Abstract

In this paper we have presented the design of a system for the detection of critical situations in driving car. This system was developed in a modular and flexible form in order to detect indexed failures. Each module addresses a specific defect. The principle is based on the use of a bank of observers combined with estimators. Residuals representing the difference between estimated and measured values are generated and compared using the sequential test of Wald. Three problems are discussed in this paper: over and under steering, suspension failure detection and variation of the tire pressure
