Abstract

An information processing system is equipped with a ranging unit that measures a distance from a vehicle to an object existing around the vehicle, a sound collection unit that collects a sound around the vehicle, a sound pressure level detection unit that detects a sound pressure level representing an intensity of the sound, a contact detection unit that detects a contact of the vehicle with the object when the sound pressure level that is detected when the distance is equal to zero becomes higher than a predetermined threshold, and a user specification unit that specifies a user of the vehicle of which the contact has been detected, based on user identification information for identifying the user of the vehicle, when the contact is detected.

First claim

What is claimed is:

1 . An information processing system comprising:
a ranging unit that measures a distance from a vehicle to an object existing around the vehicle; a sound collection unit that collects a sound around the vehicle; a sound pressure level detection unit that detects a sound pressure level representing an intensity of the sound; a contact detection unit that detects a contact of the vehicle with the object when the sound pressure level that is detected when the distance is equal to zero becomes higher than a predetermined threshold; and a user specification unit that specifies a user of the vehicle of which the contact has been detected, based on user identification information as information for identifying the user of the vehicle, when the contact is detected.

2 . The information processing system according to claim 1 , wherein
the user specification unit associates timing information indicating a timing of occurrence of the contact with the user specification information as the information for specifying the user of the vehicle of which the contact has been detected, and stores the timing information associated with the user specification information into the storage unit.

3 . The information processing system according to claim 1 , further comprising:
a contact sound specification unit that analyzes the sound collected by the sound collection unit and that specifies a contact sound of the vehicle with the object, wherein the contact detection unit detects the contact when the sound pressure level that is detected when the distance is equal to zero becomes higher than the predetermined threshold and the contact sound is specified.

4 . The information processing system according to claim 1 , comprising, instead of the sound pressure level detection unit:
an acceleration detection unit that detects an acceleration of the vehicle; and an acceleration determination unit that determines whether or not the acceleration has become larger than a predetermined threshold, wherein the contact detection unit detects the contact when the acceleration becomes larger than the predetermined threshold, instead of a case where the sound pressure level becomes higher than the predetermined threshold.

5 . The information processing system according to claim 1 , further comprising:
an acceleration detection unit that detects an acceleration of the vehicle; and an acceleration determination unit that determines whether or not the acceleration has become larger than a predetermined threshold, wherein the contact detection unit detects the contact when the sound pressure level that is detected when the distance is equal to zero becomes higher than the predetermined threshold and the acceleration becomes larger than the predetermined threshold.

6 . The information processing system according to claim 1 , further comprising:
an imaging unit that images an outer peripheral portion of the vehicle, wherein the user specification unit associates imaging data imaged by the imaging unit with the user specification information as the information for specifying the user of the vehicle of which the contact has been detected, and stores the imaging data associated with the user specification information into the storage unit.

7 . The information processing system according to claim 1 , further comprising:
a server that stores the user specification information as the information for specifying the user of the vehicle of which the contact has been detected.

8 . The information processing system according to claim 1 , further comprising:
an in-vehicle machine that stores the user specification information as the information for specifying the user of the vehicle of which the contact has been detected.

9 . An information processing program for causing a computer to carry out:
a step of measuring a distance from a vehicle to an object existing around the vehicle; a step of collecting a sound around the vehicle; a step of detecting a sound pressure level representing an intensity of the sound; a step of detecting a contact of the vehicle with the object when the sound pressure level that is detected when the distance is equal to zero becomes higher than a predetermined threshold; and a step of specifying a user of the vehicle of which the contact has been detected, based on user identification information as information for identifying the user of the vehicle, when the contact is detected.

10 . An information processing program for causing a computer to carry out:
a step of measuring a distance from a vehicle to an object existing around the vehicle; a step of detecting an acceleration of the vehicle; a step of detecting a contact of the vehicle with the object when the acceleration that is detected when the distance is equal to zero becomes higher than a predetermined threshold; and a step of specifying a user of the vehicle of which the contact has been detected, based on user identification information as information for identifying the user of the vehicle, when the contact is detected.
