Abstract

An influencing device for influencing an active chassis that includes a plurality of controllable spring or damper units of a vehicle is provided. The influencing device includes a roadway sensor that produces sensor data relating to a roadway located in front of the vehicle in a direction of travel, the sensor data being used to acquire a roadway profile. The influencing device also includes a pilot control unit that determines, as a function of the acquired roadway profile, a pilot control variable that is used to adapt the setting of the spring or damper units to the acquired roadway profile. An input signal for a vehicle body control system, which is used to control the position of the vehicle body, is calculated on the basis of the pilot control variable.
