Abstract:
The rapid evolution of automotive electronics, autonomous driving technologies, electrification, and software-defined vehicle architectures has significantly increased the complexity of automotive embedded systems. This transformation has intensified the need for robust process governance, safety assurance, and systematic engineering practices capable of addressing stringent regulatory and quality requirements. Automotive SPICE (ASPICE) and ISO 26262 have emerged as two dominant frameworks within the automotive industry. ASPICE primarily focuses on process capability assessment and software process improvement, whereas ISO 26262 emphasizes functional safety lifecycle management for electrical and electronic systems in road vehicles. Despite their widespread adoption, organizations frequently encounter substantial implementation challenges due to overlapping activities, duplicated documentation, fragmented workflows, inconsistent traceability, and increased compliance costs resulting from independent implementation of both standards. This research proposes an ASPICE-based Unified Process Improvement Framework (UPIF) for achieving efficient ISO 26262 functional safety compliance in automotive systems. The proposed framework integrates ASPICE process areas with ISO 26262 safety lifecycle activities through a harmonized systems engineering approach. The study systematically analyzes existing literature, industrial practices, safety engineering methodologies, and process capability models to identify integration gaps and develop a structured unified model. The framework establishes process alignment among system engineering, software engineering, hardware engineering, verification and validation, risk management, configuration management, and safety assurance activities. The research further evaluates the proposed framework using comparative analysis involving traditional separated implementation models and integrated process architectures. The results demonstrate that the unified framework significantly improves traceability, process consistency, development efficiency, audit readiness, defect prevention, and safety evidence management. Additionally, the framework supports agile and model-based development practices while preserving compliance integrity. The study contributes both theoretically and practically to automotive process engineering by introducing a scalable integration methodology suitable for advanced driver assistance systems (ADAS), autonomous vehicles, electric vehicle platforms, and safety-critical embedded systems. The findings indicate that organizations adopting integrated ASPICE-ISO 26262 process architectures can reduce process redundancy, improve safety culture, accelerate product releases, and enhance overall software and system quality. The proposed framework therefore provides a strategic foundation for next-generation automotive development ecosystems where functional safety, cybersecurity, software quality, and continuous process improvement must coexist seamlessly.
