WLTP use of the gearbox: required data (Open issue item 6)

Document WLTP-08-11

4 November 2014

8th WLTP session (18-20 Nov 2014)

Open issue 6 “Use of the gearbox, required data” concerns the following:

modification of the definition of n_{min_drive} to make it more appropriate for modern engines and to make manipulations more difficult.
Addition of n_max to section 2 and amendment of required data because the current definition is not appropriate for low powered vehicles.
Replacement of P_normwot(n_{norm i, j}) in Section 2 (i) by P_wot(n_{i, j}) because there is no need for the normalisation.

8th WLTP session (18-20 Nov 2014)

5. | Main part & Cycle issues (Annex 1 & 2)

#6: Annex 2, section 2, use of the gearbox, required data (WLTP-08-11e, WLTP-08-12e)
A modified description for n_{min_drive} and a modified definition for n_max were developed by the task force and presented for adoption. The 2 proposals were adopted by WLTP IWG.

For the amendment of definition of n_{min_drive}, the perspective was given to have a proposal ready for adoption for IWG meeting #10.

For the calculation of gear use if separate groups of transmission ratios are available, the proposal to base the gear use determination on the group normally used for on-road operation was adopted by WLTP IWG. The wording needs to be improved regarding “range” (B. Coleman, Drafting Coordinator).

Definition of exception of crawler gears in current gtr was discussed in TF without conclusion. Timeframe was extended to IWG meeting #10.
