Abstract
A control device for an articulated road train provided with a system for detecting pivoting and articulating angles between the central longitudinal axes of the tractor and a semi-trailer coupled thereto by a coupling pin during coupling and parking and/or a control device for an articulated road train provided with a system for detecting pivoting and articulating angles between the central longitudinal axes of a drawbar and a trailer which is coupled by the drawbar during coupling and parking. The system has a plurality of Hall sensors () arranged side-by-side on the arc of a circle and a constant magnet () interacting therewith in such a way that it acts on the nearest Hall sensor according to the radial position thereof, a required angle (α) being determined on the basis of the excited Hall sensor position.
