Abstract

A stabilization apparatus for a two-wheeled vehicle includes a rotationally mounted gyroscope and a drive unit, as well as a rotational-direction reversal unit disposed between the drive unit and the gyroscope.

First claim

What is claimed is:

1. A stabilization apparatus for a two-wheeled vehicle, comprising:
a rotationally mounted gyroscope;
a drive unit, wherein the drive unit is configured to drive the gyroscope; and
a rotational-direction reversal unit, wherein the rotational-direction reversal unit is configured to adjust a direction of rotation of the gyroscope;
wherein:
the rotational-direction reversal unit is disposed between the drive unit and the gyroscope;
the rotational-direction reversal unit is a switchable gear unit;
the drive unit is a mechanical energy store or includes an electric motor;
the gyroscope is configured to be braked via a braking device;
a spin axis of the gyroscope is non-adjustable relative to the two-wheeled vehicle;
the spin axis of the gyroscope is angularly offset from spin axes of both wheels of the two-wheeled vehicle; and/or
the stabilization apparatus has exactly one gyroscope.

2. The stabilization apparatus as recited in claim 1 , wherein the rotational-direction reversal unit is the switchable gear unit.

3. The stabilization apparatus as recited in claim 1 , wherein the drive unit is the mechanical energy store.

4. The stabilization apparatus as recited in claim 3 , wherein the drive unit is a spiral spring.

5. The stabilization apparatus as recited in claim 1 , wherein the drive unit includes the electric motor.

6. The stabilization apparatus as recited in claim 1 , wherein the stabilization apparatus comprises the braking device.

7. The stabilization apparatus as recited in claim 1 , wherein the spin axis of the gyroscope is non-adjustable relative to the two-wheeled vehicle.

8. The stabilization apparatus as recited in claim 1 , wherein the stabilization apparatus has exactly one gyroscope.

9. The stabilization apparatus as recited in claim 1 , wherein the rotational-direction reversal unit is disposed between the drive unit and the gyroscope.

10. The stabilization apparatus as recited in claim 9 , wherein the drive unit is configured to output power, and the rotational-direction reversal unit is configured to supply the power output by the drive unit to the gyroscope to power the rotation of the gyroscope in the direction which the rotational-direction reversal unit is configured to adjust.

11. The stabilization apparatus as recited in claim 1 , wherein the drive unit is configured to output power, and the rotational-direction reversal unit is configured to supply the power output by the drive unit to the gyroscope to power the rotation of the gyroscope in the direction which the rotational-direction reversal unit is configured to adjust.

12. The stabilization apparatus as recited in claim 1 , wherein the spin axis of the gyroscope is angularly offset from the spin axes of both wheels of the two-wheeled vehicle.

13. The stabilization apparatus as recited in claim 12 , wherein the spin axis of the gyroscope coincides at least approximately with a vertical axis of the two-wheeled vehicle.

14. The stabilization apparatus as recited in claim 13 , wherein the stabilization apparatus is usable for yaw stabilization of the two-wheeled vehicle.

15. A regulating or control unit for controlling adjustable components of a stabilization apparatus, the stabilization apparatus including:
a rotationally mounted gyroscope;
a drive unit, wherein the drive unit is configured to drive the gyroscope; and
a rotational-direction reversal unit, wherein the rotational-direction reversal unit is configured to adjust a direction of rotation of the gyroscope;
wherein:
the rotational-direction reversal unit is disposed between the drive unit and the gyroscope;
the rotational-direction reversal unit is a switchable gear unit;
the drive unit is a mechanical energy store or includes an electric motor;
the gyroscope is configured to be braked via a braking device;
a spin axis of the gyroscope is non-adjustable relative to the two-wheeled vehicle;
the spin axis of the gyroscope is angularly offset from spin axes of both wheels of the two-wheeled vehicle; and/or
the stabilization apparatus has exactly one gyroscope.

16. A two-wheeled vehicle, comprising:
a stabilization apparatus including:
a rotationally mounted gyroscope;
a drive unit, wherein the drive unit is configured to drive the gyroscope; and
a rotational-direction reversal unit, wherein the rotational-direction reversal unit is configured to adjust a direction of rotation of the gyroscope;

a regulating or control unit; and
a vehicle sensor system;
wherein:
control signals for controlling adjustable components of the stabilization apparatus are able to be generated in the regulating or control unit from driving-condition variables ascertained in the vehicle sensor system; and
the rotational-direction reversal unit is disposed between the drive unit and the gyroscope, the rotational-direction reversal unit is a switchable gear unit, the drive unit is a mechanical energy store or includes an electric motor, the gyroscope is configured to be braked via a braking device, a spin axis of the gyroscope is non-adjustable relative to the two-wheeled vehicle, the spin axis of the gyroscope is angularly offset from spin axes of both wheels of the two-wheeled vehicle, and/or the stabilization apparatus has exactly one gyroscope.
