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.

Abstract: A damping arrangement of an active chassis for an axle of a motor vehicle, wherein a damping system cooperates with each wheel of the axle. Each of the damping systems includes a damper having a double-acting hydraulic cylinder and a piston. The damper is couplable to a wheel suspension system of the respective wheel. A hydraulic pump and an electric motor drives the respective hydraulic pump, wherein the hydraulic pump is driven by the electric motor in different directions of rotation to provide different conveying directions. A hydraulic unit includes a hydraulic reservoir and valves, wherein the hydraulic pump and the hydraulic unit of the respective damping system cooperate with hydraulic chambers of the hydraulic cylinder of the respective damping system, such that, depending on the conveying direction of the hydraulic pump, a movement of the piston in either a first or second actuation direction can be provided.

Abstract: A method for operating a damper system of a vehicle having an active damper and a hydraulic assembly arranged to control the damper. The hydraulic assembly includes a hydraulic pump and at least one control valve. Requirements placed upon the damper are defined with regard to the dynamics and force that are to be set. Depending on the defined requirements, the hydraulic pump of the hydraulic assembly operates at a minimum rotary speed and a defined opening setting of the at least one control valve. Based on the minimum rotary speed of the hydraulic pump and the defined opening settings of the control valve, a dynamic force setting of the damper takes place by way of a change of the opening setting of the at least one control valve. Alternatively or additionally, a high-value force setting of the damper takes place by changing the rotary speed of the pump.
