Fault Tolerance in Safety Critical Automotive Applications: Cost of Agreement as a Limiting Factor

The high availability and safety requirements for automotive electronics are currently almost exclusively addressed by application-specific engineering solutions to fault tolerance rather than by systematic approaches. Currently, syst e m i c approaches are ruled out because of cost. The reason for this is that a systemic approach to fault tolerance requires ( I ) replication of components and ...

Non-intrusive System Level Fault-Tolerance

High-integrity embedded systems operate in multiple modes, in order to ensure system availability in the face of faults. Unanticipated state-dependent faults that remain in software after system design and development behave like hardware transient faults: they appear, do the damage and disappear. The conventional approach used for handling task overruns caused by transient faults is to use a s...

Middleware Support for Adaptive Dependability through Explicit Runtime Integrity Constraints

Integrity and availability are two competing dependability attributes. While some applications require strict integrity, other applications exist, e.g., safety or mission critical systems, where—depending on the specific situation— availability is more important for dependability than strict integrity. Within our work, we focus on data-centric systems, where availability can be increased by tem...

Fault Detection in Dynamic Systems: From State Estimation to Direct Input Reconstruction Methods FAULT DETECTION IN DYNAMIC SYSTEMS: FROM STATE ESTIMATION TO DIRECT INPUT RECONSTRUCTION METHODS

PREFACE Modern technology has increasingly created highly complex dynamical systems where the issues of systems' availability and operational safety have become one of the main problems: dependability and reliability became major concerns in the design of modern technical control systems. In engineering the term 'safety intensive' is used for denoting and characterizing these systems more close...
