  3. 1. Progress since 64th GRPE ’12/5 6 7 8 9 10 11 12 ’13/1 13th DHC 14th DHC 15th DHC • Agreed to apply Ver5.1 (Vmax.≦120km/h) • Agreed cycle allocation • Proposed cycle profile modification(ver5.3) for Class 3 by India Proposed cycle profile modification(ver5.1) for Class 3 by Japan • Provisionally agreed to apply Ver5.1 (Vmax.≦120km/h) • Decided to set mode construction task force for detailed discussion Cycle Validation 2 Test Adopt HS3 logic during Validation2 • Confirmed well work • No major concern • Continue improvement Gear shift Work under DHC Work under MCTF Mode Construction • List up discussion points • Set proposals on several points • Still remain discussion points Technical Report Complete by 66th GRPE (JRC, Mr. Steven and JPN) • Developed outline of contents • 1st version 3

  4. 2. Finalized Cycle Profile During 16th DHC meeting, it was agreed to modify the cycle profile (Ver5.3 proposed by India) for Class3. DHC has successfully developed the harmonized test cycles. Specific time table of each cycle profile can be seen in WLTP-DHC-16-06 (UN web site) Ex-HIGH for Class2 HIGH MIDDLE LOW for Class3 HIGH MIDDLE for Class1 MIDDLE LOW LOW Ex-HIGH

  5. 3-1. Cycle Allocation L + M + H + ExH *1/*2 L + M + H Class 3 (= Ver5 or Ver5.3) (= Ver 5.1) 34 Power Mass* Ratio (kW/t) Class 2 L + M+ L L + M+ H L + M+ H+ ExH *1 22 L + L+ L L + M+ L Class 1 70 90 120 135 Mass* = Kerb Mass Vehicle Max Speed (km/h) During 15th DHC meeting (Dec 2012), the following cycle allocation was agreed. Threshold for electrified vehicles is under the discussion among DTP-Elab subgroup. *1) exempted as per CPs need *2) capped speed according to vehicle maximum speed 5

  6. 3-2. Alternative Cycle Allocations During 16th DHC meeting, the following cycle allocations were proposed by Germany for alternative to avoid special design for cycle allocation (refer WLTP-DHC-16-04). note) Ex-H phase can be exempted as per CPs need 6

  7. 3-3. Threshold speed of Cycle Allocations During 16th DHC meeting, India has proposed to set margin for capped cycle speed by 15% (refer WLTP-DHC-16-05). On the other hands, EU and Korea have expressed their concerns stating that margin should be minimized as much as possible. [ Request to all CPs ] Each CP is requested to provide their written comments regarding both alternative cycle allocation and threshold speed by no later than 1st Feb. 2013 to DHC chairman and secretary. ishii@ntsel.go.jp, nick@ichikawa.tec.toyota.co.jp 7

  8. 4. Gear Shift Prescription (Steven3) Mr. Steven has presented latest status of gear shift prescription (refer WLTP-DHC-16-03). • Validation 2 test indicated that this gear shift logic works well and no major concern was observed. Based on comments provided from participant laboratories, continue to work for improvement, then provide final version before starting confirmation testing. 8
