First Claim
1. A method of detecting a correct position and/or orientation of a secondary winding structure of a secondary unit relative to a primary winding structure of a primary unit of a system for inductive power transfer to a vehicle, the method comprising:
- providing a primary unit of a system for inductive power transfer;
providing a wayside control unit comprising at least one receiving means;
providing a vehicle comprising a secondary unit of the system for inductive power transfer, at least a first transmitter and a second transmitter;
generating, by the primary unit, an alternating electromagnetic field, wherein the wayside control unit controls the generation of the alternating electromagnetic field by the primary unit;
receiving, by the secondary unit, the alternating electromagnetic field;
transmitting, by the at least a first transmitter, a first signal;
transmitting, by the second transmitter, a second signal;
receiving, by the at least one receiving means of the wayside control unit, the first and the second signal;
detecting, depending on the first and second signal, the correct position and/or orientation of the secondary winding structure of the secondary unit relative to the primary winding structure of the primary unit;
determining, depending on the carrier signal level of the first and second signals, a correct position and/or orientation of the secondary winding structure of the secondary unit relative to the primary winding structure of the primary unit; and
determining a signal level of the first and second signals.

Abstract
A method of detecting a correct position and/or orientation of a secondary winding structure of a secondary unit relative to a primary winding structure of a primary unit of a system for inductive power transfer to a vehicle, wherein the vehicle includes the secondary unit for receiving an alternating electromagnetic field which is generated by the primary unit, wherein the vehicle includes at least a first transmitter for transmitting a first signal and a second transmitter for transmitting a second signal, wherein a wayside control unit includes at least one receiving means for receiving the first and the second signal, and wherein the correct position and/or orientation of the secondary winding structure of the secondary unit relative to the primary winding structure of the primary unit is detected depending on the first and the second signal.
