Vehicle control device

A vehicle control device mounted on a vehicle including a power receiving device that receives power transmitted from a supply device on a ground side in a non-contact manner, and a battery charged by the power received by the power receiving device, the vehicle control device comprising a control unit that executes:

• setting a drive frequency determined based on voltage of the battery and required power on the vehicle side as a first drive frequency;
• transmitting the first drive frequency to the supply device using wide area wireless communication;
• receiving by the power receiving device the power transmitted in a non-contact manner while an inverter included in the supply device is controlled to the first drive frequency by the supply device that has received the first drive frequency, and charging the power to the battery;
• and
• performing feedback control to determine whether power transmission efficiency is higher after changing the drive frequency of the inverter to the first drive frequency than before changing the drive frequency, wherein
• the higher the voltage of the battery, the lower the first drive frequency, and
• the higher the required power, the higher the first drive frequency.
