AUTOSAR Framework: Enabling Scalable and Modular Software Architecture in Contemporary Automotive Systems

Abstract

AUTOSAR (Automotive Open System Architecture) has emerged as a fundamental framework transforming automotive software development through a standardized, modular architecture that decouples hardware dependencies from software implementation. The framework enables seamless collaboration between original equipment manufacturers, suppliers, and developers by providing reusable software components across multiple electronic control units and vehicle platforms. AUTOSAR's Basic Software modules facilitate real-time diagnostics, fault detection, and robust system performance while supporting integration of complex infotainment systems with critical vehicle functions, including navigation, climate control, and advanced driver assistance systems. The evolution from Classic to Adaptive AUTOSAR platform addresses contemporary automotive requirements for high-performance computing, over-the-air updates, and real-time data processing essential for connected and autonomous vehicles. This standardization significantly reduces development costs and timeframes while maintaining consistency across diverse vehicle lines and manufacturers. AUTOSAR's modular design principles support the automotive industry's transition toward software-defined platforms, enabling flexible system architectures that accommodate rapidly evolving technological demands. The framework's contribution to automotive innovation extends beyond current applications, positioning the industry for future mobility solutions that require sophisticated software integration and seamless component interoperability across increasingly complex vehicular systems.
