On-vehicle road configuration identifying device
First Claim
1. An on-vehicle road configuration identifying device mounted on a user'"'"'s vehicle, which identifies the road configuration near said user'"'"'s vehicle, said device comprising:
- a traveling path detecting section that is configured to detect the traveling path of at least one subject vehicle, where said at least one subject vehicle includes at least one vehicle near the user'"'"'s vehicle;
a certainty level calculating section that is configured to calculate for each subject vehicle a level of certainty that the subject vehicle is traveling along a road; and
a road configuration predicting section that is configured to predict as a road configuration near the user'"'"'s vehicle the road configuration for at least one of said subject vehicles having a certainty level calculated by said certainty level calculating section that is higher than a certainty level calculated by said certainty level calculating section for at least one other of said subject vehicles.

Abstract
A road configuration identifying device properly identifies the road configuration around a user'"'"'s vehicle. A reliability level indicating whether the traveling paths of other vehicles in an area behind the user'"'"'s vehicle which are detected by a radar positioning system, which are obtained by tracking other vehicles using an other vehicle tracking section, and the traveling path of the user'"'"'s vehicle are traveling paths along the same road configuration is calculated by using the velocity v, acceleration dv, angular velocity dθ, and the operation state of a direction indicator or the like of each vehicle. Then, the road configuration indicated by traveling paths having a high reliability level is predicted as the road configuration in the area behind the user'"'"'s vehicle. A warning device evaluates the possibility of other vehicles colliding with the user'"'"'s vehicle based on the road configuration of the area behind the user'"'"'s vehicle predicted by the road configuration predicting section and the behavior of other vehicles tracked by the other vehicle tracking section, and warns of the possibility of collision if such another vehicle is present.

21. A road configuration identifying method for identifying the road configuration near a user'"'"'s vehicle, said method comprising:
-
detecting the traveling path of at least one subject vehicle, where said at least one subject vehicle includes at least one vehicle near the user'"'"'s vehicle; calculating a certainty level for each subject vehicle that the subject vehicle is traveling along a road based on the state of the subject vehicle; and predicting using a processor, as the road configuration near the user'"'"'s vehicle, a road configuration associated with at least one of said subject vehicles having a calculated certainty level that is higher than a certainty level calculated for at least one other of said subject vehicles. - View Dependent Claims (22, 23)
