Abstract
The invention is directed to a method and an arrangement for controlling an operating variable of a motor vehicle. A friction-burdened actuator assembly, which influences the operating variable, is actuated via a drive signal. This drive signal is formed on the basis of a desired value of the operating variable. The drive signal is additionally changed in response to a desired change of the operating variable to transfer the actuator assembly out of a steady state condition preferably so as to effect an actual change of the operating variable. In this way, the static friction of the actuator assembly, which is in opposition to the change of the operating variable, is overcome. Furthermore, the drive signal can be additionally changed in the sense of a reduction of the change of the operating variable when the operating variable approaches the desired value thereof.
