Abstract
A vibration damping method on a vehicle wheel suspension is provided in which, in a hydraulic vibration damper, the damping force increases highly progressively as a function of the piston speed, especially in the range of a piston speed of essentially 0 to 2 m/s, increasing at first slowly and essentially linearly and then especially beyond a piston speed of essentially 2 m/s increasing highly progressively.
Claims8
A vibration damping method for a vehicle wheel suspension, comprising the acts of:
- adjusting a damping force of a hydraulic vibration damper as a function of damper piston speed, wherein in a piston speed range of essentially 0 to 2 m/s, the damping force increases essentially linearly as piston speed increases, and beyond a piston speed range of essentially 2 m/s the damping force increases in a highly progressive manner relative to the damping force increase in the essentially 0 to 2 m/s piston speed range.
