Abstract
The invention relates to a method for compensating for vertically oriented movements of a superstructure of a vehicle. The vehicle is provided with the superstructure and with an active undercarriage having a plurality of wheels which are in contact with the carriageway, wherein each wheel is connected via an actuator adjustable over its length at a wheel assigned to a suspension point with the superstructure. Vertically oriented movements of the superstructure are caused by an inclination of the carriageway and by unevennesses of the carriageway, a first change of the length of at least one actuator is carried out for frequencies in a first, lower frequency range, and a second change of the length of the at least one actuator is carried out for frequencies in a second, higher frequency range.
