Abstract

The promising advent of Fully Electric Vehicles (FEVs) also means a shift towards fully electrical control of the existing and new vehicle functions. In particular, critical X-by-wire functions require sophisticated redundancy solutions. As a result, the overall Electric/Electronic (E/E) architecture of a vehicle is becoming even more complex and costly. The SafeAdapt project provides an integrated approach for engineering such adaptive, complex and safe systems, ranging from tool chain support, reference architectures, system modeling and networking, up to early validation and verification. In this paper, we give an overview of the SafeAdapt project methodology. We also describe a particular aspect of the project which is the validation of the system adaptive behavior. To validate the adaptive behavior of a vehicle system, an architecture description language for automotive embedded systems (i.e. EAST-ADL) is used for designing the system. The system design model is then used for generating the embedded software. To ensure that the system behaves correctly at runtime, its adaptive behavior is analyzed using fault injection and monitoring techniques on a virtual platform.
