1. A driving support system for a vehicle, comprising:
- a vehicle which is provided with an image capturing portion that obtains image information on an area ahead of the vehicle; and
a moving object which can communicate with the vehicle through mobile communication,wherein the vehicle two-dimensionally determines a possibility that an estimated running vector of the moving object will intersect with an estimated running vector of the vehicle based on the information obtained through mobile communication; and
the vehicle corrects the two-dimensionally determined possibility when a road that overpasses or underpasses a road on which the vehicle is running is recognized ahead of the vehicle by the image capturing portion, and also it is determined that there is no road which two-dimensionally intersects with the road on which the vehicle is running.

Abstract
In a driving support system for a vehicle for determining the possibility that an estimated running vector of a moving object will intersect with an estimated running vector of a host vehicle using mobile communication, the possibility is three-dimensionally determined based on information obtained through mobile communication and image information on an area ahead of the host vehicle, which is obtained by image capturing means mounted on the vehicle.
