To provide a vehicle position determining device with which it is possible to determine the position or travel direction of the own vehicle with high accuracy even when traveling a section, such a tunnel, where positioning signals from satellites cannot be received stably.SOLUTION: Provided is a vehicle position determining device 100 comprising first position detection means 107 for detecting a vehicle position on the basis of a signal from a satellite, second position detection means 108 for detecting a vehicle position on the basis of the result of detection of the vehicle's travel parameter including at least the vehicle bearing, and matching means 109 for causing the vehicle position to be matched to at least a map based on a link. When traveling a section where the detection accuracy of the first position detection means 107 decreases, the second position detection means 108 estimates the travel direction of the vehicle from the direction of the link of the section and the result of detection of the vehicle bearing.SELECTED DRAWING: Figure 1
【課題】トンネルなどの衛星からの測位信号を安定して受信できない区間を走行する場合であっても、自車両の位置や進行方向が精度良く判定できる車両位置判定装置を提供する。【解決手段】衛星からの信号に基づいて車両位置を検出する第一位置検出手段107と、少なくとも車両方位を含む車両の走行パラメータの検出結果に基づいて車両位置を検出する第二位置検出手段108と、前記車両位置を少なくともリンクに基づく地図にマッチングさせるマッチング手段109と、を有する車両位置判定装置100において、第二位置検出手段108は、前記第一位置検出手段107の検出精度が低下する区間を走行する場合に、該区間の前記リンクの方向と前記車両方位の検出結果とから該車両の進行方向を推定する。【選択図】図1
