Patent ID: 8046147

Claim:
A method for stabilizing a car-trailer combination consisting of a towing vehicle and a trailer or semi-trailer comprising the following steps: detecting an input signal(Y;δ H ;{dot over (ψ)} meas ) with signal oscillations due to a swaying motion of the trailer or semi-trailer, the input signal (Y;δ H ;{dot over (ψ)} meas ) having a base component (Y Basis ;{dot over (ψ)} Basis ) superimposed by the signal oscillations, determining a reference signal ({dot over (ψ)} ref,corr ) correlating with an intermediate signal determined from the base component (Y Basis ;{dot over (ψ)} Basis ) of the input signal (Y;δ H ;{dot over (ψ)} meas ), determining a correcting variable (Δδ;ΔM) depending on a deviation (Δ{dot over (ψ)} Trailer ) between the reference signal ({dot over (ψ)} ref,corr ) and a detected signal ({dot over (ψ)} meas ), and influencing a driving condition of the towing vehicle according to the determined correcting variable (Δδ;ΔM).
