Human-Centric Automotive Interior Lighting assessment: A feedback-Based Approach

Automotive interior lighting systems must comply with rigorous internal standards while aligning with evolving customer expectations across diverse vehicle segments. As technological advancements accelerate and consumer demands grow, these systems have become increasingly advanced. Traditionally, validation relied on physical integration with vehicle and its hardware particularly silver box unit and infotainment systems. However, this conventional approach presents several limitations, including dependency on mature hardware and software, challenges in testing and synchronization across multiple lighting modules, and constraints in design validation accuracy. To address these limitations, this paper introduces an innovative approach that employs real-time hardware-in-the-loop (HIL) simulation for digital lamp testing. This method facilitates autonomous and abuse testing, enabling independent validation of interior lighting systems within a controlled virtual environment while eliminating the dependency on physical vehicle integration. By digitally controlling lighting systems, this approach provides several key advantages, including accelerated testing cycles, early-stage design validation, integration testing and delivers higher validation accuracy through precise simulation of real-world scenarios. Additionally, the approach establishes an effective closed loop feedback mechanism for faster issue identification, contributing to significant reduction in overall testing time. This paper outlines the methodology for implementing digital simulation through HIL technology, effectively mitigating the shortcomings of conventional testing frameworks
