Abstract

The invention relates to a charging/discharging station (2) for charging or discharging an at least partly battery-operated vehicle (14) via an inductively coupled pair of coils. The charging/discharging station (2) comprises in particular a computer device (12), in which spatial coordinates of parking areas (4) are stored and which has means to navigate a vehicle (14) to the parking area (4) by means of communication units (8, 16) by using image data of the vehicle (14) recorded by means of a camera device (10) and by using physical coordinates of the parking areas (4). The invention further relates to a method for operating such a loading/discharging station (2).

First claim

The invention claimed is:

1. A charging/discharging station ( 2 ) for charging or discharging an at least partially battery-operated vehicle ( 14 ) via an inductively coupled pair of coils, the charging/discharging station ( 2 ) comprising
at least one parking space ( 4 ) with a primary coil ( 6 ), the primary coil ( 6 ) being able to form the inductively coupled pair of coils together with a secondary coil ( 18 ) of a vehicle ( 14 ) to be discharged and/or charged,
a first communication unit ( 8 ) which is set up to communicate with a second communication unit ( 16 ) of the vehicle ( 14 ),
at least one camera device ( 10 ) which is connected to a computer device ( 12 ) for processing recorded image data, the computer device ( 12 ) storing spatial coordinates of the at least one parking space ( 4 ), and the computer device ( 12 ) having means for navigating the vehicle ( 14 ) to the at least one parking space ( 4 ) on the basis of image data relating to the vehicle ( 14 ) which are recorded by the camera device ( 10 ) and the spatial coordinates of the at least one parking space ( 4 ) by means of the first and second communication units ( 8 , 16 ), wherein the camera device flies autonomously above the parking spaces.

2. The charging/discharging station ( 2 ) as claimed in claim 1 , characterized in that the camera device ( 10 ) is positioned with respect to the at least one parking space ( 4 ) in such a manner that a plan view of the at least one parking space ( 4 ) is possible.

3. The charging/discharging station ( 2 ) as claimed in claim 1 , characterized in that the camera device ( 10 ) is formed by stereo cameras.

4. The charging/discharging station ( 2 ) as claimed in claim 1 , characterized in that the charging/discharging station ( 2 ) has a plurality of parking spaces ( 4 ) and the camera device ( 10 ) is centrally arranged.

5. A method for operating a charging/discharging station ( 2 ) for charging or discharging an at least partially battery-operated vehicle ( 14 ) via an inductively coupled pair of coils, the charging/discharging station ( 2 ) having at least one parking space ( 4 ) with a primary coil ( 6 ), the primary coil ( 6 ) being able to form the inductively coupled pair of coils together with a secondary coil ( 18 ) of a vehicle ( 14 ) to be discharged and/or charged, the charging/discharging station ( 2 ) having a first communication unit ( 8 ) which is set up to communicate with a second communication unit ( 16 ) of the vehicle ( 14 ), and the charging/discharging station ( 2 ) having at least one camera device ( 10 ) which is connected to a computer device ( 12 ) for the purpose of processing recorded image data, wherein the camera device flies autonomously above the parking spaces, the method comprising the steps of:
a) determining and storing spatial coordinates of the parking space(s) ( 4 ) of the charging/discharging station ( 2 ) in the computer device ( 12 ),
b) identifying the vehicle ( 14 ) and detecting a current position of the vehicle ( 14 ) with respect to one or more parking spaces ( 4 ) of the charging/discharging station ( 2 ) by means of image data relating to the vehicle ( 14 ) which are recorded by the camera device ( 10 ), and
c) navigating the vehicle ( 14 ) to a parking space ( 4 ) on the basis of the detected current position of the vehicle ( 14 ) and the spatial coordinates of the parking space ( 4 ) by means of the first and second communication units ( 8 , 16 ).

6. The method as claimed in claim 5 , characterized in that the current position of the vehicle ( 14 ) is detected by means of a marking or by means of reference values of the vehicle ( 14 ).

7. The method as claimed in claim 5 , characterized in that the vehicle ( 14 ) is navigated to the parking space ( 4 ) in step c)
d) by transmitting coordinates of the parking space ( 4 ) relative to the vehicle ( 14 ) by means of the first and second communication units ( 8 , 16 ), a trajectory from the current position of the vehicle ( 14 ) to the parking space ( 4 ) being calculated in the vehicle.

8. The method as claimed in claim 5 , characterized in that the charging/discharging station ( 2 ) has a plurality of parking spaces ( 4 ), the computer device ( 12 ) providing a driver of the vehicle ( 14 ) with a selection of the parking spaces ( 4 ) after detecting the current position of the vehicle ( 14 ) with respect to the plurality of parking spaces ( 4 ), and the driver being able to select a parking space ( 4 ) to which the vehicle ( 14 ) is navigated according to step c).

9. The method as claimed in claim 8 , characterized in that the computer device ( 12 ) detects an occupancy state of the plurality of parking spaces ( 4 ) and provides only free parking spaces ( 4 ) for selection.

10. The charging/discharging station ( 2 ) as claimed in claim 1 , characterized in that the camera device ( 10 ) is positioned with respect to the parking space ( 4 ) in such a manner that a plan view of the parking space ( 4 ) is possible and approach routes of the vehicle ( 14 ) are visible.

11. The method as claimed in claim 5 , characterized in that the vehicle ( 14 ) is navigated to the parking space ( 4 ) in step c)
e) by calculating a trajectory from the current position of the vehicle ( 14 ) to the parking space ( 4 ) in the charging/discharging station ( 2 ) and by transmitting the calculated trajectory by means of the first and second communication units ( 8 , 16 ).
