Then, a speed of the hydraulic pump is set to provide the volume flow required for the position of the force.

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.

Abstract: A method for detecting a distortion of a light pattern defining a code word includes projecting a light pattern onto an object via a light source and detecting the projected light pattern and comparing the detected light pattern with a reference light pattern. The reference light pattern has individual, spaced-apart light pattern elements arranged in a plurality of successive columns in the direction of a first extension axis and the number and/or position of the at least one light pattern element in each column of the reference light pattern is an encoding feature that defines at least one code word.
