A method sofeware and apparatus for suppressing high-frequency oscillations in the steered axles of a vehicle with a regulating device for regulating a steering angle on the basis of a setpoint that has been calculated. Active steering of this kind has the advantage that driving errors, within the scope of the physically possible, are prevented. However, the disadvantage is that as a result of the regulation of the steering angle, steering stiffness, and running-in behavior of the wheel, high-frequency oscillations of the wheel result around its vertical axis. The development of these oscillations is termed the shimmy effect. The shimmy effect is reliably prevented without adversely affecting the regulating quality of the steering angle by calculating the steering angle rate in a model of the steering and supplied it to the computer as an additional input value.
A method for suppressing high-frequency oscillations in a steered axle of a vehicle, wherein a regulating device at the steered axle acts to regulate a steering angle as a function of a setpoint that has been calculated with a computer in which, in a setpoint calculator, the setpoint is determined for the steering angle and supplied to the regulating device on the basis of a steering wheel angle specified at an actuator by a driver of the vehicle and at least one value characterizing a driving behavior of the vehicle, and further wherein a value for a steering rate is determined in the computer on the basis of a model for the steering and is supplied to the setpoint calculator as an additional input value to determine the setpoint.
