Abstract (en)
[origin: EP2371656A1] The vehicle (S) has axles (A1) i.e. wheel sets, rotatably supported around a rotating point, and actuators (AKT1, AKT2) connected to sides of the axles, respectively, where ends of the actuators are connected with a frame of the vehicle. Horizontal angle positions (alpha1, alpha2) of the respective axles opposite to the frame are adjusted by modulation of lengths of the actuators during the operation of the vehicle, such that a preset transverse displacement and a preset shaft angle (dalpha) are achieved, where the displacement and the angle are determined by a model-based method.
