1. Driving Indices and correction of test cycle flexibilities
J. Pavlovic, A. Marotta, B. Ciuffo WLTP 2nd Act Working Group Meeting Brussels - November 21st, 2017

2. Update Driving indices (all vehicles)
Correction procedure (no hybrids)

3. Driving indices (all vehicles)
Proposal
At the last telco of the DI Task Force, Japan has re-proposed the following validity criteria for the DI:
IWR < 0.8
RMSSE > - 2% and < + 4%
As the best compromise between the minimum possible variation of CO2/fuel consumption and the probability to have a valid test.
EC position: although the Correction procedure would allow the possibility of slightly wider validity margins, we could accept this proposal as harmonized solution in UNECE WLTP.

4. DIs proposals

5. Correction No threshold for the application of the CO2 correction
Once the test is considered valid, the calculation of the CO2 correction will be made anyway
Small CO2 corrections will also mean small error (if any)
Avoids any potential misuse (in either direction) of the CO2 correction mechanism
