Coastdown testing is an acceptable technique for establishing the dynamometer load which simulates the vehicle road load during EPA dynamometer fuel economy and emission testing.
This paper discusses the theoretical basis of a successful approach to coastdown testing. Corrections for the effects of ambient conditions on road test results are defined, and a data-efficient method of matching the dynamometer to road load is discussed.
