Modified version of document GRRF/2011/35/Rev.1, pursuant to GRRF session 72 discussions, which aims to clarify reasonable levels of braking performance to be expected in different positions of the ignition key (i.e., off, on, lock, etc.).

CLEPA and OICA proposal to harmonize Regulations Nos. 13 and 13-H with the Federal Motor Vehicle Safety Standard FMVSS 135 on electric vehicle requirements with regard to the regenerative braking system (RBS).

Working paper proposing to revise the transitional provisions of UN R13-H based on a review undertaken pursuant to the discussions at the last GRRF session.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) in order to introduce the concept of “revision of approvals” into regulations under GRRF responsibility.

Several vehicle control regulations refer to compliance with UN Regulation No. 10 on electromagnetic compatibility. The proposal would revise these references to focus only on the technical (thus excluding administrative) requirements since some countries do not apply UN R10.

Proposal for collective amendments of amendments to Regulations Nos. 13 (Heavy vehicle braking), 13-H (Brakes of M1 and N1 vehicles), 79 (Steering equipment) and 89 (Speed limitation devices) and the new Regulations on LDWS and AEBS to clarify the references to Regulation No. 10 into the UN Regulations mentioned above.

Text prepared by the International Organization of Motor Vehicle Manufacturers (OICA) to introduce the concept of “revision of approvals” into the UN Regulations under GRRF responsibility in order to align the UN Regulations with the EU Whole Vehicle Type Approval Directive 2007/46/EC in order to ease the administrative burden for both manufacturers and approval administrations regarding the extension of existing approvals.

Proposal to transfer brake assist systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval.

Proposal to transfer electronic stability control systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval.

Proposal to delete references to electronic control systems and brake assist systems within UN R13-H in order to simplify use of the regulation within the proposed international whole vehicle type approval regulation. These provisions would be taken up by new separate UN Regulations.

Proposal to transfer electronic stability control systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-15.

Proposal to transfer brake assist system systems provisions out of UN Regulation 13-H and into a new stand-alone regulation. The proposal arises from a perceived need to simplify UN R13-H to facilitate its application within the proposed international whole vehicle type approval. This document supersedes document GRRF-75-14.

Proposal for amendments to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations.

Proposed amendments to UN R13-H to confirm that the complex electronic control system (CEL) requirements may be satisfied through an approval conducted under another regulation (e.g., the pending new ESC and BAS regulations) and to delete the marking requirement concerning ESC systems which will no longer be within the scope of UN R13-H.

Explanation of three options developed for handling the approval of electronic stability controls (ESC) and brake-assist systems (BAS) under regulaitons separate from UN R13-H (light vehicle braking) while fulfilling the requirements of complex electronic systems (CEL).

New proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.

New proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.

Updated proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations. This proposal supersedes document GRRF/2014/10.

New revised proposal to delete provisions for electronic stability and brake-assist systems from UN R13-H as part of their transposition into new stand-alone regulations.

Proposed new stand-alone UN Regulation comprised of the brake assist systems provisions of UN Regulation 13-H.

Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.

Proposal to amend provisions on electronic stability control warnings under braking regulations to allow for activation of the ESC visual warning during a stability-assistance intervention of an electronic steering control. The aim is to avoid separate requirements for brake-actuated and steering-actuated stability assistance that would lead to two visual warnings where only one is appropriate.

Revised proposal pursuant to GRRF discussions to enable activation of the ESC optical symbol in cases of a corrective steering function intervention when the CSF intervention is activated under the control of an ESC system. The aim is to avoid separate requirements for brake-actuated and steering-actuated vehicle stability functions (VSF) that would lead to two optical warnings where only one is necessary. This would enable use of the ESC intervention tell-tale for CSF steering intervention.

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 for amendments to the draft proposal concerning changes to the provisions introduced by the 02 series of amendments for remote-controlled parking (RCP).

Proposal to improve the uniformity of requirements for stop lamp illumination with regard to various types of braking systems, including those of electric vehicles.

Presentation regarding requirements for stop lamp illumination with regard to various types of braking systems, including those of electric vehicles.

Proposal to amend Supplement 3 to the 01 series of amendments to clarify the conditions under which the braking signal for vehicles equipped with automatically commanded braking and/or regenerative braking is to be generated.

Proposal to clarify the different interpretation from Authorities and Technical Services on how the requirements of paragraph 5.2.22.2. are to be understood with regard to the conditions under which the signal is still to be generated.

Proposal to allow a mechanical locking device as an alternative to the friction parking braking to hold the vehicle.

Proposal to permit the use of a positive lock type system as an alternative to a friction type parking brake system.

Proposal to amend the proposal to permit the use of a positive lock type system as an alternative to a friction type parking braking system.

Proposal to enable the type approval of a park lock device as an alternative to the friction parking braking to hold the vehicle.

Proposal to permit the type approval of a park lock device as an alternative to the friction parking brake(s).

Proposal to enable the type approval of a park lock device as an alternative to or in combination with the friction parking braking to hold the vehicle.

Proposal to amend provisions in documents GRVA/2025/13 and GRVA/2025/14 concerning the type approval of a park lock device as an alternative to or in combination with the friction parking braking.

Proposal to clarify that an Emergency Stop Signal may be generated by application of the service braking system via the Electronic Parking Brake.

Proposal to clarify that the Emergency Stop Signal (ESS) may be generated by application of the service braking system via the Electronic Parking Brake (EPB) control.

Proposal to clarify that only one braking control (e.g., service braking control, parking brake control) shall be used for each test condition of the secondary braking effectiveness and to permit the selection of the braking control based on the vehicle load condition.

Proposal from OICA, CLEPA, and CITA to amend CITA’s proposal to enable real-time reading of electrical transmission brake demand values via an electronic vehicle interface and an off-board electronic device during periodical technical inspections, including a 24-month transitional period.
