Model-Based Supervision and Control of Lateral Vehicle Dynamics

Abstract The further improvement of drive dynamic control needs model-based concepts. Two model-based applications are described. Firstly, the one-track model is used to indicate critical driving situations like oversteering or unstable behavior. Experiments with a middle-class vehicle show the results of this supervision and fault detection method. Secondly, it is shown by simulation how the understeering and oversteering behavior can be influenced by anti-roll bar actuation. Then a nonlinear yaw-rate controller for active steering is designed and it is shown by simulation how the steering behavior can be improved by anti-roll actuation.
