To provide a technique for improving an accuracy of determining a risk of collision of another vehicle with an own vehicle.SOLUTION: A risk determination system is configured by comprising: a relative positional information acquisition unit that acquires a relative position of another vehicle existing in the vicinity of an own vehicle with respect to the own vehicle; a road information acquisition unit that acquires road information indicating a position and a shape of a road around a present position of the own vehicle; an other vehicle behavior estimation unit which acquires a shortest distance between the other vehicle and the road based on the relative position, the present position of the own vehicle, and the road information, and estimates that the other vehicle exists on the road when the shortest distance is equal to or less than a default value; and a risk determination unit that determines a collision risk of the other vehicle with the own vehicle based on the estimation result.SELECTED DRAWING: Figure 1

    【課題】自車両に対する他車両の衝突リスクの判定精度を向上させる技術の提供。【解決手段】自車両の周辺に存在する他車両の、前記自車両を基準とした相対位置を取得する相対位置情報取得部と、前記自車両の現在位置周辺の道路の位置および形状を示す道路情報を取得する道路情報取得部と、前記相対位置と前記自車両の現在位置と前記道路情報とに基づいて前記他車両と前記道路との最短距離を取得し、前記最短距離が既定値以下の場合に前記道路上に前記他車両が存在すると推定する他車両挙動推定部と、推定結果に基づいて、前記自車両に対する前記他車両の衝突リスクを判定するリスク判定部と、を備えるリスク判定システムを構成する。【選択図】図1
