The ESP (Electronic Stability Program) is a driving dynamical control system that is used to support a driver in critical driving situations. A basic component integrated in the ESP system is an on-line sensor monitoring system that is used for detecting faults in sensors as early as possible to prevent a fail control. A model-based sensor monitoring scheme is presented for the ESP system that is developed and produced in series by the company Continental Teves (Frankfurt/Main, FRG). A multi-model given in form of redundant sub-models is used for the construction of analytical redundancy, residual generation as well as residual evaluation. Furthermore, the driving situation depending adaptive thresholds are established. Test results of the yaw rate sensor in the presence of a fault during driving straight on and during a slalom maneuver are presented.
