To appropriately supply a vehicle with power even when the vehicle travels relatively fast to suppress generation of a leakage magnetic field.SOLUTION: A non-contact power supply system supplies a power incoming coil (101) mounted on a vehicle (10) that travels on a road with power in a non-contact fashion from a plurality of power transmission coils (201) installed on the road. The non-contact power supply system includes: first estimation means (1021, 2021, 51) for estimating a future position of the vehicle based on speed of the vehicle; and specification means (1022, 2022, 52) for specifying the power transmission coil that should be made a startup status among the plurality of power transmission coils based on the estimated future position.SELECTED DRAWING: Figure 1
【課題】車両が比較的速く走行している場合であっても、該車両に適切に電力を供給するとともに、漏洩磁界の発生を抑制する。【解決手段】非接触給電システムは、道路に配設された複数の送電コイル(201)から、道路上を走行する車両(10)に搭載された受電コイル(101)に非接触で電力を供給する。当該非接触給電システムは、車両の速度に基づいて、該車両の将来の位置を推定する第1推定手段(1021、2021、51)と、推定された将来の位置に基づいて、複数の送電コイルのうち、起動状態にすべき送電コイルを特定する特定手段(1022、2022、52)と、を備える。【選択図】図1
