Abstract

A notification device includes a calculation unit calculating, based on a speed of a vehicle, a vehicle stoppage distance by which the vehicle travels until the vehicle enters a stopped state while performing autonomous driving, a notification unit performing notification about information with respect to an outside of the vehicle, and a notification controller causing the notification unit not to perform notification about information indicating that the vehicle is in the middle of deceleration until the vehicle passes by a first soon-to-cross pedestrian and to cause the notification unit to perform notification about the information after the vehicle passes by the first soon-to-cross pedestrian when a distance between the vehicle and the first soon-to-cross pedestrian is smaller than the vehicle stoppage distance and a distance between the vehicle and a second soon-to-cross pedestrian is equal to or greater than the vehicle stoppage distance.

First claim

What is claimed is:

1. A notification device for notifying a moving object in vicinity of a vehicle of information, the device comprising:
an electronic control unit configured to:
recognize, based on a result of detection performed by an external sensor, positions of a first moving object and a second moving object, the second moving object positioned ahead of the first moving object in a proceeding direction of the vehicle; and
a notification unit including a display or a speaker provided in the vehicle and configured to perform notification about the information with respect to an outside of the vehicle,
wherein the electronic control unit is configured to control the notification unit, and
wherein the electronic control unit is configured to cause the notification unit to start to perform notification about information indicating that the vehicle is in the middle of deceleration after the vehicle passes by the first moving object when it is determined that the vehicle stops before reaching the second moving object after passing through the first moving object.

2. The notification device according to claim 1 , wherein the electronic control unit is configured to cause the notification unit not to perform notification about information until the vehicle passes by the first moving object.

3. The notification device according to claim 1 , wherein the electronic control unit is configured to cause the notification unit to perform notification about information indicating passage of the vehicle until the vehicle passes by the first moving object.
