Abstract: A method for detecting a position of a robotic vehicle relative to a boundary conductor surrounding a defined area includes the steps: providing an electrical current and a pseudo-random boundary signal, generating a current signal using the electrical current and the pseudo-random boundary signal, feeding the current signal into the boundary conductor to produce an alternating electromagnetic field, detecting magnetic field changes which are attributed to the alternating electromagnetic field, and generating a reception signal from the magnetic field changes, evaluating the reception signal with the generation of at least one reconstructed boundary signal, providing a reference signal identical to the pseudo-random boundary signal, carrying out a pattern recognition to determine a correlation value between the reference signal and the reconstructed boundary signal, determining the position inside/outside the defined area based on the determined correlation value.
