[0085] The functional component 7 is a device that performs functions to adjust the seat body and the surrounding environment of the seat body to improve the comfort and convenience of the seated person sitting on the seat body. Figure 1 , Figure 2 As shown, the functional component 7 includes: a movable part 10, which moves a part of the seat body between a normal position and a protruding position protruding toward the seated person than the normal position; a sound output part 11, which outputs sound; a vibration part 12, which imparts vibration to the seated person; an air conditioning part 13, which blows air toward the seated person; a notification part 14, which makes an emergency notification to the outside of the vehicle; and a display part 15, which displays information to the seated person.

[0086] The movable part 10, the sound output part 11, the vibration part 12, the air conditioning part 13, the notification part 14 and the display part 15 of the functional component 7 are respectively arranged in the seat body. In addition, the functional component 7 can also be arranged in a place other than the seat body in the vehicle where the seat body is arranged.

[0087] The movable part 10 is a device provided inside the seat back 1 and the seat cushion 2 for kneading the seated person. The movable part 10 is, for example, an air chamber that operates in a manner that causes the side portions of the seat back 1 and the seat cushion 2 to protrude. The movable part 10 is controlled by the control unit 8, and bulges toward the seated person's side by sealing in compressed air, and protrudes from a normal position to a protruding position. Moreover, the movable part 10 contracts by discharging the sealed compressed air, and returns to the normal position. When the seated person sits on the seat cushion 2, the seated person operates a switch not shown in the figure, or the control unit 8 detects biological information, and seals compressed air into the air chamber to adjust the movable range of the air chamber.

[0088] In addition, the movable part 10 may be configured to be operated by a mechanical mechanism (a link mechanism or a hinge mechanism, etc.) In addition, the movable part 10 may be configured to supply air to the air chamber by a motor type or hydraulic type drive device, etc.

[0089] The sound output unit 11 is a speaker device that is provided on the headrest 3 and outputs sound toward the seated person. The sound output unit 11 is controlled by the control unit 8 and can output sound to calm the seated person or to inform the seated person of information.

[0090] Furthermore, the sound output unit 11 is provided on the headrest 3 , but the present invention is not limited thereto and the sound output unit 11 may be provided on the seat back 1 , the seat cushion 2 , the armrest 4 , or the like.

[0091] The vibration unit 12 is a device for applying vibration to the seated person, which is provided inside the seat back 1 and the seat cushion 2. The vibration unit 12 is controlled by the control unit 8 to apply stimulation to the seated person or to inform the seated person of information.

[0092] Furthermore, the vibration part 12 is provided inside the seat back 1 and the seat cushion 2, but is not limited thereto, and may be provided in the headrest 3, the armrest 4, the ottoman 5, or the like.

[0093] The air conditioning unit 13 is a device provided on the seat back 1 and the seat cushion 2 for blowing air toward the seated person. In detail, the air conditioning unit 13 is controlled by the control unit 8 to supply the seated person with regulated temperature cold air or warm air from the blowing outlets provided on the surface of the seat back 1 and the seat cushion 2.

[0094] The air conditioning unit 13 can cool down a seated occupant whose body temperature rises by blowing cold air to the seated occupant's neck to prevent heat stroke, or can blow warm air to the seated occupant's legs to relieve symptoms of poor physical condition.

[0095] In addition, the air conditioning unit 13 is controlled by the control unit 8 to supply air containing aromatic components from the air outlet toward the seated person. The air conditioning unit 13 can relax the seated person by releasing the aroma of flowers, plants, fruits, etc., for example.

[0096] The notification unit 14 is a vehicle emergency notification device that is installed on the seat cushion 2 and communicates with the emergency notification center to notify the meaning or status of an emergency such as an accident or illness. The notification unit 14 is controlled by the control unit 8 and can notify the state of the seated person to the emergency notification center outside the vehicle. For example, if the seated person is unconscious based on the pulse or blood pressure of the seated person, the communication with the emergency notification center can be performed automatically to perform a vehicle emergency notification.

[0097] The display unit 15 is a display device installed in the seat body or the vehicle to display information to the seated person. The display unit 15 is, for example, a tablet terminal or a display installed in the seat body or the vehicle. The display unit 15 is controlled by the control unit 8 to display biological information, emotions, fatigue, etc. of the seated person or fellow passengers.

[0098] In addition, the seat body may be provided with a functional component 7 other than the above-mentioned device. For example, the functional component 7 may also include a lighting device provided on the seat body. In addition, the functional component 7 may also be configured to adjust the seat body and the surrounding environment of the seat body by other methods.

[0099] The control unit 8 incorporates a control circuit for controlling the seat drive unit 6 and the functional component 7. The control unit 8 is connected to the high link drive unit 6a, the reclining drive unit 6b, the tilting drive unit 6c, the foot drive unit 6d of the seat drive unit 6, and the movable portion 10, the sound output unit 11, the vibration unit 12, the air conditioning unit 13, the notification unit 14, and the display unit 15 of the functional component 7. Each structure is connected so as to be able to communicate with each other via a bus.

[0100] In addition, the vehicle seat S may be equipped with various actuators, input devices, output devices, and various sensors in addition to these.

[0101] The communication unit 9 wirelessly transmits and receives data between the vehicle seat S, the wearable device W, and the portable terminal SP via the in-vehicle network. Specifically, the communication unit 9 receives biological information, posture information, and position information from the wearable device W.

[0102] <<Wearable devices>>

[0103] The wearable device W has a function as a pulse oximeter, for example, by reading and analyzing the change in oxygen concentration of hemoglobin in the blood from the wrist of the occupant wearing it based on the rate of change of absorbance, it can read biological information such as heart rate. Figure 1 As shown, the wearable device W has the shape of a watch worn on the wrist. In addition, the wearable device W is not limited to the shape of a watch, and may also be in the shape of a wristband, a ring, a glasses, a clip, etc.

[0104] like Figure 2 As shown, the wearable device W includes: a biosensor 20 for detecting the biometric information of the seated person; a position detection unit 21 for detecting the position information of the seated person; a posture detection unit 22 for detecting the posture information of the seated person; and a device communication unit 23 for communicating with the vehicle seat S and the portable terminal SP.

[0105] The wearable device W (second wearable device) worn by the fellow passenger detects the biological information of the fellow passenger through the biosensor 20, similarly to the wearable device W worn by the seated person, and communicates with the vehicle seat S and the portable terminal SP through the device communication unit 23. In addition, the wearable device W worn by the fellow passenger is configured to detect the posture information and position information of the fellow passenger through the position detection unit 21 and the posture detection unit 22.

[0106] The biometric sensor 20 detects biometric information of the seated person or the fellow passenger, and transmits the biometric information to the vehicle seat S via the device communication unit 23. Examples of the biometric information acquired by the biometric sensor 20 include heart rate, pulse, body temperature, sweating, blood pressure, water content, blood oxygen concentration, breathing rhythm, breathing depth, and the like.

[0107] For example, when the heart rate detected by the biosensor 20 is higher than usual, it can be inferred that the seated person or fellow passenger is in an excited state. In addition, when the body temperature, pulse, and sweat volume are higher and the blood pressure is lower than usual, it can be inferred that there is a concern about heat stroke. In addition, when the body temperature is very high and the blood pressure is very low compared to usual, it can be inferred that there is a concern about severe heat stroke (impairment of consciousness, etc.). In addition, when the pulse is high and the breathing depth is shallow compared to usual, it can be inferred that there is a possibility of drinking. In addition, when the blood pressure is high and the water content is low compared to usual, it can be inferred that there is a concern about traveler's thrombosis. In addition, when the blood oxygen concentration is lower than usual, it can be inferred that the fatigue level is high. In addition, when the heart rate is low and the breathing depth is deep compared to usual, it can be inferred that there is sleepiness.

[0108] The position detection unit 21 detects the position information of the seated person, and transmits the position information to the vehicle seat S via the device communication unit 23. The position detection unit 21 is, for example, a Global Positioning System (GPS) sensor, and can detect the position information of the seated person.

[0109] For example, based on the position information detected by the position detection unit 21, if the user stays in a store that provides alcohol for a long time, it can be estimated that the user is likely to drink alcohol.

[0110] The posture detection unit 22 detects the posture information of the seated person and transmits the posture information to the vehicle seat S via the device communication unit 23. The posture detection unit 22 is, for example, an acceleration sensor or an angular velocity sensor (gyro sensor), and can detect the seated posture of the seated person.

[0111] For example, when the seated posture detected by the posture detection unit 22 remains the same for a predetermined period of time, it can be estimated that there is a concern about traveler's thrombosis.

[0112] The device communication unit 23 transmits and receives data between the vehicle seat S, the wearable device W, and the portable terminal SP via the in-vehicle network. Specifically, the device communication unit 23 transmits biological information, posture information, and position information to the vehicle seat S.

[0113] <<Hardware structure of vehicle seats>>

[0114] like Figure 2 As shown, the vehicle seat S includes a control unit 8 for controlling the seat drive unit 6 and the functional component 7. The control unit 8 has a control circuit, which mainly includes a central processing unit (CPU) as a central computing device, a read only memory (ROM) as a storage device, a random access memory (RAM), a hard disk drive (HDD), etc.

[0115] The CPU is a central processing unit that executes various programs or controls various parts. That is, the CPU reads programs from the ROM or HDD and uses the RAM as a work area to execute the programs. The CPU controls each structure and performs various calculations according to the programs stored in the ROM or HDD.

[0116] The ROM stores various programs and various data, and the RAM temporarily stores programs and data as a work area.

[0117] The HDD may also be a solid state drive (SSD), which stores various programs including an operating system and various data.

[0118] <<Functions of the control unit>>

[0119] Next, refer to Figure 2 to Figure 6 The functions of the control unit 8 will be described. The functions of the control unit 8 are respectively realized by the cooperation of hardware devices (specifically, microprocessor unit (MPU) and memory) and software devices (control circuit) constituting an electronic control unit (ECU).

[0120] like Figure 2 As shown, the control unit 8 includes: an acquisition unit 30, which acquires biological information obtained from the wearable device W; an emotion estimation unit 31, which estimates the emotions of the seated occupant and the fellow passengers; a physical condition estimation unit 32, which estimates the physical condition of the seated occupant and the fellow passengers; a drinking estimation unit 33, which estimates the drinking degree of the seated occupant and the fellow passengers; a posture estimation unit 34, which estimates the seating posture of the seated occupant and the fellow passengers; a blood pressure estimation unit 35, which estimates the blood pressure index of the seated occupant and the fellow passengers; a fatigue estimation unit 36, which estimates the fatigue degree of the seated occupant and the fellow passengers; and a sleepiness estimation unit 37, which estimates the sleepiness degree of the seated occupant and the fellow passengers.

[0121] (Acquisition Unit 30)

[0122] The acquisition unit 30 acquires biological information of the seated person and the fellow passenger, posture information of the seated person, and position information of the seated person acquired from the wearable device W via the communication unit 9. The control unit 8 estimates the state of the seated person and the fellow passenger by the emotion estimation unit 31, the physical condition estimation unit 32, the drinking estimation unit 33, the posture estimation unit 34, the blood pressure estimation unit 35, the fatigue estimation unit 36, and the sleepiness estimation unit 37 based on the biological information, posture information, and position information of the seated person and the fellow passenger acquired by the acquisition unit 30. In addition, the control unit 8 controls the seat drive unit 6 and the functional component 7 based on the state of the seated person and the fellow passenger estimated by each estimation unit.

[0123] In addition, the acquisition unit 30 may also be configured to acquire identification information of the seated person and the fellow passengers. Here, the so-called identification information is information for identifying the seated person (personal authentication), for example, corresponding to the seated person and the fellow passengers' identifier (ID) information, image information representing a facial image or a fingerprint image, voiceprint information, etc.

[0124] The identification information may also be acquired by communicating with a portable terminal SP held by a seated person or a passenger. In this case, if a person holding a portable terminal SP sits on a vehicle seat S, the communication unit 9 may also automatically acquire the identification information of the seated person or a passenger by communicating with the portable terminal SP of the seated person or a passenger. In addition, the identification information may be acquired by the seated person or a passenger inputting the identification information from the portable terminal SP and receiving data related to the content of the input operation. Alternatively, the identification information may be acquired by recording the voice of the seated person or a passenger using a microphone installed in the vehicle.

[0125] (Emotion estimation unit 31)

[0126] The emotion estimation unit 31 estimates the emotions of the seated person and the fellow passengers based on the biometric information acquired by the acquisition unit 30 .

[0127] Specifically, the emotion estimation unit 31 estimates the emotions (excited state, relaxed state, etc.) of the seated person and the fellow passengers based on the biological information acquired by the acquisition unit 30. The emotion estimation unit 31 uses a learning model constructed by machine learning to calculate an emotion index based on, for example, the heart rate or breathing rhythm as biological information, and estimates the emotions of the seated person and the fellow passengers.

[0128] The parameters for calculating the emotion index are not limited to the heart rate or the breathing rhythm. For example, when the biosensor 20 detects the electroencephalogram data of the seated person, the emotion estimation unit 31 may estimate whether the seated person is anxious or happy based on the electroencephalogram data.

[0129] Furthermore, the emotions of the seated person and the fellow passengers may be estimated based on the posture information acquired by the acquisition unit 30. For example, when the seated person is in a relaxed sitting posture, it may be estimated that the emotion index is lower (the degree of relaxation is increased).

[0130] When the emotion index of the seat occupant estimated by the emotion estimating unit 31 is equal to or greater than a threshold value, the control unit 8 controls the seat driving unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0131] Specifically, when the control unit 8 determines that the emotion index calculated by the emotion estimation unit 31 is above a preset threshold value (for example, the anxiety level is high and the state is excited), for example, the seat cushion 2 is raised by the high link driving unit 6a, the seat back 1 is tilted backward by the reclining driving unit 6b, the front part of the seat cushion 2 is raised by the tilt driving unit 6c, and the footrest 5 is rotated upward by the foot driving unit 6d. In this way, the control unit 8 controls the seat driving unit 6 to change the posture of the seat body. In other words, by making the seat body flat, the seated person can take a relaxed sitting posture (for example, a sleeping posture).

[0132] The posture of the seat main body changed by the seat driving unit 6 is not limited to this, and the posture of the seat main body may be changed according to the feelings of the seat occupant.

[0133] The control unit 8 controls the functional component 7 when the emotion index of the seated person estimated by the emotion estimation unit 31 is greater than the threshold value. Specifically, the control unit 8 controls the air conditioning unit 13 to emit fragrance toward the seated person when the emotion index of the seated person estimated by the emotion estimation unit 31 is greater than the threshold value. In addition, the control unit 8 controls the sound output unit 11 to output a sound related to the emotion index of the seated person when the emotion index of the seated person estimated by the emotion estimation unit 31 is greater than the threshold value. Furthermore, the control unit 8 controls the display unit 15 to display the emotion of the fellow passenger estimated by the emotion estimation unit 31.

[0134] When the control unit 8 determines that the emotion index calculated by the emotion estimation unit 31 is equal to or higher than a preset threshold, the control unit 8 emits a relaxing aroma toward the seated person via the air conditioning unit 13 .

[0135] Specifically, the air conditioning unit 13 emits the fragrance of the forest towards the seated person's face to relax the seated person. In addition, the control unit 8 also can control the air conditioning unit 13 to blow cold wind to the seated person and calm the excited state.

[0136] In addition, when the control unit 8 determines that the emotional index is above a preset threshold, the control unit 8 informs the seated person through the voice output unit 11 that the seated person is currently in an excited state. Specifically, the voice output unit 11 outputs a voice message "Since you are in an anxious excited state, please drive calmly." In addition, the voice output unit 11 outputs relaxing music or music that improves driving concentration. Furthermore, when it is estimated that the excited state is caused by poor posture, the voice output unit 11 outputs a voice message "Since your posture is poor, please correct your posture."

[0137] Furthermore, when the control unit 8 determines that the emotion index is equal to or greater than a preset threshold, the display unit 15 informs the seated person that the seated person or the fellow passenger is currently in an anxious state. Specifically, the display unit 15 displays a message "Since the fellow passenger is currently in an anxious state, please drive slowly." In addition, the display unit 15 displays an anxious face image or a smiling face image.

[0138] In addition, the functional components 7 controlled by the control unit 8 based on the seated occupant's emotional index estimated by the emotion estimation unit 31 are not limited to the sound output unit 11, the air conditioning unit 13, and the display unit 15. For example, when the seated occupant's emotional index estimated by the emotion estimation unit 31 is equal to or greater than a threshold value, the control unit 8 may control the movable unit 10 or the vibration unit 12 to massage the seated occupant to relax him. For example, when it is estimated that the excited state is caused by a poor posture, the movable unit 10 may be controlled to correct the seated occupant's posture.

[0139] In addition, the control unit 8 may measure the safe driving index (whether safe driving is being performed) based on the emotions of the seated person estimated by the emotion estimation unit 31. At this time, if there are fellow passengers, the safe driving index may be measured including the emotions of the fellow passengers estimated by the emotion estimation unit 31. For example, if the fellow passengers become anxious due to sudden braking, the safe driving index may be subtracted based on the anxious emotions, and the concern of dangerous driving may be notified through the sound output unit 11 or the display unit 15.

[0140] (Physical Condition Estimation Unit 32)

[0141] The physical condition estimation unit 32 estimates the physical conditions of the seated occupant and the fellow passenger based on the biological information acquired by the acquisition unit 30 .

[0142] Specifically, the physical condition estimation unit 32 estimates the physical condition of the seated person and the fellow passengers (heat stroke, feeling cold, unconsciousness, etc.) based on the biological information acquired by the acquisition unit 30. The physical condition estimation unit 32 uses a learning model constructed by machine learning to calculate a physical condition index based on the heart rate, body temperature, blood pressure, etc. as biological information, and estimates the physical condition of the seated person and the fellow passengers.

[0143] In addition, the parameters for calculating the physical condition index are not limited to heart rate, body temperature, and blood pressure. In addition, the physical condition of the seated person and the fellow passengers may be estimated based on the posture information acquired by the acquisition unit 30. For example, if the seated person does not exercise, it may be estimated that the physical condition is poor.

[0144] When the physical condition index of the seat occupant estimated by the physical condition estimating unit 32 is equal to or greater than a first threshold value, the control unit 8 controls the seat driving unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0145] Specifically, when the control unit 8 determines that the physical condition index calculated by the physical condition estimation unit 32 is equal to or higher than a preset first threshold value (for example, there is a concern about heat stroke), for example, the high link drive unit 6a raises the seat cushion 2, the reclining drive unit 6b tilts the seat back 1 backward, the tilting drive unit 6c raises the front part of the seat cushion 2, and the footrest 5 rotates upward through the foot drive unit 6d. In this way, the control unit 8 changes the posture of the seat body by controlling the seat drive unit 6, so that the seated person can take a relaxed sitting posture (for example, a sleeping posture).

[0146] The posture of the seat main body changed by the seat driving unit 6 is not limited to this, and the posture of the seat main body may be changed according to the physical condition of the seat occupant.

[0147] The control unit 8 controls the functional component 7 when the physical condition index of the seated person estimated by the physical condition estimation unit 32 is above the first threshold value. Specifically, the control unit 8 controls the air conditioning unit 13 to emit cold air or warm air toward the seated person when the physical condition index of the seated person estimated by the physical condition estimation unit 32 is above the first threshold value. In addition, the control unit 8 controls the notification unit 14 to make an emergency notification to the outside of the vehicle when the physical condition index of the seated person estimated by the physical condition estimation unit 32 is above the second threshold value higher than the first threshold value.

[0148] When the control unit 8 determines that the physical condition index calculated by the physical condition estimation unit 32 is equal to or higher than a preset first threshold value (for example, there is a concern about heat stroke), the air conditioning unit 13 blows cool air toward the neck of the seated person.

[0149] In addition, when the control unit 8 determines that the physical condition index calculated by the physical condition estimation unit 32 is above a pre-set second threshold value (for example, a state of severe heat stroke and unconsciousness), the control unit 8 automatically communicates with the emergency notification center through the notification unit 14 to make an emergency notification (a notification indicating that the seated occupant is unconscious, etc.).

[0150] Furthermore, the functional components 7 controlled by the control unit 8 based on the physical condition index of the seated occupant estimated by the physical condition estimation unit 32 are not limited to the air conditioning unit 13 and the notification unit 14. For example, when the physical condition index of the seated occupant estimated by the physical condition estimation unit 32 is equal to or greater than a threshold value, the control unit 8 may control the movable unit 10 or the vibration unit 12 to massage the seated occupant to relax him or her, or may control the sound output unit 11 or the display unit 15 to inform the seated occupant that the fellow passenger is in poor physical condition.

[0151] (Drinking estimation unit 33)

[0152] The drinking estimation unit 33 estimates the drinking degree of the seated person based on the position information and the biological information acquired by the acquisition unit 30 .

[0153] Specifically, the drinking estimation unit 33 estimates the drinking degree (drinking state, etc.) of the seated person based on the position information and biological information acquired by the acquisition unit 30. The drinking estimation unit 33 uses a learning model constructed by machine learning to calculate the drinking degree based on, for example, the position information (staying at a store that provides alcohol for a long time) and the heartbeat information (heart rate, pulse) or breathing rhythm as biological information, and estimates the drinking degree of the seated person.

[0154] The parameters for calculating the alcohol consumption are not limited to the position information, heart rate information, and breathing rhythm. In addition, the alcohol consumption of the seated person and the fellow passengers may be estimated based on the posture information acquired by the acquisition unit 30. For example, if the seated person's movements are not calmer than usual, it may be estimated that the person is in a state of drinking.

[0155] When the alcohol consumption of the seated occupant estimated by the alcohol consumption estimating unit 33 is equal to or greater than a threshold value, the control unit 8 controls the seat driving unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0156] Specifically, when the control unit 8 determines that the alcohol consumption calculated by the alcohol consumption estimation unit 33 is above a preset threshold value (e.g., a drinking state), for example, the high link driving unit 6a raises the seat cushion 2, the reclining driving unit 6b tilts the seat back 1 rearward, the tilt driving unit 6c raises the front part of the seat cushion 2, and the footrest 5 rotates upward through the foot driving unit 6d. In this way, the control unit 8 controls the seat driving unit 6 to change the posture of the seat body, so that the seated person can take a sitting posture that cannot drive (e.g., a sleeping posture).

[0157] When the drinking level of the seated person estimated by the drinking estimation unit 33 is equal to or higher than the threshold, the control unit 8 controls the functional component 7. Specifically, the control unit 8 controls the sound output unit 11 to output a sound related to the drinking level of the seated person.

[0158] When the control unit 8 determines that the physical condition index calculated by the drinking estimation unit 33 is equal to or higher than a preset threshold value (eg, the person is in a drinking state), the sound output unit 11 outputs a message “Please do not drive as you are in a drinking state”.

[0159] Furthermore, the functional component 7 that the control unit 8 controls based on the alcohol consumption of the seated person estimated by the alcohol consumption estimating unit 33 is not limited to the sound output unit 11 .

[0160] Furthermore, the control unit 8 determines the drinking degree of the fellow passenger through the drinking estimation unit 33 and may control the seat drive unit 6 or the functional component 7 when the fellow passenger is in a drinking state.

[0161] (Posture Estimation Unit 34)

[0162] The posture estimation unit 34 estimates the seating posture of the seated person based on the posture information acquired by the acquisition unit 30 .

[0163] Specifically, the posture estimation unit 34 estimates the seating posture based on the posture information acquired by the acquisition unit 30. The posture estimation unit 34 estimates that the seating posture of the seated person is the same for a predetermined time based on the posture information, for example, using a learning model constructed by machine learning.

[0164] When the posture estimating unit 34 estimates that the seated posture of the seated occupant has remained the same for a predetermined period of time, the control unit 8 controls the seat driving unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0165] Specifically, when the posture estimation unit 34 determines that the seated posture remains the same for a predetermined time, the control unit 8 drives, for example, the high link drive unit 6a, the reclining drive unit 6b, the tilting drive unit 6c, and the foot drive unit 6d to move the seat back 1, the seat cushion 2, and the footrest 5. In this way, the control unit 8 controls the seat drive unit 6 to change the posture of the seat body, thereby improving blood flow by moving the body of the seated person, thereby preventing traveler's thrombosis.

[0166] When the posture estimating unit 34 estimates that the seated posture of the seated person remains the same for a predetermined time, the control unit 8 controls the functional member 7. Specifically, the control unit 8 controls the movable unit 10 to shake or knead the body of the seated person.

[0167] When the posture estimating unit 34 determines that the seated posture has remained the same for a predetermined period of time, the control unit 8 expands and contracts the air chamber of the movable unit 10 to massage the seated person.

[0168] Furthermore, the functional component 7 controlled by the control unit 8 based on the seated posture of the seated person estimated by the posture estimating unit 34 is not limited to the movable unit 10 .

[0169] (Blood Pressure Estimation Unit 35)

[0170] The blood pressure estimation unit 35 estimates the sitting posture of the seated person based on the biological information acquired by the acquisition unit 30 .

[0171] Specifically, the blood pressure estimation unit 35 estimates the seated posture based on the biological information (blood pressure or water content) acquired by the acquisition unit 30. The blood pressure estimation unit 35 estimates the blood pressure index of the seated person based on, for example, blood pressure or water content, using a learning model constructed by machine learning.

[0172] When the blood pressure index of the seated occupant estimated by the blood pressure estimating unit 35 is equal to or higher than a threshold value (high blood pressure and insufficient water content), the control unit 8 controls the seat driving unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0173] Specifically, when the control unit 8 determines that the blood pressure index calculated by the blood pressure estimation unit 35 is equal to or higher than a preset threshold value, the control unit 8 drives, for example, the high link drive unit 6a, the reclining drive unit 6b, the tilting drive unit 6c, and the foot drive unit 6d to move the seat back 1, the seat cushion 2, and the footrest 5. In this way, the control unit 8 controls the seat drive unit 6 to change the posture of the seat body, thereby improving blood flow by moving the body of the seated person, thereby preventing traveler's thrombosis.

[0174] When the control unit 8 estimates that the blood pressure index calculated by the blood pressure estimation unit 35 is equal to or greater than a preset threshold value, the control unit 8 controls the functional component 7. Specifically, the control unit 8 controls the movable unit 10 to shake or knead the body of the seated person.

[0175] When the control unit 8 determines that the blood pressure index calculated by the blood pressure estimation unit 35 is equal to or higher than a preset threshold value (for example, a state of high blood pressure and insufficient water content), the control unit 8 expands and contracts the air chamber of the movable unit 10 to massage the seated person.

[0176] Furthermore, the functional component 7 that the control unit 8 controls based on the seated posture of the seated person estimated by the blood pressure estimating unit 35 is not limited to the movable unit 10 .

[0177] (Fatigue Estimation Unit 36)

[0178] The fatigue estimating unit 36 ​​estimates the fatigue level of the seated person based on the biological information acquired by the acquiring unit 30 .

[0179] Specifically, the fatigue estimating unit 36 ​​estimates the fatigue level based on the biological information (blood oxygen concentration) acquired by the acquiring unit 30. The fatigue estimating unit 36 ​​estimates the fatigue level of the seated person based on, for example, the blood oxygen concentration, using a learning model constructed by machine learning.

[0180] When the fatigue level of the seat occupant estimated by the fatigue estimating unit 36 ​​is equal to or higher than a threshold value (fatigue state with low blood oxygen concentration), the control unit 8 controls the seat driving unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0181] Specifically, when the control unit 8 determines that the fatigue level calculated by the fatigue estimation unit 36 ​​is equal to or higher than a preset threshold, for example, the control unit 8 raises the seat cushion 2 through the high link drive unit 6a, tilts the seat back 1 rearward through the reclining drive unit 6b, raises the front portion of the seat cushion 2 through the tilting drive unit 6c, and rotates the footrest 5 upward through the foot drive unit 6d. In this way, the control unit 8 changes the posture of the seat body by controlling the seat drive unit 6, so that the seated person can take a relaxed sitting posture (for example, a sleeping posture).

[0182] When the control unit 8 estimates that the fatigue level calculated by the fatigue estimation unit 36 ​​is equal to or greater than a preset threshold, the control unit 8 controls the functional member 7. Specifically, the control unit 8 controls the movable unit 10 to shake or knead the body of the seated person.

[0184] Furthermore, the functional component 7 that the control unit 8 controls based on the degree of fatigue estimated by the fatigue estimating unit 36 ​​is not limited to the movable unit 10 .

[0185] (Sleepiness Estimation Unit 37)

[0186] The sleepiness estimation unit 37 estimates the sleepiness level of the seated person based on the biological information acquired by the acquisition unit 30 .

[0187] Specifically, the sleepiness estimation unit 37 estimates the sleepiness level of the occupant based on the biological information (heart rate, breathing depth, blood pressure) and the time since waking up acquired by the acquisition unit 30. The sleepiness estimation unit 37 estimates the sleepiness level of the occupant based on, for example, the heart rate, breathing depth, blood pressure, etc. and the time since waking up, using a learning model constructed by machine learning.

[0188] When the occupant's sleepiness level estimated by the sleepiness estimation unit 37 is equal to or higher than a threshold value (awake state, asleep state), the control unit 8 controls the seat drive unit 6 to change the postures of the seat back 1 and the seat cushion 2 .

[0189] Specifically, when the control unit 8 determines that the sleepiness level calculated by the sleepiness estimation unit 37 is equal to or higher than a preset threshold value, the control unit 8 drives, for example, the high link drive unit 6a, the reclining drive unit 6b, the tilting drive unit 6c, and the foot drive unit 6d to move the seat back 1, the seat cushion 2, and the footrest 5. In this way, the control unit 8 controls the seat drive unit 6 to change the posture of the seat body, thereby causing the seat occupant to move his body and thus urge the seat occupant to wake up.

[0190] When the control unit 8 estimates that the sleepiness level calculated by the sleepiness estimation unit 37 is equal to or higher than a preset threshold, the control unit 8 controls the functional component 7. Specifically, the control unit 8 controls the air conditioning unit 13 to release cool air toward the seated person.

[0191] When the control unit 8 determines that the sleepiness level calculated by the sleepiness estimation unit 37 is equal to or higher than a preset threshold value (for example, the occupant is awake), the air conditioning unit 13 blows cool air toward the neck of the seated person.

[0192] In addition, the functional component 7 controlled by the control unit 8 based on the sleepiness level estimated by the sleepiness estimation unit 37 is not limited to the air conditioning unit 13. For example, the vibration unit 12 may be used to stimulate the seated person to wake up. In addition, the control unit 8 may control the sound output unit 11 or the display unit 15 to inform the seated person that it is time to get up.

[0193] In this way, the states of the seated occupants and fellow passengers can be determined by the emotion estimation unit 31 , the physical condition estimation unit 32 , the drinking estimation unit 33 , the posture estimation unit 34 , the blood pressure estimation unit 35 , the fatigue estimation unit 36 ​​, and the sleepiness estimation unit 37 .

[0194] Furthermore, the states of the seated occupants and fellow passengers may be determined in a complex manner based on the information estimated by the various estimating units.

[0195] <<Regarding the control of vehicle seats>>

[0196] Next, the flow of the control process of the vehicle seat S executed by the control unit 8 will be described. Figure 3 As shown, the control process of the vehicle seat S is performed to drive the vehicle seat S when the seat occupant is seated in the seat body. Specifically, the control unit 8 performs the following processes: biological information acquisition processing for acquiring biological information from the wearable device W (step S10), posture information acquisition processing for acquiring posture information from the wearable device W (step S20), position information acquisition processing for acquiring position information from the wearable device W (step S30), and seat control processing for driving the vehicle seat S (step S40).

[0197] In the biological information acquisition process (step S10 ), the biological information of the seated person and the fellow passenger detected by the biological sensor 20 of the wearable device W is acquired by the acquisition unit 30 .

[0198] In the posture information acquisition process (step S20 ), the posture information of the seated person and the fellow passenger detected by the position detection unit 21 of the wearable device W is acquired by the acquisition unit 30 .

[0199] In the position information acquisition process (step S30 ), the position information of the seated person and the fellow passenger detected by the posture detection unit 22 of the wearable device W is acquired by the acquisition unit 30 .

[0200] In addition, the control unit 8 acquires biological information, posture information, and position information from the wearable device W in real time.

[0201] Next, use Figure 4 The seat control process (step S40 ) will be described.

[0202] After the acquisition unit 30 acquires biological information, posture information and position information, the control unit 8 estimates the state of the seated person and the fellow passenger (step S41) through the emotion estimation unit 31, the physical condition estimation unit 32, the drinking estimation unit 33, the posture estimation unit 34, the blood pressure estimation unit 35, the fatigue estimation unit 36 ​​and the sleepiness estimation unit 37 based on the biological information, posture information and position information. Then, the state of the seated person and the fellow passenger (step S41) is determined, and the seat drive unit 6 is controlled (step S43) according to the state of the seated person and the fellow passenger. And then, the functional component 7 is controlled (step S44) according to the state of the seated person and the fellow passenger. The control unit 8 estimates the state of the seated person and the fellow passenger in real time based on the biological information, posture information and position information obtained from the wearable device W, thereby continuously determining the state of the seated person and the fellow passenger.

[0203] When determining the status of the seated occupant and the passenger, the control unit 8 may drive only the seat drive unit 6 or may drive only the functional component 7.

[0204] Next, use Figure 5 The seat drive unit control process (step S43) will be described. In this description, an example in which the seat drive unit 6 is controlled based on the emotion index estimated by the emotion estimation unit 31 will be described.

[0205] The control unit 8 obtains the state of the seated person or the fellow passenger estimated by the emotion estimation unit 31 (step S43-1). When the emotion index is above the threshold value and the person is in an excited state (step S43-2: Yes), the control unit 8 controls the seat drive unit 6 to change the posture of the seat body (step S43-3). Specifically, the control unit 8 changes the posture of the seat back 1, the seat cushion 2, and the footrest 5 so that the seat body is in a flat posture. In addition, when the person is not in an excited state (step S43-2: No), the control unit 8 returns the seat body to the initial posture (step S43-4) and ends the processing.

[0206] In this way, the control unit 8 changes the posture of the seat body so that the emotional index is less than the threshold value and the state is not excited (in other words, it is a relaxed state).

[0207] Next, use Figure 6 The functional component control process (step S44) will be described. In this description, an example in which the movable portion 10 of the functional component 7 is controlled based on the fatigue degree estimated by the fatigue estimating unit 36 ​​will be described.

[0208] The control unit 8 obtains the state of the seated person or the fellow passenger estimated by the fatigue estimation unit 36 ​​(step S44-1). When the fatigue degree is above the threshold and is in a fatigue state (step S44-2: yes), the control unit 8 controls the movable part 10 of the functional component 7 to shake and knead the body of the seated person (step S43-3). Specifically, the control unit 8 causes the air chamber of the movable part 10 to expand and contract to massage the seated person. In addition, the control unit 8 ends the processing when it is not in a fatigue state (step S44-2: no). In addition, the control unit 8 continuously determines the state of the seated person based on the biological information obtained from the wearable device W, thereby changing the intensity of the kneading program in real time.

[0209] In this way, the control unit 8 massages the seat body until the fatigue level is less than the threshold value and the seat is not in a fatigue state. In addition, the control unit 8 may also control to prohibit the vehicle from running when the massage is in progress. In this case, the control unit 8 may also control to allow the vehicle to run when the massage is finished and it is determined that the seat is not in a fatigue state.

[0210] According to the above structure, the seat drive unit 6 and the functional component 7 can be controlled based on the biological information, posture information and position information obtained from the wearable device W. Therefore, the vehicle seat S can be controlled according to the state of the seated person or the fellow passenger, so that the comfort and convenience of the seated person and the fellow passenger can be improved.

[0211] In particular, in the seat system S1 of the present embodiment, the control unit 8 controls both the seat drive unit 6 and the functional component 7 according to the state of the seated person or the passenger. The control unit 8 changes the posture of the seat body through the seat drive unit 6 according to the state of the seated person or the passenger, and controls the functional component 7 at the same time, so that the comfort and convenience of the seated person can be further improved compared to when only the functional component 7 is driven.

[0212] In addition, the control unit 8 can acquire biological information, posture information, and position information acquired from the wearable device W in real time, and control the seat drive unit 6 and the functional component 7 in real time according to the status of the seated person or the passenger.

[0213] <Second embodiment>

[0214] Below, refer to Figure 7 to Figure 9 A seat system S2 according to a second embodiment of the present invention will be described.

[0215] The seat system S2 can change the position of a display operated by an occupant. In addition, description of the configuration that overlaps with that of the seat system S1 will be omitted.

[0218] The display 107 includes a meter display 107a, a navigation display 107b, and an air conditioning display 107c.

[0219] The meter display monitor 107a, the navigation display monitor 107b, and the air conditioning display monitor 107c are detachably mounted on the instrument panel 103. The monitor 107 can be removed from the instrument panel 103 and mounted at a mounting position (P1 to P5) provided inside the vehicle 100.

[0220] Specifically, the first mounting position P1 is set on the upper surface of the console box 104. The second mounting position P2 is set on the back of the front seat 101. The third mounting position P3 is set on the armrest of the rear seat 102. The fourth mounting position P4 is set on the front side pillar 105. The fifth mounting position P5 is set on the rear side pillar 106.

[0221] When the vehicle 100 is traveling, the display 107 is provided on the instrument panel portion 103 and is arranged at a position where the occupant sitting on the front seat 101 can operate it.

[0234] The reclining device 111 e is a device that connects the seat back 111 a to the seat cushion 111 b in a rotatable manner and can lock the seat back 111 a .

[0235] The reclining device 111e is configured to return to the locked state when the occupant tilts the seat back 111a rearward while the seat back 111a is in the unlocked state and releases the reclining operation lever when the rearward tilting angle reaches a desired angle.

[0236] The leg device 111f is a device that connects the ottoman 111d to the seat cushion 111b so as to be rotatable and can lock the ottoman 111d.

[0237] The foot device 111f is configured such that when the occupant rotates the ottoman 111d upward while the ottoman 111d is in the unlocked state, the ottoman 111d is restored to the locked state when the occupant releases the reclining operation lever at the time when the rotation angle reaches a desired angle.

[0238] The seat back 111a and the footrest 111d are moved from the normal position ( Fig. 10A ) is rotated to a horizontal position relative to the seat cushion 111b ( Fig. 10B ). As a result, the occupant can take a relaxed posture on the seat body, thereby resting the body.

[0239] Generally, in an SUV, the rear seat 111 is arranged one level higher than the lower level of the floor 112 by means of a battery storage space, etc. Therefore, the vehicle 110 can use the step difference of the floor 112 to set the rear seat 111 as a flat seat.

[0240] <Fourth embodiment>

[0241] Below, refer to Figure 11 to Figure 13 A seat system S4 according to a fourth embodiment of the present invention will be described.

[0242] The seat system S4 can change the position of a display device operated by an occupant. In addition, description of the configurations that overlap with those of the seat system S1 , the seat system S2 , and the seat system S3 will be omitted.

[0243] like Fig.11 As shown, the seat system S4 includes a display device 120 operated by the occupant. The display device 120 includes a display unit 121 operated by the occupant and a holding unit 122 for holding the display unit 121. The display device 120 is provided in the dashboard of an SUV, for example, and can display the status of instruments or the vehicle.

[0244] The display unit 121 is a touch panel display device and is a tablet terminal that can be removed from the holding unit 122 and used. The display unit 121 displays instruments during driving. In addition, the display unit 121 becomes an operation panel that can operate functional units (such as air conditioning and navigation) provided in the vehicle.

[0245] The holding unit 122 is provided inside the vehicle, and includes a housing portion 122 a for housing the display unit 121 and a state display unit 122 b for displaying the state of the vehicle.

[0246] The housing portion 122a is a recessed portion formed on the upper surface of the holding portion 122. The display unit 121 is detachably provided in the housing portion 122a.

[0247] The state display unit 122 b is provided on the front surface of the holding unit 122 , and informs the state of the vehicle through a light emitting diode (LED) or the like.

[0248] The state display unit 122b displays the vehicle state in a visually recognizable manner when in the warning on mode for displaying the vehicle state. In addition, the state display unit 122b cannot visually recognize the vehicle state when in the warning off mode for not displaying the vehicle state.

[0249] In addition, as a method of making the vehicle state invisible, turning off the LED and making it invisible using a light-transmitting film are mentioned.

[0250] like Fig.11 As shown, in the warning on mode, when the display unit 121 is accommodated in the accommodating portion 122a of the retaining portion 122, the instrument is displayed on the screen of the display unit 121. At this time, the state display unit 122b informs the occupant of the state of the vehicle through an LED or the like. Specifically, the state display unit 122b lights up an image of a warning or notification information. In addition, the state display unit 122b lights up an image indicating the charging state of the vehicle battery or the fullness state of gasoline. Furthermore, the state display unit 122b lights up an image indicating the driving state such as the speed or the turn signal.

[0251] like Fig.12 As shown, in the warning off mode, when the display unit 121 is stored in the storage unit 122a of the holding unit 122, the meter is displayed on the screen of the display unit 121. At this time, the state display unit 122b turns off the image indicating the state of the vehicle so that it cannot be visually recognized.

[0252] like Fig.13 As shown, in the warning on mode, when the display unit 121 is not accommodated in the accommodation portion 122 a of the holding portion 122 , the state display unit 122 b informs the occupant of the state of the vehicle through an LED or the like.

[0253] Thus, when the vehicle is parked, the display unit 121 showing the instrument can be used as an operation panel, so the vehicle feel can be reduced by not having an instrument. Therefore, the vehicle compartment can be made to look like a room at home, thus expanding the range of vehicle compartment usage during parking.

[0254] In addition, the status display unit 122b is mainly information required for driving, so it is configured at a position independent of the detachable display unit 121. By setting the warning off mode during parking, the status display unit 122b can be made to look non-existent, so the car feeling can be further reduced.

[0255] <Fifth Embodiment>

[0256] Below, refer to Figures 14 to 18B A seat system S5 according to a fifth embodiment of the present invention will be described.

[0257] The seat system S5 can change the shape of the seat body. In addition, the description of the structure that overlaps with the seat system S1, the seat system S2, the seat system S3, and the seat system S4 is omitted.

[0258] like Fig.14As shown, the seat system S5 includes: a seat body having a seat back 130 and a headrest 131; and a seat movable portion 132, which moves a portion of the seat body between a normal position and a protruding position protruding toward the passenger side more than the normal position. The seat back 130 has a back center portion 130a that supports the passenger from the rear and a bank-shaped portion 130b that supports the passenger from the side.

[0259] The seat movable portion 132 is provided inside the seat back 1 and serves as a pillow for the occupant when the occupant takes a sleeping position. The seat movable portion 132 is, for example, an air chamber that moves so that both end portions 133 of the back center portion 130a of the seat back 130 protrude forward.

[0260] Furthermore, the seat movable portion 132 may be configured to operate via a mechanical mechanism (a link mechanism, a hinge mechanism, or the like).

[0261] When the seat back 130 is tilted backward by a reclining device (not shown), the seat movable portion 132 causes both end portions 133 of the back center portion 130a to move from a normal position ( Fig.15A ) to the protruding position ( Fig. 15B Furthermore, the two end portions 133 of the backrest center portion 130a become pillow portions for supporting the head of the occupant through the seat movable portion 132.

[0262] Next, Fig.16 The seat movable portion 132A of Modification 1 shown will be described. The seat movable portion 132A is, for example, an air chamber that operates so that a central portion 133A of a backrest central portion 130a of a seat back 130 projects forward.

[0263] When the seat back 130 is tilted rearward by a reclining device (not shown), the seat movable portion 132A causes the central portion 133A of the back center portion 130a to move from the normal position ( Fig.17A ) to the protruding position ( Fig. 17B ) moves. Moreover, the central portion 133A of the backrest central portion 130a becomes a pillow portion for supporting the head of the occupant through the seat movable portion 132A.

[0264] Then, Fig.18A , Fig.18B The seat movable portion 132B of Modification 2 shown in the figure will be described. The seat movable portion 132B is, for example, a pressing mechanism that operates so that a cushion portion 133B in the backrest center portion 130a of the seat back 130 protrudes forward.

[0265] The cushion portion 133B is a cushion portion formed of a material softer than the surface of the seat back 130. In addition, the seat movable portion 132B is not limited to a pressing mechanism, and may be configured so that the cushion portion 133B swells by sending air. The cushion portion 133B is formed of a material softer than the surface, so it is easy to expand. Therefore, the force that causes the cushion portion 133B to protrude forward can be reduced.

[0266] When the seat back 130 is tilted backward by a reclining device (not shown), the seat movable portion 132B causes the cushion portion 133B of the back center portion 130a to move from the normal position ( Fig.18A ) to the protruding position ( Fig.18B ) moves. Moreover, the cushion portion 133B of the backrest center portion 130a becomes a pillow portion for supporting the head of the occupant through the seat movable portion 132B.

[0267] Thus, when the seat back 130 is tilted backward, the passenger can use the two end portions 133 of the back center portion 130a protruding through the seat movable portion 132 as pillows, so that it is easy to take a sleeping posture. In addition, in the sleeping posture, since the passenger's head is fixed by the two end portions 133, it is easy for the passenger to operate the smartphone in the sleeping posture.

[0268] Furthermore, since the seat movable portion 132 is provided on the seat back 130, it is easier to support the head of the occupant when the seat back 130 is tilted backward, compared with the case where the seat movable portion 132 is provided on the headrest 131. In addition, when the seat movable portion 132 is set as an electric type and wiring is required, the degree of freedom of wiring layout can be improved.

[0269] <Sixth embodiment>

[0270] Below, refer to Figures 19A to 19C A seat system S6 according to a sixth embodiment of the present invention will be described.

[0271] The seat system S6 can change the position of the armrest of the seat body. In addition, the description of the structure overlapped with the seat system S1, the seat system S2, the seat system S3, the seat system S4, and the seat system S5 is omitted.

[0272] like Fig.19A As shown, the seat system S6 includes a seat body having a seat back 140 , a seat cushion 141 , a headrest 142 , and an elbow rest 143 .

[0273] The armrest 143 is a simple armrest mounted on both sides of the seat back 140 to support the elbows of the occupant. The armrest 143 can be rotatably mounted on the seat back 140 and can be in the storage state ( Fig.19A )、First use state ( Fig.19B ) and the second use state ( Fig.19C The occupant can adjust the height position of the armrest 143 by switching the armrest 143 from the storage state to the first use state or the second use state.

[0274] like Fig.19A As shown, the armrest 143 in the stowed state is arranged at a position overlapping the seat back 140 when viewed from the side. Specifically, the first end 143a which is the upper end of the armrest 143 in the stowed state and the second end 143b which is the lower end of the armrest 143 in the stowed state are arranged at a position overlapping the seat back 140 when viewed from the side.

[0275] When the occupant is not using the armrest 143 , the occupant can store the armrest 143 in the seat back 140 by rotating the armrest 143 relative to the seat back 140 .

[0276] like Fig.19B As shown, the armrest 143 in the first use state is arranged horizontally at the center of the seat back 140 in the vertical direction. Specifically, the armrest 143 is rotated backward from the storage state, and arranged with the first end 143a of the armrest 143 at the rear and the second end 143b at the front.

[0277] When the occupant uses the armrest 143, the occupant can unfold the armrest 143 and use the armrest 143 by rotating the armrest 143 relative to the seat back 140. The length of the armrest 143 is formed short enough to fix the elbow of the occupant.

[0278] like Fig.19C As shown, the armrest 143 in the second use state is arranged horizontally at a lower position in the vertical direction of the seat back 140. Specifically, the armrest 143 is rotated 180 degrees from the first use state, and is arranged with the first end 143a of the armrest 143 facing forward and the second end 143b facing backward.

[0279] When the occupant wants to change the height of the armrest 143 , the occupant can adjust the height position of the armrest 143 by rotating the armrest 143 relative to the seat back 140 .

[0280] The armrest 143 can only rotate clockwise ( Fig.19B The armrest 143 is rotated in one direction (direction A in the figure), and rotation restriction is performed by applying locking to counterclockwise rotation. In this way, the strength of the armrest 143 can be improved by performing rotation restriction.

[0281] Thus, the armrest 143 can be changed to two levels of height by shortening the length of the armrest 143 and arranging it to be rotatable relative to the seat back 140. Therefore, the height of the armrest 143 can be adjusted according to the physique of the passenger.

[0282] <Seventh embodiment>

[0283] Below, refer to Figures 20A to 21B A seat system S7 according to a seventh embodiment of the present invention will be described.
