Abstract: In an in-motion power supply system with a plurality of power supply segments to supply power to a vehicle, a vehicle position detection unit detects a position of the vehicle relative to each segment. An electrical characteristic acquisition unit acquires electrical characteristics in the segment involved in power transfer, and an abnormality determination unit uses the electrical characteristics to determine whether there is an abnormality in the segment involved in power transfer. The abnormality determination unit shares the electrical characteristics between a subject segment subjected to abnormality determination and at least one of a previous segment previous to the subject segment and a subsequent segment subsequent to the subject segment, and compares the electrical characteristics in the subject segment with at least either the electrical characteristics in the previous segment or the electrical characteristics in the subsequent segment to determine whether the electrical characteristics in the subject segment are abnormal.

Abstract: In a moving-object power supply system, a control unit selects, as a power transmission segment, one of segments included in at least one power transmission section. The control unit supplies, through a power supply circuit, power to the power transmission segment to thereby generate a magnetic field through a power transmission coil of the power transmission segment. The control unit determines, based on an ascertained first electrical characteristic of the power transmission segment and an ascertained second electrical characteristic of at least one power non-transmission segment, whether there is a malfunction in each of the power transmission segment and the at least one power non-transmission segment.
