Description

Technical Field

[0001] This application relates to the field of human-computer interaction technology, and in particular to a control method, control system and vehicle for an in-vehicle screen. Background Technology

[0002] Currently, most in-vehicle ceiling-mounted screens are fixed. While the screen angle is adjustable, the fore-and-aft position cannot be adjusted according to the seating positions of front and rear passengers. Furthermore, if the front driver is tall and needs to adjust the backrest angle, their headrest or head may collide with the screen. To avoid this, the screen must be adjusted around its axis towards the roof, making it difficult to achieve a comfortable viewing angle for rear passengers. Existing technology includes sliding screens that allow for fore-and-aft adjustment, but due to limited interior space, if one rear passenger wants to watch a movie while the other wants to work using the small table on the back of the front seat, the large screen may interfere with the work passenger's head, reducing their comfort.

[0003] In related technologies, the position of the front seats is adjusted to prevent front passengers from bumping their heads on the screen, but this sacrifices the comfortable driving posture of the front passengers. Although the size of the projected image is adjusted according to the number and position of the passengers in the car, it still cannot meet the needs of all passengers and affects the riding experience. Summary of the Invention

[0004] This application provides a method for controlling an in-vehicle screen, a control system, and a vehicle, aiming to improve the existing technology that sacrifices the comfortable driving posture of front-seat passengers for rear-seat movie viewers and fails to meet the needs of all passengers, thus affecting the riding experience.

[0005] A first aspect of this application provides a method for controlling an in-vehicle screen. The in-vehicle screen is connected to a movable component via a support member. The movable component adjusts the screen position of the in-vehicle entertainment screen, and the support member adjusts the screen height and screen angle of the in-vehicle screen. The method includes the following steps: after responding to a viewing instruction from at least one in-vehicle occupant, determining whether the in-vehicle occupant is a viewing occupant or a non-viewing occupant based on the received viewing signal; acquiring the seat posture, number and position distribution of the viewing occupants, and the seat posture of the driver and front passenger. The viewing instruction is used for... The playback control of the in-vehicle screen includes: determining the extreme position of the in-vehicle screen based on the seat parameters of the driver and passenger; determining the target screen position and target screen height based on the extreme position of the in-vehicle screen, the number and position distribution of the movie-watching occupants; determining the target screen angle of the in-vehicle screen based on the target screen position, the target screen height, and the seat posture of the movie-watching occupants; and controlling at least one of the support member and the movable component to adjust the in-vehicle screen based on the target screen position, target screen height, and target screen angle.

[0006] Based on the aforementioned technical means, this application embodiment can determine whether the occupants in the vehicle are movie viewers or non-movie viewers based on the viewing signal received by the vehicle. The posture of the driver and front passenger seats is used as a constraint condition to determine the screen's extreme position, fundamentally avoiding the risk of collision between the screen and the front passenger's head, while maintaining comfortable driving posture. Based on the extreme position of the in-vehicle screen, the number and location distribution of movie viewers, the target screen position and height are determined. Simultaneously, based on the target screen position, target screen height, and the seat posture of the movie viewers, the target screen angle is determined. This fully considers the viewing preferences of movie viewers and non-movie viewers, intelligently adjusting the position and height of the in-vehicle screen to ensure the best viewing experience for movie viewers, while providing ample headroom for non-movie viewers, avoiding any sense of oppression or interference from the screen, and greatly improving the overall vehicle's ride comfort.

[0007] Optionally, determining the extreme position of the in-vehicle screen based on the seat parameters of the driver and passenger seats includes: obtaining a first calibration table for the driver and passenger seats, wherein the first calibration table is a correspondence table of seat position, seat height, seat back tilt angle, and headrest position; extracting the seat position, seat height, and seat back tilt angle from the seat parameters of the driver and passenger seats, and querying the first calibration table using the seat position, seat height, and seat back tilt angle as indexes to obtain the headrest position of the driver and passenger seats; and determining the extreme position of the in-vehicle screen based on the headrest position of the driver and passenger seats.

[0008] Based on the above technical means, the embodiments of this application can determine the headrest position by consulting a first calibration table based on the seat position, seat height, and seat back tilt angle of the driver and passenger seats, and determine the limit position of the vehicle screen based on the headrest position of the driver and passenger seats. The calibration method ensures the adjustable range of the vehicle screen, thus ensuring the absolute comfort and safety of the front-seat occupants.

[0009] Optionally, determining the target screen position and target screen height of the vehicle-mounted screen based on the extreme positions of the vehicle-mounted screen, the number and location distribution of the movie-watching occupants, includes: obtaining a second calibration table of the vehicle-mounted screen, wherein the second calibration table is a correspondence table of the extreme positions of the vehicle-mounted screen, the number and location distribution of the movie-watching occupants, and the screen position and screen height of the vehicle-mounted screen; and querying the second calibration table using the extreme positions of the vehicle-mounted screen and the number and location distribution of the movie-watching occupants as indexes to obtain the target screen position and target screen height of the vehicle-mounted screen.

[0010] Based on the above technical means, the embodiments of this application can determine the target screen position and target screen height of the vehicle screen by querying the second calibration table according to the extreme position of the vehicle screen, the number of moviegoers and their position distribution. By comprehensively considering multiple constraints, the optimal solution is output under multi-objective collaborative optimization, which accurately meets the needs of moviegoers and improves the riding experience of the passengers.

[0011] Optionally, before determining the target screen angle of the vehicle screen based on the target screen position, the target screen height, and the seating posture of the movie-watching occupant, the method further includes: obtaining the number and location distribution of non-movie-watching occupants; and correcting the target screen position and target screen height of the vehicle screen based on the number and location distribution of non-movie-watching occupants.

[0012] Based on the above-mentioned technical means, the embodiments of this application can adjust the target screen position and target screen height of the vehicle screen according to the number and location distribution of non-viewing passengers, thereby ensuring the viewing needs of viewing passengers while meeting the space needs of non-viewing passengers, and greatly improving the riding comfort and safety of non-viewing passengers.

[0013] Optionally, the step of correcting the target screen position and target screen height of the vehicle screen based on the number and location distribution of the non-viewing passengers includes: obtaining a third calibration table of the vehicle screen, wherein the third calibration table is a correspondence table of the extreme positions of the vehicle screen, the number and location distribution of the viewing passengers, the number and location distribution of the non-viewing passengers, and the screen position and screen height of the vehicle screen; using the extreme positions of the vehicle screen, the number and location distribution of the viewing passengers, and the number and location distribution of the non-viewing passengers as indexes, querying the third calibration table to obtain the target screen position and target screen height of the vehicle screen.

[0014] Based on the aforementioned technical means, this application embodiment can query a third calibration table based on the extreme position of the vehicle screen, the number and location distribution of movie-watching passengers, and the number and location distribution of non-movie-watching passengers to obtain the target screen position and target screen height of the vehicle screen. This achieves global optimization through multi-factor collaborative decision-making, effectively solving the spatial comfort problem for all passengers and ensuring the best viewing experience for movie-watching passengers. At the same time, it provides sufficient headroom for non-movie-watchers, avoiding any sense of oppression or interference from the screen, and greatly improving the overall ride comfort of the vehicle.

[0015] Optionally, determining the target screen angle of the vehicle screen based on the target screen position, the target screen height, and the seat posture of the viewer includes: obtaining a fourth calibration table of the vehicle screen, wherein the fourth calibration table is a correspondence table of the target screen position, the target screen height, the seat posture of the viewer, and the screen angle of the vehicle screen; and querying the fourth calibration table using the target screen position, the target screen height, and the seat posture of the viewer as indexes to obtain the target screen angle of the vehicle screen.

[0016] Based on the aforementioned technical means, in this embodiment of the application, the comfort of watching a movie depends not only on the distance and height of the screen, but also on the relative angle between the screen and the user's eyes. Furthermore, different users have different heights and sitting habits, so even if they are sitting in the same position, their eye height and line of sight will be different. Therefore, this application determines the target screen angle of the in-vehicle screen by querying the fourth calibration table based on the target screen position, target screen height, and the seat posture of the movie-watching passenger, thereby achieving precise visual optimization and greatly improving the movie-watching passenger's experience.

[0017] Optionally, before determining the target screen angle of the in-vehicle screen based on the target screen position, the target screen height, and the seat posture of the movie-watching occupant, the method further includes: obtaining the height and weight of the movie-watching occupant and a fifth calibration table, wherein the fifth calibration table is a correspondence table between the height and weight of the movie-watching occupant and the seat posture parameters of the movie-watching occupant; using the height and weight of the movie-watching occupant as an index, querying the fifth calibration table to obtain the target seat posture parameters of the movie-watching occupant; and adjusting the seat posture of the movie-watching occupant according to the target seat posture parameters.

[0018] Based on the above-mentioned technical means, the embodiments of this application can obtain the target seat posture parameters of the moviegoer by querying the fifth calibration table according to the height and weight of the moviegoer, and adjust the seat posture of the moviegoer based on the target seat posture parameters, thereby improving the physiological comfort of the moviegoer during long-term movie watching and enhancing personalized service and movie watching experience.

[0019] A second aspect of this application provides a control system for an in-vehicle screen, comprising a support member and a movable component; an in-vehicle screen connected to the movable component via the support member, the movable component adjusting the screen position of the in-vehicle entertainment screen, and the support member adjusting the screen height and screen angle of the in-vehicle screen; and a controller connected to both the support member and the movable component, thereby controlling at least one of the support member and the movable component to implement the control method for the in-vehicle screen described in the above embodiment, in order to adjust the in-vehicle screen.

[0020] Optionally, the movable component includes a first guide rail, a second guide rail, and a third guide rail. The third guide rail is disposed between the first guide rail and the second guide rail and moves along the first guide rail and the second guide rail. The support member is connected to the third guide rail and moves along the third guide rail. One end of the support member connected to the third guide rail is disposed in a first universal joint structure, and the other end of the support member connected to the vehicle screen is disposed in a second universal joint structure. The first universal joint structure is used to adjust the screen height of the vehicle entertainment screen, and the second universal joint structure is used to adjust the screen angle of the vehicle entertainment screen.

[0021] A third aspect of this application provides a vehicle that includes a control system for an in-vehicle screen as described in the above embodiments.

[0022] Therefore, this application has at least the following beneficial effects: This application embodiment can dynamically determine the safe limit position of the screen based on the real-time posture of the driver and passenger seats, effectively avoiding collision risks and ensuring the driver's operating comfort. It can also comprehensively consider information such as the height, weight, number, location distribution, and viewing intentions of moviegoers, and through a pre-calibrated optimization model, adjust the seating posture of the rear seats and the position, height, and angle of the in-vehicle entertainment screen in conjunction with these factors. This provides moviegoers with a personalized and immersive cinema experience that conforms to human factors engineering, while intelligently avoiding head space for non-movie occupants, taking into account the comfort and safety of all occupants in the vehicle, and improving the intelligence, humanization, and safety of the in-vehicle entertainment system.

[0023] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0027] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] In the related technology (1), the sensor information of the front seat and the opening information of the rear entertainment screen are received. The sensor information of the front seat is used to indicate that the front seat includes the passenger. The initial position information of the passenger in the front seat is determined. The position deviation is determined according to the initial position information and the preset standard position information. If the position deviation exceeds the preset safety threshold, the position of the seat is adjusted to correct the position deviation, thereby avoiding the passenger's head from hitting the display screen and improving the vehicle driving safety performance.

[0029] However, to prevent front-seat passengers from bumping their heads on the screen, the position of the front seats will be adjusted. But this may sacrifice the comfortable driving posture of the front-seat passengers, especially for the driver, which is not conducive to safe and comfortable driving.

[0030] In related technology (2), the seating position information of passengers in the rear seats of a vehicle is obtained, and the seat travel of the rear seats of a vehicle with passengers is obtained based on the seating position information; when a single person is sitting in the rear seat of a single-row vehicle based on the seating position information, the posture control parameters of the vehicle rear screen are determined based on the seating position information and the seat travel; and the posture control of the vehicle rear screen is performed based on the posture control parameters.

[0031] However, the position and angle of the rear screen can only be adjusted when there is only one person in the rear seat of the vehicle, so that the position and angle of the rear screen are more suitable for the passengers and provide them with a better travel experience. As a result, it still cannot meet the comfort needs of passengers when there are multiple people in the vehicle.

[0032] In related technology (3), when a movie-watching mode start command is received, the system detects whether there are occupants in the second row and above seats to obtain occupant detection results; based on the occupant detection results, the size of the projected image is adjusted to a preset size, and the second row of seats is controlled to move longitudinally and laterally by a preset distance and rotate by a preset angle, as well as to tilt the backrests of the second row of seats by a preset angle; or, based on the occupant detection results, the size of the projected image is adjusted to a preset size, and the second row of seats is controlled to move longitudinally by a preset distance and to tilt the backrests of the second row of seats by a preset angle. However, this method cannot avoid the impact on the headroom of non-movie-watchers in the second row when using a large screen, resulting in poor comfort.

[0033] The following description, with reference to the accompanying drawings, outlines a method for controlling an in-vehicle screen, a control system, and a vehicle according to embodiments of this application.

[0034] Specifically, Figure 1 This is a flowchart illustrating a method for controlling an in-vehicle screen according to an embodiment of this application.

[0035] like Figure 1As shown, the control method for the in-vehicle screen involves connecting the in-vehicle screen to a movable component via a support member. The movable component adjusts the screen position of the in-vehicle entertainment screen, while the support member adjusts the screen height and screen angle. The method includes the following steps: In step S101, after responding to the viewing instruction of at least one occupant in the vehicle, the occupant is determined to be a viewing occupant or a non-viewing occupant based on the received viewing signal. The seat posture, number and position distribution of the viewing occupants, as well as the seat posture of the driver and front passenger are obtained. The viewing instruction is used for playback control of the in-vehicle screen. It is understood that, according to the embodiments of this application, the occupants in the vehicle can be determined as movie viewers or non-movie viewers based on the movie viewing signal received by the vehicle, and the seat postures of the driver and front passenger, the seat postures of movie viewers, the number of people and their position distribution can be obtained, so as to facilitate the subsequent adjustment of the screen position, screen height and screen angle of the in-vehicle screen.

[0036] It should be noted that the movie-watching command is triggered by the occupant actively clicking a virtual button on the vehicle's touchscreen interface. This command requests the vehicle's entertainment system to enter "movie-watching mode," essentially acting as a switch to activate this mode. The movie-watching signal, once the system enters "movie-watching mode," is used to determine whether an occupant is a movie-watcher or not. For example, after triggering "movie-watching mode," an option to watch a movie may be displayed on the screen corresponding to the occupant's location. Clicking the desired option generates the movie-watching signal.

[0037] For example, each individual seat in the rear of the vehicle has a small touchscreen integrated into its armrest. When a passenger initiates "movie mode" via voice or touchscreen gesture, a selection interface automatically pops up on the touchscreen of each rear seat. This selection interface displays virtual buttons for watching and not watching. Each passenger's touchscreen gesture triggers the corresponding virtual button for watching or not watching, thus determining whether the passenger is a movie viewer or not based on their viewing preference. For instance, if the vehicle is a four-seater, and the passenger on the right side of the second row clicks the corresponding button to watch on the touchscreen, while the passenger on the left side of the second row clicks the corresponding button to not watch, then the passenger on the right side of the second row is the movie viewer, and the passenger on the left side of the second row is the non-movie viewer.

[0038] Alternatively, each passenger's personal smart terminal can connect to the vehicle's infotainment system via a wireless network. Once the cinema mode is activated, a corresponding page selection interface for the in-vehicle application will pop up on the mobile device connected to the vehicle's network. This selection interface displays virtual buttons for watching and not watching, as well as a map showing the distribution of all passenger positions (the specific content displayed on the interface can be customized depending on the vehicle model). Based on the passenger's input of their seating position and viewing preference, the system determines whether the passenger is a movie-watching passenger or not.

[0039] In step S102, the extreme position of the vehicle screen is determined based on the seat parameters of the driver and passenger. Based on the extreme position of the vehicle screen, the number of viewers and their location distribution, the target screen position and target screen height are determined. It is understood that the embodiments of this application can determine the extreme position of the in-vehicle screen based on the seat parameters of the driver and passenger seats. Based on the extreme position of the in-vehicle screen, the number and position distribution of the movie-watching passengers, the target screen position and target screen height of the in-vehicle screen are determined. The posture of the driver and passenger seats is used as a constraint condition for determining the extreme position of the screen, which fundamentally avoids the risk of the screen colliding with the head of the front passenger, while not sacrificing their comfortable driving posture and ensuring the best viewing experience for the movie-watching passengers.

[0040] In this embodiment of the application, determining the extreme position of the vehicle screen based on the seat parameters of the driver and passenger seats includes: obtaining a first calibration table for the driver and passenger seats, wherein the first calibration table is a correspondence table of seat position, seat height, seat back tilt angle, and headrest position; extracting the seat position, seat height, and seat back tilt angle from the seat parameters of the driver and passenger seats, and querying the first calibration table using the seat position, seat height, and seat back tilt angle as indexes to obtain the headrest positions of the driver and passenger seats; and determining the extreme position of the vehicle screen based on the headrest positions of the driver and passenger seats.

[0041] It is understood that, in this embodiment of the application, the headrest position can be determined by consulting a first calibration table based on the seat position, seat height, and seat back tilt angle of the driver and passenger seats. The limit position of the in-vehicle screen can be determined based on the headrest position of the driver and passenger seats. The calibration method ensures the adjustable range of the in-vehicle screen and ensures the absolute comfort and safety of the front-seat occupants.

[0042] It should be noted that this application can monitor the position, height, and backrest tilt angle of the driver and front passenger seats in real time. Once adjustments to these parameters are detected, the limit position of the in-vehicle screen needs to be further confirmed to ensure the absolute comfort and safety of the front passengers. The first calibration table calibrates the final position of the headrest for different front seat positions, heights, and backrest tilt angles; the minimum distance between the final position of the front headrest and the in-vehicle screen position is pre-set to generate the adjustable range of the in-vehicle screen.

[0043] Specifically, this application can use sensors to monitor the seat position, seat height, and seat back tilt angle of the driver and passenger seats respectively. This allows the determination of the final position of the headrest corresponding to any combination of the three variables of the driver and passenger seats. The ultimate position of the in-vehicle screen is determined by selecting the more rearward headrest and adding a preset safety distance. The minimum distance between the final position of the front seat headrest and the position of the in-vehicle screen is set, such as L=100mm, without specific limitation.

[0044] In this embodiment of the application, determining the target screen position and target screen height of the vehicle screen based on the extreme position of the vehicle screen, the number of moviegoers and their location distribution includes: obtaining a second calibration table of the vehicle screen, wherein the second calibration table is a correspondence table of the extreme position of the vehicle screen, the number of moviegoers and their location distribution, the screen position and screen height of the vehicle screen; using the extreme position of the vehicle screen, the number of moviegoers and their location distribution as indexes, querying the second calibration table to obtain the target screen position and target screen height of the vehicle screen.

[0045] It is understood that, according to the embodiments of this application, the target screen position and target screen height of the vehicle screen can be determined by querying the second calibration table based on the extreme position of the vehicle screen, the number of moviegoers and their position distribution. By comprehensively considering multiple constraints, the optimal solution output under multi-objective collaborative optimization is achieved, which accurately meets the needs of moviegoers and improves the riding experience of the passengers.

[0046] Taking a vehicle with three rows of seats as an example, this application determines the optimal screen position based on the number of rear passengers, the seating positions of the second and third row passengers, and whether the passengers have viewing needs. The needs of rear passengers are shown in Table 1 below.

[0047] Table 1 Rear Passenger Requirements

[0048] It should be noted that ○ indicates that the seat is occupied, a blank space without ○ indicates that the seat is unoccupied, √ indicates that the optimal screen position and angle are available in that case, and / indicates that the case does not exist. Since the screen needs to be at a certain distance from the center of the occupant's eye ellipse during viewing (e.g., ≥700mm), it is only necessary to consider whether the second-row occupants intend to watch the movie; for those who do not intend to watch, their headroom should be avoided. For the third-row occupants, even if they do not wish to watch, the screen will not affect their headroom, therefore, there is no need to specify a standard for the third-row occupants who do not wish to watch.

[0049] Therefore, this application can recommend a suitable screen position for all moviegoers based on the different seating positions of passengers in the second and third rows, and automatically adjust the position, height, and angle of the screen.

[0050] In this embodiment of the application, when determining whether all occupants in the vehicle want to watch the movie, the number of occupants in the vehicle is obtained, and the viewing intention of the occupants in the vehicle is determined to be whether they all want to watch the movie. When the number of occupants who want to watch the movie is the same as the total number of occupants in the vehicle, it is determined that all occupants in the vehicle want to watch the movie. For example, if there are a total of 4 occupants in the back row, and all 4 occupants in the vehicle want to watch the movie, then the viewing status of the occupants in the vehicle is determined to be the state of all wanting to watch the movie.

[0051] If the second row consists of two individual seats, and only one of the two occupants wants to watch a movie (e.g., the left-seat passenger wants to watch while the right-seat passenger doesn't), the system can move the entire in-vehicle screen laterally to the side of the passenger who wants to watch (e.g., to the left). Since the width of the in-vehicle screen is approximately equal to the width of a seat, the screen can be perfectly positioned directly in front of the passenger who wants to watch, while completely avoiding the space above the head of the passenger who doesn't want to watch (the right-seat passenger), thus avoiding any sense of oppression or obstruction of their view.

[0052] If the second row is a single, connected two-seater, the system can move the screen directly above only one passenger if that passenger wants to watch a movie. Since the screen itself is only half the width of the seat, even if it's not completely against the side, it occupies far less space than the entire seat width, naturally leaving most of the space for the other passenger and effectively reducing interference with those not watching the movie.

[0053] In step S103, the target screen angle of the vehicle screen is determined based on the target screen position, target screen height, and the seat posture of the spectator. Based on the target screen position, target screen height, and target screen angle, at least one of the support member and movable component is controlled to adjust the vehicle screen. It is understood that the embodiments of this application can determine the target screen angle of the vehicle screen based on the target screen position, target screen height, and the seating posture of the occupants. Based on the target screen position, target screen height, and target screen angle, at least one of the support members and movable components is controlled to adjust the vehicle screen. This fully considers the viewing intentions of both occupants and non-occupants, intelligently adjusting the position and height of the vehicle screen to ensure the best viewing experience for occupants while providing sufficient headroom for non-occupants, avoiding any sense of oppression or interference from the screen, and greatly improving the overall ride comfort of the vehicle.

[0054] In this embodiment of the application, before determining the target screen angle of the vehicle screen based on the target screen position, target screen height, and the seat posture of the movie-watching occupants, the method further includes: obtaining the number and location distribution of non-movie-watching occupants; and correcting the target screen position and target screen height of the vehicle screen based on the number and location distribution of non-movie-watching occupants.

[0055] It is understood that the embodiments of this application can adjust the target screen position and target screen height of the vehicle screen according to the number and location distribution of non-viewing passengers, thereby ensuring the viewing needs of viewing passengers while meeting the space needs of non-viewing passengers, and greatly improving the riding comfort and safety of non-viewing passengers.

[0056] It should be noted that the in-vehicle screen of this application can automatically make way for the head space of passengers who do not want to watch movies, which not only provides the best viewing angle for movie viewers, but also ensures the head comfort of non-movie viewers.

[0057] In this embodiment of the application, the target screen position and target screen height of the vehicle screen are corrected according to the number and location distribution of non-viewing passengers. This includes: obtaining a third calibration table of the vehicle screen, wherein the third calibration table is a correspondence table of the extreme position of the vehicle screen, the number and location distribution of viewing passengers, the number and location distribution of non-viewing passengers, and the screen position and screen height of the vehicle screen; using the extreme position of the vehicle screen, the number and location distribution of viewing passengers, and the number and location distribution of non-viewing passengers as indexes, querying the third calibration table to obtain the target screen position and target screen height of the vehicle screen.

[0058] It is understood that, according to the embodiments of this application, the target screen position and target screen height of the vehicle screen can be obtained by querying the third calibration table based on the extreme position of the vehicle screen, the number and position distribution of movie-watching passengers, and the number and position distribution of non-movie-watching passengers. This achieves global optimization through multi-factor collaborative decision-making, which not only effectively solves the spatial comfort problem of all passengers and ensures the best viewing experience for movie-watching passengers, but also leaves sufficient head space for non-movie-watching passengers, avoiding the screen from causing a sense of oppression or interference, and greatly improving the overall riding comfort of the vehicle.

[0059] In this embodiment of the application, before determining the target screen angle of the vehicle screen based on the target screen position, target screen height, and the seat posture of the movie-watching occupant, the method further includes: obtaining the height and weight of the movie-watching occupant and a fifth calibration table, wherein the fifth calibration table is a table showing the correspondence between the height and weight of the movie-watching occupant and the seat posture parameters of the movie-watching occupant; using the height and weight of the movie-watching occupant as an index, querying the fifth calibration table to obtain the target seat posture parameters of the movie-watching occupant; and adjusting the seat posture of the movie-watching occupant according to the target seat posture parameters. It is understood that, according to the embodiments of this application, the target seat posture parameters of the moviegoer can be obtained by querying the fifth calibration table based on the height and weight of the moviegoer, and the seat posture of the moviegoer can be adjusted based on the target seat posture parameters, thereby improving the physiological comfort of the moviegoer during long-term movie watching and enhancing personalized service and movie watching experience.

[0060] It should be noted that, due to the subjective evaluation of the viewing posture of people with different height and weight combinations, a fifth calibration table is formed with two variables: height and weight. The target seat posture parameters include the seat back tilt angle and leg rest angle. Thus, an optimal viewing posture matrix is ​​calibrated based on the occupant's height and weight, and an optimal seat back tilt angle and leg rest angle are automatically adjusted for different height and weight combinations.

[0061] In this embodiment of the application, determining the target screen angle of the vehicle screen based on the target screen position, target screen height, and the seat posture of the viewer includes: obtaining a fourth calibration table of the vehicle screen, wherein the fourth calibration table is a correspondence table of the target screen position, target screen height, the seat posture of the viewer, and the screen angle of the vehicle screen; and querying the fourth calibration table using the target screen position, target screen height, and the seat posture of the viewer as indexes to obtain the target screen angle of the vehicle screen.

[0062] It is understood that, in this embodiment of the application, the comfort of watching a movie depends not only on the distance and height of the screen, but also on the relative angle between the screen and the user's eyes. Furthermore, different users may have different eye heights and line of sight even when sitting in the same position due to differences in height and sitting posture. Therefore, this application determines the target screen angle of the in-vehicle screen by querying the fourth calibration table based on the target screen position, target screen height, and the seat posture of the movie-watching occupant, thereby achieving precise visual optimization and greatly improving the movie-watching occupant's experience.

[0063] According to the vehicle screen control method proposed in this application, the safe limit position of the screen is dynamically determined based on the real-time posture of the driver and passenger seats, effectively avoiding collision risks and ensuring the driver's operating comfort. It can also comprehensively consider information such as the height, weight, number, location distribution, and viewing intentions of moviegoers, and through a pre-calibrated optimization model, adjust the seating posture of the rear seats and the position, height, and angle of the vehicle entertainment screen in conjunction with these factors. This provides moviegoers with a personalized and immersive cinema experience that conforms to human factors engineering, while intelligently avoiding head space for non-movie occupants, taking into account the comfort and safety of all occupants in the vehicle, and improving the intelligence, humanization, and safety of the vehicle entertainment system.

[0064] The following will combine Figure 2 The control method for the vehicle screen in this application is described in detail below: Step 1: Upon receiving the movie viewing mode command, calculate the final position of the headrests of the two front seats, and use the more rearward value as the basis for determining the ultimate position of the in-vehicle screen. Move the headrests backward by a distance L to determine the ultimate position of the in-vehicle screen.

[0065] The screen's maximum position remains unchanged as long as the front seats are not adjusted. If the front seats are adjusted, the screen's maximum position will change accordingly.

[0066] Step 2: Based on the gravity sensors in the seats, detect whether there are passengers sitting on each seat. If there are passengers who do not want to watch the movie, they can select the option not to watch the movie. The passengers who want to watch the movie continue to input their height and weight to adjust the position of their seats. Based on the above information, the controller can calculate the position of the seats of the passengers who want to watch the movie, the extreme position of the in-vehicle screen, the number and position distribution of the passengers who want to watch the movie, as well as the optimal position, height and angle of the screen (for the second-row passengers who do not want to watch the movie, the screen can be moved left or right to avoid their head space and ensure their comfort and safety). Finally, the automatic adjustment of the screen and seats is completed (such as Figure 5 and 6 ).

[0067] Step 3: After the above automatic adjustment is completed, if the vehicle occupants are not comfortable or not used to the recommended position, they can also adjust the screen and seats by themselves.

[0068] Step 4: After receiving the command to exit the movie-watching mode, the screen automatically retracts (such as Figure 7 ), and the seats of the passengers who want to watch the movie are automatically adjusted to the position before watching the movie.

[0069] In summary, the present application can determine the current extreme farthest position of the screen according to the seat positions of the current front-row drivers and passengers, realize the linkage control of the screen and the front-row seats, and ensure the comfort and safety of the front-row personnel. It can also integrate the information of the rear-row passengers, realize the linkage control of the screen and the rear-row seats, provide a comfortable sitting posture and screen viewing angle for the rear-row movie-watching passengers, and at the same time ensure the head space of the rear-row non-movie-watching passengers.
