Abstract
A method of sensing the curvature of a routing or guide line used in automatic steering of a vehicle. The actual position of the vehicle with respect to the guide line is determined, and an estimated position of the vehicle with respect to the guide line is determined by means of a vehicle model. The actual and estimated positions are compared to obtain the difference between them, the difference being an indication of the curvature of the guide line.
