Abstract

In a method for stabilizing a two-wheeled vehicle during cornering, a drifting of the rear wheel or an understeering of the front wheel is inferred on the basis of measured values including the actual steering angle, and the two-wheeled vehicle is stabilized by altering the torque at the front wheel and/or the rear wheel.

First claim

What is claimed is:

1. A method that stabilizes a two-wheeled vehicle during cornering, comprising:
measuring at least one driving state value including an actual steering angle;
inferring, based on the at least one driving state value, one of a drifting of a rear wheel or an understeering of a front wheel; and
stabilizing the two-wheeled vehicle by altering a torque at least one of at the front wheel and at the rear wheel.

2. The method as recited in claim 1 , wherein the at least one driving state value further includes measured acceleration values, and wherein a critical driving state is inferred from the measured acceleration values and the actual steering angle.

3. The method as recited in claim 2 , wherein a nominal steering angle is ascertained and, from a deviation between the actual steering angle and the nominal steering angle, the one of the drifting of the rear wheel or the understeering of the front wheel is inferred.

4. The method as recited in claim 3 , wherein the nominal steering angle is ascertained from an angle of inclination and a vehicle velocity.

5. The method as recited in claim 4 , wherein the angle of inclination is calculated from measured acceleration values.

6. The method as recited in claim 4 , wherein a maximum allowable drift angle is specified.

7. The method as recited in claim 4 , wherein a driving style is selected and specified among multiple driving styles.

8. The method as recited in claim 3 , wherein a braking torque at the at least one of the front wheel and the rear wheel is altered.

9. The method as recited in claim 3 , wherein an engine torque acting on the rear wheel is altered.

10. A regulating unit that stabilizes a two-wheeled vehicle during cornering, comprising:
a control unit including a processor configured to perform the following:
measuring at least one driving state value including an actual steering angle;
inferring, based on the at least one driving state value, one of a drifting of a rear wheel or an understeering of a front wheel; and
stabilizing the two-wheeled vehicle by altering a torque at least one of at the front wheel and at the rear wheel.

11. A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method that stabilizes a two-wheeled vehicle during cornering, the method comprising:
measuring at least one driving state value including an actual steering angle;
inferring, based on the at least one driving state value, one of a drifting of a rear wheel or an understeering of a front wheel; and
stabilizing the two-wheeled vehicle by altering a torque at least one of at the front wheel and at the rear wheel.
