Proposal to correct the calculation of the coast-down resistance to progress force.

Proposal to correct the calculation of the coast-down resistance to progress force.

Proposed amendment to complete the Phase 1 development of the light vehicle emissions GTR. This amendment addresses:

• Conventional ICE vehicles
  • Normalisation methods and speed trace index;
  • Number of tests;
  • Wind tunnel as alternative method for road load determination;
  • Road load matrix family;
  • Interpolation family and road load family concept;
  • On-board anemometry and wind speed conditions;
  • Alternative vehicle warm-up procedure; and
  • Calculation and interpolation of fuel consumption.
• Electrified Vehicles
  • Fuel cell vehicle test procedure;
  • Shortened test procedure for PEV range test;
  • Phase-specific CO2 (fuel consumption) for Off-Vehicle Charging Hybrid Electric Vehicles (OVC-HEVs);
  • End of EV range criteria;
  • Interpolation approach for OVC-HEVs and PEVs;
  • Utility factors; and
  • Predominant mode / mode selection.
• Alternative pollutants
  • Measurement method for ammonia, ethanol, formaldehyde and acetaldehyde.
• Development of Harmonized Cycle (DHC)
  • Further downscaling in Wide Open Throttle (WOT) operation; and
  • Gear shifting.

Detailed report on the decisions and rationale involved in the development of the amendment to complete the Phase 1 development of the global technical regulation on light vehicle emissions.

Proposal to begin work on the second phase development of the light vehicle emissions GTR, covering:

• Remaining items from the original authorization (WP.29/AC.3/26)
• Open issues remaining under Phase 1b
• Durability of internal combustion engine vehicles and electric vehicles
• Evaporative emissions
• Low ambient temperature emissions
• Test procedure for the determination of additional CO2 emissions and fuel consumption from mobile air conditioning systems
• On-board diagnostics requirements
• Development of criteria for ex-post assessing of road load parameters (document WLTP-12-29-rev1e), and
• “Other items” as may arise.
