Abstract
In a method for determining the drawbar length of a trailer of a tractor vehicle with a front-axle steering system for adjusting a front-axle steering angle and optionally additionally a rear-axle steering system for setting a rear-axle steering angle, an estimated value for the drawbar length is determined with an estimation method from an articulation angle, as detected by a sensor, between the trailer and the tractor vehicle on the basis of the front-axle steering angle and optionally the rear-axle steering angle, and the movement variables speed and yaw rate of the tractor vehicle.
