Abstract

In a method for stabilizing a vehicle motion of a single-track motor vehicle, e.g., a motorcycle, an angle of inclination of the motor vehicle relative to the roadway is recorded via inclination sensors and, after the processing of the angle of inclination in a computing device, a control signal based on this is supplied to a control device for bringing about a stabilization intervention in the vehicle motion, the attitude angle of the motor vehicle being recorded and jointly processed in the control device, using at least one attitude angle recording sensor.

Claims

1-9. -9. (canceled)

10. A method for stabilizing a vehicle motion of a single-track motor vehicle, comprising:

recording, using at least one inclination sensor, an angle of inclination of the motor vehicle relative to a roadway;

recording, using at least one attitude angle recording sensor, an attitude angle of the motor vehicle;

jointly processing the angle of inclination information and the attitude angle information in a computing device to generate a control signal; and

supplying the control signal to a control device to implement a stabilization intervention in the vehicle motion of the motor vehicle.

11. The method as recited in claim 10, further comprising:

recording the speed of the motor vehicle, wherein the recorded speed is jointly processed in the computing unit along with the angle of inclination information and the attitude angle information.

12. The method as recited in claim 11, wherein a time curve of the attitude angle is recorded and is jointly processed in the computing unit along with the angle of inclination information and the attitude angle information.

13. The method as recited in claim 11, wherein the control signal implements at least one of:

a disengagement of the engine;

a braking intervention;

an engine drive torque reduction; and

an active suspension control.

14. The method as recited in claim 11, wherein the attitude angle recording sensor ascertains a tire slip angle at one wheel of the motor vehicle, and wherein the tire slip angle is jointly processed in the computing device along with the angle of inclination information and the attitude angle information.

15. The method as recited in claim 13, wherein the attitude angle recording sensor is a radar sensor.

16. The method as recited in claim 13, wherein the control device implements the stabilization intervention based on the control signal only if a boundary value is exceeded.

17. The method as recited in claim 16, wherein the boundary value is preset in a fixed manner.

18. A device for stabilizing a vehicle motion of a single-track motor vehicle, comprising:

at least one inclination sensor for recording an angle of inclination of the motor vehicle relative to a roadway;

at least one attitude angle recording sensor for recording an attitude angle of the motor vehicle;

a computing device for jointly processing the angle of inclination information and the attitude angle information to generate a control signal; and

a control device receiving the control signal from the computing device and implementing a stabilization intervention in the vehicle motion of the motor vehicle based on the control signal.
