Glare-Free High Beam (GFHB)

16.1. Why the Glare-Free High Beam? To make a new step up in road illumination performance, the lighting system had to overcome the following points: l The high beam in its original definition glares oncoming traffic in many situations and cannot be used permanently in its current format. l As a general rule, drivers have a reluctance to operate the main beam and are used to frequently switch back from high to low beam too early. l The separation distance between vehicles implies that the low beam cannot provide an optimized forward illumination in most of the driving circumstances.

The Glare-Free High Beam (GFHB) also known as Adaptive Driving Beam (ADB) is the next evolution of the Full Adaptive Front Lighting (AFS) system. Definition according to ECE R48 rev.9: “Adaptive main-beam” relates to a main-beam of the AFS that adapts its beam pattern to the presence of oncoming and preceding vehicles in order to improve the long-range visibility for the driver without causing discomfort, distraction or glare to other road users.
