Method for controlling the inductive charging of a user device and associated charging device for motor vehicle

Controlling inductive charging of a portable item of user equipment by a charging device. The charging device including a reception surface receiving the item of user equipment, emitter coils and a magnetic field guide to direct a magnetic field in a plane parallel to the reception surface. The charging device equipped with at least two magnetic antennas, each to emit a magnetic field and each designed to partially receive the magnetic field emitted by the other antenna. The method includes the following steps: Simultaneous emission by the two antennas, having a first phase shift at input with respect to one another; Measurement of at least one parameter at the output of the antennas; Storage of the measured parameter; Comparison between the at least one parameter thus measured and a predetermined value; Repetition of the preceding steps for other phase shift values; Controlling of the charging based on the comparison results.
