1. An in-motion power supply control device used in a wireless power transmission system, in which power is wirelessly transmitted from a primary coil in a supply device to a secondary coil in a vehicle, the in-motion power supply control device comprising:
a processor configured to:
perform different types of control depending on whether or not the supply device includes a foreign object detection unit for detecting whether a foreign object exists on the primary coil; and
limit a continuous power supply time for a vehicle in motion to a predetermined value or less in a case where the supply device that transfers power to the vehicle in motion does not include the foreign object detection unit, the predetermined value being set to a time that would not cause overheating of the foreign object,
wherein the processor is further configured to set the predetermined value to a variable value according to transmission power to the vehicle.
