Multi-Agent LLM workflow for Regulatory-Driven Requirement Generation in Automotive Software Development

The increasing regulatory complexity in automotive development places significant pressure on engineering teams to derive complete and correct requirements. This paper presents a multi-agent-based large language model (LLM) workflow designed to support requirement extraction from technical specifications and regulatory documents in compliance with automotive requirement guidelines. The approach structures the requirement derivation process across collaborating agents that interpret specification and regulatory text, generate candidate requirements for the early engineering activities, and cross-validate their outputs to improve consistency and traceability. To evaluate the applicability of the workflow in an industrial context, we applied it to the draft Euro 7 emissions regulation. The agents produced requirements for relevant functional domains, which were subsequently reviewed by domain experts at FEV. The evaluation focused on correctness, completeness, and coverage. Results indicate that the agentic workflow can achieve high alignment with expert expectations, demonstrates robust coverage of regulatory intent, and reduces manual effort in the early requirements engineering phase. The findings highlight the potential of structured multi-agent LLM systems to accelerate compliant software development processes and to enhance the reproducibility and quality of regulatory requirement interpretation in the automotive domain.
