The invention relates to an inductive power transfer system for transferring electric energy to a vehicle (81), wherein the system comprises - a wayside electric conductor arrangement (1) for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle (81), - a vehicle side receiving device (2) for receiving the alternating electromagnetic field and for producing electric energy by magnetic induction, wherein - the wayside electric conductor arrangement (1) is combined with an array (14) of a plurality of sensor coils (4), the sensor coils (4) being placed side by side to form the array (14), - the array (14) extends in directions transverse to a field direction of the electromagnetic field, which field direction extends from the wayside electric conductor arrangement (1) to the vehicle side receiving device (2) during transfer of the energy to the vehicle, - a detector arrangement (12) is connected to the plurality of the sensor coils (4), the detector arrangement (12) being adapted to detect an effect of any magnetic and/or electrically conducting body (3, 6), that is possibly located in the field direction, on at least one electrical property of at least one of the sensor coils (4), - at least one marker body (6), which is a magnetic and/or electrically conducting body, is combined with the vehicle side receiving device (2), - a position determining device (15) is connected to the detector arrangement (12) and is adapted to determine a position of the vehicle side receiving device (2) from a detection result of the detector arrangement (12), the detection result indicating the sensor coil (4) / sensor coils (4) which is/are nearest to the marker body (6). The invention also relates to a method of operating and of manufacturing an inductive power transfer system. |
