Proposal to introduce provisions for electric regenerative braking systems.

Proposal to require a vehicle stability function on vehicles with four axles commercial vehicles over 25 tons in light of their specific use.

At the 13th session of GRVA the UK presented an informal document (GRVA-13-19) with the purpose of starting discussion on the content of UN Regulation 13, Annex 18. The proposal was made in recognition of the inconsistent understanding of the current text, identified during the discussions leading to the 03 series of amendments to UN R79 which shared common language. It is intended that using harmonised text between Regulations, as far as is practicable, will deliver more consistent application of the requirements and avoid unnecessary changes in procedures and documentation for different vehicle systems.

Proposal to introduce provisions for electric regenerative braking systems.

Proposal to introduce requirements to enable the type approval of Electro-Mechanical Braking (EMB) systems.

Proposal to clarify provisions regarding the actuation of the parking brake warning device to cover the case of electric control transmission systems where there may be a transition between parked (applied) and un-parked (released) braking states.

Proposal to ensure that N₃ category four-axle chassis, regardless of bodywork in second stage production (e.g., concrete mixer), will be included within the scope of the vehicle stability provisions.

Proposal to align the requirements of UN R13 concerning the assessment of electronic control systems with the latest developments adopted by WP.29 for UN R79 and UN R157.

Proposal to introduce provisions for the approval of electromechanical braking systems.

Test prepared by the experts of the Informal Working Group (IWG) on hydrogen and fuel cell vehicles (HFCV), UN Global Technical Regulation No. 13, Phase 2 (GTR13-PH2) and proposes enhancement of the global harmonisation of the technical requirements of compressed hydrogen storage systems and vehicles equipped with them.

Proposal to resolve problems with installation of stronger spring brake actuators in trailers to realize higher deceleration in the case of emergency braking caused by a cut of the supply line between towing vehicle and trailer.

Proposal from GRVA to resolve problems with installation of stronger spring brake actuators in trailers to realize higher deceleration in the case of emergency braking caused by a cut of the supply line between towing vehicle and trailer.

Proposal to equip four-axle commercial vehicles over 25 tons with vehicle stability function due to their specific use.

Supporting information on the proposal to allow for parking brake warning device actuation after an electric control transmission system produces a stable parked state.
