Abstract : Due to limited resources and stringent economical constraints in the automotive industry, error detection and recovery mechanisms of embedded systems are carefully selected. However, critical safety requirements and increasing software complexity motivate car makers to look for technical solutions to improve online software robustness. The challenge is to design a portable, customizable, and lowcost solution for fault tolerance by using differently classical techniques, such as redundancy and diversification. The main principle is to control rigorously which information and when it is necessary to get it; which instrumentation is necessary to perform fault tolerance and where to add this instrumentation in the source code. An approach to develop a defense software is proposed. The defense software is designed as an external customizable component, relying on control and observability mechanisms provided by an emergent standard for automotive software architecture AUTOSAR.
