PROBLEM TO BE SOLVED: To output warning information by precisely determining a hazardous condition. SOLUTION: A one's own vehicle state recognition part 46 recognizes the traveling state and location of a one's own vehicle, and an object state recognition part 44 recognizes the moving state and location of an object around the one's own vehicle. A hazardous factor estimation part 48 estimates a hazardous factor with respect to the object based on the recognized traveling state of the one's own vehicle, the recognized moving state of the object and the collision risk of the collision between the one's own vehicle and the object by using the collision risk estimated by a collision risk estimation part 50, The collision risk estimation part 50 estimates the collision risk of the collision between the one's own vehicle and the object based on the recognized traveling state and location of the one's own vehicle, the recognized moving state and location of the object and the risk factor of the one's own vehicle with respect to the object by using the risk factor estimated by the risk factor estimation part 48. When the estimated collision risk is equal to or more than a threshold, warning information is output by an output part 16. COPYRIGHT: (C)2009,JPO&INPIT
