Abstract
Calibration and simulation techniques for modeled gear shift events of an automatic transmission of a vehicle comprise obtaining a set of parameters for a modeled gear shift event of the transmission and, based on the set of parameters, modeling forward/aft vehicle acceleration caused by the modeled gear shift event. A shift quality rating system is the utilized to obtain a shift quality rating of the modeled gear shift event based on at least one of the set of parameters and the modeled forward/aft vehicle acceleration. Finally, the techniques determine whether the determined shift quality rating satisfies a shift quality rating threshold and, when the determined shift quality rating fails to satisfy the shift quality rating threshold, a gear ratio gradient for the modeled gear shift event is adjusted and the process is repeated until the determined shift quality rating satisfies the shift quality rating threshold.
