In-motion power supply system, and abnormality determination method for electrical characteristics in said system

An in-motion power supply system comprising:

• a plurality of power supply segments configured to supply power to a vehicle;
• a vehicle position detection unit configured to detect a position of the vehicle relative to each of the power supply segments;
• an electrical characteristic acquisition unit configured to acquire electrical characteristics in the power supply segment involved in power transfer when electric power is supplied to the vehicle from the plurality of power supply segments;
• and
• an abnormality determination unit configured to use the electrical characteristics to determine whether there is an abnormality in the power supply segment involved in power transfer,
• wherein the abnormality determination unit shares the electrical characteristics between a subject segment which is the power supply segment subjected to abnormality determination and at least one of a previous segment which is the power supply segment that was involved in power transfer previous to the subject segment and a subsequent segment which is the segment that will be involved in power transfer 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.
