Method and device for determining the absolute position of a vehicle

1. A method for determining an absolute position of a vehicle for close-range positioning of same when the vehicle is being parked, comprising:

providing a first transmitter as part of infrastructure;

providing a second transmitter as part of the infrastructure;

providing a reception device as part of the vehicle;

generating a positioning magnetic field by exciting the first transmitter;

generating a positioning signal by exciting the second transmitter;

detecting the positioning signal and the positioning magnetic field using the reception device;

using the positioning magnetic field and the positioning signal as a basis for ascertaining the absolute position of the vehicle; and

wherein the first transmitter and the second transmitter are both located as part of the infrastructure for charging one vehicle.

2. The method of claim 1 , further comprising generating a positioning magnetic field using the second transmitter.

3. The method of claim 2 , further comprising standardizing position of the second transmitter in relation to the first transmitter.

4. The method of claim 2 , further comprising determining position of the second transmitter in relation to the first transmitter.

5. The method of claim 4 , further comprising transmitting the position of the second transmitter via a different channel.

6. The method of claim 5 , further comprising providing the channel to be a wireless local area network.

7. The method of claim 1 , further comprising exciting the first transmitter and the second transmitter sequentially.

8. The method of claim 1 , further comprising:

providing at least one identifier;

distinguishing the first transmitter and the second transmitter from one another by virtue of the identifier being modulated onto the positioning signal.

9. The method of claim 1 , further comprising using different transmission frequencies for the first transmitter and the second transmitter.

10. The method of claim 1 , further comprising:

providing the vehicle to be an electrically operated vehicle;

determining the absolute position of the electrically operated vehicle for the close-range positioning of the electrically operated vehicle for inductive charging.

11. The method of claim 10 , further comprising providing the first transmitter to be a unit for inductively charging the vehicle.

12. The method as claimed in claim 11 , further comprising providing the unit employed for inductively charging to be a ground coil.

13. The method of claim 12 , further comprising:

providing a central charging station;

providing a plurality of ground coils located adjacent to one another;

operating the ground coils using the central charging station.

14. The method as claimed in claim 13 , further using one of the plurality of ground coils as the second transmitter.

15. The method of claim 1 , further comprising:

providing an optical system;

using the optical system as the second transmitter.

16. A device for determining an absolute position of a vehicle for close-range positioning of same when the vehicle is being parked, comprising:

a first transmitter being part of infrastructure, the first transmitter operable for generating a positioning magnetic field;

a second transmitter being part of the infrastructure, the second transmitter operable for generating a positioning signal;

a reception device as part of one of the infrastructure or the vehicle, the reception device operable for detecting the positioning signal and the positioning magnetic field;

wherein the positioning magnetic field and the positioning signal are used as a basis for ascertaining the absolute position of the vehicle; and

wherein the first transmitter and the second transmitter are both located as part of the infrastructure for charging one vehicle.
