Proposal from the task force on Automated Vehicle Categorisation (AVC) to amend the Resolution on vehicle construction for application to ADS vehicles, including the introduction of new vehicle subcategories X and Y.

Proposal to amend UN R73 on Lateral Protection Devices, amending ECE/TRANS/WP.29/GRSG/2024/38. The proposal adds safety requirements including a new definition of Blind Spot Information System referencing UN R151. Key modifications lower the minimum height of the lower edge of LPD from 550 mm to 450 mm for most vehicles, while maintaining 550 mm for vehicles with axle distance exceeding 6.5 m. The proposal includes transitional provisions and references GRSG-113-13. Japan and France submitted this based on traffic accident data showing reduced fatalities with lower LPD height requirements.

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure (per the updates and transfer of device specifications from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1)).

Proposal to update the references to the three-dimensional H-point (3-D “H”-point) measurement and calibration procedure pursuant to the update of the device specifications and transfer from the Consolidated Resolution on the Construction of Vehicles (R.E.3) to Mutual Resolution No. 1 (M.R.1).

Notification specifying the details of safety standards for road transport vehicles with regard to rear vision monitor devices auto-translated from original Japanese text.

The Task Force reviewed the effectiveness of UN R151, R158, and R159 in reducing accidents and examined new or enhanced technologies and detection ranges. Regarding accident reduction effectiveness, the Task Force consensus was that it is too soon for quantitative review as vehicles equipped with compliant systems are still limited, though qualitative approaches surveying drivers and operators of compliant vehicles remain possible. On detection ranges, UN R151 currently allows a 900mm no detection zone to the side of the vehicle and UN R159 allows an 800mm no detection zone to the front. The Task Force recommended reviewing actual detection performance of vehicles and exploring whether the non-detection zones can be reduced using new technologies such as dual RADAR sensors.
