Argument for revising the PBC values used in the regulation based on technological progress in tyres and impact on road-friction parameters.

Proposal to amend the peak braking coefficient and related test method provisions.

Proposal to clarify AEBS restart, including that an automatic engine restart (stop/start systems) does not require a reactivation of the AEBS, to allow for electromagnetic compatibility demonstration via the 06 series of amendments to UN R10, to move provisions for Indication of an ongoing initialization from the section on failure indications to a separate paragraph, and to make an editorial correction.

Proposal to amend provisions related to the AEBS peak braking coefficient.

Proposal to align the wording with regard to “dry road affording good adhesion” across the series to avoid confusion with use of “dry road” under different contexts by other regulations.

Proposal to clarify the interpretation of “engine start/run cycle”.

Proposal to clarify that the AEBS may be automatically deactivated in the event that the electronic stability control system is deactivated.

The proposal is to ensure that the adhesion of the road surface will not limit AEBS performance during test.

Proposes to align the wording with regard to “dry road affording good adhesion” also in the 02 series of amendments with the purpose of avoiding confusion with other regulations that might refer to a “dry road” in a different context

Proposed changes to align RxSWIN provisions with the RxSWIN template adopted through WP.29-197-06, remove the proposed requirement to comply with UN R156/01 or later from R157 and R171, remove amendments to UN R155 as decided by the IWG CS/OTA, apply the RxSWIN amendments also to earlier series of amendments in R13, R13-H, R79, R131, R152, R157, and R171, update references to the latest version of R.E.3, ECE/TRANS/WP.29/78/Rev.8, in earlier series, and correct paragraph references and improve structure in R89, R139, R140, R155, R156, and R171.
