Abstract

A method for determining the absolute position of a vehicle for the close-range positioning of same when the vehicle is being parked is described. An inductive positioning method is performed, wherein a first transmitter in the infrastructure or in the vehicle is excited to generate a positioning magnetic field and a second transmitter in the infrastructure or in the vehicle is excited to generate a positioning signal. The positioning magnetic field and the positioning signal are received by a reception device in the vehicle or in the infrastructure and the received positioning magnetic field and positioning signal are taken as a basis for ascertaining the absolute position of the vehicle. This allows particularly exact parking of the vehicle, in particular of an electrically operated vehicle for inductive charging.
