This Regulation establishes uniform provisions for crashworthiness approval of N1Y vehicles regarding fuel system integrity, electrical shock protection, and crash compatibility during frontal, rear, and lateral collisions. The provisions for frontal impact are based on UN R94 or UN R137 per manufacturer choice with Technical Service agreement; lateral impact provisions are based on UN R95; rear impact provisions are based on UN R153. Vehicles with maximum design speeds not exceeding applicable impact speeds shall be tested at their maximum design speed and comply with post-impact requirements. Crash Compatibility Criterion shall not exceed 40–45 g and Crash Compatibility Value shall not exceed 100–120 g×tonne. For vehicles derived from types already approved under UN R94, UN R137, UN R95, or UN R153, previous test results may be used if mass increases do not exceed 8 per cent.
Proposal, updated with in session comments, to amend Footnote 1 to reference document ECE/TRANS/WP.29/78/Rev.8, amend para. 6.1.5. to clarify that the exemption for sensors being part of driver assistance systems does not apply to automated driving systems, remove non-exhaustive examples of sensors, replace “disoriented” with “misaligned”, and align terminology to “driver assistance systems”. The exemption for driver assistance systems is retained because their failure does not prevent manual vehicle operation, whereas automated driving systems’ perception equipment forms part of the driving function, and damage to sensing devices may prevent vehicle operation contrary to Regulation No. 42’s objective.
Updated document with in-session comments.
Draft text for a new UN Regulation on crashworthiness of vehicles of category N1Y, including comments from France:
Proposal for a task force to conduct discussions for drafting the regulation to incorporate the Euro 4-level requirements of UN GTR No. 2 into UN R40. Malaysia and Japan will serve as co-chairs. The Task Force shall review the Euro 4 level requirements and any relevant provisions of UN GTR No. 2 and assess their suitability for transposition into UN R40 under the 1958 Agreement framework. The Task Force shall develop draft regulatory text covering test procedures and test conditions, pollutant limit values and related technical parameters, reference fuels and associated testing requirements, administrative and type approval provisions, and transitional provisions and entry-into-force considerations. Target for submission of informal document for draft UN R40-03 is 96th GRPE scheduled in April 2027.
