Abstract: An autonomous driving assistance device includes: a determination unit for determining whether or not a driver of a vehicle needs a rest on the basis of detection information of a state of the driver; and a control unit for causing an output device of the vehicle to output a pattern that prompts the driver to sleep through at least one of sight, hearing, or touch during a period in which the vehicle has started moving to a parking area and is parked at the parking area in a case where the determination unit has determined that the driver needs a rest.

Abstract: A notification device includes: an information acquisition unit that acquires driving operation information indicating a driving operation status by a driver of a vehicle; and a notification unit that notifies the driver of a driving operation requested to be executed by the driver during a period from notification of transfer of driving authority from the vehicle to the driver to transfer of the driving authority to the driver. The notification unit notifies the driver of a driving operation, execution of which has not been completed by the driver among the driving operations requested to be executed by the driver on the basis of the driving operation information.

Abstract: There are included a vehicle behavior estimating unit (10) that estimates behavior of a vehicle (1); pattern illuminating units (4a to 4d) that illuminate a projection pattern onto ground around the vehicle (1); and an illumination control unit (11). The illumination control unit (11) controls the pattern illuminating units (4a to 4d) to illuminate a projection pattern, on the basis of the behavior of the vehicle (1) estimated by the vehicle behavior estimating unit (10).

Abstract: A driving assistance apparatus includes: a determination processing unit to determine whether or not a vehicle is present around a target vehicle on the basis of detection information around the target vehicle; and a notification processing unit to notify information to a driver of the target vehicle, in which the notification processing unit notifies reference information of manual driving in a case where the determination processing unit determines that there is no vehicle ahead of the target vehicle.

Abstract: When information regarding a situation inside and outside a vehicle is determined to match a display change condition, a control unit (32) changes a display mode of information displayed outside the vehicle by controlling a projector device (4a) or a body light device (4b).

Abstract: A second light device (4b) starts emission of a light pattern B after a first light device (4a) has started emission of a light pattern A. Elements included in the light pattern B and an element included in the light pattern A are arranged on the same straight line.
