1. A control unit for a vehicle, wherein the control unit is operatively configured to:
- determine one or more properties of an electromagnetic interference field; and
cause a transmitting unit of the vehicle to emit an opposing field which reduces a field strength of the interference field in a first region around and/or in the vehicle;
wherein the control unit is operatively configured to determine the opposing field in such a way that a destructive interference results from a superimposition of the opposing field with the interference field in the first region.

Abstract
A device and a corresponding method are provided for reducing an electromagnetic field in a vehicle. A control unit for a vehicle is designed to determine one or more properties of an electromagnetic interference field. The control unit is further designed to incite an emission unit in the vehicle to emit an opposing field which reduces a strength of the interference field in a first zone around and/or in the vehicle.

7. A control unit for a vehicle, wherein the control unit is operatively configured to:
-
determine one or more properties of an electromagnetic interference field; cause a transmitting unit of the vehicle to emit an opposing field which reduces a field strength of the interference field in a first region around and/or in the vehicle; and alter the opposing field in order to reduce the interference field in a second region around and/or in the vehicle, wherein the second region comprises at least one location around and/or in the vehicle which is not contained in the first region.

9. A method for neutralizing an electromagnetic interference field in and/or around a vehicle, wherein the method comprises the acts of:
-
determining one or more properties of the interference field; and emitting an opposing field which reduces a field strength of the interference field in a first region around and/or in the vehicle; wherein the opposing field is determined in such a way that a destructive interference results from a superimposition of the opposing field with the interference field in the first region.
