ABSTRACT:
A method and apparatus for damping steering movements, especially of a motorcycle, in which a steering damper is activated by an electronic evaluation circuit. The evaluation circuit receives signal from an angle sensor, an acceleration sensor and a velocity sensor. It compares the measured values of these sensors with predetermined constant values. If the measured value of the angle sensor and of the velocity sensor exceed their respective threshold value, then the evaluation circuit activates a damping device and increases the damping value of the steering damper. Independently or in conjunction therewith, the evaluation circuit activates the damping device when the measured value of the acceleration sensor exceeds a predetermined value. The method and apparatus prevents steering chatter and steering flutter.
