# 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 8.1.4: Adjustment


The chassis dynamometer setting load shall be adjusted according to the following equations:
F*dj=Fdj− Fj=Fdj− Fsj+ Ftj=Ad+ Bdvj+ Cdv2j−As+ Bsvj+ Csv2j+At+ Btvj+ Ctv2j=Ad+ At− As+Bd+ Bt− Bsvj+Cd+ Ct− Csv2jTherefore:
A*d=Ad+ At− AsB*d=Bd+ Bt− BsC*d=Cd+ Ct− Cswhere:
Fdjis the initial chassis dynamometer setting load, N;
F*djis the adjusted chassis dynamometer setting load, N;
Fjis the adjustment road load equal to (Fsj - Ftj), N;
Fsjis the simulated road load at reference speed vj, N;
Ftjis the target road load at reference speed vj, N;
A*d, B*d and C*dare the new chassis dynamometer setting coefficients.
