Abstract

An information provision system has a vehicle-mounted device, server, and mobile terminal, which send and receive information to and from one another. The vehicle-mounted device has an imaging unit that images a vicinity of a vehicle, and a first transmitting unit that sends position information, vehicle condition information, and captured image data, to the server. The server has a dangerous spot information creating unit that creates dangerous spot information having a danger level and associated with position information, based on the vehicle condition information and captured image data, and a second transmitting unit that sends the dangerous spot information to the mobile terminal. The mobile terminal has a third transmitting unit that sends position information to the server, a receiving unit that receives the dangerous point information corresponding to the position information of the mobile terminal, and an output unit that outputs a warning based on the dangerous spot information.

First claim

What is claimed is:

1. A server that receives information from a vehicle-mounted device on a vehicle, the server comprising:
a processor configured to:
receive position information, vehicle condition information of the vehicle, captured image data, and imaging time of the captured image data from the vehicle-mounted device on the vehicle;
create dangerous spot information based on the vehicle condition information of the vehicle and the captured image data, the dangerous spot information being a danger level, associated with the position information, and the imaging time of the captured image data; and
send the dangerous spot information to a mobile terminal,

wherein the processor is further configured to receive a current time from the mobile terminal, and
wherein the processor is further configured to send the dangerous spot information corresponding to the current time.

2. The server that receives information from a vehicle-mounted device according to claim 1 , wherein the processor is further configured to send the dangerous spot information having a predetermined danger level.

3. The server that receives information from a vehicle-mounted device according to claim 1 , wherein the mobile terminal includes a transmitter that sends position information of the mobile terminal to the processor,
wherein the mobile terminal includes a receiver for receiving the dangerous spot information corresponding to the position information of the mobile terminal, and
wherein the mobile terminal includes an output unit that Outputs a warning based on the dangerous spot information.

4. The server that receives information from a vehicle-mounted device according to claim 3 , wherein the mobile terminal includes an output unit that changes an output mode of the dangerous spot information according to an operation mode of the mobile terminal.

5. A method of receiving information from a vehicle-mounted device on a vehicle, the method comprising:
receiving position information, vehicle condition information of the vehicle, captured image data, and imaging time of the captured image data from the vehicle-mounted device on the vehicle;
creating dangerous spot information based on the vehicle condition information of the vehicle and the captured image data, the dangerous spot information being a danger level, associated with the position information, and the imaging time of the captured image data;
receiving a current time from a mobile terminal; and
sending the dangerous spot information to the mobile terminal corresponding to the current time.

6. The method of receiving information from a vehicle-mounted device according to claim 5 , wherein the dangerous spot information is sent having a predetermined danger level.

7. The method of receiving information from a vehicle-mounted device according to claim 5 , wherein the mobile terminal includes a transmitter that sends position information of the mobile terminal,
wherein the mobile terminal includes a receiver for receiving the dangerous spot information corresponding to the position information of the mobile terminal, and
wherein the mobile terminal includes an output unit that outputs a warning based on the dangerous spot information.

8. The method of receiving information from a vehicle-mounted device according to claim 7 , wherein the mobile terminal includes an output unit that changes an output mode of the dangerous spot information according to an operation mode of the mobile terminal.

9. A vehicle-mounted device on a vehicle, comprising:
a processor configured to:
send position information, vehicle condition information of the vehicle, captured image data, and imaging time of the captured image data to a server,
wherein the server is configured to create dangerous spot information based on the vehicle condition information of the vehicle and the captured image data, the dangerous spot information being a danger level, associated with the position information, and the imaging time of the captured image data, and
wherein the server is configured to receive a current time from a mobile terminal, and the server is configured to send the dangerous spot information to the mobile terminal corresponding to the current time.

10. The vehicle-mounted device according to claim 9 , wherein the image data is captured by an imaging unit that captures an image of a vicinity of a vehicle.

11. The vehicle-mounted device according to claim 9 , wherein the server is further configured to send the dangerous spot information having a predetermined danger level.

12. The vehicle-mounted device according to claim 10 , wherein the mobile terminal includes a transmitter that sends position information of the mobile terminal to the server,
wherein the mobile terminal includes a receiver fix receiving the dangerous spot information corresponding to the position information of the mobile terminal, and
wherein the mobile terminal includes an output unit that outputs a warning based on the dangerous spot information.

13. The vehicle-mounted device according to claim 12 , wherein the mobile terminal includes an output unit that changes an output mode of the dangerous spot information according to an operation mode of the mobile terminal.
