VEHICLE POWER SUPPLY SYSTEM

To supply power from a power supply segment to a vehicle at an appropriate timing according to acceleration and deceleration of the vehicle.SOLUTION: A power supply device 100 of a vehicle power supply system 10 that supplies power to a vehicle 200 from the power supply device laid in a power supply lane LF of a vehicle travel path RS includes a plurality of power supply segments SEGs laid at a predetermined interval along the power supply lane, and a control device 140 that controls the plurality of power supply segments. The control device estimates a timing at which the vehicle arrives at the next power supply segment where power is supplied next to the current power supply segment where power is supplied, at least from a speed of the vehicle derived from a change in the position of the vehicle and starts the power supply by the next power supply segment at the estimated timing.SELECTED DRAWING: Figure 1 【課題】車両の加減速に応じた適切なタイミングで給電セグメントから車両へ給電を行なう。【解決手段】車両走行路ＲＳの給電レーンＬＦに敷設された給電装置１００から車両２００に対して給電を行なう車両給電システム１０の給電装置は、給電レーンに沿って、予め設定された間隔で敷設された複数の給電セグメントＳＥＧと、複数の給電セグメントを制御する制御装置１４０とを備える。制御装置は、給電が行なわれる現在給電セグメントの次に給電が行なわれる次期給電セグメントに前記車両が到達するタイミングを、少なくとも、車両の位置の変化から導出される車両の速度から推定し、推定したタイミングで次期給電セグメントによる給電を開始させる。【選択図】図１
