To properly determine whether erroneous route transformation has been made in the event that a set route in a navigation map is transformed into an actual use route in a high-precision map.SOLUTION: An erroneous route transformation determination system determines whether erroneous route transformation has been made in the event that a set route in a navigation map for a navigation system of a vehicle is transformed into an actual use route in a high-precision map. Position information on an intersection on the set route and an advance angle at the intersection on the set route are extracted based on the navigation map and set route. Position information on an intersection on an actual use route and an advance angle at the intersection on the actual use route are extracted based on the high-precision map and actual use route. Whether erroneous route transformation has been made is determined based on an advance angle on the set route at a common intersection, which is an intersection common between the set route and actual use route, and an advance angle on the actual use route.SELECTED DRAWING: Figure 3
【課題】ナビ地図上の設定経路を高精度地図上の実用経路へ変換した場合の経路誤変換の有無を適切に判定する。【解決手段】車両のナビゲーションシステム用のナビ地図上の設定経路を高精度地図上の実用経路に変換した場合の経路誤変換の有無を判定する経路誤変換判定装置であって、ナビ地図と設定経路とに基づいて、設定経路上の交差点の位置情報と設定経路の交差点における進行角度とを抽出し、高精度地図と実用経路とに基づいて、実用経路上の交差点の位置情報と実用経路上の交差点における進行角度とを抽出し、設定経路と実用経路で共通する交差点である共通交差点における設定経路上の進行角度と実用経路上の進行角度とに基づいて経路誤変換の有無を判定する。【選択図】図3
