Proposal to enable the approval of vehicles equipped with an Automated Driving System under the new UN Regulation on brake particle emissions.

Proposal to amend UN R179 Supplement 1:

• Modify the scope to include vehicles of category N₂ between 3.5 and 5 tonnes maximum mass at manufacturer request
• Add abbreviations and definitions including “Category M₁ vehicle”, “Mass in running order”, “Service brake”, “Brake calliper”, “User-selectable mode”, “ADS user”, and “Vehicle user”
• Amend the reference method to require testing on WLTP-Brake cycle using UN R154 compliant chassis dynamometer with external sensors for brake torque
• Specify vehicle selection procedures for testing user-selectable modes resulting in lowest recuperation with possible exemptions for very special limited purposes modes
