Abstract

This invention relates to a method on a truck for railway vehicles to measure the curvature of a track and a method for configuring the steering orientation of an axle of a rail truck as a function of the curvature of the track, which axle is rotationally fastened to a truck frame. The curvature of the track is determined by dividing a yaw rate by a translation rate, and the wheels are oriented on the basis of a setpoint steering angle (&ggr;setpoint) which is calculated by multiplying the track curvature (&khgr;) by one-half the distance between the two axles of the truck.
