Automated Continuous Evaluation of AUTOSAR Software Architecture for Complex Powertrain Systems

Abstract

Connectivity of the vehicle to heterogeneous information sources is one of the key factors which lead to complexity of automotive software architecture. The information content from external communication sources modifies the structure, content and the synchronization of control algorithms. In addition to this, time and cost constraints for software development are challenging. With increasing complexity and reduction of development time, ensuring software quality is one of the foremost priorities of vehicle manufacturers. Software architecture plays an important role in ensuring quality by implementing design principles which enhance non-functional quality attributes of the automotive software. The extent to which a software architecture definition fulfills the quality requirements is not verified at early stages of development. As a consequence, design problems are transferred to later stages of development thereby causing rework of software artifacts. The paper focuses on a tool-based evaluation of non-functional quality characteristics using the concept of Continuous Integration for AUTOSAR-based transmission control software. The suggested approach enables early and continuous evaluation of software architecture thereby improving software quality
