Abstract
In a method for semiactive chassis control, in particular for damping resilient wheel suspension systems in vehicles, having a piston displaceable in a cylinder and subdividing it into two work chambers, the cylinder and piston are each connected to a vehicle body or a wheel axle. At least one valve that controls the flow of pressure fluid into and out of the work chambers is associated with the work chambers. Control of the valve is effected as a function of an absolute vertical speed of the vehicle body and of a zero crossover of the relative speed of the relative motion between the axle or wheel in the vehicle body and/or of a zero crossover of the damper force and/or of a zero crossover of the differential pressure at the damper piston.
