Abstract

A device for exerting torque on an object includes: at least one rotating mass rotatably supported about an axis of rotation; a drive for driving the rotating mass; a bearing which enables a change in the alignment of the axis of rotation relative to the object; and a coupling unit which engages on the bearing and couples the rotating mass to the object.

Claims

1-12. -12. (canceled)

13. A device for exerting torque on an object, comprising:

at least one rotating mass rotatably supported about an axis of rotation;

a drive for driving the rotating mass;

a bearing for supporting the rotating mass on the object, wherein the bearing permits a change in the alignment of the axis of rotation relative to the object; and

a coupling unit which engages on the bearing, wherein the at least one rotatably supported rotating mass is able to be selectably coupled to the object using the coupling unit and selectably decoupled from the object.

14. The device as recited in claim 13, wherein the bearing includes a Cardanic suspension.

15. The device as recited in claim 13, wherein the coupling unit is configured for at least one of fixing the bearing in position and releasing of the bearing.

16. The device as recited in claim 13, wherein the coupling is configured so that the position of the axis of rotation of the rotating mass is able to be changed in the coupled state.

17. The device as recited in claim 16, wherein a brake is provided for exerting a braking force on the rotating mass.

18. The device as recited in claim 14, wherein at least one body having six rotating masses is provided and supported Cardanically relative to the object using the bearing, in each case two rotating masses being rotatable about the same axis of rotation in opposite directions.

19. The device as recited in claim 18, wherein the object is a vehicle.

20. A method for exerting torque on an object using a device for exerting torque on an object, the device including at least one rotating mass rotatably supported about an axis of rotation;

a drive for driving the rotating mass;

a bearing for supporting the rotating mass on the object, wherein the bearing permits a change in the alignment of the axis of rotation relative to the object; and

a coupling unit which engages on the bearing, wherein the at least one rotatably supported rotating mass is able to be selectably coupled to the object using the coupling unit and selectably decoupled from the object, the method comprising;

recording data on a stability state of the object, using at least one sensor;

ascertaining from the recorded data whether the stability state is critical;

ascertaining a counter-torque to be transmitted to the object for stabilizing the object;

ascertaining a torque that is to be exerted on at least one of the rotating masses, in order to effect the desired counter-torque, and exerting the torque on at least one of the rotating masses, if the stability state has been ascertained as critical.

21. The method as recited in claim 20, wherein the bearing is fixed in position, and at least one rotating mass is one of braked or accelerated if the stability state has been ascertained as critical.

22. The method as recited in claim 20, wherein, for changing the alignment of the axis of rotation of at least one rotating mass, the position of the bearing is adjusted with the aid of a drive, at the coupling unit.

23. The method as recited in claim 21, wherein the object is a vehicle, and at least one of an acceleration, a rate of rotation, a steering angle, and a wheel speed is recorded as the data on the stability state.
