Abstract
Control systems and methods for a vehicle transmission initiate a shift operation of the transmission and, during the transmission shift operation, determine an acceleration of a torque generating system output shaft based on its measured rotational speed and determine an acceleration of the transmission output shaft based on its measured rotational speed, identify an error source using a transmission model that maps differences between the determined and target accelerations back to torque generating system error and/or transmission clutch torque error and, based on the identified error source, adjust the actuation of at least some of the plurality of clutches to compensate for the torque generating system error and/or transmission clutch torque error to mitigate or eliminate noise/vibration/harshness (NVH) caused by the transmission shift operation.
