PROBLEM TO BE SOLVED: To suppress a reduction in accuracy of measuring an absolute position of a vehicle.SOLUTION: A vehicle position measurement system comprises: first measurement means (11, 12), mounted on a first vehicle (10), for measuring a first position that is an absolute position of the first vehicle; second measurement means (21, 22), mounted on a second vehicle (20), for measuring a second position that is an absolute position of the second vehicle; acquisition means (12, 13), mounted on the first vehicle, for acquiring a second position from the second vehicle on a condition that measurement accuracy of the first position does not satisfy prescribed accuracy, and acquiring a relative physical relationship between the first vehicle and the second vehicle; and specification means (12), mounted on the first vehicle, for specifying the absolute position of the first vehicle on the basis of the second position in place of the first position and the physical relationship on a condition that measurement accuracy of the second position satisfies the prescribed accuracy.SELECTED DRAWING: Figure 3
【課題】車両の絶対位置の検出精度の低下を抑制する。【解決手段】車両位置測定システムは、第1車両(10)に搭載され、第1車両の絶対位置である第1位置を測定する第1測定手段(11、12)と、第2車両(20)に搭載され、第2車両の絶対位置である第2位置を測定する第2測定手段(21、22)と、第1車両に搭載され、第1位置の測定精度が所定精度を満たしていないことを条件に、第2車両から第2位置を取得すると共に、第1車両及び第2車両間の相対的な位置関係を取得する取得手段(12、13)と、第1車両に搭載され、第2位置の測定精度が所定精度を満たしていることを条件に、第1位置に代えて、第2位置及び位置関係に基づいて第1車両の絶対位置を特定する特定手段(12)と、を備える。【選択図】図3
