Integration Study of Vehicle Posture Sensors for Dynamic Control of HD Lighting

This study investigates the integration of vehicle posture sensors to enhance the dynamic control of automotive HD Lighting systems. With the increasing precision of HD-ADB and road communication technologies, minimizing pitch angle variations is essential or maintaining optimal beam orientation. Traditional posture estimation methods lack responsiveness and accuracy under dynamic conditions such as acceleration, bumps, or cornering. To address this, the study compares mechanical height sensors and electronic IMUs through real-vehicle experiments, analyzing their impact on beam stability, cut-off line control, and E-DBL performance. The findings aim to improve nighttime visibility and driving safety by optimizing sensor-based control of HD Lighting.
