Therefore, according to the method, a stable and quiet platform can be provided for the first user, and the learning / office / film watching effect and the riding experience of the first user are improved.

Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a method, device, vehicle and storage medium for state control in the field of vehicle technology. Background Art

[0002] Generally speaking, multi-purpose vehicles (MPVs) have a large interior space and comfortable seat design, and more and more people use seatback screens to watch movies, study or work.

[0003] Therefore, how to provide a stable and quiet platform for vehicle users is an urgent problem that needs to be solved. Summary of the invention

[0004] The present application provides a state control method, device, vehicle and storage medium, which can provide a stable and quiet platform for vehicle users and improve the riding experience of the first user.

[0005] In a first aspect, a state control method is provided, which is applied to a vehicle, wherein an in-vehicle screen in the vehicle has a call function of directionally propagating sound, the method comprising: when a first user uses a first seat back screen in the in-vehicle screen, based on posture information of a first seat back corresponding to the first seat back screen, adjusting the first seat back screen to stabilize the first seat back screen, and determining a current driving state of the vehicle, wherein the first user corresponds to the first seat back screen; and based on the driving state, controlling the call function of the first seat back screen to be in a disabled state.

[0006] In the above technical solution, when the first user uses the first seatback screen, the method can adjust the first seatback screen based on the posture information of the first seatback corresponding to the first seatback screen. In this way, when the posture of the first seatback changes, the method can synchronously adjust the first seatback screen, which can keep the relative position between the first user and the first seatback screen stable, and there is no visual angle offset between the first user and the first seatback screen, which can provide a stable learning / working / watching platform for the first user. At the same time, the method controls the call function of the first seatback screen to be disabled based on the driving state of the vehicle. This can not only take into account the impact of the driving state on the state of the call function, but also prohibit the first user from answering and making calls when the vehicle is in certain driving states, so that the first user's learning / working / watching process is not disturbed, and the driver is not disturbed at all. Therefore, the method can provide a stable and quiet platform for the first user and improve the riding experience of the first user.

[0007] In combination with the first aspect, in certain possible implementations, a slide rail is provided on the first seat back, and the first seat back screen can move left and right on the first seat back via the slide rail, and the first seat back screen has a folding function. Based on the posture information of the first seat back corresponding to the first seat back screen, the first seat back screen is adjusted, including: when the posture information includes the roll angle of the first seat back, based on the roll angle, controlling the first seat back screen to move left and right on the first seat back via the slide rail; and / or, when the posture information includes the pitch angle of the first seat back, based on the pitch angle and the folding function, controlling part of the first seat back screen to flip up and down, so as to increase the visual range of the first user on the first seat back screen.

[0008] In the above technical solution, during the driving process, the vehicle will inevitably have different degrees of roll and / or pitch, and at the same time, the first seat back and the first seat back screen thereon will also roll and / or pitch. At this time, if the first user is studying / working / watching movies through the first seat back screen, this will affect the learning / working / watching effect of the first user. The method sets a slide rail on the first seat back, so that when the first seat back tilts, the first seat back screen can be controlled to move in the roll direction through the slide rail, so that the relative position between the first user and the first seat back screen remains relatively stable in the roll direction, and there is no perspective offset between the first user and the first seat back screen, thereby providing the first user with a relatively stable viewing experience of the seat back screen. The method gives the first seat back screen a folding function, so that when the first seat back pitches, the lower half of the screen in the first seat back screen can be controlled to flip upward along the folding axis. This method of adjusting the first seat back screen based on the change of the first user's perspective can increase the visual range of the first user on the first seat back screen, so that the first user can see the content on the lower half of the screen more clearly. Therefore, the method can provide a stable learning / working / movie watching and other platforms for the first user.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, based on the driving state, the call function of the first seat back screen is controlled to be in a disabled state, including: when the driving state is a low-speed state and the vehicle is driving during non-peak hours, the call function of the first seat back screen is controlled to be in a disabled state; when the driving state is a low-speed state and indicates that each user in the vehicle is not in a preset state, the call function of the first seat back screen is controlled to be in a disabled state, and the preset state is used to indicate that the user is in an emergency; when the driving state is a high-speed state, the call function of the first seat back screen is controlled to be in a disabled state; and / or, when the driving state indicates that the driving road condition of the vehicle is a preset road condition, the call function of the first seat back screen is controlled to be in a disabled state, and the preset road condition is used to affect the safe driving of the vehicle.

[0010] In the above technical solution, when the first user uses the first seatback screen, if the vehicle is in a low-speed state and the vehicle is in a non-peak period, the vehicle controls the call function of the first seatback screen to be in a disabled state. At this time, the traffic volume is small and the vehicle is more stable, which can provide a better learning / working / watching environment for the first user. The method of disabling the call function can avoid affecting the first user due to the call process. Therefore, the process can provide a quiet and stable environment for the first user. When the first user uses the first seatback screen, if the vehicle is in a low-speed state and the users in the vehicle are not in a preset state, the vehicle controls the call function of the first seatback screen to be in a disabled state. At this time, the first user has no urgent affairs, and disabling the call function can create a quieter learning / working / watching environment for the first user, while also reducing potential interference to the driver. When the first user uses the first seatback screen, if the driving state is high-speed and / or the driving road conditions are preset road conditions, the vehicle controls the call function to be in a disabled state. This is because the sound generated during the call may affect the comfort of other users, especially at high speeds or complex road conditions, where this interference is particularly obvious. Therefore, disabling the call function can keep the in-car environment quiet and harmonious and improve the first user's riding experience.

[0011] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, based on the driving state, the call function of the first seat back screen is controlled to be in a disabled state, including: when the vehicle is in this driving state, detecting whether the second user is about to trigger the call function associated with the first user on the corresponding first vehicle-mounted screen; when the second user is about to trigger the call function associated with the first user on the first vehicle-mounted screen, displaying a first reminder message on the first seat back screen, the first reminder message being used to remind the first user to choose to participate in the call or to delay the call; when the first user chooses to delay the call, controlling the call function of the first seat back screen to be in a disabled state.

[0012] In the above technical solution, when the vehicle is in driving state, if the second user is about to call the first user who is studying / working / watching a movie, etc., the method displays the first reminder information on the first seatback screen of the first user. In this way, the first user can choose whether to answer the call based on his own needs, and then control the state of the call function based on the choice of the first user, that is, the first user can control the state of the call function. When the first user chooses to delay the call, the method controls the call function of the first seatback screen to be disabled, so that the first user will not spend time on the call, and can also avoid the first user being distracted by the sudden call sound. In addition, delaying the call can also determine that the first user is busy at the current time, which to a certain extent allows the second user to call the first user after a period of time, and also allows the first user to not miss important matters informed by the second user.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, based on the driving state, the call function of the first seat back screen is controlled to be in a disabled state, including: when the vehicle is in this driving state, determining whether there is a frequent communication need between a third user in the vehicle and the first user; when there is a frequent communication need between the third user and the first user, determining whether the current time is within a preset time interval for calls; when the current time is not within the preset time interval, controlling the call function of the first seat back screen to be in a disabled state.

[0014] In the above technical solution, when the third user in the vehicle needs to communicate frequently with the first user, the method determines whether the current time is within the preset time interval for communication. When the current time is not within the preset time interval, the vehicle control call function is disabled. In other words, the method is set with a time period in which a call can be made with the first user, so that other users can only talk with the first user when the current time is within the preset time interval. This method of allocating time slices can ensure that the first user who needs frequent communication but does not want to interrupt learning can study / work / watch movies continuously, as well as communicate with other users as necessary.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, based on the driving state, the call function of the first seatback screen is controlled to be in a disabled state, including: when the vehicle is in the driving state, determining the environmental information around the vehicle; when the environmental information indicates that the visibility of the current driving section is lower than the preset visibility and the tire adhesion of the vehicle is lower than the preset adhesion, determining the straightness of the vehicle based on the visibility and the tire adhesion, and the straightness is used to measure the ability of the vehicle to pass the current driving section; based on the straightness, controlling the call function of the first seatback screen to be in a disabled state.

[0016] In the above technical solution, when the vehicle is in driving state, if the visibility of the current driving section is low and the tire adhesion of the vehicle is low, the method determines the straightness of the vehicle based on visibility and tire adhesion, that is, the ability of the vehicle to pass the current driving section, and then controls the call function to be disabled based on the straightness. In other words, the state of the call function of the first seatback screen is considered from the dimension of the entire vehicle. When the driving conditions of the vehicle are not good, the driver may need to frequently adjust the driving operation to maintain the straightness of the vehicle. By controlling the call function of the first seatback screen to be disabled by the straightness, it can be avoided that unexpected situations during the call (such as sudden excited words, transmission of urgent information, etc.) cause the atmosphere in the car to be tense or the first user suddenly makes large movements, which affects the distribution of the center of gravity of the vehicle, and then affects the driving stability of the driver.

[0017] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the straightness of the vehicle is determined based on the visibility and the tire adhesion, including: dividing the adhesion between the minimum tire adhesion and the preset adhesion to obtain multiple adhesions, each of the multiple adhesions corresponds to a straightness; dividing the visibility between the first visibility and the second visibility according to preset equal parts to obtain multiple visibilities, each of the multiple visibilities corresponds to a straightness, and the visibility is greater than the first visibility and less than the second visibility; based on the multiple adhesions and the corresponding straightness, and the tire adhesion, determining the first straightness corresponding to the tire adhesion, and based on the multiple visibilities and the corresponding straightness, and the visibility, determining the second straightness corresponding to the visibility; determining the straightness based on the first straightness and the second straightness.

[0018] In the above technical solution, the lower the tire adhesion of the vehicle, the greater the impact on the vehicle passing through the current driving section. The lower the visibility of the current driving section, the greater the impact on the vehicle passing through the current driving section. Tire adhesion and the above visibility comprehensively and positively affect the vehicle passing through the current driving section. Therefore, the method first determines the degree of influence of tire adhesion and visibility on the vehicle passing through the current driving section, that is, the corresponding straightness, and then combines the first straightness and the second straightness. This can determine a more accurate straightness, which provides a basis for the subsequent process of controlling the call function of the first seatback screen to be disabled through the straightness.

[0019] In a second aspect, a state control device is provided, which is installed in a vehicle, and the vehicle-mounted screen in the vehicle has a call function of directionally propagating sound. The device includes: a determination module, which is used to adjust the first seat back screen in the vehicle-mounted screen based on the posture information of the first seat back corresponding to the first seat back screen to stabilize the first seat back screen when the first user uses the first seat back screen, and determine the current driving state of the vehicle, and the first user corresponds to the first seat back screen; a control module, which is used to control the call function of the first seat back screen to be disabled based on the driving state.

[0020] In combination with the second aspect, in certain possible implementations, a slide rail is provided on the first seat back, and the first seat back screen can move left and right on the first seat back through the slide rail, and the first seat back screen has a folding function. The device also includes: an adjustment module, used to: when the posture information includes the roll angle of the first seat back, based on the roll angle, control the first seat back screen to move left and right on the first seat back through the slide rail; and / or, when the posture information includes the pitch angle of the first seat back, based on the pitch angle and the folding function, control part of the first seat back screen to flip up and down to increase the visual range of the first user on the first seat back screen.

[0021] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the control module is specifically used to: when the driving state is a low-speed state and the vehicle is driving during a non-peak period, control the call function of the first seat back screen to be in a disabled state; when the driving state is a low-speed state and indicates that each user in the vehicle is not in a preset state, control the call function of the first seat back screen to be in a disabled state, and the preset state is used to indicate that the user is in an emergency; when the driving state is a high-speed state, control the call function of the first seat back screen to be in a disabled state; and / or, when the driving state indicates that the driving road condition of the vehicle is a preset road condition, control the call function of the first seat back screen to be in a disabled state, and the preset road condition is used to affect the safe driving of the vehicle.

[0022] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes: a detection module, which is used to detect whether the second user is about to trigger the call function associated with the first user on the corresponding first vehicle-mounted screen when the vehicle is in the driving state; a display module, which is used to display a first reminder message on the first seat back screen when the second user is about to trigger the call function associated with the first user on the first vehicle-mounted screen, and the first reminder message is used to remind the first user to choose to participate in the call or delay the call; the control module is specifically used to control the call function of the first seat back screen to be disabled when the first user chooses to delay the call.

[0034] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0036] Figure 1 It is a schematic diagram of a scenario of using a vehicle provided in an embodiment of the present application.

[0037] In some embodiments, when rear-seat user A is studying, working, or watching a movie through the seatback screen in the MPV, other users may want to communicate with rear-seat user A for information sharing, or the MPV may be traveling on an uneven road (such as a bumpy road), all of which may affect the study / work / movie-watching effect of rear-seat user A.

[0038] In order to solve the above problems, this application proposes a state control method to provide a stable and quiet platform for vehicle users and improve the riding experience of vehicle users. For details, please refer to the following Figure 2 .

[0039] Figure 2 It is a schematic flow chart of a state control method provided in an embodiment of the present application.

[0040] It should be understood that the state control method provided in the embodiment of the present application can be applied to Figure 1 The vehicle shown (e.g. Figure 1 Specifically, the state control method can be applied to a vehicle controller in the vehicle.

[0041] Exemplarily, the method 200 is applied to a vehicle, wherein the vehicle-mounted screen in the vehicle has a call function of directional sound propagation, such as Figure 2 As shown, the method 200 includes the following steps 201 to 203.

[0042] Step 201, when the first user uses the first seat back screen in the vehicle-mounted screen, the vehicle adjusts the first seat back screen based on the posture information of the first seat back corresponding to the first seat back screen to stabilize the first seat back screen and determine the current driving status of the vehicle. The first user corresponds to the first seat back screen.

[0043] It should be understood that the "vehicle screen has a call function with directional sound propagation" in the above step 201 refers to a call function in which the vehicle screen integrates directional sound emission technology. When a call is made through the call function with directional sound propagation, other users except the two parties in the call can hardly hear each other's call content, which can protect the privacy of the call. In addition, the call sound is propagated in a directional manner. When the vehicle user talks to the target user but not to the first user, the target user can hear the vehicle user's call sound, while the first user can hardly hear it, which can avoid interference with the first user.

[0044] It should also be understood that the first user can use the first seatback screen in the vehicle screen to study, work or watch movies. Accordingly, the first user can trigger the target mode (such as study / work / watch movie mode) on the first seatback screen. After the target mode is triggered by the first user, the vehicle will adjust the first seatback screen based on the posture information of the first seat back corresponding to the first seatback screen, and control the call function of the first seatback screen to be disabled based on the driving state of the vehicle. Among them, adjusting the first seatback screen can make the first seatback screen and the first user in a relatively stable state, and disabling the call function of the first seatback screen can prevent the first user's study / work / watch movie and other processes from being disturbed. Therefore, the "target mode" mentioned above is used to provide a stable and quiet platform for vehicle users. In some embodiments, the first user triggers the target mode on the first seatback screen by clicking the target button, and the target button is used to start the target mode.

[0045] It should also be understood that the "first seat back screen" in the above step 201 is a vehicle-mounted screen, and the first seat back screen is located on the seat back of the first seat in the vehicle (first seat back) and is in close contact with the first seat back.

[0046] It should also be understood that the "posture information of the first seat back" in the above step 201 refers to the angles between the first seat back and the target direction and the target plane, respectively, and the posture information includes the angle between the first seat back and the vertical direction (i.e., the roll angle of the first seat back) and the angle between the first seat back and the corresponding seat cushion (i.e., the pitch angle of the first seat back). The vertical direction refers to the direction perpendicular to the horizontal plane of the vehicle, also known as the gravity direction.

[0047] It should also be understood that “the first user corresponds to the first seatback screen” in the above step 201 is used to indicate the first user who uses the first seatback screen, and the first user is located opposite to the first seatback screen.

[0048] Figure 3 It is a schematic diagram showing the posture information of the first seat back provided in an embodiment of the present application.

[0049] For example, Figure 3 As shown in (a) of FIG. 1 , a side view of the first seat is given, and the pitch angle of the first seat backrest is the angle between the first seat backrest b and the corresponding seat cushion a, that is, ∠1. Figure 3 As shown in (b) in the figure, a rear view of the first seat is given, and the side tilt angle of the first seat back is the angle between the first seat back b (the left edge d on the top) and the vertical direction c, that is, ∠2.

[0050] It should be understood that "adjusting the first seat back screen" in the above step 201 mainly refers to adjusting the position and angle of the first seat back screen relative to the first seat back.

[0051] In one possible implementation, a slide rail is provided on the first seat back, and the first seat back screen can move left and right on the first seat back via the slide rail, and the first seat back screen has a folding function. The vehicle in step 201 adjusts the first seat back screen based on the posture information of the first seat back corresponding to the first seat back screen, including: when the posture information includes the roll angle of the first seat back, the vehicle controls the first seat back screen to move left and right on the first seat back via the slide rail based on the roll angle; and / or, when the posture information includes the pitch angle of the first seat back, the vehicle controls part of the first seat back screen to flip up and down based on the pitch angle and the folding function, so as to increase the visual range of the first user on the first seat back screen.

[0052] It should be understood that the position of the "slide rail" on the first seat back in the above solution is related to the average height of multiple users. Usually, the slide rail is set at a relatively high position on the first seat back. In addition, the direction of the slide rail is perpendicular to the gravity direction. The "first seat back screen has a folding function" in the above solution means that there is a folding axis on the first seat back screen, which is parallel to the direction of the slide rail, and part of the screen in the first seat back screen can be flipped up and down along the folding axis.

[0053] In the above technical solution, during the driving process, the vehicle will inevitably have different degrees of roll and / or pitch, and at the same time, the first seat back and the first seat back screen thereon will also roll and / or pitch. At this time, if the first user is studying / working / watching movies through the first seat back screen, this will affect the learning / working / watching effect of the first user. The method sets a slide rail on the first seat back, so that when the first seat back tilts, the first seat back screen can be controlled to move in the roll direction through the slide rail, so that the relative position between the first user and the first seat back screen remains relatively stable in the roll direction, and there is no perspective offset between the first user and the first seat back screen, thereby providing the first user with a relatively stable viewing experience of the seat back screen. The method gives the first seat back screen a folding function, so that when the first seat back pitches, the lower half of the screen in the first seat back screen can be controlled to flip upward along the folding axis. This method of adjusting the first seat back screen based on the change of the first user's perspective can increase the visual range of the first user on the first seat back screen, so that the first user can see the content on the lower half of the screen more clearly. Therefore, the method can provide a stable learning / working / movie watching and other platforms for the first user.

[0054] In some embodiments, the vehicle controls the first seat back screen to move left and right on the first seat back via the slide rail based on the roll angle, including: the vehicle obtains the height of the first seat back and the maximum movement amount of the first seat back screen on the slide rail; the vehicle determines the tangent value of the roll angle, and determines the product of the tangent value of the roll angle and the height as the first movement amount, and the first movement amount is the movement amount of the first seat back screen from the target position; the vehicle obtains the current position of the first seat back screen, and determines the distance between the current position and the target position; the vehicle determines the difference between the first movement amount and the distance as the second movement amount; based on the second movement amount, the vehicle controls the first seat back screen to move left and right on the first seat back via the slide rail.

[0055] It should be understood that when the first seat back screen is in the initial position (the position after the first seat back screen is installed), the central axis of the first seat back screen passes through the middle position of the slide rail. When the target position is the middle position of the slide rail, the "first movement amount is the movement amount of the first seat back screen from the target position" in the above scheme specifically refers to the movement amount of the central axis of the first seat back screen from the target position. Correspondingly, the "current position of the first seat back screen" in the above scheme specifically refers to the position of the central axis of the first seat back screen. Of course, the target position can also be other positions. In some embodiments, the target position is the position of the left edge of the first seat back screen when the central axis of the first seat back screen passes through the middle position of the slide rail. When the target position is the position of the left edge, the "first movement amount is the movement amount of the first seat back screen from the target position" specifically refers to the movement amount of the left edge of the first seat back screen from the target position. Correspondingly, the "current position of the first seat back screen" specifically refers to the position of the left edge of the first seat back screen.

[0056] In some embodiments, the vehicle controls the first seat back screen to move left and right on the first seat back through the sliding rail based on the second movement amount, including: when the second movement amount is less than or equal to the maximum movement amount and the first seat back tilts to the left, the vehicle controls the first seat back screen to move the second movement amount to the left on the first seat back through the sliding rail; when the second movement amount is less than or equal to the maximum movement amount and the first seat back tilts to the right, the vehicle controls the first seat back screen to move the second movement amount to the right on the first seat back through the sliding rail; when the second movement amount is greater than the maximum movement amount and the first seat back tilts to the left, the vehicle controls the first seat back screen to move the maximum movement amount to the left on the first seat back through the sliding rail; when the second movement amount is greater than the maximum movement amount and the first seat back tilts to the right, the vehicle controls the first seat back screen to move the maximum movement amount to the right on the first seat back through the sliding rail.

[0057] In some embodiments, when the target position is the middle position of the slide rail, if the current position is on the left side of the target position, a "-" needs to be added before the distance; if the current position is on the right side of the target position, a "+" needs to be added before the distance. Correspondingly, for the first movement amount, if the first seat back tilts to the left, a "-" needs to be added before the first movement amount; if the first seat back tilts to the right, a "+" needs to be added before the first movement amount.

[0058] In some embodiments, the vehicle controls part of the screen in the first seat back screen to flip up and down based on the pitch angle and the folding function, including: when the pitch angle is greater than a preset angle, the vehicle determines the difference between the pitch angle and the preset angle as a first offset angle; the vehicle determines the product of the first offset angle and a preset multiple as a second offset angle; the vehicle obtains a first angle between the lower half of the screen in the first seat back screen and a first plane at the current moment, the first plane being the plane where the lower half of the screen was originally installed on the first seat back; the vehicle controls part of the screen in the first seat back screen to flip up and down based on the second offset angle, the first angle and the folding function. the vehicle controls the lower half of the screen in the first seat back screen to flip up and down; when the pitch angle is less than the preset angle, the vehicle determines the difference between the preset angle and the pitch angle as a third offset angle; the vehicle determines the product of the third offset angle and the preset multiple as a fourth offset angle; the vehicle obtains the second angle between the upper half of the screen in the first seat back screen and the second plane at the current moment, the second plane being the plane where the upper half of the screen was originally located when it was installed on the first seat back; based on the fourth offset angle, the second angle and the folding function, the vehicle controls the upper half of the screen in the first seat back screen to flip up and down.

[0059] It should be understood that the "preset angle" in the above solution is 90 degrees. In some embodiments, the preset multiple is 2.

[0060] In some embodiments, the vehicle controls the lower half of the screen in the first seat back screen to flip up and down based on the second offset angle, the first angle and the folding function, including: the vehicle determines a first angle difference between the second offset angle and the first angle; when the second offset angle is greater than the first angle, the vehicle controls the lower half of the screen in the first seat back screen to flip upward by the first angle difference based on the folding function; when the second offset angle is less than the first angle, the vehicle controls the lower half of the screen in the first seat back screen to flip downward by the first angle difference based on the folding function.

[0061] In some embodiments, the vehicle controls the upper half of the screen in the first seat back screen to flip up and down based on the fourth offset angle, the second angle and the folding function, including: the vehicle determines the second angle difference between the fourth offset angle and the second angle; when the fourth offset angle is greater than the second angle, the vehicle controls the upper half of the screen in the first seat back screen to flip downward by the second angle difference based on the folding function; when the fourth offset angle is less than the second angle, the vehicle controls the upper half of the screen in the first seat back screen to flip upward by the second angle difference based on the folding function.

[0062] In some embodiments, when the pitch angle is equal to the preset angle, the vehicle controls the upper half of the screen and the lower half of the screen in the first seat back screen to remain in close contact with the first seat back.

[0063] Figure 4 This is a schematic diagram of adjusting the first seat back screen provided in an embodiment of the present application.

[0064] For example, Figure 4 As shown in (a), when the pitch angle of the first seat back is greater than the preset angle (90 degrees), the vehicle determines the difference between the pitch angle and the preset angle as the first offset angle, and determines the product of the first offset angle and the preset multiple as the second offset angle ∠a1; the vehicle obtains the first angle ∠a2 between the lower half screen f of the first seat back screen and the first plane at the current moment; the vehicle determines the first angle difference ∠a3 between the second offset angle and the first angle; when the second offset angle is greater than the first angle, the vehicle controls the lower half screen of the first seat back screen to flip upward by the first angle difference based on the folding function.

[0065] like Figure 4 As shown in (b), when the pitch angle of the first seat back is less than the preset angle (90 degrees), the vehicle determines the difference between the pitch angle and the preset angle as the third offset angle, and determines the product of the third offset angle and the preset multiple as the fourth offset angle ∠b1; the vehicle obtains the second angle ∠b2 between the upper half of the screen e in the first seat back screen and the second plane at the current moment; the vehicle determines the second angle difference ∠b3 between the fourth offset angle and the second angle; when the fourth offset angle is less than the second angle, the vehicle controls the upper half of the screen in the first seat back screen to flip upward by the second angle difference based on the folding function.

[0066] like Figure 4 As shown in (c), the target position is the middle position of the slide rail, the vehicle determines the tangent value of the roll angle of the first seat back, and determines the product of the tangent value of the roll angle and the height of the first seat back as the first movement amount c1; the vehicle obtains the current position of the first seat back screen, and determines the distance 0 between the current position and the target position; the vehicle determines the difference between the first movement amount and the distance as the second movement amount c1; when the second movement amount is less than or equal to the maximum movement amount and the first seat back tilts to the left, the vehicle controls the first seat back screen to move the second movement amount to the left on the first seat back through the slide rail. Wherein, c01 refers to the position of the central axis when the first seat back screen is in the current position (before moving), and c02 refers to the position of the central axis after the first seat back screen moves.

[0067] like Figure 4As shown in (d), the target position is the middle position of the slide rail, the vehicle determines the tangent value of the roll angle of the first seat back, and determines the product of the tangent value of the roll angle and the height of the first seat back as the first movement amount d1; the vehicle obtains the current position of the first seat back screen, and determines the distance d2 between the current position and the target position; the vehicle determines the difference between the first movement amount and the distance as the second movement amount d3; when the second movement amount is less than or equal to the maximum movement amount and the first seat back tilts to the right, the vehicle controls the first seat back screen to move the second movement amount to the right on the first seat back through the slide rail. Wherein, d01 refers to the position of the central axis when the first seat back screen is in the current position (before moving), and d02 refers to the position of the central axis after the first seat back screen moves. In addition, the current position of the first seat back screen is on the left side of the target position, and a "-" needs to be added before the distance d2, and a "+" needs to be added before the first movement amount d1. The difference between the first movement amount and the distance is actually d1-(-d2)=d1+d2, which is the second movement amount d3.

[0068] In some embodiments, the vehicle in step 201 determines the current driving state of the vehicle, including any one of the following: when the driving speed of the vehicle is less than a preset speed, the vehicle determines that the driving state is a low-speed state; when the driving speed is greater than the preset speed, the vehicle determines that the driving state is a high-speed state; the vehicle obtains the type of road section in front of the vehicle through a vehicle-mounted camera, and when the road section type is a preset road section type, determines that the driving state indicates that the driving road condition of the vehicle is a preset road condition, and the preset road section type is a road section type with a driving difficulty greater than the driving difficulty of a straight and flat section, and the preset road condition is used to affect the safe driving of the vehicle; the vehicle obtains the emotional state of each user in the vehicle, and when the emotional state of each user is not in a preset state, determines that the driving state indicates that the each user in the vehicle is not in a preset state, and the preset state is used to indicate that the user encounters an emergency.

[0069] It should be understood that the "straight and flat road section" in the above scheme refers to a road section where the road slope is less than a preset slope and can be driven in a straight line. In some embodiments, the preset slope is 3°.

[0070] In some embodiments, the preset speed is 60 km / h.

[0071] In some embodiments, the preset road section types are turning sections, steep slope sections, heavy snow sections, congested sections, and narrow road sections.

[0072] In some embodiments, the preset state is an anxious state.

[0073] In some embodiments, the preset state is an anxious state, and a method for determining that the emotional state is a preset state includes: the vehicle extracts features from the facial image of the user to obtain facial features, and the facial features include at least one of eye features, eyebrow features, mouth features, and facial muscle features on the face of the user; when the eye features indicate that the user's pupils are dilated and / or the eyebrow features indicate that the user's eyebrows are in a locked state and / or the mouth features indicate that the user's mouth is in a closed state and / or the facial muscle features indicate that the user's facial muscles are in a contracted state, the vehicle determines that the emotional state is The preset state; or, when the voice signal of the user is detected, the vehicle extracts features of the voice signal to obtain acoustic features of the voice signal, and the acoustic features include at least one of a tone feature, a speaking rate feature, a volume feature, a voiceprint feature and a semantic feature; when the tone feature indicates that the user's tone is rising and / or the speaking rate feature indicates that the user's speaking rate is accelerating and / or the volume feature indicates that the user's volume is increasing and / or the voiceprint feature indicates that the user's voice is trembling and / or the semantic feature indicates that the user is repeating the same sentence, the vehicle determines that the emotional state is the preset state.

[0074] It should be understood that the user's facial features and acoustic features are different in different emotional states. When the emotional state is anxious, the user's eyebrows are tightly locked, vertical wrinkles appear between the two eyebrows, and the two eyebrows are close together; the user's mouth is tightly closed or slightly open; the user's facial muscles will contract, especially the muscles of the forehead and the corrugator muscles will contract; the user's voice will rise, showing a higher tone; the user's speech speed will increase; the user's volume will increase; the user's speech voice will tremble; the user repeats the same word or sentence many times.

[0075] It should also be understood that in the above scheme, the "tone feature" is also called the frequency feature of the sound, and the high and low changes of the sound are used to distinguish the meaning of the language when the user speaks. The "volume feature" is also called the loudness feature of the sound, which refers to the perception of the strength of the sound, which is related to the amplitude of the sound. The larger the amplitude, the louder the sound sounds; the smaller the amplitude, the weaker the sound sounds. In other words, the tone feature mainly involves the frequency change of the sound, which is used to distinguish different meanings in the language; while the volume feature involves the amplitude change of the sound, which affects the loudness of the sound and is the subjective feeling of the strength of the sound.

[0076] In some embodiments, the vehicle in step 201 adjusts the first seat back screen based on the posture information of the first seat back corresponding to the first seat back screen, including: the vehicle determines whether the zero gravity function of the first seat to which the first seat back belongs is turned on; when the zero gravity function of the first seat is not turned on, the vehicle adjusts the first seat back screen based on the posture information of the first seat back corresponding to the first seat back screen.

[0077] It should be understood that the "zero gravity function" in the above solution refers to a function that makes the body of the first user in a floating state by adjusting the angle and position of the first seat. This can reduce the pressure on the spine and joints, promote blood circulation, help muscles relax, and enhance the relaxation effect. When the zero gravity function of the first seat is turned on and the first user sits on the first seat, the upper body of the first user is 45 degrees to the ground, and the calf of the first user is 45 degrees to the ground.

[0078] Step 202: Based on the driving status, the vehicle controls the call function of the first seatback screen to be disabled.

[0079] It should be understood that "the calling function of the first seatback screen is in a disabled state" in the above step 202 specifically means that the first user cannot make calls to other users through the calling function of the first seatback screen, nor can he answer calls from other users through the calling function of the first seatback screen.

[0080] In some embodiments, after controlling the call function of the first seatback screen to be disabled in step 202, the method 200 also includes: the vehicle controls the call function of other vehicle-mounted screens to be disabled, or the vehicle controls the call function of other vehicle-mounted screens to be enabled.

[0081] In the above technical solution, the vehicle further controls the call function of other in-vehicle screens to be in a disabled state, which can provide the first user with an absolutely quiet platform for learning / working / watching in the cabin, so that the first user will not be affected by the in-vehicle environment in the learning / working / watching effect, and can improve the first user's riding experience. Or, the vehicle further controls the call function of other in-vehicle screens to be in an enabled state, which can provide the first user with a relatively quiet platform for learning / working / watching in the cabin, which can not only meet the communication needs of other users through the call function with directional sound propagation, but also provide the first user with a relatively quiet learning / working / watching environment as much as possible, and improve the first user's riding experience.

[0082] The process of "controlling the call function of the first seatback screen to be disabled" is described in several ways as follows.

[0083] The first one is related to the driving status of the vehicle.

[0084] In one possible implementation, step 202 includes: when the driving state is a low-speed state and the vehicle is driving during a non-peak period, the vehicle controls the call function of the first seat back screen to be in a disabled state; when the driving state is a low-speed state and indicates that each user in the vehicle is not in a preset state, the vehicle controls the call function of the first seat back screen to be in a disabled state, and the preset state is used to indicate that the user is in an emergency; when the driving state is a high-speed state, the vehicle controls the call function of the first seat back screen to be in a disabled state; and / or, when the driving state indicates that the driving road condition of the vehicle is a preset road condition, the vehicle controls the call function of the first seat back screen to be in a disabled state, and the preset road condition is used to affect the safe driving of the vehicle.

[0085] It should be understood that the "off-peak hours" in the above scheme refer to the time periods other than rush hour and holidays.

[0086] In the above technical solution, when the first user uses the first seatback screen, if the vehicle is in a low-speed state and the vehicle is in a non-peak period, the vehicle controls the call function of the first seatback screen to be in a disabled state. At this time, the traffic volume is small and the vehicle is more stable, which can provide a better learning / working / watching environment for the first user. The method of disabling the call function can avoid affecting the first user due to the call process. Therefore, the process can provide a quiet and stable environment for the first user. When the first user uses the first seatback screen, if the vehicle is in a low-speed state and the users in the vehicle are not in a preset state, the vehicle controls the call function of the first seatback screen to be in a disabled state. At this time, the first user has no urgent affairs, and disabling the call function can create a quieter learning / working / watching environment for the first user, while also reducing potential interference to the driver. When the first user uses the first seatback screen, if the driving state is high-speed and / or the driving road conditions are preset road conditions, the vehicle controls the call function to be in a disabled state. This is because the sound generated during the call may affect the comfort of other users, especially at high speeds or complex road conditions, where this interference is particularly obvious. Therefore, disabling the call function can keep the in-car environment quiet and harmonious and improve the first user's riding experience.

[0087] In some embodiments, the urgent matter is any one of a medical emergency matter and a request for help matter.

[0088] The second one is related to the choice of the first user.

[0089] In one possible implementation, step 202 includes: when the vehicle is in the driving state, the vehicle detects whether the second user is about to trigger the call function associated with the first user on the corresponding first vehicle-mounted screen; when the second user is about to trigger the call function associated with the first user on the first vehicle-mounted screen, the vehicle displays a first reminder message on the first seatback screen, and the first reminder message is used to remind the first user to choose to participate in the call or delay the call; when the first user chooses to delay the call, the vehicle controls the call function of the first seatback screen to be disabled.

[0090] It should be understood that the "second user is about to trigger the call function associated with the first user on the corresponding first vehicle-mounted screen" in the above solution specifically means that the second user is about to call the first user through the call function on the first vehicle-mounted screen. The "delayed call" in the above solution means that the first user is not convenient to answer (reject) the call for some reason and chooses to delay the call for a period of time.

[0091] In the above technical solution, when the vehicle is in driving state, if the second user is about to call the first user who is studying / working / watching a movie, etc., the method displays the first reminder information on the first seatback screen of the first user. In this way, the first user can choose whether to answer the call based on his own needs, and then control the state of the call function based on the choice of the first user, that is, the first user can control the state of the call function. When the first user chooses to delay the call, the method controls the call function of the first seatback screen to be disabled, so that the first user will not spend time on the call, and can also avoid the first user being distracted by the sudden call sound. In addition, delaying the call can also determine that the first user is busy at the current time, which to a certain extent allows the second user to call the first user after a period of time, and also allows the first user to not miss important matters informed by the second user.

[0092] The third type is related to the communication needs of other users.

[0093] In one possible implementation, step 202 includes: when the vehicle is in the driving state, the vehicle determines whether there is a frequent communication need between the third user in the vehicle and the first user; when there is a frequent communication need between the third user and the first user, the vehicle determines whether the current time is within a preset time interval for conversation; when the current time is not within the preset time interval, the vehicle controls the call function of the first seatback screen to be disabled.

[0094] It should be understood that the “frequent communication needs between the third user and the first user” in the above solution specifically means that the third user and the first user need to communicate with each other multiple times through the call function within a period of time.

[0095] In the above technical solution, when the third user in the vehicle needs to communicate frequently with the first user, the method determines whether the current time is within the preset time interval for communication. When the current time is not within the preset time interval, the vehicle control call function is disabled. In other words, the method is set with a time period in which a call can be made with the first user, so that other users can only talk with the first user when the current time is within the preset time interval. This method of allocating time slices can ensure that the first user who needs frequent communication but does not want to interrupt learning can study / work / watch movies continuously, as well as communicate with other users as necessary.

[0096] In some embodiments, the vehicle determines whether there is a need for frequent communication between a third user in the vehicle and the first user, including: when the third user is a driver and the vehicle is a commercial vehicle, the vehicle determines that there is no need for frequent communication between the third user and the first user; when the third user is a driver and the vehicle is a private vehicle, the vehicle determines that there is a need for frequent communication between the third user and the first user; or, when the third user is a driver and the vehicle is in an unsteady state, the vehicle determines that there is no need for frequent communication between the third user and the first user; when the third user is a driver and the vehicle is in a stable state, the vehicle determines that there is a need for frequent communication between the third user and the first user; or, when the third user is not a driver, the vehicle determines the degree of association between the third user and the first user; when the degree of association is less than a preset degree of association, the vehicle determines that there is no need for frequent communication between the third user and the first user; when the degree of association is greater than or equal to the preset degree of association, the vehicle determines that there is a need for frequent communication between the third user and the first user.

[0097] In some embodiments, the vehicle determines the degree of association between the third user and the first user, including: the vehicle obtains a first facial image of the third user and a second facial image of the first user; the vehicle extracts facial features on the first facial image to obtain a first feature, and extracts facial features on the second facial image to obtain a second feature; the vehicle determines the similarity between the first feature and the second feature as the degree of association; or, in the case where there is physical interaction between the third user and the first user, the vehicle determines the degree of association based on the intimacy of the physical interaction behavior between the third user and the first user, and the intimacy is positively correlated with the degree of association.

[0098] The fourth type is related to the vehicle’s ability to negotiate the current section of road.

[0099] In one possible implementation, step 202 includes: when the vehicle is in the driving state, the vehicle determines the environmental information around the vehicle; when the environmental information indicates that the visibility of the current driving section is lower than the preset visibility and the tire adhesion of the vehicle is lower than the preset adhesion, the vehicle determines the straightness of the vehicle based on the visibility and the tire adhesion, and the straightness is used to measure the ability of the vehicle to pass the current driving section; based on the straightness, the vehicle controls the call function of the first seatback screen to be disabled.

[0100] It should be understood that the "environmental information" in the above solution includes weather condition information and road environment information. The weather condition information includes weather type, visibility, light intensity, humidity and temperature, etc., and the road environment information includes the flatness of the driving road, road slope, water accumulation and ice conditions, etc.

[0101] It should also be understood that the "preset visibility" in the above scheme refers to the critical visibility at which the vehicle can pass through the current driving section. When the actual visibility is lower than or equal to the preset visibility, the vehicle is not allowed to pass through the current driving section, and when the actual visibility is greater than the preset visibility, the vehicle is allowed to pass through the current driving section. The "preset adhesion" in the above scheme refers to the critical tire adhesion at which the vehicle can pass through the current driving section. When the actual tire adhesion is less than or equal to the preset adhesion, the vehicle cannot pass through the current driving section, and when the actual tire adhesion is greater than the preset adhesion, the vehicle can pass through the current driving section.

[0102] It should also be understood that the "straightness" in the above scheme can be regarded as the degree of difficulty of the vehicle passing the current driving section under the influence of visibility and tire adhesion. The smaller the straightness, the lower the ability of the vehicle to pass the current driving section and the greater the degree of difficulty. When the visibility is the same, the smaller the tire adhesion, the more difficult it is for the vehicle to pass the current driving section. When the tire adhesion is the same, the lower the visibility, the more difficult it is for the vehicle to pass the current driving section. In addition, the straightness is expressed as a percentage.

[0103] In the above technical solution, when the vehicle is in driving state, if the visibility of the current driving section is low and the tire adhesion of the vehicle is low, the method determines the straightness of the vehicle based on visibility and tire adhesion, that is, the ability of the vehicle to pass the current driving section, and then controls the call function to be disabled based on the straightness. In other words, the state of the call function of the first seatback screen is considered from the dimension of the entire vehicle. When the driving conditions of the vehicle are not good, the driver may need to frequently adjust the driving operation to maintain the straightness of the vehicle. By controlling the call function of the first seatback screen to be disabled by the straightness, it can be avoided that unexpected situations during the call (such as sudden excited words, transmission of urgent information, etc.) cause the atmosphere in the car to be tense or the first user suddenly makes large movements, which affects the distribution of the center of gravity of the vehicle, and then affects the driving stability of the driver.

[0104] In a possible implementation, the vehicle determines the straightness of the vehicle based on the visibility and the tire adhesion, including: the vehicle divides the adhesion between the minimum tire adhesion and the preset adhesion to obtain multiple adhesions, each of the multiple adhesions corresponds to a straightness; the vehicle divides the visibility between the first visibility and the second visibility according to preset equal parts to obtain multiple visibilities, each of the multiple visibilities corresponds to a straightness, and the visibility is greater than the first visibility and less than the second visibility; the vehicle determines a first straightness corresponding to the tire adhesion based on the multiple adhesions and the corresponding straightness, and the tire adhesion, and determines a second straightness corresponding to the visibility based on the multiple visibilities and the corresponding straightness, and the visibility; the vehicle determines the straightness based on the first straightness and the second straightness.

[0105] It should be understood that the "minimum tire adhesion" in the above solution is 0 N. In addition, the first visibility is the minimum visibility, and the second visibility is the maximum visibility. In some embodiments, the first visibility is 100 meters, and the second visibility is 25 kilometers.

[0106] In the above technical solution, the lower the tire adhesion of the vehicle, the greater the impact on the vehicle passing through the current driving section. The lower the visibility of the current driving section, the greater the impact on the vehicle passing through the current driving section. Tire adhesion and the above visibility comprehensively and positively affect the vehicle passing through the current driving section. Therefore, the method first determines the degree of influence of tire adhesion and visibility on the vehicle passing through the current driving section, that is, the corresponding straightness, and then combines the first straightness and the second straightness. This can determine a more accurate straightness, which provides a basis for the subsequent process of controlling the call function of the first seatback screen to be disabled through the straightness.

[0107] In some embodiments, the vehicle determines the straightness based on the first straightness and the second straightness, including: the vehicle determines a first product value between the first straightness and the second straightness; the vehicle determines a difference between a first preset value and the first product value as the straightness; or, the vehicle determines a first average value between the first straightness and the second straightness; the vehicle determines the difference between the first preset value and the first average value as the straightness; or, the vehicle determines an average value between the first difference and the second difference as the straightness, the first difference being the difference between the first preset value and the first product value, and the second difference being the difference between the first preset value and the first average value.

[0108] In some embodiments, the first preset value is 1.

[0109] The fifth type is related to the display content or usage time of the first seat back screen.

[0110] In some embodiments, step 202 includes: when the vehicle is in the driving state, the vehicle obtains the type of display content of the first seatback screen and the usage time of the first seatback screen; when the type is a preset type, the vehicle controls the call function of the first seatback screen to be disabled, and the preset type is a type that helps the first user to make progress; or, when the usage time is less than the preset time, the vehicle controls the call function of the first seatback screen to be disabled.

[0111] In some embodiments, the preset type is any one of a document type, a course video type, a data analysis type, and a code type.

[0112] It should be understood that Word documents and Portable Document Format (PDF) files belong to the document type; academic course videos and professional skills training videos belong to the document type; spreadsheets belong to the data analysis type; and programming code belongs to the code type.

[0113] In the above technical solution, when the vehicle is in motion, if the first user watches a preset type of display content through the first seatback screen, it indicates that the first user is in a period of serious study / work / movie watching, etc., and the method controls the call function of the first seatback screen to be disabled. This can ensure that the first user's serious study / work / movie watching, etc. process is not disturbed, thereby improving the first user's riding experience. When the vehicle is in motion, if the first user studies / works / movies, etc. on the first seatback screen for a short period of time (usage time), it indicates that the first user has just started studying / works / movies, and the first user's serious study / works / movies, etc. process should not be disturbed, so the call function can be controlled to be disabled.

[0114] The sixth type is related to the user characteristics of the first user.

[0115] In some embodiments, step 202 includes: when the vehicle is in the driving state, the vehicle obtains the age range of the first user; when the age range is within a preset age range, the vehicle controls the call function of the first seatback screen to be disabled, and the preset age range is used to indicate that the first user is within the age range of studying in a target school or working in a company, and the target school includes primary school and above schools.

[0116] In the above technical solution, when the vehicle is in driving state, if the first user studies / works through the first seatback screen, and the age of the first user is within the preset age range, it indicates that the first user has great study pressure or work pressure. At this time, the method controls the call function of the first seatback screen to be disabled. This enables the first user to continue studying / working and complete the study / work task, ensures that the first user's serious study / work process is not disturbed, and improves the study / work efficiency of the first user.

[0117] The seventh type is related to the driver’s choice.

[0118] In some embodiments, step 202 includes: when the vehicle is in the driving state, the vehicle displays a second reminder message on the vehicle screen corresponding to the driver, and the second reminder message is used to remind the driver to select the state of the call function of the first seat back screen; when the driver selects the disabled state, the vehicle controls the call function of the first seat back screen to be in the disabled state.

[0119] In the above technical solution, when the vehicle is in motion, the driver can directly control the state of the call function of the first seatback screen. This can give the driver certain control rights, such as forcibly turning off (disabling) the call function of the first seatback screen when necessary, especially in situations involving driving safety or important communication.

[0120] Figure 5 It is a structural diagram of a state control device provided in an embodiment of the present application.

[0121] Exemplarily, the device 500 is installed in a vehicle, and the vehicle screen in the vehicle has a call function of directional sound propagation, such as Figure 5 As shown, the device 500 includes:

[0122] a determination module 501, configured to adjust the first seatback screen to stabilize the first seatback screen based on the posture information of the first seat back corresponding to the first seatback screen when the first user uses the first seatback screen in the vehicle-mounted screen, and to determine the current driving state of the vehicle, wherein the first user corresponds to the first seatback screen;

[0123] The control module 502 is used to control the calling function of the first seatback screen to be disabled based on the driving status.
