Abstract

A principle for handling system failure situations thereby maintaining minimum fault recovery time and providing high system availability is described, especially for controlling the system behavior in fault situations of Electronic Control Units used in automotive vehicles. This principle is providing unique solutions for fault analysis, fault recovery definition and system re-vitalization. It is a key attribute of the principle keeping the demand for hardware and software overhead at a minimum. The method applies graceful degradation of system functionality, allowing to achieve the implementation of cost effective systems.
