Basic policy of Multimode selection

Basic Policy

Data is necessary if frequent use is expected.

Data is not necessary if no frequent use is expected.

Multimode [Emission]

Official test by the worst case, but some exemption.

• Basically emission compliance is confirmed with all modes and official test is carried out by the worst case selection.

• However some operating modes should be exempted, which no frequent use is expected. For example Low and 2nd position of AT.

Mode

Official test is carried out by the worst case.

---An idea of regulation sentence---Emission compliance shall be confirmed with all selectable modes. However if the mode(s) are reasonably expected to use in very limited condition, the mode(s) are exempted with approval of authorities. The recommended situation for such modes should be explained to customer via owners manual.

* Cert. family criteria is separated issue. (Japanese reg. defines that AT & MT is different family.)

Multimode [Fuel Economy with Default mode]

On default mode.• Default mode is expected as frequently selected position.

• As our proposal, [Default mode] of AT with manual shift operation is considered as right side. ()

• According to above proposal, manual shift operation on AT is tested, or not.(*)

• On MT, Normal shift and GSI shift are tested and take average, because both shift should be used frequently.

• Exemption for emission compliance is also applied to fuel economy test.

Mode

In case that [Normal] position is default.

Average

1. The intial position is “D”(Auto mode).

2. To activate manual mode, shift lever needs to be operated by removing the hand from steering wheel.

1. The intial position is “D”(Auto mode).

2. To activate manual mode, just operate shift paddle, so no need to remove the hand from steering wheel.

2.2.

D(Auto mode) is Default position.Tested on Auto mode only.

D(Auto mode) is NOT Default position.Tested on Auto & Manual mode.

*Average of 2 data or only Auto mode depending on manual shift design.

Multimode [Fuel Economy with No default mode]

Best & Worst modes.• Since it is not sure which mode is frequently used due to no

default position, all modes should be tested.

• As our proposal, [Default mode] of AT with manual shift operation is considered as right side. ()

• According to above proposal, manual shift operation on AT is tested, or not.(*)

• On MT, Normal shift and GSI shift are tested and take average, because both shift should be used frequently.

• Exemption for emission compliance is also applied to fuel economy test.
