1. A system for undercarriage control of a vehicle, comprising:
- an adjustable damper including at least one adjustable damping valve for adjustment of a damping characteristic of the damper in at least two modes, said damper defining a tension and compression stage, said damper having a difference in damping force between two of said damping characteristic modes in one of said tension and compression stages, which is smaller than a difference in damping force between two of said damping characteristic modes in the other of said tension and compression stages; and
means for actuating the damping valve, said actuation only occurring during one of said tension and compression stages having said smaller difference in damping force.

Abstract
The damping characteristics of shock absorbers are variable contingent upon various operating parameters. In changing the damping characteristic, the invention provides for performing the change during operating phases of slight damping force changes. This can be achieved, in that the changes of the damping characteristic are carried out only in the compression stage of the shock absorber. This is especially favorable with a shock absorber of a design such that its damping characteristic will be adjustable only in the traction stage.

12. A method of actuating an adjustable damper in a vehicle, the damper including at least one adjustable damping valve for adjustment of a damping characteristic of the damper in at least two modes, the damper defining a tension and compression stage, said method comprising the steps of:
-
actuating the damping valve dependent on whether the damper is in a tension or compression stage; the improvement comprising; actuating the damping valve only during one of said tension and compression stages having a difference in damping force between two of said damping characteristic modes which is smaller than a difference in damping force between two of said damping characteristic modes in the other of said tension and compression stages. - View Dependent Claims (13, 14, 15, 16, 17)
