## Abstract

An autonomous driving vehicle information presentation device includes a traffic congestion information acquisition unit that acquires information on traffic congestion ahead in a traveling direction of an own vehicle, a traveling lane identification unit that identifies a lane where the own vehicle is currently located, a stop position prediction unit that acquires a traveling state of a preceding vehicle based on an external environment information and the traffic congestion information, and to predict a stop position related to the preceding vehicle based on the acquired traveling state, an action plan generation unit that generates an action plan of the own vehicle based on the stop position and the currently located lane, and an information presentation unit that presents information including the generated action plan through using an external display device provided at a rear portion of a vehicle interior of the own vehicle.

## Claims

### Claim 1

An autonomous driving vehicle information presentation device used for an autonomous driving vehicle that acquires external environment information including a preceding vehicle existing ahead in a traveling direction of an own vehicle and automatically performs at least one of speed control and steering control of the own vehicle based on the acquired external environment information, the autonomous driving vehicle information presentation device being configured to present information to a traffic participant existing around the own vehicle, the autonomous driving vehicle information presentation device comprising:
a traffic congestion information acquisition unit configured to acquire information on traffic congestion ahead in the traveling direction of the own vehicle;
a traveling lane identification unit configured to identify a lane where the own vehicle is currently located;
a travelling state acquiring unit configured to acquire a traveling state including deceleration, slow traveling, and stop of the preceding vehicle based on the external environment information and the traffic congestion information;
an action plan generation unit configured to generate an action plan of the own vehicle based on the travelling state of the preceding vehicle, which travels a lane in which the own vehicle is to turn right or left, as acquired by the traveling state acquiring unit in a case where the own vehicle is scheduled to turn right or left at an intersection from the currently located lane; and
an information presentation unit configured to present information including the generated action plan through using an external display device provided at a rear portion of a vehicle interior of the own vehicle at a position visible to an occupant of a following vehicle, wherein
the traffic congestion information acquisition unit, the traveling lane identification unit, the action plan generation unit, and the information presentation unit are each implemented via at least one processor.

### Claim 2 (depends on 1)

The autonomous driving vehicle information presentation device according to claim 1 further comprising:
a signal information acquisition unit configured to acquire signal information on a traffic light existing ahead in the traveling direction of the own vehicle, wherein
the action plan generation unit is further configured to generate the action plan further based on information corresponding to the currently located lane among the signal information, and
the signal information acquisition unit is implemented via at least one processor.
