VEHICLE SEAT APPARATUS

1 . A vehicle seat apparatus configured to be mounted on a vehicle capable of traveling on a road, the vehicle seat apparatus comprising:

a seat;

an automatic driving unit that performs automatic driving of the vehicle;

a seat drive configured to drive the seat to transition a position and attitude of the seat between a first mode and a second mode; and

a controller that gives to the seat drive an instruction to transition the position and attitude of the seat from the first mode to the second mode when the controller recognizes that the vehicle travels in a particular section of the road, on a condition that the automatic driving unit performs the automatic driving.

2 . The vehicle seat apparatus according to claim 1 , wherein the controller gives to the seat drive an instruction to automatically return the seat from the second mode to the first mode, on a condition that the controller recognizes that the vehicle is going to travel outside the particular section or the vehicle has traveled outside the particular section.

3 . The vehicle seat apparatus according to claim 2 , further comprising a traveling environment detector that detects a traveling environment of the vehicle,

wherein, on a condition that the traveling environment detector recognizes a particular location in the particular section, the controller gives, before the vehicle reaches the particular location, to the seat drive an instruction to automatically return the seat from the second mode to the first mode.

4 . The vehicle seat apparatus according to claim 2 , further comprising a vehicle outside information detector that detects acquisition of particular vehicle outside information, the particular vehicle outside information being particular information on outside of the vehicle,

wherein, on a condition that the vehicle outside information detector detects the acquisition of the particular vehicle outside information in the particular section ahead of the vehicle in a traveling direction, the controller gives to the seat drive an instruction to automatically return the seat from the second mode to the first mode.

5 . The vehicle seat apparatus according to claim 2 , further comprising a notifying unit that notifies an occupant in the vehicle of information,

wherein, after the notification unit notifies the occupant, as the information, that the controller gives to the seat drive the instruction to automatically return the seat from the second mode to the first mode, the controller gives to the seat drive the instruction to automatically return the seat from the second mode to the first mode.

6 . The vehicle seat apparatus according to claim 3 , further comprising a notifying unit that notifies an occupant in the vehicle of information,

wherein, after the notification unit notifies the occupant, as the information, that the controller gives to the seat drive the instruction to automatically return the seat from the second mode to the first mode, the controller gives to the seat drive the instruction to automatically return the seat from the second mode to the first mode.

7 . The vehicle seat apparatus according to claim 4 , further comprising a notifying unit that notifies an occupant in the vehicle of information,

wherein, after the notification unit notifies the occupant, as the information, that the controller gives to the seat drive the instruction to automatically return the seat from the second mode to the first mode, the controller gives to the seat drive the instruction to automatically return the seat from the second mode to the first mode.

8 . The vehicle seat apparatus according to claim 2 , further comprising a vehicle outside information detector that detects acquisition of particular vehicle outside information, the particular vehicle outside information being particular information on outside of the vehicle,

wherein the vehicle outside information detector detects the acquisition of the particular vehicle outside information in the particular section ahead of the vehicle in a traveling direction,

wherein on a condition that it is difficult for the vehicle to avoid the particular vehicle outside information, the controller prohibits the seat drive from automatically returning the seat from the second mode to the first mode.

9 . The vehicle seat apparatus according to claim 8 , further comprising a notifying unit that notifies an occupant in the vehicle of information,

wherein, the notifying unit notifies the occupant of the particular vehicle outside information which is difficult to avoid, as the information.

10 . A vehicle seat apparatus configured to be mounted on a vehicle capable of traveling on a road, the vehicle seat apparatus comprising:

a seat;

a seat drive configured to drive the seat to transition a position and attitude of the seat between a first mode and a second mode; and

circuitry configured to

perform automatic driving of the vehicle, and

give to the seat drive an instruction to transition the position and attitude of the seat from the first mode to the second mode when the vehicle is recognized to travel in a particular section of the road, on a condition that the automatic driving is performed.
