To achieve efficient power transmission from a power transmission coil provided on a road to a power reception coil provided in a vehicle.SOLUTION: A power transmission control device includes: a power transmission unit 63 that transmits electric power from a power transmission coil 45 provided on a road to a power reception coil 52 provided in a vehicle when the vehicle 3 travels on the road; a position deviation estimation unit 64 for calculating an estimation value of a position deviation amount between the power transmission coil and the power reception coil based on data indicating a relative position relation between the power transmission coil and the power reception coil; and a vehicle speed acquisition unit 65 for acquiring speed of the vehicle. The power transmission unit starts power transmission from the power transmission coil to the power reception coil when the estimation value becomes equal to or less than a threshold, and sets the threshold to be smaller when speed of the vehicle is low than when the speed of the vehicle is high.SELECTED DRAWING: Figure 7
【課題】道路に設けられた送電コイルから車両に設けられた受電コイルへの効率的な送電を実現する。【解決手段】送電制御装置は、車両3が道路を走行しているときに、道路に設けられた送電コイル45から車両に設けられた受電コイル52へ電力を送電する送電部63と、送電コイルと受電コイルとの間の相対的な位置関係を示すデータに基づいて、送電コイルと受電コイルとの位置ずれ量の推定値を算出する位置ずれ推定部64と、車両の速度を取得する車速取得部65とを備える。送電部は、推定値が閾値以下になったときに送電コイルから受電コイルへの送電を開始し、車両の速度が低いときには、車両の速度が高いときと比べて、閾値を小さくする。【選択図】図7
