To transfer electric power efficiently from a travel road to a mobile body and enable the mobile body to run stably even when there is a step or a gradient change on the travel road.SOLUTION: A mobile body 120 of a wireless electric power transmission system includes: a power reception electrode 123 that is provided opposite to a travel road R; a battery 124; an actuator 125 that lifts up and down the power reception electrode 123 to adjust a distance from the travel road R; a self-position estimation unit 127 that estimates a self position; and a control unit 130 that includes an environment map corresponding to a travel range of the mobile body 120. In the environment map, a region where traveling is possible with a power transmission electrode 111 provided in the travel road R and the power reception electrode 123 lifted down to get close to the travel road R is registered as a power reception-enabled region. When the self position exists inside the power reception-enabled region, the control unit 130 causes the power reception electrode 123 to get close to the travel road R so as to receive the electric power and causes the battery 124 to store the electric power.SELECTED DRAWING: Figure 2

    【課題】走行路から移動体へ電力を効率的に伝送しつつ、走行路上に段差や勾配の変化がある場合においても移動体を安定して走行させることを可能とする。【解決手段】無線電力伝送システムの移動体120は、走行路Rに対向して設けられた受電電極123と、バッテリ124と、受電電極123を昇降させて走行路Rからの距離を調整するアクチュエータ125と、自己位置を推定する自己位置推定部127と、を備え、移動体120の走行範囲に対応する環境地図を備える制御部130を更に備え、環境地図には、走行路Rに送電電極111が設けられ、かつ受電電極123を降ろして走行路Rに接近させた状態で走行可能な領域が、受電可能領域として登録され、制御部130は、自己位置が受電可能領域の内側に位置する場合に、受電電極123を走行路Rに接近させて電力を受電し、バッテリ124に電力を蓄える。【選択図】図2
