UN R85 — Supplement 14 to the 00 series of amendments
Supplement 13 → 14
- What changed
- In Annex 6, paragraph 2.5.1., the net power test now uses maximum acceleration demand instead of the accelerator control set at the maximum position.
- In footnotes 1 and 2, the reference to R.E.3 is now to document ECE/TRANS/WP.29/78/Rev.8.
- Why
- The proposal introduces changes that are necessary to include vehicles with Automated Driving Systems in the existing Regulation.
- The references to R.E.3 are updated to include vehicles equipped with an ADS in the scope.
Q1What changed3 changes
Acceleration demand in the net power test (Annex 6, para. 2.5.1.)
The test for determining the net power must be carried out with maximum acceleration demand. Before this supplement, the test had to be carried out with the accelerator control set at the maximum position. AC.1 adopted ECE/TRANS/WP.29/2026/149 as amended by Annex VI of ECE/TRANS/WP.29/1192. Annex VI contains this change to Annex 6, paragraph 2.5.1.
References to R.E.3 in footnotes 1 and 2 (paras. 1.1. and 4.5.1.)
Footnote 1 to paragraph 1.1. refers to the Consolidated Resolution on the Construction of Vehicles (R.E.3.) and now gives document ECE/TRANS/WP.29/78/Rev.8. Before this supplement, it gave paragraph 2 of document ECE/TRANS/WP.29/78/Rev.2. Footnote 2 to paragraph 4.5.1. refers to Annex 3 to R.E.3 and now gives document ECE/TRANS/WP.29/78/Rev.8. Before this supplement, it gave document ECE/TRANS/WP.29/78/Rev.2/Amend.3. Both footnotes now give the address https://unece.org/transport/vehicle-regulations/wp29/resolutions.
