Abstract
A wireless power transfer (WPT) control method using an object detection sensor, performed at a WPT apparatus, may include detecting whether or not an object exists between a transmission pad and a reception pad mounted on an electric vehicle (EV) using an object detection sensor; in response to detecting that an object does not exist between the transmission pad and the reception pad, controlling the transmission pad to perform WPT to the reception pad; and in response to detecting that an object exists between the transmission pad and the reception pad, generating ultrasonic waves using an ultrasonic wave generator.
