Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the prior art, there is a problem that the operation of transmitting a message becomes complicated because the user has to check a plurality of messages displayed on the screen.

[0005] Therefore, an object of the present invention is to simplify the operation of transmitting a message from a first vehicle to a second vehicle.

Means for Solving the Problems

[0006] To solve the above problems, a vehicle system according to the present invention is a system capable of transmitting a message from a first vehicle to a second vehicle. The first vehicle includes at least one sensor and a first control unit. The sensor is provided on an interior member excluding a screen and an operation unit that operates an object on the screen. The sensor detects contact with the user. The first control unit selects one message from a number of pre-stored messages based on information obtained from sensors that changes depending on how the user touches the interior components, and transmits the selected message to the second vehicle.

[0007] With this configuration, when a user touches an interior component in a predetermined way, a message corresponding to the user's touch is sent from the first vehicle to the second vehicle, thus simplifying the process of sending messages.

[0008] Furthermore, the second vehicle includes a display unit capable of displaying characters and a second control unit, and the second control unit may move the characters in an action corresponding to a message received from the first vehicle.

[0009] With this configuration, the characters displayed on the second vehicle's display unit move in accordance with the message, thereby enhancing the entertainment value.

[0010] Furthermore, the interior components may have cushioning.

[0011] Furthermore, the interior components may also be decorative items attached to the first vehicle.

[0012] This configuration allows for the sending of messages when the user touches decorative items, thus enhancing the entertainment value.

[0013] Furthermore, the second vehicle includes a seat, an electric device provided on the seat, and a second control unit, and the second control unit may operate the electric device in accordance with a message received from the first vehicle.

[0014] With this configuration, the electric devices operate in response to messages, which can, for example, enhance entertainment value.

[0015] Furthermore, the electric device is a vibration device that vibrates the seating surface of the seat, and the second control unit may operate the vibration device with a vibration pattern corresponding to a message obtained from the first vehicle.

[0016] Furthermore, the sensor may be a pressure sensor, and the first control unit may select a message based on the pressure value obtained from the pressure sensor.

[0017] Furthermore, the interior components may have lighting, and the first control unit may illuminate the lighting in a lighting pattern corresponding to the selected message.

[0018] Furthermore, the first vehicle includes a first sensor and a second sensor positioned differently from the first sensor, and the first control unit may select a first message based on the signal from the first sensor and a second message different from the first message based on the signal from the second sensor.

[0019] This configuration allows different messages to be sent depending on where the user touches the device.

[0020] Furthermore, the second vehicle includes a first electric device positioned at a location corresponding to a first sensor provided on the first vehicle, a second electric device positioned at a location corresponding to a second sensor provided on the first vehicle, and a second control unit. The second control unit may activate the first electric device when it receives a first message from the first vehicle, and activate the second electric device when it receives a second message from the first vehicle.

[0021] With this configuration, for example, when a user in the first vehicle sends a message using the first sensor, the first electric device located at the position corresponding to the first sensor in the second vehicle is activated, so that the user in the second vehicle can know the location touched by the user in the first vehicle.

[0022] Furthermore, the interior component may be a seat, and the sensor may be positioned to avoid the seating surface of the seat.

[0023] Further, the second vehicle includes a seat, a vibration device that vibrates the seating surface of the seat, and a second control unit. When the first control unit predicts a collision between the first vehicle and the second vehicle based on information from a collision detection unit provided in the first vehicle, the first control unit transmits a collision message for notifying of the vehicle collision to the second vehicle. The second control unit may operate the vibration device in a vibration pattern corresponding to the collision message acquired from the first vehicle.

[0024] According to this configuration, the user of the second vehicle can know the predicted vehicle collision in the first vehicle.

Effect of the Invention

[0025] According to the present invention, when the user touches the interior member in a predetermined way of touching, a message corresponding to the way of touching by the user is transmitted from the first vehicle to the second vehicle, so that the operation of transmitting the message can be simplified.

[0026] Further, by adopting a configuration in which the character displayed on the display unit of the second vehicle moves in an operation corresponding to the message acquired from the first vehicle, the entertainment property can be enhanced.

[0027] Further, by using the interior member as a decorative item, a message is transmitted when the user touches the decorative item, so that the entertainment property can be enhanced.

[0028] Further, by adopting a configuration in which the electric device of the second vehicle is operated in an operation corresponding to the message acquired from the first vehicle, for example, the entertainment property can be enhanced.

[0029] Further, by adopting a configuration in which the first control unit transmits messages corresponding to the first sensor and the second sensor arranged at different positions, different messages can be transmitted according to the position touched by the user.

[0030] Furthermore, the second control unit is configured to operate the first and second electric devices of the second vehicle, which are positioned at locations corresponding to the first and second sensors of the first vehicle, in response to messages from the first vehicle. For example, when a user of the first vehicle sends a message using the first sensor, the first electric device positioned at the location corresponding to the first sensor in the second vehicle is activated, allowing the user of the second vehicle to know the location touched by the user in the first vehicle.

[0031] Furthermore, by configuring the second control unit to activate the vibration device with a vibration pattern corresponding to the collision message acquired from the first vehicle, the user of the second vehicle can become aware of the vehicle collision predicted by the first vehicle.

[0033] [First Embodiment] A first embodiment of the present invention will be described below with reference to the drawings. As shown in Figure 1, the vehicle system 1 is a system capable of sending messages from the first vehicle C1 to the second vehicle C2. The vehicle system 1 comprises the first vehicle C1, the second vehicle C2, and the server SV.

[0034] The first vehicle C1 includes a seat 10, decorative items 20 as an example of interior components, a camera 30 as an example of a collision detection unit, a monitor M as an example of a display unit, and a control unit 100. The seat 10, decorative items 20, camera 30, and monitor M are located inside the first vehicle C1, specifically in a position facing the passenger compartment. In this embodiment, the seat 10 is the driver's seat.

[0035] The seat 10 comprises a seat body 10A and a vibration device 70 as an example of an electric device.

[0036] The seat body 10A is a component having a seating surface that supports the user. The seat body 10A comprises 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 that forms the skeleton, a pad that covers the frame, and a surface covering that covers the pad. The pad is made of urethane foam or the like. The surface covering is made of synthetic leather or fabric or the like. The top surface of the seat cushion 11 is the seating surface. The front surfaces of the seat back 12 and the headrest 13 are seating surfaces.

[0037] The vibration device 70 is a device that vibrates the seating surface of the seat 10. In this embodiment, the vibration device 70 is provided on the seat back 12. For example, one vibration device 70 is provided on the left side and one on the right side of the seating surface of the seat back 12.

[0038] As shown in Figure 2, the ornament 20 is a cat plush toy. The ornament 20 is mounted on the dashboard D of the first vehicle C1. The ornament 20 has a sensor 21, a light 22, a cushion 23, and a surface 24.

[0039] Sensor 21 is a pressure sensor that detects contact between the ornament 20 and the user. Sensor 21 is located on the body portion of the ornament 20. The position of sensor 21 is arbitrary; for example, sensor 21 may be located on the head of the ornament 20.

[0040] The light 22 is capable of emitting light of several different colors. The light 22 is located, for example, between the cushion 23 and the skin 24. The light 22 emits light to the outside through holes or transparent parts provided in, for example, the skin 24. The light 22 is located on the body portion of the ornament 20. The position of the light 22 is arbitrary; for example, a sensor 21 may be placed on the head of the light 22. The light 22 may also be located on the outer surface of the skin 24.

[0041] The cushion 23 is made of urethane foam or similar material and covers the sensor 21. The outer shape of the cushion 23 is modeled after a cat. The outer layer 26 is made of synthetic leather or fabric and covers the cushion 23.

[0042] Monitor M has a screen M1 that displays an image. The image displayed on Monitor M can be changed by the control unit 100. Monitor M can be positioned on the dashboard D, for example, below the rearview mirror.

[0043] Returning to Figure 1, camera 30 is a camera that photographs the area in front of the first vehicle C1. The image information captured by camera 30 is output to the control unit 100.

[0044] The control unit 100 has a CPU, ROM, RAM, rewritable non-volatile memory, etc. (not shown), and executes a pre-stored program. The control unit 100 acquires information from the camera 30 and the sensor 21 in the ornament 20. The control unit 100 controls the monitor M and the vibration device 70. The control unit 100 is capable of communicating with the server SV.

[0045] The second vehicle C2 is equipped with the same seats 10, decorative items 20, cameras 30, monitor M, and control unit 100 as the first vehicle C1. The control unit 100 of the second vehicle C2 can communicate with the control unit 100 of the first vehicle C1 via the server SV. In the following description, the control unit 100 of the first vehicle C1 will also be referred to as the "first control unit 110," and the control unit 100 of the second vehicle C2 will also be referred to as the "second control unit 120."

[0046] The functions of the first control unit 110 and the second control unit 120 are described below. Since the first control unit 110 and the second control unit 120 have the same functions, the functions described for one of them are also present in the other.

[0047] The first control unit 110 has the function of selecting one message from a plurality of pre-stored messages based on information (pressure value) acquired from the sensor 21, and transmitting the selected message to the second control unit 120 (control unit 100 of the second vehicle C2). Here, the information acquired by the sensor 21 changes depending on how the user touches the decorative item 20. The first control unit 110 selects a message from a plurality of messages that corresponds to how the user touches the item.

[0048] In this embodiment, the first control unit 110 selects a message according to the number of times the user rubs the ornament 20 within a predetermined time (hereinafter also referred to as the "input count"). Specifically, the first control unit 110 increments the input count by one when the pressure value obtained from the sensor 21 becomes equal to or greater than a predetermined value, and thereafter increments the input count each time the pressure value rises from a value less than the predetermined value to a value greater than or equal to the predetermined value within a predetermined time.

[0049] The first control unit 110 selects the first message, "Thank you for letting me pass," if there is one input within a predetermined time. The first control unit 110 selects the second message, "I'm sorry," if there are two inputs within a predetermined time. The first control unit 110 selects the third message, "I'm changing lanes," if there are three inputs within a predetermined time.

[0050] Note that lane changes can occur from the left lane to the right lane or from the right lane to the left lane, but in this embodiment, only the case of changing from the left lane to the right lane will be described as representative. When changing from the right lane to the left lane, for example, the first control unit 110 may be configured to select a message indicating a change from the right lane to the left lane when the number of inputs within a predetermined time is four.

[0051] When the second control unit 120 receives the first message from the first control unit 110, it displays an image of the text representing the first message and a cat character on the screen M1 of the monitor M, as shown in Figure 3. The second control unit 120 then moves the character in an action corresponding to the first message received from the first control unit 110. For example, the second control unit 120 displays an image of the text "Thank you for letting me have it" along with a video of the cat bowing.

[0052] When the second control unit 120 receives a second message from the first control unit 110, it displays an image of the characters representing the second message and a video of a cat performing an action corresponding to the second message on the monitor M's screen M1, as shown in Figure 4. For example, the second control unit 120 displays an image of the characters "I'm sorry" along with a video of a cat bowing its head in apology.

[0053] When the second control unit 120 receives a third message from the first control unit 110, it displays an image of the text representing the third message and a video of a cat performing an action corresponding to the third message on the monitor M's screen M1, as shown in Figure 5. For example, the second control unit 120 displays an image of the text "Changing lanes" along with a video of a cat crossing the road.

[0054] Furthermore, the first control unit 110 has a function to illuminate the lighting 22 with a lighting pattern corresponding to the selected message. For example, if the first message is selected, the first control unit 110 will emit red light from the lighting 22. If the second message is selected, the first control unit 110 will emit blue light from the lighting 22. If the third message is selected, the first control unit 110 will emit yellow light from the lighting 22. Note that the lighting pattern is not limited to color; for example, it may be a lighting pattern with different blinking intervals.

[0055] The second control unit 120 has the function of, when it receives a message from the first control unit 110, lighting up the lights 22 with a lighting pattern corresponding to the received message, and operating the vibration device 70 with a vibration pattern corresponding to the received message. The lighting pattern can be, for example, the same as the pattern used when the first control unit 110 selects a message.

[0056] The vibration patterns can be set to different patterns, for example, in which the vibration device 70 operates the most times. For example, the vibration pattern corresponding to the first message can be set to a pattern in which at least one of the left or right vibration devices 70 vibrates twice during a second predetermined time. The vibration pattern corresponding to the second message can be set to a pattern in which at least one of the left or right vibration devices 70 vibrates six times during a second predetermined time. The vibration pattern corresponding to the third message can be set to a pattern in which the vibration moves from left to right by activating the left vibration device 70 first, and then the right vibration device 70.

[0057] Furthermore, the first control unit 110 has a function to predict a collision between the first vehicle C1 and the second vehicle C2 based on information from the camera 30. When the first control unit 110 predicts a collision between the first vehicle C1 and the second vehicle C2, it sends a collision message to the second control unit 120 to warn of the vehicle collision. The collision message could be, for example, "There is a possibility that the following vehicle will rear-end your vehicle."

[0058] The second control unit 120 has a function to activate the vibration device with a vibration pattern corresponding to the collision message received from the first control unit 110. The vibration pattern corresponding to the collision message can be set, for example, to a pattern that causes the vibration device 70 to vibrate continuously for a second predetermined time or longer.

[0059] Next, the operation of the first control unit 110 and the second control unit 120 will be described in detail. The first control unit 110 repeatedly executes the transmission process shown in Figure 6.

[0060] In the transmission process, the first control unit 110 transmits the location information of the first vehicle C1, along with the vehicle ID (identification information) of the first vehicle C1, to the server SV using GPS (Global Positioning System) or the like (S1). Here, the second control unit 120, which has the same function as the first control unit 110, also constantly transmits the vehicle ID and location information of the second vehicle C2 to the server SV. The server SV associates the vehicle ID and location information for each vehicle and updates it constantly.

[0061] After step S1, the first control unit 110 obtains the vehicle ID and location information of the other vehicle from the server SV (S2). After step S2, the first control unit 110 determines, based on the vehicle ID and location information obtained in step S2, whether or not the second vehicle C2 exists in the vicinity of the first vehicle C1 (for example, within a radius of several tens of meters) (S3).

[0062] If it is determined in step S3 that the second vehicle C2 does not exist (No), the first control unit 110 terminates this process. If it is determined in step S3 that the second vehicle C2 exists (Yes), the first control unit 110 determines whether or not information has been input to the sensor 21 by determining whether or not the pressure value obtained from the sensor 21 is equal to or greater than a predetermined value (S4).

[0063] If step S4 determines that information has been input to the sensor 21 (Yes), the first control unit 110 calculates the number of inputs to the sensor 21 within a predetermined time and selects a message and lighting pattern based on the calculated number of inputs (S5). After step S5, the first control unit 110 lights up the lights 22 of the decorative item 20 with the selected lighting pattern (S6).

[0064] After step S6, the first control unit 110 transmits the selected message to the second vehicle C2 via the server SV (S7). After step S7, the first control unit 110 acquires information from the camera 30 (S8). If it is determined in step S4 that there is no information input to the sensor 21 (No), the control unit 51 skips steps S5 to S7 and proceeds to the processing in step S8.

[0065] After step S8, the first control unit 110 determines, based on the information acquired from the camera 30, whether or not there is a possibility of collision between the first vehicle C1 and the second vehicle C2 (S9). If it is determined in step S9 that there is a possibility of collision (Yes), the first control unit 110 sends a collision message to the second control unit 120 of the second vehicle C2 (S10) and terminates this process. If it is determined in step S9 that there is no possibility of collision (No), the first control unit 110 terminates this process as is.

[0066] The second control unit 120 repeatedly executes the reception process shown in Figure 7. In the reception process, the second control unit 120 determines whether or not it has received a message from the first vehicle C1 (S31). If it determines in step S31 that no message has been received (No), the second control unit 120 terminates this process.

[0067] If it is determined in step S31 that a message has been received (Yes), the second control unit 120 selects a cat action, vibration pattern, and lighting pattern based on the received message (S32). After step S32, the second control unit 120 displays the received message and a video of the cat performing the selected action on screen M1 (S33).

[0068] After step S33, the second control unit 120 activates the vibration device 70 with the selected vibration pattern (S34) and turns on the lights 22 of the decorative item 20 with the selected lighting pattern (S35), and then terminates the process.

[0069] Next, a specific example of the operation of the control unit 100 will be described. As shown in Figure 8, for example, in a situation where vehicle C1 overtakes vehicle C2, which has yielded the right of way to vehicle C1 by changing lanes, if the user of vehicle C1 rubs the ornament 20 once, the first message is sent from vehicle C1 to vehicle C2. When the second control unit 120 receives the first message, it displays an image on screen M1 expressing gratitude to the user of vehicle C2.

[0070] This allows the user in the first vehicle C1 to send a first message of gratitude to the second vehicle C2 simply by performing an action such as rubbing the decorative item 20 once. The user in the second vehicle C2 can then feel that they have performed a good deed by seeing the words of gratitude and the video of the cat bowing displayed on screen M1.

[0071] Furthermore, when the first message is sent from the first vehicle C1 to the second vehicle C2, both the decorative item 20 in the first vehicle C1 and the decorative item 20 in the second vehicle C2 light up red. This allows the user who sent the message and the user who received it to intuitively know that they have sent or received a message expressing gratitude by seeing the red-lit decorative item 20.

[0072] Furthermore, in seat 10 of the second vehicle C2, the vibration device 70 vibrates twice. This allows the user who receives the message to intuitively know that they have received a message expressing gratitude.

[0073] For example, in a situation where the first vehicle C1 suddenly cuts in front of the second vehicle C2, if the user of the first vehicle C1 rubs the ornament 20 twice, the second message is sent from the first vehicle C1 to the second vehicle C2. When the second control unit 120 receives the second message, it displays an image on screen M1 to apologize to the user of the second vehicle C2, as shown in Figure 4.

[0074] This allows the user in the first vehicle C1 to send a second apology message to the second vehicle C2 simply by performing an action such as rubbing the decorative item 20 twice. In addition, the user in the second vehicle C2 will find their anger eased by the apology text and the video of the bowing cat displayed on screen M1.

[0075] Furthermore, when the second message is sent from the first vehicle C1 to the second vehicle C2, both the decorative item 20 in the first vehicle C1 and the decorative item 20 in the second vehicle C2 light up blue. This allows the user who sent the message and the user who received it to intuitively know that they have sent or received a message expressing apology by seeing the decorative item 20 light up blue.

[0076] Furthermore, in seat 10 of the second vehicle C2, the vibration device 70 vibrates six times. This allows the user who receives the message to intuitively know that they have received a message expressing an apology.

[0077] For example, when the first vehicle C1 changes lanes, if the user of the first vehicle C1 rubs the decorative item 20 three times, the third message is sent from the first vehicle C1 to the second vehicle C2. When the second control unit 120 receives the third message, it displays an image on screen M1 to inform the user of the second vehicle C2 of the lane change, as shown in Figure 5.

[0078] This allows the user of the first vehicle C1 to send a third message to the second vehicle C2, indicating a lane change, simply by performing an action such as rubbing the decorative item 20 three times. The user of the second vehicle C2 can also be soothed by the text indicating the lane change and the cat video displayed on screen M1.

[0079] Furthermore, when the third message is sent from the first vehicle C1 to the second vehicle C2, both the decorative item 20 of the first vehicle C1 and the decorative item 20 of the second vehicle C2 light up yellow. Also, in the seat 10 of the second vehicle C2, the left vibration device 70 vibrates first, followed by the right vibration device 70. This allows the user who receives the message to know that the vehicle is changing lanes from the left lane to the right lane.

[0080] As described above, the following effects can be obtained according to this embodiment. When a user touches the decorative item 20 in a predetermined manner, a message corresponding to the user's touch is sent from the first vehicle C1 to the second vehicle C2, thus simplifying the process of sending messages.

[0081] The cat character displayed on monitor M in the second vehicle C2 moves in response to the message, enhancing the entertainment value.

[0082] Since a message is sent when the user touches the decorative item 20, the entertainment value can be enhanced.

[0083] The vibration device 70 operates in response to the message, allowing users to intuitively understand the message through the vibration pattern.

[0084] The lights illuminate in patterns corresponding to the message, allowing users to intuitively understand the message through the lighting patterns.

[0085] Since the vibration device 70 operates with a vibration pattern corresponding to the collision message, the user of the second vehicle C2 can be aware of the vehicle collision predicted in the first vehicle C1.

[0086] [Second Embodiment] Next, a second embodiment of the present invention will be described in detail with reference to the drawings as appropriate. Since this embodiment modifies some of the configuration of the vehicle system 1 and some of the operation of the control unit 100 compared to the first embodiment, the same reference numerals are used for components and processes as in the first embodiment, and their descriptions will be omitted.

[0087] As shown in Figure 9, the vehicle system 601 according to the second embodiment includes a seat 610 as an example of an interior component. The seat 610 includes a seat body 610A having substantially the same configuration as the seat body 10A of the first embodiment, a first vibration device 671 and a second vibration device 672 having substantially the same configuration as the vibration device 70 of the first embodiment, and further includes a first sensor 41 and a second sensor 42.

[0088] Figure 9 illustrates the configuration provided in the first vehicle C1, but this configuration is also provided in the second vehicle C2. Furthermore, in the second embodiment, the first vehicle C1 and the second vehicle C2 do not have the decorative item 20 of the first embodiment.

[0089] The seat cushion 11 has a base portion 11A positioned in the center left and right, and protruding portions 11B positioned on both the left and right sides of the base portion 11A. The base portion 11A has a seating surface F that contacts and supports the user's buttocks and thighs from below. The protruding portions 11B extend from the seating surface F of the base portion 11A toward the user to support the sides of the user's thighs and buttocks.

[0090] Similarly, the seatback 12 also has a base portion 12A positioned in the center left and right, and protruding portions 12B positioned on both the left and right sides of the base portion 12A. The base portion 12A has a seating surface F that contacts the user's back and supports it from behind. The protruding portions 12B extend from the seating surface F of the base portion 12A toward the user in order to support the sides of the user's upper body.

[0091] The seat cushion 11 has a first vibration device 671 and a first sensor 41. The headrest 13 has a second vibration device 672 and a second sensor 42.

[0092] The first sensor 41 and the second sensor 42 are pressure sensors that detect pressure from the user. The first sensor 41 and the second sensor 42 are installed in positions that avoid the seating surface F, that is, at positions away from the seating surface F.

[0093] More specifically, the first sensor 41 is provided on each of the left and right protruding portions 11B of the seat cushion 11. The second sensor 42 is located in a different position from the first sensor 41. Specifically, there is one second sensor 42 on each of the left and right sides of the headrest 13. The first sensor 41 and the second sensor 42 are each located between the surface and the pad.

[0094] The first vibration device 671 is positioned in a location corresponding to the first sensor 41 (near the first sensor 41). In other words, the first vibration device 671 and the first sensor 41 are provided on the same component (seat cushion 11).

[0095] More specifically, two first vibration devices 671 are provided side-by-side within the base portion 11A of the seat cushion 11. Each first vibration device 671 is located between the left and right first sensors 41. By positioning the first vibration devices 671 in positions (members) corresponding to the first sensors 41, the second vehicle C2, which has the same seat 610 as the first vehicle C1, will be equipped with first vibration devices 671 positioned in positions corresponding to the first sensors 41 provided in the first vehicle C1.

[0096] The second vibration device 672 is positioned in a location corresponding to the second sensor 42 (or near the second sensor 42). In other words, the second vibration device 672 and the second sensor 42 are located on the same component (headrest 13).

[0097] More specifically, two second vibration devices 672 are provided side-by-side within the headrest 13. Each second vibration device 672 is located between the left and right second sensors 42. By positioning the second vibration devices 672 in positions (members) corresponding to the second sensors 42, the second vehicle C2, which has the same seat 610 as the first vehicle C1, will be equipped with second vibration devices 672 positioned in positions corresponding to the second sensors 42 provided in the first vehicle C1.

[0098] The first control unit 110 can acquire information from the first sensor 41 and the second sensor 42. Based on the signal from the first sensor 41, the first control unit 110 selects a first message, and based on the signal from the second sensor 42, it selects a second message that is different from the first message. In the second embodiment, the contents of the first message and the second message are the same as in the first embodiment.

[0099] The second control unit 120, which is the control unit 100 of the second vehicle C2, activates the first vibration device 671 of the second vehicle C2 when it receives a first message from the first vehicle C1. The second control unit 120 activates the second vibration device 672 of the second vehicle C2 when it receives a second message from the first vehicle C1.

[0100] The first control unit 110 executes the process shown in Figure 10. The process in Figure 10 includes steps S1 to S3 and S7 to S10 of the process in Figure 6, as well as new steps S51 to S54.

[0101] If the first control unit 110 determines in step S3 that a second vehicle C2 is present in the vicinity of its own vehicle (Yes), it determines whether or not information has been input to the first sensor 41 (S51). If the first control unit 110 determines in step S51 that information has been input to the first sensor 41 (Yes), it selects the first message (S52).

[0102] If step S51 determines that no information has been input to the first sensor 41 (No), the first control unit 110 determines whether or not information has been input to the second sensor 42 (S53). If step S53 determines that information has been input to the second sensor 42 (Yes), the first control unit 110 selects the second message (S54).

[0103] If the first control unit 110 determines in step S53 that there is no information input to the second sensor 42 (No), the first control unit 110 proceeds to the processing in step S8. After step S52 or step S54, the first control unit 110 transmits the selected message to the second vehicle C2 (S7).

[0104] The second control unit 120 executes the process shown in Figure 11. The process in Figure 11 includes steps S31 and S33 in the process in Figure 7, as well as new steps S71 and S72.

[0105] If the second control unit 120 determines that it has received a message in step S31 (Yes), it selects an action for the cat and a vibration device to activate based on the message (S71). After step S71, the second control unit 120 displays the received message and a video of the cat performing the selected action on screen M1 (S33). After step S33, the second control unit 120 activates the selected vibration device (S72) and terminates this process.

[0106] Next, a specific example of the operation of the control unit 100 will be described. As shown in Figure 12, for example, in a situation where the first vehicle C1 suddenly cuts in front of the second vehicle C2, if the user of the first vehicle C1 presses either the left or right side of the headrest 13, the second message is sent from the first vehicle C1 to the second vehicle C2. When the second control unit 120 receives the second message, it displays an image on screen M1 to apologize to the user of the second vehicle C2 and vibrates the second vibration device 672 of the headrest 13.

[0107] This allows the user of the first vehicle C1 to send a second message of apology to the second vehicle C2 simply by performing a simple operation, such as pressing the side of the headrest 13. Furthermore, when the user of the first vehicle C1 presses the headrest 13, the headrest 13 in the second vehicle C2 vibrates, allowing the user of the second vehicle C2 to know the location (part) that the user of the first vehicle C1 touched. As a result, the user of the first vehicle C1 and the user of the second vehicle C2 can interact with each other through the seat 610.

[0108] For example, in a situation where vehicle C2, which is driving in front of vehicle C1, changes lanes to let vehicle C1 pass, if the user of vehicle C1 presses either the left or right protruding part 11B of the seat cushion 11, the first message is sent from vehicle C1 to vehicle C2. When the second control unit 120 receives the first message, as shown in Figure 3, it displays an image on screen M1 expressing gratitude to the user of vehicle C2, and also vibrates the first vibration device 671 of the seat cushion 11.

[0109] As a result, the user of the first vehicle C1 can send a first message of gratitude to the second vehicle C2 simply by performing a simple operation, such as pressing the protruding part 11B of the seat cushion 11. Furthermore, when the user of the first vehicle C1 presses the seat cushion 11, the seat cushion 11 in the second vehicle C2 vibrates, allowing the user of the second vehicle C2 to know the location (part) that the user of the first vehicle C1 touched. Therefore, the user of the first vehicle C1 and the user of the second vehicle C2 can interact with each other through the seat 610.

[0110] The seat is not limited to the structure of the embodiment described above. For example, as shown in Figure 13, the seat 200 may have a seat cushion 210, a seat back 220, and a headrest 230, as well as an ottoman 240 and an armrest 250. A console box 300 may also be provided next to the seat 200.

[0111] In the configuration shown in Figure 13, the seat back 220 includes a first member 221 that is rotatably supported by the seat cushion 210, and a second member 222 that is rotatably supported on the upper part of the first member 221 and has a headrest 230 provided on its upper part.

[0112] In this case, the sensor 40, which receives information from the user, can be placed in at least one of the following locations. • Left and right protruding parts 211 of the seat cushion 210 • Front end surface of seat cushion 210 • Left and right protruding portions 221A of the first member 221 • Left and right protruding portions 222A of the second member 222 • The left and right sides or back of the seatback 220 • The left and right sides, bottom, or back of the headrest 230 • Front end surface, top surface, left and right inner sides, or left and right outer sides of the armrest 250 • Left and right sides of the 240cm ottoman • The left and right inner sides or left and right outer sides of the console box 300

[0113] The sensor 40 may be the first sensor 41, the second sensor 42, or any other sensor for transmitting a message different from that of the first sensor 41 and the second sensor 42.

[0114] Furthermore, as shown in Figure 14, the sensor 40 may be provided on the steering wheel ST, as indicated by the dot hatching in the figure. The screen M1 on which the character is displayed may also be provided on the steering wheel ST.

[0115] As shown in Figure 15, the sensor 40 may be installed in the center console box 401 located between the driver's seat and the passenger seat, the dashboard 402, or an inner panel 403 such as a door or the side wall of the vehicle, as indicated by the dot hatching in the figure. The sensor 40 may also be installed inside a cylindrical blower 404. The cylindrical blower 404 has a cylindrical body with an air outlet for sending air into the vehicle.

[0116] Furthermore, as shown in Figure 16, the sensor 40 may be provided on a component (seat cushion, seat back, headrest) that makes up at least one of the first-row seat 411, the second-row seat 412, or the third-row seat 413, as indicated by the dot hatching in the figure. The sensor 40 may also be provided on the roof 414, the cover 415 for opening and closing the sunroof, the assist grip 416, the upper part of the back of the seat back, the upper surface of the dashboard 402, or above the meter hood. The sensor 40 may be integrated inside the interior component, or it may be positioned protruding from the interior component.

[0117] As shown in Figure 17, the sensor may be a tactile sensor 500 that detects displacement in three dimensions. The tactile sensor 500 has an operating part 510 made of sponge and a substrate 520 that detects the displacement of the operating part 510. The tactile sensor 500 can detect displacement in the X direction, displacement in the Y direction perpendicular to the X direction, and displacement in the Z direction perpendicular to both the X and Y directions.

[0118] In this case, the control unit 100 may select a message based on the direction of displacement obtained from the tactile sensor 500. For example, the control unit 100 may select a message expressing gratitude if the tactile sensor 500 is operated to draw a circle.

[0119] Furthermore, the sponge-type tactile sensor may be embedded in stuffed animals or other objects that resemble characters such as cats. Based on the information from the tactile sensor, the control unit may recognize the roll, pitch, and yaw directions corresponding to the six axes. For example, when the control unit detects an input pattern of roughly touching a stuffed animal (a movement of holding the stuffed animal with both hands and moving both hands up and down), it may select a message expressing gratitude. Alternatively, for example, the control unit may control multiple air cells to reproduce the rough touching motion on the surface of the seat in the second vehicle.

[0120] In this case, the first control unit may select the message "Thank you" when it determines that strong pressure has been applied to the right side of the stuffed animal. The first control unit may select the message "I'm sorry" when it determines that strong pressure has been applied to the left side of the stuffed animal. The first control unit may select the message "I'll go first" when it determines that the stuffed animal has been kneaded multiple times. The first control unit may select the message "I'll go first" when it determines that the stuffed animal has been pinched.

[0121] The first control unit may decide whether or not to send the selected message based on information from the sensor. For example, a transmission sensor may be provided on the top of the stuffed animal, and the selected message may be sent when the transmission sensor is tapped twice.

[0122] The electric device may be one of the following devices. • Reclining device that tilts the seatback • Height mechanism that allows the seat to move up and down. • A sliding device that moves the seat back and forth. A movable device that deforms the sheet shape by driving a bag (air cell) or plate member that is operated by introducing air. - Side frame front end raising mechanism that switches between an raised position and a lowered position for the front end of the seat cushion's side frame. • Tilt mechanism that moves the seat cushion's cushion pan up and down. • A folding mechanism that tilts the upper part of the seat back forward and backward (a mechanism that tilts the second member 222 in Figure 13 relative to the first member 221). • Rotation mechanism that rotates the seat on a vertical axis • Cushion front-to-back adjustment mechanism to adjust the length of the front end of the seat cushion. • Mechanism for rotating the ottoman up and down • Mechanism for rotating the armrest up and down • Mechanism for extending and retracting the armrest • Mechanism to switch between extended and bent armrest positions ·illumination • Headrest speakers (The headrest speakers may rotate or move in at least one direction: forward, backward, left, right, up, or down.) • Heater located in the seat back or seat cushion • Seat blower: A seat air conditioning device that circulates air across the surface of the seat cushion and seat back.

[0123] The movable device may be one that moves the left and right protruding parts of the seat cushion or seat back, or one that moves a part of the seating surface of the seat back or seat cushion.

[0124] The air cells are connected by an air pump and an air tube, and when air is injected, they may inflate towards the occupant and press against the occupant. The air cells may be positioned to correspond to the occupant's lower back, such as a lumbar support, or they may be provided at multiple locations on the seat.

[0125] The vibration device may be installed on the seat cushion or the protruding part of the seat back.

[0126] The vibration device may be any type, such as one having a motor and harness that generate vibrations, one having an eccentric motor, or one having a linear motor.

[0127] The display unit may be located in any position, such as on the instrument panel, center console, steering wheel, meter, seat back, door side, or decorative elements. The display unit may also be a projection device that projects images. Furthermore, the display unit may be a mobile device such as a smartphone or tablet held by the occupant.

[0128] If a sensor is installed on the protruding part of the seat, for example, the control unit may, when it detects a pinching motion of the protruding part with a hand, select a warning message and tilt the seat back slightly backward.

[0129] Alternatively, the number of inputs to the sensor per predetermined time period before the character display action begins may be measured, and the character display pattern may be determined according to the number of inputs.

[0130] Interior components may include doors, door armrests, steering wheel, dashboard, center console, and air conditioning vents.

[0131] The interior components may be parts that mimic animal body parts, such as cat ears. The interior components may also be made of a napped material.

[0132] The sensor may be a capacitive touch sensor. The touch sensors may be provided, for example, on the front end of the seat cushion, the protruding part of the seat cushion, the protruding part of the seat back, and the side of the headrest.

[0133] The interior lighting color tone, screen display, and sound may be changed depending on the duration of time the touch sensor is touched. The operating pattern of the oscillator may be changed according to the pressure value input to the touch sensor.

[0134] The control unit may move the vibrator more strongly the harder the touch sensor is pressed. The control unit may also increase the speed of the vibrator's movement the faster the speed at which the touch sensor is stroked.

[0135] The characters can be animals other than cats, or they can be anthropomorphic representations of objects or living things. The characters can be pre-configured and, for example, they can be stylized images of the crew members.

[0136] The vehicle is not limited to automobiles; it may also include other vehicles such as motorcycles or trains.

[0137] The collision detection unit may also be a distance sensor that detects the distance between the vehicle and the vehicle in front.

[0138] The first or second sensor may be a sensor that detects biological information (at least one of the following: brain waves, facial expressions, gaze, respiration, heart rate, pulse, voice, etc.).

[0139] Examples of methods for manufacturing vehicle interior systems include the following: A vehicle system capable of sending a message from a first vehicle to a second vehicle, wherein the first vehicle comprises an interior component, excluding a screen and an operating unit for operating objects on the screen, and includes at least one sensor for detecting contact with a user, and a first control unit, wherein the first control unit selects one message from a plurality of pre-stored messages based on information obtained from the sensor that changes depending on how the user touches the interior component, and transmits the selected message to the second vehicle, the manufacturing method of the vehicle interior system comprising the steps of: attaching the sensor to the interior component; attaching the interior component and the first control unit to the first vehicle; and connecting the sensor to the control unit.

[0140] Vehicle 1 and Vehicle 2 may communicate directly without going through a server.

[0141] The interior components can be any type of interior component, excluding the screen and the control unit used to operate objects on the screen.

[0142] There may be multiple second vehicles capable of communicating with the first vehicle. In this case, it may be possible to select the recipient of the message. Examples of methods for determining the recipient include the following: • A method that uses a camera to capture the crew's gestures (pointing direction, hand movements indicating forward, backward, left, right, or diagonal directions) and determines the recipient based on the information from the camera. A method of determining the recipient of a transmission based on information from switches or sensors (which may have cursor buttons or a sensor unit for determining direction) that allow input of forward, backward, left, right, and diagonal directions.

[0143] Furthermore, when determining the recipient using gestures or similar methods, it is advisable to also use the location information of each of the multiple second vehicles. For example, the first control unit can determine the direction from its own vehicle to each second vehicle based on the location information of its own vehicle and the location information of each second vehicle, and then determine the second vehicle to which this direction matches the direction specified by the occupant, which is determined from information such as camera data, as the message recipient.

[0144] Message patterns may be set for each category, such as "greetings," "gratitude," "apologies," "road conditions," and "vehicle movements (yielding)." The sensor input pattern is not based on text input, but on variations in how the sensor is touched. In other words, a message is generated with a single touch, and no input is required via the display unit.

[0145] The association between message patterns and sensors can also be configured in advance. For example, when selecting the "thank you" message, the user can choose from several ways to interact with the sensor (interior component), such as applying strong pressure to the sensor (direction and strength of pressure), drawing a circle around the sensor (a method of interacting with an electrostatic sensor), or touching the sensor on the door (location of the sensor).

[0146] Additionally, a cat could perform an action of stroking its cheek in response to a "thank you" message, or a cat could shrink back in response to a "I'm sorry" message. Displaying character actions in addition to text on the screen can create a sense of familiarity.

[0147] Additionally, in response to the message "Thank you," an action of a cat stroking the cheek may be displayed, and the air cells in the recipient's seat may operate softly. In response to the message "I'll let you go first," the vibration device in the recipient's seat back may vibrate. In response to the message "Thank you for your hard work," the recipient's air conditioning system may operate the vents to blow air towards the occupant in the driver's seat.

[0148] In response to the message "Please go ahead," multiple vibration devices may transmit wave-like motion patterns to the other vehicle. In response to the message "I'm changing lanes," the vibration device may transmit vibrations to the other vehicle at a location corresponding to the direction of the transmitting vehicle's position (for example, when moving from the right lane to the left lane, the right side of the seat in the other vehicle may vibrate).

[0149] The air cell is connected by an air pump and an air tube, and may inflate and press towards the occupant when air is injected. The air cell may be located in the lumbar region, like a lumbar support, or multiple air cells may be provided to allow for more localized shape modification.

[0150] The ornament may have a vibration device. When the second vehicle receives a message, the ornament on the second vehicle may vibrate.

[0151] In the above embodiment, the lighting color that changes in response to the message was set to "red" for "thank you" type messages and "blue" for "apology" type messages, but the color assignment for each message can be set arbitrarily.

[0152] The first control unit may select a message based on the change in force input to the sensor (the magnitude of the pressure applied to the sensor). For example, the first control unit may select the message "I'm sorry" if strong pressure is applied to the sensor. The first control unit may select the message "I'll let you go first" if the sensor is squeezed multiple times.

[0153] The relationship between how the sensor is touched and the message it sends can be configured as desired. For example, the first control unit may select the message "Sorry" if a force is applied to the sensor in the forward or backward direction. The first control unit may also select the message "I'll let you go first" if a force is applied to the sensor in the left or right direction.

[0154] The first control unit may select a message based on the number of fingers touching the sensor. For example, if a force is applied to the sensor in the forward and backward direction with three fingers, the message "Thank you" may be selected. In addition, the second control unit may increase the heater temperature of the other vehicle in response to the "Thank you" message, or it may activate the vibration device of the other vehicle in response to the "Thank you" message.

[0155] The first control unit may select a message based on the number of times force is applied to the sensor within a predetermined time (number of inputs within a predetermined time). For example, the first control unit may select the message "I'm sorry" if the sensor receives multiple inputs quickly (for example, three times per second). Alternatively, the first control unit may select the message "Thank you" if the sensor receives inputs slowly (for example, once per second).

[0156] Furthermore, the mounting positions of the multiple sensors are arbitrary. In this case, for example, the first control unit may select the message "Thank you" when the user touches the sensor on the side of the headrest. The first control unit may select the message "I'm sorry" when the user touches the sensor on the top surface of the headrest. The first control unit may select the message "Not at all" when the user touches the sensor on the back of the headrest. The first control unit may select the message "I'll go first" when the user touches the sensor on the door.

[0157] When the second control unit receives the first message, it may activate an electric device that is not located in a position corresponding to the first sensor provided in the first vehicle. For example, if the first sensor is located in the seat cushion, the second control unit may activate a vibration device located in the headrest when it receives the first message.

[0158] The type of message may be the direction of travel of the vehicle. Lighting may be provided in the doors. The control unit may change the intensity of the light.

[0159] The first control unit may, based on the selected message, select the action of the character to be moved on the screen of the second vehicle, the vibration pattern of the vibration device of the second vehicle, and the lighting pattern of the lights of the second vehicle. In this case, the first control unit may transmit the message, action, vibration pattern, and lighting pattern to the second control unit, and the second control unit may, based on the received message, action, vibration pattern, and lighting pattern, display the screen, operate the vibration device, and turn on the lights.

[0160] The elements described in the above embodiments and modifications may be implemented in any combination. [Explanation of Symbols]
