1 Test program application and preliminary results France ASEP-05-10

2 Tests and analysisto bedone The group requests GRB members to deliver data for the next meeting under ASEP Rev Test program for a single vehicle for the developmentofasep.atleast2datasets: Oneonlockedgearconditionand asecondonnon-lockedgearconditionsorhevoranynew technology vehicle. Preliminary investigation was done on one vehicle tested on locked and non-locked conditions

3 Test Program application UN R51.03 annex 3, on gear 2 to 5 and D

4 Test Program application Wot on control range, on gear 2 to 5 and D

5 Test Program application From crsto wot on control range, on gear 2 to 5 and D

6 Test Program application Partial throttle : Difficulties to manage target acceleration with target speed Variability of acceleration level with approach speed for a target speed Partial throttle wot

7 Test Program application Partial throttle: Difficulties to manage useful pedal range especially for high speed Testweredoneusingshimforthrottlesteps(14): 6 14

8 Test Program application Partial throttle : Difficulties to manage non-locked conditions Wot+2levelsofpartialthrottleweretargeted

9 Test Program application To beclarify: Speed (engine speed) target for ASEP Tests. Acceleration target for ASEP Tests. Add cruise test for ASEP tests. Need or not to have same target speed for wot, pot and crs. Non-locked conditions. To bedefined: Potential range of partial subject to doubt

10 Test results : The cloud UN R51.03 annex 3 + from crsto wot on gear 2 to 5 Total vehicle sound level

11 Test results : The cloud UN R51.03 annex 3 + from crsto wot on gear 2 to 5 Total vehicle sound level

12 Test results : The cloud Some point were excluded from the cloud because of nonunderstanding behaviourfor vehicle and/or propulsion sound level : High speed : > km/h High acceleration More analysis shall be made to understand

13 Partial throttle: @BB

14 Partial throttle: Behaviour Lockedcondition : Usingshimfor throttlesteps(14) Non lockedcondition : 6 14

16 Partial throttle: Behaviour Lockedcondition :

17 Partial throttlebehaviour Non lockedcondition :

18 Partial throttle : Repeatability Using shim for throttle step Similar repeatability

19 The cloud : Analysis (locked cdt) Wot on gear 3 to 4 Total vehicle + propulsion sound level

20 The cloud : Analysis (locked cdt) Wot on gear 3 to 4 Total vehicle + propulsion sound level

21 The cloud : Analysis (locked cdt) Crsto Wot on gear 2, 3 to 4 Total vehicle + propulsion sound level Veh Prop

22 The cloud : Analysis (locked cdt) Crsto Wot on gear 2, 3 to 4 Total vehicle + propulsion sound level Veh Prop

23 The cloud : Analysis (locked cdt) Crsto Wot on gear 2, 3 to 4 Propulsion sound level

24 Stationary Stationary was perform 2 times (with repetitions) : right + 20 cm Left+ 20 cm

25 Crsto Wot on gear 2, 3 to 4 Propulsion sound level Preliminary results Stationary

26 The cloud : Non locked conditions Crsto Wot on gear 2, 3 to 4 Total vehicle + propulsion sound level Veh Prop

27 First test Results Partial throttle: Annex3 issue Comparisonbetween: L urb calculedfroml wot and L crs on lockedcondition L urb calculedfroml wot and L crs on non-lockedcondition L partial throttle Deviation between calculated and measured partial throttle levels is higherfor non-lockedcondition thanlockedcondition.

28 Conclusions Test Program is applicable with some difficulties for partial throttle and non-locked conditions. Furthermore, it could be time consuming. The way to analyze the cloud has to be define to interpret consistency of results, single vehicle model and abnormal deviations. Partial throttle for Annex 3 seems to be applicable. Partial throttle testing method should be more described for application.
