A restraining device control system includes: a restraining device that is provided at a vehicle seat and that restrains an occupant seated in the vehicle seat; a surrounding environment detection unit that detects an environment surrounding a vehicle; and a control unit that increases a restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that vacillation of the vehicle while in an autonomous driving mode will exceed a threshold amount and that decreases the restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that the vehicle will maintain a state in which vacillation of the vehicle while in the autonomous driving mode is less than the threshold amount.

A leader movable body includes a degree of freedom setting unit configured to set a degree of freedom relevant to movement of a follower movable body, and a transmitter configured to transmit the set degree of freedom to the follower movable body. The follower movable body is configured to perform group travel with respect to the leader movable body.

A vehicle obstacle informing device includes: an obstacle detection section configured to detect an obstacle in surroundings of a vehicle; a gaze detection section configured to detect a gaze direction of an occupant seated in a driving seat; and an informing section configured to make the occupant aware of the obstacle using at least one of display or audio in cases in which the gaze of the occupant as detected by the gaze detection section is directed toward the obstacle during self-driving of the vehicle.

Vehicle obstacle informing device

A sound input/output device for a vehicle includes: sound collecting portions that are provided within a vehicle cabin and that collect voices of vehicle occupants; outputting portions that are provided within the vehicle cabin, and that output sound or images to respective seats; an awakeness degree judging section that judges degrees of awakeness of the vehicle occupants; and an output control section that, in a case in which it is judged, based on a voice collected by the sound collecting portion, that content relating to the vehicle or a vehicle periphery has been spoken, causes information relating to the vehicle or the vehicle periphery to be outputted from each outputting portion that corresponds to a seat in which a vehicle occupant, whose degree of awakeness is higher than a predetermined value, sits.
