Abstract
Official abstract text for this publication.
An out-of-vehicle notification device includes a traveling state detecting unit configured to detect a traveling state of the host vehicle, a first output unit configured to output a sound to an outside of the host vehicle, and a notification control unit configured to cause the first output unit to output a traveling notification sound indicating that the host vehicle is traveling when the host vehicle is traveling and to output a vehicle stoppage notification sound indicating that the host vehicle is stopped when the host vehicle is stopped. The traveling notification sound is a continuous sound continuously output. The vehicle stoppage notification sound is an intermittent sound intermittently output or a repetitive sound of which an intensity is repeatedly changed.
First claim
Opening claim text (preview).
What is claimed is: 1. An out-of-vehicle notification device which performs notification about a traveling state of a host vehicle with respect to a vicinity of the host vehicle by using a sound, the device comprising: a traveling state detecting unit configured to detect the traveling state of the host vehicle; a first output unit configured to output a sound to an outside of the host vehicle; and a notification control unit configured to cause the first output unit to output a traveling notification sound indicating that the host vehicle is traveling when the host vehicle is traveling and to output a vehicle stoppage notification sound indicating that the host vehicle is stopped when the host vehicle is stopped, based on the traveling state detected by the traveling state detecting unit, wherein the traveling notification sound is a continuous sound continuously output from the first output unit, and wherein the vehicle stoppage notification sound is an intermittent sound intermittently output from the first output unit or a repetitive sound of which an intensity is repeatedly changed. 2. The out-of-vehicle notification device according to claim 1 , further comprising: a notification target person detecting unit configured to detect a notification target person in a vicinity of the host vehicle; and a second output unit configured to output a sound to the outside of the host vehicle, wherein the notification control unit is configured to cause the second output unit to output a target person recognition sound indicating that the notification target person has been recognized to the notification target person when the notification target person is detected by the notification target person detecting unit, and wherein the target person recognition sound is a different kind of sound from the continuous sound. 3. The out-of-vehicle notification device according to claim 2 , wherein the second output unit is configured to be higher than the first output unit in directivity of an output sound, and wherein the notification control unit is configured to cause the second output unit to output the target person recognition sound toward the notification target person detected by the notification target person detecting unit when causing the second output unit to output the target person recognition sound. 4. The out-of-vehicle notification device according to claim 1 , wherein the host vehicle is an automatically driven vehicle which automatically travels based on a traveling plan, and wherein the traveling state detecting unit is configured to detect the traveling state based on the traveling plan.
