Abstract

A method for operating a rotating-mass device and a rotating mass device of a two-wheeled vehicle are provided. The rotating-mass device includes first and second gyroscopic instruments, each with a cardanically mounted rotating-mass device suitable for generating torque about their respective rotation axes. Pivoting of the rotating-mass devices is coordinated to influence motion of the two-wheeled vehicle about three orthogonal vehicle axes.

First claim

What is claimed is:

1. A method for operating a rotating mass device of a two wheeled vehicle having three orthogonal vehicle axes, the rotating mass device including a first gyroscope instrument and a second gyroscope instrument,
the first gyroscope instrument having a first cardanically mounted rotating mass with a first rotational axis, the first rotating mass being configured to rotate in a controlled fashion in order to bring about a first angular momentum and the first rotational axis being pivotable in a controlled spatial fashion in order to bring about a first torque which acts on the two wheel vehicle,
the second gyroscope instrument having a second cardanically mounted rotating mass with a second rotational axis, the second rotating mass being configured to rotate in a controlled fashion in order to bring about a second angular momentum and the second rotational axis being pivotable in a controlled spatial fashion in order to bring about a second torque which acts on the two wheel vehicle,

comprising the acts of:
rotating the first rotating mass;
rotating the second rotating mass; and
pivoting the first rotational axis and the second rotational axis with respect to one another, such that
portions of the first torque and of the second torque about a first vehicle axis of the three vehicle axes add to form a continuous and constant predefined total torque, and
portions of the first torque and of the second torque about second and third vehicle axes of the three vehicles axes compensate one another.

2. The method as claimed in claim 1 , wherein
the first rotational axis and the second rotational axis are pivoted with respect to one another in a manner which avoids singularities.

3. The method as claimed in claim 2 , wherein
the first rotational axis and the second rotational axis are pivoted with respect to one another in a phase shifted manner.

4. The method as claimed in claim 1 , wherein
a first vehicle axis of the three vehicle axes is a roll axis, and
a second vehicle axis of the three vehicle axes is a pitch axis or a yaw axis.

5. The method as claimed in claim 4 , wherein
one or both of the first rotational axis and the second rotational axis are pivoted in a manner which compensates a vehicle movement.

6. The method as claimed in claim 5 , wherein
one or both of the first rotational axis and the second rotational axis are pivoted in a manner which influences an oblique position of the vehicle.

7. The method as claimed in claim 5 , wherein
one or both of the first rotational axis and the second rotational axis are pivoted in a manner which influences an adhesion potential of a vehicle tire.

8. A rotating mass device for a two-wheeled vehicle having three orthogonal vehicle axes, comprising:
a first gyroscope instrument;
a second gyroscope instrument; and
an electric control device,
wherein
the first gyroscope instrument includes
a first cardanically mounted rotating mass with a first rotational axis,
a first rotary drive configured to provide controlled rotation of the first rotating mass and generate a first angular momentum, and
a first pivoting drive configured to provide controlled spatial pivoting of the first rotational axis and generate a first torque, and

the second gyroscope instrument includes
a second cardanically mounted rotating mass with a second rotational axis,
a second rotary drive configured to provide controlled rotation of the second rotating mass and generate a second angular momentum, and
a second pivoting drive configured to provide controlled spatial pivoting of the second rotational axis and generate a second torque,

the electric control device is configured to control
rotation of the first rotating mass,
rotation of the second rotating mass, and
pivoting of the first rotational axis and the second rotational axis with respect to one another, such that portions of the first torque and of the second torque about a first vehicle axis of the three vehicle axes add to form a continuous and constant predefined total torque, and portions of the first torque and of the second torque about second and third of the three vehicles axes compensate one another.

9. A two wheeled vehicle having the rotating mass device as claimed in claim 8 .

10. A two wheeled vehicle having three orthogonal vehicle axes, comprising:
vehicle wheels; and
a rotating mass device, the rotating mass device including:
a first gyroscope instrument;
a second gyroscope instrument; and
an electric control device,

wherein
the first gyroscope instrument includes
a first cardanically mounted rotating mass with a first rotational axis,
a first rotary drive configured to provide controlled rotation of the first rotating mass and generate a first angular momentum, and
a first pivoting drive configured to provide controlled spatial pivoting of the first rotational axis and generate a first torque, and

the second gyroscope instrument includes
a second cardanically mounted rotating mass with a second rotational axis,
a second rotary drive configured to provide controlled rotation of the second rotating mass and generate a second angular momentum, and
a second pivoting drive configured to provide controlled spatial pivoting of the second rotational axis and generate a second torque,

the electric control device is configured to control
rotation of the first rotating mass,
rotation of the second rotating mass, and
pivoting of the first rotational axis and the second rotational axis with respect to one another, such that portions of the first torque and of the second torque about a first vehicle axis of the three vehicle axes add to form a continuous and constant predefined total torque, and portions of the first torque and of the second torque about second and third ones of the three vehicles axes compensate one another, and

the first vehicle axis is a roll axis and a second vehicle axis of the three vehicle axes is a pitch axis or a yaw axis.
