Abstract

A vehicle has a charging device for charging an energy store at a charging station. The charging device has a vehicle-side coupling element for coupling to a charging-station-side coupling element. A control unit is provided is arranged in the region of the vehicle-side coupling element for maneuvering the vehicle.

Claims

1. A vehicle comprising:

an energy store;

an electric machine configured to receive power from the energy store and to drive at least one wheel of the vehicle;

a charging device for charging the energy store at a charging station, the charging device having a vehicle-side coupling element configured for coupling to a charging-station-side coupling element; and

a control unit connected to the electric machine and configured to cause the electric machine to maneuver the vehicle relative to the charging station, the control unit being arranged in the region of the vehicle-side coupling element and being accessible from the outside of the vehicle.

2. The vehicle of claim 1, wherein the charging device comprises a charging cable and/or a charging socket integrated into the vehicle.

3. The vehicle of claim 2, wherein the control unit is arranged on the charging cable and/or on the charging socket of the vehicle.

4. The vehicle of claim 1, wherein the control unit comprises an input device and/or an information playback device.

5. The vehicle of claim 1, wherein the vehicle comprises a monitoring device for monitoring a state of the vehicle.

6. The vehicle of claim 1, further wherein the control unit is arranged directly on the vehicle-side coupling element.

7. The vehicle of claim 1, wherein the control unit includes a user input device.

8. The vehicle of claim 1 further comprising a driver'"'"'s seat, the control unit being configured to sense whether the driver'"'"'s seat is occupied and permitting maneuvering of the vehicle only when the driver'"'"'s seat is not occupied.

9. A system for charging an energy store of a vehicle comprising a stationary charging station and a vehicle with an energy store, an electric machine configured to receive power from the energy store and to drive at least one wheel of the vehicle, a charging device for charging the energy store of the vehicle when the vehicle is at the charging station, the charging device having a vehicle-side coupling element configured for coupling to a charging-station-side coupling element;

and a control unit connected to the electric machine and configured to cause the electric machine to maneuver the vehicle relative to the stationary charging station, wherein the control unit is arranged in the region of the vehicle-side coupling element and is accessible from outside the vehicle.

10. A method for charging an energy store of a vehicle having a charging device, the method comprising:

moving the vehicle into a first position relative to a charging station; and

then using a control unit arranged in a region of the charging device and accessible from a location external of the vehicle for maneuvering the vehicle into a second position relative to the charging station; and

then charging the energy store of the vehicle.

11. The method of claim 10, further comprising determining whether a driver'"'"'s seat of the vehicle is occupied, and preventing use of the control unit for maneuvering the vehicle into the second position if the driver'"'"'s seat of the vehicle is occupied.

12. The method of claim 10, further comprising using a monitoring device on the vehicle for monitoring locations of objects in proximity to the vehicle and distances between the vehicle and the objects, and then using the locations and the distances determined by the monitoring device for controlling the maneuvering of the vehicle to the second position.
