Abstract

An information providing system includes a detection information acquisition unit configured to acquire a detection result of a vehicle sensor, an occupant information database configured to hold occupant information generated based on a previous detection result of the vehicle sensor, and an output controller configured to, when information relating to an occupant acquired from the detection result of the vehicle sensor conforms to the occupant information held in the occupant information database, output provided information according to the occupant information to the occupant.

Claims

1. An information providing system comprising:

a detection information acquisition unit configured to acquire a detection result of a vehicle sensor;

an occupant information database configured to hold occupant information generated based on a previous detection result of the vehicle sensor; and

an output controller configured to, when information relating to an occupant acquired from the detection result of the vehicle sensor conforms to the occupant information held in the occupant information database, output provided information according to the occupant information to the occupant.

2. The information providing system according to claim 1, wherein:

the detection information acquisition unit is configured to acquire an utterance of the occupant from a microphone included in the vehicle sensor; and

the occupant information database is configured to hold occupant information generated based on the utterance of the occupant.

3. The information providing system according to claim 2, wherein the occupant information database is configured to classify and hold an uttered word of the occupant as affirmative or negative.

4. The information providing system according to claim 1, wherein the occupant information database is configured to hold the occupant information for each occupant.

5. The information providing system according to claim 4, wherein:

the occupant information database is configured to hold boarding information of each occupant as the occupant information; and

the output controller is configured to, when a current occupant coincides with a previous occupant, output information acquired at a time of coincident previous boarding as the provided information.

6. The information providing system according to claim 1, wherein:

the occupant information database is configured to hold event information at a time of previous boarding in association with the occupant; and

the output controller is configured to, when a degree of coincidence of a current situation to be acquired from the detection result of the vehicle sensor and previous event information is equal to or greater than a predetermined value, output the event information at the time of previous boarding.

7. An information providing method comprising:

acquiring a detection result of a vehicle sensor mounted in a vehicle;

holding occupant information generated based on the detection result of the vehicle sensor; and

when information relating to an occupant acquired from the detection result of the vehicle sensor conforms to the held occupant information, outputting provided information according to the occupant information to the occupant.

8. An information providing system comprising:

a server device configured to hold occupant information generated based on a previous detection result of a vehicle sensor; and

an in-vehicle device configured to acquire a detection result of the vehicle sensor, and when information relating to an occupant acquired from the detection result of the vehicle sensor conforms to the occupant information held in the server device, output provided information according to the occupant information to the occupant.

9. The information providing system according to claim 8, wherein:

the in-vehicle device is configured to acquire an utterance of the occupant from a microphone included in the vehicle sensor; and

the server device is configured to hold occupant information generated based on the utterance of the occupant.

10. The information providing system according to claim 9, wherein the server device is configured to classify and hold an uttered word of the occupant as affirmative or negative.

11. The information providing system according to claim 8, wherein the server device is configured to hold the occupant information for each occupant.

12. The information providing system according to claim 11, wherein:

the server device is configured to hold boarding information of each occupant as the occupant information; and

the in-vehicle device is configured to, when a current occupant coincides with a previous occupant, output information acquired at a time of coincident previous boarding as the provided information.

13. The information providing system according to claim 8, wherein:

the server device is configured to hold event information at a time of previous boarding in association with the occupant; and

the in-vehicle device is configured to, when a degree of coincidence of a current situation to be acquired from the detection result of the vehicle sensor and previous event information is equal to or greater than a predetermined value, output the event information at the time of previous boarding.
