UN R102 — Supplement 1 to the 00 series of amendments

New paragraph 0. adds an Introduction to the Regulation. Paragraph 0.1. says that Supplement 1 to the original version is introduced to take into account vehicles of categories X and Y. It is also introduced to take into account vehicles with an Automated Driving System (ADS) and a manual mode operating at speeds above 6 km/h. Before this supplement, the Regulation had no paragraph 0.

Paragraph 0.1.1. says that the UN Regulation was originally drafted for vehicles with a driver and manual driving controls. The amendment intends to keep the spirit of the UN Regulation. It also intends to extend its application to vehicles without a driver and without manual driving controls inside the vehicle. In a vehicle without “driver/manual driving controls”, provisions related to them must not be taken into account, unless this amendment already covers them. Paragraph 0.1.2. says that, for vehicles with an ADS, no special provisions or exemptions apply in a manual driving mode. In a mode where an ADS feature is active, the relevant ADS requirements apply.

In paragraph 5.1.5.2., if the vehicle has an ADS, a logic signal must now go to the ADS for any power or control system failure. The acoustic and optical signals to the driver stay as before. While an ADS feature is active, a logic signal must tell the ADS about correct engagement of the positive locking system (para. 5.1.11.). Paragraph 5.1.13. covers hydraulic or pneumatic CCDs. While an ADS feature is active, it now requires a logic signal to tell the ADS that the CCD is about to reach maximum extension. In paragraph 5.1.11., a remote indication must now be installed in the “cabin”, not in the “driver's cabin”.

The control unit must now be fitted outside the “cabin”, not outside the “driver's cabin” (para. 5.1.7.2.). Paragraphs 13.3.1. and 13.3.2. now end with “(if applicable)”. They cover the acoustic device in the driver's cabin and the red optical signal on the instrument panel. The other words of these paragraphs stay the same.

The simulated overtaking manoeuvre is now conducted at a speed up to 80 km/h, or the maximum design speed, whichever is lower. Before, the speed went up to 80 km/h. The manoeuvre must not cause any difficulty in controlling the combination, and the words “the driver” are deleted. The steering test at 20 km/h has a new option while an ADS feature is active. In that case, the steering equipment is actuated at the maximum performance allowed by the ADS. No contact between the vehicles or damage to the CCD must occur.

In paragraphs 2.2.1., 2.2.3. and 3.1., the words “by the driver” or “the driver” are deleted. For example, paragraph 2.2.1. now ends with “without unusual steering correction”. Units now have a space, and some are written in words, for example “3.5 metres” and “10 per cent”. The test speeds, decelerations, accelerations and lane width stay the same.

Paragraph 1.1. now says “This UN Regulation applies to vehicles of categories N2, N3, O3 and O4”. Before, it said “This Regulation” and “Categories”, and the vehicle categories stay the same. A new footnote refers to the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8. In the text that GRSG sent to WP.29, the footnote said “Rev.8, para. 2”. AC.1 adopted ECE/TRANS/WP.29/2026/116 as amended by Annex VI of ECE/TRANS/WP.29/1192, which gives the footnote without “para. 2”.
