Abstract

In a method and device for controlling driving dynamics, at least one steering action at a vehicle axle being controlled, a driving-dynamics setpoint, which is described by at least a yaw-dynamics setpoint, being ascertained, a steering-angle precontrol value being determined on the basis of the driving-dynamics setpoint, using a model of the controlled system, the driving state, which is described by at least the yaw rate, being ascertained, at least one steering-angle correction value being ascertained, based on the deviation of the actual yaw rate from a setpoint yaw rate, and the steering action being defined by the steering-angle precontrol value and the at least one steering-angle correction value.
