Abstract

A vehicle cabin control device includes: a plurality of seating surface changing devices; a determination unit; and an output unit. The seating surface changing devices is configured to change orientations of seating surfaces of a plurality of vehicle seats. When the determination unit determines that the sharing state is desirable, the output unit operates the seating surface changing devices so as to change orientations of bodies of the occupants to such orientations that the occupants easily communicate with each other. When the determination unit determines that the sharing state is not desirable, the output unit operates the seating surface changing device so as to change an orientation of the body of the occupant to such an orientation that the occupant does not easily communicates with the other occupants.

First claim

What is claimed is:

1. A vehicle cabin control device, comprising:
a plurality of seating surface changing devices configured to change orientations of seating surfaces of a plurality of vehicle seats mounted in a vehicle cabin, the seating surface changing devices include a swivel mechanism configured to swivel the vehicle seat about a vertical direction of a vehicle;
a detection unit configured to detect states of a plurality of occupants sitting on the vehicle seats;
a determination unit configured to determine whether a sharing state is desirable based on a detection result of the detection unit, the sharing state being a state in which the occupants easily communicate with each other; and
an output unit configured to
when the determination unit determines that the sharing state is desirable, operate the swivel mechanism corresponding to the vehicle seats where first occupants are seated so as to swivel the vehicle seats where first occupants are seated inward in a vehicle lateral direction by at least 20 degrees to change orientations of bodies of the first occupants to such orientations that the first occupants easily communicate with each other, the first occupants being occupants for whom the sharing state is desirable, and
when the determination unit determines that the sharing state is not desirable, operate the swivel mechanism corresponding to the vehicle seat where a second occupant is seated so as to swivel vehicle seat where the second occupant is seated outward in the vehicle lateral direction by at least 20 degrees to change an orientation of the body of the second occupant to such an orientation that the second occupant does not easily communicate with the other occupants, the second occupant being an occupant for whom the sharing state is not desirable,

wherein the seating surface changing devices includes a pair of slide pieces that are slidably attached to a pair of slide rail units to slidable attach the plurality of vehicle seats to a floor of the vehicle cabin, the pair of slide pieces and the pair of slide rail units configured to move the plurality of vehicle seats about a vehicle longitudinal direction, and
wherein the output unit is configured to
when the determination unit determines that the sharing state is not desirable, operate the seating surface changing devices corresponding to the vehicle seat where the second occupant is seated to slide the vehicle seat where the second occupant is seated in the vehicle longitudinal direction to change a position of the body of the second occupant to such a position that the second occupant does not easily communicate with the other occupants.

2. The vehicle cabin control device according to claim 1 , wherein each of the seating surface changing devices includes a variable seating surface mechanism configured to change the shape of the seating surface of the vehicle seat.

3. The vehicle cabin control device according to claim 1 , wherein the output unit is configured to operate the seating surface changing devices so that the bodies of all the occupants face inward in the vehicle cabin when the determination unit determines that the sharing state is desirable for all of the occupants.

4. The vehicle cabin control device according to claim 1 , wherein the output unit is configured to, when the determination unit determines that the sharing state is desirable for specific occupants among the occupants, operate the seating surface changing devices corresponding to the vehicle seats where the specific occupants are seated so that the bodies of the specific occupants face inward in the vehicle cabin.

5. The vehicle cabin control device according to claim 1 , wherein the output unit is configured to operate the seating surface changing devices so that the bodies of all the occupants face outward in the vehicle cabin when the determination unit determines that the sharing state is not desirable for any of the occupants.

6. The vehicle cabin control device according to claim 1 , wherein the output unit is configured to, when the determination unit determines that the sharing state is not desirable for a specific occupant among the occupants, operate the seating surface changing device corresponding to the vehicle seat where the specific occupant is seated so that the body of the specific occupant faces outward in the vehicle cabin.

7. The vehicle cabin control device according to claim 1 , wherein:
a plurality of switches configured to be operated by the occupants sitting on the vehicle seats are mounted in the vehicle cabin;
the detection unit is configured to detect an operating state of at least one of the switches; and
the determination unit is configured to determine whether the sharing state is desirable according to the detection result of the detection unit.

8. The vehicle cabin control device according to claim 1 , wherein:
the detection unit is configured to detect speech of at least one of the occupants; and
the determination unit is configured to determine that the sharing state is desirable when the detection unit detects the speech.

9. The vehicle cabin control device according to claim 1 , wherein:
the detection unit is configured to detect states of mobile devices of at least two of the occupants; and
the determination unit is configured to determine that the sharing state is desirable when information is shared between the mobile devices.

10. The vehicle cabin control device according to claim 1 , wherein:
at least one display device is mounted in the vehicle cabin; and
the output unit is configured to, when the determination unit determines that the sharing state is desirable,
display information on the one display device and
operate the seating surface changing devices so that the bodies of the occupants face the display device with information being displayed thereon.

11. The vehicle cabin control device according to claim 1 , wherein:
the detection unit is configured to detect states of mobile devices of at least two of the occupants;
the determination unit is configured to determine that the sharing state is desirable when information is shared between the mobile devices;
at least one display device is mounted in the vehicle cabin; and
the output unit is configured to
when the determination unit determines that the sharing state is desirable, display information on the one display device and operate the seating surface changing devices so that the bodies of the occupants face the display device on which information is displayed, and
when the determination unit determines that information is shared between the mobile devices, display on the display device substantially the same information as the information displayed on the mobile devices sharing the information.

12. The vehicle cabin control device according to claim 1 , wherein:
the detection unit is configured to detect states of mobile devices of at least two of the occupants;
the determination unit is configured to determine whether information is shared between the mobile devices;
at least one display device is mounted in the vehicle cabin; and
the output unit is configured to, when the determination unit determines that information is shared between the mobile devices, display on the display device the same information as the information displayed on the mobile devices sharing the information.

13. The vehicle cabin control device according to claim 1 , wherein:
the detection unit is configured to detect facial expressions of the occupants; and
the determination unit is configured to
estimate emotions of the occupants detected based on the detection result of the detection
