UN R13-H: Proposal for a Supplement to the 02 series of amendments

Source(s)

Date

3 Jul 2026

Status

GR approved as amended

Subject

UN R13-H Light Vehicle Braking

Impact

02 series of amendments | Supplement 3

Meeting(s)

GRVA | Session 26 | 14-18 Sep

Agenda item 8. (c) Clarifications

Proposal to amend Annex 8, para. 3.4.1. to require that the strategy chosen shall not prejudice safe operation of the system due to failures with other systems involved in achieving the function of the system, and amend Annex 8, para. 3.4.4. to require that analysis of system behaviour on fault occurrence includes faults with other systems involved in achieving the function of the system, and to correct ‘safetys’ to ‘safety’. The proposal addresses a collision where tyre failure resulted in unsafe ABS activation. Although the 02 series clarified ABS as part of electronic control systems assessment, it does not explicitly state what is covered, potentially missing relevant faults or failures influencing system function. The additions ensure all relevant faults or failures are accounted for in manufacturers’ safety concept and analysis.

67. The representative of the United Kingdom introduced document ECE/TRANS/WP.29/GRVA/2026/36, proposing amendments to UN Regulation No. 13-H aimed at addressing the issue presented in informal document GRVA-25-42 at the previous session. GRVA inquired whether a similar issue could also arise for vehicles covered by UN Regulation No. 13 and agreed to resume discussion of this matter at its next session. The representative of CLEPA presented an alternative proposal contained in GRVA-26-24. Following discussion, GRVA reviewed informal document GRVA-26-32.

68. GRVA adopted ECE/TRANS/WP.29/GRVA/2026/36, as amended by Annex XI to this report (based on GRVA-26-32), and requested the secretariat to submit it as draft Supplement 3 to the 02 series of amendments to UN Regulation No. 13-H to WP.29 and AC.1 for consideration and vote at their March 2027 sessions.
