# 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 3.3: Selection of possible gears with respect to engine speed


The following gears may be selected for driving the speed trace at vj:
(a)All gears i < ngvmax where nmin_drive ≤ ni,j ≤ nmax1;
(b)All gears i ≥ ngvmax where nmin_drive ≤ ni,j ≤ nmax2;
(c)Gear 1, if n1,j < nmin_drive.
If aj < 0 and ni,j ≤ nidle, ni,j shall be set to nidle and the clutch shall be disengaged.
If aj ≥ 0 and ni,j < max(1,15 × nidle; min. engine speed of the Pwot(n) curve), ni,j shall be set to the maximum of 1,15 × nidle or (n/v)i × vj and the clutch shall be set to ‘undefined’.
‘undefined’ covers any status of the clutch between disengaged and engaged, depending on the individual engine and transmission design. In this case the real engine speed may deviate from the calculated engine speed.
