Optimization of Automotive Matrix Headlamp Control for Enhanced Visibility and Glare Reduction Using HILS Validation

This study focuses on optimizing the control system of automotive matrix headlamps to enhance nighttime driver visibility while minimizing glare for other road users, including oncoming drivers and pedestrians. The research emphasizes the importance of precise and responsive high-resolution beam management to improve visibility and road safety. Using a developed simulator, we analyzed the impact of system delays—such as image processing, control processing, and communication delays—on headlamp performance. Strategies for optimizing beam control margins were proposed to maximize visibility and reduce glare, even with system speed constraints. Leveraging advancements in camera technology, the system enables adaptive beam adjustments based on detected objects, enhancing control accuracy. The proposed system’s effectiveness was validated through simulations and will be further tested using Hardware-in-the-Loop Simulation (HILS) for real-world applications.
