Request for input regarding relaunch of the Modular Vehicle Combinations informal group whose work was interrupted due to prioritization of work on Automatically Commanded Steering Systems (ACSF).

Discussion presentation for adapting UN R13 to electric vehicle systems with regard to the required state of charge of the vehicle battery under downhill and endurance braking test procedures.

The 02 series of amendments to UN R79 introduced requirements for RCP systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot.

Revision 7 of Regulation No. 13 includes a former version of Figure 1B which was changed with Amend 4 to Revision 6 of UN Regulation No. 13. This correction is also needed for Revision 8, which contains the same error.

Revised proposal concerning remote-controlled parking (RCP). The new series 02 of Regulation 79 introduced requirements for RCP systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot. The second proposal in the original document concerning regenerative braking and stop lamp activation will be discussed again as a revised formal document at the September 2018 GRRF session.

This document presents two proposals. (1)The new series 02 of Regulation 79 introduced requirements for RCP (remote controlled parking) systems. An RCP system requires the engagement of an EPB (electronic parking brake) once the manoeuvre has finished and the ignition is switched off. This proposal would allow the release or disconnection of the EPB by a remote control system (approved to R79) so the RCP can subsequently drive the vehicle out of a parking spot. (2) Proposal to permit illumination of the stop lamp for electric regenerative braking under 0.7m/s² deceleration in order to allow for “one-pedal driving” of electric vehicles.

Proposal to

1. delete redundant provisions (paragraphs 2.2. and 2.2.1.) in favor of paragraph 5.2.2.13. which requires all O4 trailers to be equipped with Anti-lock Braking Systems (ABS) of Category A.
2. clarify exemptions from electronic stability control requirements, and
3. enable the verification of sufficient movement of the balancer without having to take measurements underneath the trailer.
