5. IMMA proposal presented at 12th IWG ASEP (China) ASEP 2. 0 rev
IMMA proposal presented at 12th IWG ASEP (China) ASEP 2.0 rev.0 „any throttle“ Formal & informal feedback from IWG ASEP Stakeholders:
‘any throttle’:
Lack of repeatability in testing
Difficulty in demonstrating the vehicle operation was in accordance with the instructions given by the TS personnel throughout the test.
Number of test points
(principle agreement on expanded speed & rpm window)

6. Revised IMMA ASEP 2.0  ASEP 2.0 rev. 1
the revised procedure „splits“ the test in two phases
„real driving“ approach  before AA’ (NEW)
measurement area  between AA’ and BB’
„real driving“ approach:
Any throttle operation, to reflect vehicle operation close to real driving conditions
Current R41-04 requires only constant approach speed (fixed speed)
Before AA‘ the motorcycle can vary its velocity „significantly“
prescribed test speed vtest at AA‘ +/- [ 5 ]km/h
measurement area:
similar to current Annex 7 test, but with the possibility to apply:
WOT
Any partial, constant throttle
(including constant speed)
