WLTP, RESULT CALCULATION, V4 MEASURED RESULT IS CORRECTED BY RCB, KI, 14° TEST AND INTERPOLATION. BMW, Christoph Lueginger WLTP-12-08e

WLTP RESULT POSTPROCESSING PROPOSAL CURRENT SITUATION 2 WLTP Postprocessing, Result Calculation, BMW,  All GTR post-calculations have been developed regardless of other parts and issues.  Some references are wrong, some results come to nothing, some results are bypassed.

WLTP RESULT POSTPROCESSING PROPOSAL 3 WLTP Postprocessing, Result Calculation, BMW, measurement, calculation of mass emissions [Annex 7, 3.] test RCB correction [Annex 6, App. 2] RCB calculation of fuel consumption values [Annex 7, 6.] FC Ki correction [Annex 6, App. 1] Ki Regional corrections (EU: 14° test, DF) [e.g. EU Sub-Annex 6a] regional combined value (3-/4-phases, weighted by distance) [unclear] comb. ( ) averaging of test results, alignment of phase values [Annex 6, Japanese proposal] AVG interpolation method, rounding. (Europe  "CoC") [Annex 7, ] vehicle declared value, regional differences [Annex 6, Japanese text proposal] declare averaging of emissions L and H, final interpolation line [open] approval phase CO 2 comb. emiss. phase emiss. phase CO 2 comb. emiss. phase CO 2 phase FC comb. emiss. phase CO 2 comb.

WLTP RESULT POSTPROCESSING PROPOSAL CHALLENGES AND OPEN TASKS 4 WLTP Postprocessing, Result Calculation, BMW, stepstasksituation 1 agreement on importance, agreement being a GTR issue, installation of TF the need was already identified in the last drafting-TF-meeting 2identify all calculation stepsdone for ICE and EV 3 decide their order, decide which errors can be accepted, clarify overlapping issues ICE-EV proposal for ICE available 4drafting of main structureproposal for ICE available 5drafting within each calculation stepopen 6check by stakeholders and testing (via a tool?)open phase specific values additive corrections (step exchange will deliver different results) averaging of tests influence of criteria emissions on FC declaration (alignment of values like FC and phases towards the declared value) regional options solution today's task ?
