Abstract
In a suspension for a motor vehicle having at least one front axle and at least one rear axle, at least two vibration dampers which are separated from one another by a longitudinal axis of the vehicle are arranged at each axle. The sum of the occurring damping forces of the vibration dampers can be adjusted, and a vibration damper with adjustable damping force and a nonadjustable vibration damper are arranged at least at one vehicle axle.

Suspension for a motor vehicle having a front axle, a rear axle, a longitudinal axis, and a transverse axis, the suspension comprising at least two vibration dampers separated by the longitudinal axis on each axle, each vibration damper having a damping force, the sum of the damping forces being adjustable, at least one of the vibration dampers being nonadjustable.
A method for controlling a suspension for a motor vehicle having a front axle, a rear axle, a longitudinal axis, and a transverse axis, the suspension comprising at least two vibration dampers separated by the longitudinal axis on each axle, each vibration damper having a damping force, the sum of the damping forces being adjustable, at least one of the vibration dampers being nonadjustable, the method comprising:
- acquiring at least one vehicle state parameter;
- determining the damping force for the at least one nonadjustable vibration damper on the basis of said at least one vehicle state parameter;
- and
- determining the desired damping forces for the adjustable vibration dampers based on the damping force for the at least one nonadjustable vibration damper and the at least one vehicle state parameter.
