Patent ID: 11390323

Abstract:
A relative position of a power receiving unit to a power transmitting unit, represented by alignment assistance information, is corrected through a distance corresponding to a display delay time Δt1 and a vehicle response delay time Δt2. The relative position of one unit to the other at time t=t0−(Δt2+Δt1) is corrected to the relative position taken when it is assumed that a vehicle moves through a correction distance ΔP=ΔP1+ΔP2. Although a position of the power receiving unit is actually out of a chargeable area at each of the time t=t0−(Δt2+Δt1) and at time t=t0−Δt2, the alignment assistance information representing that the position of the power receiving unit is within the chargeable area is displayed on an image display device at the time t=t0−Δt2.
