Summary of GRBP-74-06

20. GRBP noted GRBP-74-06 and GRBP-74-34 and invited the expert from France to submit these proposals to the next session in the form of an official document.

Proposal regarding the ALKS forward detection range within the context of raising the specified maximum speed of ALKS up to 130 km/h.

Proposal to add requirement on the monitoring of the machine deviation for rolling resistance measurement.

24. GRBP considered GRBP-74-04 and invited the expert from France to liaise with the experts from ETRTO with the aim to prepare a working document for the next session.

The purpose is to ensure that the target test speed is either 10 km/h, or 20 km/h, in forward motion, or 6 km/h in reverse motion and that the tolerances given by the regulation are linked to the testing and not used for more favorable testing speed.

12. The expert from France introduced a proposal that aimed to clarify the interpretation of the requirements concerning the variation of the sound emitted proportionally with the vehicle speed (ECE/TRANS/WP.29/GRBP/2021/14). She also proposed to clarify the testing requirements (GRBP-74-05). GRBP supported in principle these proposals, subject to replacement in GRBP-74-05, paragraph 6.2.3.2. of “≥” with “greater or equal to”, but in view of other ongoing activities on UN Regulation No. 138 decided to await further amendment proposals with the aim to combine them into a single package before submitting to WP.29 and AC.1.
