<p>The system (11) has an electric conductor (3) i.e. ground cable, arranged outside a controllable vehicle (1). A power input (2) is provided for the conductor. A reception unit (12) is arranged at the vehicle for electromagnetic field of conductor current. A coding device (7) produces a signal code in the current. A code recognition device (10) for the code is arranged at the vehicle and connected with the reception unit. An evaluation device (13) determines a local relationship of the sensor relative to the conductor from a current and/or voltage characteristic received from the conductor.</p> |
