The Evaluation of AFS Beam Pattern using the Movement of the Driver’s Eye-Fixation Points
Since the Adapted Frontlighting System (AFS) was commercialized in 2003, it has helped improve visibility on curves. This paper reports that:
The driver’s eye-fixation points change for different areas on a curve. This was found by observing the driver’s gaze behavior in horizontal directions and the road geometry of curves; and
There is a correlation between the gaze behavior in horizontal directions and the headlamp lighting, AFS lighting in particular. This correlation was used to evaluate the AFS lighting performance.
