An AADL-based approach to variability modeling of automotive control systems

While the complexity of automotive systems is increasing, nowadays, most of the newly developed functionalities are implemented by software. This implies that software plays an important role in the development of automotive systems. However, several inefficiency problems related to software remain unresolved. One problem is to find an effective way to handle a large-scale variation of automotive systems. Hence, this paper presents an AADL (Architecture Analysis & Design Language)-based approach to the variation-related problem. The proposed approach captures the variation of automotive systems and yields their variability models. The obtained models promote an efficient development that exploits system variation. In this paper, we explain the detailed procedure of AADL-based development with the help of an example of development of cruise control systems.
