Abstract
An apparatus and method for identifying foreign objects in an inductive charging system having a charging unit and a vehicle for inductive charging, in which the charging unit includes a primary coil and the vehicle has a secondary coil in order to transmit electrical power from the primary coil to the secondary coil during a charging operation. The vehicle includes a camera system, and a camera control unit. The camera system captures at least one image of the charging unit when the vehicle approaches the charging unit, at the beginning of a charging operation and/or during a charging operation. The camera control unit digitally processes the at least one captured image in order to detect a foreign body located on the charging unit.
