PROBLEM TO BE SOLVED: To accurately identify a travel lane for moving objects.SOLUTION: An identifying device acquires positional information on a moving object, detects objects present on a boundary between a driveway and any non-driveway space around the moving object, and calculates a distance to each of the objects. "Non-driveway space" refers to a sidewalk, median, building or fence adjoining a driveway for instance, and "objects present on a boundary between a driveway and any non-driveway space" include curbstones for example. And the identifying device identifies, on the basis of the distance to each of the objects and road information on that road, a travel lane for the moving object to travel on. Further, the identifying device figures out the reliability level of distances to the objects, and identifies a travel lane only when the reliability level is high enough.SELECTED DRAWING: Figure 3
【課題】精度よく移動体の走行レーンを判定する。【解決手段】判定装置は、移動体の位置情報を取得するとともに、移動体の周辺における車道と車道以外との境界に存在する物体を検出し、その物体までの距離を算出する。「車道以外」とは、例えば車道に隣接する歩道、中央分離帯、建物、塀などであり、「車道と車道以外との境界に存在する物体」は例えば縁石などである。そして、判定装置は、その物体までの距離と、その道路の道路情報とに基づいて、移動体が走行する走行レーンを判定する。さらに、判定装置は、物体までの距離の信頼度を求め、信頼度が高い場合のみ走行レーンの判定を行う。【選択図】図3
