Contactless power feeding system, control program for contactless power feeding system, vehicle, and contactless power feeding power receiving device

A vehicle capable of receiving power from a contactless power feeding system that contactlessly supplies power from a power supply segment provided on a traveling path to the vehicle,

• the vehicle comprising:
• a power reception characteristic acquisition unit that measures a power reception characteristic of the vehicle, the vehicle that causes an abnormality detection means to match a measurement period of a power transmission characteristic of the power supply segment measured by a power transmission characteristic acquisition unit provided on a side of the power supply segment with a measurement period of the power reception characteristic of the vehicle measured by the power reception characteristic acquisition unit, calculate efficiency of the power supply segment using the power transmission characteristic of the power supply segment and the power reception characteristic of the vehicle, the measurement periods of which are matched within 50 μs or less, and determine abnormality of the power supply segment on a basis of the calculated efficiency,
• wherein the vehicle causes the power reception characteristic acquisition unit to adjust a conversion gain based on the determined abnormality.
