Abstract
Description
Technical Field
[0001] This disclosure relates to a vehicle system including interior components and a control unit. Background Technology
[0002] Previously, a type of chair was known that included a wakefulness maintenance device and an indicator light showing that the wakefulness maintenance device was active (see Japanese Patent Application Publication No. 2016-193656). The wakefulness maintenance device included a breathing sensor, a control device, and a vibration unit. The control device received breathing signals from the seated person detected by the breathing sensor to determine the seated person's awakeness state; if it determined that the seated person was not awake, it activated the vibration unit. In this technology, since the seated person or those around them could be informed that the wakefulness maintenance device was working properly, drowsiness was more reliably prevented. Summary of the Invention
[0003] However, in the prior art, since the operating status of the wakefulness maintenance device is indicated by illuminating the indicator light, it may be difficult for people around to grasp the operating status of the wakefulness maintenance device and thus the state of the person seated, in situations where the light is difficult to see, such as when the environment around the seat is bright.
[0004] There is an urgent need to inform people around them about users' biological information in a more accessible and understandable way.
[0005] In view of the aforementioned background, a vehicle system is disclosed, comprising: an interior component disposed within a vehicle; a decorative element disposed on the interior component; an electric device for changing the shape of the decorative element; a sensor for acquiring biometric information of a user; and a control unit.
[0006] The control unit activates an electric device based on biological information obtained from sensors, thereby changing the shape of the ornament.
[0007] According to the structure, since the shape of the ornament is changed based on the user's biological information, the user's biological status can be more easily communicated to those around the user, even in a bright environment.
[0008] Alternatively, decorative elements can protrude from interior components.
[0009] By making decorative elements stand out from interior components, they become more noticeable, thus providing a more easily understandable message about the user's biological state to those around them.
[0010] Alternatively, the ornament can be deformed into a first shape extending in one direction and a curved second shape. When the control unit determines that the user is fatigued based on biological information obtained from the sensor, it activates the electric device to deform the ornament from the first shape to the second shape.
[0011] When an object that was originally straight is bent, it is easy to associate it with the image of a plant that was originally vibrant but has withered, or the transformation of a vibrant state into a state of fatigue. Therefore, by bending the ornament when the user is tired, people around can easily recognize that the user is tired.
[0012] Alternatively, the interior components could be the headrests of the seats, with decorative elements protruding upwards from the headrests.
[0013] By making the decorations protrude upwards from the headrest, they become more noticeable, thus providing a more easily understandable message about the user's biological state to those around them.
[0014] Alternatively, the vehicle system may also include a display unit, through which the control unit displays an image representing the user's biological state based on biological information obtained from sensors.
[0015] Therefore, the user's biological state is represented by the images and decorations displayed on the display unit, so that the user's biological state can be explained to the people around them in a more accessible way.
[0016] Alternatively, the control unit can display the character image on the display unit and change the character image based on the biological information obtained from the sensor.
[0017] Accordingly, for example, by changing the facial expressions of a character image based on biometric information, the user's biometric information can be communicated to those around them in a more accessible and understandable way.
[0018] Alternatively, the decorative item may have a touch sensor that outputs signals through user touch, and the control unit moves the decorative item based on the signals from the touch sensor.
[0019] According to the structure, the decorations move when the user touches them, thus enhancing the entertainment value.
[0020] Alternatively, the control unit can adjust the number of times the decoration moves within a specified time period based on the biological information obtained from the sensor.
[0021] Therefore, by changing the number of times the decorations are used, the user's fatigue level can be represented in multiple stages.
[0022] Alternatively, the decoration may have lighting, and the control unit may turn on the lighting based on biological information obtained from sensors.
[0023] Therefore, by using changes in lighting and the shape of decorations to represent the user's biological state, the user's biological state can be communicated to those around them in a more accessible and understandable way.
[0024] Alternatively, the decoration can be a shape that imitates a part of an animal's body.
[0025] Accordingly, for example, when the ornament is designed to mimic the shape of an animal's ear, by bending the ornament when the user is tired, people around can easily recognize that the user is tired.
[0026] Alternatively, if the control unit predicts a vehicle collision based on information from a collision detection unit installed in the vehicle, it may prohibit changes to the shape of the ornaments based on biological information, and provide a warning of a vehicle collision by moving the ornaments before the collision.
[0027] Therefore, in the event of a vehicle collision, the movement of decorative items can warn people in the vicinity of the collision.
[0028] Furthermore, conventionally, vehicle systems are known to include those that, when it is predicted that deceleration control will be transferred through auxiliary processing, tilt the seat slightly forward so that the driver feels a virtual deceleration has begun, thereby conveying the system's intention to perform condition-appropriate driving control to the driver (see Japanese Patent No. 7312378).
[0029] However, in addition to deceleration, acceleration and turning are sometimes controlled during auxiliary operations. Therefore, there is a problem that the detailed content of the auxiliary operations cannot be transmitted by simply tilting the seat as in the past.
[0030] Therefore, it is desirable to provide a vehicle system that can transmit detailed information for auxiliary processing.
[0031] In light of the aforementioned background, another form of vehicle system is one that supports the driver's driving operations through auxiliary processing that enables the vehicle to accelerate, decelerate, or change its steering angle based on the vehicle's surrounding environment.
[0032] The vehicle system includes: a seat for the user to sit on; an electric device for moving a portion of the seat surface; and a control unit.
[0033] Electrical equipment includes vibrating devices and / or air chambers.
[0034] When performing auxiliary processing, the control unit performs equipment linkage processing to enable the electric equipment to operate based on the actions of the vehicle that is running through the auxiliary processing.
[0035] According to the structure, since the vibration device or air chamber can exhibit many changes through touch, detailed information about auxiliary processing can be conveyed to the user.
[0036] Alternatively, the control unit may perform equipment linkage processing when the magnitude of the acceleration or steering angle changed through auxiliary processing exceeds a specified threshold.
[0037] According to the structure, no equipment linkage processing is performed when the acceleration or steering angle changes below a specified threshold, thus suppressing confusion and improving comfort.
[0038] Alternatively, the control unit can change the operating mode of the electric equipment based on the acceleration or steering angle changed through auxiliary processing.
[0039] According to the structure, the detailed information of the auxiliary processing can be conveyed to the user through the operation mode of the electric device.
[0040] Alternatively, the vehicle system may include multiple electric devices, and the control unit may select the electric device to operate from among them based on whether the driving operation supported by the auxiliary processing is acceleration, deceleration, right turn, or left turn.
[0041] Based on the structure described, users can obtain detailed information about the auxiliary processing according to the location of the electric equipment to be operated.
[0042] Alternatively, the electric equipment can be a vibrating device, and the control unit can change the intensity of the vibration of the vibrating device based on the magnitude of the acceleration changed through auxiliary processing.
[0043] According to the structure, for example, the greater the acceleration, the greater the intensity of the vibration, and thus the magnitude of the acceleration can be intuitively understood by the intensity of the vibration from the seating surface.
[0044] Alternatively, the electric device can be an air chamber, with at least one air chamber located on each side of the seat. The control unit expands one of the air chambers based on the steering angle changed through auxiliary processing.
[0045] According to the structure, by expanding one of the left and right air chambers, the user can understand that steering control is in progress by the pressure from one side of the seat surface.
[0046] Alternatively, the air chamber may include a bag and an air pump that allows air to flow into the bag, and the control unit may change the amount of air flowing from the air pump into the bag based on the turning angle changed by auxiliary processing.
[0047] According to the structure, since the amount of air flowing into the bag is changed based on the turning angle, for example, the user can understand the magnitude of the changed turning angle by the amount of expansion of the bag in the air chamber.
[0048] Alternatively, it may also include a display unit that shows the character, and a control unit that moves the character in coordination with the movement of the electric equipment during equipment linkage processing.
[0049] According to the structure, since the character moves in coordination with the movement of the electric equipment during the device linkage process, the user can feel that the character is undergoing auxiliary processing through the movement of the electric equipment, so that the user can feel as if the vehicle and the character are integrated.
[0050] Alternatively, at least one speaker can be installed on each side of the seat, and the control unit outputs sound from one of the left and right speakers based on the steering angle changed through auxiliary processing.
[0051] According to the structure, since sound is output from one of the left or right speakers based on the steering angle, the user can understand through auditory processing that the vehicle has turned.
[0052] Alternatively, the control unit may not perform equipment linkage processing if it predicts a vehicle collision based on information from the collision detection unit installed in the vehicle.
[0053] According to the structure described, safety can be improved in the event of a potential vehicle collision because no equipment linkage processing is performed.
[0054] Furthermore, conventionally, vehicle systems include: a first suspension system mounted between the seat and the vehicle body; a second suspension system mounted between the vehicle body and the wheels; a travel detection unit that detects the maximum and minimum travel of the second suspension system; and a first suspension system control unit that controls the first suspension system to reduce its rigidity when the travel detection unit detects the maximum or minimum travel (see Japanese Patent Application Publication No. 2000-280806). According to this technology, when a strong impact is applied from the wheels to the vehicle body due to the state of the second suspension system, the rigidity of the first suspension system is reduced, thereby mitigating the impact transmitted from the vehicle body to the seat.
[0055] However, in the prior art, the rigidity of the first suspension system is changed only according to the state of the second suspension system, and the shape of the seat surface is not changed, so it is impossible to achieve shock-resistance.
[0056] Therefore, it is desirable to provide a vehicle system that can achieve adaptive shock retention.
[0057] In view of the aforementioned background, another form of vehicle system includes: a vehicle body frame for supporting the seat; shock-absorbing components disposed between the road surface and the vehicle body frame; an electric device for moving a portion of the seat's occupant-side surface; and a control unit.
[0058] Shock-absorbing components absorb impacts from the road surface. The shock-absorbing capacity of these components can be varied.
[0059] The control unit operates the electric equipment based on the shock absorption rate.
[0060] According to the structure, since the electric device operates based on the shock absorption capacity, the occupant side of the seat can be shaped to adapt to the impact, thereby achieving shock absorption retention.
[0061] Alternatively, the electric device can be a gas chamber, and the control unit can change the size of the gas chamber based on the impact absorption rate.
[0062] According to the structure, for example, when the size of the air chamber is increased under conditions of low shock absorption, the seat becomes harder and the impact is more easily transmitted to the seat, so the user sitting in the seat can understand the state of the shock absorption component.
[0063] Alternatively, the seat may have a seat cushion and a seat back, the seat cushion and / or the seat back having a seating surface that supports the occupant, and protrusions on the left and right sides of the seating surface that protrude from the seating surface, the protrusions having air chambers.
[0064] According to the structure, for example, when the size of the air chamber is increased in the case of low shock absorption, the user-side of the protrusion moves to the user side and contacts the user, thereby improving retention.
[0065] Alternatively, the shock-absorbing component can be the vehicle's suspension system. The change in shock absorption is achieved by adjusting the damping force of the suspension system. When the damping force is less than a specified value, the control unit makes the air chamber into a first shape, so that the inner surface of the protrusion on the seat side is in a first position. When the damping force is greater than or equal to the specified value, the control unit makes the air chamber into a second shape that expands beyond the first shape, so that the inner surface is in a second position that is closer to the seat than the first position.
[0066] According to the structure, retention is improved because the user is supported by the inner side located in the second position when the damping force is above a specified value.
[0067] Alternatively, the vehicle system may also include an impact-absorbing component and a display unit that displays an image of the character. When the impact absorption rate changes, the control unit displays an image of the character's changed impact absorption rate on the display unit.
[0068] Based on the structure described, users are given the illusion that the character is changing their impact absorption, thus increasing the entertainment value.
[0069] Alternatively, the seat may also have a vibration device, and the control unit may adjust the intensity of the vibration based on the shock absorption rate.
[0070] According to the structure described, since the intensity of the vibration of the vibrating device is changed based on the shock absorption rate, the user can understand that the shock absorption rate has changed through the intensity of the vibration. For example, by increasing the intensity of the vibration when the shock absorption rate is low, the user can intuitively understand that the shock absorption rate has changed through the intensity of the vibration.
[0071] Alternatively, the protrusion may have a vibration device, which is activated when the control unit moves from the inner side through the air chamber toward the person seated.
[0072] Alternatively, the protrusion may have a sensor that detects contact between the inner side and the seated person, and the control unit may determine the size of the air chamber based on the information obtained from the sensor when the inner side moves toward the seated person through the air chamber.
[0073] Alternatively, the sensor can be a pressure sensor, and the control unit can activate the vibration equipment when the pressure value obtained from the sensor exceeds a threshold.
[0074] According to the structure, since the vibration device operates when the protrusion is in close contact with the user, it can reliably transmit vibration to the user.
[0075] Alternatively, the impact-absorbing component can be an adjustment device that adjusts the hardness of the tire; changes in impact absorption are made by adjusting the hardness of the tire.
[0076] Alternatively, the vehicle system may also include an operating unit, which is operated by the occupant and used to change the impact absorption rate of the impact absorbing components.
[0077] Furthermore, conventionally, vehicle systems include: a robot mounted on an instrument panel; a detection unit that detects the motion patterns of objects inside and outside the vehicle; and a control unit that enables the robot to perform actions related to the motion patterns (see Japanese Patent Application Publication No. 2023-167327).
[0078] However, in existing technologies, since it is only the robot that moves, it is not entertaining enough.
[0079] Therefore, in vehicle systems that include robots and control units, there is a desire to improve the entertainment value of vehicle systems.
[0080] In light of the aforementioned background, another form of vehicle system includes: a seat having electric devices; a robot configured at a position visually identifiable by the user seated on the seat; and a control unit.
[0081] The control unit performs linkage processing to coordinate the robot's movements with the movements of the electric equipment.
[0082] According to the structure described, the entertainment value is improved compared to a structure where only the robot moves, because the robot and the seat are linked by electric devices.
[0083] Alternatively, the control unit can activate the electric equipment based on the robot's movements during the linkage process.
[0084] According to the structure, by activating the electric devices of the seat in accordance with the robot's movements, the user can also experience the robot's actions, thus enhancing the entertainment value.
[0085] Alternatively, the vehicle system may also include an operating unit for operating electric equipment, and the control unit performs linkage processing based on information obtained from the operating unit.
[0086] Based on the aforementioned structure, a sense of intimacy is generated by the robot mimicking the movements of the chair, thus enhancing the entertainment value.
[0087] Alternatively, the seat may have sensors that detect when a user touches the seat, and the control unit may perform linkage processing based on the information obtained from the sensors.
[0088] According to the structure, when a user touches the seat, the seat and the robot move, allowing the user to feel that they are communicating with the robot through the seat, thus enhancing the entertainment experience.
[0089] Alternatively, the sensor can be positioned on a side of the seat away from the seating surface.
[0090] Alternatively, the seat may have: a second electric device, different from the electric device; and a second sensor, which detects when the user touches the seat and is positioned at a different location than the sensor. The control unit, based on information from the sensor, causes the robot to run in a first action and the electric device to operate, and based on information from the second sensor, causes the robot to run in a second action, different from the first action, and the second electric device to operate.
[0091] According to the structure, the entertainment value is enhanced because the robot moves with the seat in a manner corresponding to the position of the seat touched by the user.
[0092] Alternatively, the vehicle system may also include a sound acquisition unit that acquires sound, and the control unit performs linkage processing based on the operation commands from the user acquired by the sound acquisition unit.
[0093] Alternatively, the robot may have a display unit that shows an image of a chair that mimics the chair, and the control unit may move the image of the chair during linkage processing.
[0094] Based on the structure described, users can easily understand the seat's movements through the seat image.
[0095] Alternatively, the vehicle system may include multiple seats, and the control unit may perform linkage processing on a specified seat among the multiple seats, causing the robot to move so that the display unit faces the specified seat, and then perform linkage processing.
[0096] According to the structure, when the linkage process is performed on the designated seat, since the display unit is facing the designated seat, the user sitting in the designated seat can easily observe the seat image and feel that they are communicating with the robot.
[0097] Alternatively, the vehicle system may also include an acceleration sensor that detects the acceleration in the forward and backward direction of the vehicle, the robot is able to tilt in the forward and backward direction, the electric device is an air chamber that moves a portion of the user side surface of the seat, and the control unit tilts the robot in the forward and backward direction and activates the air chamber based on the acceleration obtained from the acceleration sensor.
[0098] According to the structure, the user can feel the acceleration in the front and rear directions of the vehicle through the tilting of the robot and the operation of the air chamber, so the user can feel a sense of unity with the vehicle.
[0099] Alternatively, the vehicle system may also include an acceleration sensor that detects the acceleration in the left and right directions of the vehicle, the robot can tilt in the left and right directions, the electric device is an air chamber that moves a part of the user side surface of the seat, the seat has a seating surface that supports the user and protrusions on the left and right sides of the seating surface that protrude from the seating surface, the protrusions have air chambers, and the control unit tilts the robot in the left and right directions and activates the air chambers based on the acceleration obtained from the acceleration sensor.
[0100] According to the structure, the user can feel the acceleration in the left and right directions of the vehicle through the tilting of the robot and the operation of the air chamber, so the user can feel a sense of unity with the vehicle.
[0101] Alternatively, the vehicle system may also include a collision detection unit located in the vehicle, and the control unit may move the robot and electric equipment if a collision is predicted based on information obtained from the collision detection unit.
[0102] According to the structure described, in the event of a potential vehicle collision, the user can be notified of the possibility of a collision by moving the robot and electric equipment, thus improving safety. Attached Figure Description

[0160] [First Implementation Method]
[0161] Hereinafter, the vehicle system of the first embodiment will be described with reference to the accompanying drawings.
[0162] like Figure 1 As shown, vehicle system 1 includes: a seat 10, as an example of an interior component; a decorative element 20, disposed on the seat 10; a camera 30, as an example of a collision detection unit; a monitor 40, as an example of a display unit; and a control unit 50. The seat 10, camera 30, and monitor 40 are disposed inside the vehicle C, specifically in a position facing the passenger compartment. In this embodiment, the seat 10 is designated as the driver's seat.
[0163] Camera 30 is a camera that takes pictures of the front of vehicle C. The image information captured by camera 30 is output to control unit 50.
[0164] The monitor 40 has a screen for displaying images. The images displayed on the monitor 40 can be changed by the control unit 50. The monitor 40 can be, for example, positioned on the dashboard below the rearview mirror.
[0165] like Figure 2 As shown, the seat 10 has a seat body 10A, and a heartbeat sensor 61 and a breathing sensor 62 as examples of sensors.
[0166] The seat body 10A is a component with a seat surface that supports the user. The seat body 10A includes a seat cushion 11, a seat back 12, and a headrest 13. The seat cushion 11, seat back 12, and headrest 13 each have a metal frame forming the skeleton, a padding covering the frame, and a cover covering the padding. The padding includes urethane foam, etc. The cover includes synthetic leather or fabric, etc. The upper surface of the seat cushion 11 is the seat surface. The front surfaces of the seat back 12 and headrest 13 are the seat surfaces.
[0167] The heart rate sensor 61 and the respiration sensor 62 are sensors that acquire biometric information of the user seated in the seat 10. In the following description, the user seated in the seat 10 is also referred to as the "seat user".
[0168] The heart rate sensor 61 is a sensing device that uses capacitively coupled electrodes to measure the electrocardiogram (ECG) signal of a seated person non-contactly. Here, the ECG signal refers to the active potential signal generated along with the beating of the seated person's heart.
[0169] A heart rate sensor 61 is installed on the seat back 12. The electrocardiogram signal detected by the heart rate sensor 61 is output to the control unit 50.
[0170] A breathing sensor 62 is disposed on the seat cushion 11. The breathing sensor 62 has electrodes at the top and bottom. The breathing sensor 62 is a resistive pressure sensor (pressure sensor) that detects current flowing through a resistor that changes according to the occupant's breathing.
[0171] Here, when the pressure applied to the electrodes on the upper surface of the breathing sensor 62 causes the electrodes to deform downwards, thereby increasing the contact resistance, the resistance between the electrodes decreases. An electrical signal related to this resistance value is output from the breathing sensor 62 to the control unit 50. The control unit 50 calculates the pressure based on the electrical signal related to the resistance value and obtains breathing data based on the calculated pressure.
[0172] Alternatively, the heart rate sensor 61 can be installed on the seat cushion 11, and the breathing sensor 62 can be installed on the seat back 12.
[0173] The control unit 50 includes a central processing unit (CPU), read-only memory (ROM), random access memory (RAM), and rewritable non-volatile memory (not shown), and executes pre-stored programs. The control unit 50 has the following function: based on biological information obtained from at least one of the heart rate sensor 61 and the respiration sensor 62, it estimates the fatigue level of the seated person.
[0174] As an example, the control unit 50 measures the activity level of the occupant's sympathetic nervous system based on heartbeat information obtained from the heartbeat sensor 61. Specifically, the control unit 50 obtains the ratio (LF / HF) of the low-frequency fluctuation wave (low frequency, LF) to the high-frequency fluctuation wave (high frequency, HF) of the heartbeat as the activity level of the sympathetic nervous system. Then, the control unit 50 sets the activity level of the sympathetic nervous system (LF / HF) as the fatigue level.
[0175] That is, based on the aforementioned indicators, it is inferred that the more active the sympathetic nervous system is compared to the parasympathetic nervous system, the higher the fatigue level of the seated person.
[0176] Furthermore, the method for estimating the fatigue level of the seated person is not limited to the examples described above. For example, the control unit 50 may determine the fatigue level of the seated person based on information obtained from the breathing sensor 62, and according to the breathing interval, or the level of alertness determined based on breathing (at least indicating whether the person is in a state of alertness or a state of low alertness). Specifically, it is also possible that the shorter the breathing interval of the seated person, the higher the fatigue level is determined, or that the fatigue level is determined to be high if the seated person's level of alertness is low.
[0177] In addition, the control unit 50 may also use the sum of various fatigue levels determined separately based on the activity of the sympathetic nervous system based on heartbeat, respiratory interval, and level of alertness as the fatigue level of the seated person.
[0178] Two decorative ornaments 20 are provided on the headrest 13 in such a way that they protrude upwards from the headrest 13. The two decorative ornaments 20 are arranged with a gap between them on the left and right sides.
[0179] The ornament 20 is shaped to resemble a part of an animal's body. In this embodiment, the ornament 20 is shaped to resemble a cat's ear. More specifically, the ornament 20 is triangular in shape when viewed from the front, such that its width gradually decreases from bottom to top.
[0180] like Figure 3 As shown, the decorative element 20 includes a first link 21, a second link 22, a winch 23 (an example of an electric device), a wire 24, a gasket 25, and a skin 26. Furthermore, the left and right decorative elements 20 have the same structure.
[0181] The first link 21 is fixed to the upper surface of the winch 23 in such a way that it extends upward from the winch 23.
[0182] The second link 22 is rotatably connected to the upper end of the first link 21. The second link 22 is capable of... Figure 3 (a) The standing position shown is the same as Figure 3 Rotate between the tilting positions shown in (b).
[0183] When the second link 22 is in the upright position, its upper end is positioned slightly forward of its lower end. When the second link 22 is in the tilted position, its upper end is positioned further downward of its lower end. The angle between the front surface of the first link 21 and the front surface of the second link 22 (hereinafter also referred to as the "link angle") is smaller when the second link 22 is in the tilted position compared to when it is in the upright position.
[0184] When the second link 22 is in the upright position, the link angle is greater than 90°. When the second link 22 is in the tilted position, the link angle is less than 90°.
[0185] The second link 22 is subjected to force from the upright position toward the tilted position via a spring (not shown). One end of the wire 24 is fixed to the upper end of the second link 22.
[0186] The winch 23 functions to rotate the second link 22 between an upright position and a tilted position by winding or releasing the tension of the wire 24. Specifically, when the second link 22 is in the tilted position, and the winch 23 is rotated forward to wind the wire 24, the second link 22 rotates from the tilted position to the upright position against the force applied by the spring. When the second link 22 is in the upright position, and the winch 23 is rotated in the reverse direction to release the tension of the wire 24, the second link 22 rotates from the upright position to the tilted position due to the force applied by the spring.
[0187] Alternatively, the spring can be omitted, and the second link 22 rotates from the upright position to the tilted position by its own weight. Conversely, in the opposite embodiment, the spring can also apply force to the second link 22 from the tilted position toward the upright position. In this case, the second link 22 can also be rotated from the upright position to the tilted position by using a winch 23 to wind the wire 24.
[0188] The liner 25 comprises urethane foam, etc., and covers the first connecting rod 21, the second connecting rod 22, and the winch 23. The liner 25 is shaped to mimic cat ears.
[0189] The outer skin 26 comprises synthetic leather or fabric, and is covered with padding 25.
[0190] The pad 25 and the skin 26 can deform as the second link 22 rotates.
[0191] The ornament 20 constructed as described above can be transformed into Figure 3 (a) The first shape shown, and Figure 3 (b) shows the second shape. In the first shape, the ornament 20 extends from the headrest 13 in one direction, specifically upwards. In the second shape, the ornament 20 bends with its front end facing forward and diagonally downwards. The ornament 20 changes shape through the operation of the winch 23 and the spring.
[0192] The headrest 13 has a recess 13A for inserting a decorative item 20. The decorative item 20 is detachable from the headrest 13. Both the decorative item 20 and the headrest 13 have connectors. When the connectors are connected, the winch 23 is electrically connected to the control unit 50.
[0193] In addition, the decorative item 20 can be fixed to the headrest 13 without being removed.
[0194] Return to Figure 2 The control unit 50 has the following function: based on biometric information obtained from at least one of the heartbeat sensor 61 and the breathing sensor 62, it activates at least one winch 23 on the left and right sides, thereby changing the shape of the ornament 20. Specifically, when the control unit 50 determines that the user is fatigued based on biometric information obtained from at least one of the heartbeat sensor 61 and the breathing sensor 62, it activates the winch 23 to deform the ornament 20 from a first shape to a second shape. In this embodiment, the control unit 50, based on the fatigue level inferred from the biometric information, bends only one side of the ornament 20, or bends both sides of the ornament 20 (see reference). Figure 5 ).
[0195] The control unit 50 has the following function: based on bio-information obtained from at least one of the heartbeat sensor 61 and the respiration sensor 62, it displays a character image representing the user's bio-state on the monitor 40. Specifically, the control unit 50 changes the facial expression of the character image displayed on the monitor 40 based on the fatigue level inferred from the bio-information (see [reference]). Figure 5 ).
[0196] In addition, the control unit 50 has the following function: based on information from the camera 30 installed in the vehicle C, it predicts whether a collision will occur in the vehicle C. If a collision is predicted, the control unit 50 prohibits changes to the shape of the ornament 20 based on biological information, and provides a warning of a collision to the vehicle C by moving the ornament 20 before the collision.
[0197] In detail, when a collision with vehicle C is predicted, the control unit 50 moves the ornament 20 in a movement different from the movement of the ornament 20 based on biometric information. In this embodiment, when a collision with vehicle C is predicted, the control unit 50 uses the left and right ornaments 20 to alternately perform multiple bending or stretching movements to make the ornaments 20 bend or stretch.
[0198] Next, the operation of the control unit 50 will be described in detail. Furthermore, in the following description, the decorative item 20 will also be referred to simply as "cat ears". Additionally, in the following description, fatigue level will be estimated using both heart rate information detected by the heart rate sensor 61 and breathing information detected by the breathing sensor 62.
[0199] Control Unit 50 repeatedly executes Figure 4 The processing shown.
[0200] exist Figure 4 In the process shown, the control unit 50 first obtains heartbeat information from the heartbeat sensor 61 and breathing information from the breathing sensor 62 (S1).
[0201] After step S1, the control unit 50 estimates the fatigue level based on heart rate and respiratory information (S2). After step S2, the control unit 50 determines whether the fatigue level is above the first threshold TH1 (S3).
[0202] If, in step S3, it is determined that the fatigue level is not above the first threshold TH1 (No), the control unit 50 adjusts the facial expression of the character on the monitor 40 screen to... Figure 5 (a) The normal state as shown in the figure (S13).
[0203] If in step S3 it is determined that the fatigue level is above the first threshold TH1 (Yes), the control unit 50 determines whether the fatigue level is above the second threshold TH2, which is greater than the first threshold TH1 (S4). If in step S4 it is determined that the fatigue level is not above the second threshold TH2 (No), the control unit 50 only operates the winch 23 on one side and only bends the cat ear on one side (S11).
[0204] After step S11, the control unit 50 adjusts the facial expression of the character on the monitor 40 screen to... Figure 5(b) shows the first fatigue state (S12). Furthermore, the expression in the first fatigue state can be any expression as long as it is slightly more tired than the normal state.
[0205] If, in step S4, it is determined that the fatigue level is above the second threshold TH2 (Yes), the control unit 50 operates the left and right winches 23 to bend the left and right cat ears (S5). Furthermore, in step S5, if one side of the cat ear is already bent, the control unit 50 only operates the winch 23 corresponding to the unbent cat ear, thereby bending the left and right cat ears.
[0206] After step S5, the control unit 50 adjusts the facial expression of the character on the monitor 40 screen to... Figure 5 (c) shows the second fatigue state (S6). Furthermore, the expression in the second fatigue state can be any expression, as long as it is more tired than the expression in the first fatigue state.
[0207] After step S6, step S12, or step S13, the control unit 50 acquires information from the camera 30 (S7). After step S7, the control unit 50 determines, based on the information acquired from the camera 30, whether there is a possibility of a collision with vehicle C (S8).
[0208] If it is determined in step S8 that there is no possibility of collision (No), the control unit 50 directly terminates the process. If it is determined in step S8 that there is a possibility of collision (Yes), the control unit 50 causes the left and right winches 23 to work alternately multiple times, thereby causing the left and right cat ears to flex and extend alternately multiple times (S9).
[0209] After step S9, the control unit 50 displays a collision warning on the screen of the monitor 40 (S10) and ends the process. Furthermore, the collision warning may be an image of text such as "Collision may occur, please be careful," or an image of a car colliding with another car.
[0210] Furthermore, the condition for restoring the bent cat ears to their original upright state can be any condition. For example, the condition can be that the user moves away from the seat 10, and the control unit 50 activates the winch 23 to restore the bent cat ears to their upright state. The determination of whether the user has moved away from the seat 10 can be based on information from at least one of the heartbeat sensor 61 and the breathing sensor 62, or it can be based on a signal from a seating sensor that detects the user's seating position.
[0211] Next, a specific example of the operation of the control unit 50 will be explained.
[0212] When a user is seated in seat 10 in a state of high energy, the control unit 50 determines, based on information from the heart rate sensor 61 and the breathing sensor 62, that the fatigue level is less than a first threshold TH1. Figure 5 As shown in (a), keep the left and right cat ears upright and make the character's expression on the screen normal (S1~S3: No → S13).
[0213] When the user's fatigue level due to driving vehicle C reaches or exceeds the first threshold TH1 but is less than the second threshold TH2, such as Figure 5 As shown in (b), the control unit 50 bends one side of the cat ear and sets the character's expression on the screen to a first state of fatigue (S1-S3: Yes → S4: No → S11, S12). By bending one side of the cat ear in this way, even someone sitting in the back seat who has difficulty observing the screen on the monitor 40 can notice the user's change in expression and thus urge the user to rest. In addition, the user or the person sitting in the front passenger seat can know the user's level of fatigue by observing the expression of the character displayed on the monitor 40.
[0214] Users urged to rest sometimes believe they are still energetic and continue driving. In such cases, when prolonged driving causes the user's fatigue level to reach or exceed the second threshold TH2, such as... Figure 5 As shown in (c), the control unit 50 bends both the left and right cat ears and sets the character's expression on the screen to a second state of fatigue (S1-S3: Yes → S4: Yes → S5, S6). Thus, a person sitting in the back seat can understand that their fatigue level has reached its peak by noticing both the left and right cat ears bending, and can be strongly advised to rest. Furthermore, by knowing that the character's expression displayed on the monitor 40 is quite tired, and considering the safety of fellow passengers, the user will have to rest, thus preventing accidents caused by the user's overconfidence.
[0215] Furthermore, in the event of a predicted collision with vehicle C, the control unit 50 causes the cat ears to alternately flex and extend. Passengers in the rear seats, sensing the uneasy atmosphere through the unusual movements of the cat ears, can naturally correct their posture, thus preparing for a collision.
[0216] Based on this embodiment, the following effects can be obtained.
[0217] Because the shape of the decoration 20 is changed according to the user's biometric information, the user's biometric status can be communicated to those around the user in a more easily understandable way, even in a bright environment.
[0218] By protruding upwards from the headrest 13, the ornament 20 becomes more conspicuous, thus making it easier for those around to understand the user's biological state.
[0219] When an object that was originally straight bends, it's easy to associate it with a vibrant plant withering, or a state of fatigue. Therefore, by bending the ornament 20 when the user is fatigued, those around them can easily recognize that the user is tired. In particular, in this embodiment, since the ornament 20 is made into cat ears, bending the cat ears from a straight state easily evokes the image of a cat being tired, thus making it easy for those around them to recognize that the user is tired.
[0220] Because the user's biological state is represented by the deformation of the decoration 20 and the expressions of the characters on the screen, the user's biological state can be communicated to those around them in a more accessible and understandable way.
[0221] In the event that vehicle C is about to collide, the movement of the decorative item 20 can warn people around of the collision.
[0222] By designing a simple structure that allows the ornament to bend and stretch using the first link 21, the second link 22, the winch 23, and the wire 24, the ornament can be compactly constructed and lightweight.
[0223] [Second Implementation]
[0224] Next, the second embodiment of the vehicle system will be described. Furthermore, since the structure of the decorative element 20 and the processing of the control unit 50 in the first embodiment are slightly modified in this embodiment, components or processes that are substantially the same as those in the first embodiment will be marked with the same symbols, and their descriptions will be omitted.
[0225] Although the decorative item 20 of the second embodiment is not shown in the figure, it has illumination. The illumination can be, for example, an illumination device disposed on the inside of the skin 26, or the skin 26 itself can be made of electronic paper and serve as illumination. The illumination can change the color of the light.
[0226] The control unit 50 has the following function: to illuminate the lighting based on biological information obtained from at least one of the heartbeat sensor 61 and the respiration sensor 62. In this embodiment, the control unit 50, like in the first embodiment, infers fatigue level based on heartbeat and respiration information, and changes the color of the illumination light according to the fatigue level.
[0227] In detail, the control unit 50 of the second embodiment performs... Figure 6 The processing shown. Figure 6 The process shown is in Figure 4The process shown includes new steps S31 and S32.
[0228] When it is determined in step S4 that the fatigue level is above the second threshold TH2 (Yes), the control unit 50 bends the left and right cat ears and makes the character's expression a second fatigue state (S5, S6). Then, by emitting red light from the illumination source, the cat ears glow red (S31). After step S31, the control unit 50 executes the processing of step S7.
[0229] If, in step S4, it is determined that the fatigue level is not above the second threshold TH2 (No), the control unit 50 bends one side of the cat ear and sets the character's expression to the first fatigue state (S11, S12). Then, by emitting blue light from the illumination source, the cat ear glows blue (S32). After step S32, the control unit 50 executes the processing of step S7.
[0230] According to the second embodiment, since the user's fatigue level is expressed through lighting and changes in the shape of the decorations 20, the user's fatigue level can be communicated to those around them in a more easily understandable way.
[0231] [Third Implementation Method]
[0232] Next, a third embodiment of the vehicle system will be described. Furthermore, since the processing of the control unit 50 in the first embodiment is slightly modified in this embodiment, components or processes that are substantially the same as those in the first embodiment will be labeled with the same symbols, and their descriptions will be omitted.
[0233] The control unit 50 in the third embodiment has the following function: based on biological information obtained from at least one of the heartbeat sensor 61 and the breathing sensor 62, it changes the number of times the ornament 20 moves within a predetermined time period. In this embodiment, the control unit 50, like in the first embodiment, estimates the fatigue level based on heartbeat and breathing information, and changes the number of times the ornament 20 moves within a predetermined time period according to the fatigue level.
[0234] In detail, the control unit 50 of the third embodiment performs... Figure 7 The processing shown. Figure 7 The process shown is a replacement Figure 4 The process shown in the diagram has been modified by adding new steps S51 and S52 to steps S5 and S11.
[0235] If, in step S4, it is determined that the fatigue level is above the second threshold TH2 (Yes), the control unit 50 operates the winch 23 to flex and extend the cat's ear three times within a specified time (S51), and then proceeds to step S6. If, in step S4, it is determined that the fatigue level is not above the second threshold TH2 (No), the control unit 50 operates the winch 23 to flex and extend the cat's ear once within a specified time (S52), and then proceeds to step S12.
[0236] In addition, the cat ears moved in steps S51 and S52 can be either one of the left or right sides, or both sides.
[0237] According to the third embodiment, by changing the number of times the decoration 20 moves, the user's fatigue level can be represented in multiple stages.
[0238] [Fourth Implementation Method]
[0239] Next, the fourth embodiment of the vehicle system will be described. Furthermore, since the structure of the decorative element 20 and the processing of the control unit 50 in the first embodiment are slightly modified in this embodiment, components or processes that are substantially the same as those in the first embodiment will be marked with the same symbols, and their descriptions will be omitted.
[0240] like Figure 8 As shown, the decorative item 320 of the fourth embodiment has a movable part 320A and a base part 320B. The movable part 320A is rotatably supported on the base part 320B about an axis along the vertical direction.
[0241] In addition to having the same first link 21, second link 22, winch 23, wire 24, pad 25, and skin 26 as in the first embodiment, the movable part 320A also has a touch sensor 321. The touch sensor 321 is a sensor that outputs a signal through direct or indirect touch by the user. For example, a pressure sensor or a capacitive sensor can be used as the touch sensor 321.
[0242] The base portion 320B includes a motor 322, a pad 323, and a skin 324.
[0243] Motor 322 is a motor used to rotate movable part 320A. The output shaft of motor 322 is fixed to winch 23.
[0244] The liner 323 contains urethane foam, etc., and covers the motor 322.
[0245] The outer skin 324 includes synthetic leather or fabric, and covers the padding 323.
[0246] The base portion 320B is embedded in the recess 13A of the headrest 13.
[0247] The control unit 50 has the function of moving the ornament 320 based on the signal from the touch sensor 321. In this embodiment, the control unit 50 operates the motor 322 based on the signal from the touch sensor 321, thereby rotating the movable part 320A.
[0248] In detail, the control unit 50 executes Figure 9 The processing shown. Figure 9 The process shown is in Figure 4 The process shown includes new steps S71 and S72.
[0249] exist Figure 9 In the process shown, the control unit 50 first determines whether the user has touched the cat ears based on the signal from the touch sensor 321 (S71). If it is determined in step S71 that the user has not touched the cat ears (No), the control unit 50 proceeds to the process in step S1.
[0250] If it is determined in step S71 that the user has touched the cat ear (yes), the control unit 50 activates the motor 322 to rotate the movable part 320A of the cat ear (S72). After step S72, the control unit 50 proceeds to the processing in step S7.
[0251] According to the fourth embodiment, when a user touches the ornament 320, the movable part 320A of the ornament 320 will move, thereby enhancing the entertainment value.
[0252] [Fifth Implementation]
[0253] Next, the fifth embodiment of the vehicle system will be described. Furthermore, since the structure of the decorative element 320 in the fourth embodiment is slightly modified in this embodiment, components or processes that are substantially the same as those in the fourth embodiment will be labeled with the same symbols, and their descriptions will be omitted.
[0254] like Figure 10 As shown, the decorative item 420 of the fifth embodiment has a base portion 420B that is different from that of the fourth embodiment, except that it has the same movable part 320A as the fourth embodiment.
[0255] An electric cylinder 422 is provided in the base portion 420B instead of the motor 322 in the base portion 320B of the fourth embodiment. The electric cylinder 422 moves the movable portion 320A up and down.
[0256] The control unit 50 of the fifth embodiment operates the electric cylinder 422 based on a signal from the touch sensor 321, thereby moving the movable part 320A up and down. Specifically, as long as... Figure 9The process of step S72 in the process shown can be replaced by the process of moving the movable part 320A of the cat ear up and down.
[0257] In addition, the structures of the fourth and fifth embodiments can be combined to form a structure in which the movable part of the ornament can rotate and move up and down.
[0258] Interior trim pieces with decorative accents are not limited to the driver's seat headrest. For example, such as... Figure 11 As shown, the interior trim components can be components (seat cushions, seat backs, headrests) that constitute at least one of the seats R1 in the first row, R2 in the second row, or R3 in the third row. Furthermore, although not shown in the illustration, if the seats have armrests or leg rests, the interior trim components can also be armrests or leg rests.
[0259] Other examples of interior components include: the center console storage box 71 located between the driver's and passenger's seats, the instrument panel 72, the interior panels 73 of the doors or vehicle side walls, the roof 74, and the cover 75 for opening / closing the sunroof. Decorative items 20 may be located, for example, on the upper part of the back of the seat back, on the left or right bulges extending upwards from the seat cushion, on the sides of the headrest, on the upper surface of the instrument panel 72 or above the meter hood, and in the center console storage box 71.
[0260] Decorations are not limited to cat ears. Other examples of decorations include: models that imitate parts of the body of animals such as dogs or cats (limbs, whiskers, tails); dolls that imitate the whole body of a person / animal; models that imitate anthropomorphized characters such as objects or creatures; models that imitate plants such as flowers or trees; and models of buildings such as castles.
[0261] The shape of the ornament can be changed, not limited to a straight or curved state; any change is permissible as long as the shape of the ornament changes. For example, if the ornament is composed of an air chamber that can expand and contract with air, its shape can be changed to a normal state or a more shrunken state than normal. In such cases, the electric device for changing the shape of the ornament can be a pump that switches the supply / discharge of air to and from the ornament.
[0262] Alternatively, the ornament may have multiple stacked air chambers. In this case, by selecting which air chambers to inflate, the shape of the ornament can be changed in multiple stages.
[0263] Alternatively, decorative items may also incorporate shape memory alloys. In this case, a heater is placed around the decorative item or the decorative item itself. The shape memory alloy may, for example, be structured such that it forms a first shape that extends straight when the temperature of the shape memory alloy is below a specified temperature, and a second shape that bends when the temperature is above the specified temperature. The control unit can also change the shape of the shape memory alloy by controlling the heater.
[0264] As a sensor for acquiring information about a living organism, a sensor that detects at least one of the following: brain waves, facial expressions, gaze, respiration, heartbeat, pulse, and sound can be used. A camera can be used as a sensor for detecting facial expressions or gaze. The camera simply needs to be positioned to capture images of the face of the user seated in the chair.
[0265] The conditions for deforming the ornament are not limited to fatigue level; any biological information or information inferred from biological information is acceptable. For example, the control unit can infer the user's physical condition based on pulse, and deform the ornament if the user's physical condition is determined to be poor.
[0266] The control unit can infer the user's emotions based on heart rate, breathing, facial expressions, pulse waves, etc., and change the shape of the decorative item accordingly. Furthermore, when the decorative item is illuminated, the control unit can also change its color based on the user's emotions. For example, if the control unit determines the user is angry, it can set the decorative item to red; if it determines the user is calm, it can set the decorative item to blue. In these cases, the image displayed on the screen representing the user's biological state can be an image of a character's facial expression representing the user's emotions, or an image of text.
[0267] In addition, the control unit can flash the lights to notify of the abnormality when it determines that there is an abnormality in the body condition based on pulse waves, heartbeats, etc., and can also make the decorations move faster than usual. At the same time, the control unit can also output displays, sounds, and lights to notify of abnormality detection.
[0268] In addition, the control unit may perform a first process (e.g., change of lighting color) when the fatigue level is above a first threshold and below a second threshold that is greater than the first threshold, and perform a second process (action of decorations) when the fatigue level is above the second threshold.
[0269] In addition, the control unit can also move or rotate the cat ears up and down when the fatigue level is less than the first threshold, that is, when the user is energetic.
[0270] The display of fatigue levels based on the display unit is not limited to the character's facial expressions; it can be numerical values or meters indicating fatigue levels, or it can be the character's colors or movements, or the colors or movements of images that mimic decorations. For example, the control unit can also display an image of the user's virtual character with cat ears (mimicking images of decorations) attached to their face, using a color that corresponds to the color of the decoration's lighting to display the color of the cat ears. In other words, the display unit can also display the state of the decoration's lighting color.
[0271] The control unit can also display a cat as a character on the screen. In addition, the character can be an animal other than a cat, or it can be a character that anthropomorphizes objects or creatures.
[0272] When the character is set as a cat, the control unit can also display a dynamic image of a cat jumping on the screen, causing the movable parts of the ornament to move up and down, if the user's fatigue level is less than a first threshold. Alternatively, if the user's fatigue level is greater than the first threshold, the control unit can display an image of a cat sleeping on the screen, causing the movable parts of the ornament to rotate by a predetermined angle.
[0273] The control unit can also make the cat in the picture smile when the user is in a happy mood, and make the cat ears, which are decorative, move up and down for a specified period of time. The control unit can also make the cat in the picture look sad and make the cat ears, which are decorative, bend when the user is in a sad mood.
[0274] The control unit can also determine whether the user is startled based on factors such as heart rate. In such cases, for example, if the control unit determines that the user is not startled, it slightly bends the cat ears, which are decorative items. Alternatively, if the control unit determines that the user is startled, it makes the cat ears, which are decorative items, stand upright compared to when the user is not startled.
[0275] Additionally, the control unit can also, when the user's fatigue level is less than a first threshold, set the lighting color of the ornament to a warm color and cause the movable part of the ornament to rotate / stop at certain time intervals. Furthermore, when the user's fatigue level is greater than the first threshold, the control unit can also cause the movable part of the ornament to rotate at a slower speed than when the user's fatigue level is determined to be less than the first threshold.
[0276] The control unit can also control the display unit or decorations based on sound information acquired as biological information. For example, if the control unit determines that the conversation is lively based on the sound information, it can display a character with a laughing expression on the screen and rotate the movable parts of the decorations.
[0277] The display unit can also be a projection device for projecting images. The display unit can also be a rearview mirror inside a vehicle capable of displaying images.
[0278] The movement of the ornament based on signals from the touch sensor is not limited to rotation or up and down movement; it can be bending or straightening movements, or movement in directions other than up and down.
[0279] Decorations may also have display units, communication units, speakers, etc.
[0280] The decorative items can also be operated via the input devices on the seats or doors, navigation, etc.
[0281] The control unit can also notify the organism by flashing the lights of the ornaments. For example, the higher the user's fatigue level (or the worse their physical condition), the shorter the interval between flashes.
[0282] The control unit can also communicate information to the organism based on the intensity of the lighting. For example, the control unit can increase the intensity of the lighting as the user's fatigue level (or physical condition) increases.
[0283] Collision warnings can be issued via sound or light. For example, the control unit can turn the lighting red and issue a collision warning message via sound and display on the screen when a collision is predicted. Alternatively, the control unit can rotate a red-lit decorative item when a collision is predicted. In this case, the movement of the decorative item is more noticeable, making it easier for the user to notice.
[0284] When the decorative item protrudes upwards from the headrest, the control unit can also restrict the vertical movement of the movable part of the decorative item based on the angle of the seat back. For example, when the angle between the seat cushion and the seat back (i.e., the tilt angle) is less than a predetermined angle (i.e., when the seat back is upright), the control unit does not restrict the vertical movement of the movable part of the decorative item. When the tilt angle is greater than the predetermined angle (i.e., when the seat back is reclined), the control unit will not allow the movable part of the decorative item to move vertically, even if the conditions for vertical movement are met. Thus, by moving the movable part of the decorative item vertically, it is possible to prevent the movable part from hitting a person sitting in the back seat. Furthermore, when the tilt angle is greater than the predetermined angle, the control unit can also make the expression of the character in the picture an anxious expression.
[0285] The vehicle is not limited to automobiles, but can also be other vehicles, such as two-wheeled vehicles, trams, etc.
[0286] The following methods can be listed as examples of manufacturing methods for vehicle systems.
[0287] A method for manufacturing a vehicle system, the vehicle system comprising: an interior trim component disposed within a vehicle; a decorative trim component disposed on the interior trim component; an electric device for changing the shape of the decorative trim component; a sensor for acquiring biometric information of a user; and a control unit that, based on the biometric information acquired from the sensor, activates the electric device to change the shape of the decorative trim component, the method comprising: a step of installing the decorative trim component on the interior trim component; a step of installing the sensor at a location capable of detecting the user's biometric information; and a step of connecting the electric device and the sensor to the control unit.
[0288] [Sixth Implementation Method]
[0289] The sixth embodiment of the vehicle system will now be described with reference to the accompanying drawings.
[0290] like Figure 12 As shown, the vehicle system 101 includes a seat 110, a monitor M1 (an example of a display unit), a camera CM1 (an example of a collision detection unit), and a control unit CT1. The seat 110, monitor M1, and camera CM1 are disposed inside the vehicle, specifically in a position facing the passenger compartment. In this embodiment, the seat 110 is configured as a driver's seat or a front passenger seat.
[0291] Seat 110 includes a seat cushion 111, a seat back 112, and a headrest 113. The seat cushion 111, seat back 112, and headrest 113 each constitute the main body of the seat having a seating surface F1. The seating surface F1 is the surface that contacts and supports the user sitting in the seat 110.
[0292] The seat cushion 111, seat back 112, and headrest 113 each have a metal frame forming the skeleton, a padding covering the frame, and a cover material covering the padding. The padding may contain urethane foam, etc. The cover material may contain synthetic leather or fabric, etc.
[0293] The seat cushion 111 has: a base portion 111A disposed at the left and right center; and extension portions 111B disposed on the outer sides of both sides of the base portion 111A. The base portion 111A has a seating surface F1 that contacts and supports the user's buttocks and thighs from below. The extension portions 111B extend from the seating surface F1 of the base portion 111A toward the user side to support the sides of the user's thighs and buttocks.
[0294] Furthermore, the seat back 112 also includes: a base portion 112A, disposed at the center on the left and right sides; and an extension portion 112B, disposed on the outer sides of both sides of the base portion 112A. The base portion 112A has a seating surface F1 that contacts the user's back and supports the back from behind. The extension portion 112B extends from the seating surface F1 of the base portion 112A toward the user side to support the sides of the user's upper body.
[0295] The seat 110 also includes an electric tilting mechanism 121, multiple vibration devices 123, an electric sliding mechanism 130, and multiple speakers 150.
[0296] The electric tilting mechanism 121 is a mechanism that tilts the seat back 112. The electric tilting mechanism 121 includes a motor that operates by being powered by electricity.
[0297] The vibration device 123 is an electrically powered device that vibrates when energized, thereby causing only a portion of the surface of the seat 110 to reciprocate. Four vibration devices 123 are provided in the base portion 111A of the seat cushion 111, and one is provided in each of the left and right extension portions 111B. The four vibration devices 123 provided in the base portion 111A are arranged in a left-right arrangement, front-back.
[0298] Four vibration devices 123 are provided in the base portion 112A of the seat back 112, and one is provided in each of the left and right extension portions 112B. The four vibration devices 123 provided in the base portion 112A are arranged in a vertical arrangement as a group of vibration devices 123 arranged horizontally. Each vibration device 123 is, for example, embedded in the padding.
[0299] The electric sliding mechanism 130 is a mechanism that allows the seat 110 to slide in the fore-and-aft direction. Here, the seat 110 is movably supported on a slide rail (not shown) in the fore-and-aft direction. The electric sliding mechanism 130 includes a motor that operates by being energized.
[0300] The speaker 150 is a device that generates sound by being powered on. One speaker 150 is provided on each side of the upper part of the seat back 112. One speaker 150 is provided on each side of the headrest 113. The speaker 150 is, for example, embedded in the cushioning.
[0301] The seat 110 also includes a tilt switch 161, a slide switch 162, and a mode switching switch 163.
[0302] The tilt switch 161 is an operating unit for activating the electric tilt mechanism 121. The tilt switch 161 is capable of tilting in the forward / backward direction, for example. When tilted forward, the tilt switch 161 outputs a forward tilt command to the control unit CT1 to tilt the seat back 112 forward. When tilted backward, the tilt switch 161 outputs a backward tilt command to the control unit CT1.
[0303] The slide switch 162 is an operating unit for activating the electric sliding mechanism 130. The slide switch 162 is capable of sliding in the forward-backward direction, for example. When the slide switch 162 slides forward, it outputs a forward command to the control unit CT1 to move the seat 110 forward. When the slide switch 162 slides backward, it outputs a backward command to the control unit CT1 to move the seat 110 backward.
[0304] The mode switch 163 is used to switch the control unit CT1 between a first mode and a second mode. Here, the first mode is the mode in which the device linkage processing described later can be performed. The second mode is the mode in which the device linkage processing is not performed. The mode switch 163 is, for example, a push-button switch. Whenever the user presses the mode switch 163, it alternately switches between an ON and OFF state. In this embodiment, when the mode switch 163 is in the OFF state, the mode is the second mode; when the mode switch 163 is in the ON state, the mode is the first mode.
[0305] Monitor M1 has a screen M11 for displaying images (see reference). Figure 14 The image displayed on monitor M1 can be changed by control unit CT1. Monitor M1 can be configured, for example, on the dashboard below the rearview mirror.
[0306] Camera CM1 is a camera that takes pictures of the front of the vehicle. Camera CM1 is installed, for example, on the roof of the vehicle. The image information captured by camera CM1 is output to control unit CT1.
[0307] The control unit CT1 may include, for example, a CPU, RAM, ROM, input / output circuits, etc. The control unit CT1 may be installed in the seat 110 or in a component other than the seat 110.
[0308] The control unit CT1 is connected to the monitor M1, various switches (161-163), the electric tilting mechanism 121, each vibration device 123, the electric sliding mechanism 130, and each speaker 150. The control unit CT1 can make each vibration device 123 and each speaker 150 work independently.
[0309] The control unit CT1 has the following functions: it supports the driver's driving operations by providing auxiliary processing to accelerate or decelerate the vehicle or change the steering angle based on the vehicle's surrounding environment. Specifically, for example, if the control unit CT1 determines that there is a curve in the road based on information from the camera CM1, it controls the braking device to decelerate the vehicle before it approaches the curve.
[0310] Based on information from camera CM1, control unit CT1 accelerates the vehicle by controlling the engine when the distance between the vehicle and the vehicle in front is greater than a preset distance. Control unit CT1 also controls the steering mechanism to steer the vehicle left or right based on information from camera CM1, preventing the vehicle from deviating from its lane.
[0311] When performing auxiliary processing, the control unit CT1 performs equipment linkage processing to activate the vibration device 123 based on the movement of the vehicle operated through the auxiliary processing. Specifically, the control unit CT1 performs equipment linkage processing when the magnitude of the acceleration or steering angle changed through the auxiliary processing exceeds a predetermined threshold. More specifically, the control unit CT1 performs equipment linkage processing when the magnitude of the acceleration changed through the auxiliary processing exceeds an acceleration threshold, or when the magnitude of the steering angle changed through the auxiliary processing exceeds a steering angle threshold.
[0312] like Figure 13 As shown in (a), the control unit CT1 selects the vibration device 123 to operate from multiple options based on whether the driving operation supported by the auxiliary processing is acceleration, deceleration, right turn, or left turn. Specifically, when the driving operation supported by the auxiliary processing is acceleration or deceleration, the control unit CT1 selects and operates the vibration device 123 located at the left or right center of the seat cushion 111, specifically at the base portion 111A. Furthermore, the vibration device 123 to operate only needs to be at least one of the four vibration devices 123 located at the base portion 111A.
[0313] When the driving operation supported by the auxiliary processing is a right turn, the control unit CT1 selects and operates the vibration device 123 located on the right-side extensions 111B and 112B. Furthermore, the vibration device to be operated only needs to be at least one of the two vibration devices 123 located on the right-side extensions 111B and 112B.
[0314] When the driving operation supported by the auxiliary processing is a left turn, the control unit CT1 selects and operates the vibration device 123 located on the left side of the protrusions 111B and 112B. Furthermore, the vibration device to be operated is only one of the two vibration devices 123 located on the left side of the protrusions 111B and 112B.
[0315] The control unit CT1 changes the operating mode of the vibration device based on the acceleration or steering angle changed through auxiliary processing. Specifically, when the acceleration is changed to the positive side through auxiliary processing, that is, when the vehicle is accelerated, the control unit CT1 causes the vibration device 123 to... Figure 13 (b) The operation mode is intermittent. In this embodiment, the operation mode is set such that the working time of the intermittently operating vibration device gradually increases, but each working time can be fixed or set to gradually decrease.
[0316] When the control unit CT1 changes the acceleration to the negative side through auxiliary processing, that is, when the vehicle is decelerated, it causes the vibration device 123 to... Figure 13 (c) The operation continues in the same mode of motion. Furthermore, when the control unit CT1 changes the steering angle, for example, to the positive or negative side, to make the vehicle turn to the right or left, it also causes the vibration device 123 to... Figure 13 The operation continues in the mode shown in (c). Furthermore, the positive and negative sides of the steering angle (0 when the vehicle is traveling straight), as well as the right and left sides of the steering, can be arbitrarily set.
[0317] The control unit CT1 has the function of changing the intensity of the vibration of the vibration device 123 based on the magnitude of the acceleration changed through auxiliary processing. In this embodiment, the greater the magnitude of the acceleration changed through auxiliary processing, the greater the intensity of the vibration of the vibration device 123 caused by the control unit CT1. Furthermore, as a vibration device capable of changing the intensity of vibration, for example, a vibration device that changes the vibration frequency and amplitude to change the intensity of vibration can be used.
[0318] The control unit CT1 has the following function: based on the steering angle changed through auxiliary processing, it outputs sound from one of the left and right speakers 150. In this embodiment, as... Figure 13 As shown in (a), when the control unit CT1 turns the vehicle to the right by changing the steering angle, for example, to the positive side, through auxiliary processing, it outputs sound from the right-side speaker 150. The speaker 150 that outputs the sound can be at least one of the two right-side speakers 150 located on the seat back 112 and the headrest 113.
[0319] Furthermore, when the control unit CT1 turns the vehicle to the left by changing the steering angle, for example, to the negative side, through auxiliary processing, it outputs sound from the left-side speaker 150. The speaker 150 used to output the sound can be at least one of the two left-side speakers 150 located on the seat back 112 and headrest 113.
[0320] like Figure 14As shown, the control unit CT1 has the following functions: displaying an image of a chair and an image of a cat as an example on the screen M11 of the monitor M1. During device linkage processing, the control unit CT1 coordinates with the movement of the vibration device 123 to move the cat on the screen M11.
[0321] Specifically, when the vehicle is accelerated through auxiliary processing, such as Figure 14 As shown, the control unit CT1 displays a dynamic image of a cat running on a seat, along with images of text indicating acceleration, such as "Accelerate, meow~", on the screen M11. Furthermore, in this case, the control unit CT1 outputs sounds such as "Accelerate, meow~" from the speakers 150 on both sides.
[0322] When the vehicle is slowed down through auxiliary processing, such as Figure 15 As shown, the control unit CT1 displays a dynamic image of a cat trying to stop running by pushing off the ground with its front paws, along with text indicating deceleration such as "Slow down, meow~" on the screen M11. Furthermore, in this situation, the control unit CT1 outputs sounds such as "Slow down, meow~" from the speakers 150 on both sides.
[0323] When a vehicle turns right using auxiliary processing, such as Figure 16 As shown, the control unit CT1 displays a dynamic image of a cat walking to the right on a seat, along with images of text indicating a turn such as "Turn right, meow~" on the screen M11. In this case, the control unit CT1 outputs sounds such as "Turn right, meow~" from the speaker 150 on the right side.
[0324] The auxiliary processing makes the display of the image when the vehicle turns left simply... Figure 16 The cat is facing left, and the "right" in the image of the text is changed to "left," so the illustration is omitted. Additionally, in this case, the control unit CT1 outputs a sound such as "Turn left, meow~" from the speaker 150 on the left side.
[0325] In addition, the control unit CT1 has a feature based on data from... Figure 12 The camera CM1 shown has the function of predicting vehicle collisions based on information. The control unit CT1 has the function of not performing equipment linkage processing when a vehicle collision is predicted. For example, if the control unit CT1 predicts a vehicle collision in the first mode, it switches the mode to the second mode without performing equipment linkage processing.
[0326] Next, the operation of the control unit CT1 will be explained in detail.
[0327] Control unit CT1 executes repeatedly Figure 17 The processing shown. In Figure 17In the process, the control unit CT1 first determines whether the mode switching switch 163 is turned on (S101). If it is determined in step S101 that the mode switching switch 163 is not turned on (No), the control unit CT1 sets the mode to the second mode (S112) and ends the process.
[0328] If it is determined in step S101 that the mode switching switch 163 is turned on (Yes), the control unit CT1 determines whether there is a possibility of a vehicle collision based on the information from the camera CM1 (S102). If it is determined in step S102 that there is a possibility of a vehicle collision (Yes), the control unit CT1 switches the mode to the second mode (S112) and ends the process.
[0329] If it is determined in step S102 that there is no possibility of a vehicle collision (No), the control unit CT1 switches to the first mode (S103). After step S103, the control unit CT1 acquires information from the camera CM1 (S104).
[0330] After step S104, the control unit CT1 determines whether auxiliary processing is needed based on information from the camera CM1 (S105). If it is determined in step S105 that auxiliary processing is not needed (No), the control unit CT1 ends the process.
[0331] If, in step S105, it is determined that auxiliary processing is required (Yes), the control unit CT1 determines whether the magnitude of the acceleration changed by the auxiliary processing is greater than an acceleration threshold, or whether the magnitude of the steering angle changed by the auxiliary processing is greater than a steering angle threshold (S106). If, in step S106, it is determined that the magnitude of the acceleration is below the acceleration threshold and the magnitude of the steering angle is below the steering angle threshold (No), the control unit CT1 does not perform equipment linkage processing (S107-S110), but instead executes auxiliary processing (S111) and ends this processing.
[0332] If, in step S106, it is determined that the magnitude of the acceleration is greater than the acceleration threshold or the magnitude of the steering angle is greater than the steering angle threshold (Yes), the control unit CT1 determines whether the object supported by the auxiliary processing is acceleration or deceleration (S107). If, in step S107, it is determined that the object supported by the auxiliary processing is acceleration or deceleration (Yes), the greater the magnitude of the acceleration changed in the auxiliary processing, the greater the intensity of the vibration of the vibration device 123 is set by the control unit CT1 (S108).
[0333] If the condition is "No" after step S108 or in step S107, the control unit CT1 activates the vibration device 123 and the speaker 150 corresponding to the support object of the auxiliary processing (S109). After step S109, the control unit CT1 displays the image corresponding to the support object of the auxiliary processing on screen M11 (S110). After step S110, the control unit CT1 executes the auxiliary processing (S111) and ends the current processing.
[0334] Next, a specific example of the operation of the control unit CT1 will be explained.
[0335] In the first mode, when the control unit CT1 accelerates the vehicle through auxiliary processing, such as Figure 13 As shown in (a) and (b), the control unit CT1 causes the vibration device 123 at the center of the left and right sides of the seat cushion 111 to operate intermittently, and... Figure 14 The dynamic image shown is displayed on screen M11. As a result, the seat cushion 111's seating surface F1 vibrates slightly in conjunction with the cat's running motion on screen M11, so the user can feel the cat's running motion through the seat 110 and thus understand when the vehicle will accelerate.
[0336] Furthermore, in the first mode state, when the control unit CT1 decelerates the vehicle through auxiliary processing, such as Figure 13 As shown in (a) and (c), the control unit CT1 causes the vibration device 123 at the center of the left and right sides of the seat cushion 111 to vibrate continuously, and... Figure 15 The dynamic image shown is displayed on screen M11. Thus, in conjunction with the cat's front paw pushing off the ground on screen M11 (an action of trying to brake and stop with the front paws), the seating surface F1 of the seat cushion 111 vibrates continuously. Therefore, the user can virtually experience the force that the cat experiences from the ground (the upper surface of the seat) through its front paws, thereby understanding the situation where the vehicle needs to decelerate.
[0337] Additionally, in the first mode, when the control unit CT1 causes the vehicle to turn right through auxiliary processing, such as Figure 13 As shown in (a), the control unit CT1 causes the vibration device 123 of the protrusions 111B and 112B on the right side to vibrate, and outputs sound from the speaker 150 on the right side, and... Figure 16 The animated image shown is displayed on screen M11. As a result, in conjunction with the cat's movement to the right on screen M11, the right-side protrusions 111B and 112B vibrate and output sound from the right-side speaker 150. Thus, the user can feel the cat's movement to the right through the seat 110, thereby knowing when the vehicle will turn right.
[0338] Based on this embodiment, the following effects can be obtained.
[0339] Since the vibration device 123 operates according to the content of the auxiliary processing, the detailed content of the auxiliary processing can be transmitted to the user.
[0340] When the magnitude of the acceleration or steering angle changed through auxiliary processing is below a specified threshold, since no equipment linkage processing is performed, the sense of confusion can be suppressed and the comfort can be improved.
[0341] Since the operating mode of the vibration device 123 is changed based on the acceleration or steering angle that is altered through auxiliary processing, the detailed information of the auxiliary processing can be conveyed to the user through the operating mode of the vibration device 123.
[0342] Depending on the driving operation supported by the auxiliary processing, the location of the vibrating device 123 to be operated varies, so the user can understand the content of the auxiliary processing in detail according to the location of the vibrating device 123 to be operated.
[0343] Since the magnitude of the acceleration altered through auxiliary processing is greater, resulting in greater vibration intensity, users can intuitively understand the magnitude of the acceleration by observing the intensity of the vibration from the seating surface F1.
[0344] Because the cat on screen M11 moves in coordination with the movement of the vibration device 123 during the device linkage process, the user can feel the cat undergoing auxiliary processing through the movement of the vibration device 123, thus making the user feel as if the vehicle and the cat are integrated into one.
[0345] Since sound is output from one of the left and right speakers 150 based on the steering angle changed through auxiliary processing, the user can understand the vehicle turning through the auxiliary processing by hearing.
[0346] In situations where there is a possibility of a vehicle collision, safety can be improved by not implementing equipment linkage processing.
[0347] [Seventh Implementation Method]
[0348] Next, the seventh embodiment will be described in detail with reference to the accompanying drawings. Furthermore, since this embodiment modifies a portion of the vehicle system structure of the sixth embodiment, components identical to those in the sixth embodiment will be labeled with the same reference numerals, and their descriptions will be omitted.
[0349] The vehicle system 401 of the seventh embodiment has a seat 410 with a slightly different structure from that of the sixth embodiment. The seat 410 has air chambers 430A, 430B, and 430C to replace the vibration device 123 of the sixth embodiment as an electric device.
[0350] The air chamber 430A includes an inflatable / contractable bag 431, and an air pump (not shown) and tubing (to allow air to flow into the bag 431). The air pump, which is powered by electricity, is capable of supplying air into or drawing air out of the bag 431. The tubing connects the bag 431 to the air pump.
[0351] Bag 431 is embedded in the padding. In addition, the air pump is, for example, fixed to the frame of seat 110.
[0352] The pocket 431 of air chamber 430A is located at the lower part of the seat back 112, specifically at a position corresponding to the waist of the user sitting in seat 110. Air chambers 430B and 430C have the same structure as air chamber 430A, but the pocket 431 of air chambers 430B and 430C is smaller than that of air chamber 430A.
[0353] The bags 431 of air chambers 430B and 430C are arranged side-by-side above air chamber 430A, specifically arranged side-by-side in a position corresponding to the back of the user sitting in seat 110. Air chambers 430A to 430C can expand or contract according to a reference size.
[0354] like Figure 19 As shown, the control unit CT1 selects the air chamber to operate from multiple options based on whether the driving operation supported by the auxiliary processing is acceleration, deceleration, right turn, or left turn. Specifically, when the driving operation supported by the auxiliary processing is acceleration, the control unit CT1 inflates the air chamber 430A located below the seat back 112 to a size larger than a reference.
[0355] When the driving operation supported by the auxiliary processing is deceleration, the control unit CT1 contracts the air chamber 430A located below the seat back 112 to a smaller size than the reference. When the driving operation supported by the auxiliary processing is a right turn, the control unit CT1 expands the air chamber 430B located at the upper right of the seat back 112 to a larger size than the reference. When the driving operation supported by the auxiliary processing is a left turn, the control unit CT1 expands the air chamber 430C located at the upper left of the seat back 112 to a larger size than the reference.
[0356] That is, the control unit CT1 expands one of the left and right air chambers based on the steering angle changed through auxiliary processing.
[0357] Control Unit CT1 Execution Figure 20 The processing. Figure 20 In addition to having Figure 17 In addition to steps S101 to S106 and steps S110 to S113 in the processing, a new step S131 is also included. Furthermore, in the seventh embodiment, the control unit CT1 controls the speaker 150 using the same method as in the sixth embodiment.
[0358] If, in step S106, the control unit CT1 determines that the magnitude of the acceleration is greater than an acceleration threshold or the magnitude of the steering angle is greater than a steering angle threshold (Yes), it activates the air chamber and speaker 150 corresponding to the support object being assisted in the processing (S131). After step S131, the control unit CT1 displays the image corresponding to the support object being assisted in the processing on the screen M11 (S110).
[0359] Furthermore, in the seventh embodiment, the image used when the vehicle accelerates or decelerates is set to be the same as in the sixth embodiment. Figure 14 or Figure 15 The image, but set the image when the vehicle is turning to... Figure 21 (a) Such an image. When the control unit CT1 causes the vehicle to turn right via auxiliary processing, it will... Figure 21 An image of a cat attempting to move along a bend, as shown in (a), is displayed on screen M11, and as... Figure 21 (b) shows the expansion of the right-side air chamber 430B.
[0360] Thus, when the vehicle turns right, the right-side air chamber 430B expands, and the user sitting in the seat 110 can understand the vehicle turning right through the pressure from the right side of the seat back 112.
[0361] Furthermore, the control unit CT1 can also adjust the inflow rate of air from the air pump into the bag 431 based on the steering angle changed through auxiliary processing. Specifically, the larger the steering angle changed through auxiliary processing, the greater the inflow rate of air into the bag 431 caused by the control unit CT1. Accordingly, the user can understand the size of the changed steering angle by the amount of bag expansion in the air chamber.
[0362] The seat may also have both a vibration device and an air chamber. The control unit may also activate at least one of the vibration device and the air chamber during equipment linkage processing.
[0363] In cases where deceleration is achieved through auxiliary processing, the vibration device of the seat back can also be activated after the vibration device of the seat cushion has been activated.
[0364] When turning right or left with the assistance of the system, multiple vibration devices arranged on the left and right sides of the seat back can vibrate in a sequence from right to left or from left to right while the character changes direction, thereby causing the vibration position to move in a flowing manner.
[0365] The vibration velocity or vibration mode can also be changed based on the magnitude of the acceleration, which is altered through auxiliary processing.
[0366] Alternatively, the vibrating device can be operated by accelerating or decelerating through auxiliary processing, or the air chamber can be operated by turning right or left.
[0367] Driving operations supported by auxiliary processing, as well as the electric equipment to be operated, can also be handled as follows.
[0368] Acceleration: Vibration device for buffer pads
[0369] Deceleration: Vibration device for seat back
[0370] Turning: Vibrating device with either the left or right extension.
[0371] In the aforementioned situation, the protruding part of the seat back or the protruding part of the seat cushion may also vibrate in conjunction with acceleration or deceleration.
[0372] Driving operations supported by auxiliary processing, as well as the electric equipment to be operated, can also be handled as follows.
[0373] Acceleration: The vibrating device located on the upper part of the seat back vibrates at a first intensity, and the vibrating device located on the lower part of the seat back vibrates at a second intensity less than the first intensity.
[0374] Deceleration: The vibrating device located on the upper part of the seat back vibrates at a second intensity, and the vibrating device located on the lower part of the seat back vibrates at a first intensity.
[0375] Turning: causing either of the vibrating devices located on the left or right side of the seat back to vibrate at the first intensity.
[0376] Furthermore, when the vibration devices arranged left and right are located on the upper part of the seat back, for example, during acceleration, either the left or right vibration device on the upper part of the seat back can vibrate at a first intensity. Additionally, when accelerating the vehicle and turning right, the vibration device on the upper right side of the seat back can vibrate at a first intensity (high), followed by the vibration device on the upper left side of the seat back vibrating at a second intensity (medium), and the vibration device on the lower part of the seat back vibrating at a third intensity (low) less than the second intensity.
[0377] Furthermore, when turning the vehicle to the right, the following process can be repeated: after the left vibrating device of the two vibrating devices arranged on the left and right vibrates at the second intensity (small), the right vibrating device vibrates at the first intensity (large). Conversely, when turning the vehicle to the left, the following process can be repeated: after the right vibrating device vibrates at the second intensity (small), the left vibrating device vibrates at the first intensity (large).
[0378] Furthermore, when accelerating the vehicle, the vibration device at the front end of the seat cushion can vibrate at a second intensity (small), and the vibration device at the rear end of the seat cushion can vibrate at a first intensity (large). Conversely, when decelerating the vehicle, the vibration device at the front end of the seat cushion can vibrate at a first intensity (large), and the vibration device at the rear end of the seat cushion can vibrate at a second intensity (small).
[0379] The character display can simultaneously show turning and acceleration / deceleration, or it can display the larger change in acceleration or steering angle. For example, it could display a change in steering angle of 5 degrees and an acceleration change of 7 km / h. 2 Then the character corresponding to acceleration and deceleration will be displayed with priority. If the change in steering angle is 7 degrees and the change in acceleration is 5 km / h... 2 This will prioritize the display of the character corresponding to the turn.
[0380] Air chambers can also be installed in the base of the seat cushion, the left and right extensions, the left and right extensions of the seat back, and the headrest. Vibration devices can also be installed in the headrest.
[0381] Vibration equipment can also be any equipment that has a motor and wiring harness that emits vibration, or an eccentric motor, or a linear motor, etc.
[0382] The display unit can be installed in any location, such as the instrument panel, center console, steering mechanism, gauges, seat backs, door sides, or trim. Alternatively, it can be a projection device for projected images. It can also be a portable terminal such as a smartphone or tablet held by the occupant.
[0383] The character can be an animal other than a cat, a living being such as a plant, or a personified version of an object or creature. The character can be pre-defined, for example, it can be an image of a occupant transformed.
[0384] The vehicle is not limited to automobiles, but can also be other vehicles, such as two-wheeled vehicles, trams, etc.
[0385] The collision detection unit can also be a distance sensor that detects the distance between the vehicle and the vehicle in front.
[0386] The following methods can be listed as examples of manufacturing methods for vehicle systems.
[0387] A method for manufacturing a vehicle system, the vehicle system supporting driver operation through auxiliary processing that accelerates, decelerates, or changes steering angle based on the vehicle's surrounding environment, and comprising: a seat for a user to sit on; an electric device that moves a portion of the seat surface and includes a vibration device and / or an air chamber; and a control unit that, when executing the auxiliary processing, performs device linkage processing to operate the electric device based on the actions of the vehicle operating through the auxiliary processing, the vehicle system manufacturing method comprising: a step of installing the electric device on the seat; a step of installing the seat and the control unit on the vehicle; and a step of connecting the electric device to the control unit.
[0388] [Eighth Implementation Method]
[0389] Hereinafter, the eighth embodiment of the vehicle system will be described with reference to the accompanying drawings.
[0390] like Figure 22 As shown, the vehicle system 201 includes a vehicle frame CF, a suspension device SP (an example of an impact absorption component), a monitor M2 (an example of a display unit), an operating unit SW, a seat 210 for a user to sit in, and a control unit CT2. The suspension device SP, monitor M2, seat 210, and control unit 100 are supported on the vehicle frame CF.
[0391] The suspension device SP is a suspension system that absorbs impacts from the road surface and is positioned between the road surface and the vehicle frame CF. Specifically, the suspension device SP is positioned between the tire T and the vehicle frame CF. The suspension device SP can vary its impact absorption rate by adjusting air pressure, magnetic fluid, hydraulic pressure, etc. For example, the suspension system described in Japanese Patent Application Publication No. 2000-280806 can be used as a suspension device SP capable of varying impact absorption rate. The variation in impact absorption rate is achieved by adjusting the damping force of the suspension device SP.
[0392] Monitor M2 has a screen M21 for displaying images (see reference). Figure 25 The image displayed on monitor M2 can be changed by control unit CT2. Monitor M2 can be configured, for example, on the dashboard below the rearview mirror.
[0393] like Figure 23 As shown, the operating unit SW is operated by the occupant of seat 210 and is used to change the shock absorption of the suspension device SP. The operating unit SW includes a first switch SW1, a second switch SW2, and a third switch SW3.
[0394] Furthermore, in the following explanation, the shock absorption capacity of the suspension system SP will also be referred to as the "stiffness of the suspension system." The relationship between the stiffness of the suspension system and the shock absorption capacity is that the greater the stiffness of the suspension system, the smaller the shock absorption capacity. Additionally, the relationship between damping force and the stiffness of the suspension system is that the greater the damping force, the greater the stiffness of the suspension system.
[0395] The first switch SW1 is used to set the stiffness of the suspension system below a first specified value. For example, the first switch SW1 can be configured to switch the vehicle's driving mode to a comfort mode that prioritizes ride comfort.
[0396] The second switch SW2 is used to adjust the stiffness of the suspension system to be greater than a first specified value and less than a second specified value. For example, the second switch SW2 can be configured to switch the vehicle's drive mode to standard mode.
[0397] The third switch SW3 is used to make the suspension system stiffness greater than the second specified value. For example, the third switch SW3 can be configured to switch the vehicle's drive mode to sport mode.
[0398] Furthermore, the stiffness of the suspension system can be changed by the control unit CT2, or by a control unit different from CT2. In this embodiment, the control unit different from CT2 changes the stiffness of the suspension system based on information from the operation unit SW.
[0399] The seat 210 includes a seat cushion 211, a seat back 212, and a headrest 213. The seat cushion 211, seat back 212, and headrest 213 respectively constitute the seat body 210A having a seating surface F2 that supports the seated person.
[0400] The seat cushion 211 has: a base portion 211A disposed at the left and right center; and extension portions 211B disposed on the outer sides of both sides of the base portion 211A. The base portion 211A has a seating surface F2 and contacts and supports the user's buttocks and thighs from below. The extension portions 211B extend from the seating surface F1 of the base portion 211A toward the seated person to support the sides of the user's thighs and buttocks.
[0401] Furthermore, the seat back 212 also includes: a base portion 212A, disposed at the center on the left and right sides; and extension portions 212B, disposed on the outer sides of both sides of the base portion 212A. The base portion 212A has a seating surface F2 that contacts the user's back and supports the back from behind. The extension portions 212B extend from the seating surface F2 of the base portion 212A toward the user side to support the sides of the user's upper body.
[0402] The extensions 211B and 212B have inner surfaces F3 that support the occupant from the left and right sides. The seating surface F2 and the inner surfaces F3 constitute the occupant-side surface of the seat 210.
[0403] like Figure 24 As shown, the seat cushion 211 includes a frame FL, a pad PD, and a cover SK. The frame FL may contain metal or the like and supports the pad PD. The pad PD may contain a cushioning material such as urethane foam. The cover SK may contain synthetic leather or fabric or the like and covers the pad PD. Similarly, the seat backrest 112 and headrest 113 also include a frame, a pad, and a cover.
[0404] Seat 210 also has an air chamber 222, which is an example of an electric device (see also...). Figure 23 ), vibration device 223, and sensor 224. For example Figure 23 As shown, air chamber 222 (specifically, bag 222A described later) is provided in one of each of the four protrusions 211B and 212B. The structure around the air chamber 222 in each protrusion 211B and 212B is generally the same, therefore, the following description refers to... Figure 24 The structure of the right-side protrusion 211B of the seat cushion 211 will be used as an example for explanation. The structures of other protrusions 211B and 212B will be omitted from the explanation.
[0405] like Figure 24 As shown in (a) and (b), the air chamber 222 is an electrically powered device that moves only a portion of the inner surface F3 of the protrusion 211B. The air chamber 222 includes an inflatable / contractable bag 222A, and a pump and tubing (not shown). The pump, which is energized, functions to introduce air into or draw air out of the bag 222A. The tubing connects the bag 222A to the pump.
[0406] The bag 222A is located between the padding PD and the frame FL. Alternatively, the bag 222A may be embedded within the padding PD. Furthermore, the pump may be fixed, for example, to the frame FL of the seat 210.
[0407] Bag 222A can be transformed into Figure 24 (a) The first shape shown Figure 24 (a) shows a second shape that expands beyond the first shape, and a third shape that expands beyond the second shape (illustration omitted). When bag 222A is in the first shape, the inner side F3 is located... Figure 24 (a) shows the first position. When bag 222A becomes the second shape, the inner side F3 is located at... Figure 24 (b) shows the second position, which is closer to the seated person than the first position. When bag 222A becomes the third shape, the inner side F3 is located in the third position, which is closer to the seated person than the second position (illustration omitted).
[0408] The vibration device 223 is a device that vibrates by means of electricity. Two vibration devices 223 are provided in the protrusion 211B. In addition, it is sufficient that at least one vibration device 223 is provided in the protrusion 211B.
[0409] Two vibrating devices 223 are arranged at intervals along the left-right direction. In the following description, the vibrating device 223 on the inner side in the left-right direction is also referred to as "first vibrating device 223A", and the vibrating device 223 on the outer side in the left-right direction is also referred to as "second vibrating device 223B". Alternatively, contrary to this embodiment, the vibrating device 223 on the outer side in the left-right direction may be referred to as the first vibrating device, and the vibrating device 223 on the inner side in the left-right direction may be referred to as the second vibrating device.
[0410] The distance from the first vibration device 223A to the outer skin SK is approximately equal to the distance from the second vibration device 223B to the outer skin SK. Each vibration device 223 is located between the sensor 224 and the bag 222A. Each vibration device 223 is embedded, for example, in the padding PD.
[0411] Sensor 224 is a sensor that detects contact between the inner surface F3 and the seated person. In this embodiment, sensor 224 is a pressure sensor. Sensor 224 is located between the skin SK and the padding PD.
[0412] like Figure 23 As shown, the control unit CT2 is configured to include, for example, a CPU, RAM, ROM, input / output circuits, etc. The control unit CT2 may be installed in the seat 210 or in a component other than the seat 210.
[0413] Control unit CT2 and monitor M2, operation unit SW, air chamber 222, vibration device 223 and sensor 224 (see reference) Figure 24 The control unit CT2 can independently operate multiple air chambers 222 and multiple vibration devices 223.
[0414] The control unit CT2 has the following functions: it determines the stiffness of the suspension system based on information from the operation unit SW, and operates the air chamber 222 based on the stiffness (impact absorption) of the suspension system. Specifically, the control unit CT2 changes the size of the bag 222A in the air chamber 222 based on the stiffness of the suspension system.
[0415] In detail, when the stiffness of the suspension system is below a first predetermined value, i.e., when the damping force is less than a predetermined value, the control unit CT2 positions the inner surfaces F3 of each of the four protrusions 211B and 212B in a first position by aligning the pockets 222A of each air chamber 222 into a first shape. When the stiffness of the suspension system is greater than the first predetermined value but less than a second predetermined value, i.e., when the damping force is greater than a predetermined value, the control unit CT2 positions the inner surfaces F3 in a second position by aligning the pockets 222A of each air chamber 222 into a second shape. When the stiffness of the suspension system is greater than the second predetermined value, the control unit CT2 positions the inner surfaces F3 in a third position by aligning the pockets 222A of each air chamber 222 into a third shape.
[0416] Furthermore, regarding the shape change of the air chamber 222 corresponding to the stiffness of the suspension system, it is sufficient to perform the change on at least one of the four air chambers 222 located on the left and right sides of the seat cushion 211 and the left and right sides of the seat back 212. For example, the control unit CT2 may change the shape of only the air chambers 222 on the left and right sides of the seat cushion 211 according to the stiffness of the suspension system, or it may change the shape of only the air chambers 222 on the left and right sides of the seat back 212 according to the stiffness of the suspension system.
[0417] The control unit CT2 has the function of activating the vibration device 223 when the inner side F3 moves towards the seated person through the air chamber 222. The control unit CT2 also has the function of determining the size of the air chamber 222 based on information obtained from the sensor 224 when the inner side F3 moves towards the seated person through the air chamber 222. Furthermore, the control unit CT2 has the function of activating the vibration device 223 when the pressure value obtained from the sensor 224 exceeds a threshold.
[0418] like Figure 25 As shown, the control unit CT2 has the function of displaying images of the suspension system, the cat's role, and the seat on screen M21 of the monitor M2. When the impact absorption rate changes, the control unit CT2 displays an image of the cat with the changed impact absorption rate on screen M21.
[0419] For example, when the stiffness of the suspension system is below a first predetermined value, the control unit CT2 displays a dynamic image of the cat massage suspension system and an image with text such as "Relax, meow~". Additionally, at this time, the control unit CT2 displays a dynamic image of a cat pressing down on the seat extensions from the left and right sides.
[0420] Furthermore, if the stiffness of the suspension system is greater than the first specified value but less than the second specified value, or greater than the second specified value, it is sufficient to display dynamic images of the cat performing a show corresponding to the stiffness of the suspension system or the state of the seat.
[0421] Next, the operation of the control unit CT2 will be explained in detail.
[0422] Control unit CT2 repeatedly executes Figure 26 The processing shown.
[0423] exist Figure 26 In the process, the control unit CT2 first determines whether the vehicle's drive mode has changed based on the signal from the operation unit SW, and thereby determines whether the stiffness of the suspension system has changed (S201). If it is determined in step S201 that the stiffness has not changed (No), the control unit CT2 ends the process.
[0424] If, in step S201, it is determined that the stiffness has changed (Yes), the control unit CT2 determines whether the stiffness of the suspension system is below a first predetermined value by determining whether the first switch SW1 has been selected (S202). If, in step S202, it is determined that the stiffness is below the first predetermined value (Yes), the control unit CT2 displays an image corresponding to the stiffness of the suspension system on screen M21 (S203). Furthermore, in step S203, the control unit CT2 also displays an image corresponding to the seat state that changes through the subsequent steps S204 to S206 on screen M21.
[0425] After step S203, the control unit CT2 causes each air chamber 222 to contract (S204). After step S204, the control unit CT2 determines whether the pressure value P obtained from the sensor 224 is less than the first threshold Pth1 (S205).
[0426] If it is determined in step S205 that P is not < Pth1 (No), the control unit CT2 returns to the processing in step S204. If it is determined in step S205 that P < Pth1 (Yes), the control unit CT2 stops the contraction of the air chamber 222 (S206) and ends the processing.
[0427] If, in step S202, it is determined that the stiffness of the suspension system is not below the first predetermined value (No), the control unit CT2 determines whether the stiffness of the suspension system is below the second predetermined value by determining whether the second switch SW2 has been selected (S207). If, in step S207, it is determined that the stiffness of the suspension system is below the second predetermined value (Yes), the control unit CT2 displays an image corresponding to the stiffness of the suspension system on screen M21 (S208). Furthermore, in step S208, the control unit CT2 also displays an image corresponding to the seat state that changes through the subsequent steps S209 to S212 on screen M21.
[0428] After step S208, the control unit CT2 expands each air chamber 222 (S209). After step S209, the control unit CT2 determines whether the pressure value P obtained from the sensor 224 is greater than the second threshold Pth2 (S210). Here, the second threshold Pth2 is greater than the first threshold Pth1.
[0429] If it is determined in step S210 that P > Pth2 (No), the control unit CT2 returns to the process of step S209. If it is determined in step S210 that P > Pth2 (Yes), the control unit CT2 stops the expansion of the air chamber 222 (S211). After step S211, the control unit CT2 ends this process after the first vibration device 223A has been operating for a predetermined time (S212).
[0430] If, in step S207, it is determined that the stiffness of the suspension system is not below the second predetermined value (No), the control unit CT2 will display an image corresponding to the stiffness of the suspension system on screen M21 (S213). Furthermore, in step S213, the control unit CT2 will also display an image corresponding to the state of the seat that changes through the following steps S214 to S217 on screen M21.
[0431] After step S213, the control unit CT2 expands each air chamber 222 (S214). After step S214, the control unit CT2 determines whether the pressure value P obtained from the sensor 224 is greater than the third threshold Pth3 (S215). Here, the third threshold Pth3 is greater than the second threshold Pth2.
[0432] If it is determined in step S215 that P > Pth3 (No), the control unit CT2 returns to the process of step S214. If it is determined in step S215 that P > Pth3 (Yes), the control unit CT2 stops the expansion of the air chamber 222 (S216). After step S216, the control unit CT2 ends this process after the first vibration device 223A and the second vibration device 223B have been operating for a predetermined time (S217).
[0433] Next, a specific example of the operation of the control unit CT2 will be explained.
[0434] like Figure 23 As shown, when the vehicle's drive mode is in standard mode, and the occupant of seat 210 presses the first switch SW1 to switch the drive mode from standard mode to comfort mode, the suspension system stiffness falls below a first predetermined value, and the air chambers 222 of the four extensions 211B and 212B retract. Additionally, at this time, the display on screen M21 shows... Figure 25 The image shown.
[0435] Therefore, the occupant can feel the suspension system softening through the cat on screen M21, thus enhancing the entertainment experience. In addition, the occupant can feel the extensions 211B and 212B softening through the contraction of each air chamber 222, thus feeling the suspension system softening through the softness of the seat 210.
[0436] Furthermore, when the vehicle's driving mode is switched from Comfort mode to Standard mode, the air chambers 222 of the four extensions 211B and 212B expand, and the first vibration device 223A vibrates. As a result, in Standard mode, where the suspension system is stiffer than Comfort mode, the occupant can feel the stability of the seat 210, and through the vibration of only the first vibration device 223A, the occupant can feel that the suspension system is of medium stiffness.
[0437] Furthermore, when the vehicle's driving mode is switched from Standard Mode to Sport Mode, the air chambers 222 of the four extensions 211B and 212B expand further, and both the first vibration device 223A and the second vibration device 223B vibrate. As a result, in Sport Mode, where the suspension system is stiffer than in Standard Mode, the occupant can further feel the stability of the seat 210, and through the vibration of the two vibration devices 223, can feel the greater stiffness of the suspension system.
[0438] Based on this embodiment, the following effects can be obtained.
[0439] Since the air chamber 222 operates based on the shock absorption capacity, the occupant side of the seat 210 can be shaped to adapt to the impact, thereby achieving shock absorption retention.
[0440] When the suspension system is stiff (low shock absorption), by increasing the size of the air chamber 222, the seat 210 becomes stiffer, and the impact from the road surface is more easily transmitted to the occupant, so the occupant can understand the state of the suspension system.
[0441] When the suspension system is stiff, by increasing the size of the air chamber 222, the inner surfaces F3 of the left and right protrusions 211B and 212B move towards the user side and come into contact with the user, thus improving retention.
[0442] By displaying an image of a cat changing its shock absorption on monitor M2 via the control unit CT2, occupants are given the illusion that the cat is changing its shock absorption, thus enhancing the entertainment value.
[0443] By configuring the vibration device 223 to operate when the pressure value obtained from the sensor 224 exceeds a threshold, the vibration device 223 operates when the protrusions 211B and 212B are in close contact with the seated person, thus reliably transmitting vibration to the user.
[0444] [Ninth Implementation Method]
[0445] Next, the ninth embodiment will be described in detail with reference to the accompanying drawings. Furthermore, this embodiment modifies a portion of the structure of the vehicle system 201 of the eighth embodiment; therefore, structures or processes identical to those in the eighth embodiment are labeled with the same symbols, and their descriptions are omitted.
[0446] The vehicle system 501 of the ninth embodiment includes an air chamber 522 whose location or size differs from that of the eighth embodiment. The size of the bag 222A in the air chamber 522 is larger than that of the air chamber 222 in the eighth embodiment, but the rest of the structure is the same as that of the air chamber 222 in the eighth embodiment.
[0447] An air chamber 522 (bag 222A) is provided in each of the two base portions 211A and 212A. The structure around the air chamber 522 in each base portion 211A and 212A is roughly the same, therefore, the following description refers to... Figure 28 The structure of the base portion 211A of the seat cushion 211 will be used as an example for explanation. The structure of the base portion 212A of the seat back 212 will be omitted from the explanation.
[0448] like Figure 28 As shown in (a) and (b), the air chamber 522 is an electric device that moves a portion of the seating surface F2 of the base portion 211A. The base portion 211A also has a vibration device 223 and a sensor 224.
[0449] Vibration device 223 can change the intensity of vibration. Furthermore, as a vibration device capable of changing the intensity of vibration, there are, for example, vibration devices that can change the vibration intensity by changing the vibration frequency and amplitude.
[0450] Vibration device 223 is located between sensor 224 and air chamber 522. Sensor 224 is located between skin SK and pad PD.
[0451] The control unit CT2 in the ninth embodiment executes... Figure 29 The processing.
[0452] Figure 29 In the processing, replace Figure 26 In the processing step S212, a new step S231 is set, and a new step S232 is set instead of step S217. Other processes are the same as... Figure 26 The processing is the same.
[0453] After step S211, the control unit CT2 causes the vibration device 223 to operate at a first intensity (S231). That is, when the stiffness of the suspension system is below a second predetermined value (S207: Yes), the control unit CT2 causes the vibration device 223, which operates after the air chamber 222 stops, to operate at the first intensity.
[0454] After step S216, the control unit CT2 causes the vibration device 223 to operate at a second intensity greater than the first intensity (S232). That is, when the stiffness of the suspension system is greater than a second predetermined value (S207: No), the control unit CT2 causes the vibration device 223, which operates after the air chamber 222 stops, to operate at a second intensity greater than the first intensity.
[0455] According to the ninth embodiment, the intensity of the vibration of the vibration device 223 is changed based on the stiffness of the suspension system, so that the occupant can understand that the stiffness of the suspension system has changed based on the intensity of the vibration. In particular, when the stiffness of the suspension system is greater than a second predetermined value, the intensity of the vibration is set to a second intensity that is greater than the first intensity, so that the occupant can intuitively understand that the stiffness of the suspension system has changed based on the intensity of the vibration.
[0456] Furthermore, the stiffer the suspension system, the more the air chambers 522 located in the base section 211A and base section 212A expand. As a result, the base section 211A and base section 212A become stiffer, and the impact from the road surface is more easily transmitted to the occupant. Therefore, the occupant can understand the state of the suspension system.
[0457] Furthermore, instead of the air chamber 522, a hardness-variable member capable of changing hardness can be provided in the base portion 211A and base portion 212A. For example, a member in which magnetic fluid is sealed in a bag 222A, such as the air chamber 522, can be used as the hardness-variable member. In this case, the control unit CT2 can also change the hardness of the hardness-variable member by applying magnetic force to the magnetic fluid using an electromagnet.
[0458] In addition, in the aforementioned case, the control unit CT2 executes... Figure 30 The processing. Figure 30 In addition to having Figure 29 In addition to steps S201-S203, S207, S208, S213, S231, and S232, the process also includes new steps S251-S253.
[0459] After step S203, control unit CT2 changes the hardness of the variable hardness member to make the hardness of the pad PD (hereinafter also referred to as "pad hardness") a first hardness (S251). After step S208, control unit CT2 changes the hardness of the variable hardness member to make the pad hardness a second hardness greater than the first hardness (S252), and proceeds to step S231. After step S213, control unit CT2 changes the hardness of the variable hardness member to make the pad hardness a third hardness greater than the second hardness (S253), and proceeds to step S232.
[0460] That is, when the stiffness of the suspension system is below a first predetermined value (S202: Yes), the control unit CT2 sets the bushing stiffness to a first stiffness. When the stiffness of the suspension system is above the first predetermined value but below a second predetermined value (S207: Yes), the control unit CT2 sets the bushing stiffness to a second stiffness. When the stiffness of the suspension system is above the second predetermined value (S207: No), the control unit CT2 sets the bushing stiffness to a third stiffness.
[0461] In the described configuration, the stiffer the suspension system, the stiffer the base portion 211A and base portion 212A, the easier it is for the impact from the road surface to be transmitted to the occupant, thus allowing the occupant to understand the state of the suspension system.
[0462] like Figure 31 As shown in (a) and (b), the control unit CT2 can also compare the extension and retraction of the springs SP1 of the left and right suspension devices SP, and expand the air chamber 222 to move the inner surfaces F3 of the retracted protrusions 211B and 212B to the left and right inwards. For example, if the control unit CT2 determines that the left spring SP1 is retracted than the right spring SP1, it expands the left air chamber 222, thereby moving the inner surfaces F3 of the left protrusions 211B and 212B to the left and right inwards. Furthermore, in this case, for example, an image of a cat resting on the left spring SP1 and an image of the cat pressing the left protrusions 211B and 212B to the left and right inwards can be displayed on the screen M21.
[0463] like Figure 32 As shown, the impact-absorbing component can also be an adjustment device 280 for adjusting the hardness of the tire T. The adjustment device 280 has a hardness-variable frame 281 capable of changing the hardness, and an energizing part (not shown) that supplies power to the hardness-variable frame 281.
[0464] The variable stiffness frame 281 is embedded in a rubber tire T. The variable stiffness frame 281 can change its stiffness by applying an electric current.
[0465] The control unit CT2 can also adjust the hardness of the tire T by controlling the adjustment device 280 to change the impact absorption.
[0466] In addition, as an adjustment device, it may be a device that adjusts the hardness of the tire by adjusting the tire pressure (for example, see Japanese Patent Application Publication No. 2006-182235).
[0467] The operating unit is not limited to a switch for changing the drive mode; for example, it can be a keyboard or touch screen that allows input of values corresponding to impact absorption, such as hardness.
[0468] The sensor can also be a capacitive touch sensor, for example.
[0469] Electrical equipment may also be the equipment shown below.
[0470] • A movable device that deforms the shape of a seat by driving a plate member (e.g., a device that operates the left and right protrusions that protrude from the seat cushion or seat back, or a device that operates a portion of the seat back or seat cushion).
[0471] Vibration devices can be any type of device, including those with a motor and wiring harness that emit vibration, eccentric motors, or linear motors. Vibration devices can be installed in seat cushions, headrests, etc. They can also be installed on the left or right extensions of seat cushions or seat backs.
[0472] The display unit can be installed in any location, such as the instrument panel, center console, steering mechanism, gauges, seat backs, door sides, or trim. Alternatively, it can be a projection device for projected images. It can also be a portable terminal such as a smartphone or tablet held by the occupant.
[0473] The character can be an animal other than a cat, a living being such as a plant, or a personified version of an object or creature. The character can be pre-defined, for example, it can be an image of a occupant transformed.
[0474] The vehicle is not limited to automobiles, but can also be other vehicles, such as two-wheeled vehicles, trams, etc.
[0475] The following methods can be listed as examples of manufacturing methods for vehicle systems.
[0476] A method for manufacturing a vehicle system, the vehicle system comprising: a vehicle body frame for supporting a seat; an impact-absorbing component disposed between a road surface and the vehicle body frame for absorbing impacts from the road surface and capable of varying the degree of impact absorption; an electric device for moving a portion of the occupant-side surface of the seat; and a control unit that operates the electric device based on the degree of impact absorption. The method for manufacturing the vehicle system includes: a step of installing the electric device on the seat; a step of installing the seat, the impact-absorbing component, and the control unit on the vehicle body frame; and a step of connecting the electric device to the control unit.
[0477] [Tenth Implementation Method]
[0478] The tenth embodiment will now be described with reference to the accompanying drawings.
[0479] like Figure 33As shown, the vehicle system 301 includes a seat 310, a robot 330, and a control unit CT3. The seat 310 and the robot 330 are interior components arranged in a position facing the passenger compartment. In this embodiment, the seat 310 is configured as a driver's seat.
[0480] The seat 310 includes a seat body 310A, an electric height mechanism HT, an electric tilt mechanism RC and an electric sliding mechanism SD as examples of electric devices, and a height switch 364, a tilt switch 361 and a sliding switch 362 as examples of operating units.
[0481] The seat body 310A is a component that provides a seating surface for the user. The seat body 310A includes a seat cushion 311, a seat back 312, and a headrest 313. The seat cushion 311, seat back 312, and headrest 313 each have a metal frame forming the skeleton, a padding covering the frame, and a cover covering the padding. The padding may contain urethane foam, etc. The cover may contain synthetic leather or fabric, etc. The upper surface of the seat cushion 311 is the seating surface. The front surfaces of the seat back 312 and headrest 313 are also seating surfaces.
[0482] The electric height mechanism HT is the mechanism that moves the seat body 310A up and down. The electric height mechanism HT includes a motor that operates by being powered by electricity.
[0483] The electric tilt mechanism RC is the mechanism that tilts the seat back 312. The electric tilt mechanism RC includes a motor that operates by being energized.
[0484] The electric sliding mechanism SD is a device that moves the seat 310 in the fore-and-aft direction. Here, the seat 310 is supported on the slide rail SR, which allows it to move in the fore-and-aft direction. The electric sliding mechanism SD includes a motor that operates by being energized.
[0485] The height switch 364 is an operating unit for operating the electric height mechanism HT. The height switch 364 can slide, for example, in the vertical direction. When the height switch 364 slides upward, it outputs a raising command to the control unit CT3 to move the seat body 310A upward. When the height switch 364 slides downward, it outputs a lowering command to the control unit CT3 to move the seat body 310A downward.
[0486] The tilt switch 361 is an operating unit for operating the electric tilt mechanism RC. The tilt switch 361 can tilt in the forward and backward direction, for example. When tilted forward, the tilt switch 361 outputs a forward tilt command to the control unit CT3 to tilt the seat back 312 forward. When tilted backward, the tilt switch 361 outputs a backward tilt command to the control unit CT3.
[0487] The slide switch 362 is an operating unit for operating the electric sliding mechanism SD. The slide switch 362 can slide in, for example, the forward and backward direction. When the slide switch 362 slides forward, it outputs a forward command to the control unit CT3 to move the seat 310 forward. When the slide switch 362 slides backward, it outputs a backward command to the control unit CT3 to move the seat 310 backward.
[0488] The robot 330 is positioned in a location visually identifiable to the user seated on the seat 310. In this embodiment, the robot 330 is positioned on the dashboard D. More specifically, as... Figure 34 As shown, robot 330 is positioned in the center of the dashboard D in the left-right direction.
[0489] like Figure 35 As shown, the robot 330 has a robot body 331, two arms 332, and a screen 333, which serves as an example of a display unit.
[0490] The robot body 331 has a main shell 331A, two arm drive devices 331B, and a vibration device 331C.
[0491] The main body shell 331A comprises resin or metal, etc. The main body shell 331A is formed in a generally hemispherical shape (see reference). Figure 36 (d)).
[0492] The arm drive device 331B is a device that causes the arm 332 to rotate up and down by means of electricity.
[0493] Vibration device 331C is a device that vibrates by means of electricity.
[0494] Each arm 332 is rotatably supported on the main housing 331A. Each arm 332 extends upward from the left and right sides of the main housing 331A. Figure 36 As shown in (a), each arm 332 can rotate between a first arm position facing upwards and a second arm position facing outwards in the left-right direction via an arm drive device 331B.
[0495] Screen 333 can display images representing the eyes or mouth of robot 330, etc.
[0496] Robot 330 is supported by robot support device RM.
[0497] The robot support device RM has a rotation mechanism RM1 that supports the robot body 331 in a rotatable manner, a lifting mechanism RM2 that moves the rotation mechanism RM1 in the vertical direction, and a forward and backward movement mechanism RM3 that moves the lifting mechanism RM2 in the forward and backward direction.
[0498] like Figure 36As shown in (c), the rotating mechanism RM1 has the function of tilting the robot 330 in the left and right directions. Additionally, as... Figure 36 As shown in (d), the rotating mechanism RM1 has the function of tilting the robot 330 in the forward and backward direction. Additionally, the rotating mechanism RM1 has the function of rotating the robot 330 about a vertical axis (see reference). Figure 44 (a)).
[0499] like Figure 36 As shown in (b), the lifting mechanism RM2 has the function of moving the robot 330 in the vertical direction by moving the rotating mechanism RM1 in the vertical direction.
[0500] like Figure 36 As shown in (d), the forward and backward moving mechanism RM3 has the function of moving the robot 330 and the rotating mechanism RM1 in the forward and backward direction by moving the lifting mechanism RM2 in the forward and backward direction.
[0501] The control unit CT3 includes a CPU (not shown), ROM, RAM, and rewritable non-volatile memory, and executes pre-stored programs. The control unit CT3 is connected to the various electrical devices and operating units of the seat 310, as well as the robot 330. Furthermore, the control unit CT3 can be installed in the seat 310 or in a component other than the seat 310.
[0502] The control unit CT3 has the function of performing linkage processing to link the actions of the robot 330 with the actions of the electric equipment. The control unit CT3 performs linkage processing based on information obtained from the operation unit.
[0503] Specifically, such as Figure 37 As shown, when the user operates the tilt switch 361, the control unit CT3 activates the electric tilt mechanism RC to tilt the seat back 312 in the fore-and-aft direction, and activates the rotation mechanism RM1 to tilt the robot 330 in the fore-and-aft direction. Additionally, as... Figure 38 As shown, when the user operates the slide switch 362, the control unit CT3 activates the electric sliding mechanism SD to move the seat 310 in the front-back direction, and activates the front-back moving mechanism RM3 to move the robot 330 in the front-back direction.
[0504] Furthermore, such as Figure 39 As shown, when the user operates the height switch 364, the control unit CT3 activates the electric height mechanism HT to move the seat body 310A in the vertical direction, and activates the lifting mechanism RM2 to move the robot 330 in the vertical direction.
[0505] In detail, the control unit CT3 is based on operating commands and Figure 40The robot 330 is moved by the mapping diagram shown. Here, the operation command is a command for operating the seat 310, which refers to a tilt-forward command, tilt-back command, forward command, backward command, rise command, or fall command output from any of the plurality of switches (361, 362, 364). Furthermore, the operation of each electric device of the seat 310 in response to the operation command is known, so its description is omitted.
[0506] When the operating command is a forward tilt command, the control unit CT3 tilts the robot 330 forward.
[0507] Here, the so-called forward tilt of robot 330 refers to the robot 330 gradually tilting downwards as its viewpoint 333 gradually turns downwards. That is, the so-called forward tilt of robot 330 means that from the perspective of the user sitting in seat 310, robot 330 tilts towards the rear of the vehicle (user side).
[0508] When the control unit CT3 issues a tilt-back command, it causes the robot 330 to tilt backward. Here, the tilting of the robot 330 means that the robot 330 gradually tilts upward as its viewpoint 333 gradually turns upward. That is, the tilting of the robot 330 means that, from the perspective of the user seated in the seat 310, the robot 330 tilts towards the front of the vehicle (away from the user).
[0509] When the operating command is a forward command, the control unit CT3 causes the robot 330 to move forward. Here, the forward movement of the robot 330 means that, from the perspective of the user seated in the seat 310, the robot 330 moves towards the rear of the vehicle (user side).
[0510] When the operating command is a reverse command, the control unit CT3 causes the robot 330 to move backward. Here, the reversal of the robot 330 means that, from the perspective of the user seated in seat 310, the robot 330 moves forward of the vehicle (away from the user).
[0511] When the operating command is an upward command, the control unit CT3 causes the robot 330 to rise. When the operating command is a downward command, the control unit CT3 causes the robot 330 to descend.
[0512] Control unit CT3 repeatedly executes Figure 41 The processing.
[0513] exist Figure 41 In the process, the control unit CT3 first determines whether an operation command exists (S301). If it is determined in step S301 that no operation command exists (No), the control unit CT3 ends the process.
[0514] If an operation command is determined to exist in step S301 (Yes), the control unit CT3 causes the electric device of the seat 310 corresponding to the operation command to operate in accordance with the operation command (S302). After step S302, the control unit CT3 causes the vibration device 331C of the robot 330 to operate (S303).
[0515] After step S303, the control unit CT3, based on the operation command and... Figure 40 The robot 330 moves according to the mapping (S304). After step S304, the control unit CT3 ends the process.
[0516] Next, a specific example of the operation of the control unit CT3 will be explained.
[0517] like Figure 37 As shown, when the user tilts the tilt switch 361 backward, a tilt command is output from the tilt switch 361 to the control unit CT3. After receiving the tilt command, the control unit CT3 activates the electric tilt mechanism RC to tilt the seat back 312 backward.
[0518] In addition, the control unit CT3 causes the vibration device 331C (see reference) Figure 35 The operation of the mechanism causes the robot 330 to vibrate and the rotating mechanism RM1 to tilt the robot 330 backward. As a result, the user who observes the movement of the robot 330 can feel that the robot 330 is mimicking the movement of the seat 310, thus creating a sense of closeness to the robot 330.
[0519] Based on this embodiment, the following effects can be obtained.
[0520] Because the robot 330 and the seat 310 are linked by electric devices, the entertainment value is improved compared to a structure where only the robot moves.
[0521] By setting the control unit CT3 to perform linkage processing based on information obtained from the operation unit, the user feels that the robot 330 is imitating the movements of the seat 310 and thus feels close to the robot 330, thereby improving the entertainment value.
[0522] Furthermore, in the tenth embodiment, in the linkage process, the robot 330 is moved after the seat 310 is moved; however, conversely, in the linkage process, the seat 310 may be moved after the robot 330 is moved. In this case, simply... Figure 41 The processing in step S302 can be moved to step S304. Alternatively, in the linkage processing, the actions of the robot 330 and the seat 310 can be started simultaneously.
[0523] In a linkage process where the robot 330 moves before the seat 310, the control unit CT3 activates the electric devices based on the robot 330's movements. In this structure where the seat 310's electric devices operate based on the robot 330's movements, the user can also experience the robot 330's actions, thus enhancing entertainment. Furthermore, in this structure where the seat 310's electric devices operate based on the robot 330's movements, for example, the control unit CT3 can also move the robot 330 under conditions different from the operating instructions, and then move the seat 310 based on the robot 330's movements.
[0524] [Eleventh Implementation Method]
[0525] Next, the eleventh embodiment will be described in detail with reference to the accompanying drawings. Furthermore, since this embodiment modifies part of the structure of the vehicle system 301 of the tenth embodiment and part of the operation of the control unit CT3, the same reference numerals are used for structures and processes identical to those of the tenth embodiment, and their descriptions are omitted.
[0526] like Figure 42 As shown, the vehicle system 601 of the eleventh embodiment includes a seat 610 with a slightly different structure from that of the tenth embodiment. The seat 610 also includes a seat body 610A with a structure substantially the same as that of the seat body 310A of the tenth embodiment, and a vibration device 370, an air chamber 380, a first sensor 341, a second sensor 342, and a mode switching switch 363, which are not present in the tenth embodiment. In this embodiment, the vibration device 370 corresponds to an electric device, and the air chamber 380 corresponds to a second electric device different from the electric device.
[0527] The seat cushion 311 has: a base portion 311A disposed at the left and right center; and extension portions 311B disposed on the outer sides of both sides of the base portion 311A. The base portion 311A has a seating surface F4 that contacts and supports the user's buttocks and thighs from below. The extension portions 311B extend from the seating surface F4 of the base portion 311A toward the user side to support the sides of the user's thighs and buttocks.
[0528] Furthermore, the seat back 312 also includes: a base portion 312A, disposed at the center on the left and right sides; and an extension portion 312B, disposed on the outer sides of both sides of the base portion 312A. The base portion 312A has a seating surface F4 that contacts the user's back and supports the back from behind. The extension portion 312B extends from the seating surface F4 of the base portion 312A toward the user side to support the sides of the user's upper body.
[0529] The vibration device 370 is a device that vibrates the seating surface F4 of the seat 610. In this embodiment, the vibration device 370 is provided in the base portion 312A of the seat back 312. For example, one vibration device 370 is provided on each of the left and right sides of the base portion 312A. The vibration device 370 is positioned corresponding to the back of the user sitting in the seat 610.
[0530] The air chamber 380 is an electric device that moves the seating surface F4 of the seat 610. In this embodiment, the air chamber 380 is provided in the base portion 312A of the seat back 312.
[0531] The air chamber 380 includes an inflatable / contractable bag 381, and a pump and tubing (not shown). The pump, which is powered by electricity, is capable of supplying or drawing air into or out of the bag 381. The tubing connects the bag 381 to the pump.
[0532] The bag 381 is embedded in the padding. Additionally, the pump is, for example, fixed to the frame of the seat 610. The bag 381 is positioned corresponding to the waist of the user seated in the seat 610. The bag 381 is located below the vibration device 370.
[0533] The seat cushion 311 has a first sensor 341. The headrest 313 has a second sensor 342.
[0534] The first sensor 341 and the second sensor 342 are sensors that detect when a user touches the seat 610. Specifically, the first sensor 341 and the second sensor 342 are pressure sensors that detect pressure from the user. The first sensor 341 and the second sensor 342 are positioned away from the seat surface F4.
[0535] In detail, one first sensor 341 is provided on each of the left and right protrusions 311B of the seat cushion 311.
[0536] The second sensor 342 is positioned differently from the first sensor 341. Specifically, one second sensor 342 is provided on each of the left and right sides of the headrest 313. The first sensor 341 and the second sensor 342 are located between the outer skin and the padding, respectively.
[0537] The mode switch 363 is used to switch the control unit CT3 between a first mode and a second mode. Here, the first mode is the mode that performs linkage processing. The second mode is the mode that does not perform linkage processing. The mode switch 363 is, for example, a push-button switch. Each time the user presses the switch, the mode switch 363 alternately switches between an on and off state. In this embodiment, when the mode switch 363 is in the off state, the mode is the second mode; when the mode switch 363 is in the on state, the mode is the first mode.
[0538] According to the eleventh embodiment, the control unit CT3 has the function of performing linkage processing based on information obtained from the first sensor 341 or the second sensor 342. Specifically, as Figure 43 As shown, when the control unit CT3 obtains information from the first sensor 341, it causes the robot 330 to run in a first row based on the information from the first sensor 341, and also causes the vibration device 370 of the seat 610 to operate. In this embodiment, the first row is defined as the action of opening / closing each arm 332 of the robot 330, that is, the action of each arm 332 moving up and down. The control unit CT3 causes each arm 332 to open / close by activating the drive device 331B of each arm.
[0539] like Figure 44 As shown, when the control unit CT3 obtains information from the second sensor 342, it causes the robot 330 to operate in a second action different from the first action, and also activates the air chamber 380 of the seat 610. In this embodiment, the second action is defined as the robot 330 rotating about a vertical axis. The control unit CT3 causes the robot 330 to rotate by activating the rotation mechanism RM1.
[0540] The control unit CT3 of the eleventh embodiment executes repeatedly. Figure 45 The processing.
[0541] exist Figure 45 In the process, the control unit CT3 first determines whether the mode switching switch 363 is turned on (S321). If it is determined in step S321 that the mode switching switch 363 is not turned on (No), the control unit CT3 sets the mode to the second mode (S327) and ends the process.
[0542] If, in step S321, it is determined that the mode switching switch 363 is on (Yes), the control unit CT3 sets the mode to the first mode (S322). After step S322, the control unit CT3 determines whether there is an input to the second sensor 342 (S323). Furthermore, the determination of whether there is an input to the second sensor 342 can be performed, for example, by determining whether the pressure obtained from the second sensor 342 is above a second threshold.
[0543] If, in step S323, it is determined that there is input from the second sensor 342 (Yes), the control unit CT3 activates the vibration device 331C of the robot 330 (S324). After step S324, the control unit CT3 rotates the robot 330 (S325).
[0544] After step S325, the control unit CT3 repeatedly expands and contracts the bag 381 of the air chamber 380 of the seat 310 at a predetermined cycle and within a predetermined time period (S326). After step S326, the control unit CT3 ends this process.
[0545] If it is determined in step S323 that the second sensor 342 has no input (No), the control unit CT3 determines whether the first sensor 341 has input (S328). Furthermore, determining whether the first sensor 341 has input can be done, for example, by determining whether the pressure obtained from the first sensor 341 is above a first threshold.
[0546] If, in step S328, it is determined that there is input to the first sensor 341 (yes), the control unit CT3 activates the vibration device 331C of the robot 330 (S329). After step S329, the control unit CT3 opens / closes the arm 332 of the robot 330 (S330).
[0547] After step S330, the control unit CT3 causes the vibration device 370 of the seat 310 to operate for a predetermined time (S331). Furthermore, as a method of operating the vibration device 370 in step S331, it is sufficient to operate at least one of the left and right vibration devices 370. For example, the left and right vibration devices 370 can vibrate simultaneously or the left and right vibration devices 370 can vibrate alternately.
[0548] After step S331, the control unit CT3 ends the process. Additionally, if in step S327 it is determined that the first sensor 341 has no input (No), the control unit CT3 ends the process.
[0549] Next, a specific example of the operation of the control unit CT3 will be explained.
[0550] like Figure 43As shown in (b), when a pressure exceeding a first threshold is input to the first sensor 341 due to the user pressing the inner surface of the protrusion 311B of the seat cushion 311, as... Figure 43 As shown in (a), the control unit CT3 opens / closes the arm 332 of the robot 330 and activates the vibration device 370 of the seat 310 to vibrate the seat back 312.
[0551] like Figure 44 As shown in (b), when a pressure exceeding a second threshold is input to the second sensor 342 due to the user pressing the side of the headrest 313, as... Figure 44 As shown in (a), the control unit CT3 causes the robot 330 to rotate about the vertical axis and causes the bag 381 of the air chamber 380 of the seat 310 to expand / contract.
[0552] According to the eleventh embodiment, the following effects can be obtained.
[0553] When a user touches the seat 310, the seat 310 and the robot 330 will move, so that the user can feel that he is communicating with the robot 330 through the seat 310, thus enhancing the entertainment.
[0554] The robot 330 and the seat 310 move in a manner corresponding to the position of the seat 310 touched by the user, thus enhancing the entertainment experience.
[0555] [Twelfth Implementation Method]
[0556] Next, the twelfth embodiment will be described in detail with reference to the accompanying drawings. Furthermore, since this embodiment modifies part of the structure of the vehicle system 301 of the tenth embodiment and part of the operation of the control unit CT3, the same reference numerals are used for structures and processes identical to those of the tenth embodiment, and their descriptions are omitted.
[0557] like Figure 46 As shown in (a), the vehicle system 701 of the twelfth embodiment includes a plurality of seats 310 identical to those in the tenth embodiment, as well as a sound acquisition unit 730. Furthermore, in this embodiment, the plurality of seats 310 are provided as a driver's seat and a passenger seat, but the number of seats 310 may be three or more.
[0558] The sound acquisition unit 730 has the function of acquiring sound. The sound acquisition unit 730 is, for example, a microphone. The sound acquisition unit 730 is built into the robot 330. Alternatively, the sound acquisition unit 730 may be installed in a component other than the robot 330, such as the seat 310 or the dashboard.
[0559] The control unit CT3 of the twelfth embodiment has the function of performing linkage processing based on operation commands from the user's voice acquired by the voice acquisition unit 730. The control unit CT3 also has the function of selecting a seat 310 from a plurality of seats 310 as the object to be performed linkage processing based on the operation commands.
[0560] The control unit CT3 has the following functions: when performing linkage processing on the specified seat 310, such as Figure 46 As shown in (b), the robot 330 is moved so that its screen 333 faces the designated seat 310, and then the linkage process is executed. Figure 46 As shown in (c), the control unit CT3 has the function of displaying an image of the seat 310 on the screen 333 of the robot 330. For example... Figure 46 As shown in (d), the control unit CT3 has the function of moving the seat image during linkage processing.
[0561] The control unit CT3 of the twelfth embodiment executes repeatedly. Figure 47 The processing.
[0562] exist Figure 47 In the processing, the control unit CT3 first determines whether there is a sound-based operation command based on the information obtained from the sound acquisition unit 730 (S351). Here, the operation command includes information such as seat position, part of the seat 310 that is the object of the action, direction of action, and amount of action.
[0563] Seat position indicates whether it is the driver's seat or the front passenger seat. The location of seat 310 indicates, for example, the seat back 312 when the user reclines seat 310. Direction of movement indicates, for example, forward or backward movement when the user reclines seat 310. Amount of movement indicates, for example, the angle of seat back 312 when the user reclines seat 310.
[0564] In step S351, if the control unit CT3 has acquired all the aforementioned information, it determines that an operation command exists. If, in step S351, it is determined that no operation command exists, i.e., if all information is incomplete (No), the control unit CT3 terminates this process.
[0565] If, in step S351, it is determined that an operation command exists, i.e., all information is complete (Yes), the control unit CT3 activates the rotation mechanism RM1 to rotate the robot 330 so that the robot 330's screen 333 faces the seat 310 corresponding to the seating position (S352). After step S352, the control unit CT3 displays the seat image and the image corresponding to the operation command on screen 333 (S353).
[0566] After step S353, the control unit CT3 activates the arm drive 331B corresponding to the seat position among the two arm drive devices 331B, causing the arm 332 on the seat position side of the robot 330 to open, that is, to rotate the arm 332, so that the tip of the arm 332 changes from an upward-facing state to a left-right outward state (S354). After step S354, the control unit CT3 moves the seat image with an action corresponding to the operation command. For example, when the user tilts the seat 310, the control unit CT3 rotates the seat back portion of the seat image.
[0567] After step S355, the control unit CT3 activates the electric mechanism of the seat 310 corresponding to the seat position based on the seat position, action object, action direction, and action amount included in the operation command (S356). For example, when the user tilts the front passenger seat, the control unit CT3 activates the electric tilting mechanism RC of the front passenger seat to rotate the seat back 312 until it reaches the posture corresponding to the operation command. After step S356, the control unit CT3 ends this process.
[0568] Next, a specific example of the operation of the control unit CT3 will be explained.
[0569] like Figure 46 As shown in (b), when the user in the front passenger seat gives the robot 330 a voice-based command such as "Recline the front passenger seat back 20°," the robot 330 rotates, and its screen 333 faces the front passenger seat. Subsequently, as... Figure 46 As shown in (c), the control unit CT3 displays an image of the seat and an image of an arrow indicating that the seat back should be tilted back on screen 333.
[0570] Subsequently, as Figure 46 As shown in (b), the control unit CT3 opens the arm 332 on the passenger side of the robot 330 and displays a dynamic image of the seat back rotating 20° backward on the screen 333. Subsequently, the control unit CT3 causes the seat back 312 of the actual seat 310 (passenger seat) to rotate 20° backward from its current position.
[0571] Furthermore, the operating command can be either a command to move the seat 310 in the front-to-back direction or a command to move the seat body 310A in the up-down direction.
[0572] According to the twelfth embodiment, the following effects can be achieved.
[0573] Because the seat image moves during the linkage process, the user can easily understand the movement of the seat 310 through the seat image.
[0574] When the linkage process is performed on the designated seat 310, the screen 333 is oriented towards the designated seat 310, so the user sitting in the designated seat 310 can easily observe the seat image and feel that they are communicating with the robot 330.
[0575] [Thirteenth Implementation Method]
[0576] Next, the thirteenth embodiment will be described in detail with reference to the accompanying drawings. Furthermore, since this embodiment modifies part of the structure of the vehicle system 601 and part of the operation of the control unit CT3 as described in the eleventh embodiment, the same reference numerals are used for structures and processes identical to those in the eleventh embodiment, and their descriptions are omitted.
[0577] like Figure 48 As shown, the vehicle system 801 of the thirteenth embodiment includes a seat 810 with a slightly different structure from that of the eleventh embodiment, and an acceleration sensor 820. The seat 810 includes a seat body 810A with a structure substantially the same as that of the seat body 610A of the eleventh embodiment, a plurality of air chambers 380, 390, and a blower BL.
[0578] The air chamber 380 is an air chamber of approximately the same size as the bag 381 in the eleventh embodiment.
[0579] The air chamber 390 is an air chamber of a bag 391 that is smaller than the bag 381 of the eleventh embodiment.
[0580] The seat back 312 has one air chamber 380 and two air chambers 390.
[0581] The pocket 381 of the air chamber 380 of the seat back 312 is located in the same position as in the eleventh embodiment.
[0582] The air chamber 390 of the seat back 312 is provided on each of the left and right protrusions 312B of the seat back 312. The air chamber 390 of the seat back 312 causes a portion of the inner side F5 of the protrusion 312B located in the left and right direction to move.
[0583] The seat cushion 311 has one air chamber 380 and two air chambers 390.
[0584] The air chambers 380 of the seat cushion 311 are positioned corresponding to the buttocks of the user sitting in the seat 810. The air chambers 380 of the seat cushion 311 cause a portion of the seating surface F4 of the seat cushion 311 to move.
[0585] The air chamber 390 of the seat cushion 311 is provided on each of the left and right protrusions 311B of the seat cushion 311. The air chamber 390 of the seat cushion 311 causes a portion of the inner side F5 of the protrusion 311B located in the left-right direction to move.
[0586] Two air chambers 380 are located in the center of the seat 810 in the left-right direction. Four air chambers 390 are located further to the left or right than the air chambers 380. In the following description, air chamber 380 will also be referred to as "central air chamber 380", and air chamber 390 will also be referred to as "left air chamber 390 or right air chamber 390".
[0587] The blower BL is installed in the seat cushion 311. The air delivered from the blower BL passes through the passage formed in the padding of the seat cushion 311 and then passes through the surface toward the user.
[0588] Accelerometer 820 is a sensor that detects the vehicle's acceleration in the forward and backward directions as well as its acceleration in the left and right directions. The forward and backward acceleration and the left and right acceleration detected by accelerometer 820 are output to control unit CT3. Furthermore, accelerometer 820 can be installed in the vehicle, or in robot 330 or seat 810.
[0589] The control unit CT3 has the following functions: based on the left-right acceleration obtained from the accelerometer 820, it tilts the robot 330 in the left-right direction and activates either of the left or right air chambers 390. For example... Figure 49 As shown, the control unit CT3 has the following functions: based on the acceleration in the front-back direction obtained from the acceleration sensor 820, it causes the robot 330 to tilt in the front-back direction and activates the central air chamber 390.
[0590] Control unit CT3 repeatedly executes Figure 50 The processing.
[0591] exist Figure 50 In the process shown, the control unit CT3 first determines whether the acceleration in the left direction is above the threshold based on the information obtained from the acceleration sensor 820 (S361).
[0592] If, in step S361, it is determined that the acceleration in the left direction is above a threshold (Yes), the control unit CT3 tilts the robot 330 to the left (S362). After step S362, the control unit CT3 inflates the air chamber 390 on the right side (S363).
[0593] Furthermore, in step S363, it is sufficient to inflate at least one of the two air chambers 390 located on the right side of the seat 810. After step S363, the control unit CT3 terminates this process.
[0594] If, in step S361, it is determined that the acceleration in the left direction is not above the threshold (No), the control unit CT3 determines, based on information obtained from the acceleration sensor 820, whether the acceleration in the right direction is above the threshold (S364). If, in step S364, it is determined that the acceleration in the right direction is above the threshold (Yes), the control unit CT3 tilts the robot 330 to the right (S365). After step S365, the control unit CT3 inflates the air chamber 390 on the left side (S366).
[0595] Furthermore, in step S366, it is sufficient to inflate at least one of the two air chambers 390 located on the left side of the seat 810. After step S366, the control unit CT3 terminates this process.
[0596] If, in step S364, it is determined that the acceleration in the right direction is not above the threshold (No), the control unit CT3 determines whether the acceleration in the forward direction is above the threshold based on the information obtained from the acceleration sensor 820 (S367). If, in step S367, it is determined that the acceleration in the forward direction is above the threshold (Yes), the control unit CT3 tilts the robot 330 backward (S368).
[0597] After step S368, the control unit CT3 contracts the central air chamber 380 (S369). Furthermore, in step S369, it is sufficient to contract at least one of the two air chambers 380 located in the left-right center of the seat 810.
[0598] After step S369, the control unit CT3 operates the blower BL for a predetermined period of time (S370), ending the process. Furthermore, the threshold values in steps S361, S364, and S367 can be different values or the same value. Additionally, at the end of this process, the control unit CT3 restores the robot 330's posture to its original position and restores the air chamber 390 or air chamber 380 to its reference size.
[0599] Next, a specific example of the operation of the control unit CT3 will be explained.
[0600] If the leftward acceleration detected by the acceleration sensor 820 due to the vehicle turning left exceeds a threshold, such as Figure 48 As shown in (a), from the user's perspective, the control unit CT3 tilts the robot 330 to the left. Subsequently, as... Figure 48 As shown in (b), the control unit CT3, for example, expands the two air chambers 390 on the right side, causing the inner surface F5 on the right side to move inward in the left-right direction.
[0601] As a result, the user experiences pressure from the extensions 311B and 312B on the right side of the seat 810, causing the user's body to tilt to the left. Therefore, the robot 330's movements are synchronized with the user's body movements, allowing the user to feel as if they are turning left together with the robot 330, thus enhancing the entertainment experience.
[0602] Furthermore, if the forward acceleration detected by the acceleration sensor 820 due to vehicle acceleration exceeds a threshold, such as Figure 49 As shown in (a), the control unit CT3 tilts the robot 330 backward (forward from the user's perspective). Thereafter, as... Figure 49 As shown in (b), the control unit CT3, for example, causes the two central air chambers 380 to contract, thereby moving the seating surfaces F4 of the seat cushion 311 and seat back 312 away from the user. Furthermore, the control unit CT3 activates the blower BL, causing air from the blower BL to flow towards the user.
[0603] As a result, the user's body sinks into the seat 810, and the user feels the wind. Thus, the user can feel the vehicle's acceleration from the robot 330's movements, and because of the vehicle's acceleration, the user's body sinks into the seat 810, and the user can feel the wind generated by the vehicle's acceleration, thus enhancing the entertainment experience.
[0604] According to the thirteenth embodiment, the following effects can be obtained.
[0605] Because users can feel the acceleration in the front and rear directions of the vehicle through the tilting of the robot 330 and the operation of the air chamber 380, users can feel a sense of oneness with the vehicle.
[0606] Because users can feel the vehicle's left and right acceleration through the tilting of the robot 330 and the operation of the air chamber 390, they can feel a sense of unity with the vehicle.
[0607] When the vehicle turns left, the right-side air chamber 390 expands, thus the right-side extensions 311B and 312B can be used to support the user when they move to the right due to centrifugal force. Similarly, when the vehicle turns right, the left-side extensions 311B and 312B can also be used to support the user.
[0608] Furthermore, when one of the air chambers on the left or right side is expanded, the air chamber on the other side can also be contracted.
[0609] Alternatively, the control unit can inflate the air chamber on one side (the side in the same direction as the robot's tilt) after tilting the robot to one side (left or right). That is, the tilting of the robot to the left and right and the operation of the air chambers on the left and right sides can be reversed compared to the thirteenth embodiment.
[0610] [Fourteenth Implementation]
[0611] Next, the fourteenth embodiment will be described in detail with reference to the accompanying drawings. Furthermore, since this embodiment modifies part of the structure of the vehicle system 301 of the tenth embodiment and part of the operation of the control unit CT3, the same reference numerals are used for structures and processes identical to those of the tenth embodiment, and their descriptions are omitted.
[0612] like Figure 51 As shown, the vehicle system 901 of the fourteenth embodiment also includes a camera CM2 as an example of a collision detection unit and a vibration device DV as an example of an electric device.
[0613] Camera CM2 is a camera that takes pictures of the front of the vehicle. The image information captured by camera CM2 is output to control unit CT3. Camera CM2 is installed, for example, on the roof of the vehicle.
[0614] The vibration device DV is a device that vibrates the seating surface of the seat 310. In this embodiment, the vibration device DV is provided on the seat back 312. For example, one vibration device DV is provided on the left side and one on the right side of the seating surface of the seat back 312.
[0615] The control unit CT3 has the function of predicting vehicle collisions based on information obtained from the camera CM2. The control unit CT3 has the following function: when a vehicle collision is predicted, it causes the robot 330 and the vibration device 70 to move in an action mode for notifying the user of the possibility of a vehicle collision.
[0616] Control unit CT3 repeatedly executes Figure 52 The processing.
[0617] exist Figure 52 In the process, the control unit CT3 determines whether there is a possibility of a vehicle collision based on the information obtained from the camera CM2 (S391). If it is determined in step S391 that there is no possibility of a collision (No), the control unit CT3 ends the process.
[0618] If a collision is deemed possible in step S391 (Yes), the control unit CT3 activates the vibration device 331C of the robot 330 (S392). The vibration mode of the vibration device 331C in step S392 may be, for example, a mode in which vibration is performed continuously for a relatively long first time period, or a mode in which vibration is performed multiple times for a relatively short second time period and the vibration is stopped for a relatively short third time period.
[0619] After step S392, the control unit CT3 activates the vibration device DV of the seat 310 (S393), ending the process. The vibration mode of the vibration device DV in step S393 may be the same as the vibration mode of the vibration device 331C of the robot 330, or it may be a different mode.
[0620] According to the fourteenth embodiment, the following effects can be obtained.
[0621] In the event of a potential vehicle collision, the robot 330 and seat 310 can vibrate to notify the user of the possibility of a collision, thereby improving safety.
[0622] It is also possible to make the intensity of the vibration when a collision is deemed possible greater than the intensity of the vibration when a collision is deemed not possible. For example, the control unit CT3 in the fourteenth embodiment can also perform this operation. Figure 41 In the case of such processing, the intensity of the vibration in step S303 can be set to a first intensity, and the intensity of the vibration in step S392 can be set to a second intensity greater than the first intensity. Furthermore, as a vibration device capable of changing the intensity of vibration, for example, a vibration device that changes the vibration frequency and amplitude to change the intensity of vibration can be used.
[0623] Furthermore, the actions of the robot and the electric devices of the seat in the event of a potential vehicle collision are not limited to the fourteenth embodiment. Ideally, the robot and the electric devices should move in an action pattern used to notify the user of the possibility of a vehicle collision.
[0624] Specifically, as actions of a robot, for example, can be Figure 43 The action of repeatedly opening / closing each arm 332 of robot 330 as shown in (a) can also be... Figure 44 (a) shows the action of rotating the robot 330 around the vertical axis. The action of the electric device of the seat could also be, for example, the action of repeatedly expanding / contracting the air chambers.
[0625] It can also be used as a substitute Figure 52 The collision probability determination in the process (S391) is used to set other determination processes. As other determination processes, the following processes can be listed as examples.
[0626] • The process of determining whether a vehicle has entered a highway will proceed to step S392 if it is determined that the vehicle has entered a highway.
[0627] • Determine whether the prescribed time has elapsed since boarding the vehicle. If the prescribed time has elapsed, proceed to step S392.
[0628] • The process of using the navigation system to determine whether the distance between the vehicle and the destination is below a specified value, and if it is determined that the distance is below the specified value, proceeds to step S392.
[0629] The trigger for the robot to begin moving can be set arbitrarily. For example, the control unit can cause the robot to move at a predetermined time, or it can move the robot based on the occupant's biological information or the vehicle's external information. In addition, the robot can also operate autonomously.
[0630] The actions of the robot and the electric devices of the seat are not limited to the described implementation, and may also include the following actions.
[0631] • When the robot waves, the armrests of the seat move. Specifically, the mechanism that causes the armrests to rotate is activated when the robot rotates one of its arms multiple times.
[0632] • The vibration device on the seat activates when the robot moves its arm multiple times.
[0633] • It tilts and leans in sync with the robot's desire to rest. Specifically, when the robot tilts backward, the electric tilting mechanism works by tilting the seat back backward.
[0634] • The air chamber activates when the robot moves its arm multiple times.
[0635] The sensor can also be a capacitive touch sensor.
[0636] Touch sensors can be located, for example, at the front end of the seat cushion, the protrusion of the seat cushion, the protrusion of the seat back, and the side of the headrest.
[0637] The seat is not limited to the structure of the described embodiment. For example, such as Figure 53 As shown, in addition to a seat cushion 260, a seat back 270, and a headrest 230, seat 200 may also have a leg rest 240 and an armrest 250. Furthermore, a console storage box CB may be installed next to seat 200.
[0638] exist Figure 53 In this configuration, the seat back 270 has: a first member 271 rotatably supported on the seat cushion 260; and a second member 272 rotatably supported on the upper part of the first member 271 and having a headrest 230 provided on the upper part.
[0639] In this case, the sensor 340 that outputs a signal for initiating the linkage process may be configured in at least one of the locations shown below.
[0640] • The left and right extensions 261 of the seat cushion 260
[0641] • The front surface of the seat cushion 260
[0642] • The left and right protrusions 271A of the first component 271
[0643] • The left and right protrusions 272A of the second component 272
[0644] • The seat backrest is positioned approximately 270 degrees on the side or back.
[0645] • The left and right sides, lower surface, or back of the headrest 230
[0646] • The front end, top surface, inner left and right sides, or outer left and right sides of the handrail 250
[0647] ·Legged side of the leg support 240
[0648] • The left and right inner sides or left and right outer sides of the console storage box CB
[0649] In addition, such as Figure 54 As shown, sensor 340 can also be installed on steering device ST as indicated by the dotted shaded lines in the figure.
[0650] like Figure 55 As shown, sensor 340 can also be installed in the center console storage box 441, instrument panel 442, door panel, or inner panel 443 of the vehicle, as indicated by the dotted shaded lines. Alternatively, sensor 340 can be installed inside a cylindrical blower 444. The cylindrical blower 444 has air outlets in its cylindrical body for supplying air into the vehicle interior.
[0651] In addition, such as Figure 56 As shown by the dotted shaded lines in the figure, sensor 340 can also be installed on components (seat cushions, seat backs, headrests) that constitute at least one of the seats 451 in the first row, 452 in the second row, or 453 in the third row. Additionally, sensor 340 can also be installed on the roof 454, the cover 455 for opening / closing the sunroof, the auxiliary handle 456, the upper part of the back of the seat back, the upper surface of the instrument panel 442, or above the instrument cover, etc. Sensor 340 can be integrated with the interior components or protruded from the interior components.
[0652] like Figure 57 As shown, the sensor can also be a tactile sensor 500 that detects displacement in three dimensions. The tactile sensor 500 has an operating part 510 including a sponge and a substrate 530 that detects the displacement of the operating part 510. The tactile sensor 500 is capable of detecting displacement in the X direction, displacement in the Y direction orthogonal to the X direction, and displacement in the Z direction orthogonal to both the X and Y directions.
[0653] In this case, the control unit CT3 can also move the robot based on the direction of displacement obtained from the tactile sensor 500. For example, the control unit CT3 can also rotate the robot when the tactile sensor 500 is operated to draw a circle.
[0654] In addition, sponge-type tactile sensors can be embedded in dolls that mimic characters such as cats. The control unit can also identify roll, pitch, and yaw directions in 6-axis directions based on information from the tactile sensors.

[0671] • Heaters installed on the seat back or seat cushion
[0672] • A seat air conditioning unit, also known as a seat blower, that circulates air through the seat cushions and seat back surfaces.
[0673] Vibration devices can be any type of device, including those with a motor and wiring harness that emit vibration, eccentric motors, or linear motors. Vibration devices can be installed in seat cushions, headrests, etc. They can also be installed on the left or right extensions of seat cushions or seat backs.
[0674] The vehicle is not limited to automobiles, but can also be other vehicles, such as two-wheeled vehicles, trams, etc.
