Abstract:
An arrangement for controlling an operating variable of a motor vehicle, the arrangement comprising:an electrically actuable actuator;a controller for driving said actuator in the context of a control loop having an operating range subdivided into first and second subranges and said controller having at least one changeable parameter (P, I, D);means for forming a desired value (DES) for said operating variable;means for detecting an actual value (ACT) of said operating variable;means for determining at least one of said subranges in dependence upon the magnitude of said actual value (ACT) and in dependence upon a magnitude of a change (.DELTA.DES) of said changeable desired value (DES);means for determining the value of said at least one parameter (P, I, D) in dependence upon the determined subrange; and,said controller generating a drive signal (S) in dependence upon said desired value (DES), said actual value (ACT) and said at least one parameter (P, I, D) of said controller for driving said actuator.
