ABSTRACT:
The disclosure relates to a jackknifing controlling system, for reducing undesirable jackknifing in an articulated vehicle, particularly with a rear drive. Sensing means is provided for measuring the angle of steering as well as the angle of articulation. At all times, the actual angle of articulation is compared to an ideal angle of articulation for the particular angle of steering, the ideal angle having been preprogrammed into a memory device. Whenever the actual angle of articulation deviates from the preprogrammed ideal angle by a predetermined amount, control actions are initiated to control the articulation. Further articulation in the direction of deviation is immediately blocked. Articulation in the opposite direction, toward the ideal, is freely allowed if the deviation exceeds a predetermined amount. If it is less than the predetermined amount, articulation, even toward the ideal angle is, damped by throttling of hydraulic flows. The range of deviation over which return articulation is damped follows a set of curves, embracing the curve of ideal articulation in an asymmetrical manner providing for optimum control over undesirable swinging.
