1. A method for detecting foreign objects in an induction charging device, comprising:
- ascertaining in a first method step, using a control unit of the induction charging device, a resonance frequency at an oscillator component of the induction charging device;
determining in a second method step, using the control unit, an actual quality at the resonance frequency; and
comparing in a third method step, using the control unit, the determined actual quality at the resonance frequency to a setpoint quality which is a function of the resonance frequency.
