ABSTRACT:
When swaying motions of a trailer or semi-trailer of a car-trailer combination are encountered, input signals which are taken into consideration to calculate a reference signal frequently include also oscillation components, due to which driving dynamics control for stabilization of the car-trailer combination can become very unreliable. To enhance the reliability of driving dynamics control of this type, a method is disclosed in which an input signal (Y) is sensed that includes signal oscillations which are due to a swaying motion of the trailer or semi-trailer and are superimposed on a base component (YBasis) of the input signal (Y). A reference signal is calculated from the input signal (Y), in which case the calculation is executed in such a way that the reference signal by approximation corresponds to a reference signal which is determined from the base component (YBasis) of the input signal (Y). A correcting variable for influencing the driving behavior of the towing vehicle of the car-trailer combination is then determined depending on a deviation between the reference signal and a detected actual signal. Furthermore, the invention discloses a driving dynamics control system which is appropriate to implement the method.
