A method for detecting at least one object between primary and secondary coils of a vehicle's inductive-charging-device. A first ultrasonic signal (FUS) is emitted with a first ultrasonic-transmitter (UT) situated at the primary-coil. A FUS-sequence is received with a first ultrasonic-receiver (FUR) at the vehicle. The FUS-sequence includes at least one first direct-receive signal. Alternatively/in addition, the FUS sequence includes additional receive signals, each of which corresponds to an indirect transmission of the ultrasonic-signal from the at least one UT to the FUR. The first direct receive signal is ascertained within the FUS-sequence and/or additional receive signals are ascertained within the FUS-sequence. The first received ultrasonic-signal-sequence, which includes the ascertained direct-receive-signal and/or ascertained additional receive signals is compared to a first reference-ultrasonic-signal-sequence. At least one object is subsequently detected between the primary and secondary coils as a function of this comparison.
