-mounted ceiling screen and the terminal device meet the near field communication requirement, it is further needed to judge whether the third distance between the vehicle-mounted ceiling screen and the terminal device meets the corresponding near field communication requirement. If the third distance calculated according to the current position of the vehicle-mounted ceiling screen and the current position of the terminal device exceeds the corresponding near field communication distance range, the vehicle-mounted ceiling screen needs to be controlled to move towards the position meeting the near field communication requirement in the up-down direction. The terminal device is below the vehicle-mounted ceiling screen, the third distance does not meet the near field communication requirement, and the vehicle-mounted ceiling screen needs to be controlled to approach the terminal device in the downward direction, so that the third distance falls within the corresponding near field communication distance range.

[0089] Correspondingly, if the third distance calculated according to the current position of the vehicle-mounted ceiling screen and the current position of the terminal device is located in the corresponding near field communication distance range, that is, the current position of the vehicle-mounted ceiling screen meets the near field communication requirement, the vehicle-mounted ceiling screen does not need to be controlled to move towards the terminal device in the downward direction.

[0090] It should be noted that the order of judging the first distance, the second distance and the third distance described above can be any order, as long as the adjustment meets the near field communication requirement.

[0091] In this embodiment, the vehicle-mounted ceiling screen can have front-back, up-down and left-right moving functions. The vehicle-mounted ceiling screen can complete the movement in the front-back, left-right and up-down directions, further simplifying the system linkage complexity, realizing more comprehensive space self-adaptation, and improving the overall intelligent level and operation autonomy of the system.

[0092] Further, to avoid the risk of collision between the vehicle-mounted ceiling screen and the terminal device during the process of the vehicle-mounted ceiling screen approaching the terminal device, optionally, the distance between the vehicle-mounted ceiling screen and the terminal device when they perform near field communication is the maximum distance in the near field communication distance range.

[0093] The near field communication distance meeting the near field communication requirement is usually within the range of 0-10 cm, and the maximum near field communication distance is 10 cm. The maximum near field communication distance is the farthest distance between the terminal device and the vehicle-mounted ceiling screen that can be recognized by each other. The maximum distance beyond this range cannot normally perform near field communication. The distance within this range can perform near field communication, but the range of 10 cm is relatively small. Therefore, after detecting the position of the user terminal device, the distance between the vehicle-mounted ceiling screen and the terminal device can be set to the maximum value of the near field communication distance range, for example, 10 cm. When the vehicle-mounted ceiling screen moves to a position with a distance of 10 cm from the terminal device, the vehicle-mounted ceiling screen is controlled to stop moving.

[0094] The maximum distance can be regarded as the maximum safety distance to avoid collision between the vehicle-mounted ceiling screen and the terminal device. The maximum safety distance setting is a safety constraint for controlling the movement of the vehicle-mounted ceiling screen. By setting the maximum safety distance, the problem of preventing physical collision between the vehicle-mounted ceiling screen and the terminal device can be solved, safe operation is realized, and the safety of the vehicle-mounted ceiling screen and the terminal device and the user's terminal device is ensured. The vehicle-mounted ceiling screen can be controlled to adaptively move according to the real-time position of the terminal device, so as to accurately match the maximum safety distance of NFC and avoid the risk of collision caused by position deviation.

[0095] Therefore, by setting the distance between the vehicle-mounted ceiling screen and the terminal device when they perform near field communication as the maximum distance in the near field communication distance range, the terminal device and the vehicle-mounted ceiling screen can not only successfully realize near field communication, but also avoid the risk of collision between the vehicle-mounted ceiling screen and the terminal device.

[0096] In one specific embodiment, after detecting the position of the user terminal device, the method further comprises: if the position of the terminal device cannot be detected, detecting the position of the user; controlling the vehicle-mounted ceiling screen to move towards the position close to the user and prompting the user to perform the action of holding the terminal device; and detecting the position of the user terminal device during the movement towards the position close to the user.

[0097] The embodiment is for a user to wish to open the near field communication function of the vehicle ceiling suction screen through voice, but the terminal device has not been held or raised for a long time. That is, the vehicle ceiling suction screen has no moving target and cannot quickly reach the distance of NFC touch-to-touch. At this time, the position of the user who requests to open the near field communication function of the vehicle ceiling suction screen can be determined according to the detection of the user's position, for example, through the monitored pickup area.

[0098] Then, the vehicle ceiling suction screen is controlled to approach the user first. At the same time in the process of approaching the user's position, the vehicle ceiling suction screen is controlled to prompt the user to hold the terminal device for performing near field communication with the vehicle ceiling suction screen through screen text or voice, etc. After detecting that the user holds the terminal device, the vehicle ceiling suction screen is controlled to move towards the terminal device. Specifically, according to the position of the terminal device and the near field communication distance in the three directions of front-back direction, left-right direction and up-down direction realized by the NFC function, the vehicle ceiling suction screen is adaptively approached to the terminal device.

[0099] Here, the specific logic of approaching is the same as the above embodiment. In one embodiment, the vehicle ceiling suction screen is controlled to approach the terminal device until the near field communication requirement is met through the movement of the vehicle ceiling suction screen along the target direction and the linkage with the user's seat. In another embodiment, the vehicle ceiling suction screen is controlled to approach the terminal device until the near field communication requirement is met through the movement of the vehicle ceiling suction screen alone.

[0100] In this embodiment, by controlling the vehicle ceiling suction screen to approach the user's position and issue a prompt when the user's holding of the terminal device is not detected, the user positioning and user guidance can be realized, the idling of the vehicle ceiling suction screen and the waste of resources can be reduced, the intelligent sensing capability of the system and the quality of user interaction can be enhanced, and the user guidance in the waiting state and the pre-adjustment of the position of the vehicle ceiling suction screen can be solved to improve the smoothness of use.

[0101] Based on the above embodiment, further, the control of the vehicle ceiling suction screen to move towards the position close to the user includes: controlling the vehicle ceiling suction screen to move towards the position close to the user at a first speed; and if the position of the terminal device is detected in the process of moving towards the position close to the user, controlling the vehicle ceiling suction screen to move towards the terminal device at a second speed, the second speed being greater than the first speed.

[0102] When the user's holding of the terminal device is not detected, the vehicle ceiling suction screen is controlled to slowly start to approach the user at a first speed, and after the user's holding of the terminal device is detected, the moving speed of the vehicle ceiling suction screen is increased, for example, moving at a second speed higher than the first speed at which the movement starts. In this way, the idling of the vehicle ceiling suction screen and the waste of resources in the waiting state without a clear target can be reduced, the intelligent sensing capability of the system can be enhanced, and the smoothness of use can be improved.

[0103] For the detected terminal device and its position, the approaching speed of the vehicle ceiling suction screen can be controlled to automatically increase, because the user has manually held up the terminal device, and if the approaching speed is too slow, it can cause the user's arm to be sore or its position to change quickly. Therefore, after the user wakes up the NFC function of the vehicle ceiling suction screen and detects the user's terminal device, the moving speed of the vehicle ceiling suction screen is controlled to automatically increase. Moreover, the farther the distance between the vehicle ceiling suction screen and the user, the faster the moving speed of the vehicle ceiling suction screen. The use experience of the NFC function is improved, and the user's arm fatigue, operation difficulty or position instability caused by the slow moving speed of the vehicle ceiling suction screen is reduced. That is, the movement of the vehicle ceiling suction screen is automatically accelerated for the user's handheld terminal device, which overcomes the uncertainty of the user's arm movement and avoids fatigue caused by insufficient moving speed.

[0104] In one specific embodiment, based on the detected position of the terminal device, the vehicle ceiling suction screen is controlled to move towards the direction of approaching the terminal device, including: if multiple terminal devices are detected, prompting the user to select a target terminal device from the multiple terminal devices; and controlling the vehicle ceiling suction screen to move towards the direction of approaching the target terminal device.

[0105] For the application scenario of complex in-vehicle environment, if the user triggers the subjective demand of the near field communication function of the vehicle ceiling suction screen, multiple user handheld terminal devices are detected, or one user holds multiple terminal devices, it is impossible to determine the position of the terminal device approached by the vehicle ceiling suction screen. At this time, the in-vehicle user is prompted to select one terminal device by the vehicle ceiling suction screen in the form of text or voice, and is used to perform near field communication with the vehicle ceiling suction screen, so that the terminal devices that do not need to perform near field communication are put away or lowered, etc., so as to quickly lock the position of the terminal device that performs near field communication.

[0106] If multiple terminal devices are detected to be held up, the system prompts the user to select a target terminal device to achieve quick locking and ensure the accuracy of near field communication and user experience. The multiple terminal device holding up prompt is an optimization level of user interaction, solves the multi-target interference, and realizes the precise movement of the vehicle ceiling suction screen.

[0107] In addition, after the vehicle ceiling suction screen and the user's terminal device implement the NFC one-touch function, it can be prompted that the NFC function has been implemented for the user through the display position or voice of the vehicle ceiling suction screen, so the vehicle ceiling suction screen can be controlled to return to its original position state. If the user selects OK, the vehicle ceiling suction screen can be controlled to automatically return to the original position state. If the user selects No, it means that the user may want to further change the NFC one-touch operation corresponding to the terminal device, so it remains stationary; or it means that the user wants to cancel the NFC one-touch operation corresponding to the terminal device, so it automatically returns to the original position state.

[0108] By controlling the vehicle-mounted ceiling screen to automatically return to the original position after the NFC tap operation is completed, it is ensured that the visual field effect of the vehicle-mounted ceiling screen is continuous and does not affect other use scenarios.

[0109] In the embodiments of the present application, a vehicle-mounted ceiling screen control method is provided. In view of the problem that the current user operation of the vehicle-mounted ceiling screen is complicated, the near field communication function of the vehicle-mounted ceiling screen and the near field communication function of the user terminal device are combined to control the vehicle-mounted ceiling screen to interact with the user terminal device. Specifically, first, in response to a target request operation of a user, the position of the user terminal device is detected, and the target request operation is used to request to turn on the near field communication function of the vehicle-mounted ceiling screen. Then, based on the detected position of the terminal device, the vehicle-mounted ceiling screen is controlled to move towards the terminal device, so that the terminal device and the vehicle-mounted ceiling screen perform near field communication. In this way, based on the request of the user, the near field communication function of the vehicle-mounted ceiling screen can be turned on to realize connection with the user terminal device. The near field communication distance range is small, and the stability of the connection can be ensured when the near field communication distance range is reached, and the signal is not easily interrupted. Moreover, the position of the terminal device used by the user to perform near field communication with the vehicle-mounted ceiling screen is automatically identified, and the vehicle-mounted ceiling screen is controlled to move close to the terminal device, realizing automatic adaptive and fast response of "screen finding terminal device". The distance between the vehicle-mounted ceiling screen and the user terminal device can quickly and accurately reach the near field communication distance range, meeting the near field communication demand, reducing the need for manual intervention of the user, significantly improving the convenience and efficiency of the user using the near field communication function of the vehicle-mounted ceiling screen, improving the use experience of the near field communication function, enhancing the intelligence and human-computer interaction friendliness of in-vehicle interaction, and ensuring the multifunctionality and comfort of the vehicle.

If the first distance is out of the near field communication distance range, the vehicle-mounted ceiling screen is controlled to move towards the terminal device in the front-rear direction based on the first distance until the first distance is within the near field communication distance range. If the second distance and / or the third distance is out of the near field communication distance range, the seat on which the user is seated is controlled to move relative to the vehicle-mounted ceiling screen in the corresponding direction based on the second distance and / or the third distance until the corresponding distance is within the near field communication distance range.
