The Electric/Electronic architecture of vehicle becomes more complex and costly, self-adaption can reduce the system, enhance the adaptive meanwhile reduce energy consumption and costs. The self-adaption needs the cooperation of both hardware and software reconfigurations, such that after the software is reconfigured the automotive network continues to fulfill the time constraints for time-critical applications. The thesis focuses on the real-time network reconfiguration. It uses EAST-ADL to model a real-time automotive system with timing events and constraints, which conforms to AUTOSAR timing extensions. The network media access is analyzed based on the model and a scheduling algorithm is developed. Then the concept is implemented by a use case, which is transformed from an EAST-ADL model to an executable simulation.

Model-Driven Development is a development approach which is being used frequently in the automotive context in order to design models. EAST-ADL is an architectural language which models systems according to their architectural features, whereas Simulink is a tool environment which models systems according to their behavior. In this thesis work, we propose a set of transformation rules that take into consideration the EAST-ADL architectural model details and the behavioral specifications in Simulink, and generate a formal model, which can be verified UPPAAL model checker. Moreover, we implement these proposed transformation rules in a tool that automates them. The transformation rules proposed in this thesis work would be implemented for every EAST-ADL file with Simulink behavior specifications, generated by the MetaEdit+ tool. Properties like timing constraints, triggering and hierarchy in both EAST-ADL and Simulink have been considered by the transformation rules. Finally, the Brake-by-Wire case study is used to validate the tool and assess the mapping of the elements.
