TF-AVRS screened UN Regulations for automated vehicle application, focusing on UN R83 and UN R154. Changes enable automated driving system vehicles to perform driver-conducted tests like coast-down tests and roller bench cycles. Modifications include defining vehicle users as drivers or ADS users, adjusting driver mass calculations for X and Y categories, and updating testing mode terminology. TF-AVRS proposes amendments to 17 UN Regulations and seeks guidance on addressing remaining topics.

Proposal to amend UN Regulation No. 180 to incorporate vehicles with Automated Driving Systems. Modifications include adding ADS-related abbreviations and definitions, updating the excess exhaust emissions driver warning system to apply to ADS users, and revising monitoring parameters to account for torque demand from automated systems. Changes enable type approval of vehicles equipped with Automated Driving Systems.

Proposal to enable the approval of vehicles equipped with an Automated Driving System under this Regulation.

Proposal to introduce provisions relating to

• Manipulation Devices and Strategies that were previously in the 09 series of amendments to UN R83,
• the levels to which certain provisions apply,
• clarifications and corrections to the requirements for the laboratory test for pure electric range ratio at low temperature for Pure Electric Vehicles
• an update to allow the use in Levels 1A and 2 of actual tyre rolling resistance values to calculate the final road load coefficient for the individual vehicles, and
• align the Regulation with the current regional status and the current state-of-the-art.

Proposal to remove the provisions relating to manipulation devices and manipulation strategies that are being moved to UN R154 and clarify that in-service conformity checks for electric range of pure electric vehicles at low temperatures are optional.

Proposal to enable the approval of vehicles equipped with an Automated Driving System under this Regulation.

Proposal to amend Footnote 1 to reference ECE/TRANS/WP.29/78/Rev.8, amend para. 2.6. of Annex 1 to exclude driver mass for vehicles of categories X and Y, amend para. 3.4.3. of Annex 1 and para. 1.9.2. of Annex 2 to refer to user-selectable operating mode switch, amend para. 5.7.2. of Annex 4 to modify vehicle examination and maintenance checks, amend Table A4/2 of Annex 4 to add procedure to engage ADS testing mode, amend Appendix 1 to Annex 4 to modify examination lines, amend Appendix 5 to Annex 4 to replace driver with user-selectable mode references, insert new para. 3.4. and sub-paragraphs to Annex 6 for additional requirements for vehicles equipped with an ADS, and insert new para. 3.6. and sub-paragraphs to Annex 8 for additional requirements for vehicles equipped with an ADS.

Proposal to enable approval of vehicles equipped with an Automated Driving System under this Regulation.

Proposal to introduce in-service conformity requirements for system power.

Proposal to delete two paragraphs relating to “Operating Mode Switch” that were overlooked when that concept was removed from Regulation No. 83, from both the manufacturer’s information document (Annex 1) and the approval certificate addendum (Annex 2). The same documentation requirements were removed from the 08 series of amendments (during GREP-93), differing only in paragraph numbering.

Proposal to clarify Annex 3, table A3/1 regarding minimum type-approval requirements for Euro 6e, Euro 6e-bis, and Euro 6e-bis-FCM under UN R83 by specifying the relevant series of amendments for UN R24, R85, and R168, which were omitted when the 08 Series was created as no new amendments were anticipated at the time. A minor editorial correction is also included.

Proposal to correct several outdated references following structural changes to UN R154 (04 series of amendments), including updated appendix numbering in paragraphs 2.47, 2.48, and Annex 5, removal of “worst case certified energy consumption Part B family” from Table 4 reporting requirements, and correction of the vehicle survey reference to reflect its relocation to the 9 Series of amendments to UN R83.

Review of the different proposed amendments (03/04 series with different Supplements) to the regulations

Provides corrections and updates to the requirements, including to reflect the fact that requirements for manipulation devices and manipulation strategies

Current status of calculation method and component dynamometer tests

Proposal for change in transitional provisions to take into considerations of the lifetime value retention status

Proposal clarifies the OBFCM requirements

Proposal brings clarity to references and to correct copy & paste mistakes and possible misinterpretations related to in-vehicle battery durability and low
temperature.

Proposal clarifies the text relating to On-Board Diagnostics (OBD)

This Supplement proposes to update UN R154 to accommodate vehicles fitted with Automated Driving Systems (ADS), specifically categories X and Y. Amendments include new definitions for ADS-related terms, modifications to testing procedures, and updated references to vehicle construction standards. Driver-related systems are renamed to account for vehicles without human drivers. Special provisions establish requirements for ADS road load determination and testing modes, while messaging systems are adapted to send signals to ADS instead of or in addition to driver notifications.

Proposal to amend UN R180 to incorporate vehicles with Automated Driving Systems. Changes include adding ADS abbreviation and definitions for “ADS user” and “Vehicle user”; amending terminology throughout from “driver” to “vehicle user” or “driver and/or ADS”; introducing the Excess Exhaust Emissions Driver/user Warning System definition; modifying accelerator pedal references to include torque demand from ADS; and clarifying that warnings shall be sent to the ADS, which will then inform the relevant ADS user.
