Safety framework and platform for functions of future automotive E/E systems

Abstract

This paper proposes a new safety framework and platform for the functions of future electrical/electronic (E/ E) systems. The framework aims to cope with the increasing complexity of the E/E systems, and to enhance their flexibility, but retain the safety properties and keep low engineering costs. A domain-specific meta-model is used to specify relevant aspects of the system such as component interface requirements and function descrip- tions. The meta-model is used in a tool that generates data structures, which are then used to configure the fault- management layer of the run-time environment. The fault- management layer preserves the safety properties of the system at run-time, by facilitating error detection and fault- handling mechanisms, and supporting controlled adapta- tion. By reusing already developed safety measures for different systems and functions, future development costs for non-functional qualities can be saved.
