Text prepared by the Italy to modify provisions concerning the sharing of components within combined braking systems (CBS) in order to adapt to technological progress.

Series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements.

Request for authorization to develop an amendment to the GTR on motorcycle braking systems to clarify the terms “inoperative” and “disconnected”, refine the definition of combined braking systems (CBS) in line with technological advances, and to make editorial improvements.

Corrections to the proposed series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements.

The proposed amendments would:

a) clarify possible confusion in the interpretation of the terms “inoperative” and “disconnected”;
b) update requirements for combined braking systems;
c) introduce the “K-method”; and
d) introduce the concept of a representative vehicle based on the
provisions of Regulation No. 13-H.

Proposal from Italy to clarify provisions concerning the use of Combined Braking Systems (CBS) in GTR No. 3.

Updated proposal for a series of amendments to clarify a variety of requirements, notably concerning test surface requirements, ABS cycling, and peak braking coefficient measurements. The proposal clarifies the terms “inoperative” and “disconnected”, introduces the “K-method” and the use of a representative vehicle based on UN R13-H.

Proposal to clarify the intent of the selected paragraphs to ensure that systems with with one service brake meet braking performance requirements using only that brake system (i.e, without any assistance from the secondary brake system). There had been an interpretation that for systems with two service brakes each brake had to meet the requirements which would result in higher stringency levels than intended by the requirement for single brake systems.

The proposal also clarifies the parts of the braking system that should be considered with respect to hydraulic brake and mechanical transmissions and further clarifies that the test procedures are designed to simulate a brake failure rather than produce one.

Request for authorization to develop amendments to GTR No. 3 in order to:

1. align GTR 3 with Supplement 3 to the 03 series of amendments to UN Regulation No. 78 adopted at June 169/WP.29 (electromagnetic compatibility requirements for ABS, application of ABS provisions to three-wheelers, installation of emergency stop signal) and
2. clarify the possibility to install a means to disable the ABS function (‘ABS Switch’) under certain conditions.

Proposal to develop an amendment in order to align GTR No. 3 with technical progress, addressing among others: ensuring electromagnetic immunity of ABS-systems, introducing ABS performance requirements for category 3-5 vehicles (three-wheelers), ensuring uniform requirements for equipment such as Electronic Stop Signal System and the means to disable the ABS, if equipped. This amendment aims to harmonize GTR with recent amendments made to UN Regulation No. 78.

Proposal introducing provisions for the activation of the stop lamp under regenerative braking and updating the references to ASTM standards to enable the use of the new ASTM standard reference test tyre F2493 for the measurement of the Peak Braking Coefficient (PBC).

Proposal from Italy with support from IMMA to adapt GTR No. 3 to technical and standardization progress, introducing provisions for the activation of the stop lamp under regenerative and/or automatically commanded braking, and updating the references to ASTM standards to enable the use of the new ASTM standard reference test tyre F2493 for the measurement of the Peak Braking Coefficient (PBC).
