Appendix 6

Selection of driver-selectable modes U.K.

1.General requirementU.K.

[F11.1. The manufacturer shall select the driver-selectable mode for the Type 1 test procedure in accordance with paragraphs 2. to 4. of this Appendix which enables the vehicle to follow the considered test cycle within the speed trace tolerances in accordance with paragraph 2.6.8.3. of Sub-Annex 6. This shall apply to all vehicle systems with driver-selectable modes including those not solely specific to the transmission. U.K.

1.2. The manufacturer shall provide evidence to the approval authority concerning: U.K.

(a)

The availability of a predominant mode under the considered conditions;

(b)

The maximum speed of the considered vehicle;

and if required:

(c)

The best and worst case mode identified by the evidence on the fuel consumption and, if applicable, on the CO 2 mass emission in all modes. See paragraph 2.6.6.3. of Sub-Annex 6;

(d)

The highest electric energy consuming mode;

(e)

The cycle energy demand (in accordance with Sub-Annex 7, paragraph 5. where the target speed is replaced by the actual speed).

1.3. Dedicated driver-selectable modes, such as mountain mode or maintenance mode which are not intended for normal daily operation but only for special limited purposes, shall not be considered.] U.K.

2.OVC-HEV equipped with a driver-selectable mode under charge-depleting operating conditionU.K.

For vehicles equipped with a driver-selectable mode, the mode for the charge-depleting Type 1 test shall be selected according to the following conditions.

[F1The flow chart in Figure A8.App6/1 illustrates the mode selection in accordance with this paragraph.]

2.1.If there is a predominant mode that enables the vehicle to follow the reference test cycle under charge-depleting operating condition, this mode shall be selected.U.K.

2.2.If there is no predominant mode or if there is a predominant mode but this mode does not enable the vehicle to follow the reference test cycle under charge-depleting operating condition, the mode for the test shall be selected according to the following conditions:U.K.

(a)

If there is only one mode which allows the vehicle to follow the reference test cycle under charge-depleting operating conditions, this mode shall be selected;

(b)

If several modes are capable of following the reference test cycle under charge-depleting operating conditions, the most electric energy consuming mode of those shall be selected.

2.3.If there is no mode according to paragraph 2.1. and paragraph 2.2. of this Appendix that enables the vehicle to follow the reference test cycle, the reference test cycle shall be modified according to paragraph 9 of Sub-Annex 1:U.K.

(a)

If there is a predominant mode which allows the vehicle to follow the modified reference test cycle under charge-depleting operating conditions, this mode shall be selected.

(b)

If there is no predominant mode but other modes which allow the vehicle to follow the modified reference test cycle under charge-depleting operating condition, the mode with the highest electric energy consumption shall be selected.

(c)

If there is no mode which allows the vehicle to follow the modified reference test cycle under charge-depleting operating condition, the mode or modes with the highest cycle energy demand shall be identified and the mode with the highest electric energy consumption shall be selected.

3.OVC-HEVs, NOVC-HEVs and NOVC-FCHVs equipped with a driver- selectable mode under charge-sustaining operating conditionU.K.

For vehicles equipped with a driver-selectable mode, the mode for the charge-sustaining Type 1 test shall be selected according to the following conditions.

[F1The flow chart in Figure A8.App6/2 illustrates the mode selection in accordance with this paragraph.]

3.1.If there is a predominant mode that enables the vehicle to follow the reference test cycle under charge-sustaining operating condition, this mode shall be selected.U.K.

3.2.If there is no predominant mode or if there is a predominant mode but this mode does not enable the vehicle to follow the reference test cycle under charge-sustaining operating condition, the mode for the test shall be selected according to the following conditions:U.K.

(a)

If there is only one mode which allows the vehicle to follow the reference test cycle under charge-sustaining operating conditions, this mode shall be selected;

(b)

If several modes are capable of following the reference test cycle under charge-sustaining operating conditions, it shall be at the option of the manufacturer either to select the worst case mode or to select both best case mode and worst case mode and average the test results arithmetically.

3.3.If there is no mode according to paragraph 3.1. and paragraph 3.2. of this Appendix that enables the vehicle to follow the reference test cycle, the reference test cycle shall be modified according to paragraph 9. of Sub-Annex 1:U.K.

(a)

If there is a predominant mode which allows the vehicle to follow the modified reference test cycle under charge-sustaining operating condition, this mode shall be selected.

(b)

If there is no predominant mode but other modes which allow the vehicle to follow the modified reference test cycle under charge-sustaining operating condition, the worst case mode of these modes shall be selected.

(c)

If there is no mode which allows the vehicle to follow the modified reference test cycle under charge-sustaining operating condition, the mode or modes with the highest cycle energy demand shall be identified and the worst case mode shall be selected.

4.PEVs equipped with a driver-selectable modeU.K.

For vehicles equipped with a driver-selectable mode, the mode for the test shall be selected according to the following conditions.

[F1The flow chart in Figure A8.App6/3 illustrates the mode selection in accordance with this paragraph.]

4.1.If there is a predominant mode that enables the vehicle to follow the reference test cycle, this mode shall be selected.U.K.

4.2.If there is no predominant mode or if there is a predominant mode but this mode does not enable the vehicle to follow the reference test cycle, the mode for the test shall be selected according to the following conditions.U.K.

(a)

If there is only one mode which allows the vehicle to follow the reference test cycle, this mode shall be selected.

(b)

If several modes are capable of following the reference test cycle, the most electric energy consuming mode of those shall be selected.

4.3.If there is no mode according to paragraph 4.1. and paragraph 4.2. of this Appendix that enables the vehicle to follow the reference test cycle, the reference test cycle shall be modified according to paragraph 9. of Sub-Annex 1. The resulting test cycle shall be named as the applicable WLTP test cycle:U.K.

(a)

If there is a predominant mode which allows the vehicle to follow the modified reference test cycle, this mode shall be selected;

(b)

If there is no predominant mode but other modes which allow the vehicle to follow the modified reference test cycle, the mode with the highest electric energy consumption shall be selected;

(c)

If there is no mode which allows the vehicle to follow the modified reference test cycle, the mode or modes with the highest cycle energy demand shall be identified and the mode with the highest electric energy consumption shall be selected.
