PROBLEM TO BE SOLVED: To calculate the position of a vehicle by use of a landmark which is unlikely to be hidden by another vehicle when the vehicle turns right or left at an intersection.SOLUTION: A position detection apparatus 40 estimates whether a vehicle 1 performs a direction change which is at least one of a right turn and a left turn, at an intersection 70. When the vehicle 1 is estimated to perform a direction change, the position detection apparatus 40 selects only a combination of landmarks located on the right or left side of the intersection 70 to which the vehicle 1 is to turn, as seen from a position of the vehicle 1 before turning.
【課題】交差点で車両が右左折する際に、他の車両によって車両からの見通しが遮られにくいランドマークを使用して車両の位置を算出する。【解決手段】位置検出装置40は、交差点70で車両1が右折及び左折の少なくともひとつである方向変更を行うか否かを推定する。位置検出装置40は、車両1が方向変更を行うと推定された場合に、方向変更前の車両1の位置からみて交差点70の右側及び左側のうち車両1の方向変更側にあるランドマークの組合せのみを選択する。【選択図】図3
