Also, processor 111 may be a combination of these with a hardware accelerator, etc. Processor 111 controls each part in order to realize various functions of control device 110 based on programs such as firmware, system software, and application software stored in ROM 112 or auxiliary storage device 114, etc. Also, processor 111 executes the processes described later based on the program. Note that part or all of the program may be incorporated in the circuit of processor 111.

[0013] ROM 112 and RAM 113 are the main storage devices of a computer centered around processor 111. ROM 112 is a non-volatile memory used exclusively for reading data.

[0014] RAM 113 is a memory used for reading and writing data. RAM 113 is utilized as a work area, etc. that stores data temporarily used by processor 111 when performing various processes. RAM 113 is typically a volatile memory.

[0015] The auxiliary storage device 114 is an auxiliary storage device of a computer centered around the processor 111. The auxiliary storage device 114 is, for example, an EEPROM (electric erasable programmable read-only memory), an HDD (hard disk drive), or a flash memory. The auxiliary storage device 114 stores, among the above programs, for example, system software and application software. The auxiliary storage device 114 also stores data used by the processor 111 to perform various processes, data generated by the processes in the processor 111, and various setting values.

[0016] The communication interface 115 is an interface for the control device 110 to communicate with other devices. This communication may be wireless communication or wired communication. This communication may also be a mixture of wireless communication and wired communication. The control device 110 communicates with the seat 120, the display device 130, and the external vehicle sensor 140 via the communication interface 115. The control device 110 controls the seat 120, the display device 130, and the external vehicle sensor 140 using this communication.

[0017] The display device 116 displays a screen for notifying various information to the operator of the vehicle 100 or the control device 110. The display device 116 is, for example, a display such as a liquid crystal display or an organic EL (electro-luminescence) display.

[0018] The input device 117 receives operations by the operator of the vehicle 100 or the control device 110. The input device 117 is, for example, a keyboard, a keypad, a touch pad, or a controller. Also, the input device 117 may be a device for voice input. Further, as the display device 116 and the input device 117, a touch panel can also be used. In this case, the display panel included in the touch panel functions as the display device 116. And the pointing device by touch input included in the touch panel functions as the input device 117.

[0019] The bus 118 includes a control bus, an address bus, a data bus, etc., and transmits signals exchanged among the respective parts of the control device 110.

[0020] The seat 120 is a chair on which a person riding in the vehicle 100 sits. The vehicle 100 includes, as an example, a seat 120 for the driver, a seat 120 for the passenger seat, and a seat 120 for the rear seat. The seat 120 includes, as an example, a seat body 131 and an ottoman 132.

[0021] The seat body 131 is a part on which a person riding in the vehicle 100 sits. The seat body 131 includes, for example, a seat surface and a backrest. The seat body 131 may include an armrest, a headrest, etc.

[0022] The ottoman 132 is a part on which a person sitting on the seat body 131 places their feet. The seat body 131 and the ottoman 132 may be connected or separated.

[0023] The seat 120 is deformable. The deformation of the seat 120 includes, for example, the deformation of the ottoman 132, reclining, front-back sliding, changing the seat surface height, changing the position of the armrest, changing the position of the headrest, etc. The seat 120 can be deformed electrically based on the control by the control device 110 for at least a part of the deformation of the seat 120. The deformation of the ottoman 132 includes, for example, changing the height of the ottoman 132, changing the position of the ottoman 132, changing the angle of the ottoman 132, changing the mode of the ottoman 132 with multiple modes, and folding and unfolding the foldable ottoman 132. The seat 120 can be deformed electrically based on the control by the control device 110 for at least a part of the deformation of the ottoman 132.

[0024] The display device 130 is a device for displaying images. The display device 130 is, for example, a display such as a liquid crystal display or an organic EL display, or a projector. The display may be a head-mounted display or a head-up display. The head-mounted display may be a VR (virtual reality) goggles or an AR (augmented reality) goggles, etc. The projector is a device that projects an image onto a projection object by projecting light. The projection object is somewhere in the passenger compartment of the vehicle 100. Examples of the projection destination of the image include the ceiling, wall, door, and floor in the passenger compartment of the vehicle 100, the back side of the seat backrest, the window glass, and the dashboard. Note that a moving image is a kind of image. Also, the image may be a 3D (three-dimensional) image.

[0025] The external sensor 140 is a sensor for external use of the vehicle 100. The external sensor 140 detects, for example, an external object. Note that the object includes organisms such as humans. The external sensor 140 is, for example, a camera, a microphone, an optical sensor, an infrared sensor, a radar, LIDAR (light detection and ranging), or a vibration sensor. The external sensor 140 outputs information indicating the sensing result. The information output by the external sensor 140 is hereinafter referred to as "external information". The vehicle 100 may include a plurality of types of external sensors 140. The vehicle 100 may include a plurality of external sensors 140.

[0026] Hereinafter, the operation of the seat control system 1 according to the embodiment will be described with reference to FIG. 2 and the like. Note that the content of the processing in the following operation description is an example, and various processes capable of obtaining the same result can be appropriately used. FIG. 2 is a flowchart showing an example of the processing by the processor 111 of the control device 110. The processor 111 executes the processing of FIG. 2 based on a program stored in, for example, the ROM 112 or the auxiliary storage device 114.

[0027] The processor 111 of the control device 110 starts the processing shown in FIG. 2, for example, when the display device 130 starts or is about to start displaying an image. Then, the processor 111 ends the processing shown in FIG. 2, for example, when the display device 130 ends or is about to end displaying an image. Alternatively, the processor 111 starts the processing shown in FIG. 2 when the display device 130 starts or is about to start displaying a moving image. Then, the processor 111 ends the processing shown in FIG. 2, for example, when the display device 130 ends or is about to end displaying a moving image. Note that the processor 111 of the control device 110 may control the display device 130 to display an image on the display device 130. Note that the image targeted in the present embodiment is preferably a moving image. This is because the effects of the present embodiment can be easily obtained.

[0028] In step ST11 of FIG. 2, the processor 111 of the control device 110 acquires at least one of the image displayed on the display device 130 and the data indicating what kind of image it is. The processor 111 acquires the image and the data, for example, from the auxiliary storage device 114 or the display device 130.

[0029] In step ST12, the processor 111 performs a process of determining the type of the image being displayed on the display device 130 using at least one of the image acquired in step ST11 and the data acquired in step ST11. As an example, the processor 111 determines whether the image is one of two types, a first type and a second type. The first type is an example of the first category. The second type is an example of the second category.

[0030] The image of the first type is an image that can relax. And the image of the second type is an image other than the image of the first type.

[0031] The processor 111 makes at least one of the following determinations (A1) to (A7), for example. And when any of the determinations made by the processor 111 corresponds, it determines that it is the first type. Alternatively, the processor 111 may determine that it is the first type when the number of corresponding determinations among the determinations made is equal to or more than a predetermined number. Also, points may be set for each determination. And the processor 111 may determine that it is the first type when the total of the points of the corresponding determinations is equal to or more than a predetermined point.

[0032] (A1) It is a moving image without dialogue. (A2) It is a moving image with a dialogue amount of a predetermined amount or less. (A3) It is an image in which no person appears. (A4) It is an image in which the degree of a person appearing is a predetermined amount or less. (A5) It is an image showing a landscape. (A6) It is an image in which the degree of a landscape appearing is a predetermined amount or more. (A7) It is a moving image with a length of a predetermined time or more. (A8) It is a movie. (A9) It is an image in which a predetermined object is shown or the degree of showing is equal to or more than a predetermined level. The predetermined object is, for example, an animal, a starry sky, or nature. (A10) It is an image in which a predetermined object is not shown or the degree of showing is less than or equal to a predetermined level. The predetermined object is, for example, a violent expression or the like. (A11) It is a moving image that includes a predetermined sound or includes the sound to a predetermined level or more. The predetermined sound is, for example, the sound of nature or the chirping of insects or animals. (A12) It is a moving image that does not include a predetermined sound or includes the sound to a predetermined level or less. The predetermined sound is, for example, a shouting voice or a sound at a predetermined volume or more.

[0033] The processor 111 may, for example, calculate a score indicating the possibility that the image is a relaxing image. Then, when the score is equal to or more than a predetermined value, the processor 111 determines that the image is of the first type. The processor 111 calculates the score by, for example, a calculation method including at least any one of the following (B1) to (B5) features.

[0034] (B1) The higher the score, the less dialogue there is in the moving image. (B2) The higher the score, the less the degree to which people are shown in the image. (B3) The higher the score, the more the degree to which a landscape is shown in the image. (B4) The higher the score, the longer the length of the moving image. (A13) When it is a movie, the score is higher than when it is not a movie. (B5) The higher the score, the more the degree to which a predetermined object is shown in the image. The predetermined object is, for example, an animal, a starry sky, or nature. (B6) The higher the score, the less the degree to which a predetermined object is shown in the image. The predetermined object is, for example, a violent expression or the like. (B7) The higher the score, the more the degree to which a predetermined sound is included in the moving image. The predetermined sound is, for example, the sound of nature or the chirping of insects or animals. (B8) The lower the degree of the moving image including the predetermined voice, the higher the score. The predetermined voice is, for example, a shouting voice or a voice above a predetermined volume.

[0035] Further, the processor 111 may determine whether the image is of the first type using AI. That is, the processor 111 may input the image into the learned model to obtain an output indicating whether the image is of the first type.

[0036] From the above, the processor 111 functions as an example of a type determination unit that determines the type of the image displayed on the display device that displays the image in the vehicle interior by performing the process of step ST12.

[0037] In step ST13 of FIG. 2, the processor 111 of the control device 110 determines whether it is determined in the process of step ST12 that the image is of the first type. If the processor 111 determines in the process of step ST12 that the image is of the first type, it determines Yes in step ST13 and proceeds to step ST14.

[0038] In step ST14, the processor 111 acquires a setting (hereinafter referred to as "first setting") indicating what deformed state the seat 120 is to be in when the image is of the first type from the auxiliary storage device 114 or the like. The deformed state of the seat 120 indicated by the first setting is, by default, a state in which a person sitting on the seat 120 can relax. The deformed state of the seat 120 indicated by the default first setting includes, for example, the following states (C1) and (C2). Note that the first setting indicates the state of the seat 120 corresponding to the first type.

[0039] (C1) The ottoman 132 is in a usable state. The state in which the ottoman 132 is usable is, for example, a state in which the foldable ottoman 132 is deployed. The state in which the ottoman 132 is usable is, for example, a state in which the movable ottoman 132 is in a usable position. (C2) The backrest of the seat body 131 is reclined at a predetermined angle. That is, the backrest has fallen backward at a predetermined angle.

[0040] In step ST15, the processor 111 controls the seat 120 to deform it into the state indicated by the first setting obtained in step ST14.

[0041] On the contrary, if the processor 111 does not determine that the image is of the first type in the process of step ST12, it determines No in step ST13 and proceeds to step ST15.

[0042] In step ST16, the processor 111 obtains a setting (hereinafter referred to as "second setting") indicating what deformation state to set the seat 120 to when the image is of the second type from the auxiliary storage device 114 or the like. The deformation state of the seat 120 indicated by the second setting includes, for example, the following states (D1) and (D2) by default. Note that the second setting indicates the state of the seat 120 corresponding to the second type.

[0043] (D1) The ottoman 132 is not available for use. The state where the ottoman 132 is not available for use is, for example, a state where the foldable ottoman 132 is folded. The state where the ottoman 132 is not available for use is, for example, a state where the movable ottoman 132 is not in a usable position. (D2) The backrest of the seat body 131 is not reclined.

[0044] In step ST17, the processor 111 controls the seat 120 to deform it into the state indicated by the second setting obtained in step ST16.

[0045] As described above, the processor 111 functions as an example of a deformation control unit that causes the deformation state of the ottoman provided in the seat in the vehicle interior to be a state corresponding to the type by performing the process of step ST15 or step ST17.

[0046] After the processing in step ST15 or step ST17, the processor 111 proceeds to step ST18.

[0047] In step ST18, the processor 111 determines whether to perform again the process of determining the type of the image being displayed on the display device 130. For example, the processor 111 determines to perform the process again when the image being displayed on the display device 130 is changed. For example, the processor 111 determines to perform the process again when the scene of the image being displayed on the display device 130 is switched. For example, the processor 111 determines to perform the process again when the elapsed time since the process was last performed is equal to or more than a predetermined time. If the processor 111 determines not to perform again the process of determining the type of the image, it determines No in step ST18 and proceeds to step ST19.

[0048] In step ST19, the processor 111 determines whether the seat 120 has been deformed. This deformation is performed, for example, by a person sitting on the seat 120. Also, this deformation may be a manual deformation or an electric deformation. If the seat 120 has not been deformed, the processor 111 determines No in step ST19 and proceeds to step ST20.

[0049] In step ST20, the processor 111 determines whether the vehicle 100 is in an unsafe situation. For example, the processor 111 acquires vehicle exterior information from the vehicle exterior sensor 140. Then, the processor 111 determines whether the exterior of the vehicle 100 is safe using the vehicle exterior information. For example, the processor 111 determines that the vehicle 100 is not safe when there is a suspicious person around the vehicle 100. For example, the processor 111 determines that there is a suspicious person around the vehicle 100 when at least any one of the following (E1) to (E6) applies.

[0050] (E1) A person is within a predetermined distance from the vehicle 100 for a predetermined period or more. (E2) A person has approached within a predetermined distance from the vehicle 100. (E3) There is a person acting suspiciously around the vehicle 100. (E4) A person around the vehicle 100 has uttered a suspicious keyword. (E5) There is a person attempting to do something to the vehicle 100. (E6) A person has attempted to touch or has touched the door of the vehicle 100.

[0051] In addition, the processor 111 may determine that the vehicle 100 is not safe using a known method.

[0052] From the above, the processor 111 functions as an example of a safety determination unit that determines that the vehicle is in an unsafe situation by performing the process of step ST20.

[0053] If the processor 111 does not determine that the vehicle 100 is in an unsafe situation, it determines No in step ST20 and returns to step ST18. Thus, the processor 111 enters a waiting state where it repeats steps ST18 to ST20 until it determines to perform the process of discriminating the type of the image displayed on the display device 130 again, or the seat 120 is deformed, or it determines that the vehicle 100 is in an unsafe situation.

[0054] If the processor 111 determines to perform the process of discriminating the type of the image displayed on the display device 130 again while in the waiting state of repeating steps ST18 to ST20, it determines Yes in step ST18 and returns to step ST11.

[0055] If the seat 120 is deformed while the processor 111 is in the waiting state of repeating steps ST18 to ST20, it determines Yes in step ST19 and proceeds to step ST21.

[0056] In step ST21, the processor 111 rewrites either the first setting or the second setting to indicate the deformed state of the current seat 120. If the processor 111 has determined in the process of the most recent step ST12 that the image is of the first type, it rewrites the first setting. If the processor 111 has determined in the process of the most recent step ST12 that the image is of the second type, it rewrites the second setting.

[0057] For example, in a state where it has been determined in the process of the most recent step ST12 that the image is of the first type, if the ottoman is deformed into a state where it cannot be used, the deformed state indicated by the first setting is changed to a state where the ottoman cannot be used. As a result, from the next time on, when the processor 111 determines that the image is of the first type, it will set the ottoman to a state where it cannot be used. Also, for example, in a state where it has been determined in the process of the most recent step ST12 that the image is of the second type, if the ottoman is deformed into a state where it can be used, the deformed state indicated by the second setting is changed to a state where the ottoman can be used. As a result, from the next time on, when the processor 111 determines that the image is of the second type, it will set the ottoman to a state where it can be used. After the process of step ST21, the processor 111 proceeds to step ST20.

[0058] As described above, by performing the process of step ST21, when the ottoman is deformed into a deformed state different from the state corresponding to the type determined by the type determination unit, the processor 111 functions as an example of a changing unit that changes the state corresponding to the type to the deformed state of the ottoman after the deformation.

[0059] If the processor 111 determines that the vehicle 100 is in a non-safe situation when it is in the waiting state of repeating steps ST18 to ST20, it determines Yes in step ST20 and proceeds to step ST22.

[0060] In step ST22, the processor 111 gives a warning to the person in the vehicle 100 indicating that the vehicle 100 is not safe. The processor 111 causes, for example, at least one of the display device 116 and the display apparatus 130 to display an image indicating that the vehicle 100 is not safe. The processor 111 causes, for example, a sound indicating that the vehicle 100 is not safe to be output from the speaker.

[0061] In step ST23, the processor 111 deforms the seat 120 in order to make the person in the vehicle 100 aware that the vehicle 100 is not safe. The deformed state of the seat 120 after this deformation includes, for example, the states of (D1) and (D2) described above.

[0062] In step ST24, the processor 111 waits for the vehicle 100 to become safe. The processor 111 performs, for example, the same processing as in step ST20, and if it is determined that the vehicle 100 is not in an unsafe situation, it is determined that the vehicle 100 has become safe. If the processor 111 determines that the vehicle 100 has become safe, it determines Yes in step ST24 and returns to step ST11.

[0063] The control device 110 of the embodiment controls the deformed state of the ottoman 122 according to the type of the image displayed by the control device 130. Thereby, the control device 110 of the embodiment can make the deformed state of the ottoman 122 a state suitable for the type of the image. For example, the control device 110 of the embodiment can deform the ottoman 122 so that it can be more relaxed when the control device 130 is displaying a moving image that allows relaxation. Also, since the ottoman 122 is automatically deformed for the person riding in the vehicle 100, the labor of deforming the ottoman 122 is reduced. As described above, the comfort of the person riding in the vehicle 100 is improved.

[0064] Further, when the image displayed by the control device 130 is of the first type, the control device 110 of the embodiment enables the ottoman 122 to be used. And when the image is of the second type, the control device 110 of the embodiment disables the ottoman 122 from being used. Thereby, in the embodiment 100, for example, when the control device 130 is displaying a moving image that allows relaxation, the ottoman 122 can be made available for use so that the user can relax more.

[0065] Also, the control device 110 of the embodiment determines that the image displayed by the control device 130 is of the first type when the image is a moving image without dialogue or an image without a person shown. Such images are likely to be relaxing images such as images showing nature. Therefore, by classifying such images as the first type, the control device 110 of the embodiment can distinguish relaxing images.

[0066] Also, the control device 110 of the embodiment determines that the image is of the first type when the length of the image is equal to or longer than a predetermined time. Such images are likely to be movies. Therefore, by classifying such images as the first type, the control device 110 of the embodiment can enhance the sense of immersion in the movie.

[0067] Also, when the vehicle 100 is not safe, the control device 110 of the embodiment disables the ottoman 122 from being used. Thereby, the control device 110 of the embodiment can make the person sitting on the seat 120 aware that the vehicle is not safe.

[0068] Also, when the vehicle 100 is not safe, the control device 110 of the embodiment deforms the seat 120. Thereby, the control device 110 of the embodiment can make the person sitting on the seat 120 aware that the vehicle is not safe.

[0069] In addition, when the seat is deformed, the control device 110 of the embodiment rewrites the first setting or the second setting. When the first setting is rewritten, from the next time, the deformed state of the seat 120 after the process of step ST15 will be in accordance with the rewritten first setting. Further, when the second setting is rewritten, from the next time, the deformed state of the seat 120 after the process of step ST17 will be in accordance with the rewritten second setting. In this way, the control device 110 of the embodiment enables the seat 120 to be deformed according to the user's preference.

[0070] The above embodiment can be modified as follows. In the above embodiment, the first type of image is an image that allows relaxation. And the second type of image is an image other than the first type. However, the method of classifying the first type of image and the second type of image may be different from the above embodiment.

[0071] In the above embodiment, the processor 111 of the control device 110 discriminates the image being displayed on the display device 130. However, the processor 111 may discriminate the image to be displayed by the display device 130 in the future.

[0072] In the above embodiment, the processor 111 of the control device 110 determines that the vehicle 100 is not safe using the outside vehicle information. However, the processor 111 may receive the input of information indicating that the vehicle 100 is not safe from an external device or the like. And the processor 111 determines that the vehicle 100 is in a non-safe situation in response to receiving the input of the information.

[0073] In the above embodiment, the types of images are two, namely the first type and the second type. However, there may be three or more types of images.

[0074] In the above-described embodiment, the first setting and the second setting can be changed. However, the first setting and the second setting may not be changeable. In this case, the processor 111 does not perform the processes of step ST19 and step ST21 in FIG. 2. That is, if the processor 111 determines No in step ST18, it proceeds to step ST20.

[0075] In the above-described embodiment, the display device 130 is installed inside the vehicle 100. However, the display device 130 may be installed in other locations.

[0076] Each device of the embodiment may be composed of a plurality of devices.

[0077] The processor 111 may implement part or all of the processes implemented by the program in the above-described embodiment by the hardware configuration of a circuit.

[0078] The program that implements the processes of the embodiment is transferred, for example, in a state stored in a non-transitory computer-readable storage medium within the device. However, the device may be transferred in a state where the program is not stored. And the program may be transferred separately and written into the device. The transfer of the program at this time can be realized, for example, by recording it on a removable non-transitory computer-readable storage medium or by downloading via a network such as the Internet or a LAN (local area network).

[0079] As described above, the embodiments of the present invention have been described, but they are shown as examples and do not limit the scope of the present invention. The embodiments of the present invention can be implemented in various modes without departing from the gist of the present invention.
