An anti-buckling control system is disclosed for articulated vehicles, especially articulated busses. Two double acting piston-cylinder units are interposed in the pivot connection between the forward and following vehicular units for applying resistance forces against hinged or buckling movement of the vehicular units with respect to one another. A computerized control unit is provided for controlling the hydraulic circuit for the piston-cylinder units so that they apply resistance forces tending to direct the buckling angle towards desired values determined in dependence upon the forward vehicular unit steering angle, the instantaneous buckling angle, and the vehicle velocity. The piston-cylinder units are disposed with their ends at one vehicle side closely adjacent one another and with their ends at the other vehicle side spaced from one another to form a V-shaped configuration. To increase the effectiveness of the piston-cylinder units for large buckling angles and the like, the ends thereof connected to a pivotal cross piece for supporting the following vehicle section, are disposed at the following vehicle side of the buckling pivot axis during straight driving conditions.
