Abstract

A road information sharing method according to the present invention is a road information sharing method for sharing the road information via a terminal device, the road information sharing method including the steps of storing sensor information acquired from a vehicle moving in accompaniment with the terminal device, detecting the road information from the sensor information on the basis of detection rules for detecting the road information, notifying a user about the road information detected, and prompting the user to make a judgment of necessity/unnecessity of registration about the detected road information, and storing the detected road information, if the detected road information is judged to be registration-necessary by the user.

Claims

1. A road information sharing method in a road information sharing system for sharing road information, comprising:

storing sensor information acquired from a terminal device or a vehicle moving in accompaniment with said terminal device;

detecting said road information from said sensor information based on detection rules for detecting said road information;

estimating a driving state of said vehicle from said sensor information based on estimation rules for estimating said driving state of said vehicle moving in accompaniment with said terminal device;

judging whether or not said estimated driving state is a state in which it is allowable to prompt a user to make a judgment of necessity/unnecessity of registration of said detected road information based on said driving state;

notifying said user about said detected road information;

when said driving state is said state in which it is allowable to prompt said user, prompting said user to make said judgment of necessity/unnecessity of registration about said detected road information;

when said driving state is not said state in which it is allowable to prompt said user, waiting for said driving state to become said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration, and then prompting said user to make said judgment of necessity/unnecessity of registration; and

when said detected road information is judged to be registration necessary by said user, storing said detected road information or outputting said detected road information to an external device,

wherein said notification to said user is executed a plurality of times including a first time of notifying said user about said detected road information using a sound and a second time of notifying said user about said detected road information using a pop-up or image information for prompting said user to make said judgment of necessity/unnecessity of registration about said detected road information.

2. The road information sharing method according to claim 1, further comprising:

when driving state is not said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration, notifying said user that said user will be prompted to make said judgment of necessity/unnecessity of registration at a later time.

3. The road information sharing method according to claim 1, wherein whether or not said estimated driving state is said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration of said detected road information is judged based on said driving state, said stored sensor information and map information.

4. A road information sharing method in a road information sharing system for sharing road information, comprising the steps of:

storing sensor information acquired from a terminal device or a vehicle moving in accompaniment with said terminal device;

detecting said road information from said sensor information based on detection rules for detecting said road information;

estimating a driving state of said vehicle from said sensor information based on estimation rules for estimating said driving state of said vehicle moving in accompaniment with said terminal device;

judging whether or not said estimated driving state is a state in which it is allowable to prompt a user to make a judgment of necessity/unnecessity of registration of said detected road information based on said driving state;

notifying said user about said road information detected;

when said driving state is said state in which it is allowable to prompt said user, prompting said user to make said judgment of necessity/unnecessity of registration about said detected road information by displaying an image; and

when said detected road information is judged to be registration necessary by said user, storing said detected road information or outputting said detected road information to an external device,

wherein, when said driving state changes from said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration to said state in which it should not be performed to prompt said user to make said judgment of necessity/unnecessity of registration, said image is controlled so as not to be displayed.

5. The road information sharing method according to claim 4, further comprising:

when said driving state is not said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration, waiting for said driving state to become said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration, and then prompting said user to make said judgment of necessity/unnecessity of registration.

6. The road information sharing method according to claim 5, wherein said notification to said user is executed a plurality of times including a first time of notifying said user about said detected road information using a sound and a second time of notifying said user about said detected road information using a pop-up or image information for prompting said user to make said judgment of necessity/unnecessity of registration about said detected road information.

7. The road information sharing method according to claim 4, further comprising:

when said driving state is not said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration, notifying said user that said user will be prompted to make said judgment of necessity/unnecessity of registration at a later time.

8. The road information sharing method according to claim 4, wherein whether or not said estimated driving state is said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration of said detected road information is judged based on said driving state, said stored sensor information and map information.

9. A road information sharing method in a road information sharing system for sharing road information, comprising the steps of:

storing sensor information acquired from a terminal device or a vehicle moving in accompaniment with said terminal device;

detecting said road information from said sensor information based on detection rules for detecting said road information;

notifying a user about said road information detected, and prompting said user to make a judgment of necessity/unnecessity of registration about said detected road information; and

storing said detected road information, or outputting said detected road information to an external device, if said detected road information is judged to be registration necessary by said user,

wherein, when said road information is detected as plural pieces of road information, said user is notified about said detected plural pieces of road information in accordance with priority degrees being assigned based on respective detection points-in-time or respective distances between detection locations and a present position.

10. The road information sharing method according to claim 9, further comprising:

estimating a driving state of said vehicle from said sensor information based on estimation rules for estimating said driving state of said vehicle moving in accompaniment with said terminal device; and

judging whether or not said estimated driving state is a state in which it is allowable to prompt said user to make a judgment of necessity/unnecessity of registration of said detected road information based on said driving state.

11. The road information sharing method according to claim 10, further comprising:

when driving state is said state in which it is allowable to prompt said user to make said judgment of necessity/unnecessity of registration, prompting said user to make said judgment of necessity/unnecessity of registration about said detected road information; and
