Diagnostic Coverage Estimation Method f...

In this paper we present a method to calculate estimated values fordiagnostic coverage and false alarm rates of two channel redundant sensorsystems. Avoiding timeconsuming methodologies going into detail ofsystem-sub-block failure rates and detailed fault cases we show a worst-caseapproach based on statistical methods. Diagnostic coverage and false alarmrates are important to develop a safety concept and to perform a functionalsafety analysis for sensor systems in safety critical applications. Theproposed methodology additionally enables global sensor system optimizationsincluding these dependability requirements..
