Description

[Technical Field]

[0001] The present invention relates to a vehicle interior system including an ornament and a control unit. [Background technology]

[0002] Conventionally, a vehicle interior system equipped with a plush toy-like three-dimensional notification object placed on the dashboard of a vehicle has been known (see Patent Document 1). The three-dimensional notification object notifies the occupants of various traffic information (vehicle route, driving status, etc.) through gestures, mannerisms, facial expressions, flashing lights, etc., and entertains the occupants by having conversations with them.

[0003] Also known as a vehicle interior system is one that includes an agent device installed on the dashboard of the vehicle (see Patent Document 2). The agent device is a small robot that communicates with the occupant through voice and movement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-104103 [Patent Document 2] Japanese Patent Application Publication No. 2024-73110 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in conventional technology, information is communicated to occupants through the movements and sounds of a robot on the dashboard, so there is a risk that occupants may not notice the robot's actions if they take their eyes off the robot or if there is a lot of noise outside the vehicle.

[0006] Furthermore, since the crew can only communicate with the robot through sight and hearing, there was a need to improve the quality of communication and entertainment value.

[0007] Therefore, an object of the present invention is to make it easier for passengers to notice the actions of decorative objects such as robots. [Means for solving the problem]

[0008] In order to solve the above problem, the vehicle interior system according to the present invention includes a decorative item and a control unit. The ornament is provided in an interior member of a vehicle and has a movable body that is moved by an actuator. The movable body is movable between a spaced position away from an occupant seated on the seat and a contact position capable of coming into contact with the occupant seated on the seat. The control unit controls the actuator to move the movable body from the separated position toward the contact position, thereby executing a contact process to bring the movable body into contact with the occupant.

[0009] By configuring the control unit to perform a contact process that moves the movable body of the ornament and brings the movable body into contact with the occupant, the action of the ornament can be made known to the occupant through touch, making it easier for the occupant to notice the action of the ornament.

[0010] The vehicle interior system may further include a contact sensor that detects contact of the movable body with an occupant. In the contact processing, the control unit may move the movable body until it is determined that the movable body has come into contact with the occupant, based on information acquired by the contact sensor.

[0011] By configuring the movable body to move until the control unit determines that the movable body has come into contact with the occupant based on information from the contact sensor, the movable body can be reliably brought into contact with the occupant.

[0012] The contact sensor may also be a pressure sensor. The control unit may change the strength of the pressure applied from the movable body to the occupant in the contact process based on the pressure value acquired by the pressure sensor.

[0013] By configuring the strength of the pressure applied to the occupant from the movable body to be changeable, it is possible to increase the variety of communication and notifications.

[0014] The vehicle interior system may also include a voice acquisition unit that acquires the voice of the occupant, and the control unit may change the movement of the movable body based on the voice acquired by the voice acquisition unit.

[0015] By configuring the movement of the movable body to change based on voice, it is possible to increase the variety of communication and notifications.

[0016] The control unit may also control the actuator so that the pressure applied from the movable body to the occupant increases as the volume of the sound acquired by the sound acquisition unit increases.

[0017] The decorative item may also protrude from the outer surface of the interior member.

[0018] The interior member may be a seat, and the decorative item may be located on top of the seat.

[0019] The seat may have a seating surface that supports an occupant, and the decorative item may protrude from an outer surface other than the seating surface.

[0020] Furthermore, the control unit may prohibit the contact process when a vehicle collision is predicted.

[0021] If the control unit predicts a vehicle collision, the control unit can prohibit the contact process, thereby improving safety.

[0022] The seat may also include an electric device that moves at least a portion of the seat, and the control unit may operate the electric device when moving the movable body.

[0023] By configuring the seat's electric device to operate when the movable body moves, it is possible to increase the variety of communication and notifications. [Effects of the Invention]

[0024] According to the present invention, the control unit executes a contact process in which the movable body of the ornament moves and brings the movable body into contact with the occupant, thereby allowing the occupant to recognize the action of the ornament through touch, thereby making it easier for the occupant to notice the action of the ornament.

[0025] Furthermore, by configuring the movable body to move until the control unit determines that the movable body has come into contact with the occupant based on information from the contact sensor, the movable body can be reliably brought into contact with the occupant.

[0026] Furthermore, by configuring the strength of the pressure applied to the occupant from the movable body to be changeable, it is possible to increase the variety of communication and notifications.

[0027] Furthermore, by configuring the movement of the movable body to change based on voice, it is possible to increase the variety of communication and notifications.

[0028] Furthermore, safety can be improved by configuring the control unit to prohibit contact processing when it predicts a vehicle collision.

[0029] In addition, by configuring the seat's electric device to operate when the movable body moves, it is possible to increase the variety of communication and notifications. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0031] [First embodiment] Hereinafter, a first embodiment of a vehicle interior system will be described with reference to the accompanying drawings. As shown in Fig. 1, the vehicle interior system 1 includes a seat 10 as an example of an interior member, a camera C, a tail member 20 as an example of a decorative item, and a control unit 100. The seat 10, the camera C, and the tail member 20 are arranged inside the vehicle, more specifically, in positions facing the passenger compartment. In this embodiment, the seat 10 is the driver's seat or the passenger seat.

[0032] The seat 10 includes a seat cushion 11, a seat back 12, and a headrest 13. The seat cushion 11, the seat back 12, and the headrest 13 each constitute a seat body having a seating surface F. The seating surface F is a surface that comes into contact with and supports an occupant (e.g., a driver) seated in the seat 10.

[0033] The seat cushion 11, seat back 12, and headrest 13 each have a metal frame that forms the framework, a pad that covers the frame, and a skin that covers the pad. The pad is made of urethane foam or the like. The skin is made of synthetic leather, fabric, or the like.

[0034] The seat cushion 11 has a base portion 11A located in the left-right center and protruding portions 11B located on both the left and right outer sides of the base portion 11A. The base portion 11A has a seating surface F that contacts and supports the buttocks and thighs of the occupant from below. The protruding portions 11B protrude from the seating surface F of the base portion 11A toward the occupant to support the sides of the occupant's thighs and buttocks.

[0035] Similarly, the seat back 12 has a base portion 12A located in the center of the seat back and extension portions 12B located on both the left and right sides of the base portion 12A. The base portion 12A has a seating surface F that contacts the back of the occupant and supports the back from behind. The extension portions 12B extend from the seating surface F of the base portion 12A toward the occupant to support the sides of the occupant's upper body.

[0036] The front surface of the headrest 13 serves as a seating surface F that supports the head of the occupant.

[0037] The camera C is a camera that captures an image in front of the vehicle. The camera C is installed, for example, on the ceiling of the vehicle. Image information captured by the camera C is output to the control unit 100.

[0038] The tail member 20 is provided on the upper part of the seat 10. More specifically, the tail member 20 is located on the left side surface FL of the headrest 13. The side surface FL is the outer surface of the headrest 13 other than the seating surface F. The tail member 20 protrudes from the side surface FL.

[0039] The tail member 20 has a base portion 21 and a movable body 22. The base portion 21 is a portion that is fixed to the headrest 13. The base portion 21 is, for example, embedded in the pad of the headrest 13 and fixed to the frame of the headrest 13.

[0040] The movable body 22 extends from the base 21, and its tip is configured to be able to move freely in all directions. The movable body 22 is shaped, for example, to resemble a cat's tail. The movable body 22 has, for example, a joint mechanism with multiple joints, a cushioning material such as cotton or sponge that covers the joint mechanism, and a surface covering that covers the cushioning material. The surface is made of, for example, cloth or brushed fabric.

[0041] The joint mechanism has a plurality of links (serial links) that are rotatably connected to each other, and the plurality of links are moved by an actuator.

[0042] The joint mechanism can be configured, for example, like a robot arm. In this case, the actuators for moving the multiple links are multiple motors arranged near the multiple joints.

[0043] The joint mechanism can also be configured to include, for example, multiple links, a spring that biases the multiple links so that they are aligned in a straight rod shape, a wire that pulls the distal link in a direction that causes the multiple links to fold against the biasing force of the spring, and a winch for pulling the wire. In this case, the actuator for moving the multiple links is a winch, and when the winch pulls the wire, the joint mechanism moves in a direction that causes the joint mechanism to fold, and when the winch releases the wire, the spring moves the joint mechanism in a direction that causes the joint mechanism to extend straight. In this case, using multiple wires allows the joint mechanism to be moved so as to fold in different directions, and the distal end of the movable body 22 can be freely moved in any direction.

[0044] The movable body 22 protrudes from the side surface FL. The movable body 22 has a contact sensor 22A at its tip that detects contact of the movable body 22 with an occupant. The contact sensor 22A may be, for example, a capacitance type touch sensor or a pressure sensor. The contact sensor 22A is located, for example, between the surface and the cushioning material.

[0045] The movable body 22 is movable between a separated position shown in Fig. 2(a) and a contact position shown in Fig. 2(b) and (c). The movable body 22 positioned at the separated position is separated from the occupant seated in the seat 10. The movable body 22 positioned at the contact position is capable of coming into contact with the occupant seated in the seat 10.

[0046] The control unit 100 has a CPU, ROM, RAM, rewritable non-volatile memory, etc. (not shown), and executes pre-stored programs. The control unit 100 may be provided in the seat 10, or may be provided in a member other than the seat 10.

[0047] The control unit 100 has a function of executing a contact process in which the movable body 22 contacts the occupant by controlling the actuator of the tail member 20 to move the movable body 22 from the separated position toward the contact position. In the contact process, the control unit 100 moves the movable body 22 until it determines that the movable body 22 has contacted the occupant based on information acquired by the contact sensor 22A.

[0048] Furthermore, the control unit 100 has a function of prohibiting contact processing when a vehicle collision is predicted. Specifically, the control unit 100 determines whether or not there is a possibility that the vehicle will collide with an object ahead based on image information acquired from the camera C, and prohibits contact processing when it determines that there is a possibility of a collision.

[0049] Next, a detailed description will be given of the operation of the control unit 100. While the vehicle power supply is ON, the control unit 100 repeatedly executes the contact process shown in Fig. 3 and the prohibition process shown in Fig. 4 in parallel.

[0050] When the vehicle power supply is turned on, the control unit 100 starts counting up using a timer and executes the contact processing shown in FIG.

[0051] In the contact process, the control unit 100 first determines whether the timer value is equal to or greater than the threshold value (S1). If it is determined in step S1 that the timer value is not equal to or greater than the threshold value (No), the control unit 100 ends this process.

[0052] If it is determined in step S1 that the timer value is equal to or greater than the threshold value (Yes), the control unit 100 moves the tip of the tail member 20 toward the contact position (S2). After step S2, the control unit 100 determines whether the tip of the tail member 20 has touched the occupant based on information from the contact sensor 22A (S3).

[0053] If it is determined in step S3 that the tip of the tail member 20 is not touching the occupant (No), the control unit 100 repeats the process of step S3 (No). If it is determined in step S3 that the tip of the tail member 20 is touching the occupant (Yes), the control unit 100 returns the tip of the tail member 20 to the separated position (S4). Note that if the condition of step S3 is not met even after a predetermined time has elapsed in step S3, the control unit 100 proceeds to the process of step S4 and returns the tip of the tail member 20 to the separated position.

[0054] After step S4, the control unit 100 resets the timer and causes the timer to count up again (S5). After step S5, the control unit 100 ends this process.

[0055] 4, the control unit 100 first determines whether or not there is a possibility of a collision based on image information acquired from the camera C (S21). If it is determined in step S21 that there is no possibility of a collision (No), the control unit 100 ends this process.

[0056] If it is determined in step S21 that there is a possibility of a collision (Yes), the control unit 100 prohibits the contact process (S22) and ends this process. In detail, if the tail member 20 is not moving when the control unit 100 proceeds to step S22, it forcibly ends the contact process in Fig. 3 and does not execute the contact process thereafter. Furthermore, if the tail member 20 is moving when the control unit 100 proceeds to step S22, it forcibly ends the contact process, returns the tail member 20 to the separated position, and does not execute the contact process thereafter.

[0057] Next, a specific example of the operation of the control unit 100 will be described. When an occupant gets into the vehicle and sits in the seat 10, and turns on the vehicle power, the timer starts counting up. When a time corresponding to the timer threshold has elapsed since the vehicle power was turned on, the control unit 100 moves the tip of the tail member 20 from the separated position toward the contact position, as shown in the order of Figures 2(a) and (b).

[0058] When the tip of the tail member 20 touches the occupant's face, the control unit 100 returns the tip of the tail member 20 to the separated position, resets the timer, and starts counting up the timer from 1. After that, when the time corresponding to the timer threshold has elapsed since the tip of the tail member 20 returned to the separated position, the control unit 100 performs contact processing again and moves the tip of the tail member 20 toward the contact position.

[0059] Therefore, the tail member 20 of the seat 10 periodically touches the face of the occupant seated in the seat 10, so the occupant feels the seat 10 like a pet, develops an attachment to the seat 10, and is comforted by the contact with the tail member 20.

[0060] As described above, according to this embodiment, the following effects can be obtained. By configuring the control unit 100 to execute contact processing by moving the movable body 22 of the tail member 20 and bringing the movable body 22 into contact with the occupant, the occupant can be made aware of the action of the tail member 20 by touch, making it easier for the occupant to notice the action of the tail member 20.

[0061] By configuring the movable body 22 to move until the control unit 100 determines that the movable body 22 has come into contact with the occupant based on information from the contact sensor 22A, the movable body 22 can be reliably brought into contact with the occupant.

[0062] Safety can be improved by configuring the control unit 100 to prohibit contact processing when it predicts a vehicle collision.

[0063] The control unit 100 may randomly select the timer threshold from a number of different values. This will cause the timing at which the tail member 20 touches the occupant to be irregular, allowing the occupant to feel that the tail member 20 is alive.

[0064] [Second embodiment] Next, a second embodiment of the present invention will be described in detail with reference to the accompanying drawings. Since this embodiment is a partial modification of the structure of the vehicle interior system 1 according to the first embodiment, components that are substantially the same as those in the first embodiment will be designated by the same reference numerals and descriptions thereof will be omitted.

[0065] As shown in Fig. 5, the vehicle interior system 1A according to the second embodiment further includes a voice acquisition unit 110 that acquires the voice of the occupant in addition to the configuration of the vehicle interior system 1 according to the first embodiment. The voice acquisition unit 110 is, for example, a microphone. The voice acquisition unit 110 may be provided in the seat 10, or may be provided in a member other than the seat 10.

[0066] In the second embodiment, the tip of the movable body 22 is provided with a pressure sensor 22B as a contact sensor.

[0067] The control unit 100 has a function of changing the movement of the movable body 22 based on the sound acquired by the sound acquisition unit 110. Specifically, the control unit 100 controls the actuator so that the pressure applied from the movable body 22 to the occupant increases as the volume of the sound acquired by the sound acquisition unit 110 increases. At this time, the control unit 100 changes the strength of the pressure applied from the movable body 22 to the occupant in the contact process based on the pressure value acquired by the pressure sensor 22B.

[0068] Specifically, the control unit 100 according to the second embodiment executes the contact process shown in FIG. In the contact process, the control unit 100 first determines whether the volume of the voice acquired from the voice acquisition unit 110 is equal to or greater than a first threshold (S31). If it is determined in step S31 that the volume of the voice is not equal to or greater than the first threshold (No), the control unit 100 ends this process.

[0069] If it is determined in step S31 that the volume of the voice is equal to or greater than the first threshold (Yes), the control unit 100 determines whether the volume of the voice is equal to or greater than a second threshold that is greater than the first threshold (S32). If it is determined in step S32 that the volume of the voice is not equal to or greater than the second threshold (No), the control unit 100 moves the tip of the tail member 20 toward the contact position (S36).

[0070] After step S36, the control unit 100 determines whether the pressure acquired from the pressure sensor 22B is equal to or greater than the first pressure value (S37). If it is determined in step S37 that the pressure is not equal to or greater than the first threshold value (No), the control unit 100 repeats the process of step S37. If it is determined in step S37 that the pressure is equal to or greater than the first threshold value (Yes), the control unit 100 returns the tip of the tail member 20 to the separated position (S35) and ends this process. Note that if the condition of step S37 is not met even after a predetermined time has elapsed in step S37, the control unit 100 proceeds to the process of step S35 and returns the tip of the tail member 20 to the separated position.

[0071] If it is determined in step S32 that the volume of the voice is equal to or greater than the second threshold (Yes), the control unit 100 moves the tip of the tail member 20 toward the contact position (S33). After step S33, the control unit 100 determines whether the pressure acquired from the pressure sensor 22B is equal to or greater than a second pressure value that is greater than the first pressure value (S34). If it is determined in step S34 that the pressure is not equal to or greater than the second threshold (No), the control unit 100 repeats the process of step S34. If it is determined in step S34 that the pressure is equal to or greater than the second threshold (Yes), the control unit 100 returns the tip of the tail member 20 to the separated position (S35) and ends this process. Note that if the condition of step S34 is not satisfied even after a predetermined time has elapsed in step S34, the control unit 100 proceeds to the process of step S35 and returns the tip of the tail member 20 to the separated position.

[0072] Next, a specific example of the operation of the control unit 100 will be described. For example, if the passenger hums, producing a sound equal to or greater than the first threshold and less than the second threshold, the control unit 100 will press the tip of the tail member 20 against the passenger's face with a first strength corresponding to the first pressure value. This allows the passenger to feel that the cat is in a good mood because of the passenger's humming and is playing with the cat's tail, allowing the passenger to enjoy communication with the cat.

[0073] For example, if the occupant shouts loudly when another vehicle cuts in front of the vehicle, the control unit 100 pushes the occupant's face with the tip of the tail member 20 at a second strength greater than the first strength. This allows the occupant to feel that they have startled the cat with their loud voice and made it angry, and they can feel sorry for the cat and reduce their anger towards the cutting-in vehicle.

[0074] [Third embodiment] Next, a third embodiment of the present invention will be described in detail with reference to the drawings as appropriate. Note that this embodiment is a partial modification of the structure of the vehicle interior system 1 according to the first embodiment, and therefore, components that are substantially the same as those in the first embodiment will be given the same reference numerals and descriptions thereof will be omitted.

[0075] As shown in FIG. 7, a vehicle interior system 1B according to the third embodiment further includes a heart rate sensor 41 and a breathing sensor 42 in addition to the configuration of the vehicle interior system 1 according to the first embodiment.

[0076] The heart rate sensor 41 and the respiration sensor 42 are sensors capable of detecting biological information of an occupant seated in the seat 10. In the following description, the occupant seated in the seat 10 will also be referred to as a "seat occupant."

[0077] The heart rate sensor 41 is a sensing device that uses capacitively coupled electrodes to measure the electrocardiogram signal of the seated person in a non-contact manner. Here, the electrocardiogram signal refers to an action potential signal that occurs in conjunction with the heartbeat of the seated person. The heartbeat sensor 41 is provided on the seat back 12. An electrocardiogram signal detected by the heartbeat sensor 41 is output to the control unit 100.

[0078] The breathing sensor 42 is provided on the seat cushion 11. The breathing sensor 42 has electrodes on the top and bottom. The breathing sensor 42 is a resistance pressure-sensitive sensor (pressure sensor) that detects a current flowing through an electrical resistance that changes in response to the breathing of a seated occupant.

[0079] Here, when pressure is applied to the electrode on the upper surface of the breathing sensor 42, the electrode on the upper surface deforms downward, increasing contact resistance and decreasing the electrical resistance value between the electrodes. An electrical signal related to this electrical resistance value is output from the breathing sensor 42 to the control unit 100. The control unit 100 calculates pressure based on the electrical signal related to the electrical resistance value and obtains breathing data based on the calculated pressure.

[0080] The heart rate sensor 41 may be provided on the seat cushion 11, and the breathing sensor 42 may be provided on the seat back 12. Alternatively, both the heart rate sensor 41 and the breathing sensor 42 may be provided on either the seat cushion 11 or the seat back 12.

[0081] The control unit 100 has a function of estimating the fatigue level of the seated occupant based on biological information acquired from at least one of the heartbeat sensor 41 and the respiration sensor 42.

[0082] As an example, the control unit 100 measures the activity level of the sympathetic nerves of the seated occupant based on the heart rate information acquired from the heart rate sensor 41. Specifically, the control unit 100 obtains the ratio (LF / HF) of the low frequency fluctuation wave (LF) to the high frequency fluctuation wave (HF) in the heart rate fluctuation as the activity level of the sympathetic nerves. Then, the control unit 100 determines the activity level of the sympathetic nerves (LF / HF) as the fatigue level. That is, according to the above index, it is estimated that the more active the sympathetic nervous activity is relative to the parasympathetic nervous activity, the higher the fatigue level of the seated occupant.

[0083] The method for estimating the fatigue level of the seated occupant is not limited to the above example. For example, the control unit 100 may determine the fatigue level of the seated occupant based on the interval between breaths or the arousal level determined based on the breath (at least a level indicating whether the occupant is in an arousal state or a low arousal state) based on information acquired from the breathing sensor 42. Specifically, the shorter the interval between breaths of the seated occupant, the higher the fatigue level may be determined to be, or the fatigue level may be determined to be high when the arousal level of the seated occupant is in a low arousal state.

[0084] Furthermore, the control unit 100 may use the total of the individual fatigue levels determined based on the sympathetic nerve activity level based on the heart rate, the breathing interval, and the arousal level as the fatigue level of the seated occupant.

[0085] The control unit 100 according to the third embodiment executes the contact process shown in FIG. In the contact process, the control unit 100 first estimates the fatigue level of the seated occupant based on biological information acquired from at least one of the heartbeat sensor 41 and the respiration sensor 42 (S51).

[0086] After step S51, the control unit 100 determines whether the fatigue level is equal to or greater than the first fatigue threshold (S52). If it is determined in step S52 that the fatigue level is not equal to or greater than the first fatigue threshold (No), the control unit 100 ends this process.

[0087] If it is determined in step S52 that the fatigue level is equal to or greater than the first fatigue threshold (Yes), the control unit 100 determines whether the fatigue level is equal to or greater than the second fatigue threshold (S53). If it is determined in step S53 that the fatigue level is equal to or greater than the second fatigue threshold (Yes), the control unit 100 moves the tip of the tail member 20 over the occupant's head to make contact with it, and then moves it back and forth from side to side to stroke the occupant's head with the tail member 20 (S54).

[0088] If it is determined in step S53 that the fatigue level is not equal to or greater than the second fatigue threshold (No), the control unit 100 moves the tip of the tail member 20 over the occupant's head, and then moves it back and forth up and down to hit the occupant's head with the tail member 20 (S56). After step S54 or step S55, the control unit 100 returns the tip of the tail member 20 to the separated position (S55), and ends this process.

[0089] Next, a specific example of the operation of the control unit 100 will be described. If the occupant's fatigue level is equal to or greater than the first fatigue level and less than the second fatigue level, for example, if the occupant is slightly tired and lacking concentration, the control unit 100 will hit the occupant on the head with the tail member 20. This allows the occupant to feel encouraged by the cat, and so they can drive with renewed enthusiasm.

[0090] If the occupant's fatigue level is equal to or higher than the second fatigue level, for example, if the occupant is very tired but continues driving without realizing that fatigue, the control unit 100 strokes the occupant's head with the tail member 20. This allows the occupant to feel that the cat is trying to put them to sleep, and they can decide to take a break even if they are unaware of their fatigue.

[0091] Since the control unit 100 executes contact processing based on biological information, the vehicle interior system 1B is personalized, and the quality of communication can be improved.

[0092] [Fourth embodiment] Next, a fourth embodiment of the present invention will be described in detail with reference to the accompanying drawings. Since this embodiment is a partial modification of the structure of the vehicle interior system 1B according to the third embodiment, components that are substantially the same as those in the third embodiment will be designated by the same reference numerals and will not be described again.

[0093] 9, the vehicle interior system 1C according to the fourth embodiment includes the same components as the vehicle interior system 1B according to the third embodiment, but also includes a second camera C2 that captures an image of the occupant's face. In the fourth embodiment, a tail member 20 is provided on each of the left and right side surfaces FL of the headrest 13. In the fourth embodiment, the tail member 20 does not include a contact sensor 22A, and the second camera C2 is used as the contact sensor.

[0094] The control unit 100 has a function of estimating the level of wakefulness of the occupant based on biological information acquired from at least one of the heart rate sensor 41 and the breathing sensor 42. The control unit 100 can determine whether the tail member 20 is touching the occupant based on image information from the second camera C2.

[0095] The control unit 100 can move the tip of the tail member 20 to any position on the occupant's face based on the image information from the second camera C2. If the occupant's face is not facing forward, the control unit 100 has the function of pushing the occupant's face with the tail member 20 to turn the occupant's face forward.

[0096] As shown in Figures 10(a) and (b), when the occupant's face is facing down, the control unit 100 moves the tip of at least one of the tail members 20 on the left and right to the occupant's forehead and pushes the occupant's forehead upward with the tail member 20. As shown in Figures 10(c) and (d), when the occupant's face is facing up, the control unit 100 moves the tip of at least one of the tail members 20 on the left and right to the occupant's chin and pushes the occupant's chin downward with the tail member 20.

[0097] Although not shown in the figures, when the occupant's face is facing left, the control unit 100 moves the tip of the left tail member 20 to the occupant's left cheek and pushes the occupant's face to the right with the tail member 20. When the occupant's face is facing right, the control unit 100 moves the tip of the right tail member 20 to the occupant's right cheek and pushes the occupant's face to the left with the tail member 20.

[0098] The control unit 100 according to the fourth embodiment executes the contact process shown in FIG. In the contact process, the control unit 100 first estimates the level of wakefulness of the occupant based on biological information acquired from at least one of the heartbeat sensor 41 and the respiration sensor 42 (S71).

[0099] After step S71, the control unit 100 determines whether the level of wakefulness is equal to or lower than the threshold (S72). If it is determined in step S72 that the level of wakefulness is not equal to or lower than the threshold (No), the control unit 100 ends this process.

[0100] If it is determined in step S72 that the wakefulness level is equal to or lower than the threshold (Yes), the control unit 100 determines whether the occupant's face is facing downward based on the image information from the second camera C2 (S73). If it is determined in step S73 that the face is facing downward (Yes), the control unit 100 moves the tail member 20 and pushes the occupant's face upward with the tail member 20 (S74).

[0101] After step S74, the control unit 100 determines whether the occupant's face is facing forward based on the image information from the second camera C2 (S75). If it is determined in step S75 that the face is not facing forward (No), the control unit 100 returns to the processing of step S74. If it is determined in step S75 that the face is facing forward (Yes), the control unit 100 returns the tail member 20 to the separated position (S76) and ends this processing.

[0102] If it is determined in step S73 that the face is not facing down (No), the control unit 100 determines whether the occupant's face is facing up or not based on the image information from the second camera C2 (S77).If it is determined in step S77 that the face is facing up (Yes), the control unit 100 moves the tail member 20 and pushes the occupant's face down with the tail member 20 (S78).

[0103] After step S78, the control unit 100 determines whether the occupant's face is facing forward based on the image information from the second camera C2 (S79). If it is determined in step S79 that the face is not facing forward (No), the control unit 100 returns to the processing of step S78. If it is determined in step S79 that the face is facing forward (Yes), the control unit 100 returns the tail member 20 to the separated position (S76) and ends this processing.

[0104] If it is determined in step S77 that the face is not facing up (No), the control unit 100 determines whether the face of the occupant is facing left or not based on the image information from the second camera C2 (S80). If it is determined in step S80 that the face is facing left (Yes), the control unit 100 moves the tail member 20 and pushes the face of the occupant to the right with the tail member 20 (S81).

[0105] After step S81, the control unit 100 determines whether the occupant's face is facing forward based on the image information from the second camera C2 (S82). If it is determined in step S82 that the face is not facing forward (No), the control unit 100 returns to the processing of step S81. If it is determined in step S82 that the face is facing forward (Yes), the control unit 100 returns the tail member 20 to the separated position (S76) and ends this processing.

[0106] If it is determined in step S80 that the face is not facing left (No), the control unit 100 determines whether the face of the occupant is facing right based on the image information from the second camera C2 (S83).If it is determined in step S83 that the face is facing right (Yes), the control unit 100 moves the tail member 20 and pushes the face of the occupant to the left with the tail member 20 (S84).

[0107] After step S84, the control unit 100 determines whether the occupant's face is facing forward based on the image information from the second camera C2 (S85). If it is determined in step S85 that the face is not facing forward (No), the control unit 100 returns to the processing of step S84. If it is determined in step S85 that the face is facing forward (Yes), the control unit 100 returns the tail member 20 to the separated position (S76) and ends this processing.

[0108] If it is determined in step S83 that the face is not facing right (No), the control unit 100 ends this process without moving the tail member 20 because the face of the occupant is facing forward.

[0109] Next, a specific example of the operation of the control unit 100 will be described. If the occupant's level of alertness is below a threshold, for example, if the occupant is slightly drowsy and has their face down, the control unit 100 moves the tip of the tail member 20 to the occupant's forehead and pushes the occupant's forehead upward. This forces the occupant's face to face forward by the tail member 20, waking up the drowsy occupant and allowing them to concentrate on driving.

[0110] [Fifth embodiment] Next, a fifth embodiment of the present invention will be described in detail with reference to the drawings as appropriate. Note that this embodiment is a partial modification of the structure of the vehicle interior system 1 according to the first embodiment, and therefore, components that are substantially the same as those in the first embodiment will be given the same reference numerals and descriptions thereof will be omitted.

[0111] As shown in FIG. 12, the vehicle interior system 1D according to the fifth embodiment further includes an air cell 80 as an example of an electric device and a seat sensor 120 in addition to the configuration of the vehicle interior system 1 according to the first embodiment.

[0112] The air cell 80 includes an inflatable / deflateable bag 81, a pump, and a tube (not shown). The pump has the function of sending air into the bag 81 and sucking air out of the bag 81, and is activated by passing electricity. The tube connects the bag 81 and the pump.

[0113] The bag 81 is embedded in the pad of the headrest 13. The bag 81 moves the seating surface F of the headrest 13 in the front-rear direction. The pump is fixed to the frame of the seat 10, for example.

[0114] Bag 81 can be deformed into a first shape, a second shape larger than the first shape, and a reference shape larger than the second shape. Bag 81 is in the reference shape during normal times when control unit 100 is not performing a contact process.

[0115] The seat sensor 120 is a sensor that detects pressure applied by the head of an occupant, and is located, for example, between the surface of the headrest 13 and the pad. In the fifth embodiment, the movable body 22 is provided at its tip with a pressure sensor 22B as a contact sensor.

[0116] The control unit 100 has a function of activating the air cell 80 when the movable body 22 is moved. More specifically, the control unit 100 executes the contact process shown in FIG. 13. In the following description, the bag 81 of the air cell 80 will also be simply referred to as the "air cell 80." Furthermore, steps S104 and S105 in FIG. 13 are substantially the same processes as steps S33 and S34 in FIG. 6, and steps S109 and S110 in FIG. 13 are substantially the same processes as steps S36 and S37 in FIG. 6, so detailed description thereof will be omitted.

[0117] In the contact process, the control unit 100 first acquires pressure (hereinafter also referred to as "seat-side pressure") from the seat sensor 120 (S101). After step S101, the control unit 100 determines whether the seat-side pressure is equal to or greater than a first pressure threshold (S102). If it is determined in step S102 that the seat-side pressure is not equal to or greater than the first pressure threshold (No), the control unit 100 ends this process.

[0118] If it is determined in step S102 that the seat-side pressure is equal to or greater than the first pressure threshold (Yes), the control unit 100 determines whether the seat-side pressure is equal to or greater than a second pressure threshold that is greater than the first pressure threshold (S103).If it is determined in step S103 that the seat-side pressure is not equal to or greater than the second pressure threshold (No), the control unit 100 contracts the air cells 80 from the reference shape to a second shape, that is, from the largest shape to a medium-sized shape (S109).

[0119] After step S109, the control unit 100 executes the processes of steps S110 and S111, thereby causing the tail member 20 to press the occupant's face with a first strength corresponding to the first pressure value. After pressing the occupant's face with the first strength (S111: Yes), the control unit 100 returns the air cell 80 to the reference shape (S107), returns the tip of the tail member 20 to the separated position (S108), and ends this process.

[0120] If it is determined in step S103 that the seat-side pressure is equal to or greater than the second pressure threshold (Yes), the control unit 100 contracts the air cell 80 from the reference shape to the first shape, that is, from the largest shape to the smallest shape (S104). After step S104, the control unit 100 executes the processes of steps S105 and S106, thereby causing the tail member 20 to press against the occupant's face with a second strength greater than the first strength. After pressing the occupant's face with the second strength (S106: Yes), the control unit 100 returns the air cell 80 to the reference shape (S107), returns the tip of the tail member 20 to the separated position (S108), and ends this process.

[0121] Next, a specific example of the operation of the control unit 100 will be described. When the occupant presses their head against the seating surface F of the headrest 13 with a third strength corresponding to the first pressure threshold, the control unit 100 slightly deflates the air cells 80 and causes the tail member 20 to push the occupant's face with a first strength. When the occupant presses their head against the seating surface F of the headrest 13 with a fourth strength greater than the third strength corresponding to the second pressure threshold, the control unit 100 greatly deflates the air cells 80 and causes the tail member 20 to push the occupant's face with a second strength greater than the first strength.

[0122] As a result, the greater the force applied by the occupant to the headrest 13, the greater the reaction from the headrest 13 and the tail member 20, so the occupant can feel that the headrest 13 and the tail member 20 are like a cat, and a sense of closeness is created.

[0123] [Sixth embodiment] Next, a sixth embodiment of the present invention will be described in detail with reference to the accompanying drawings. Since this embodiment is a partial modification of the structure of the vehicle interior system 1 according to the first embodiment, components that are substantially the same as those in the first embodiment will be designated by the same reference numerals and will not be described again.

[0124] 14, in the vehicle interior system 1E according to the sixth embodiment, tail members 20 are provided on each of the left and right side surfaces of the headrest 13. In addition to the configuration of the vehicle interior system 1 according to the first embodiment, the vehicle interior system 1E according to the sixth embodiment further includes left and right air cells 80, a left sensor 121, and a right sensor 122.

[0125] The left and right air cells 80 have substantially the same structure as the air cell 80 of the fifth embodiment, except for the size of the bag 81. The bag 81 of the left air cell 80 is located on the left side of the headrest 13. The bag 81 of the right air cell 80 is located on the right side of the headrest 13.

[0126] The left sensor 121 and the right sensor 122 are pressure sensors provided inside the headrest 13. The left sensor 121 is located between the surface of the headrest 13 and the left bag 81. The right sensor 122 is located between the surface of the headrest 13 and the right bag 81.

[0127] The control unit 100 according to the sixth embodiment executes the contact process of FIG. In the contact process, the control unit 100 first acquires pressure from the left sensor 121 and the right sensor 122 (S131). After step S131, the control unit 100 determines whether the pressure of the left sensor 121 is equal to or greater than a threshold value (S132).

[0128] If it is determined in step S132 that the pressure of the left sensor 121 is equal to or greater than the threshold (Yes), the control unit 100 causes the left air cell 80 to contract by a predetermined amount from the reference shape (S133). After step S133, the control unit 100 moves the left tail member 20 to contact the occupant's face (S134). Here, in step S134, the control unit 100 performs the same processes as steps S2 and S3 in FIG. 3.

[0129] After step S134, the control unit 100 returns the air cell 80 to its reference shape (S135), returns the tail member 20 to the separated position (S136), and ends this process. If it is determined in step S132 that the pressure of the left sensor 121 is not equal to or greater than the threshold value (No), the control unit 100 determines whether the pressure of the right sensor 122 is equal to or greater than the threshold value (S137). Note that the threshold value corresponding to the left sensor 121 and the threshold value corresponding to the right sensor 122 may be the same value or different values.

[0130] If it is determined in step S137 that the pressure of the right sensor 122 is equal to or greater than the threshold value (Yes), the control unit 100 causes the right air cell 80 to contract by a predetermined amount from the reference shape (S138). After step S138, the control unit 100 moves the right tail member 20 to contact the occupant's face (S139). Here, in step S139, the control unit 100 performs the same processes as steps S2 and S3 in FIG. 3.

[0131] After step S139, the control unit 100 returns the air cell 80 to its reference shape (S135), returns the tail member 20 to the separated position (S136), and ends this process. If it is determined in step S137 that the pressure of the right sensor 122 is not greater than the threshold (No), the control unit 100 ends this process without moving the air cell 80 and the tail member 20.

[0132] Next, a specific example of the operation of the control unit 100 will be described. When the occupant turns their face slightly to the left and the pressure of the left sensor 121 becomes equal to or greater than the threshold, the control unit 100 deflates the left air cell 80. This causes the occupant's face to turn further to the left, making it easier for the left tail member 20 to come into contact with the occupant's face. Similarly, when the occupant turns their face slightly to the right and the pressure of the right sensor 122 becomes equal to or greater than the threshold, the control unit 100 deflates the right air cell 80. This causes the occupant's face to turn further to the right, making it easier for the right tail member 20 to come into contact with the occupant's face.

[0133] The present invention is not limited to the above-described embodiment, but can be used in various forms as exemplified below.

[0134] The vehicle interior system may include a seating detection sensor that detects whether an occupant is seated in the seat. Examples of the seating detection sensor include a seating sensor on the seat and a camera that photographs the occupant. In this case, the control unit may execute the contact process when it determines that an occupant is seated in the seat based on information from the seating detection sensor, and may prohibit the contact process when it determines that an occupant is not seated in the seat. In this way, the control unit executes the contact process only after recognizing that an occupant is seated in the seat, thereby preventing malfunction and creating a sense of exclusivity that communication can only be achieved within the vehicle interior.

[0135] The electric device may be any device that moves at least a part of the seat. For example, the electric device may be any of the following devices: Reclining device for tilting the seat back Height mechanism that moves the seat up and down -Slide device that moves the seat back and forth A movable device that changes the shape of a seat by driving a bag (air cell) or a plate member that operates by letting air in (for example, a device that operates the left and right protrusions that protrude from the seating surface of a seat cushion or seat back, or a device that operates part of the seating surface of a seat back or seat cushion). A side frame front end lifting mechanism that switches the front end of the seat cushion side frame between an up position and a down position. Tilt mechanism that moves the seat cushion pan up and down - Center-folding mechanism that tilts the upper part of the seat back forward and backward Rotation mechanism that rotates the seat on a vertical axis -Cushion front / rear adjustment mechanism to adjust the length of the front end of the seat cushion A mechanism for rotating the ottoman up and down or moving it back and forth -Mechanism for rotating armrests up and down Armrest extension mechanism -Mechanism to switch armrest between extended and bent positions ·illumination Headrest speaker (The headrest speaker may rotate or move in at least one direction of front, back, left, right, up, down, etc.) Heaters installed in the seat back or seat cushion Seat blower, a seat air conditioning device that circulates air on the surface of the seat cushion and seat back -Vibration device that vibrates the seating surface

[0136] The decorative item may be located on an upper part of the seat other than the headrest. For example, the decorative item may be located on the upper surface of the seat back, on either the left or right side, or on the back. The decorative item may also be located on either the left or right side or the underside of the seat cushion. When the decorative item is located on the upper part of the seat, the movable body can come into contact with the occupant's head, making it easier for the occupant to notice the movable body coming into contact.

[0137] The contact sensor may be a camera placed in a position where it can capture an image of the occupant, or a camera provided on a movable body (for example, the tip of a tail member). In this case, the control unit may determine whether the movable body has touched the occupant based on information from the camera.

[0138] The control unit may change the destination (contact position) of the movable body depending on the conditions. For example, the control unit may move the movable body so as to contact the head of the occupant when a first condition is satisfied, and may move the movable body so as to contact the shoulder of the occupant when a second condition is satisfied.

[0139] The control unit may change the contact time, which is the time during which the movable body is in contact with the occupant, depending on the conditions. For example, the control unit may set the contact time to a first time when a first condition is satisfied, and may set the contact time to a second time, which is longer than the first time, when a second condition is satisfied.

[0140] The control unit may change the number of contacts, which is the number of times the movable body comes into contact with the occupant, depending on the conditions. For example, the control unit may set the number of contacts to a first number when a first condition is satisfied, and may set the number of contacts to a second number greater than the first number when a second condition is satisfied.

[0141] The control unit may determine the contact time or the number of contacts based on information from a contact sensor, for example.

[0142] The control unit may cause the movable body to come into contact with the occupant based on vehicle information acquired by the vehicle. In this case, the movable body can contact the occupant to notify the occupant of any information. Examples of the vehicle information include the distance between the host vehicle and another vehicle, information on whether the preceding vehicle has started moving while the host vehicle is stopped, information on whether the host vehicle will deviate from its lane, lane change timing for lane change assistance, and steering and acceleration / deceleration information for vehicle driving assistance.

[0143] The vehicle interior system may include a notification device that notifies the occupant of information by voice or display. The notification device may be, for example, an agent device such as a robot, or a navigation system. The control unit may perform contact processing after notifying the occupant using the notification device. In this way, when notifying the occupant of information by voice or display, a contact action is added as a supplementary form of communication, so that notification can be performed using both vision or hearing and touch. The control unit may, for example, change the destination (contact position) of the movable body depending on the information to be notified.

[0144] The control unit may execute the contact process randomly within a predetermined time period. The control unit may change the moving distance, moving speed, etc. of the movable body.

[0145] The control unit may execute the contact process based on the content of the voice acquired from the occupant.

[0146] The vehicle interior system includes a physical information acquisition unit that acquires the physique of the occupant, and the control unit may estimate the position of body parts such as the head and shoulders of the occupant sitting in the seat based on the physical information acquired from the physical information acquisition unit.

[0147] Examples of the physical information acquisition unit include a camera capable of photographing the occupant, a device that stores the occupant's physical information such as a smartphone or a wearable device, and multiple pressure sensors provided on the seat.

[0148] The camera may be, for example, an in-vehicle camera, an exterior camera, or a camera mounted on a movable body. In the case of an exterior camera, the control unit estimates the position of the head and shoulders of the occupant sitting in the seat based on an image of the occupant captured by the exterior camera before getting in the vehicle.

[0149] The contact strength (the strength with which the movable body pushes the occupant) may be changed depending on the contact position. For example, the contact strength may be strong on the top of the head and weak on the face.

[0150] The contact position may be set arbitrarily. For example, it may be set so as not to contact the face or head of the occupant so as not to ruin their hair or makeup. For example, the head may be set as the first position, the sides of the face as the second position, the ears as the third position, and the shoulders as the fourth position. A plurality of movable bodies may be provided, and may be capable of coming into contact with the thighs, abdomen, or arms of the occupant.

[0151] The control unit may estimate the physical and mental state of the occupant based on the biological information. The control unit may increase the frequency of contact processing when the occupant's mental state is deteriorating.

[0152] The control unit may change the posture of the seat so that the movable body is more likely to come into contact with the occupant. For example, the control unit may perform at least one of the following processes before performing the contact process. The tilt-up mechanism tilts up the front end of the seat cushion, allowing the occupant's body to lean backward. The reclining mechanism moves the seat back toward the occupant, rotating the seat back to a position where the tail member of the headrest can contact the occupant. Whether the seat back has reached a position where it can contact the occupant can be determined, for example, based on information from a pressure sensor installed in the seat back. The ottoman drive mechanism raises the ottoman, allowing the occupant's body to lean backward.

[0153] Before executing the contact process, the control unit may activate a vibration device provided on the seat to notify that the movable body will start moving.

[0154] The movable body may be provided with a heater, which can warm the part of the occupant's body that comes into contact with the movable body, thereby improving the comfort of the occupant. The headrest may be equipped with a heater.

[0155] The interior member on which the decorative item is provided is not limited to the headrest of the driver's seat, but may also be a member (seat cushion, seat back, headrest) constituting another seat such as the passenger seat. If the seat has an armrest or ottoman, the interior member may be the armrest or ottoman.

[0156] Other examples of interior components include a center console box located between the driver's seat and the passenger seat, a dashboard, inner panels of doors and vehicle side walls, a roof lining, an interior opening / closing cover of a sunroof, etc. The decorative item may be provided, for example, on the upper part of the rear surface of the seat back, the left and right bulging portions that bulge out above the seat surface of the seat cushion, the sides of the headrest, the top surface of the dashboard or above the meter hood, the center console box, etc.

[0157] The ornament is not limited to a cat's tail. For example, other examples of ornaments include models imitating body parts (ears, limbs, whiskers) of animals such as dogs and cats, stuffed toys imitating the entire body of a human or animal, models imitating characters that anthropomorphize objects or living things, models imitating plants such as flowers and trees, models of buildings such as castles, and robots. The movable body may be the arms or legs of a robot, or a device that rotates or raises and lowers the entire robot.

[0158] Changing the shape of an ornament is not limited to changing between a straight and a bent state, and any change that changes the external shape of the ornament is acceptable. For example, if the ornament is made up of air cells that can expand and contract with air, the shape of the ornament may change between a normal state and a state that is more deflated than the normal state. In this case, the actuator that changes the shape of the ornament may be a pump that switches between supplying and discharging air to the ornament.

[0159] The actuator may be an artificial muscle such as that disclosed in JP 2023-008896 A.

[0160] The ornament may also have a plurality of stacked air cells. In this case, by selecting the air cells to inflate, the shape of the ornament can be changed in multiple stages.

[0161] The decorative item may also have a shape memory alloy. In this case, a heater is provided on or around the decorative item. The shape memory alloy may be configured, for example, to assume a first straight shape when the temperature of the shape memory alloy is below a predetermined temperature, and assume a second bent shape when the temperature is above the predetermined temperature. The control unit may change the shape of the shape memory alloy by controlling the heater.

[0162] The decorative item may have a display unit, a communication unit, a speaker, etc. The decorative item may be operable by an operation input unit such as a seat, door, or navigation system.

[0163] The vehicle is not limited to an automobile, but may be any other vehicle, such as a motorcycle or a train.

[0164] Examples of methods for manufacturing a vehicle interior system include the following methods. A method for manufacturing a vehicle interior system comprising: an ornament to be attached to an interior member of a vehicle, the ornament having a movable body moved by an actuator; and a control unit, wherein the movable body is movable between a separation position away from an occupant seated in the seat and a contact position at which it can come into contact with the occupant seated in the seat; and the control unit controls the actuator to move the movable body from the separation position toward the contact position, thereby performing a contact process to bring the movable body into contact with the occupant. The method for manufacturing a vehicle interior system comprises the steps of attaching the ornament to the interior member and connecting the actuator to the control unit.

[0165] The elements described in the above-described embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
