This regulation proposes uniform provisions for the approval of electric powertrain retrofit systems (EPRS) intended for the conversion of vehicles of categories M and N to electric propulsion. It establishes requirements for EPRS design, installation by authorized installers, type approval procedures, application ranges, markings, conformity of production, and modification or extension of approvals. Specific requirements for compliance with applicable UN Regulations are defined, including electromagnetic compatibility, braking, power measurement, rechargeable energy storage systems, and mass and dimension limits. The regulation applies to both pure electric vehicles (EV) and hydrogen fuel cell vehicles (HFCV).
Proposal to clarify para. 5.6.4.6.8.1.(e) of UN R79 to address how different direction indicator lever mechanisms comply with manual deactivation requirements for automated lane change systems. The regulation currently does not distinguish between full-turn methods, where the lever returns to neutral position, and half-turn methods, where activation of the opposite direction indicator or stalk activation in the opposite direction constitutes deactivation. Two options are presented: either add separate provisions for each method, or note that activation of opposite direction indicator lamps may constitute deactivation of the initiating signal.
Proposal to:
Proposal to amend Article 2, paragraph 2 to clarify that where a Certificate of Compliance required under a UN Regulation and issued by an Approval Authority of another Contracting Party is accepted by a Contracting Party, the Approval Authority granting the corresponding type approval shall remain responsible for all aspects of that type approval. The amendment addresses management systems and their Certificates of Compliance used in UN Regulations such as UN R155 and UN R156.
Proposal for driver acknowledgement of correct use of DCAS.
