Vehicle operation on 8.65″ uncoupled twin-roll hydrokinetic and 48″ single-roll dynamometers was analyzed for speed, road load, and inertia simulation differences. Tire slip measurements were used to determine generic coefficients accounting for differences on the two dynamometers. Control methods were developed to use operational speed and load measurements on the 48″ dynamometer to predict the instantaneous rear roll speed which would have occurred on the twin rolls, and to compute instantaneous load corrections on the 48″ dynamometer to simulate the twin-roll dynamometer. Emission and fuel economy tests were run to evaluate simulation effectiveness.
