Abstract
A method and a corresponding device are provided for positioning a vehicle above a primary coil for inductive charging of a rechargeable battery in the vehicle. A control device for a vehicle is described. The vehicle has a secondary coil for receiving electrical energy from a primary coil outside the vehicle. The vehicle further has at least one camera, which is designed to detect an environment of the vehicle. The control unit is designed to receive image data from the at least one camera of the vehicle and to access reference data. The reference data includes information on at least one predefined reference object in the detected environment of the vehicle and on a position of the at least one predefined reference object relative to the primary coil. The control unit detects the at least one predefined reference object in the received image data on the basis of the reference data. In addition, the control unit determines a position of the secondary coil relative to the primary coil on the basis of the detected at least one reference object.
