1. A method for controlling a wireless charging device, comprising:

  • receiving information sensed by at least one of a yaw rate sensor, a gyro sensor, and a tire pressure sensor of a vehicle;

    calculating a longitudinal/transversal gradient of the vehicle according to the received information;

    adjusting a height or a gradient of a receiving pad equipped in the vehicle or adjusting a height, a gradient, a power transmitted to the receiving pad, or a frequency of a transmitting pad corresponding to the receiving pad, based on the calculated longitudinal/transversal gradient;

    transmitting power and frequency information, including a required power and frequency of the receiving pad, to the transmitting pad;

    calculating power transmission efficiency based on the power and frequency information and power transmitted to the receiving pad; and

    re-adjusting the height of the receiving pad when the calculated power transmission efficiency is equal to or less than a present tolerance.
