# Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008 (Text with EEA relevance), Division 8.2.3.2


The simulated running resistance (torque) curve on the chassis dynamometer shall be calculated according to the method described and the measurement precision specified in paragraph 4.4.3.2. of this Sub-Annex, and the running resistance (torque) curve determination as described in paragraph 4.4.4. of this Sub-Annex with applicable corrections according to paragraph 4.5. of this Sub-Annex, all with the exception of measuring in opposite directions, resulting in a simulated running resistance curve:
C*s=C0s+ C1s× vj+ C2s× v2jThe simulated running resistance (torque) shall be within a tolerance of ± 10 N×r’ from the target running resistance at every speed reference point where r’ is the dynamic radius of the tyre in metres on the chassis dynamometer obtained at 80 km/h.
If the tolerance at any reference speed does not satisfy the criterion of the method described in this paragraph, the procedure specified in paragraph 8.2.3.3. of this Sub-Annex shall be used to adjust the chassis dynamometer load setting.
