Using real-time and online models in vehicle control and fault diagnosis necessitates knowledge about time variant physical parameters and current driving situation. Detailed information about vehicle conditions, in form of a Characteristic Velocity Stability Indicator, is used to select the corresponding vehicle model structure for adaptive drive dynamic control. After a short introduction to a lateral vehicle model, a new approach for the online calculation of different driving conditions (i.e. stability, understeering, oversteering, and neutralsteering) is given.
Keywords: Vehicle dynamics, stability, driving situation, characteristic velocity
