Abstract
A vehicle control device is mounted on a vehicle that includes a power receiving device that receives power transmitted in a non-contact manner from a ground-side supply device and a battery that charges the power received by the power receiving device. The drive frequency determined based on the requested power of the side is set as the first drive frequency, and the first drive frequency is transmitted to the supply device using wide area wireless communication. When the inverter included in the supply device is controlled to the first drive frequency, the power receiving device receives the power transmitted in a contactless manner and charges the battery, and the power is transferred before and after changing the inverter drive frequency to the first drive frequency. Feedback control is performed to check whether the transmission efficiency is high.
