JAMA position on RDE Boundary Condition 1

Boundary Condition – (1) JAMA PEMS Random Cycle Environmental Condition Ambient Temperature 10’C to 30’C, Hot Start 10’C to 30’C + Family Concept, Hot start Ambient Humidity Correction to average humidity ← Ambient Altitude Upper limit to the average hight of metropolitan cities（about 700m?） Oppose due to big influence on test facility Driving Condition Definition of L/M/H Shares of L/M/H Depending upon market driving data Average Speeds of L/M/H No need to set out. It will be covered by the market driving data above. No need to set out. Idling percentages for L/M/H Driving dynamics (vehicle accelerations) Data for extreme acceleration (vehicle performance > 90%) should be excluded. (This idea has been approved already in RC discussion) (1) If the ratio of window including extreme acceleration is more than 10%, the test should be void, or (2) If extreme acceleration (vehicle performance > 90%) lasts more than xx seconds, the test should be void . Upper limit is [90]% of max speed X acceleration Road grade Upper limit depending upon actual topographic data Not necessary (because it is reproduced by load condition of ST)

Boundary Condition – (2) JAMA PEMS Random Cycle Test Procedure Total test duration Same condition as HDV (More than 5 times compare to CO2 certification) NEDC - WLTC Number of Speed phases 3 Driving Condition (Rules for excluding trips etc) Same as above noted [Driving condition] ← Decision on the analysis of idling Based on Market data Correction factors for emissions Necessary to correct using CO2 and temperature, oppose to other corrections that there could be CF=1 Total number of short trips (ST) N/A Give priority to total length of cycle L/M：3±1、H；2±1 Initial source of ST Number of ST in the data base Gear Shifting strategy 1. GSI 2. Validate after testing, if there are big difference from GSI, that shift should be void AT/MMT/CVT as it is WLTC shift or GSI

Boundary Condition – (3) JAMA PEMS Random Cycle JAMA Proposal to ADD Condition to start testing Hot 【Justification】 -Necessary to do Hot test -Lack of soak room for cold test, big influence on test facility -Test time/cost of re-test for cold test, -Risk of frequent re-test (because proficiency driving is impossible) Pollutants to be measured NOx only All Duration for testing Daytime N/A Vehicle Weight RM + 60 kg or less ← Climate Same condition as HDV (“Normal” climate) Fuel Same fuel as Emission testing
