Abstract
A method of controlling a hydraulic actuator of an active spring damper element in a vehicle for damping a relative movement between a vehicle structure and a wheel suspension. A hydraulic arrangement is provided for controlling the hydraulic actuator, which includes a hydraulic pump and at least one control valve. In a first method step, a relative movement between the vehicle structure and wheel suspension is detected. A force to be provided by the hydraulic actuator and a volume flow to be provided by the hydraulic pump are determined based on the detected relative movement. Then, a speed of the hydraulic pump is set to provide the volume flow required for the position of the force.
