Abstract: For regulating the driving dynamics of a road vehicle, setpoints for the yaw rate {dot over (&PSgr;)} and the float angle &bgr; of the vehicle are generated continuously by evaluating a simulation computer implemented vehicle model. The simulation computer generates control signals for activating at least one wheel brake of the vehicle based on a comparison of the reference values {dot over (&PSgr;)}SO as a setpoint, and the actual values {dot over (&PSgr;)}I of the yaw rate continuously recorded by a yaw rate sensor. The vehicle model is represented by a linear differential equation system of the form [P]·({overscore ({dot over (X)})})=[Q]·({overscore (X)})+({overscore (C)})·&dgr;(t).

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).

Abstract: A control arrangement for a follow-up steering axle in single- or multiple-unit vehicles with at least three axles. The follow-up steering axle may be stabilized in dependence upon a load of the vehicle in a direction toward a straight-ahead driving position and may be blocked in the straight-ahead driving position. A speed-dependent stabilization is provided for the follow-up steering axle in a direction toward its straight-ahead driving position.
