| HWT on ADB/AFS status report to TFGP |
| Reference Number: TFGP-08-02 |
|
The Homework Team on ADB/AFS status report to the GRE Taskforce “Glare prevention” documenting timeline activities from February to June 2026, including seven HWT meetings and three TFGP sessions. The team listed system descriptions, benefits, disadvantages, conducted literature review, identified elements causing glare, negative effects to ADB/AFS performance, and improvable requirements. The team drafted recommendations addressing enforcement of headlamp cleaning, reduction of 2000lm limit, manual override requirements, improved detection and camera specifications, motorway ADB usage, cleaning systems, beam pattern dimming, and adaptive beam patterns for various driving conditions. |
| Meeting Sessions: 8th TFGP session (9 Jun) |
| Document date: 03 Jun 26 |
| Relevant to: UN Regulation No. 149 | Road Illumination Devices (RID) and WP.29 Discussion Topic | Glare prevention |

The Homework Team on Adaptive Driving Beam/Adaptive Front-lighting Systems prepared a status report identifying elements causing glare in activated ADB/AFS systems, including wet road conditions, external objects obstructing sensors, soiled headlamps, camera positioning, and detection limitations. The report examined literature and expert inputs to determine negative performance effects and recommend improvements such as enhanced detection capabilities, stricter cleaning requirements, increased safety margins, predictive beam adjustment, mandatory motorway ADB usage, and driver instruction on manual override functions. Knowledge gaps and potential research needs were identified for consideration in draft recommendations to the Taskforce on Glare Prevention. |

Adaptive Driving Beam: A main beam of an 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.
Adaptive Front-lighting System: A lighting system providing beams with differing characteristics for automatic adaptation to varying conditions of use of the dipped-beam (passing-beam) and, if it applies, the main-beam (driving-beam)
Working Party on Lighting and Light-signalling Equipment (cf French: Groupe de Rapporteurs sur l’Eclairage)
Homework Team: A group of experts tasked with providing input for consideration by their parent group in a future meeting.
