To provide a travel position determination device for determining a travel lane with high accuracy on the basis of GNSS position information.SOLUTION: In a travel position determination device, lane estimation means 2 estimates and outputs a travel lane position on the basis of a given time series of GNSS vehicle positions. Lane change estimation means 4 estimates and outputs the presence/absence of lane change on the basis of a given time series of speeds and lateral accelerations. Determination means 6 determines a travel lane position on the basis of the travel lane position estimated by the lane estimation means 2 and the presence/absence of lane change estimated by the lane change estimation means 4.EFFECT: A travel lane can be estimated with high accuracy even in the case of being based on data having low accuracy such as GNSS position data by determining a travel lane position on the basis of a lane estimation result based on GNSS position data having low accuracy and an estimation result of the presence/absence of lane change.SELECTED DRAWING: Figure 1

    【課題】GNSS位置情報に基づいて精度よく走行車線を判定する走行位置決定装置を提供する。【解決手段】走行位置決定装置において、車線推定手段2は、与えられた時系列のGNSS車両位置に基づいて、走行車線位置を推定し出力する。車線変更推定手段4は、与えられた時系列の速度、横方向加速度に基づいて、車線変更の有無を推定し出力する。確定手段6は、車線推定手段2によって推定された走行車線位置と、車線変更推定手段4によって推定された車線変更の有無とに基づいて、走行車線位置を確定する。【効果】精度の低いGNSS位置データに基づく車線推定結果と、車線変更の有無の推定結果とに基づいて、走行車線位置を確定させることで、GNSS位置データのような精度の低いデータに基づく場合であっても、精度良く走行車線の推定を行うことができる。【選択図】図1
