UN Regulation No. 157 — 01 series

1.1; selected definitions in 2; 5.2.6 · 2023-01-04

Séria 01 rozširuje rozsah na kategórie M a N a v definícii ALKS uvádza rýchlosť 130 km/h or nižšiu. Bod 5.2.6 stanovuje požiadavky na systémy schopné meniť jazdný pruh.

Čítať spolu s ostatnými zmenami série 01. Dátum vstupu zmeny do platnosti sám neurčuje použiteľnosť na konkrétne vozidlo or jeho prevádzku.

English explanation

The 01 series extends scope to categories M and N and defines ALKS for travelling speeds of 130 km/h or less. Paragraph 5.2.6 sets requirements for systems capable of lane changes.

Read with the other amendments to the 01 series. Entry into force alone does not determine applicability to a particular vehicle or its operation.

UN Regulation No. 157 — Supplement 1 to 01 series

2.27; 8.2.1–8.2.3 · 2023-09-24

Doplnok 1 mení bod 2.27 na prerušený manéver zmeny jazdného pruhu (LCM), nie celý postup (LCP). Rozširuje zaznamenávanie udalostí DSSAD a spresňuje časové okná ich uchovávania.

Čítať spolu s ostatnými zmenami série 01. Dátum vstupu zmeny do platnosti sám neurčuje použiteľnosť na konkrétne vozidlo or jeho prevádzku.

English explanation

Supplement 1 revises paragraph 2.27 to refer to an aborted lane change manoeuvre (LCM), rather than the entire procedure (LCP). It extends DSSAD occurrences and specifies recording time windows.

Read with the other amendments to the 01 series. Entry into force alone does not determine applicability to a particular vehicle or its operation.

UN Regulation No. 157 — Supplement 2 to 01 series

5.1.7 · 2024-06-15

Doplnok 2 odkazuje v bode 5.1.7 na technické požiadavky a prechodné ustanovenia série 06 or neskoršej UN R10. Tento odkaz neskôr nahradil doplnok 3.

Čítať spolu s ostatnými zmenami série 01. Dátum vstupu zmeny do platnosti sám neurčuje použiteľnosť na konkrétne vozidlo or jeho prevádzku.

English explanation

Supplement 2 makes paragraph 5.1.7 refer to the technical requirements and transitional provisions of the 06 or later series of UN R10. Supplement 3 subsequently replaces this reference.

Read with the other amendments to the 01 series. Entry into force alone does not determine applicability to a particular vehicle or its operation.

UN Regulation No. 157 — Supplement 3 to 01 series

5.1.7 · 2025-06-12

Doplnok 3 nahrádza bod 5.1.7 odkazom na technické požiadavky a prechodné ustanovenia série 07 or neskoršej UN R10. Definitions v oddiele 2 nemení.

Čítať spolu s ostatnými zmenami série 01. Dátum vstupu zmeny do platnosti sám neurčuje použiteľnosť na konkrétne vozidlo or jeho prevádzku.

English explanation

Supplement 3 replaces paragraph 5.1.7 with a reference to the technical requirements and transitional provisions of the 07 or later series of UN R10. It does not amend section 2 definitions.

Read with the other amendments to the 01 series. Entry into force alone does not determine applicability to a particular vehicle or its operation.

UN Regulation No. 157 — Supplement 6 to 00 series — amendment text

5.5.5; 6.2.2; footnote 3 · 2026-01-11

Doplnok 6 k sérii 00 upravuje opätovnú aktiváciu ALKS po manévri minimálneho rizika a predvolený vypnutý stav pri spustení pohonného systému. Automatický opätovný štart, napríklad stop/start, sa na tento účel nepovažuje za nové spustenie pohonného systému.

Poznámka odkazuje na M.R.2, ECE/TRANS/WP.29/1121. Tento doplnok neobsahuje zmenu definícií v oddiele 2.

English explanation

Supplement 6 to the 00 series revises ALKS reactivation after a minimum risk manoeuvre and its default off mode at initiation of the powertrain. An automatic restart, such as stop/start, does not count as a new initiation of the powertrain for this purpose.

The footnote refers to M.R.2, ECE/TRANS/WP.29/1121. This supplement contains no amendment to section 2 definitions.

Text OSN / UN text ↗ · PDF (EN) · C.N.45.2026 — vstup do platnosti / entry into force ↗

UN Regulation No. 157 — Supplement 4 to 01 series — amendment text

5.2.6.5.1(d); 5.5.5; 6.2.2; footnote 4 · 2026-01-11

Doplnok 4 k sérii 01 pridáva podmienku pravidelnej zmeny jazdného pruhu pre vozidlá N3 a M3: cieľový pruh musí mať povolenú maximálnu rýchlosť obmedzenú pre všetky kategórie vozidiel. Zároveň upravuje opätovnú aktiváciu po MRM a vypnutý stav pri spustení pohonného systému vrátane výnimky pre automatický stop/start.

Ide o doplnok série 01, nie o úplné znenie ALKS. Nemožno ním samostatne preukázať všetky podmienky zmeny pruhu or rozsah série 01.

English explanation

Supplement 4 to the 01 series adds a condition for regular lane changes by N3 and M3 vehicles: the target lane must have a permitted maximum speed limited for all vehicle categories. It also revises reactivation after MRM and default off mode at powertrain initiation, including the automatic stop/start exception.

This is a supplement to the 01 series, not the full ALKS text. It does not on its own establish every lane-change condition or the scope of the 01 series.
