Abstract: A method is for determining a controller output variable of a control unit having a controller for a controlled system, more particularly for manual torque control of a steer-by-wire steering system for a vehicle. The method includes adjusting a specified controller property of the controller using a specified adjustment portion, and continuously changing an influence of the specified adjustment portion on the controller property based on a parameter. The parameter is determined based on an operating situation of the controlled system, more particularly a steering and/or driving situation of the vehicle. The controller output variable is determined using the controller.

Abstract: In a device and method for determining a filter output variable of a filter, in particular of a filter for filtering a torsion bar moment of a steer-by-wire steering system of a vehicle, as a function of a filter input variable to be filtered, a predefined filter property of the filter is selected from a plurality of predefined filter properties depending on an input signal characteristic of the filter input variable. The input signal characteristic is determined depending on the filter input variable at a current point in time and at least one previous point in time, and the filter output variable of the filter is determined using the filter property.
