setting points. At each setting point, the chassis dynamometer shall be set to thevalue Fpau(vj) obtained in paragraph 7.2.2.2.4.7.2.2.2.5.2. Chassis dynamometer with coefficient controlIn the case of a chassis dynamometer with coefficient control, in which theabsorption characteristics are determined by given coefficients of a polynomialfunction, the value of Fpau(vj) at each specified speed should be calculated by theprocedure in paragraph 7.2.2.2.Assuming the load characteristics to be:v2Fpau a v bv cEquation 7-6where:the coefficients a, b and c shall be determined by the polynomial regression method.The chassis dynamometer shall be set to the coefficients a, b and c obtained by thepolynomial regression method.7.2.2.2.5.3. Chassis dynamometer with F * polygonal digital setterIn the case of a chassis dynamometer with a polygonal digital setter, where a centralprocessor unit (CPU) is incorporated in the system, F * is input directly, and t i, Ffand Fpau are automatically measured and calculated to set the chassis dynamometerto the target running resistance forceF* * * 2 f f2 v .In this case, several points in succession are directly input digitally from the data setof F* j and vj, the coast down is performed and the coast down time t j is measured.After the coast down test has been repeated several times, Fpau is automaticallycalculated and set at motorcycle speed intervals of 0.1 km/h, in the followingsequence:13.6*F Ff mi mr12ΔvΔtiEquation 7-7Ff13.62Δv*m m ir1 FΔtiEquation 7-8FpauF* F f Equation 7-97.2.2.2.5.4.
