Comparison of the behaviour from FlexPLI and Human Model THUMS in the outer area of the bumper.

Review of test results applying the Flex PLI and EEVC legs outside the regulatory bumper test area.

Review of the European validation program to assess the repeatability of the test procedure described in the Phase 1a GTR text.

Presentation on the use of “sailing” technologies to reduce CO₂ emissions and raising a question over the ability of the WLTP test cycle to account for the effect of sailing on vehicle emissions and fuel consumption performance. Sailing involves the decoupling of the engine from the drive shaft, enabling hybrid vehicles to cruise (or “sail”) on battery power alone until such time as the engine needs to be restarted to generate electricity and/or resume the torque functions.

Presentation of ACEA concerns over the TRL proposal to adapt the GTR No. 9 test procedures to use 45° bumper corners.

ACEA proposes to align the GTR text with the HEV definition used in the EC directive 692/2008/EC (Type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6)).

Discussion of utility factors used in weighting emissions and fuel consumption. Utility factors are ratios based upon driver statistics and vehicle ranges recorded by off-vehicle charging (OVC) hybrid electric vehicles (HEV) (i.e., plug-in hybrid electric vehicles) in charge-depleting and charge-sustaining modes.

Proposal to maintain regulatory language to ensure that vehicles cannot be mis-fueled with a fuel (diesel, leaded or unleaded gasoline, etc.) other than that for which the vehicle is designed.

WLTP Phase 1b: Generic formula for hydrocarbon density

Draft revision 01 (second issue) of the draft new regulation on uniform provisions concerning the approval of dual fuel retrofit systems to be installed on heavy duty diesel engines and vehicles submitted by ACEA. The previous version (Revision 00: first issue) was submitted by the AEGPL.

ACEA proposal for defining a hybrid key function (torque split for parallel hybrids and energy management for serial hybrids) in the configuration of HILS software in the testing heavy-duty hybrid vehicles. ACEA also proposes to exclude “micro” hybrid systems (i.e., 48-v based systems) used to supplement the internal combustion engine as a means to reduce CO₂ emissions and improve fuel efficiency. The exclusion criteria would be based upon the ratio of positive electrical power to total system power (to be defined).

Proposal to add a generic formula for the density of total hydrocarbons to GTR No. 15 as part of phase 1b of its development.

ACEA background information to support a discussion on the flow and number of tests to be conducted under the WLTP procedures.

Open issues list items 56 and 2.

ACEA recommendation concerning the calculation of the CO2 value for an individual vehicle by the CO2 interpolation method (No addition of Matlab formulae in the GTR.)

Draft GTR text with highlighted changes

Presentation on post-processing procedures for OVC-HEV and PEV (Shortened Test Procedure).

Particle numbers are measured via partial dilution or CVS systems under current emissions regulations. This presentation provides information in support of heavy-duty vehicle/engine manufacturer interest in direct measurement of raw PN emissions. ACEA requests the PMP program to further investigate the feasibility to allow PN raw measurement for HD applications.

Information on Swiss detection of significant deactivation of Ad Blue diesel emissions reduction systems on EURO V vehicles (no EURO VI manipulated vehicles have been found to date).

Discussion of CO₂ measurements and root mean squared speed error (RMSSE) pursuant to round robin methodology validation testing in Europe.

PMP tailpipe sampling.

ACEA translation of China text for automated vehicles development.

ACEA translation of China text for Intelligent and Connected Vehicles.

Proposal to avoid unnecessary testing without additional value (updated proposal after 05.03.2020 – revision 2)

Updated slides pursuant to the 42nd EV subgroup session.

Vehicle survey for use in the verification of battery durability in certain cases.

Study to evaluate the potential and the feasibility of limit value reductions in type approval and the translation to real road traffic conditions
