Abstract

A buckling protection control system for articulated vehicles, especially for articulated buses is disclosed. Double acting piston cylinder units are interposed between vehicular sections at the hinged connection therebetween to forceably dampen and control the relative angular movement of the vehicular sections during driving of the vehicle. In addition to controlling the buckling movements during proper driver operation of the vehicle, the control system of the invention includes an arrangement for responding to situations where a driver, as a result of a panic reaction, sharply or rapidly steers the vehicle. For this purpose, the invention includes a computer control system which determines a maximum buckling angle value K-max(V) which is dependent on the vehicle velocity V. Irrespective of other driving conditions, the buckling angle is prevented from exceeding this maximum buckling angle K-max(V).
