The invention relates to a method and an arrangement for inductive positioning of a current collector (14; 24) on a vehicle relative to a stationary current conductor (13; 23; 33; 43; 53). The invention involves transmitting a signal having predetermined phase characteristics using a signal transmitter (37; 47; 57) arranged along the longitudinal direction of the current conductor (13; 23; 33; 43; 53); detecting the transmitted signal using a signal receiver on the vehicle, which signal receiver comprises at least one vertical antenna (30; 40; 50a, 50b); detecting the phase characteristics of the signal induced in the at least one vertical antenna (30; 40; 50a, 50b), indicating the relative location of the vertical antenna (30; 40; 50a, 50b) and the signal transmitter (37; 47; 57) in the transverse direction of the vehicle; and controlling the positioning means (25, 26) in dependence of the received signals.

A system for determining the position of a transport vehicle that can be moved over a floor, in particular a heavy-load transport vehicle, comprising an antenna which can be attached to a lower face of the transport vehicle and a transponder which can be introduced into the floor at a specific location and which can be charged by means of a transmission field that can be generated by the antenna during a transmission interval and can be evaluated during a subsequent evaluation interval. The system is designed such that the evaluation interval is discontinued and a new transmission interval is started if a signal of the transponder cannot be detected during a detection interval within the evaluation interval.
