ABSTRACT:
An apparatus for an articulated vehicle for preventing jackknifing. A sensor for sensing the steered angle has a movable first element coupled to the steered wheel and a stationary second element, one of the first and second elements being divided into sections starting from the position of the steering to the left, with a discrete signal for each single section referring to its relative position and having a value differing from that of the other sections and a digital output signal characteristic of the serial number of each section. A sensor for sensing the angle of articulation has a displaceable third element connected to one of the vehicle parts, and a stationary fourth element, wherein one of the third and fourth elements is divided into sections starting from the position of the fully left articulation with a digital output signal for each section representative of the serial number and a discrete signal representing the relative position thereof and which has a value which is different from that of the other sections. An angular position evaluating unit is receptive of the output signals from the two sensors for comparing same and for indicating a positive differential sign if the serial number of the steering angle section is less than the serial number of the section of the angle of articulation and the difference between the serial numbers is greater than a predetermined value and a negative differential sign if the serial number of the section of the steering angle is larger than the serial number of the section of the angle of articulation and the difference between the serial numbers is greater than a predetermined value.
