The increase in software functions and software complexity of automotive applications requires appropriate software architectures. A promising approach is the component architecture which also stands in the centre of the automotive standardisation project AUTOSAR. As every embedded real-time system inevitably has upper time bounds, we present an integrated method of timing estimation for highly flexible and variant applications based on a prototype component architecture. Therefore, we especially develop methods for parameterised timing estimation which depend on the grade of complexity, variability and necessary exactness. The feasibility of the introduced concept is shown in the prototype architecture and a prototype application.
