1. A collision possibility acquiring apparatus for use with a host vehicle, comprising:
- a controller that;
acquires at least one track of the host vehicle until the lapse of a predetermined moving time according to a host vehicle predicted behavior selected based on a predetermined behavior selection probability associated with the host vehicle predicted behavior;
acquires a plurality of tracks of an obstacle about the host vehicle until the lapse of the predetermined moving time, each of the plurality of tracks of the obstacle being determined according to an obstacle predicted behavior selected based on a predetermined behavior selection probability associated with the obstacle predicted behavior; and
determines a collision possibility between the host vehicle and the obstacle based on the track of the host vehicle and the plurality of tracks of the obstacle.

Abstract
An own vehicle risk acquiring ECU 1 acquires a predicted track of an own vehicle and calculates and acquires a plurality of tracks of the other vehicle about the own vehicle. According to the predicted track of the own vehicle and the plurality of tracks of the other vehicle, a collision probability of the own vehicle is calculated as a collision possibility.
