A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve,—in which the presence of an unstable driving state in the vehicle lateral direction is detected and—as a function thereof, for the stabilization of the motor vehicle, at least one nozzle is activate
A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve,—in which the presence of an unstable driving state in the vehicle lateral direction is detected and—as a function thereof, for the stabilization of the motor vehicle, at least one nozzle is activated, through which a medium is emitted perpendicularly to the wheel plane of a vehicle wheel.

1. A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve, comprising: detecting a presence of an unstable driving state in a vehicle lateral direction; andas a function of the detecting, activating at least one actuator for stabilizing the motor vehicle
1. A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve, comprising: detecting a presence of an unstable driving state in a vehicle lateral direction; andas a function of the detecting, activating at least one actuator for stabilizing the motor vehicle, the activating causing a medium having a velocity component perpendicular to a wheel plane of a vehicle wheel to be emitted;wherein the unstable driving state is one of an oversteering and an understeering of the motor vehicle. 2. A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve, comprising: detecting a presence of an unstable driving state in a vehicle lateral direction;as a function of the detecting, activating at least one actuator for stabilizing the motor vehicle, the activating causing a medium having a velocity component perpendicular to a wheel plane of a vehicle wheel to be emitted; andascertaining a float angle of the motor vehicle, wherein an oversteering driving state is detected as present if the float angle exceeds a predefined limiting value. 3. The method as recited in claim 2, wherein, in the case of the oversteering driving state, a nozzle attached to a rear wheel suspension on an outside of the curve is activated, via which the medium having the velocity component pointing in a direction of the outside of the curve is emitted. 4. The method as recited in claim 2, wherein in addition, a steering angle of the motor vehicle is ascertained and an understeering driving state is detected as present if the steering angle exceeds a predefined limiting value and simultaneously the float angle falls below a predefined limiting value. 5. The method as recited in claim 4, wherein, in the case of the understeering driving state, a nozzle attached to a front wheel fork on an outside of the curve is activated, via which the medium having the velocity component pointing in a direction of the outside of the curve is emitted. 6. A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve, comprising: detecting a presence of an unstable driving state in a vehicle lateral direction; andas a function of the detecting, activating at least one actuator for stabilizing the motor vehicle, the activating causing a medium to be emitted, wherein the medium has a velocity component perpendicular to a wheel plane of a vehicle wheel and a velocity component directed in parallel to the wheel plane pointing in an upwardly directed vertical direction of the single-track motor vehicle. 7. A device for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve, comprising: a sensor for detecting a presence of an unstable driving state in a vehicle lateral direction; anda controller for, as a function of the detecting, activating at least one actuator for stabilizing the motor vehicle, wherein the activating causes a medium to be emitted, the emission generating a force that acts on a wheel of the vehicle and that includes a velocity component acting on the wheel perpendicularly to a wheel plane of the wheel. 8. A method for lateral dynamic stabilization of a single-track motor vehicle while negotiating a curve, comprising: detecting a presence of an unstable driving state in a vehicle lateral direction; andas a function of the detecting, activating at least one actuator for stabilizing the motor vehicle, wherein the activating causes a medium to be emitted, the emission generating a force that acts on a wheel of the vehicle and that includes a velocity component acting on the wheel perpendicularly to a wheel plane of the wheel. 9. The method as recited in claim 8, wherein the medium includes one of carbon dioxide, nitrogen, helium, and compressed air, and wherein the medium is stored in a pressure vessel. 10. The method as recited in claim 8, wherein the medium is a combustion product created by a local combustion carried out close to a nozzle and is emitted through a nozzle opening. 11. The method as recited in claim 8, wherein, in parallel to the activation of the actuator, one of a steering damper and a steering torque actuator acting on a front wheel is activated. 12. The method as recited in claim 8, wherein: the detecting includes detecting a critical driving maneuver that includes (a) an unstable negotiating of a curve, (b) a critical understeering, (c) a critical oversteering, or (d) a combination of two or more of (a)-(c); andthe activation is in response to the detection of the critical driving maneuver. 13. The method as recited in claim 12, further comprising: activating a steering damper or a steering torque actuator that acts on a front wheel in response to the detection of the critical driving maneuver in response to which the activation causing the medium emission is performed. 14. The method as recited in claim 12, wherein the critical driving maneuver includes the unstable negotiating of the curve. 15. The method as recited in claim 12, wherein the critical driving maneuver includes the critical understeering. 16. The method as recited in claim 15, wherein the critical understeering is detected by detection of simultaneous presence of a float angle below a float angle threshold and a steering angle above a steering angle threshold. 17. The method as recited in claim 16, wherein the steering angle threshold is speed dependent. 18. The method as recited in claim 12, wherein the critical driving maneuver includes the critical oversteering. 19. The method as recited in claim 18, wherein critical oversteering is detected by detection of a float angle that is above a threshold. 20. The method as recited in claim 19, wherein the threshold is speed dependent.
