Abstract
The present invention relates to a control method and control apparatus for controlling actuator apparatus implemented in active suspension apparatus for vehicles, in particular rail vehicles, said control method and said control apparatus being characterized in that they use the articulated architecture of the train to derive the local curvature of the track in real time, in which control method and control apparatus the control signal transmitted by said control apparatus to the actuator apparatus of the bogie of order n in the articulated train is a function of measurements of at least one deflection angle &agr;i at an articulation center situated between adjacent carriages and of the position offset hj of said articulation center relative to the track.
